When the yarn layer is reduced, the inclined ring descends, the switch is switched on, and the motor drives the yarn storage cylinder to rotate to wind yarns; when the yarn reaches a certain amount, the inclined ring is lifted, the switch is switched off, and the yarn storage barrel stops rotating, so that a certain amount of yarn layers are always kept on the yarn storage barrel, the yarn unwinding conditions are consistent, the yarn tension is uniform, and the yarn feeding is stable.
When the knitting machine is used for knitting, the position of the density triangle can be changed in the working process, so that the phenomenon that the feed length of the knitting needles is inconsistent can be caused, the density of the fabric is inconsistent due to the inconsistent feed length, and the integral quality of the fabric is inconsistent. Therefore, a yarn measuring device is needed to monitor the yarn feeding length during yarn feeding, so that the tension in the yarn feeding process is constant, each piece of fabric is ensured to meet the process requirements, and the fabric quality is greatly improved. However, the existing yarn storage device is not provided with a yarn measuring device, and the yarn measuring device needs to be additionally installed, and the yarn measuring mode of the yarn measuring device is contact type yarn measuring. The contact type yarn measuring device has certain influence on the tension of the yarn, and particularly has different influence on the tension of the yarn due to sudden acceleration change when the yarn measuring device starts and stops.
