It is mainly used to guide and control the winding process of the wire to ensure that the wire maintains a stable path and tension during the winding process. In the automatic winding machine, the wire nozzle is usually made of hard materials, such as tungsten steel or ceramics. The shape and structure of the wire nozzle are reasonably designed to ensure its wear resistance and winding quality. The shape and structure of the wire nozzle is an important factor that directly affects the winding quality.

[0041] Specifically, the inner wall at one end of the outlet 23 is smoothly connected to the inner wall at one end of the first hole segment 221, the inner wall at the other end of the first hole segment 221 is smoothly connected to the inner wall at one end of the third hole segment 223, the inner wall at the other end of the third hole segment 223 is smoothly connected to the inner wall at one end of the second hole segment 222, and the inner wall at the other end of the second hole segment 222 is smoothly connected to the inner wall at one end of the inlet 21.
[0042] Specifically, the central axis of the first hole segment 221 , the central axis of the second hole segment 222 , and the central axis of the third hole segment 223 are on the same straight line.
[0043] In one embodiment, the wire outlet 23 is a structure of an arc-shaped outward-turned opening, and the wire inlet 21 is a structure of an arc-shaped outward-turned opening.
