The cutting plate 4 is mounted on the conveyor 1 and corresponds to the mounting plate 3. The surface of the cutting plate 4 is flush with the surface of the conveyor belt on the conveyor 1. The first motor 6 is fixed on the mounting plate 3, and the shaft of the first motor 6 is fixedly connected to the connecting rod 7. A connecting hole 8 is opened at the center of the saw blade 5. The connecting rod 7 passes through the connecting holes 8 on the plurality of saw blades 5, and the plurality of saw blades 5 are evenly arranged on the connecting rod 7 at equal intervals and cooperate with the cutting plate 4. A rotating screw hole 13 is opened on the inner wall of the connecting hole 8, and the rotating screw hole 13 is threadedly connected with a rotating The screw 12 and the connecting rod 7 are provided with a limiting groove 14 which cooperates with the rotating screw 12. The rotating screw 12 rotates in the rotating screw hole 13 and can contact the inner wall at the bottom of the limiting groove 14. The rotating screw 12 rotates in the limiting groove 14. The cutting plate 4 is provided with a second motor 17 and a third motor 18. The shaft of the second motor 17 is provided with a conveying roller 20 which cooperates with the cutting plate 4 to facilitate the limiting of the paper towel raw material and the cutting by the saw blade 5. The shaft of the third motor 18 is provided with a limiting roller 19 which cooperates with the cutting plate 4 to facilitate the stable entry of the paper towel raw material after strip cutting into the conveyor belt of the conveyor 1. The limiting roller 19 and the conveying roller 20 are respectively arranged on both sides of the saw blade 5, and the limiting roller 19 corresponds to the conveyor 1.

[0021] The segmented cutting assembly includes a cylinder 9, a fixed plate 10 and a plurality of cutting blades 11. The cylinder 9 is fixed on the mounting frame 2. The piston rod of the cylinder 9 is fixedly connected to the fixed plate 10. The plurality of cutting blades 11 are evenly arranged on the fixed plate 10 and correspond to the conveyor belt on the conveyor 1. The fixed plate 10 is provided with a plurality of evenly arranged thread grooves 15. The cutting blade 11 is rotatably connected with a threaded rod 16. The threaded rod 16 can be rotatably connected to the cutting blade 11 through a bearing. The threaded rod 16 is threadedly connected to the thread groove 15. The number of the thread grooves 15 is greater than the number of the cutting blades 11.

[0022] Working principle: the saw blade 5 is sleeved on the connecting rod 7 through the connecting hole 8. The position of the saw blade 5 is adjusted according to production needs so that the distance between two adjacent saw blades 5 meets the width of the paper towel to be produced. The rotating screw 12 in the rotating screw hole 13 is forced to rotate the rotating screw 12 to the limit groove 14 on the connecting rod 7. The rotating screw 12 is continuously rotated to make it contact with the inner wall of the limit groove 14, so that the rotating screw 12 fixes the connecting rod 7 in the connecting hole 8, thereby fixing the saw blade 5 at this position of the connecting rod 7, which is convenient for adjusting the distance between two adjacent saw blades 5 to adapt to different Production requirements enhance practicality. According to the length and size requirements of the produced paper towels, the position of the cutting blade 11 on the fixing plate 10 is adjusted so that the spacing between two adjacent cutting blades 11 meets the length of the paper towels to be produced. The threaded rod 16 on the cutting blade 11 is rotated so that the threaded rod 16 is threadedly connected with the thread groove 15 to facilitate fixing the cutting blade 11 at this position.

It is suitable for different production requirements and further enhances practicality.

[0023] The second motor 17 works to drive the conveying roller 20 to rotate, and a long section of tissue paper material is conveyed to the saw blade 5. The first motor 6 works to drive the connecting rod 7 to rotate at high speed, so that the saw blade 5 on the connecting rod 7 rotates at high speed to cut the tissue paper material into a plurality of strips. The conveying roller 20 cooperates with the cutting plate 4 to press and level the tissue paper material, which is convenient for the saw blade 5 to cut better and prevent the tissue paper material from deviating during cutting and affecting the cutting effect, thereby improving the quality of the finished tissue paper. The third motor 18 works to drive the limiting roller 19 to rotate and roll on the tissue paper material after stripping and cooperate with the cutting plate 4 to facilitate the stable entry of the tissue paper material after stripping into the conveyor belt of the conveyor 1, thereby preventing the tissue paper material from being cut into strips. The cut strips of tissue paper are offset when entering the conveyor 1, and the limiting roller 19 further flattens the tissue paper, further improving the quality of the finished tissue paper. After the conveyor 1 works to transport the stripped tissue paper material for a distance, the cylinder 9 works to drive the mounting plate 3 to move downward, so that the several cutting blades 11 on the mounting plate 3 cut the tissue paper material on the conveyor belt into several small sections to complete the slitting of the tissue paper material. Finally, it is possible to adjust the distance between two adjacent saw blades 5 according to production needs, and cut the wider tissue paper material into multiple strips of required width through several saw blades 5, and then cut it into multiple small sections through several cutting blades 11, thereby improving the cutting efficiency and enhancing practicality.
