[0002] A circular knitting machine is a device used to produce tubular or flat knitted fabrics. It interweaves yarn into a mesh structure through continuous cyclic action. The yarn guide frame is an important component of the circular knitting machine. Its main function is to guide and tension the yarn to ensure that the yarn can be evenly supplied to the knitting needles.

[0003] During the use of the yarn guide frame of the existing circular knitting machine, when the yarn runs on the yarn guide frame, some dust and impurities are often inevitably attached to its surface. These dusts enter the knitting process with the movement of the yarn, and eventually affect the overall appearance and texture of the fabric. In addition to the influence of dust and impurities, the yarn may also produce burrs due to friction and other reasons during the production and transportation process. The burrs will be entangled with other yarns during the knitting process, causing broken threads, skipped threads, etc., affecting the continuity and stability of the knitting. At the same time, the burrs may also form small bumps or protrusions on the surface of the fabric, affecting the overall flatness and aesthetics of the fabric.
