Diffusion film coating production device

Abstract

The invention provides a diffusion film coating production device. The diffusion film coating production device comprises an unwinding device, a coating device, a drying device and a winding device which are sequentially arranged and installed; the coating device comprises a supporting base, and further comprises a feeding guide roller, a supporting frame and a discharging guide roller which are sequentially and fixedly installed on the supporting base, and a painting device and a secondary rolling assembly are installed on the supporting frame; the drying device comprises an oven, and furthercomprises a heat insulation plate and a vertical partition plate which are fixed into the oven, and the vertical partition plate is mutually perpendicular to the heat insulation plate; the inner partof the oven is divided into a photocuring area, a heat drying area and a buffer area by the heat insulation plate and the vertical partition plate, wherein the heat drying area and the buffer area are located above the photocuring area; and after a diffusion film on the unwinding device is coated by the painting device and leveled by the secondary rolling assembly, the diffusion film is sequentially dried by the heat drying area and the photocuriing area, and then is winded by the winding device. The situation of caking and wrinkling of a diffusion film produced by an existing diffusion filmcoating device adopting a single coating and single drying method is improved.

Description

Technical field [0001] The invention relates to the field of diffusion film processing equipment, in particular to a diffusion film coating production device. Background technique [0002] The diffuser film has the function of diffusing light, that is, the light is scattered on its surface to spread the light softly and evenly. The diffuser film is mainly on the transparent substrate, such as applying optical astigmatism particles on the PET base film and drying it. , Drying equipment is often used for drying, and the entire process includes base film release, paint coating, drying and shaping, and winding into drums. [0003] In the existing diffusion film coating equipment, the base film is immediately sent to the drying equipment for thermal drying after coating, and a single drying method is adopted. The entire process causes uneven coating of the diffusion film and results in knots after drying. Blocks, wrinkles. Summary of the invention [0004] In view of the shortcomings i...
