Abstract

The invention discloses a system for measuring the stability of a weft yarn carried by a main jet flow. The system comprises a main nozzle and an air supply system connected with the main nozzle, wherein the weft yarn is wound on a weft yarn bobbin and lead into the main nozzle; the main nozzle is arranged on a main nozzle seat; the main nozzle seat is arranged on a working platform; the working platform is also provided with an angle square; and the scale end of the angle square is located on the extension line of a main nozzle guide pipe. The system for measuring the stability of the weft yarn carried by a main jet flow disclosed by the invention adopts a simple and feasible measuring means and can effectively measure the stability condition of the weft yarn.

Description

technical field [0001] The invention belongs to the field of air-jet looms, and in particular relates to a weft insertion system of an air-jet loom. More specifically, the invention relates to a system for measuring the stability of weft yarns carried by a main jet flow. Background technique [0002] The air-jet loom uses airflow to achieve weft insertion. The air-jet loom inserts 800-1000 wefts per minute. Each weft insertion corresponds to the weft yarn flying through the shed once, and the weft yarn flying speed reaches 100 m / s. Only when the weft yarn flying speed is high, can the loom reach the high speed of 800-1000 rpm. A high-speed air-jet loom must have a high-quality main nozzle. After passing through the main nozzle, the weft yarn must reach a high speed of more than 100 m / s, and the high speed must be high and stable. [0003] The actual operating speed of the newly added air-jet loom in the factory reaches 750-900 rpm. In 1988, the speed of the air-jet loom wa...
