Description

Yarn feeding device of flat knitting machine

Technical Field

The utility model belongs to the technical field of flat knitting machines, and particularly relates to a yarn feeding device of a flat knitting machine.

Background

A flat knitting machine is used as a knitting machine for knitting yarn clothing. During operation, the yarn sequentially passes through the creel, the yarn feeder and the take-up frame of the flat knitting machine and then enters the knitting mechanism for knitting. Since yarn garments woven by flat knitting machines typically have different colored patterns, each different colored pattern corresponds to a plurality of colored yarns. In order to provide a certain degree of tension to the yarn during the knitting process, the bobbins are typically placed on a frame and the tension is adjusted through the creels.

In order to weave yarn clothes with color mixing effect, the existing flat knitting machine is used for weaving after threading two or more yarns with different colors into one yarn nozzle, or twisting and mixing two or more yarns with different colors before weaving, so as to achieve the color mixing effect. However, the former method may have an asynchronous condition due to uncontrollable yarn feeding speeds of various yarns, and the latter method has loose yarns during conveying and uneven twisting effects due to uncontrollable yarn tension, and both methods can lead to a woven fabric pattern with great randomness and uneven or unclear shaping.
