[0002] The perforation device in a food preservation bag laminating machine is used during the manufacturing process of food preservation bags. After the lamination process is completed, tiny air holes are punched into the plastic film using specialized equipment. The main function is to allow a suitable amount of oxygen and carbon dioxide exchange in food preservation bags that are used to package fresh products such as vegetables and fruits. This prevents excessive accumulation of moisture and ethylene gas inside the bag, thereby extending the shelf life of the food.

[0003] The existing punching devices have the following problems: The most common perforation device currently available uses a needle roller to perforate plastic bags. Over time, the needles on the needle roller often develop various problems, such as becoming blunt, bending, or even breaking. However, the needles on existing needle rollers are all molded in one piece, and it is not convenient to replace the damaged parts. Instead, a new needle roller must be replaced, which leads to high costs and difficulty in maintenance. Utility Model Content
