Technical Field

[0001] The utility model relates to the technical field of punching devices, in particular to a middle-sealed bag punching device. Background Art

[0002] Middle-sealed bags are generally made of PE polyethylene, PP polypropylene, and synthetic resins are almost all used in plastics. Resin is the main component of plastics and plays the role of adhesive, which can glue other components of plastics into a whole. Although adding various additives can change the properties of plastics, resin is the fundamental factor that determines the type, performance and use of plastics. During the production process of middle-sealed bags, according to the design and use requirements of the middle-sealed bags themselves, it is often necessary to punch holes in the middle-sealed bags.

[0003] At present, when the punching device for the middle sealed bag needs to perform punching operations of different shapes, it is impossible to quickly change the shape of the holes, so the staff needs to change them manually, which reduces the work efficiency. In addition, the waste after the holes are punched will accumulate on the workbench, which wastes time to clean up.

[0004] Therefore, in view of the above problems, we propose a middle-sealed bag punching device. Utility Model Content
