Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, in particular to an edge improvement device used in water-based coating films. Background Art

[0002] The surface coating technology of the coating machine is a technology that coats a new material on the surface of the product. Surface coating forms a film layer on the surface of the substrate. It is often used in the coating process of functional membranes. During the coating process, the coating machine transfers the water-based slurry to the substrate surface to form a wet coating film. Due to the flow characteristics of the slurry on the upper part of the membrane, the slurry is easy to gather on the side of the coating film to form droplets. When the wet coating film enters the drying oven for drying, the water-based slurry at the edge of the coating film will remain on the roller, causing the following problems:

[0003] 1. The residue on the roller surface will form dry material blocks. The accumulation of material blocks will cause the risk of curling, warping and scratching of the coating film during product production, as well as the generation of foreign matter.

[0004] 2. The external rollers need to be cleaned frequently, the space inside the oven is narrow, and the slurry blocks accumulated on the roller surface are difficult to clean thoroughly, which in turn affects production efficiency;

[0005] 4. Before the wet coated film enters the oven, the adsorption roller absorbs the slurry at the edge of the film surface, which is very easy to be blocked, causing the adsorption roller to lose its function, resulting in high repair costs and delayed production efficiency.

[0006] 5. Due to the adhesion of droplets, 2 cm of the edge of the coating film needs to be used as cutting scraps, which wastes slurry.

[0007] This is not conducive to the film coating process and the improvement of the quality of the finished product. Therefore, a device for improving the edge of a water-based coating film is provided. Utility Model Content
