The current coater equipment has good coating effect, including the rack unwinding device, the traction device, the coating head and the discharge group. The coating head is placed on the frame from right to left, the discharge group is arranged above the coating head, the traction device includes the feed group tensioning group and the dust removal group, the dust removal group includes the left guide roller and the right guide roller, the left guide roller and the right guide roller are installed at left and right intervals, and the rubber roller is installed on the left side of the left guide roller and the right side of the right guide roller, The left and right guide rollers are close to each other. At present, the precision extrusion die for the coater is installed between the upper die and the lower die. The lower die is provided with a slurry inlet and a groove. The slurry inlet is connected to the groove through the lower die, and a number of precision scrapers are arranged in the groove. After the slurry enters the groove from the slurry inlet and passes through the precision scraper, the pressure is balanced through the scraping groove. After the slurry is extruded from the slit to the die mouth, the thickness of the horizontal coating is highly uniform, achieving the coating effect, Therefore, the problems of the transverse thickness of the coating, the middle thickness and the thickness of both sides are completely solved, and the precision coating head is more widely applicable to the viscosity and coating speed of the slurry. In the reverse coater device of the existing coater, the concave roller device and the transmission part are connected with the pressure roller part, the concave roller installation and transmission part are connected with the coating liquid part, the two introduction and extraction roller adjustment parts are located at the upper and lower sides of the pressure roller part, and the adjustable roller part is located below the sliding part of the slider. Now, the adhesion of the slurry and foil of the lithium battery pole is improved, the coater with lap joint or the coater with poor lap joint is improved, It will have a certain impact on the coating production efficiency. Since the cloth enters the coater device through the feeding conveying roller and prevents the film from adhering when passing through the left and right guide rollers, the adjustable coater includes an inclined piston and a storage tube, the lower end of the piston can be slidably arranged in the storage tube, and the left side of the storage tube is provided with a support frame scraper and an adjusting device nut, the scraper is fixed at the lower end of the adjusting nut, and the adjusting nut thread is installed on the support frame.
