Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

As shown in fig. 1 to 3, the welding cloth device 1 according to the embodiment of the present invention includes an upper sealing blade 11 and a lower sealing blade 12.

The lower sealing knife 12 and the upper sealing knife 11 are arranged at intervals in the up-down direction, and the lower sealing knife 12 and the upper sealing knife 11 can approach and separate from each other in the up-down direction.

Wherein the lower sealing blade 12 includes a base 121, a first sealing element group and a second sealing element group.

The base 121 and the upper seal blade 11 are spaced from each other in the vertical direction and are disposed opposite to each other.

The first sealing element group and the second sealing element group are arranged on the base 121, and the first sealing element group and/or the second sealing element group can move along the up-down direction.

Specifically, the upper and lower seal blades 11 and 12 are spaced apart from and opposite to each other in the up-down direction as shown in fig. 1, and the upper and lower seal blades 11 and 12 can be moved toward and away from each other in the up-down direction, and when the upper and lower seal blades 11 and 12 are moved toward and in contact with each other, the material between the upper and lower seal blades 11 and 12 can be sealed by the upper and lower seal blades 11 and 12. In some other embodiments, the material between the upper sealing knife 11 and the lower sealing knife 12 can be sealed by moving one of the upper sealing knife 11 and the lower sealing knife 12 in the up-and-down direction.

As shown in fig. 1, the lower sealing blade 12 further includes a base 121, and a first sealing component and a second sealing component are disposed on the base 121, through which different regions of the material between the upper sealing blade 11 and the lower sealing blade 12 can be sealed.

Each of the first and second seal assemblies is movable in an up-and-down direction as shown in fig. 1. When the first sealing component moves upwards and the height in the vertical direction is greater than that of the second sealing component, and when the upper sealing knife 11 and the lower sealing knife 12 approach each other to seal the material, the height of the first sealing component in the vertical direction is greater than that of the second sealing component in the vertical direction, so that the first sealing component contacts with the upper sealing knife 11 during sealing, and the first sealing process is completed.

Similarly, when the height of the second sealing component in the up-down direction is greater than the height of the first sealing component in the up-down direction, the second sealing component contacts the upper sealing knife 11 during sealing, and the second sealing process is completed. The materials can be sealed and welded by adjusting the heights of the first sealing and welding group and the second sealing and welding assembly in the up-down direction. For example, when the bagged spring is sealed, the bagged spring needs to be sealed in the horizontal direction (the left and right direction shown in fig. 1) and the vertical direction (the front and back direction shown in fig. 1) respectively, so that the bagged spring can be sealed in the horizontal direction by using the first sealing and welding set, and the bagged spring can be sealed in the vertical direction by using the second sealing and welding assembly, and the sealing and welding work of the bagged spring is completed. It can be understood that vertical sealing can be carried out through the first sealing assembly, and horizontal sealing is carried out through the second sealing assembly, so that the sealing efficiency is improved, and the production cost is reduced. The height of the first sealing component group and the second sealing component in the vertical direction can be adjusted through driving devices, such as a motor, a pneumatic cylinder, a hydraulic cylinder and the like, and can also be manually operated. It is also possible that only one of the first and second seal members is movable in the up-down direction to adjust the relative height of the first and second seal members in the up-down direction to control the object (the first seal member or the second seal member) in contact with the upper sealing blade 11.

Therefore, the cloth welding device has the advantages of low production cost and high sealing efficiency.

In some embodiments, the first and second seal assemblies can be sealed simultaneously.

Wherein, first seal welding group and second seal welding subassembly can seal welding simultaneously and mean: when the welding cloth device 1 is in operation, the second sealing assembly may or may not work simultaneously with the first sealing assembly.

Specifically, when the weld formed by the first sealing component group contacting the upper sealing knife 11 and the weld formed by the second sealing component contacting the upper sealing knife 11 are juxtaposed in the left-right direction, the first sealing component group and the second sealing component are simultaneously sealed.

Therefore, when the second sealing assembly is used for sealing the same material, the second sealing assembly can be in a continuous working state, and the height of the first sealing assembly in the up-down direction can be adjusted only when vertical sealing is needed (the height of the first sealing assembly and the height of the second sealing assembly in the up-down direction are the same). Thereby improving the production efficiency.

The following is specifically described by taking fig. 4 as an example:

as shown in fig. 4, the first sealing component group is used for performing vertical sealing, the second sealing component is used for performing horizontal sealing, and on the first, seventh, thirteenth and other horizontal welding seams 7 from left to right, the vertical welding seam 8 is adjacent to the horizontal welding seam 7 in the left-right direction, and then the first sealing component group and the second sealing component perform sealing simultaneously.

As shown in fig. 1, the first solder seal group includes a plurality of first solder seals. Each first seal includes at least one first seal tooth 122 therein, and the first seal tooth 122 extends in the left-right direction.

The second seal welding assembly comprises a plurality of second welding line groups, the second welding line groups and the first seal welding pieces are arranged in the left and right directions at intervals, and the second seal welding groups are located on two sides of the first seal welding pieces in the left and right directions. Each second sealing group comprises at least one second sealing tooth 123, and the second sealing teeth 123 extend in the front-back direction.

According to the cloth welding device provided by the embodiment of the invention, the first sealing teeth 122 extend along the left-right direction, so that the length of the transverse welding seam 7 can be increased when the material is sealed and welded transversely (in the left-right direction) through the first sealing and welding part group, the using number of the first sealing teeth 122 can be reduced, and the processing difficulty and time can be reduced. Similarly, second seal tooth 123 extends along the fore-and-aft direction, can increase vertical welding seam 8's length when sealing weld the material vertically (fore-and-aft direction) through the second sealing weld subassembly, and then can reduce the use quantity of second seal tooth 123, reduces the processing degree of difficulty and time.

Meanwhile, the second seal welding groups and the first seal welding pieces are alternately arranged at intervals and are positioned on two sides of the first seal welding pieces, so that the materials can be sealed and welded to form a plurality of independent spaces with the same size in the seal welding process. It will be appreciated that when the pocketed springs are sealed, each of the pocketed springs may be individually positioned in a separate space to form a string of pocketed springs.

Wherein the first transport element 21 and the second transport element 22 comprise conveyor belts.

Or, one of the first conveying member 21 and the second conveying member is a pressing plate, the other one of the first conveying member 21 and the second conveying member 22 is a conveying belt, a magnetic base for adsorbing the spring is arranged on the conveying belt, and when the spring is conveyed to a designated position through the conveying belt, the pressing plate moves towards the direction of the neighboring conveying belt to compress the spring.
