Description

technical field [0001] The present invention relates to a liquid removal device, and in particular to a scraper, a liquid discharge device and a liquid removal system. Background technique [0002] In the preparation process of optical film, it is often necessary to soak it in various process baths for dyeing and crosslinking preparation process, surface treatment preparation process or water washing process, and then wind up after drying. However, before the drying of the optical film material, the liquid remaining on the surface of the optical film material, such as processing liquid and / or washing liquid, is often unable to be effectively removed, and these liquids are prone to water spots and / or dirt after drying Stain defects, which in turn affect the optical properties of the optical film. Contents of the invention [0003] The purpose of the present invention is to provide a scraper, a liquid discharge device and a liquid removal system, which are used to reduce th...
