Description

Technical Field

[0001] The utility model relates to the technical field of film processing, and more specifically, to an automatic film spraying device. Background Art

[0002] Functional film products made of polymer substrates are becoming more and more popular in various fields. Especially for functional films with optical functions, polymer films (such as PET, PC, PMMA, PVC, TAC, etc.) have excellent optical and physical mechanical properties. By adding functional coatings to the films through spraying devices, such as surface hardening coatings or some special functional coatings, the functional properties of the polymer film materials are improved, and the application value is increased.

[0003] Based on the above, the inventor found that: the existing spraying devices mainly consist of a spraying component and a heating component. After the spraying component completes the spraying work on the film surface, the heating component then heats and dries the paint on the film surface to improve the spraying efficiency. However, the spraying work of the film usually takes a long time, resulting in the heating component continuously sucking air from the outside and filtering impurities through a filter screen. The filter screen is prone to clogging during long-term operation. Therefore, in view of this, the existing structure is studied and improved to provide an automatic film spraying device, aiming to achieve a more practical value. Summary of the Utility Model
