Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.

In industrial production or energy supply departments, waste materials harmful to human bodies and the environment are often generated, so that the waste materials need to be stored in a sealed mode to prevent the waste materials from influencing the health of people or polluting the environment. Especially for the radioactive spent fuel, the sealed storage condition is more severe.

At present, most of containers specially made are used for packaging waste materials, and in the process of packaging the waste materials, how to avoid the waste materials from polluting air or endangering human health is achieved, and the reliable isolation of the inner cavity of the container from the external environment is ensured, so that the technical problems which exist generally and need to be solved urgently are solved.

In view of the above, the present invention provides a waste packaging system 100, which can store the waste in a waste box 250 in a container 240, wherein the waste box 250 is provided with a discharge opening 201.

The waste packaging system 100 provided by the invention utilizes the sealing body 230 to package the waste discharged into the container 240 through the discharge opening 201 into the inner cavity of the container 240 so as to isolate the waste from the external environment gas of the container 240, and the waste box 250 is always sealed and isolated from the external environment in the waste discharging and packaging processes of the container 240.

Please refer to fig. 1, fig. 2 and fig. 7. FIG. 1 is a schematic diagram of a portion of a waste packaging system 100 according to an embodiment of the present invention; FIG. 2 is a schematic perspective view of a waste packaging system 100 according to an embodiment of the present invention; figure 7 is a schematic view, partially in section, of the waste encapsulation system 100 shown in figure 2.

The scrap packing system 100 according to the present invention includes a transfer mechanism 10 provided outside a scrap box 250, a joining mechanism 20 provided slidably to the transfer mechanism 10, and a welding mechanism 30.

When the waste packaging system 100 is used for packaging radioactive waste, the internal space of the waste bin 250 is radioactive, the internal air is in a contaminated state, and the outside of the waste bin 250 is not contaminated by the radioactive waste, i.e. the outside of the waste bin 250 is clean air, and the transferring mechanism 10, the bonding mechanism 20 and the welding mechanism 30 are all in a clean environment without radiation.

In the existing waste packaging operation, gas inside a waste box can be difficultly dissipated outside the waste box, and the gas flows to cause pollution of clean gas outside the waste box, so that the health of personnel and the external environment are influenced. Therefore, how to ensure that the environment outside the waste bin is not polluted and radiated in the process of packaging the waste in the waste bin into the container is a difficult problem in the field of nuclear waste treatment at present.

The transfer mechanism 10 is used for transferring the joining mechanism 20 and the cleaning container 240 which has not accommodated the waste; the joining mechanism 20 can move synchronously with the transferring mechanism 10 to obtain the container 240 and can drive the container 240 to move towards the discharge opening 201 of the waste bin 250, so that the container 240 is in sealed communication with the discharge opening 201, and waste in the waste bin 250 is convenient to transfer into the container 240; the welding mechanism 30 is used to seal and weld the seal body 230 to the inner wall of the container 240 after the scrap material enters the container 240, thereby separating the interior of the container 240 from the environment outside the container 240.

The container 240 is in sealed communication with the discharge opening 201, specifically: the interior of container 240 is in communication with the interior of waste bin 250 via discharge port 201, and at the same time, a sealed connection is formed between container 240 and waste bin 250, so that neither the gas in the interior of container 240 nor the interior of waste bin 250 escapes to the exterior of container 240 or waste bin 150 via the opening in container 240 or discharge port 201.

When the waste packaging system 100 is used to process radioactive waste, the transfer of the container 240 and the welding of the seal body 230 to the container 240 are performed in a clean environment.

Referring to fig. 3 to 6, fig. 3 is a schematic perspective view of the waste packaging system 100 shown in fig. 1 at a second viewing angle; FIG. 4 is a perspective view of the waste packaging system 100 of FIG. 1 from a third perspective; FIG. 5 is a schematic perspective view of the scrap encapsulation system 100 of FIG. 1 with the welding mechanism 30 and the cutting mechanism 40 omitted; fig. 6 is a schematic diagram of a portion of the waste packaging system 100 shown in fig. 1.

In one embodiment, waste packaging system 100 further includes a container positioning mechanism (not shown) and a discharge mechanism 210. The container positioning mechanism comprises a container positioning unit for holding the cleaning container 240, and the discharging mechanism 210 is installed on one side of the waste bin 250 facing the waste packaging system 100 and is provided with a discharging opening 201 communicated with the inner cavity of the waste bin 250. The transfer mechanism 10 includes a first transfer unit 11 fixedly provided and a second transfer unit 12 slidably provided on the side of the first transfer unit 11 relatively close to the discharge mechanism 210, and the joining mechanism 20 is slidably attached to the second transfer unit 12.

In the present embodiment, the discharge mechanism 210 is disposed on the side of the waste bin 250 facing the ground, and is suspended above the transfer mechanism 10, and the discharge opening 201 is opened vertically downward. The first transfer unit 11 includes a first rail 111 extending in the horizontal direction, and the second transfer unit 12 is slidably engaged with the first rail 111. The first transfer unit 11 has a first preset position and a second preset position, which correspond to two limit positions of a sliding track formed by the second transfer unit 12 on the first transfer unit 11.

Further, the second transfer unit 12 includes an elevation rail 121 extending in the vertical direction, that is, in the direction parallel to the axis of the discharge port 201, and the engagement mechanism 20 forms a sliding fit with the elevation rail 121. When the container 240 is mounted on the joining mechanism 20 and the joining mechanism 20 drives the container 240 to move vertically relative to the second transfer unit 12, the axis of the container 240 is kept parallel to the vertical direction.

When the second transfer unit 12 slides along the first guide rail 111 to the first preset position, the joining mechanism 20 and the discharge port 201 are disposed opposite to each other in the vertical direction, and at this time, if the container 240 is mounted on the joining mechanism 20, the axis of the container 240 coincides with the axis of the discharge port 201. Thus, at this time, the second transfer unit 12 can guide the joining mechanism 20 to move toward the discharging mechanism 210 by the lifting rail 121 until the container 240 communicates with the discharge opening 201.

When the second transfer unit 12 slides along the first guide rail 111 to the second preset position, the engaging mechanism 20 and the container positioning unit are disposed opposite to each other in the vertical direction, and at this time, the second transfer unit 12 can guide the engaging mechanism 20 to move toward the container positioning unit, so that the container positioning unit releases the cleaning container 240, thereby mounting the container 240 to the engaging mechanism 20.

It is understood that in other embodiments, the first rail 111 may not necessarily extend in a horizontal direction; the lifting rail 121 may not necessarily extend in the vertical direction. For example, when the discharge opening 201 is opened in the horizontal direction, the second transfer unit 12 guides the joining mechanism 20 to move toward the discharge mechanism 210 in the horizontal direction, and at this time, if the container 240 is mounted on the joining mechanism 20, the container 240 is disposed opposite to the discharge opening 201 in the horizontal direction; the waste bin 250 may not be suspended from the waste packaging system 100.

Specifically, the first transfer unit 11 further includes a first transmission shaft 112 parallel to the first guide rail 111, a screw transmission portion is provided on an outer periphery of the first transmission shaft 112, and the second transfer unit 12 includes a first translation sliding portion 124 slidably fitted to the first guide rail 111 and screw-fitted to the first transmission shaft 112, so that the first translation sliding portion 124 and the first transmission shaft 112 are relatively screw-movable.

One end of the first transmission shaft 112 forms or is provided with a first power input 71 for driving connection with an external drive source. The first transmission shaft 112 is driven by the external drive source to move spirally with respect to the first translational slide portion 124, and the first guide rail 111 restricts the first translational slide portion 124 from rotating with respect to the first transfer unit 11 and allows the first translational slide portion 124 to translate along the first guide rail 111.

Preferably, in the present embodiment, a rolling body is provided between the first transmission shaft 112 and the first translational sliding portion 124, and the rolling body is in rolling contact with the first transmission shaft 112 and the first translational sliding portion 124, respectively, and can roll along the screw transmission portion. Therefore, a ball screw fit is formed between the first transmission shaft 112 and the first translational sliding part 124, and the ball screw fit has the advantages of smooth transmission, long service life and capability of bearing large load.

Of course, in other embodiments, the relative screwing motion between the first transmission shaft 112 and the first translational sliding portion 124 may be achieved by a threaded fit.

Specifically, the second transfer unit 12 further includes a second transmission shaft 122 parallel to the elevation guide 121, the second transmission shaft 122 is provided at an outer periphery thereof with a screw transmission portion, and the engagement mechanism 20 includes a second translational sliding portion 211 slidably fitted to the elevation guide 121 and screw-fitted to the second transmission shaft 122, so that the second translational sliding portion 211 and the second transmission shaft 122 are capable of relative screw movement.

Further, the first transferring unit 11 further includes a third transmission shaft 113, one end of the third transmission shaft 113 is formed or provided with a second power input end 72 for driving connection with an external driving source; the third transmission shaft 113 is further provided with a first driving gear 1131, one end of the second transmission shaft 122 extends toward the first transfer unit 11 and is provided with a first driven gear 1221, and the first driving gear 1131 is engaged with the first driven gear 1221.

Under the driving of the external driving source, the third transmission shaft 113 drives the second transmission shaft 122 to rotate through gear engagement, the second transmission shaft 122 moves spirally relative to the second translational sliding portion 211, the elevation guide rail 121 limits the rotation of the second translational sliding portion 211 relative to the second transfer unit 12, and allows the second translational sliding portion 211 to translate along the elevation guide rail 121. This realizes that the second transfer unit 12 guides the engagement mechanism 20 to slide along the elevation rail 121.

Preferably, in the present embodiment, the second translational sliding portion 211 is in threaded engagement with the second transmission shaft 122. Of course, the second translational sliding portion 211 and the second transmission shaft 122 may be transmitted by means of a ball screw.

In one embodiment, the engagement mechanism 20 includes a first lifting unit 21 slidably mounted to the lifting rail 121, and a rotating clamp unit 22 mounted to the first lifting unit 21 in a follow-up manner. The second transfer unit 12 can guide the first elevation unit 21 and the rotary clamping unit 22 to synchronously move towards the discharging mechanism 210 through the elevation guide rail 121; the rotating and clamping unit 22 can drive the cleaning container 240 to move towards the discharging mechanism 210 along with the first lifting unit 21, and can drive the container 240 to rotate relative to the second transferring unit 12 after the container 240 is communicated with the discharging opening 201.

Specifically, the first lifting unit 21 includes the second translational sliding portion 211 configured to slidably engage with the lifting rail 121, and the rotary driving unit 212 attached to the second translational sliding portion 211, wherein the rotary driving unit 212 is configured to generate power for driving the container 240 to rotate relative to the second transfer unit 12. The output end of the rotary driving component 212 is provided with a first transmission gear 213; the rotary clamping unit 22 is rotatably disposed on the second translational sliding portion 211, and a second transmission gear 214 engaged with the first transmission gear 213 is disposed on an input end thereof.

Further, the rotary clamping unit 22 comprises a pivot part 221 which is connected with the second transmission gear 214 in a follow-up manner, and a clamping part 222 which is connected with the pivot part 221 in a follow-up manner, wherein the clamping part 222 comprises a plurality of clamping claws which are annularly arranged and used for clamping the outer peripheral wall of one end of the container 240 which is relatively far away from the discharging mechanism 210. When the rotation driving assembly 212 outputs a driving force to the first transmission gear 213, the second transmission gear 214 drives the pivot portion 221 to rotate relative to the second translational sliding portion 211, and simultaneously drives the container 240 to rotate relative to the second transfer unit 12 through the engaging portion 222.

It will be appreciated that in other embodiments, the rotary drive assembly 212 may be drivingly connected to the rotary clamping unit 22 in other manners, such as a belt drive connection.

In one embodiment, the welding mechanism 30 includes a laser welding unit 31, and the laser irradiation direction of the laser welding unit 31 is perpendicular to the trajectory along which the joining mechanism 20 slides with respect to the second transfer unit 12. After the waste material is loaded into the container 240 through the discharge opening 201 and the sealing body 230 is loaded into the container 240, the rotating clamping unit 22 drives the container 240 to rotate relative to the laser welding unit 31 through the clamping portion 222, and meanwhile, under the irradiation of the laser welding unit 31, a welding seam which extends along the circumferential direction of the container 240 and is closed is formed between the sealing body 230 and the inner wall of the container 240.

Specifically, the welding mechanism 30 further includes a first upright column 32, and the first upright column 32 is fixedly disposed with respect to the first transfer unit 11 and the discharging mechanism 210, and is configured to carry the laser welding unit 31.

In one embodiment, the scrap sealing system 100 further includes a cutting mechanism 40, and after a welding seam extending along the circumferential direction of the container 240 and being closed is formed between the sealing body 230 and the inner wall of the container 240, the cutting mechanism 40 can cut the sealing body 230 and the container 240, so as to divide the container 240 into a plurality of sections of closed accommodating chambers, each of which can store the scrap.

In the present embodiment, the cutting mechanism 40 includes the laser cutting unit 41, and the laser irradiation direction of the laser cutting unit 41 is perpendicular to the trajectory along which the joining mechanism 20 slides with respect to the second transfer unit 12. After the welding mechanism 30 welds the sealing body 230 in the container 240, the rotating and clamping unit 22 drives the container 240 to rotate relative to the laser cutting unit 41 through the clamping portion 222, so that the laser cutting unit 41 cuts the container 240 and the sealing body 230 along the circumferential direction of the container 240.

Specifically, the cutting mechanism 40 further includes a second column 42, a feed driving unit 43, a linear guide unit 44, and a slider unit 45. The second upright column 42 is fixedly provided with respect to the first transfer unit 11 and the discharging mechanism 210; the feeding driving unit 43 is mounted on the second upright post 42 for generating power for driving the laser cutting unit 41 to move relatively close to or away from the container 240, the linear guiding unit 44 is in driving connection with the feeding driving unit 43 and is in sliding fit with the slider unit 45, and the laser cutting unit 41 is mounted on the slider unit 45 in a follow-up manner.

After the feed driving unit 43 starts to operate, the slide block unit 45 can be driven to translate along the radial direction of the container 240 relative to the linear guide unit 44, so as to drive the laser cutting unit 41 to move.

It should be noted that when the sealing body 230 closes the end opening of the container 240, the sealing body 230 and the container 240 may not be cut. After the seal 230 is welded to the container 240, the sealed container 240 with the stored scrap material may be removed from the scrap encapsulation system 100. Accordingly, in other embodiments, the scrap encapsulation system 100 may not be provided with a cutting mechanism 40.

In one embodiment, the waste packaging system 100 further includes a sealing body 230 for sealing the container 240, the sealing body 230 includes a first cover and a second cover stacked together, a first air chamber is defined between the first cover and the second cover, the first air chamber stores cleaning gas, and at least one of the first cover and the second cover is hermetically connected to an inner wall of the container 240.

In this embodiment, the first cover includes a first end cap and a sleeve portion, the second cover includes a second end cap, a gap is formed between the first end cap and the second end cap, one end of the sleeve portion is connected to the first end cap, and the other end of the sleeve portion protrudes in an axial direction of the first end cap and is sleeved on an outer circumferential wall of the second cover. Therefore, the first end cover, the second end cover and the sleeve portion are arranged in a surrounding mode to form a first air chamber.

Furthermore, the first cover body further comprises an axial extension portion which is convexly arranged at one end of the first end cover, which is relatively close to one end of the second cover body, and an accommodating groove which is communicated along the circumferential direction of the sealing body is arranged between the axial extension portion and the sleeve portion.

The setting of storage tank has following beneficial effect: when the cutting mechanism 40 cuts the container 240 and the sealing body 230, the debris particles generated by the cutting can enter the containing groove, and the debris particles are prevented from being accumulated on the end surface of the first end cover facing the second cover body, so that the flatness and the cleanliness of the end surface of the first end cover facing the second cover body are ensured. In this way, the external suction device, for example, the sealing body transfer mechanism for sucking the sealing body 230, can be more reliably sucked to the end surface of the first end cap facing the second cover body by the suction of the suction cup, so that the first end cap together with the container 240 welded and sealed with the first end cap is sucked and removed from the transfer mechanism 10, thereby preventing the first end cap together with the container welded with the first end cap from falling down due to the formation of an air gap when the sealing body transfer mechanism sucks the first end cap and the damage of the vacuum degree between the suction cup and the first end cap.

The welding mechanism 30 is used to form at least two welding seams between the sealing body 230 and the inner wall of the container 240 along the axial direction of the container 240, the welding seams are divided into two groups, at least one welding seam is formed in each group, one group is formed between the first cover body and the inner wall of the container 240, and the other group is formed between the second cover body and the inner wall of the container 240.

Therefore, when the welding is completed, the sealing body 230 divides the cavity of the container 240 into two isolated chambers.

After welding is complete, the cutting mechanism 40 is able to cut the container 240 and the seal body 230 at the cutting location. Wherein the cutting location is located between the weld that sealingly connects the container 240 to the first cover and the weld that sealingly connects the container 240 to the second cover, and the axial height of the cutting location is within the axial dimension of the first plenum.

Therefore, after the cutting, although the first air chamber is cut, the cut sealing body 230 can still seal the two accommodating chambers respectively, so that the two accommodating chambers in the container 240 are still isolated from each other, and the air in the inner cavity of the container 240 or the air in the inner cavity of the waste bin 250 cannot escape outwards to pollute the external clean environment.

Furthermore, a first axial flange is formed on the axial extension part and protrudes towards the second cover body, and the first axial flange is of an annular closed structure; the second end cover is outwards convexly arranged at one side which is relatively far away from the first end cover to form a second axial flange, and the second axial flange is of an annular closed structure. The first axial flange and the second axial flange are the same in height, the inner diameters of the first axial flange and the second axial flange are the same in size, and the outer diameters of the first axial flange and the second axial flange are the same in size.

With such an arrangement, the waste packaging system 100 can be connected to the second end cap where the second axial flange is located and the axial extension where the first axial flange is located in sequence by using the same sealing body transfer mechanism. After the cutting mechanism 40 finishes cutting the sealed body 230 and the container 240, the sealed body transfer mechanism may sequentially pass two pieces of containers through the discharge opening 201 and remove the two pieces of containers from the transfer mechanism 10.

In one embodiment, the waste packaging system 100 further includes a centering mechanism 50 slidably mounted to the lift rail 121 on a side of the engagement mechanism 20 relatively adjacent to the discharge mechanism 210. The righting mechanism 50 is drivingly connected to an external drive source, and under the drive of the external drive source, the righting mechanism 50 moves along the lifting rail 121 while being in sliding contact with the container 240. During movement of centering mechanism 50 toward discharge mechanism 210, the angular and distance deviations between the axis of container 240 and the axis of discharge opening 201 decrease until the axes coincide, eventually aligning the opening of container 240 with discharge opening 201 and the two engage smoothly.

It should be noted that the axis of the container 240 and the axis of the discharge opening 201 are coincident, but not necessarily completely coincident, and there may be a certain angle deviation or distance deviation therebetween, as long as the righting mechanism 50 can ensure that the container 240 and the discharge opening 201 are successfully connected, and the discharge mechanism 210 and the container 240 are reliably joined and form a good sealing fit.

In this embodiment, the righting mechanism 50 includes a second lifting unit 52 slidably engaged with the lifting rail 121, a righting adjusting unit 53 movably mounted on the second lifting unit 52, and a righting guide unit 51 penetrating the righting adjusting unit 53. Wherein, the righting guide unit 51 is provided with a righting guide hole for sleeving the container 240, and is used for forming sliding fit between the inner wall of the righting guide hole and the outer peripheral wall of the container 240. The centering guide hole is provided opposite to the rotary clamp unit 22 in the extending direction of the lifting rail 121.

Further, the centering mechanism 50 and the engaging mechanism 20 are respectively in driving connection with two sets of external driving sources, and the two sets of external driving sources respectively and independently drive the centering mechanism 50 and the engaging mechanism 20 to slide, so that the distance between the centering mechanism 50 and the engaging mechanism 20 is adjustable.

Specifically, the second transfer unit 12 further includes a fourth transmission shaft 123 parallel to the elevation guide 121, a screw transmission portion is provided on an outer peripheral portion of the fourth transmission shaft 123, and the second elevation unit 52 is slidably engaged with the elevation guide 121 and screw-engaged with the fourth transmission shaft 123, so that the second elevation unit 52 and the fourth transmission shaft 123 can relatively screw-move.

The first transfer unit 11 further comprises a fifth transmission shaft 114, one end of the fifth transmission shaft 114 is formed or provided with a third power input end 73 for driving connection with an external driving source; the fifth transmission shaft 114 is further provided with a second driving gear 1141, one end of the fourth transmission shaft 123 extends toward the first transfer unit 11 and is provided with a second driven gear 1231, and the second driving gear 1141 is engaged with the second driven gear 1231.

Under the driving of the external driving source, the fifth transmission shaft 114 drives the fourth transmission shaft 123 to rotate through a gear engagement manner, the fourth transmission shaft 123 moves spirally relative to the second lifting unit 52, the lifting guide rail 121 limits the second lifting unit 52 from rotating relative to the second transferring unit 12, and allows the second lifting unit 52 to translate along the lifting guide rail 121. This realizes that the second transfer unit 12 guides the centering mechanism 50 to slide along the elevation rail 121.

Preferably, in this embodiment, the second lifting unit 52 is in threaded engagement with the fourth transmission shaft 123. Of course, in other embodiments, the transmission may be implemented by means of a ball screw.

In the present embodiment, the first power input end 71, the second power input end 72, and the third power input end 73 extend from the same end of the first transfer unit 11, and the first transmission shaft 112, the third transmission shaft 113, and the fifth transmission shaft 114 are arranged in parallel with each other, and the second transmission shaft 122 is arranged in parallel with the fourth transmission shaft 123. So configured, the arrangement of the various actuators within the waste packaging system 100 is compact.

A gap is arranged between the centralizing guide unit 51 and the centralizing adjusting unit 53, so that a movement margin is formed between the centralizing guide unit 51 and the centralizing adjusting unit 53, and the centralizing adjusting unit 53 can drive the centralizing guide unit 51 to move along the radial direction within the limited range of the movement margin while moving relative to the second lifting unit 52.

The effect of so setting up is that, the position accuracy of the guide unit 51 of righting adjusts more easily, can drive the guide unit 51 of righting for second lifting unit 52 micro-motion through the mode of adjusting the regulation unit 53 of righting to guarantee the axiality of container 240 and bin outlet 201, eliminate because of the waste material packaging system 100 long-term operation causes the position deviation of the guide unit 51 of righting.

Further, in this embodiment, a rolling body is further disposed between the centering guide unit 51 and the centering adjustment unit 53, and the rolling body is in rolling contact with an outer wall of the centering guide unit 51 and an inner wall of the centering adjustment unit 53, respectively.

The rolling element can be rolling bearing.

In one embodiment, the discharging mechanism 210 is fixedly disposed with respect to the first transfer unit 11. The discharging mechanism 210 comprises a flange plate which is arranged on one side of the waste bin 250 facing the ground and provided with a middle through hole, and further comprises a sealing unit which is rotatably arranged in the middle through hole, and the discharging opening 201 is arranged in the sealing unit. The sealing unit can rotate relative to the first transferring mechanism 10, and is used for sleeving the container 240 and sealing and matching with the container 240.

After the container 240 is communicated with the discharge opening 201, the rotating and clamping unit 22 can drive the container 240 to rotate relative to the discharge mechanism 210, and the sealing unit is sleeved on the container 240 and can rotate relative to the flange plate and the waste bin 250 along with the container 240, so that a rotary seal is formed between the container 240 and the sealing unit.

So configured, the air tightness of the waste bin 250 and the container 240 can be further ensured, preventing the waste material from polluting the external environment gas.

In one embodiment, the waste packaging system 100 further includes a sealing body transfer mechanism including a transfer module movable relative to the discharge mechanism 210, the transfer module being configured to transfer the sealing body 230 and being capable of moving the sealing body 230 into the container 240 through the discharge opening 201.

Preferably, in this embodiment, the transferring module is connected to the pneumatic control system and includes an absorbing element. The transfer module can carry the sealing body 230 in an adsorption mode and transfer the sealing body 230 into the container 240; after the sealing body 230 and the container 240 are welded and sealed, the transfer module can again suck the sealing body 230 by the suction member, thereby removing the container 240 storing the scrap from the transfer mechanism 10.

In this embodiment, after the sealing body 230 and the inner wall of the container 240 are welded and sealed, the transferring module can be attached to one end of the sealing body 230, and the container 240 is driven to pass through the discharging opening 201 along the vertical direction to move out of the transferring mechanism 10.

With such an arrangement, the waste packaging system 100 realizes unmanned and automatic operations of pre-loading the sealing body 230 into the container 240 and removing the container 240 from the transfer mechanism 10 by providing the sealing body transfer mechanism, thereby further reducing human involvement and lowering operation cost.

According to the waste packaging system 100 provided by the invention, after the container 240 is communicated with the discharge opening 201, waste can be loaded into the inner cavity of the container 240 under the condition that the inner cavity of the container 240 is separated from the external environment, so that the condition that the waste is exposed is avoided, and the waste can be prevented from polluting air or harming human health; the sealing body 230 is used for sealing and closing the inner cavity of the container 240, so that the sealing body 230 can form good shielding and isolation between the inner cavity of the container 240 and the external environment, air flow between the inner cavity of the container 240 and the external environment is inhibited, and sealing safety of waste storage is further improved.

Specifically, the first preset position and the second preset position correspond to two limit positions of a trajectory formed by the transfer mechanism 10 sliding on the transfer mechanism 10, respectively.

In step S1, the engagement mechanism 20 sliding forward means that the engagement mechanism 20 moves from the first preset position to approach the second preset position; in step S2, the arrangement of the joining mechanism 20 opposite to the discharging mechanism 210 means that when the joining mechanism 20 is provided with the container 240 and is located at the first preset position, the axis of the container 240 is coincident with the axis of the discharging opening 201 of the discharging mechanism 210, and the opening of the container 240 is circumferentially opposite to the discharging opening 201.

In one embodiment, the transfer mechanism 10 includes a lifting rail 121, and the joining mechanism 20 includes a first lifting unit 21 slidably mounted on the lifting rail 121, and a rotating clamping unit 22 mounted on the first lifting unit 21 in a follow-up manner.

After step S4, the method further includes the following steps:

s41, the rotating clamping unit 22 rotates the container 240 relative to the transfer mechanism 10, so that the laser welding unit 31 rotates relative to the container 240, and a weld seam extending and closing along the circumferential direction of the container 240 is formed between the sealing body 230 and the container 240.

In step S31, the first lifting unit 21 drives the rotating holding unit 22 and the container 240 to move synchronously along the length direction of the lifting guide rail 121; in step S41, the rotating clamp unit 22 achieves the effect that the laser welding unit 31 moves relative to the container 240 in the circumferential direction of the container 240, so that the angle of the laser welding unit 31 relative to the container 240 is automatically adjusted and changed, and therefore, the seal welding between the inner wall of the container 240 and the seal body 230 can be automatically completed without a person manually rotating the container 240 or the laser cutting unit 41.

In one embodiment, the sealing body 230 includes a first cover body and a second cover body stacked together, and the step S5 of sealing and welding the sealing body 230 to the inner cavity of the container 240 by the welding mechanism 30 includes the following steps:

s51, the welding mechanism 30 is used for forming at least two welding seams between the sealing body 230 and the inner wall of the container 240 along the axial direction of the container 240, at least one welding seam connects the container 240 with the first cover body in a sealing manner, and at least one welding seam connects the container 240 with the second cover body in a sealing manner.

As can be seen from the foregoing, the sealing body 230 divides the inner cavity of the container 240 into two chambers at two ends thereof. After the welding is finished, the two accommodating chambers are isolated from each other, and each accommodating chamber is isolated from the external environment. Thus, a hermetic closure of the container 240 is achieved.

Further, a first air chamber is defined between the first cover and the second cover, the scrap encapsulating system 100 further includes a cutting mechanism 40, and in step S51, the welding mechanism 30 is configured to form at least two welding seams between the sealing body 230 and the inner wall of the container 240 along the axial direction of the container 240, at least one welding seam sealingly connects the container 240 with the first cover, and at least one welding seam sealingly connects the container 240 with the second cover, the method includes the following steps:

s511, the cutting mechanism 40 cuts the container 240 and the sealing body 230 at a cutting position, the cutting position is located between the welding seam for sealing and connecting the container 240 and the first cover body and the welding seam for sealing and connecting the container 240 and the second cover body, and the axial height of the cutting position is located within the axial size range of the first air chamber.

So set up, select cutting position cutting container 240 and seal 230 back in the axial dimensions within range of first air chamber, two accommodation chambers still can be sealed respectively by the seal of cutting, can not cause the gaseous further outside loss that is polluted by the waste material in the container, perhaps the inside gaseous outside loss that is polluted by the waste material of dump bin 250.

The waste packaging method provided by the invention can reduce or eliminate the risk that the waste pollutes the air or harms the human health, and realizes the automation and the unmanned operation of the sealing body 230 for sealing the inner cavity of the container 240; the sealing body 230 is welded in the container 240 by the welding mechanism 30, so that the inner cavity of the container 240 and the external environment are well shielded and isolated, and the sealing safety of waste storage is improved.
