Yarn feeding wheel

The present invention relates to a yarn feeding wheel, in particular to a ceramic yarn feeding wheel which is formed by using a wave-shaped structure to be shifted from each other, so that the yarn feeding effect is smooth, the production is easy, and the yarn is not easily broken.

Pressing, the feeding yarn wheel is a component mounted on the circular knitting machine for feeding the yarn. It is conventionally known that the feeding yarn wheel is covered with a rubber or plastic wheel apron, and the yarn and the rubber ring on the surface of the yarn feeding wheel are used. Friction to transport the yarn. Since the wheel apron is constantly rubbed by the yarn, the surface of the wheel apron will become unsmooth and lead to poor yarn feeding, which will affect the quality of the fabric. Therefore, the rubber ring must be replaced regularly. However, due to the large number of yarn feeding wheels and winding yarns on each knitting machine, it is quite cumbersome and time-consuming to replace the yarn feeding wheel apron of a knitting machine, and the cost and cost will be incurred during downtime and replacement work. problem.

In order to solve the above problems, the related art has the patent of CN201068506Y, which discloses a durable yarn feeding wheel of a cross structure, comprising a yarn feeding yarn having a top wheel, a lower wheel and a numerically cross-mounted therebetween. The overall outline of the yarn feed bar is a right-angled triangle shape, wherein one of the horizontal right-angled edges or two ends thereof follows the radial direction of the upper or lower wheel and the lower or lower wheel of the upper wheel The upper side is fastened; the other vertical right side or two end points are fastened to the inner edge of the lower side of the upper wheel and the inner side of the upper side of the lower wheel; the horizontal right angle is installed and fastened. Yarn feed yarn on the side of the lower wheel and horizontal right angle The yarn feed yarns fastened to the lower side of the upper wheel are installed at the cross-phase setting.

The aforementioned prior art (No. CN201068506Y) is composed of a plurality of cross-mounted triangular yarn feeding yarns between the upper and lower discs, which is not only complicated in construction, but also the production of each triangular yarn feeding rod is time consuming, and The yarn feeding yarn rod is made of metal, and the uniformity of the quality and angle of each of the triangular yarn feeding yarn rods is quite difficult, resulting in an increase in cost.
