Abstract

The invention relates to a special weft yarn air-flow active force testing device for the main jet nozzle of jet loom, which consists of a simulated main jet nozzle of jet loom, a tension sensor (15), a data acquisition card (16), a computer (17) and measured yarn (14); the center line of the simulated main jet nozzle of jet loom and the tension sensor (15) positioned in the same horizontal plane; one end of the measured yarn (14) is fixed on the center of the tension sensor (15), the other end is free; when the free end straightened levelly, it aligns to the weft insertion flow channel of the main jet nozzle of jet loom; and the tension sensor (15) delivers data to the computer (17) through the data acquisition card (16). The invention can obtain the accurate data of weft yarn air-flow active force by testing, is helpful for improving the research of jet loom, and plays a major part in improving the performance of jet loom.

Description

technical field [0001] The invention belongs to the field of data measurement of the main nozzle of an air-jet loom, in particular to a device for testing the force of weft air flow. Background technique [0002] The air-jet loom is the fastest-growing shuttleless loom. Because of the air-flow weft insertion method, the production efficiency of the loom is greatly improved. During the development of air-jet looms, people continue to tap the potential of air-jet weft insertion and study the principle of air-jet weft insertion to improve the working efficiency of air-jet looms. A lot of work has been done on the synthesis of the weft insertion flow field, and the characteristics of the weft insertion flow field have been studied by calculating the fluid. However, a large number of studies only stay on theoretical calculations, and ignore many actual situations. They adopt ideal premises, and most of the calculation parameters use empirical values, lacking experimental verific...
