Circular knitting machines use yarn guiding mechanism to introduce yarn into the yarn feeding device, and then use the yarn feeding wheel and yarn guiding rod of the yarn feeding device to carry out subsequent quantitative or variable yarn feeding operations. As the types of knitting yarns of the knitting machine change with each passing day Moreover, the demand for cloth characteristics in the weaving market is becoming more and more intense, making the yarn feeding device's guiding and conveying operation of the yarn more important. According to the press, it is known that the yarn feeding device with a quantitative or variable yarn feeding function is mainly composed of a yarn feeding device body, a collective or individual drive mechanism, a variable yarn feeding wheel or a fixed yarn feeding wheel, a yarn guiding unit, and a yarn guiding device. The yarn feeding device consists of a frame and a parking detection arm for entering and exiting the yarn. The system of the yarn feeding device is screwed to the creel ring on the circular knitting machine by a screw on the rear end of the body, and the yarn guide unit is combined with a group of Or a plurality of sets of yarn guides are provided on the body of the yarn feeding device to cooperate with the yarn guide unit to guide the yarn into the variable-quantity yarn feeding wheel.

When the yarn guides on the yarn guide are repeatedly wound and threaded, the yarn feeding device is arranged on a circular knitting machine in a circular array. Generally, for efficient use of space, the space between adjacent yarn feeding devices The available spacing is not large, so that the yarn feeding device The operating space is very narrow, so it is difficult and time-consuming to wind the yarn, and when the yarn breaks and stops, it is more difficult for the yarn to quickly complete the winding and repairing, which makes the time for repairing or re-threading longer. Therefore, the configuration of the yarn feeding device and the space of the yarn winding arrangement of the yarn feeding device seem to be quite inconsistent with the requirements of operation efficiency. In addition, the aforementioned yarn needs to be wound back and forth from the front and back ends of the yarn feeding device, which makes the winding process more complicated and time consuming, which is not the ideal winding design; It is necessary to break through the structure and operation of the whole yarn.

Moreover, the yarn guide eye of the conventional yarn feeding device is a penetrating type yarn guide eye. When drawing the yarn, the yarn must be drawn in from one side and drawn out at the other side. Therefore, the trouble of drawing the yarn needs to be improved.
