A pushing component 4 is fixedly installed on the punching mechanism 3, and the punching mechanism 3 is located between the auxiliary conveying component 1 and the auxiliary conveying component 2. The device is installed on the plastic bag production line, which enables continuous punching operation. The pusher component 4 can push out the waste generated during the punching process. The drilling mechanism 3 consists of a supporting base plate 5, several cylinders 6, a limiting support plate 7, several cylinders 8, a limiting pressure plate 9, and several drilling components 10. Cylinders 6 and 8 are fixedly installed at the four corners of the top of the supporting base plate 5. The limiting support plate 7 is fixedly installed at the top of cylinder 6. The limiting pressure plate 9 is located at the top of the limiting support plate 7 and is fixedly connected to cylinders 8. The drilling components 10 are fixedly connected to the top of the limiting pressure plate 9. The limiting pressure plate 9 has several limiting through holes 11, and the limiting support plate 7 has several limiting through holes 11. There are several limiting through holes 12 aligned with the limiting through hole 11. The punching assembly 10 consists of a Z-shaped support 13, a cylinder 14, and a punching head 15. The Z-shaped support 13 is bolted to the top of the limiting pressure plate 9. The cylinder 14 passes through the top of the Z-shaped support 13 and is fixedly connected to the Z-shaped support 13. The punching head 15 is fixedly installed at the bottom of the cylinder 14. The top of the limiting pressure plate 9 has several threaded holes 16 corresponding to the limiting through holes 11 and the limiting through holes 12. During punching, the conveying of the plastic bag is stopped, so that the plastic bag is stationary. Cylinder 1 6 drives the limiting plate 7 to move upward, so that the limiting plate 7 is in contact with the bottom surface of the plastic bag. Cylinder 2 8 drives the limiting pressure plate 9 to move downward, so that the limiting pressure plate 9 is in contact with the top surface of the plastic bag. Then, the punching head 15 is driven downward by cylinder 3 14. The punching head 15 passes through the limiting through hole 11 and the limiting through hole 2 12 to punch the plastic bag. The punching waste moves to the top of the supporting base plate 5. The installation position of the punching component 10 can be adjusted according to the width of the plastic bag. At the same time, multiple limiting through holes 11 and 2 12 are set, so that punching can be performed on plastic bags of different widths. The pushing assembly 4 consists of a support block 17, a cylinder 18, a pushing plate 19, and two limiting rods 20. The support block 17 is fixedly connected to the top of the support base plate 5.

The limiting rods 20 are fixedly connected to one side of the pushing plate 19 and slide through the support block 17. The waste material moves to the top of the support base plate 5, and the pusher plate 19 is moved by the cylinder 4 18 to push the waste material out and avoid the accumulation of waste material. Auxiliary conveying component 1 and auxiliary conveying component 2 are both composed of support frame 1 21, support frame 2 22, rotating roller 1 23, rotating roller 2 24 and servo motor 25.

A pushing component consisting of a support block, cylinder (fourth type), a pusher plate, and two limiting rods can push away the waste generated during the punching process, preventing waste accumulation. Auxiliary conveying components (first and second types) consisting of support frame (first and second types), rotating roller (first and second types), and a servo motor can assist in conveying the plastic bags, improving the stability of plastic bag conveying and reducing the possibility of plastic bag deformation.
