Description

Color change yarn

The invention relates to a color-changing yarn feeding wheel, in particular to a ceramic yarn feeding wheel which is formed by using a concave-convex structure and a mutual offset, so as to achieve a color-changing yarn feeding wheel which has a smooth yarn feeding effect, is easy to manufacture, and is not easy to be broken.

Pressing, the color changing yarn feeding wheel is a component mounted on the circular knitting machine for feeding the yarn. It is known that the color changing yarn feeding wheel is covered with a rubber or plastic wheel rubber ring, and the wheel on the surface of the yarn and the color changing yarn feeding wheel is used. The friction of the apron is used 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 yarns on the knitting machine and the number of yarns wound around each knitting machine, it is quite cumbersome and time-consuming to replace the color-changing yarn wheel apron of a knitting machine, and the downtime and replacement work time will bring benefits and The problem of cost.

In order to solve the above problems, the related art has a patent application of the mainland patent publication No. CN201068506Y, which discloses a cross-structured durable yarn feed wheel comprising a yarn support rod having an upper wheel and a lower wheel and a numerically cross-mounted therebetween, the yarn The overall contour of the wire support bar has a right-angled triangular shape, and one of the horizontal right-angled edges or two end points thereof follows the radial direction of the upper or lower wheel and the lower side of the upper wheel or the upper side of the lower wheel The installation is fastened; the other vertical right angle side or the two end points thereof are fastened to the inner edge of the lower side of the upper wheel and the inner edge of the upper side of the lower wheel; the horizontal right angle side is fastened to the lower wheel. The yarn support rod on the upper side of the disc is arranged to be interdigitated with the yarn support rod fastened to the lower side of the upper disc at a horizontal right angle side.

The aforementioned prior art (No. CN201068506Y) is composed of multiple upper and lower roulettes. The number of cross-mounted triangular yarn support rods is not only complicated in construction, but also the production of each triangular yarn support rod is time consuming, and the yarn support rod is made of metal, and the quality of each triangular yarn support rod And the uniformity of the angle control is quite difficult, resulting in cost increases. Moreover, the metal yarn support rod is wound by the yarn for a long time, especially when the knitting machine eats a large amount of yarn, the sharp shape of the yarn is cut with the cutting edge, and the triangular yarn support rod is often easily cut by the yarn. The burrs on the cutting rods then scrape the surface of the yarn, which is not ideal.

The related art is, for example, the continuation of the patent application No. CN201258393Y, which discloses a cross-structured yarn feeding wheel comprising an upper wheel, a lower wheel and a wheel neck, wherein the round neck is closed to the center of the upper wheel and the lower wheel. Short cylindrical shape, the wheel neck is integrally formed with the upper and lower wheel discs; the yarn support body is vertically cross-mounted between the upper and lower discs; the yarn support is thick The right-angled triangular support block is fastened to the wheel neck at its vertical right angle, and the middle ring of the wheel neck is exposed as a full circle of the wound yarn.

The above-mentioned prior art (No. CN201258393Y) is formed by interlacing the triangular yarn support bodies on the majority of the upper and lower discs, and the triangular yarn support body is of an upper and lower discontinuous type and is mutually staggered. The line may be caught in the gap between the support of each triangular yarn to cause the lack of yarn breakage, and there is also a need to improve it. Therefore, how to improve the lack of conventional yarn feeding wheels should be an important direction for the industry to solve and overcome.

Accordingly, the inventors of the present invention have developed the solution in view of the fact that the conventional yarn feed roller structure has disadvantages in its manufacture and use and its structural design is not ideal, and it is hoped that a production can be developed and sent.
