[0027] The upper end of the base 1 is fixedly connected to a symmetrically distributed first mounting plate 2 and a second mounting plate 3, and the interior of the second mounting plate 3 is rotatably connected to a rotating block 4. A cutting assembly 5 for cutting the workpiece is arranged between the first mounting plate 2 and the second mounting plate 3, and the cutting assembly 5 includes a mounting block 51 bolted to the inside of the first mounting plate 2, and a rotating rod 52 is rotatably connected to the side wall of the mounting block 51. A plurality of evenly distributed threaded holes are provided on the side wall of the rotating rod 52, and the plurality of threaded holes are threadedly connected to the bolts of the fixed mounting shell 54. One end of the rotating rod 52 is fixedly connected to an insertion rod 53, and the insertion rod 53 is slidably connected to the rotating block 4. A plurality of evenly distributed mounting shells 54 are bolted to the outside of the rotating rod 52, and a cutting knife 55 is fixedly connected to the side wall of the mounting shell 54, and the cutting knife 55 is slidably connected to the rotating rod 52.

[0028] Exemplarily, the second mounting plate 3 is used to install the rotating block 4, and the insertion rod 53 is inserted into the interior of the rotating block 4 and connected to the rotating block 4, so that the rotating block 4 drives the rotating rod 52 to rotate through the insertion rod 53. The multiple threaded holes on the rotating rod 52 are convenient for adjusting the position of the mounting shell 54 and the cutting knife 55 to cut the non-woven fabric at different widths. When the rotating rod 52 rotates, it drives the cutting knife 55 to rotate, and the cutting knife 55 cuts the non-woven fabric. The first mounting plate 2 is used to install the mounting block 51.

[0029] A first motor 6 is provided on the side wall of the second mounting plate 3 , and an output shaft of the first motor 6 is fixedly connected to the rotating block 4 .

[0030] Exemplarily, the first motor 6 drives the rotating block 4 to rotate.

[0031] The upper end of the base 1 is provided with a dust removal assembly for collecting dust generated during cutting. The dust removal assembly includes two support columns 9 fixedly mounted on the upper ends of the first mounting plate 2 and the second mounting plate 3 respectively. The interiors of the two support columns 9 are commonly fixedly connected with an air suction hood 10. The upper end of the air suction hood 10 is fixedly connected with a plurality of evenly distributed connecting pipes 11. The upper ends of the plurality of connecting pipes 11 are all fixedly connected with a hollow block 12. A bent pipe 13 is fixedly connected to the side wall of the hollow block 12.

[0032] For example, when the non-woven fabric is cut, dust is generated.

Through the negative pressure of the air, the suction hood 10 draws the air on the upper end of the non-woven fabric into the interior of the suction hood 10. The connecting pipe 11 transports the airflow. The hollow block 12 facilitates the collection of the airflow and discharges it into the interior of the bend 13. The limiting ring 14 supports the collecting shell 15. The airflow enters the interior of the collecting shell 15. The filter plate 16 filters the dust in the airflow. After the fan stops, most of the dust falls into the interior of the collecting shell 15. The limiting plate 18 limits the collecting shell 15. After a period of use, the bend 13 and the external tube 17 are removed, and the collecting shell 15 is taken out and cleaned.

The multiple threaded holes on the rotating rod 52 are convenient for adjusting the position of the mounting shell 54 and the cutting knife 55 to cut the non-woven fabric of different widths. When the rotating rod 52 rotates, it drives the cutting knife 55 to rotate, and the cutting knife 55 cuts the non-woven fabric. The first mounting plate 2 is used to install the mounting block 51.

[0034] The two corresponding fixed plates 81 are internally connected to a bidirectional screw rod 82 for rotation, and the second motor 83 drives the bidirectional screw rod 82 to rotate. A threaded motion occurs between the bidirectional screw rod 82 and the movable frame 84, driving the movable frame 84 to move. The movable frame 84 slides on the outside of the base 1, and the base 1 limits the movable frame 84. The movable frame 84 limits non-woven fabrics of different widths. The lifting frame 85 descends under the tension of the tension spring 86 to adjust the tension of the non-woven fabric to prevent the non-woven fabric from loosening during processing and affecting the cutting effect. The roller 7 facilitates the movement of the non-woven fabric on the upper end of the base 1;

[0035] When the non-woven fabric is cut, dust is generated. The upper end of the external pipe 17 is fixedly connected to a fan, and the fan draws out the air inside the external pipe 17. Through the negative air pressure, the suction hood 10 draws the air on the upper end of the non-woven fabric into the interior of the suction hood 10. The connecting pipe 11 transports the airflow.

After a period of use, the curved pipe 13 and the external pipe 17 are removed, and the collecting shell 15 is taken out and cleaned.
