Description

Technical Field

[0001] The utility model relates to the technical field of air jet looms, in particular to an anti-breakage thread feeding mechanism for air jet looms. Background Art

[0002] An air jet loom is a shuttleless loom that uses a jet of air to pull the weft yarn through the shed. It uses air as the weft insertion medium, and the compressed air jet creates frictional traction on the weft yarn, pulling it through the shed and thus completing the weaving process.

[0003] Chinese Patent Publication No. (CN221626503U) discloses an anti-breaking wire feeding mechanism for an air jet loom, comprising a base, a slide groove formed inside the base, and an anti-breaking wire feeding mechanism for the air jet loom on top of the base. The anti-breaking wire feeding mechanism for the air jet loom includes an internally threaded slider slidably mounted inside the slide groove. The anti-breaking wire feeding mechanism of the air jet loom passes the yarn into the interior of the wire loop, and the air jet loom operates to cause the yarn to slide inside the wire loop. The yarn then deviates to the right, squeezing the insertion rod and contacting the pressure sensor. The pressure sensor then transmits a signal to a servo motor, which then drives the wire loop to move rightward to separate the yarn from the inner wall of the wire loop. When the yarn deviates to the left, squeezing the insertion rod at one end of the left side and contacting the pressure sensor, the servo motor drives the wire loop to move leftward to separate the yarn from the inner wall of the wire loop. The yarn moves inside the smooth wire loop, thereby preventing it from being stuck.

[0004] However, the above utility model still has the following problems: in actual use, the above utility model can only achieve the anti-breaking effect for the yarn that is laterally deviated. For vertical deviation, that is, when the yarn deviates upward or downward during the feeding process, it does not have the effect of adjusting the vertical position of the wire loop, resulting in the risk of breaking the yarn once the yarn deviates vertically, so it needs to be improved.
