[0002] During the warping and weaving process of the warp knitting machine, the yarn feeding order directly affects the quality of the woven fabric. The synchronous and orderly yarn feeding order can make the woven fabric have neat specifications and uniform density between the yarns. In the traditional yarn feeding process, the yarn is directly fed out from the yarn tube. At this time, the horizontal direction of the yarn is uneven, and it is easy to have uneven density between the yarns during the weaving process. The most common quality problem is that the gap is too large, which affects the qualified rate of the finished woven fabric, and a tension device is needed.

However, it is unable to monitor the tension of the yarn, unable to meet the special tension requirements during weaving, and cannot meet people's usage needs well. In view of the above situation, technical innovation is carried out on the basis of the existing tension device. Utility Model Content
