When sewing thick fabrics, a larger friction coefficient is formed between the upper thread and the fabric, and it is more difficult for the thread take-up rod to reel in the thread. Therefore, the upper thread tension should be adjusted to a larger value, otherwise the thread will easily float. When sewing thin and soft fabrics, the upper thread tension should be adjusted to a smaller value, otherwise it will easily shrink and wrinkle. In the traditional upper thread winding process, it is often necessary to adjust the tension of the winding device according to the tension of the upper thread to ensure the flatness and tightness of the upper thread.

[0003] However, traditional adjustment devices often have some problems, such as inconvenient adjustment, low precision, poor stability, etc., and the device is usually fixed, and it is impossible to change the position and tension of the tensioning wheel through the adjustment mechanism according to the needs of the surface line to achieve precise adjustment of the surface line tension. It is very inconvenient to use. Reference patent number: CN202021476847.4.
