Description

TECHNICAL FIELD

[0001] The utility model relates to the processing field of release film, especially relates to a drying device for release film processing. BACKGROUND

[0002] Release film is a kind of film with separation characteristics on the surface. It is usually made by coating release agent on the basis of plastic film (such as polyester film, polypropylene film, etc.). The main function of release agent is to reduce the adhesion of film surface, so that other materials can easily separate from its surface. In the production process of release film, the coating machine will coat silicone oil or other release agent on the substrate, and the drying device will provide suitable temperature and air flow to make the solvent in the release agent evaporate quickly, so as to realize uniform drying and fixation of the release agent.

[0003] The hot air flowability in the traditional hot air drying device is poor, which cannot quickly take away the moisture or solvent on the surface of release film, and there is no high-efficiency circulation path, so that the hot air cannot be updated in time after contacting the release film, which reduces the evaporation efficiency. In the electric heating drying device, only heat radiation and weak natural convection are used to dry the release film, and the heat transfer is relatively slow, which cannot quickly transfer heat to the surface of release film and promote water evaporation like circulating hot air, resulting in the problem of low drying efficiency of the drying device.
