The sliding friction between the cam and the pull piece of the existing reciprocating cam mechanism is large in change of reciprocating reversing speed and large in inertia, so that the cam is large in abrasion at two ends; the flatness of the two sides of the large-diameter monofilament is not good during molding. The single wire coiling tension control mechanism of the existing equipment is a pure mechanical mechanism; the accuracy of the tension value is poor, and the fatigue life of the spring in the mechanism is short.
