[0002] A Teflon high-temperature cloth shearing device is a mechanical device specifically used for shearing Teflon high-temperature cloth. It is equipped with a shearing knife made of Teflon material and a wear-resistant and high-temperature-resistant grinding layer, and can work stably and efficiently in a high-temperature environment. This device not only improves the shearing accuracy and efficiency, but also ensures the safety and reliability of the operation process, and is one of the important devices in the field of Teflon high-temperature cloth processing.

[0003] The utility model with the publication number of Chinese CN212714243U discloses a shearing device for processing Teflon high-temperature cloth, which includes a bottom plate. A base block is fixed at the upper end of the bottom plate, a convex block is fixed at the upper end of the base block, and a groove is formed along the length direction at the top of the convex block; both ends of the base block are fixed with side plates, one side of the top ends of the two side plates away from each other is fixed with ear plates, and a support rod is fixed between the two ear plates and the bottom plate. A connecting block is slidably installed on the support rod, and a spring is fixed between the connecting block and the ear plate. The spring is sleeved on the support rod. Vertical connecting rods are fixedly arranged on both connecting blocks, and a top plate is fixed between the top ends of the two connecting rods.

[0004] During the implementation of this application, it is found that this technology has the following problems: In the above patent document, the shearing device uses a spring to push the connecting block to move downward, and at the same time drives the top plate to descend through the connecting rod to limit and fix the Teflon high-temperature cloth. It is difficult to accurately control the elastic force of the spring, which may lead to insufficient stability of the limit fixation and affect the shearing accuracy.

[0005] Therefore, a Teflon high-temperature cloth shearing device is proposed. Utility Model Content

Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0024] Refer to Figures 1-4, A Teflon high-temperature cloth shearing device, including a base 1. Four groups of support seats 9 and two groups of support columns 5 are arranged in parallel on the outer surface of the top of the base 1. A limiting main body 2 is arranged on the top of the four groups of support seats 9, and an activity room 4 is arranged on the top of the two groups of support columns 5. A first motor room 3 is arranged on the outer surface of the activity room 4. A lead screw 18 is arranged inside the activity room 4. A motor 14 is arranged inside the first motor room 3. The output end of the motor 14 is fixedly connected to the lead screw 18. A workbench 6 is arranged between the four groups of support seats 9 and the two groups of support columns 5. Bottom contact layers 7 are arranged on both sides of the outer surface of the top of the workbench 6. Second motor rooms 21 and support columns 23 are arranged on the outer surfaces of both sides of the base 1 away from the support columns 5. A winding main body 22 is arranged at the output end of the second motor room 21. The other end of the winding main body 22 away from the second motor room 21 is rotatably connected to the support column 23. Specifically, through the cooperation of the above structures, the Teflon high-temperature cloth can be effectively positioned and controlled, thereby improving the shearing quality.

[0025] Refer to Figures 1-4 , A threaded block 19 is threadedly connected to the outer surface of the lead screw 18. Two groups of second electric cylinders 17 are fixedly connected to the outer surface of the bottom of the threaded block 19. Second output rods 16 are arranged at the output ends of the second electric cylinders 17. A shearing block 20 is arranged on the outer surface of one side of the second output rod 16 away from the second electric cylinder 17. A shearing main body 15 is arranged on the outer surface of the bottom of the shearing block 20. Specifically, the lead screw 18 drives the threaded block 19 to move horizontally. Two groups of second electric cylinders 17 are fixed at the bottom of the threaded block. The electric cylinder 17 drives the second output rod 16 to expand and contract, driving the shearing block 20 to move. The shearing main body 15 is installed at the bottom of the shearing block 20 to achieve efficient shearing operation. The limiting main body 2 includes first electric cylinders 10, first output rods 11 and movable blocks 8. There are two groups of first electric cylinders 10, and first output rods 11 are arranged at the output ends of the two groups of first electric cylinders 10. Movable blocks 8 are arranged on the outer surfaces of one side of the two groups of first output rods 11 away from the first electric cylinders 10. Specifically, the limiting main body 2 is composed of two groups of first electric cylinders 10, which are connected to the movable block 8 through the first output rod 11. When the first electric cylinder 10 is started, the output rod pushes the movable block 8 to move, realizing an accurate limiting function and ensuring the stable progress of the shearing operation.

[0026] Refer to Figures 1-4, a limiting plate 12 is arranged between two groups of movable blocks 8. A top contact layer 13 is arranged on the outer surface of the limiting plate 12 close to one side of the base 1. Specifically, a limiting plate 12 is arranged between two groups of movable blocks 8. When the plate is close to the base, its outer surface is provided with a top contact layer 13 to ensure close fit with the base, achieve stable limiting, and improve the shearing accuracy and efficiency. Activity frames 24 are formed on the outer surfaces on both sides of the limiting body 2, and the movable blocks 8 can move within the activity frames 24. Specifically, activity frames 24 are arranged on the outer surfaces on both sides of the limiting body 2, and the movable blocks 8 can move flexibly within this frame. This design not only ensures the stability of the limiting but also provides sufficient movement space to ensure the smooth progress of the shearing operation.

[0027] Refer to Figures 1-4 , the bottom contact layer 7 and the top contact layer 13 are made of silicone rubber material. Specifically, the matte layer made of silicone rubber material can maintain stable performance in high-temperature environments and at the same time provide sufficient friction to clamp the fabric to ensure the shearing operation.

[0028] The implementation principle of an embodiment of the Teflon high-temperature cloth shearing device of this application is as follows:

[0029] When using the Teflon high-temperature cloth shearing device to shear it, first start the motor in the second motor chamber 21 to make the winding main body 22 connected to its output end rotate. The rotation of the winding main body 22 drives the winding of the Teflon high-temperature cloth. When it is wound to the required shearing position, start the first electric cylinder 10 to make the first output rod 11 connected to its output end move. The movement of the first output rod 11 drives the movable block 8 to move inside the activity frame 24, thereby driving the top contact layer 13 at the bottom of the limiting plate 12 to move downward to jointly clamp the Teflon high-temperature cloth with the bottom contact layer 7. The matte layer made of silicone rubber material can maintain stable performance in high-temperature environments and at the same time provide sufficient friction to clamp the fabric to ensure the shearing operation.

[0030] On the other hand, start the second electric cylinder 17 to make the second output rod 16 at its bottom move downward. The downward movement of the two groups of second output rods 16 drives the shearing main body 15 to move. When the shearing main body 15 reaches the appropriate position, start the motor 14 in the first motor chamber 3 to make the lead screw 18 connected to its output end rotate, thereby driving the threaded block 19 around it to move. The movement of the threaded block 19 drives the two groups of second electric cylinders 17 at its bottom to move, thus completing the shearing work.
