Description

Yarn anti-winding device

The invention relates to a yarn guiding anti-wrap device, in particular to a mutual density relationship between a yarn guiding adjusting unit and a yarn feeding wheel, which automatically adjusts and changes according to the yarn feeding demand, and actively avoids the yarn from being greatly changed due to the tension. And entanglement.

As the variety of weaving yarns in circular knitting machines changes with each passing day, and the demand for fabric characteristics in the weaving market is becoming more and more demanding, the guiding and conveying operation of the yarn feeding device to the yarn becomes more and more important. A conventional technique for guiding the yarn feeding has a patent of GB1509309A, which discloses a yarn feeding wheel and a yarn dividing rod on one side of the yarn feeding wheel, and a yarn is subsequently wound around the yarn passing through a yarn guiding eye. The rod and the yarn feeding wheel are finally output through a yarn eye for quantitative or variable yarn feeding operation.

Although the prior art can reach the yarn feeding operation, there are still some defects. For example, when the conventional technology is in a large range of changes in the yarn demand, the role of the yarn dividing rod is insufficient. In particular, when the new functional yarn is woven, there is often a situation in which the yarn tension varies widely. At this time, if the yarn demand is drastically reduced, the yarn tension drops sharply, and the yarn feeding wheel is the same. The yarn feeding speed is sent to the yarn, which will inevitably cause the yarn to be loosened by the outer circumference of the yarn feeding wheel, which will lead to the entanglement of the yarn, so that the weaving operation will cause yarn entanglement problems, or it may be forced to interrupt the yarn grooming. Reconstruction, a non-ideal design. Furthermore, the yarn feeding wheel is wound around a belt, and since the width of the belt occupies a part of the area of the yarn feeding wheel, the operation of the yarn feeding wheel for winding the yarn is quite inconvenient (refer to Figs. 3 and 4). And the winding of the yarn on the yarn feeding wheel is restricted by the upper and lower positions of the yarn guiding eye, and the yarn can only be wound around the yarn feeding wheel due to the limitation of the yarn guiding eye. 2-3 turns, which makes the yarn slip with the yarn feeding wheel during the fast yarn feeding, which affects the yarn feeding stability, and the degree of the tightness of the yarn loops on the yarn feeding wheel cannot be adjusted according to the characteristics of the fabrics in the weaving market. , there is a lack of it; at the same time, because the frictional resistance between the yarn and the yarn feeding wheel will affect the yarn feeding speed and the yarn feeding amount, the surface friction relationship of the yarn on the yarn feeding roller is on the yarn surface. The glossiness will be depleted, which will affect the texture of the cloth weaving. Although the conventional technique can reduce the partial frictional resistance by the yarn dividing rod, the technical design scheme for actively reducing the frictional resistance has not yet been achieved, and there is also an improvement. Necessary. Therefore, how to solve the problem of the missing design of the yarn-splitting rod of the existing yarn feeding device is completely solved. It is the key direction that the industry should explore and break through.

Accordingly, the inventors of the present invention have developed and conceived their solutions in view of the fact that the use of the yarn feeding device is lacking in design and the fact that the structural design is not ideal, and it is hoped that a smooth operation of the knitting machine can be developed.
