Title:
FILM SURFACE FLATTENING ASSEMBLY AND HORIZONTAL COATING PRODUCTION LINE
Document Type and Number:
WIPO Patent Application WO/2023/184985
Kind Code:
A1
Abstract:
A film surface flattening assembly, comprising: an upper roller (1) having a first roller surface; a lower roller (2) having a second roller surface, wherein the second roller surface is configured to match the first roller surface to squeeze a film to be coated (4), said film (4) passes between the first roller surface and the second roller surface, and the center line of the lower roller (2) and the center line of the upper roller (1) are staggered in the moving direction of said film (4); and a flattening roller (3) spaced apart from the lower roller (2) in the moving direction of said film (4), the flattening roller (3) having a third roller surface configured to contact a film surface, and the third roller surface being of an arc structure the middle of which is high and both ends of which are low. According to the film surface flattening assembly, the film surface is tightened by means of the upper roller (1) and the lower roller (2), so that when passing through the flattening roller (3), a tensile force gradually increasing from the edge to the middle is applied to the film surface by means of the arc structure of the flattening roller (3), so as to flatten the film surface, thereby avoiding the problem of inward shrinkage of two sides of the film surface. Also provided is a horizontal coating production line provided with the film surface flattening assembly.
