[0021] By controlling the cylinder 1 32 to make the mounting frame 33 move downward, the knife disc 37 moves downward and contacts the non-woven fabric 5, and then the motor 38 is started to make the connecting shaft 36 drive the knife disc 37 to rotate, so that the knife disc 37 can cut the non-woven fabric 5, and at the same time, the cleaning member 39 can clean the outer surface of the knife disc 37, so that the cut materials on the surface of the knife disc 37 can be cleaned to avoid the cut materials adhering to the knife disc 37 affecting the subsequent cutting work;

[0022] By controlling the cylinder 2 34 , the movable seat 35 can be moved horizontally, so that the horizontal position of the knife disc 37 can be changed, so that the cutting position of the knife disc 37 on the non-woven fabric 5 can be adjusted, thereby meeting the cutting requirements of different positions of the non-woven fabric 5 .

[0023] The connecting shaft 36 includes a sleeve shaft 361, which is rotatably connected to one end of the movable seat 35, one end of the sleeve shaft 361 is fixedly connected to the cutter disc 37, and the other end of the sleeve shaft 361 is slidably connected to the plug shaft 362, and the end of the plug shaft 362 away from the sleeve shaft 361 is fixedly connected to the output shaft of the motor 38, and the outer side of the plug shaft 362 is fixedly connected to the limit bar 363, and the limit bar 363 is slidably connected to the inner wall of the sleeve shaft 361.
