[0002] In the textile production process, the use of large circular knitting machines can process fiber raw materials into yarns, which can greatly improve the processing efficiency of yarns and ensure the production quality of yarns. The flying flowers and dust generated during the operation of the large circular knitting machine not only affect the product quality, but may also pose a threat to the health of the operator. Therefore, dust removal and vacuuming of the large circular knitting machine is very important.

[0003] The prior art also has the following defects during use:

[0004] The multi-directional dust suction and dust removal device of the large circular knitting machine in the prior art adopts contact and non-contact dust removal methods for yarn dust removal. The traditional contact dust removal method scrapes off the flying flowers and dust on the surface of the yarn, which easily causes the problem of fuzzing on the surface of the yarn. In severe cases, when the scraping force is too large, it will cause the yarn to break during transmission, thereby affecting the production quality of the yarn by the large circular knitting machine. The traditional non-contact dust removal method uses air blowing to blow the flying flowers and dust on the surface of the yarn, and then collects the blown flying flowers and dust. Not only is the dust removal effect limited, but in the operation of the large circular knitting machine, in order to ensure the dust removal effect, it is also necessary to reduce the transmission speed of the yarn, thereby affecting the manufacturing efficiency of the yarn.

[0005] In view of this, we propose a multi-directional dust suction and dust removal device for a large circular knitting machine for textile use to solve the existing problems. Summary of the invention
