Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a yarn feeder of an air jet loom. Background Art

[0002] Air jet loom is a shuttleless loom that uses jet airflow to pull the weft yarn through the shed. The working principle is to use air as the weft insertion medium, and use the ejected compressed airflow to generate friction traction on the weft yarn to pull the weft yarn through the shed. The purpose of weft insertion is achieved through the jet generated by the air jet. A yarn feeder is required during its use.

[0003] The existing patent discloses a yarn feeder for an air jet loom (publication number: CN214168270U). During use, the yarn can be fed directly from the double wheels into the air jet loom, and the problem of yarn slack easily occurs. However, during operation, the position of the rotating shaft B is fixed, and the height cannot be freely adjusted. Therefore, when the tension strength of the yarn is too high, the position cannot be adjusted according to the tension, which easily leads to the yarn breaking due to long-term tension. Therefore, the utility model proposes a yarn feeder for an air jet loom. Utility Model Content
