Problems solved by technology

[0005] The above situation does not meet the control requirements of the auxiliary nozzle, and the residual air flow in the air pipe will affect the starting speed of the next auxiliary jet flow. Therefore, increasing the air flow speed in the air pipe is an important goal of the auxiliary nozzle air supply system

Abstract

The invention discloses an auxiliary jet air supply system with an exhaust valve. The auxiliary jet air supply system with the exhaust valve comprises a plurality of auxiliary jets arranged on an special-shaped reed, the rear ends of the auxiliary jets are arranged on an auxiliary jet seat, the auxiliary jets are connected with the exhaust valve through an air pipe, the exhaust valve is connected with a two-position three-way electromagnetic gas valve, and the two-position three-way electromagnetic gas valve is controlled through an electromagnetic gas valve time control system. The exhaust valve is additionally arranged in an air channel from the electromagnetic gas valve to the auxiliary jets, airflow remaining in the air pipe is exhausted, when high pressure airflow enters the air pipe and inner cavities of the auxiliary jets next time, air resistance can be reduced, the needed time when the airflow passes through the air pipe can be shortened, and auxiliary airflow jet speed is improved. Thus, response speed of auxiliary jet airflow can be improved on the premise that air supply pressure is not increased, airflow control force of the auxiliary jets is enhanced, and high-speed adaptability of an air-jet loom is improved.

Description

technical field [0001] The invention belongs to the field of air-jet looms, and relates to an auxiliary jet flow controller of an air-jet loom, in particular to an auxiliary nozzle air supply system with an exhaust valve. [0002] Background technique [0003] The auxiliary nozzle air supply system is applied to the weft insertion mechanism of the air-jet loom, and is specifically applied to the injection system of the auxiliary nozzle of the air-jet loom. The weft insertion jet air diverges very quickly, and the main jet airflow will attenuate greatly after tens of millimeters. The continuation of the weft insertion airflow mainly depends on the supplement of the auxiliary jet airflow, and the speed of the weft insertion airflow cannot be lower than the weft yarn flying speed (now the weft yarn flies over the reed The speed of the groove reaches 120 m / s, and the component of the speed of the auxiliary jet flow reaching the adjacent area of ​​the weft yarn flight path in th...
