A plug rod 16 is slidably connected to the bottom of the box body 10, and a block 14 is fixedly connected to the top of the plug rod 16. A telescopic spring 15 is provided at the bottom of the block 14. A spring groove 17 is provided at one end of the workbench 1, and several groups of return springs 18 are fixedly connected to the inside of the spring groove 17. The tops of the several groups of return springs 18 are fixedly connected to a pressure slider 19, and a cutting groove 20 is provided on the top of the pressure slider 19. A circulation pipe 21 is provided inside the pressure slider 19, and a storage groove 22 is provided on one side of the outer surface of the workbench 1.
[0033] Specifically, a protective pad 8 is fixedly connected to the bottom of the pressing plate 7. The protective pad 8 is made of rubber material. The structural rubber has excellent elasticity and wear resistance, and can provide a buffering effect when the pressing plate 7 contacts the plastic bag, reducing the damage to the plastic bag caused by direct friction, and also protecting the surface of the pressing plate 7 from being scratched by sharp objects on the plastic bag.
[0034] Specifically, a rubber sleeve is provided at the junction of the outer wall of the insertion rod 16 and the box body 10. The rubber sleeve can absorb the vibration caused by mechanical movement, reduce noise and impact, and the bottom of the insertion rod 16 is conical. This structure makes it more convenient to punch holes in plastic bags, reduces manual operation, and improves the degree of automation.
[0035] Specifically, the top of the telescopic spring 15 is fixedly connected to the bottom of the block 14 , and the bottom of the telescopic spring 15 is fixedly connected to the bottom of the box 10 . This structure allows the insertion rod 16 to perform vertical reciprocating motion and be reset by the telescopic spring 15 .

The use of the second hydraulic cylinder 28 of this structure provides powerful power and precise control, so that the cutter 29 can cut quickly and accurately.
[0040] Working principle: When using the device, first fix the plastic bag, start the first hydraulic cylinder 6, and then the output end of the first hydraulic cylinder 6 drives the pressure plate 7 to move downward, and then the pressure plate 7 can be adjusted to a suitable position, and then the plastic bag can be placed on the conveyor belt 4 for cutting. Start the first motor 2 to drive the conveyor belt 4 to move, and then the movement of the conveyor belt 4 drives the plastic bag to move. When it is necessary to punch a hole in the plastic bag, turn on the second motor 12 in the box 10, and the second motor 12 drives the cam 13 to rotate. After the cam 13 rotates, the convex point will press the block 14, and the block 14 will press the insertion rod 16 together with the telescopic spring 15. After the convex point rotates away, the telescopic spring 15 will bounce the insertion rod 16 back to its original position by its own elastic force, thereby quickly realizing the punching of the plastic bag and reducing manual operation. When cutting the plastic bag, when the tool on the second hydraulic cylinder 28 is pressed down to press the cutting groove 20 to cut, the cutting groove 20 will be forced to drive the pressure slider 19 to move downward, squeezing the extrusion and adsorption airbag 23. When the tool is finished cutting and returns to its position, the extrusion and adsorption airbag 23 will be reset to generate a certain adsorption force, so that it can adsorb some plastic bag scraps remaining on the cutting groove 20 through the circulation pipe 21 and bring them to the storage groove 22. The generated debris will fall to the inside of the drawer 26, which is convenient for the collection of debris. When the debris needs to be cleaned, the drawer 26 can be moved by the handle, and then the slider 25 is driven by the drawer 26 to move on the inside of the storage groove 22. Then the drawer 26 can be removed and cleaned, which facilitates the cleaning work of the cutting device and reduces the workload of the staff.
