when the winding angle is changed in the unwinding process, the winding angle can be sensed by the rotating member 12 and output through the measuring element 13, and then adjustment can be carried out at any time, so that the yarn can be unwound according to the original winding track, the pulling and retraction of the yarn are avoided, the basic stability of the tension of the yarn is ensured, and the accurate unwinding is realized.

In a preferred embodiment, as the unwinding process progresses, the diameter of the reel 3 wound with the yarn changes, and the change of the diameter of the reel 3 is measured by an automatic measuring device, so that the reel is adjusted to move along the x axis, and the yarn section between the second guide 122 and the reel 3 is always parallel to the yz plane, thereby further ensuring that the yarn is unwound from the reel 3 without being pulled. Wherein, the automatic measuring device can select tools such as a distance sensor and the like which can carry out measurement.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms, and any person skilled in the art may use the above-mentioned technical contents to change or modify the equivalent embodiment into equivalent changes and apply to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical matters of the present invention will still fall within the protection scope of the technical solution of the present invention.
