A contact device 1 is slidably installed inside the support device 2. The support device 2 includes a cutter 15, a guide rod 16, a connecting rope 17, a partition plate 18, a support base 19, a first gear 20, a stop frame 21, a second gear 22, a drive motor 23, a thread reel 24, and a base 25.

The guide rod 16 is symmetrically fixedly installed between the stop frame 21 and the cutter. Between the cutter 15, the support chassis 19 is fixedly installed on the base 25 near the top of the cutter 15, the partition plate 18 is symmetrically fixedly installed on the bottom side of the cutter 15 away from the guide rod 16, the spool 24 is rotatably installed on the base 25 near the top of the stop 21, and the spool 24 is located between the two stops 21, the first gear 20 is fixedly installed on the top of the spool 24, the connecting rope 17 is fixedly installed on the outer ring of the spool 24, the drive motor 23 is fixedly installed on the end of the base 25 away from the cutter 15, and the second gear 22 is fixedly installed on the top center of the drive motor 23.

[0022] Contact device 1 includes a displacement bracket 4, a return spring 5, a support block 6, a first piston rod 7, an L-shaped air cylinder 8, a magnetic absorbing plate 9, an iron plate 10, a U-shaped connecting plate 11, a second piston rod 12, a lower end plate 13, and an upper end plate 14. The return spring 5 is fixedly installed at both ends of the displacement bracket 4, and the support block 6 is fixedly installed at the end of the return spring 5 away from the displacement bracket 4. The L-shaped air cylinder 8 is symmetrically fixedly installed on the side end of the displacement bracket 4. The first piston rod 7 is slidably inserted into the bottom end of the L-shaped air cylinder 8. The second piston rod 12... Rod 12 is slidably inserted into the top of L-shaped air cylinder 8. U-shaped connecting plate 11 is fixedly installed on the top of the second piston rod 12. Magnetic suction plate 9 is fixedly installed at both ends of the bottom of U-shaped connecting plate 11. Upper end plate 14 is fixedly installed between the two magnetic suction plates 9. Iron plate 10 is symmetrically fixedly installed on the top of displacement bracket 4 near L-shaped air cylinder 8. Lower end plate 13 is symmetrically fixedly installed on the side of displacement bracket 4 away from L-shaped air cylinder 8. It is installed on base 25 through support block 6 so that it can support the return spring 5 to work.

[0023] The interior of the L-shaped air cylinder 8 is hollow, and the first piston rod 7, the L-shaped air cylinder 8 and the second piston rod 12 are in a sealed state. When the first piston rod 7 moves inside the L-shaped air cylinder 8, it can drive the second piston rod 12 to move up and down.

[0024] The displacement bracket 4 is slidably sleeved on the guide rod 16. The tooth distribution angle of the second gear 22 is 180°. The end of the connecting rope 17 away from the first gear 20 is connected to the displacement bracket 4. When the drive motor 23 is running, it can drive the second gear 22 to rotate.

[0025] Plastic gaskets are fixedly installed at the bottom of the upper end plate 14 and the top of the lower end plate 13 respectively. A key is fixedly installed on the side of the upper end plate 14 near the displacement bracket 4, and slots are symmetrically opened inside the side of the displacement bracket 4 near the lower end plate 13. The upper end plate 14 can be moved in the slots inside the displacement bracket 4 by the key on the upper end plate 14, so that the upper end plate 14 can move up and down in a straight line.

[0026] The support base 19 has symmetrical grooves on the side end near the first gear 20, and the lower end plate 13 is aligned with the grooves. When the displacement bracket 4 is reset, the lower end plate 13 can be inserted into the groove, so that the lower end plate 13 can be moved to the bottom of the fabric 3.

[0027] Working principle: In use, first place the fabric 3 on the top of the support base 19 until the end of the fabric 3 is flush with the surface of the support base 19 near the connecting rope 17. At this time, the drive motor 23 can be turned on, driving the second gear 22 to rotate through the first gear 20. At this time, the first gear 20 will lose the meshing force of the second gear 22, so the return spring 5 can drive the displacement bracket 4 to move and reset. At this time, the displacement bracket 4 can slide on the outer ring of the guide rod 16 until the displacement bracket 4 is reset. Then, it can drive the lower end plate 13 to move into the groove inside the support base 19. At this time, the displacement bracket 4 can drive the iron plate 10 to contact the partition plate 18. Since the opposite ends of the partition plate 18 and the iron plate 10 are both set at 45°, the partition plate 18 can smoothly... The first piston rod 7 moves smoothly between the iron plate 10 and the magnetic plate 9. At this time, the partition plate 18 can separate the magnetic plate 9 from the iron plate 10, so that the U-shaped connecting plate 11 can move downward, causing the second piston rod 12 to move into the interior of the L-shaped air cylinder 8. The first piston rod 7 can move outward from the interior of the L-shaped air cylinder 8. When the magnetic plate 9 moves downward, it can drive the upper end plate 14 to move downward. When the upper end plate 14 moves downward, the bottom end of the upper end plate 14 and the top end of the lower end plate 13 are fixedly installed with mutually cooperating magnets, so that the upper end plate 14 can be attracted and attached to the lower end plate 13, and the fabric 3 can be located above the groove of the supporting base 19, so that when the upper end plate 14 moves downward and is attracted and attached to the lower end plate 13, the fabric 3 can be clamped. Then, when the second gear 22 rotates again to the position of the lower end plate 13, the fabric 3 can be clamped. When the first gear 20 meshes, it can drive the first gear 20 to rotate. When the first gear 20 rotates, it can drive the thread wheel 24 to rotate. When the thread wheel 24 rotates, it can pull the displacement bracket 4 to move away from the cutting machine 15 through the lower end plate 13. Thus, the displacement bracket 4 can pull and stretch the fabric 3 until the displacement bracket 4 drives the first piston rod 7 to move to contact the stop 21. When the displacement bracket 4 continues to move, the first piston rod 7 can enter the interior of the L-shaped air cylinder 8 due to the restriction of the stop 21. Thus, the second piston rod 12 can move upward. At this time, the U-shaped connecting plate 11 can drive the magnetic suction piece 9 and the upper end plate 14 to move upward. Thus, the upper end plate 14 can separate from the lower end plate 13, releasing the fabric 3. At the same time, the cutting machine 15 can be turned on to cut the fabric 3. When the connecting rope 17 pulls the displacement bracket 4 to its limit position away from the cutting machine 15, the first piston rod 7 can fully enter the interior of the L-shaped air cylinder 8, so that the magnetic suction plate 9 can rise to contact the iron plate 10. The magnetic suction plate 9 and the iron plate 10 are attracted and adhered, which can temporarily restrict the upper end plate 14. Subsequently, when the second gear 22 rotates to disengage from the first gear 20, the second gear 22 will lose engagement, so that the return spring 5 can drive the displacement bracket 4 to move and reset, causing the lower end plate 13 to move into the groove inside the support base 19. After the fabric 3 is cut, the remaining fabric 3 can cover the top of the groove of the support base 19, so that after the displacement bracket 4 is reset, the lower end plate 13 is located below the fabric 3. By repeating the above steps,The fabric 3 can be repeatedly pulled to a specified length for easy cutting. A release groove is provided inside the base 25, allowing the fabric 3 to be discharged outwards after cutting, thus completing the process.
