The working process of the frame is to drive the adjustment of the upper and lower positions of the baffle plate 4 and the platform 5 through the adjustment of the screw 3. The screw 3 can realize precise micro-feeding, so that the main transmission placed on the platform 5 can be controlled more accurately. The upper and lower positions of the wire storage device of the system ensure that the horizontal position of the wire nozzle 16 is in the same plane as the center of the circle of the wound traveler core. Thereby helping to ensure the precision of steel wire winding.

The movement mode of the traveler winding is to drive the annular small-diameter traveler core 18 to rotate, and to drive the steel wire turntable and the steel wire nozzle to perform cross motion around the traveler core. This winding process requires the assembly and disassembly of the traveler core. The gear train of the notched main transmission device can satisfy the winding. It is only necessary to rotate the notched gear at the end and the wire storage reel so that the notch direction of the sixth gear 11 is consistent with the notch direction of the lower platform, and the traveler core can be put in and out along the notch direction. And there is no need to repeatedly install and disassemble the gear train. The notch-type main transmission device is very convenient to assemble and disassemble the workpiece to be wound, and can greatly improve the winding efficiency.

The positioning, clamping and rotating device of the traveler belongs to the clamping transmission scheme. The clamping transmission scheme relies on mechanical claws to hold the traveler, and relies on the guidance of the steel plate to alternately hold the traveler around the center of the traveler to provide driving force. The motor drives the steel belt to rotate, and the mechanical claw on the rigid belt enters the grasping stage sequentially with the guidance of the guide steel plate. During the grasping process of the mechanical claw, it plays two roles of vertical fixation and providing rotational force. When the mechanical claw leaves the steel plate , the torsion spring in the mechanical claw 71 will automatically open the mechanical claw, and only when entering between the lower guide steel plate 73 and the upper guide steel plate 74, the mechanical claw 71 is closed and clamps the traveler. The gripping force of the mechanical claw can act on the steel plate through the cylinder to provide sufficient pressing force so that the mechanical claw does not slip, and the transmission steel belt can ensure sufficient transmission force by the central roller 19 playing the role of the tension wheel. This solution is not easy to lose the ring, and can ensure high transmission accuracy.
