Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, in particular to a diaphragm coating anti-material throwing device. Background Art

[0002] In the production process of lithium battery separators, it is usually necessary to coat the surface of the separator (diaphragm) with a slurry to increase its performance.

[0003] The existing coating device is to scrape the material on the plate roller by setting scrapers at the upper and lower ends of the inner side of the material box, so that the liquid material covers the plate roller, and then the liquid material is coated on the isolation membrane by the plate roller. However, no sealing structure is provided on both sides of the existing material box. During the operation of the coating device, due to the effect of centrifugal force, the two sides of the plate roller are prone to material throwing. If the liquid material is thrown onto the isolation membrane, on the one hand, it affects the performance of the isolation membrane, and on the other hand, it may also affect the thickness of the isolation membrane. The existing solution is to use foam for isolation, but the isolation effect of the foam is poor, and the foam is easily soaked and thinned, and needs to be replaced frequently.
