Description

Technical Field

[0001] The utility model relates to the technical field of plastic bag punching, in particular to a punching mechanism for plastic bag production. Background Art

[0002] Punching holes in plastic bags is a common packaging method, usually used to make plastic bags easier to hang or breathe. There are many ways to punch holes, such as using special punching tools or penetrating with sharp objects. Before punching holes, you need to consider the location and number of holes to ensure that the items in the bag will not be damaged or affected in use. In addition, the bag should be used promptly after punching to avoid affecting the preservation and protection of the items in the bag.

[0003] Chinese patent announcement number CN213441412U discloses a punching machine for plastic bag production, which relates to the technical field of plastic bag punching, including a frame, a punching device and a winding device; the punching device includes a first lifting frame, a telescopic cylinder, a pressing block, a sliding mechanism, a punching nail, an elastic member and a nail groove. When in use, the telescopic cylinder, the pressing block and the punching nail are driven downward by the first lifting device. When the pressing block presses the plastic bag, the punching nail is hit by the telescopic cylinder to punch the plastic bag. The nail groove is set to enable the punching nail to extend under the plastic bag to achieve a better punching effect. With this arrangement, after the pressing block presses the plastic bag, the punching position will not be pulled when punching, thereby ensuring the accuracy of the punching, and the appearance is beautiful.
