[0021] In this invention, the negative pressure dust collection assembly 15 further includes: a negative pressure pump 1509, disposed below the dust collection box 1502, with a negative pressure head of the negative pressure pump 1509 fixedly connected to a negative pressure pipe 1508; a filter port 1507, fixedly connected to the side of the dust collection box 1502 near the negative pressure pump 1509, with one side of the filter port 1507 fixedly connected to the side of the negative pressure pipe 1508 away from the negative pressure pump 1509, and the negative pressure pipe 1508 communicating with the dust collection box 1502.

[0022] In this invention, both sides of the dust collection box 1502 are fixedly connected to the fixing members 1501. A plurality of suction pipes 1505 are fixedly connected to the side of the dust collection box 1502 near the suction head 1506. The suction pipes 1505 are all fixedly connected to the bottom end of the suction head 1506. The top of the dust collection box 1502 is fixedly connected to the top of ...

[0023] In the negative pressure dust collection assembly 15, the dust scraper 1504 and the dust suction head 1506 work together to effectively remove dust, reduce fabric defect rate, make the fabric surface cleaner and smoother, and meet the production requirements of high-quality fabrics.

[0024] Reference Figures 1-4 In a preferred embodiment, a fixing frame 4 is fixedly connected to the outer side of a plurality of yarn guides 3, and a connecting frame 6 is fixedly connected to the outer side of a plurality of yarn feeders 5. A base frame 7 is provided below the connecting frame 6 and the fixing frame 4. The bottom ends of the connecting frame 6 and the fixing frame 4 are fixedly connected to the top end of the base frame 7. A lifting frame 8 is fixedly connected to the bottom end of the base frame 7. The knitting system 9 is disposed inside the lifting frame 8. A support frame 10 is fixedly connected to the bottom end of the lifting frame 8, and the top end of the support frame 10 is fixedly connected to the top end of the knitting system 9. A bottom plate 16 is fixedly connected to the bottom inner side of the support frame 10. A symmetrical frame 13 is fixedly connected to the top of the bottom plate 16. A support plate frame 14 is fixedly connected to the opposite side of the symmetrical frame 13. A winding roller 12 is movably connected to the opposite side of the symmetrical frame 13. Two connectors 11 are fixedly connected to the top of the support plate frame 14. The top of the support plate frame 14 is fixedly connected to the bottom of the support frame 10. The connectors 11 are all located inside the support frame 10. The opposite side of the connectors 11 is fixedly connected to the opposite side of the fixing member 1501.

[0025] Working Principle: The yarn is guided into the weaving system 9 by the yarn guide 3. The weaving system 9 interweaves and weaves the yarn into fabric according to the set weaving process. During the weaving process, the frame 1 and other structures provide stable support, ensuring stable and continuous weaving operations and continuous production of woven fabric. The woven fabric is gradually conveyed to the winding stage. Before the woven fabric is conveyed to the winding roller 12 for winding, the fabric surface passes over the dust scraper 1504. The dust scraper 1504 is connected and fixed to the dust collection box 1502 via the top frame 1503. The dust scraper 1504 contacts the fabric surface, and the relative motion generated by the fabric conveying (the fabric moves while the dust scraper 1504 remains relatively stationary) scrapes off the dust adhering to the fabric surface during weaving, causing the dust to detach from the fabric surface and fall into the area below the dust scraper 1504. When the pressure pump 1509 operates, it creates a negative pressure environment in the dust collection box 1502, suction pipe 1505, and suction head 1506 through the negative pressure pipe 1508 and filter port 1507. The dust scraped off is captured by the suction head 1506 under the action of negative pressure and transported to the dust collection box 1502 for storage through the suction pipe 1505. The two negative pressure dust collection components 15 act on both sides of the fabric, scraping and suctioning dust simultaneously to thoroughly remove dust from both sides of the fabric. The filter port 1507 separates the airflow and dust, ensuring that the dust remains in the dust collection box 1502. The airflow is discharged through the negative pressure pump 1509 to maintain the continuous and effective negative pressure adsorption. The fabric cleaned by the negative pressure dust collection components 15 continues to be conveyed to the take-up roller 12. The take-up roller 12 rotates and winds the clean fabric into a roll, ensuring that the fabric is wound flat and smoothly during the winding process.

[0026] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
