Description

Technical Field

[0001] The utility model relates to the technical field of plastic films, in particular to a bag cutting device for producing plastic film bags. Background Art

[0002] Plastic film bags, also known as 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. They are widely used because of their low cost, extremely light weight, large capacity, and easy storage. Plastic film bags need to be cut using a bag cutting device after production. Most bag cutting devices are slitting machines. According to publication number CN219927098U, a bag cutting device for producing plastic film bags is disclosed, including a bag cutting table, a slitting frame, a support frame, and a hydraulic cylinder. The slitting frame is movably connected to the top of the bag cutting table, the bottom end of the support frame is fixedly connected to the top of the bag cutting table, the bottom end of the hydraulic cylinder is fixedly connected to the top of the support frame, the bottom end of the support frame is fixedly installed with a fixed column, and the output shaft of the hydraulic cylinder is drivingly connected to a telescopic column. The utility model discloses a bag cutting device for producing plastic film bags, which is provided with an auxiliary sleeve, a fixed plate, and a telescopic column. The telescopic column comprises a plate, a movable column, a reset spring and a pressing plate, wherein the fixed column is fixed and stationary, and when the telescopic column moves downward, the fixed plate and the pressing plate will be driven to move downward at the same time, so that the pressing plate can move stably on one end of the movable column, and the multiple pressing plates arranged at equal intervals increase the pressing area on the surface of the plastic film bag, thereby preventing the plastic film bag from moving with the bumps of the bag cutting table. However, during operation, large quantities of plastic film bags cannot be cut, and cutting is required in a single group, which affects efficiency.
