Auxiliary spraying nozzle with triangular section

Abstract

The invention discloses an auxiliary spraying nozzle with a triangular section, which is applied in a jet weaving machine. An inner cavity of the auxiliary spraying nozzle comprises a triangular part and a semicircular part; and the width of the tip end part of the triangular part is 0.45-0.75mm, and the length of the tip end part of the triangular part is 3.0-4.2mm. By use of the auxiliary spraying nozzle with the triangular section, parallel warps are divided, the blocking force to the warps can be reduced, so that the auxiliary spraying nozzle leads the warps to tend to be stable and is beneficial to weaving ultrafine warps.

Description

technical field [0001] The invention belongs to the field of looms and relates to an air-jet loom, in particular to an auxiliary nozzle applied to an air-jet loom. Background technique [0002] see figure 1 , figure 2 As shown, the nozzle size of the auxiliary nozzle is flat, and the thickness of the pipe wall is less than 0.5mm. The nozzle of the auxiliary nozzle is opened on a flat section. The gas moves along the nozzle chamber to the nozzle, and the airflow suddenly turns when it reaches the upper part of the nozzle chamber, and is ejected from the nozzle. The continuation of the weft insertion airflow mainly depends on the auxiliary jet flow. Therefore, the shape of the auxiliary nozzle and the control of the direction, speed and flow of the auxiliary jet flow are the key to the weft insertion quality. [0003] In the way of special-shaped reed, the installation position of the nozzle is greatly restricted by the weaving process. When weaving fabrics with ultra-fin...
