It should be noted that, since the filter forming unit 210 in the net frame 200 is used for depositing the ecological plant fiber and finally forming the deposited ecological plant fiber into a wet blank in the filter forming unit 210, and the wet blank in the filter forming unit 210 is processed into a dry blank, the net frame 200 is further vacuum sucked by the first vacuum suction head 22 and the second vacuum suction head 23, and accordingly, the sucked position of the net frame 200 is preferably a flat and airtight structure.

As shown in fig. 7 to 10, the lifting mechanism 36 includes a lifting frame 361 and a lifting motor 362 for driving the lifting frame 361 to move up and down along the wet blank frame 31. The lifting motor 362 is assembled on the wet blank frame 31, and the wet blank frame 31 provides a supporting function and an assembling place for the lifting motor 362; the lower slurry fishing die 35 is assembled on the lifting frame 361, the lifting frame 361 provides a supporting function and an assembling place for the lower slurry fishing die 35, and the lower slurry fishing die 35 can lift along with the lifting frame 361; therefore, under the driving of the lifting motor 362 to the lifting frame 361, the lifting frame 361 drives the lower slurry salvaging mold 35 to lift to any position, so that the lower slurry salvaging mold 35 can sequentially lift upwards to the position of the screen frame 200 with the wet blank sucked by the second vacuum suction head 23 and the position of contacting with the empty screen frame 200 supported by the screen frame supporting mechanism 33, and the lower slurry salvaging mold 35 can also descend downwards to sink into the slurry tank 34 after receiving the empty screen frame 200. Specifically, the lifting frame 361 comprises a bottom plate 3611 positioned right below the wet blank upper die 32, an upper and lower rod 3612 positioned beside the wet blank upper die 32 and a transverse frame 3613 positioned above the wet blank upper die 32; the upper and lower rods 3612 are respectively arranged beside two opposite sides of the wet blank upper die 32, the upper and lower rods 3612 penetrate through the wet blank rack 31 along the up-down direction of the wet blank rack 31, and the bottom plate 3611 is fixedly connected with the upper and lower rods 3612; the transverse frame 3613 is positioned right above the lifting motor 362, and the transverse frame 3613 is fixedly connected with the upper and lower rods 3612, so that the lifting frame 361 is in a shape of a Chinese character 'Ruo' and surrounds the lifting motor 362 and the upper wet blank die 32 from the periphery, and the arrangement is more compact; the output end of the lifting motor 362 is fixedly connected with an upper and lower screw rod 363, an upper and lower screw nut 364 is fixed on the transverse frame 3613, the upper and lower screw nut 364 is sleeved on the upper and lower screw rod 363, and the upper and lower screw rod 363 is positioned right above the lifting motor 362. By means of the upper and lower rods 3612, the bottom plate 3611 and the transverse frame 3613, the arrangement between the lifting frame 361 and the wet blank upper die 32 and the slurry fishing lower die 35 is more compact and reasonable, the force application position of the lifting motor 362 to the lifting frame 361 is more reasonable, and in addition, by means of the matching of the upper and lower screw rods 363 and the upper and lower screw nuts 364, the lifting motor 362 can more accurately control the lifting frame 361 and the slurry fishing lower die 35 on the lifting frame 361 to do more accurate lifting movement. It can be understood that, according to the actual requirement, the lifting motor 3612 can drive the lifting frame 361 to lift by adopting the matching of the upper and lower screw rods 363 and the upper and lower screw nuts 364, and can also drive the lifting frame 361 to lift by adopting belt transmission, chain transmission or gear transmission, wherein, for the belt transmission, two belt wheels which are positioned beside the wet blank upper die 32 and are arranged in a pair one above the other and a belt sleeved on the two belt wheels are arranged on the wet blank frame 21, and then one side of the belt is fixedly connected with the lifting frame 361; for chain transmission, two chain wheels which are positioned beside the wet blank upper die 32 and are arranged in a pair of up and down and a chain sleeved on the two chain wheels are arranged on the wet blank frame 21, and one side of the chain is fixedly connected with the lifting frame 361; for the gear transmission, an upper spur rack and a lower spur rack which are positioned beside the upper wet blank die 32 are fixed on the upper rod 363 and the lower rod 363, and a gear which is in meshing transmission with the upper spur rack and the lower spur rack is fixed at the output end of the lifting motor 362; the above manner can achieve the purpose that the lifting motor 362 drives the lifting frame 361 to lift to any position.

As shown in fig. 7 to 10, the frame holding mechanisms 33 are respectively disposed beside opposite sides of the wet blank upper die 32, so as to increase the reliability of holding the frame 200; the frame supporting mechanism 33 comprises a rotary driver 331 and a supporting block 332 mounted at the output end of the rotary driver 331, the rotary driver 331 is switched to the supporting position by driving the supporting block 332 to rotate to the position right below the wet blank upper die 32, and the rotary driver 331 is switched to the avoiding position by driving the supporting block 332 to rotate away from the position right below the wet blank upper die 32; so that the gap between the frame holding mechanism 33 and the wet blank upper die 32 can be made more compact by the rotary driver 331 and the holding block 332. For example, the rotation driver 331 can be a rotary cylinder, or a rotary motor, but not limited thereto. Note that, according to actual needs, a modification of the frame supporting mechanism 33 is: the screen frame supporting mechanism comprises a telescopic driver which does telescopic motion along the horizontal direction, the telescopic driver is switched to a supporting position by extending to the position right below the wet blank upper die 32, and the telescopic driver is switched to an avoiding position by retracting to the position right below the wet blank upper die 32, so that the purpose of supporting or releasing the screen frame 200 by the screen frame supporting mechanism is achieved; the telescopic actuator may be a telescopic cylinder or a telescopic oil cylinder, but not limited thereto.

To sum up and in conjunction with fig. 1, the method for transferring a web of paper mold tape of the present invention comprises the steps of:

and S001, driving the Y-axis transfer modules 13 on the left side and the right side to perform XZ-axis translation on the portal frame 11 together with the screen frame feeding and discharging mechanism 20 by the XZ-axis transfer module 12 until the screen frame feeding and discharging mechanism 20 is aligned with the wet blank forming machine 30 along the Y-axis direction, so as to prepare for extending the screen frame feeding and discharging mechanism 20 into the wet blank forming machine 30 after the mold is opened along the Y-axis direction.

S002, the Y-axis transfer modules 13 on the left and right sides synchronously drive the frame loading and unloading mechanism 20 to extend into the wet blank forming machine 30 after the mold opening, and the frame holding mechanism 33 in the holding position in the wet blank forming machine 30 holds the empty frame 200 sucked by the first vacuum suction head 22 in the frame loading and unloading mechanism 20 from below, as shown in fig. 7.

S003, the XZ-axis transfer module 12 drives the Y-axis transfer module 13 on the left side and the Y-axis transfer module 13 on the right side to move downwards along the Z-axis direction together with the screen frame loading and unloading mechanism 20, so that the second vacuum suction head 23 in the screen frame loading and unloading mechanism 20 sucks away the screen frame 200 with wet blanks on the paddle scooping lower die 35, and meanwhile, the first vacuum suction head 22 in the screen frame loading and unloading mechanism 20 is moved away from the empty screen frame 200 supported by the screen frame supporting mechanism 33; specifically, before step S003, the slurry fishing lower die 35 is driven by the lifting mechanism 36 in the wet blank forming machine 30 to be matched with the wet blank upper die 32 in the wet blank forming machine 30, so that the wet blank in the mesh frame 200 with the wet blank on the slurry fishing lower die 35 is formed by the slurry fishing lower die 35 and the wet blank upper die 32 together and excess slurry is squeezed out, thereby creating a good condition for transferring the subsequent wet blank to a dry blank; then, the lifting mechanism 36 drives the lower slurry dragging mold 35 and the wet blank frame 200 on the lower slurry dragging mold 35 to descend to a position where the second vacuum suction head 23 sucks the wet blank frame 200, but not limited thereto.

And S004, the Y-axis transfer modules 13 on the left side and the right side synchronously drive the screen frame loading and unloading mechanism 20 to move away from the wet blank forming machine 30 after the mold opening, and the XZ-axis transfer module 12 drives the Y-axis transfer modules 13 on the left side and the right side together with the screen frame loading and unloading mechanism 20 to move to the position aligned with the dry blank forming machine 40 after the mold opening.

S005, the Y-axis transfer modules 13 on the left side and the right side synchronously drive the screen frame feeding and discharging mechanism 20 to extend into the dry blank forming machine 40 after the mold opening along the Y-axis direction, the XZ-axis transfer module 12 drives the screen frame feeding and discharging mechanism 20 to translate along the Z-axis direction, so that the second vacuum suction head 23 in the screen frame feeding and discharging mechanism 20 transfers the screen frame 200 with the wet blank into the dry blank forming machine 40 after the mold opening, and the first vacuum suction head 22 in the screen frame feeding and discharging mechanism 20 sucks the screen frame 200 with the dry blank at the position of the dry blank forming machine 40; specifically, in step S005, the upper dry blank mold 41 leaves the screen frame 200 with the dry blank on the upper dry blank mold 41 through vacuum adsorption during the mold opening process of the dry blank molding machine 40, and correspondingly, the screen frame loading and unloading mechanism 20 extending into the opened dry blank molding machine 40 performs a translation of first descending and then ascending under the driving of the XZ-axis transfer module 12, so that the second vacuum suction head 23 transfers the sucked screen frame 200 with the wet blank to the lower dry blank mold 42 of the opened dry blank molding machine 40, and the first vacuum suction head 22 sucks the screen frame 200 with the dry blank left on the upper dry blank mold 41 after mold opening, thereby improving the speed and efficiency of loading and unloading the screen frame loading and unloading mechanism 20 on the screen frame 200 at the dry blank molding machine 40. And

s006, the Y-axis transfer modules 12 on the left and right sides synchronously drive the screen frame loading and unloading mechanism 20 to move away from the dry blank forming machine 40 after the mould opening, the XZ-axis transfer module 12 drives the Y-axis transfer modules 13 on the left and right sides and the screen frame loading and unloading mechanism 20 to move to the dry blank unloading position together, so that the dry blanks in the screen frame 200 with the dry blanks sucked by the first vacuum suction head 22 are all taken away, and one cycle of screen frame 200 transfer is completed. It should be noted that the dry blanks in the frame 200 sucked by the first vacuum head 22 can be removed by an external material-taking robot or a material-taking robot. More specifically, the following:

in step S003, when the second vacuum suction head 23 sucks the mesh frame 200 with the wet blank and the first vacuum suction head 22 moves away from the empty mesh frame 200 supported by the mesh frame supporting mechanism 33, the XZ-axis transfer module 12 and the Y-axis transfer module 13 drive the mesh frame loading and unloading mechanism 20 to translate toward the dry blank forming machine 40, and during the translation toward the dry blank forming machine 40, the lifting mechanism 36 in the wet blank forming machine 30 lifts the slurry fishing lower mold 35 to a position where the slurry fishing lower mold is in contact with the empty mesh frame 200 supported by the mesh frame supporting mechanism 33, and the mesh frame supporting mechanism 33 places the supported empty mesh frame 200 on the slurry fishing lower mold 35; then, the lifting mechanism 36 drives the lower bailing mold 35 and the empty net frame 200 on the lower bailing mold 35 to move downward and sink into the slurry tank 34 of the wet blank forming machine 30, so as to meet the requirement that the wet blank is redeposited on the empty net frame 200 on the lower bailing mold 35, but the description is not limited thereto.

In steps S002, S004, S005 and S006, the Y-axis motor 131 in the left Y-axis transfer module 13 drives the left winding return member 132 to rotate around the left first rotating wheel 133 and the left second rotating wheel 134, and the Y-axis motor 131 in the right Y-axis transfer module 13 drives the right winding return member 132 to rotate around the right first rotating wheel 133 and the right second rotating wheel 134, and under the action of the synchronizing shaft 135 that fixes the left and right first rotating wheels 133 together, the left and right winding return members 132 synchronously drive the frame loading and unloading mechanism 20 to translate along the Y-axis direction, so as to effectively ensure the smoothness of the telescopic translation of the frame loading and unloading mechanism 20 along the Y-axis direction, and avoid the problem that the frame loading and unloading mechanism 20 is stuck due to asynchronous left and right stretching. Specifically, in the process of the rotation of the left and right first pulleys 133, the fast one drives the slow one through the synchronizing shaft 135, thereby achieving the synchronization of the rotation of the left and right first pulleys 133.

Wherein, the first vacuum suction head 22 and the second vacuum suction head 23 respectively suck the screen frame 200 from the periphery of the screen frame 200, the first vacuum suction head 22 is used for sucking the screen frame 200 upwards, and the second vacuum suction head 23 is used for sucking the screen frame 200 downwards, so that the arrangement aims at improving the speed and the efficiency of the feeding and discharging transfer of the screen frame 200. Meanwhile, the XZ-axis transfer module 12 drives the Y-axis transfer modules 13 on the left and right sides and the frame loading and unloading mechanism 20 to perform XZ-axis translation on the portal frame 11 through the matching of the motor, the gear and the linear rack, so as to ensure the accurate reliability of the transfer of the frame 200; in addition, the Y-axis transfer modules 13 on the left and right sides drive the left and right sides of the frame loading and unloading mechanism 20 to synchronously extend and translate through the constraint of a synchronization shaft 135.

Compared with the prior art, by means of the matching of the steps S001 to S006, the paper mould belt net transfer method provided by the invention has the advantages that the feeding and discharging transfer of the net frame 200 is carried out in a net frame 200 sucking mode, a profiling jig is not needed for carrying out vacuum adsorption on wet blanks or dry blanks, and the waste of an air source is reduced; the telescopic translation of the screen frame feeding and discharging mechanism 20 along the Y-axis direction is synchronously driven by the Y-axis transfer module 13 beside the left side and the right side, so that the problem that the screen frame feeding and discharging mechanism 20 is unsynchronized in sliding and blocked due to the left side and the right side is avoided, and the bearing capacity of the Y-axis transfer module 13 on the screen frame feeding and discharging mechanism 20 is increased, so that the smooth reliability of feeding and discharging transfer of the screen frame 20 can be ensured under the condition of reducing air source waste. In addition, the gantry robot 10 is respectively matched with the wet blank forming machine 30 and the dry blank forming machine 40 so as to be adapted to a narrow space.

It should be noted that, in fig. 2 and 3, the positive direction of the X axis is the left-to-right direction of the gantry 11, the positive direction of the Y axis is the front-to-back direction of the gantry 11, and the positive direction of the Z axis is the bottom-to-top direction of the gantry 11. The specific structure and operation principle of the dry blank forming machine 40 are well known in the art, and the gantry robot 10, the wet blank forming machine 30 and the dry blank forming machine 40 are respectively installed outside, such as on the ground, and therefore, the detailed description thereof is omitted.
