[0039] The working principle and use process of the utility model are as follows: after one end of the rolled electrode sheet is placed above the transmission gear 24, the drive motor 21 is operated by an external control device. At this time, the shaft of the drive motor 21 will drive the multiple lower straightening rollers 23 to rotate counterclockwise to convey the rolled electrode sheet above, and during the conveying process, the rotation of the lower straightening roller 23 will be driven by the transmission gear 24 to make the upper straightening roller 22 rotate counterclockwise, so that the upper straightening roller 22 also conveys the rolled electrode sheet, and during the rotation and conveying process of the upper straightening roller 22 and the lower straightening roller 23, the rolled electrode sheet will be straightened;

At this time, the forward and reverse motor 352 and the motor on one side of the slitting component 35 are operated. The operation of the forward and reverse motor 352 will cause the threaded rod 353 at its output end to rotate, and then drive the slitting component 35 to slide inside the slitting chute 33. At this time, the motor sheet in strip shape is cut into small electrode sheets in cooperation with the rotation of the cutting disc 351.

[0041] After the electrode sheet is cut into a plurality of small electrode sheets, the small electrode sheets will fall into the collecting trough 4 under the action of gravity and will be gathered under the guidance of the guide cone block 5 .
