Description

Scraper mechanism, using method, coating machine and lithium battery production equipment Technical Field The application relates to the technical field of coating machines, in particular to a scraper mechanism, a using method, a coating machine and lithium battery production equipment. Background In lithium battery production equipment, a coating machine is core equipment for preparing a pole piece, and a prime coating process plays a key role in the thickness uniformity and the surface quality of the pole piece coating. The doctor blade serves as a core member of the primer unit, and the slurry coating accuracy is ensured by continuous blade coating. But scraper mechanism is when actual production uses, according to different customer's first coat production demand, needs high frequency tool changing, and the coating machine first coat scraper mechanism among the related art generally adopts manual tool changing's mode, and this not only leads to the tool changing inefficiency, influences the productivity, and the phenomenon that the scraper atress is uneven, compresses tightly the uniformity poor appears moreover easily, and then influences coating quality.
