Abstract

The invention provides an air-jet weft insertion mechanism capable of improving accuracy, which includes a yarn bobbin, a weft yarn, a yarn guide, a fixed main nozzle, a swinging main nozzle, a profiled reed and an auxiliary nozzle. The weft yarn of the yarn bobbin is guided out and fixed through the yarn guide The main nozzle, the weft yarn ejected from the fixed main nozzle is introduced into the oscillating main nozzle, the weft yarn exported by the oscillating main nozzle passes through the reed hole of the special-shaped reed, and auxiliary nozzles arranged in parallel are arranged along the direction of the reed hole of the special-shaped reed, and the reed holes of the special-shaped reed are connected to the shuttle mouth. The beneficial effect is that by setting the swing main nozzle, the angle difference between the fixed main nozzle and the reed hole of the profiled reed is adjusted, and the accuracy of jetting weft yarn is improved.

Description

technical field [0001] The invention belongs to the field of weft insertion mechanisms for textile machines, and in particular relates to an air-jet weft insertion mechanism capable of improving accuracy. Background technique [0002] The air-jet weft insertion device of the loom draws the weft yarn with the jetted compressed airflow, and takes the weft yarn through the shed for weaving. The most important feature of the air-jet weft insertion device of the loom is its fast production speed and high labor productivity. It is suitable for the production of plain and textured fabrics, fine extra-high-density fabrics and large-batch fabrics. The weft insertion of the air-jet loom uses compressed air as the weft insertion carrier, and uses the high-speed airflow generated when the compressed air is released through the small hole to pull the weft yarn through the shed to complete its weft insertion function. However, the existing air-jet weft insertion mechanism is only provide...
