[0002] Plastic packaging bags refer to bags used to package various items, making it convenient to transport and store goods during the production and circulation process. They are widely used in daily life and industrial production. Plastic packaging bags are made of plastic as raw material and are used to produce various items in life. They are widely used in daily life and industrial production. In the processing of plastic packaging bags, sometimes in order to facilitate people to carry and pull plastic bags, it is usually necessary to punch holes to tie them for easy carrying, so the plastic packaging bags need to be punched.

[0003] Most existing punching devices for plastic packaging require manual pulling and moving of the plastic when punching multiple holes in a long length of plastic, resulting in poor punching effect, easy displacement of the punching position, and inconsistent distances between multiple holes, thereby reducing the efficiency and quality of plastic punching.

[0004] A punching device for plastic packaging disclosed in the Chinese utility model patent application publication CN202023338269.0 includes a bracket and a movable support plate; a punching member is fitted within the internal clearance of a mounting groove; a punching ring is provided on the outer surface of the punching member; and a through-hole is provided at the center of the upper surface of the support plate. Although this punching device for plastic packaging can perform punching operations on plastic holes of different apertures, greatly expanding the scope of application of the utility model, it has the disadvantage of requiring manual adjustment of the position of the plastic when punching holes in different positions on the same plastic. This also results in a slow punching efficiency when a large number of holes are to be punched on the same plastic. Utility Model Content

Two limit plates 16 are fixedly connected to both sides of the receiving box 2, and two limit cylinders 17 are rotatably connected between the two limit plates 16. The two ends of the top of the bottom plate 1 are respectively provided with a receiving cylinder 18 and a feeding cylinder 19. The side of the support frame 3 is fixedly connected with a positioning frame 22, and the side of the positioning frame 22 is rotatably connected with a rotating plate 25.
