Description

Technical Field

[0001] The utility model relates to the technical field of loom equipment, in particular to a weft yarn traction device for a jet loom. Background Technique

[0002] A jet loom is a shuttleless loom that uses a jet of air to draw the weft yarn through the shed. Its working principle is to use air as the weft insertion medium, and the compressed air jet ejected generates frictional traction on the weft yarn to draw it, bringing the weft yarn through the shed, and achieving the purpose of weft insertion through the jet flow generated by the jet. This weft insertion method enables the loom to achieve high speed and high output. Among several shuttleless looms, the jet loom has the highest weaving speed. Due to the reasonable weft insertion method, high weft insertion rate, simple, safe operation, wide variety adaptability, low consumption of machine materials, high efficiency, high speed, and low noise, it has become one of the most promising new types of looms. When a jet loom is in use, a traction device is required to draw the weft yarn over.

[0003] At present, the weft yarn traction device on a jet loom installs the weft yarn bobbin by sleeving it on a thin rod. Although this installation method can quickly disassemble and replace the bobbin, it completely relies on the traction force to remove the weft yarn from the bobbin, and is easily limited by the traction speed. When the traction speed is too fast, the instantaneous tension on the weft yarn will become larger, easily breaking the weft yarn. Therefore, the traction efficiency of the weft yarn is not high.
