Description

Technical Field

[0001] The utility model relates to the technical field of PETG film roll replacement, and more specifically, to an auxiliary device for PETG film roll replacement. Background Art

[0002] PETG film is a film material made of polyethylene terephthalate. It has high transparency, making it a substitute for glass in many applications. It has good heat resistance and can withstand high temperatures within a certain temperature range. PETG film is widely used in packaging, printing, advertising, electronic product protective film and other fields. When a roll of PETG film is used up, it needs to be replaced with a new roll in time. The overall deadweight of the existing device and roll film is large, and the long-term suspended setting causes serious damage to the correction mechanism, and the subsequent maintenance and replacement costs are also high.

[0003] The utility model with announcement number CN215946266U discloses an auxiliary device for film roll correction, which is provided by setting a supporting cylinder and a roller, wherein the roller is arranged in contact with the ground. During the film roll correction process, the frame for supporting the film roll can adapt to the CD direction for reciprocating motion, thereby improving the movement stability and safety of the entire device, and to a certain extent, its service life, etc.

[0004] During the deviation correction process of the auxiliary device, the frame for supporting the film roll can reciprocate, thereby improving the movement stability and safety of the entire device. However, the PETG film is prone to generate static electricity during winding and use, which is inconvenient to remove, affecting the quality of the subsequent PETG film. Utility Model Content
