Problems solved by technology

Since the existing sub-nozzle can only jet airflow in one direction, that is, the airflow injected by the sub-nozzle can only pull the weft yarn to fly in one direction. If the weft yarn needs to fly in the opposite direction, the structure of the existing sub-nozzle can do nothing

Embodiment Construction

[0009] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0010] As shown in the figure: the auxiliary nozzle for the bidirectional weft insertion air-jet loom in the embodiment is mainly composed of an auxiliary nozzle seat 1, a left auxiliary nozzle 2 and a right auxiliary nozzle 3, and the auxiliary nozzle seat 1 is provided with two Parallel side by side nozzle installation holes, the left sub-nozzle 2 and the right sub-nozzle 3 are respectively installed in the nozzle installation holes, the left sub-nozzle 2 is provided with a left air outlet 4, and the right sub-nozzle 3 is provided with There is a right air outlet 5.

[0011] like figure 1 As shown, in the present invention, there should be a certain distance between the left sub-nozzle 2 and the right sub-nozzle 3, and the preferred distance range is 5 mm to 30 mm. In the illustrated embodiment, there is only one left air outlet 4 on the left auxiliary nozz...

Abstract

The invention relates to an auxiliary jet used for a two-way weft insertion air jet loom. The auxiliary jet used for the two-way weft insertion air jet loom comprises an auxiliary jet pipe base and is characterized in that two jet pipe mounting holes formed in parallel are formed in the auxiliary jet pipe base, a left auxiliary jet pipe and a right auxiliary jet pipe are installed in the jet pipe mounting holes respectively, at least one left air outlet is formed in the left auxiliary jet pipe, and at least one right air outlet is formed in the right auxiliary jet pipe. The auxiliary jet used for the two-way weft insertion air jet loom is simple in structure, reasonable in design and capable of achieving two-way weft insertion of the air jet loom and improving the quality of fabric.

Description

technical field [0001] The invention relates to an accessory part of an air-jet loom, in particular to a sub-nozzle for a two-way weft insertion air-jet loom, and belongs to the technical field of textile machinery. Background technique [0002] The weft insertion action of the current air-jet loom is to bring the weft yarn from one side of the loom to the other side by the airflow, that is, the weft yarn is a one-way movement. Since the weft insertion of the air-jet loom belongs to the free end weft insertion, the tension and twist of the weft yarn will gradually weaken during the flight process, resulting in uneven tension of the fabric in the width direction, and color difference between the left and right sides after dyeing. This is a worldwide problem that restricts the development of air-jet looms. One of the available technical means to solve this problem is to use two-way weft insertion. However, one of the key components restricting the two-way weft insertion of th...
