Description

Technical Field

[0001] This utility model relates to the technical field of leather processing equipment, and in particular to a PVC leather punching and cutting device. Background Technology

[0002] Medical air cushions are cushions that can be inflated with air. When placed under pressure points on bedridden patients, they can relieve pressure, prevent pressure sores, promote blood circulation, reduce pain, and promote sleep.

[0003] Medical air cushions are typically made from PVC sheet material, which is fed, punched, and cut into sheets of a specific size. These sheets are then double-layered, heat-fused, and slit. For example... Figures 1 to 2 As shown, in order to speed up production efficiency, multiple air nozzle holes 103 are usually punched on the same PVC material 101. When hot melting is performed later, a layer of PVC material 101 with air nozzle holes 103 is stacked on another layer of PVC material 101 without air nozzle holes 103, and then hot melting is performed. After hot melting is completed, it is then cut.

[0004] In the existing technology, the PVC sheet 101 is usually unrolled to a certain length and then stretched to a cutting device for cutting into sections. Because the PVC sheet 101 is smooth, it is usually put into the cutting device by manual pulling, which is inefficient and the flatness of the PVC sheet 101 is difficult to guarantee. After cutting, the PVC sheet 101 is transferred to a punching device for punching. The whole process requires two machines, which is costly and inefficient.

[0005] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a PVC leather punching and cutting device to solve the problems of high cost and low efficiency caused by the need for manual pulling and feeding and the need for multiple machines in the production of PVC leather.

[0009] An adjustment mechanism is provided on one side of the conveying mechanism along the x-direction, and at least two such mechanisms are provided. The distance between two adjacent adjustment mechanisms is adjustable. Each adjustment mechanism includes a base plate whose position can be adjusted along the x-direction.

[0010] A punching mechanism, fixed to the upper end of the base plate, is used to punch air nozzle holes in the PVC material;

Each rolling conveying component includes a first circular roller extending along the y-direction, a second circular roller extending along the y-direction, and a plurality of spring ropes sleeved on the outside of the first and second circular rollers and spaced apart along the y-direction. A first conveying channel is formed between the upper and lower rows of spring ropes, and the PVC leather material passes through the first conveying channel along the x-direction.

[0012] Specifically, the diameter of the first roller is smaller than the diameter of the second roller, and a rotation drive device is fixed on the first bracket. The output shaft of the rotation drive device is connected to the first roller in a transmission connection.

[0013] Specifically, the conveying mechanism includes two columns fixed to the upper end of the operating table and arranged along the y-direction, an upper conveying roller and a lower conveying roller rotatably disposed between the two columns, and a second conveying channel for the PVC material to pass through is formed between the upper conveying roller and the lower conveying roller.

[0020] Specifically, the operating table is also equipped with an inclined pusher plate, which is located on one side of the cutting mechanism along the x-direction, and the pusher plate is also equipped with a baffle.

[0021] The beneficial effects of this utility model are:

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] Please refer to Figure 1 and Figures 3-7 This embodiment of a PVC leather punching and cutting device includes:

[0034] The control panel 40 is equipped with a conveying mechanism 90 that conveys PVC leather 101 along the x-direction;

[0035] Adjustment mechanism 42 is provided on one side of the conveying mechanism 90 along the x direction. At least two adjustment mechanisms 42 are provided. The distance between two adjacent adjustment mechanisms 42 is adjustable. The adjustment mechanism 42 includes a base plate 424 whose position can be adjusted along the x direction.

[0036] The punching mechanism 50 is fixed to the upper end of the base plate 424 and is used to punch air nozzle holes 103 into the PVC leather 101.

[0037] The cutting mechanism 70 is located on the other side of the conveying mechanism 90 along the x-direction. It includes a first bracket 71 fixed to the upper end of the operating table 40, a leather material transfer module 72 and a leather material cutting module 73 on the first bracket 71. The leather material transfer module 72 includes two sets of rolling conveying components with adjustable vertical spacing. The rolling conveying components include a first circular roller 721 extending along the y-direction, a second circular roller 722 extending along the y-direction, and a plurality of spring ropes 723 sleeved on the outside of the first circular roller 721 and the second circular roller 722 and spaced apart along the y-direction. A first conveying channel is formed between the upper and lower rows of spring ropes 723. The PVC leather material 101 passes through the first conveying channel along the x-direction.

[0038] The PVC leather punching and cutting device of this embodiment can be used for the production and processing of medical air cushions. The roll of PVC leather 101 is loaded onto the feeding roller (not shown) on one side of the operating table 40, and then the PVC leather 101 is released along the x direction. When the PVC leather 101 is conveyed to the punching mechanism 50, the punching mechanism 50 punches air nozzle holes 103 into the PVC leather 101. Then, through the conveying mechanism 90, the PVC leather 101 is guided into the leather transfer module 72 of the cutting mechanism 70. The leather transfer module 72 conveys the PVC leather 101 to the leather cutting module 73, and the leather cutting module 73 cuts the PVC leather 101. The punching and cutting processes are designed on the same equipment, which reduces equipment costs. Moreover, the whole process does not require manual operation and has high production efficiency.

[0039] like Figure 6 and Figure 7 As shown, a first conveying channel is formed between the upper and lower rows of spring ropes 723. When the PVC leather 101 passes through the first conveying channel, due to the special structure of the spring ropes 723, the friction between the spring ropes 723 and the PVC leather 101 is large, which enables the PVC leather 101 to be conveyed smoothly. The structure is ingenious.

[0040] Furthermore, this embodiment provides at least two adjustment mechanisms 42, and the spacing between two adjacent adjustment mechanisms 42 is adjustable. Each adjustment mechanism 42 includes a base plate 424 whose position can be adjusted along the x-direction. The punching mechanism 50 is fixed to the upper end of the base plate 424, so that the spacing between two adjacent punching mechanisms 50 is adjustable, which can adapt to different punching requirements.

[0041] Furthermore, the diameter of the first roller 721 is smaller than that of the second roller 722. Using two rollers with different diameters allows the spring rope 723 to be tied more tightly, preventing the spring rope 723 from coming loose and causing the first roller 721 or the second roller 722 to slip and spin idly. A rotation drive device 724 is also fixed on the first bracket 71. The output shaft of the rotation drive device 724 is connected to the first roller 721 for transmission. The first roller 721 is driven to rotate by the second rotation drive device 724, which in turn drives the spring rope 723 to circulate and transport. The structure is ingenious.

[0042] Please refer to Figure 3 The conveying mechanism 90 includes two columns 91 fixed to the upper end of the operating table 40 and arranged along the y-direction, an upper conveying roller 92 and a lower conveying roller 93 rotatably disposed between the two columns 91, and a second conveying channel for the PVC material 101 to pass through between the upper conveying roller 92 and the lower conveying roller 93. By setting the conveying mechanism 90, the PVC material 101 can be better guided to be conveyed along the x-direction, and the upper and lower limiting effects of the upper conveying roller 92 and the lower conveying roller 93 can make the conveying flatness of the PVC material 101 better.

[0043] The punching mechanism 50 includes a support frame 51 fixed on the base plate 424, a first lifting drive device 52 fixed on the support frame 51 and driven in the z direction, an upper die head 53 connected to the output end of the first lifting drive device 52, and a lower die head 54 fixed on the support frame 51 and located below the upper die head 53. When the PVC material 101 is conveyed between the upper die head 53 and the lower die head 54 and has traveled a predetermined distance, the first lifting drive device 52 drives the upper die head 53 to press down, and the upper die head 53 punches the air nozzle hole 103 into the PVC material 101. The structure is ingenious.

[0044] The leather cutting module 73 includes a second lifting drive device 731 fixed to the upper end of the first bracket 71 and driven in the z direction, an upper cutter 732 connected to the output end of the second lifting drive device 731, and a lower cutter 733 fixed to the first bracket 71 and located below the upper cutter 732. The upper cutter 732 is driven to move downward by the second lifting drive device 731, thereby cutting the PVC leather 101.

[0045] The generation of static electricity can easily cause a lot of waste material to stick to the upper cutter 732, the lower cutter 733, and the surface of the PVC leather 101. Therefore, in this embodiment, a static electricity elimination module is also provided on one side of the leather cutting module 73. The static electricity elimination module includes a static electricity elimination rod 74 fixed on the third bracket 71. When the surface of the PVC leather 101 is negatively charged, the static electricity elimination rod 74 will attract the positive charge in the radiation area; when the surface of the PVC leather 101 is positively charged, the static electricity elimination rod 74 will attract the negative charge in the radiation area, thereby neutralizing the static electricity on the surface of the PVC leather 101 and achieving the purpose of eliminating static electricity.

[0046] To better guide the PVC leather 101 into the leather transfer module 72, please refer to... Figure 3 and Figure 4 The first support 71 is also provided with a third roller 75, which is located between the conveying mechanism 90 and the leather transfer module 72.

[0047] The operating table 40 is provided with a rack 41 along the x-direction. The adjustment mechanism 42 includes a gear 421 that meshes with the rack 41, a rotating shaft 422 that is connected to the gear 421, and a handle 423 connected to the end of the rotating shaft 422. The rotating shaft 422 is rotatably mounted on the base plate 424. By rotating the handle 423, the handle 423 drives the rotating shaft 422 and the gear 421 to rotate, thereby adjusting the position of the base plate 424 along the x-direction. The punching mechanism 50 is mounted on the base plate 424 of one of the adjustment mechanisms 42, so that the position of the punching mechanism 50 along the x-direction is adjustable to adapt to different punching requirements.

[0048] Please refer to Figure 3 The base plate 424 is also provided with locking bolts 45 at both ends for fixing the base plate 424 and the rack 41. After the position of the adjustment mechanism 42 is adjusted, the base plate 424 and the rack 41 can be fixed by locking bolts 45 to prevent the base plate 424 from loosening and to ensure the subsequent punching accuracy.

[0049] Please refer to Figure 3 and Figure 4 The operating table 40 is also equipped with an inclined pusher plate 43. The pusher plate 43 is located on one side of the cutting mechanism 70 along the x direction. The pusher plate 43 is also equipped with a baffle 44. The cut PVC leather 101 slides down along the pusher plate 43 and is finally blocked by the baffle 44. By setting the pusher plate 43, multiple PVC leather 101s can be stacked and then removed together.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this invention.
