[0002] Cotton yarn is made from cotton fibers through a spinning process, and is called cotton yarn after the twisting process; according to different spinning processes, it can be divided into combed yarn and combed yarn; carded yarn: yarn spun from cotton fibers through an ordinary spinning system; combed yarn: yarn spun from cotton fibers through a combed spinning system.

[0003] The cotton yarn needs to be stretched during the textile production process, but the existing stretching auxiliary device of the spinning frame cannot stretch the cotton yarn as needed, which affects the use effect of the spinning frame. At the same time, the fixing of the cotton yarn is very inconvenient, which affects the use of the spinning frame.

[0004] For example, the authorization announcement number CN 217324449 U discloses a fine yarn drafting device for cotton yarn production, including a frame, one side of the frame is internally connected to a first drafting rod. The utility model, when the spinning is drafted, the spinning is passed around the second drafting rod, the guide rod and the first drafting rod, the first drafting rod is driven to rotate by the motor, the first drafting rod drives the first gear to rotate, the first gear drives the second gear to rotate through the toothed belt, the second gear drives the second drafting rod to rotate through the speed change mechanism, and the outer diameter of the second drafting rod is smaller than the outer diameter of the first drafting rod, so that under normal conditions, the linear speed of the second drafting rod is smaller than the linear speed of the first drafting rod, so that the spinning and the second drafting rod are relatively slid, so that the spinning is in a tensioned state, and the spinning is drafted, and the linear speed difference between the second drafting rod and the first drafting rod can be adjusted by the speed change mechanism, and the drafting force can be adjusted according to the type of spinning, so as to avoid excessive drafting force causing the spinning to break easily.
