Description

Technical Field

[0001] The utility model relates to the technical field of anti-rust bag film processing, in particular to an automatic film stretching device for an anti-rust bag. Background Art

[0002] Anti-rust bag film is a special packaging material, mainly used to protect metal parts from rust. This film is a high-tech product developed based on the combination of polymer materials and vapor phase rust prevention technology. Its working principle is that in a closed environment, the VCI component will gradually evaporate into gas, evenly covering the metal surface to form a protective film. This film can effectively prevent moisture, oxygen and other factors in the air that cause metal corrosion from directly contacting the metal surface, thereby achieving an anti-rust effect.

[0003] With the development of industry, the requirements for rust prevention of metal parts are getting higher and higher. Anti-rust bags have been widely used as an effective means of rust prevention. In the production process of anti-rust bags, the stretching quality of the film directly affects the performance of the anti-rust bags. The traditional film stretching method is inefficient and uneven, and it is not possible to adjust the stretching of the film well. The adjustment is more troublesome, which reduces the stretching efficiency. Utility Model Content
