Description

Technical Field

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

[0002] Plastic bags are bags made of plastic (commonly used plastics include polypropylene, polyester, nylon, etc.) as the main raw material. They are indispensable items in people's daily lives and are often used to hold other items. Some plastics with sealing functions and the function of being able to be re-sealed after being disassembled need to be added with zippers during the production process, and the zippers need to be pressed together with the plastic bags during the production process. Generally, for the zipper feeding of plastic bags, only a carton is used to place the material tray and a vertical pole is used to turn the zipper, which is transported to the feeding structure and pressed together with the plastic bag. The carton is easily affected by moisture and easily damaged by squeezing, which affects the stability of the material tray. It also does not have the effect of arranging the zipper, so that the zipper cannot be fed more smoothly, which easily causes deformation and damage to the zipper. Moreover, the material tray is directly placed in the carton, which easily causes the material tray to be scattered during the feeding process, and may cause the zipper to be entangled, affecting the feeding effect. For this reason, the utility model proposes a feeding mechanism and a plastic bag production zipper pressing device to solve the above problems. Utility Model Content
