Description

Technical Field

[0001] The utility model relates to a film scraping device, in particular to a laser PE film removing device. Background Art

[0002] PE film is a thin film made from PE particles. It offers advantages such as moisture resistance and low water permeability. Depending on the manufacturing method and control methods, PE film can be manufactured into products with different properties, including low-density, medium-density, high-density polyethylene, and cross-linked polyethylene.

[0003] When stamping metal parts, the surface of the raw material must be protected by a protective film during processing. Due to the requirements of stamping, the area surrounding the punched holes cannot be covered with protective film, so this part of the protective film must be removed before the next step of processing. Current devices for removing PE film typically use a blade to directly contact the PE film and cut it open. However, this method may cause the entire PE film to be scratched and must be discarded, resulting in a reduced yield rate. Utility Model Content
