When in use, first turn on the motor according to the width of the pole piece, rotate the first screw rod to drive the sliding baffle, adjust the distance between the sliding baffle and the fixed baffle, and at the same time, pass the pole piece through the lower end of the limit rod and the upper end of the pressure rod in turn, rotate the second screw rod, adjust the distance between the blades, and then rotate the roller and the cutting shaft to start the pole piece slitting operation.

[0004] In the above utility model, a large amount of metal chips will be generated when the blade cuts the pole pieces, and there is no collection structure, which increases the workload of subsequent cleaning.
