An air extraction pump 10 is fixedly assembled on the outer edge of the dust suction pipe 9. One end of the dust suction pipe 9 away from the first positioning ring 8 is fixedly connected to a sealing cover 11. An air outlet hole 13 is opened at the top of the sealing cover 11. Five inserting rods 14 are annularly distributed at the bottom of the sealing cover 11. A filter cotton board 15 is adhesively connected to the bottom of the sealing cover 11. A second positioning rod 16 is fixedly connected to the inner wall of the positioning frame 1. A second sliding ring 17 is slidably connected to the outer edge of the second positioning rod 16. A second positioning ring 18 is fixedly connected to the outer edge of the second sliding ring 17. A discharge pipe 19 is fixedly connected to the inner wall of the second positioning ring 18. An air extraction fan 20 is fixedly connected to the bottom of the discharge pipe 19. A cover plate 22 is fixedly connected to the bottom of the air extraction fan 20.

[0026] Refer to Figure 2 and Figure 3 , five jacks are annularly distributed at the top of the storage box 12, and the five inserting rods 14 are inserted into the inner walls of the five jacks, so that the sealing cover 11 can be stably positioned above the storage box 12, ensuring that it will not easily break away.

[0027] Refer to Figure 1 and Figure 4 , the top of the storage bin 21 is rotatably connected to the bottom of the sealing cover 11. A through hole is opened at the top of the cover plate 22, and the through hole corresponds to the bottom position of the air extraction fan 20, so that when the air extraction fan 20 operates, the debris generated during cutting can be absorbed into the inner cavity of the discharge pipe 19, and then fall through the through hole and be collected in the inner cavity of the storage bin 21.

[0028] Refer to Figure 2 - Figure 4 , one end of the bolt 7 close to the first positioning rod 5 fits with the outer edge of the first positioning rod 5. The inner wall diameter of the first sliding ring 6 is adapted to the outer edge diameter of the first positioning rod 5. A bolt 7 is also threadedly connected to the inner wall of the second sliding ring 17. One end of the bolt 7 close to the second positioning rod 16 fits tightly with the first sliding ring 6. The inner wall diameter of the second sliding ring 17 is adapted to the outer edge diameter of the second positioning rod 16, so that by loosening the bolt 7 and rotating the first sliding ring 6 and the second sliding ring 17, the positions of the dust suction pipe 9 and the discharge pipe 19 close to one end of the cutting knife 3 can be adjusted, thus facilitating the accurate collection of dust and debris.

[0030] Refer to Figure 1 - Figure 4 , both the discharge pipe 19 and the dust suction pipe 9 are made of flexible and bendable materials, so that the discharge pipe 19 and the dust suction pipe 9 can be bent arbitrarily to adjust their states, accurately align the feeding position after the cutting knife 3 cuts, and ensure that they will not be easily damaged when bent.

[0031] Working principle: When using this device, first lay the paper printed matter to be cut on the outer edge of the cutting roller 4, and then use the cutting knife 3 to cut its edge. During cutting, the air pump 10 can be driven to operate to absorb the dust generated during cutting into the inner wall of the dust suction pipe 9, and then collected into the inner cavity of the storage box 12. After being filtered by the filter cotton board 15, the gas is discharged to the outside through the air outlet 13. At the same time, the exhaust fan 20 can be driven to absorb the debris during cutting into the inner cavity of the discharge pipe 19, and then fall through the through hole and be collected into the inner cavity of the storage bin 21, improving the convenience of collection. Without manual operation, the bolts 7 can be loosened to rotate the first sliding ring 6 and the second sliding ring 17 to adjust the positions of one end of the dust suction pipe 9 and the discharge pipe 19 close to the cutting knife 3, so as to facilitate the accurate collection of dust and debris. Rotating the cover plate 22 can open it at the top of the storage bin 21 to remove the collected debris. Pulling the sealing cover 11 so that the insertion rod 14 is separated from the inner wall of the jack can remove the storage box 12, so as to facilitate the collection of the dust in the inner cavity of the storage box 12 and facilitate the removal of the filter cotton board 15 for cleaning and maintenance.
