[0002] Double-sided circular knitting machine, scientifically known as circular weft knitting machine or circular weft knitting machine, is particularly important in the textile field because of its large number of yarn feeding or looping paths, high speed, high output, fast pattern change, good fabric quality, few processes and strong product adaptability. It is used to produce semi-finished fabrics such as underwear or sportswear, sweatshirts, T-shirts, etc. that we wear daily.

[0003] Publication No. (CN219490307U) discloses a double-sided knitting circular machine with a yarn feeding guide structure, including a base, the top of the base is fixedly connected to the circular machine body, the top of the base is fixedly connected to the chassis, the inner cavity of the chassis is provided with an axial movement mechanism, the axial movement mechanism includes a driving motor, the output shaft of the driving motor is fixedly connected to a threaded rod, the surface of the threaded rod is sleeved with a threaded sleeve, and the surface of the threaded sleeve is fixedly connected to a limit rod. The utility model cooperates with the circular machine body, the chassis, the axial movement mechanism and the height adjustment mechanism, the axial movement mechanism drives the height adjustment mechanism to move axially, and the height adjustment mechanism drives the limit ring to adjust the upper and lower positions, so that the yarn can be guided and adjusted as needed, the operation is simple, and the guiding is flexible, so as to achieve a high practical effect, and solve the problem of low practicality of the existing device.

[0004] In the comparative document, the height of the limit ring is adjusted by a cam, but the adjustment accuracy of the cam is not high and precise guiding cannot be achieved.
