Nozzle buncher for air jet loom

Abstract

The invention discloses a nozzle buncher for an air jet loom. The nozzle buncher for the air jet loom comprises a sleeving part capable of sleeving the outer circumference of a main nozzle and a cluster injection part, and the sleeving part is provided with a cavity capable of accommodating a plurality of spray pipes; and the cluster injection part is arranged at the end, away from the main nozzle, of the sleeving part and provided with an air injection runner capable of communicating with the cavity, and an outlet allowing airflow to pass through is formed in the end, away from the sleeving part, of the air injection runner. By using the nozzle buncher for the air jet loom, the airflow jetted by a plurality of jet pipes of the main nozzle of the air jet loom can be bunched in the air injection runner of the bunching jet part, so that the airflow jetted from the outlet of the nozzle buncher for the air jet loom is concentrated in the center of a reed groove of a reed and is aligned with the center of the reed groove, so that deflection of the airflow is reduced, weft stop frequency is reduced, the working efficiency of the air jet loom is improved, and yield of enterprises is increased.

Description

technical field [0001] The invention relates to the technical field of clustering devices, in particular to a nozzle cluster for an air-jet loom. Background technique [0002] The air-jet loom is a shuttleless loom that uses jet air to pull the weft through the shed. When pulling the weft yarn, the main nozzle of the air-jet loom is aligned with the center of the reed groove of the reed, and the jet air is used to insert the weft. When the reed rotates to a predetermined position, the scissors quickly cut the weft yarn in the main nozzle. [0003] At present, the main nozzles of air-jet looms have multiple forms such as double jets, four jets, six jets or eight jets. Such as figure 1 As shown, it is a four-jet air-jet loom. The main nozzle 300 of the air-jet loom has four nozzles 301. Since the four nozzles 301 are stacked together, it is impossible to ensure that each nozzle 301 can be simultaneously connected with the steel The alignment of the centers of the reed slots...

AI Technical Summary

Problems solved by technology

like figure 1 As shown, it is a four-jet air-jet loom. The main nozzle 300 of the air-jet loom has four nozzles 301. Since the four nozzles 301 are stacked together, it is impossible to ensure that each nozzle 301 can be simultaneously connected with the steel The centers of the reed grooves 401 of the reed 400 are aligned, resulting in deflection of the sprayed airflow, increasing the number of weft stops, and reducing the working efficiency of the air-jet loom
