Yarn leading device for flat knitting machine

Abstract

The invention relates to a yarn leading device for a flat knitting machine. The yarn leading device comprises bearings, roller wheels, a bracket I, a bracket II and pins; a bearing is mounted in each roller wheel; the roller wheels are respectively mounted on the two ends of each of the bracket I and the bracket II; the bracket I, roller wheels and the bracket II are fixedly riveted by the pins; the bracket I and the bracket II are fixedly arranged on a yarn nozzle of the flat knitting machine through fixing holes; identical concave circular structures used for respectively surrounding the roller wheels are arranged on the two ends of each of the bracket I and the bracket II; the concave circular structures on the two ends of each of the bracket I and the bracket II are combined with the corresponding roller wheels precisely, and yarns cannot be wound in the roller wheels; a U-shaped smooth yarn guiding slot is designed on each roller wheel, and is finely polished and cannot break the yarns; yarns reaches a faller needle of the flat knitting machine via the roller wheels and a yarn nozzle yarn leading port, so that the yarn leading function is realized. According to the yarn leading device for the flat knitting machine, the roller wheels and the bearings are utilized to carry out rolling-type yarn leading, the yarn leading device is more convenient to use and cannot break the yarns, and the traditional structural defect of a ceramic ring used for leading yarns in a sliding manner is changed.

Description

technical field [0001] The invention relates to a flat knitting machine, in particular to a lead wire device of the flat knitting machine. Background technique [0002] The lead-in devices of traditional flat knitting machines are all made of ceramic rings. There is sliding friction between the thread and the ceramic ring. Long-term use of the yarn will grind the ceramic ring into gaps, causing problems such as easy thread breakage, machine alarms, etc., and low labor efficiency. , the present invention discusses changing the sliding friction between the wire and the ceramic ring into rolling friction, changing the defect that the worn wire is easy to break. Contents of the invention [0003] The purpose of the present invention is to provide a wire-leading device for a flat knitting machine that has rolling friction, is not easy to break, has higher efficiency, and is more durable. [0004] A kind of lead wire device of flat knitting machine comprises bearing, roller, su...
