The fixed ring 12 is used to evenly wind the yarn to the outside of the take-up roller 8, thereby ensuring the neatness of the yarn when it is wound.

[0023] An L-shaped plate 19 is fixedly connected to the top of the vertical plate 2 on the side away from the take-up roller 8, and a speed motor 20 is fixedly installed on the inner side of the L-shaped plate 19.
