A wire guide structure is provided on the circumferential side of the wire guide body.

[0032] The wire guide body of the utility model can rotate independently, and the bearings can drive the respective rotating bodies respectively, and the rotation speed of the rotating body will not be affected because there is only one wire strip on the rotating wire guide.

[0033] The rotating body of the utility model is assembled with the inner ring of the bearing. Under this design, the load required to be driven is reduced, and at the same time, the rotating body drives the inner ring of the bearing to rotate when rotating, which can extend the service life of the bearing.

[0034] In some embodiments, the rotary wire guide comprises two wire guide bodies and two bearings, one bearing drives one wire guide body to rotate, and the two wire guide bodies rotate independently of each other. The axis of the bearing is parallel to the axis of the wire guide body, and the two bearings are arranged between the two wire guide bodies along their own axis direction, or the two wire guide bodies are arranged between the two bearings along their own axis direction. The wire guide body in this implementation case is a wire guide body.

[0035] Specifically, a pin is fixed on the inner ring of the bearing, a bushing is connected to the pin, one end of the pin is fixedly connected to the inner ring of the bearing, the other end of the pin is fixedly connected to the bushing, and the wire guide is sleeved on the outside of the pin and fixedly connected to the bushing. The inner ring of the bearing rotates to drive the pin and the bushing to rotate together, thereby driving the wire guide to rotate synchronously. A refueling port is provided on the bushing, and the refueling port passes through the bushing. Lubricating oil can enter the bearing through the refueling port to lubricate the bearing, thereby extending the service life of the bearing.

[0036] In some embodiments, the rotary wire guide further comprises a connecting seat, the two wire guide bodies are symmetrically arranged on both sides of the connecting seat, and the outer ring of the bearing is fixed on the connecting seat.

[0037] In some embodiments, the wire guide structure includes at least one annular groove formed on the surface of the wire guide body, and the annular groove has a smooth groove wall to reduce the friction between the wire and the annular groove or reduce the wear on the wire. Since at least two wire guide bodies are arranged on the wire guide, in order to prevent multiple wires from being entangled when multiple wire guide bodies work simultaneously, the side of the wire guide structure is provided with an anti-wire entanglement structure, and the anti-wire entanglement structure includes a shield arranged between the connecting seat and the wire guide body, and the wire guide body partially extends into the inside of the shield to prevent the wire from being entangled in the gap between the connecting seat and the wire guide body.
