[0002] In the large-diameter (0.2-0.5mm) monofilament production process, it is necessary to wind the large-diameter monofilament into a coil of a certain shape. The winding device in the prior art is too simple and requires a lot of manpower; the maintenance of the device is complicated. ; Unable to monitor the running status of the equipment in real time

[0003] The existing large-diameter monofilament coiling equipment adopts a reciprocating cam mechanism. The characteristic of the reciprocating cam mechanism is that the rotation speed of the main shaft and the rotation speed of the reciprocating cam (forming winding ratio) are constant; The linear speed is different from the reciprocating speed (that is, the forming winding ratio is different); therefore, it is necessary to replace the transmission device when adjusting the type of monofilament products and forming; due to the large number of spindles in monofilament equipment, the failure rate is relatively high and the equipment The maintenance is complex and cumbersome, and the cost is high; the flexibility of the equipment is poor, and it cannot meet the flexible production requirements of the factory

In the existing reciprocating cam mechanism, there is sliding friction between the cam and the puller, and the change in the reciprocating reversing speed is relatively large, and the inertia is relatively large, so the wear of the cam at both ends is relatively large; resulting in uneven forming flatness on both sides of the large-diameter monofilament during molding. good

The existing equipment monofilament coiling tension control mechanism only uses a purely mechanical mechanism; the accuracy of adjusting the tension value is poor, and the fatigue life of the spring in the mechanism is relatively low
