Description

Technical Field

[0001] The utility model relates to the technical field of winding devices, in particular to a plastic packaging film winding device with position limiting protection. Background Art

[0002] Plastic packaging film is a thin film packaging material made of plastic as the main raw material. It has good protection, barrier properties, weather resistance and processability. Rewinding is an important step in the production process of plastic film. After production, if the plastic packaging film is in a scattered state, it will take up a lot of space and be easily damaged. By rewinding, the film can be organized into a compact roll, effectively saving storage space.

[0003] In the prior art, a winder usually winds the film onto a winding roller by friction. The surface of the winding roller is usually made of rubber or other materials with a certain friction coefficient. The film is in close contact with the surface of the winding roller. When the winding roller rotates, the film is wound by friction. However, it is not convenient to limit the winding process of the plastic packaging film when it is currently wound. The plastic packaging film roll is prone to loosening or deviation due to excessive tension during winding, which will affect the winding effect of the plastic packaging film. Utility Model Content
