At present, plastic film packaging has been widely used in food, medicine, chemical industry and other fields, and has brought great convenience to people's lives. In the production process of plastic film, it is necessary to punch holes on the surface to facilitate subsequent operations.

[0003] Most existing punching devices use a roller punching method, that is, during the movement of the film, the surface of the film is statically cut by a cutting drill rod fixed on the surface of a roller-like object. The punching efficiency is high and the operation is convenient, but the position and number of holes cannot be easily adjusted according to actual usage, which affects the actual use effect of the punching device. In addition, the holes after static pressure cutting will leave film waste, which will fly everywhere, making it difficult to collect and increasing the difficulty of subsequent cleaning.

[0022] The material receiving roller 3 and the material feeding roller 5 are respectively located on both sides of the rotating roller 9. Both ends of the rotating roller 9 are fixedly welded to the rotating shaft 8, and one end of the rotating shaft 8 is rotatably connected to the side surface of the fixing plate 6. The electromagnetic sleeves 11 are evenly distributed in a linear array inside the rectangular groove 10. The electromagnetic sleeves 11 are electrically connected to the switch 15 through wires. The number of the electromagnetic sleeves 11 is the same as that of the switch 15. One end of the electromagnetic sleeve 11 is slidably connected to the outside of the punching needle 13 through a circular through hole. The outer diameter of the magnetic column 12 is adapted to the inner diameter of the electromagnetic sleeve 11. The magnetic column 12 is slidably connected inside the electromagnetic sleeve 11. The return spring 14 is located between the electromagnetic sleeve 11 and the magnetic column 12. When the plastic film moves under the action of the material receiving roller 3, the driving motor 7 makes the rotating roller 9 rotate. When the rotating roller 9 rotates to the bottommost position, the signal receiver 17 receives the signal emitted by the signal transmitter 16, so as to energize the electromagnetic sleeve 11 by using the controller 25, further making the magnetic column 12 drive the punching needle 13 to move outward. One end of the punching needle 13 passes through the plastic film and extends into the limiting hole 19 to complete punching. Subsequently, under the elastic force of the return spring 14, the magnetic column 12 and the punching needle 13 return to their original positions, facilitating the next punching. One side of the collection box 18 is cooperatively connected with the sealing plate 24 through bolts. The side surface of the sealing plate 24 is adhesively fixed to the sealing ring. The collection box 18 has through holes on both sides. The inside of the collection box 18 is communicated with the fan 20 through the through holes. The shape of the filter plate 23 is "C"-shaped. The inside of the filter plate 23 abuts against the side surface of the cleaning plate 22. The edge of the cleaning plate 22 is fixedly welded to the collection box 18. After the punching needle 13 completes punching inside the limiting hole 19, the air inside the collection box 18 is exhausted by the fans 20 on both sides to form a negative pressure, so that the film waste formed by punching can be sucked into the collection box 18 and collected inside the collection box 18 through the filter plate 23, avoiding scattering in the air.

[0023] Working principle: When in use, the staff passes the plastic film through the bottom of the rotating roller 9 and fixes it on the outside of the receiving roller 3 through the unwinding roller 5. When the plastic film moves under the action of the receiving roller 3, the driving motor 7 makes the rotating roller 9 rotate. When the rotating roller 9 rotates to the bottom, the signal receiver 17 receives the signal sent by the signal transmitter 16, and then uses the controller 25 to energize the electromagnetic sleeve 11, further making the magnetic column 12 drive the punching needle 13 to move outward, and one end of the punching needle 13 passes through the plastic film and extends to the inside of the limit hole 19 to complete the punching. Then, under the elastic force of the reset spring 14, the magnetic column 12 and the punching needle 13 return to their original positions, which is convenient for the next punching. In addition, the opening or closing can be selected according to the actual use. Turn off the switch 15 corresponding to the position of the electromagnetic sleeve 11. When drilling, only the electromagnetic sleeve 11 in the turned-on state can be energized for drilling, so as to adjust the drilling position and the number of holes. After the punching needle 13 completes drilling inside the limit hole 19, the air inside the collecting box 18 is discharged through the fans 20 on both sides to form a negative pressure, so that the film waste formed by the punching can be sucked into the collecting box 18 and collected in the collecting box 18 through the filter plate 23. The cleaning plate 22 is driven to move by the driving cylinder 21, so that the waste adsorbed on the surface of the filter plate 23 is scraped off and squeezed out with the sealing plate 24. Then, the waste extruded into blocks can be cleaned by removing the bolts on the outside of the sealing plate 24.
