[0022] Reference Figure 1-2 A cutting assembly for a winding machine includes two mounting plates 1, one of which is equipped with a motor 2, a rotating shaft 3 is rotatably mounted between the two mounting plates 1, an output shaft of the motor 2 is connected to one end of the rotating shaft 3, a plurality of mounting cylinders 4 are arranged on the rotating shaft 3, and a cutting blade 5 is mounted on each mounting cylinder 4. When the motor 2 is running, the rotating shaft 3 is driven to rotate, and when the rotating shaft 3 is rotated, the mounting cylinder 4 and the cutting blade 5 can be driven to rotate, and the rotating cutting blade 5 is used to cut the non-woven fabric, and side plates 6 are fixed on the two mounting plates 1, and a top plate 7 is fixed between the two side plates 6;

[0023] The top plate 7 is provided with a plurality of sharpening components, which include a mounting frame 81, two openings 82, two brackets 83, two grinding blocks 84 and two springs 85. The mounting frame 81 is fixed to the bottom surface of the top plate 7, and the two openings 82 are both provided on the mounting frame 81. The two grinding blocks 84 are respectively slidably arranged in the two openings 82, and the side surfaces of the grinding blocks 84 fit with the inner surfaces of the openings 82.

Therefore, when the cutting blade 5 is rotating, the two grinding blocks 84 can grind the blade position of the cutting blade 5 to avoid passivation of the cutting blade 5, thereby ensuring the cutting effect of the cutting blade 5 on the non-woven fabric.

[0024] An absorption assembly is provided on one of the mounting plates 1, and the absorption assembly includes an air suction cylinder 91, a shaft 92, an air suction member 93, an air suction pipe 94 and a plurality of absorption covers 95.

When the rotating shaft 3 rotates, it can drive the mounting cylinder 4 and the cutting blade 5 to rotate, and the rotating cutting blade 5 is used to cut the non-woven fabric. For the sharpening assembly, under the elastic force of the two springs 85, the two grinding blocks 84 are always in contact with the blade position of the cutting blade 5. Therefore, during the rotation of the cutting blade 5, the two grinding blocks 84 can grind the blade position of the cutting blade 5 to avoid the passivation of the cutting blade 5, thereby ensuring the cutting effect of the cutting blade 5 on the non-woven fabric;

[0027] In addition, when the motor 2 drives the rotating shaft 3 to rotate, the rotating shaft 3 can also drive the shaft rod 92 to rotate.

Under the action of negative pressure, the suction pipe 94 can absorb the dust generated during the grinding process of the cutting blade 5 through the absorption cover 95, and finally the dust is discharged into the interior of the collection box by the suction member 93. Therefore, the setting of the collection component can collect the dust generated during the grinding process of the cutting blade 5.
