Description

Technical Field

[0001] The utility model relates to the technical field of release film coating, in particular to a release film coating device. Background Art

[0002] Release film refers to a film with distinguishable surface. When the release film comes into contact with a specific material under limited conditions, it is not sticky or has slight stickiness. In order to obtain better use effect, the release film needs to be coated during processing.

[0003] In the existing coating process, a traction device is used to make the release film pass through the coating device, and the coating process is completed while moving in the coating device. After the process is completed, the release film is pulled out by the traction device on the other side for subsequent processing. However, in actual use, the traction device mostly uses rollers for guidance. During the guiding process, the release film needs to maintain a certain tension and have a smooth surface. When only rollers are used for guidance, it is impossible to maintain the tension while eliminating wrinkles on the surface of the release film. The operator needs to observe with the naked eye and control the tension while stopping the machine for manual operation if wrinkles are found, which reduces work efficiency. Utility Model Content
