The circular knitting machine has the advantages of high loop forming system (called yarn feeding path number or loop forming path number in enterprises for short) quantity, high rotating speed, high yield, fast pattern change, good fabric quality, few working procedures and strong product adaptability, so the circular knitting machine is developed quickly.

The cam of the circular knitting machine is also called a gorgon and a water caltrop. According to different requirements of circular knitting machines for knitting varieties, a triangular groove of a circular knitting machine is used for controlling a knitting needle and a sinker to do reciprocating motion in a needle cylinder groove. Therefore, the geometric parameters of the grooves of the circular knitting machine cam and the resistance in the track formed by the grooves are important parameters for judging the quality of the circular knitting machine cam.

At present, the grooves on the circular knitting machine cam are generally detected in a manual detection mode to detect geometric parameters and detect resistance in a track formed by the grooves, but due to manual detection, the circular knitting machine cam detection device is poor in precision, low in detection speed, large in workload, low in automation degree and low in production efficiency, the quality of the detected circular knitting machine cam is uneven, and the stability of the quality of the circular knitting machine cam is not facilitated.
