The large belt cast coater is an 800mm long belt cast coater with vacuum suction cups and micrometer adjustable applicators. The large belt cast coater is designed for the production of long and thick films, with a unique drive system that produces smooth coatings on a wide range of materials. The large belt cast coater is designed for electrophoretic coating of various cylindrical cells such as the 18650 format.
The large-scale belt cast coater uses vacuum suction cups and oil-free Vacuum Pumps to adsorb and fix the substrate, so that the substrate is wrinkled during the coating process, so that the coating is more uniform and smooth, and also prevents the pollution of the substrate by oil stains in the Vacuum Pump. The width of the film can be controlled according to the width of the Film Applicator during the working process of the large belt cast coater, and the baffle in the middle of the scraper can move left and right, and when the baffle plate and the side of the scraper completely coincide, the width of the film can reach the limit. With the micron-level adjustable film maker, the film length can reach 800mm. Equipped with a unique automatic propulsion device, it can prepare smooth coatings on any material in the range of 250mm wide and 800mm long, which is a reliable tool for low-cost development and production of 18650 lithium battery electrode materials.
