as shown in figure 1, the transfer coating machine for the multi-stripe pole pieces comprises a coating roller 1, a corresponding scraper roller 2 is arranged above the coating roller 1, a bottom plate 3 which is obliquely and upwards arranged is arranged on the feeding side of the coating roller 1, and the bottom plate 3 is connected with the coating roller 1 in a sealing mode. N side baffles 4 which can be abutted to the outer surfaces of the coating roller 3 and the scraper roller 2 and are movably connected with the coating roller 3 and the scraper roller 2 are sequentially arranged on the bottom plate 3 from front to back at intervals, and N is an even number greater than 2; every two side baffles 4 from front to back are sequentially in sealing fit with the bottom plate 3, the coating roller 1 and the scraper roller 2 to form N/2 independent hoppers 5 which are arranged at intervals, N/2 independent hoppers 5 for loading slurry correspond to N/2 coating areas 7 on the discharge side of the coating roller 1 one by one, and the N/2 coating areas 7 and a blank area between every two adjacent coating areas 7 form a plurality of corrugated pole pieces together.
Specifically, a first independent hopper 5 is formed by sealing and matching a first side baffle 4 and a second side baffle 4 from front to back with a base plate 3, a coating roller 1 and a scraper roller 2; and a third side baffle 4 and a fourth side baffle 4 are in sealing fit with the bottom plate 3, the coating roller 1 and the scraper roller 2 to form a second independent hopper 5. As shown in fig. 3, the thick lines are the sealed joints between the side dams 4 and the base plate 3, the coating roller 1 and the doctor roller 2.
