Weft insertion yarn guide system of computerized flat knitting machine

Abstract

The invention discloses a weft insertion yarn guide system of a computerized flat knitting machine, and relates to the technical field of auxiliary components of the computerized flat knitting machine. The system comprises a support, an active yarn feeding device, a weft insertion yarn rebounding device, a weft insertion yarn guide device and a weft insertion yarn nozzle; the active yarn feeding device and the weft insertion yarn rebounding device are arranged on the support; the active yarn feeding device is located on the upper side of the weft insertion yarn rebounding device; the weft insertion yarn guide device is arranged between the active yarn feeding device and the weft insertion yarn rebounding device; the weft insertion yarn nozzle is arranged on one side of the support; and yarn in the active yarn feeding device sequentially penetrates through the weft insertion yarn guide device and the weft insertion yarn rebounding device and then enters the weft insertion yarn nozzle. Sliding friction of yarn in the moving process can be changed into rolling friction, so that friction force is reduced; and secondly, the yarn feeding direction can be changed, so that weft insertion yarns are bent more slightly before and after passing through the yarn nozzle, the weft insertion yarns are guided inwards more stably, and the damage is reduced.

Description

technical field [0001] The invention relates to the technical field of auxiliary components of a computerized flat knitting machine, in particular to a weft-inserted yarn guiding system of a computerized flat knitting machine. Background technique [0002] The computerized flat knitting machine itself is equipped with multiple yarn guide and yarn feeding devices. When knitting, the yarn needs to be directly drawn out from the yarn disc to the yarn pretension adjustment device to adjust the tension. The device enters the yarn clamping device, and enters the yarn guide device after exiting the yarn clamping device. The yarn is guided into the yarn feeder by the spring and the yarn guide ceramic ring in the yarn guide device to wait for machine weaving. [0003] The above-mentioned yarn guiding devices are not comprehensive, but the yarn guiding paths of existing yarn guiding devices on the market tend to be the same. In the traditional way, the weft-inserted yarn also needs t...

AI Technical Summary

Problems solved by technology

During the movement of the weft-inserted yarn from the yarn mouth to the fabric, the weft-inserted yarn passes through a large bending angle. For the weft-inserted yarn with a large flexural modulus, it will cause greater damage to the weft-inserted yarn itself after passing through the yarn mouth. Large damage, not up to the quality of the fabric
