Description

Technical Field

[0001] This utility model belongs to the field of self-cutting technology of mid-layer wrapping film, specifically relating to a self-cutting device for mid-layer wrapping film in packaging. Background Technology

[0002] Food packaging bags are a type of packaging design. They were developed to facilitate food preservation and storage. Packaging plays a vital role in reducing transportation safety risks. Packaging bags can also prevent food from being mixed with other goods. Furthermore, food packaging can reduce the possibility of food theft.

[0003] A Chinese utility model patent (Publication No.: CN217296558U) discloses a packaging film winding device, including a base. Symmetrically distributed fixing frames are fixedly mounted on the top of the base. Symmetrically distributed auxiliary rollers are arranged on both fixing frames. A fixing plate is fixedly mounted on one side of the top of the base. A horizontal plate is fixedly mounted on the top of the fixing plate. A winding roller is arranged on the front of the fixing plate. This packaging film winding device utilizes the coordinated use of a base, fixing plate, pressure roller, mounting frame, mounting rod, horizontal plate, movable plate, stop block, fixing frame, auxiliary roller, handle, positioning groove, slide groove, slider, positioning rod, slide bar, spring, and winding roller. The spring provides a reaction force to the movable plate, causing the mounting frame to continuously press the film during the winding process, ensuring that the final rolled film is tight and compact, facilitating storage and future use.

[0004] However, in implementing the relevant technology, the above-mentioned packaging film winding device has the following problems: the existing technology cannot cut the winding film after winding, thus affecting the winding efficiency of the film in the later stage. The device uses a cutting blade to cut the winding film after winding, thereby improving the winding efficiency of the film in the later stage. Therefore, a self-cutting device for winding packaging film is proposed. Utility Model Content
