A main nozzle of an air-jet loom with continuously adjustable intake rotation and intake flow

Abstract

The invention relates to an air-jet loom main nozzle with continuously adjustable air intake curl and air intake flow. The air-jet loom main nozzle comprises a rotatable air intake ring, a nozzle core, a nozzle shell, a nozzle support, a positioning motor, a scheduling motor support and a scheduling motor. The rotatable air intake ring is in butt joint with the nozzle shell and is provided with an air intake channel. The nozzle core is located between the rotatable air intake ring and the nozzle shell. The nozzle shell is supported by the nozzle support. The positioning motor is connected with the nozzle core and drives the nozzle core to move between the rotatable air intake ring and the nozzle shell. The scheduling motor is installed on the scheduling motor support and provided with a driving gear, and the rotatable air intake ring is provided with a transmission gear meshed with the driving gear. Main jet streams of an air-jet loom can be controlled continuously, and therefore the main jet streams with different types of vortex strength are formed, and the untwisting effects of yarns different in twist direction or material are effectively improved in the air stream jet process.

Description

technical field [0001] The invention relates to a composition mechanism of an air-jet loom, in particular to a main nozzle of an air-jet loom with continuously adjustable air intake rotation and air flow, and belongs to the technical field of textile machinery. Background technique [0002] In the textile weaving process, the textile will have broken threads or too many burrs on the surface, which will affect the overall aesthetics and mechanical properties of the fabric, and this is mainly due to the continuous contact and friction of the yarn during the weaving process. When the mechanical properties of the thread are reduced, the yarn is untwisted so that it breaks. A large part of the reason for this is that when the weft thread is inserted, due to the action of the airflow, the weft thread is also untwisted while it is moving forward, which makes the weft thread suffer from tension or friction and appear faults and burrs. [0003] With the increasing application of tex...

AI Technical Summary

Problems solved by technology

Since the two ends of the weft thread are free to relax after the weft insertion action is completed in the weaving process, during the beating-up process accompanied by the closure of the cloth fell, stress is generated on the weft thread to balance the force of the warp thread, and the weft thread part in the middle position is due to the warp thread on both sides. There are many, so it is difficult to shrink, so its internal stress is relatively large. Although the elasticity of the weft yarn is greater than that of the warp yarn, if the weft yarn has a large airflow field rotation during the weft insertion process, when the twist direction and rotation are inconsistent, the weft yarn will be warped. There will be untwisting, which may cause the weft yarn to break when beating up, which makes weaving impossible to complete smoothly
