Description

Technical Field

[0001] The utility model relates to the technical field of flat knitting machines, in particular to a yarn feeder of a flat knitting machine. Background Art

[0002] A flat knitting machine is a double-needle plate latch needle weft knitting loom. Its triangle device is like a set of flat cams. The pins of the knitting needles can enter the grooves of the cams and move the triangles, forcing the knitting needles to make regular lifting and lowering movements in the needle grooves of the needle plate. Through the actions of the needle hooks and the needle tongues, the yarns can be woven into knitted fabrics. However, in the prior art, the existing flat knitting machines often need to transmit the yarns through a yarn feeding device during use.

[0003] For example, the Chinese utility model provides "a yarn feeding device in a knitting machine", and its announcement number is: CN214004964U. In the utility model, when making adjustments, the turning handle drives the first bevel gear to rotate, so that the first slide plate and the second slide plate threadedly sleeved on the double-threaded lead screw move at the same time, so that the first baffle plate and the second baffle plate move towards or away from each other according to the required width of the yarn. After the adjustment is completed, the turning handle is released, so that the yarn is placed between the first baffle plate and the second baffle plate and contacts the outer surface of the roller, so that the yarn is completely fed to the knitting machine under the rotation of the roller. In order to realize yarn feeding, a yarn feeding device with adjustable yarn width is added to a knitting machine, so that when the knitting machine uses yarn, the probability of yarn position deviation due to its large width during the yarn feeding process is reduced, the working efficiency of the knitting machine is improved, and the application scope of the yarn feeding device is further improved. However, the yarn feeding device of the knitting machine in the prior art cannot adjust the yarn feeding position as needed during actual use, which easily causes the yarn position deviation and dislocation. When the knitting machine receives the yarn, the knitting machine cannot operate normally due to the position deviation, thereby reducing the practicability of the device. Utility Model Content
