After the pair of motors are fixedly installed on the left bearing seat, the motors are drivingly connected to the two rotating shafts on the left side. The slitting and cutting mechanism can be conveniently assembled and disassembled.

[0008] As the improvement, the positioning structure comprises a cylinder sleeve, a nut sleeve, a handle screw, a sawtooth clamping block and a rack groove; the cutting knife sleeve is fixedly connected to one end of the outer wall of the cylinder sleeve; a screw hole is reserved on the single side wall of the cylinder sleeve; the nut sleeve is integrally formed on the outer wall corresponding to the screw hole; the handle screw is threadedly connected into the nut sleeve and the screw hole; the handle screw is rotatably connected with the sawtooth clamping block at the tail end; the rack groove is formed on the rotating shaft side wall and extends from one end to the other end; and the sawtooth clamping block is in the rack groove and is engaged with the rack groove, and a gap is formed between the sawtooth clamping block and the inner wall of the cylinder sleeve at the screw hole.
