The fixed plate 301 serves as a support for the rotating drive structure and is used to be connected to the yarn winding machine; the driving motor 302 is used to drive the swing arm 304 to rotate; one end of the swing arm 304 is connected to the thread cutting robot to drive the thread cutting robot to rotate; the reducer 303 is used to reduce speed; the ventilation component 305 is used to replace part of the ventilation pipe so that the ventilation pipe will not twist at the rotating part. Specifically, the reducer 303 is arranged on the fixed plate 301, one end of the reducer 303 is connected to the driving motor 302, and the other end of the reducer 303 is connected to the swing arm 304. The driving motor 302 drives the swing arm 304 to rotate. The ventilation assembly 305 includes a fixed part 306 and a rotating part 307. The fixed part 306 is rotatably connected with the rotating part 307. A ventilation channel is arranged between the fixed part 306 and the rotating part 307 to allow the gas to flow from the fixed part 306 to the rotating part 307 or from the rotating part 307 to the fixed part 306. The above arrangement can avoid the ventilation pipe connected at both ends from being twisted, improve the reliability of the rotation drive mechanism, and extend the service life of the ventilation pipe.

[0028] like Figure 3 and Figure 4 As shown, as an implementation, the ventilation channel includes a first ventilation hole 308, a second ventilation hole 309 and a ventilation cavity 310, the first ventilation hole 308 is provided on the fixed member 306, the second ventilation hole 309 is provided on the rotating member 307, and the ventilation cavity 310 is formed between the fixed member 306 and the rotating member 307, and the ventilation cavity 310 is respectively connected with the first ventilation hole 308 and the second ventilation hole 309.
