[0002] A circular knitting machine refers to an industrial device used for knitting tubular fabrics. There are many yarn spindles on the warp beam of the circular knitting machine. According to the width of the knitted fabric and the width of the flat yarn, a specified number of warp yarns are used. Before the warp yarns enter the circular knitting machine, the warp yarns are crossed and opened by the heddle frame of the warp yarns. The weft shuttle makes a circular motion through the warp yarns in the crossed opening to knit into a tubular fabric.

The structural characteristics of the circular knitting machine are as follows: a low-center plane cam structure, breaking through the tradition, a brand-new transmission structure, realizing oil-free knitting, and safer food packaging; a broken weft detection system, magnetic signal transmission control, sensitive and reliable. By detecting the color difference between the weft tube and the weft yarn, once the weft yarn is almost used up and the yarn tube is exposed, the machine will automatically stop, reducing the production of defective products; an accurate servo lifting system, introducing position control technology into the knitting machinery, realizing weft compensation and rejecting shutdown.
