Embodiment

[0044] Such as Figure 1~Figure 10 Shown is the multi-jet combination device of the weft insertion mechanism of the water jet loom, including several needle seats 2 installed on the bracket 1, each needle seat 2 is provided with a mounting hole 21, and each mounting hole 21 is equipped with There is a needle body 22, and each needle body is equipped with a needle 26, and there is a first position point 61 on the bisector of the minimum permissible opening 6 formed by the upper and lower warp threads when the water jet loom starts weft insertion from the weaving fell 3, The distance between the first position point 61 and the fabric fell is the minimum allowable distance 62; the center position of the minimum design allowable space 5 of each spray needle is set at two parallel openings parallel to the minimum allowable opening 6 drawn from the first position point 61. The triangular area 4 is formed by the line 64 and the maximum allowable position 66 away from the fabric fell ...

Abstract

The invention discloses a multi-jet-needle combination device for weft insertion mechanisms of water-jet looms. The multi-jet-needle combination device comprises a plurality of needle holders (2) mounted on a support (1). Each needle holder (2) is provided with a mounting hole (21). A jet needle member (22) is mounted in each mounting hole (21). A jet needle (26) is mounted in each jet needle member. The multi-jet-needle combination device is characterized in that when a fell (3) jets water and a loom inserts wefts, a bisection of a smallest allowed opening (6) formed between an upper and lower warp layers is provided with a first position (61); the distance from the first position (61) to the fell is a smallest allowed distance (62); the center of smallest designed allowed space (5) of each jet needle is provided two parallel lines (64) parallel with the smallest allowed opening (6) and inserted from the first position (61), the parallel lines and a largest allowed position (66) of a reed from the fell (3) during beating up form a triangular region (4). The air-jet looms with the multi-jet-needle combination device can be used to produce diversified textiles which are far more than existing textiles, and beating-up movement is unaffected.

Description

technical field [0001] The invention belongs to the technical field of design of a weft insertion mechanism of a water jet loom, and in particular relates to a multi-jet combination device of the weft insertion mechanism of a water jet loom. Background technique [0002] Water-jet loom is a kind of shuttleless loom, it inserts weft through water jet, compared with air-jet loom, it has the characteristics of good jet clustering, low production energy consumption, and low price. The function of the weft insertion mechanism of the water jet loom is to introduce the weft yarn into the shed so that it can be interwoven with the warp yarn to form a fabric. The weft insertion mechanism of the water-jet loom uses water as the carrier, and the weft yarn is introduced into the shed by the jet of high-pressure water relying on the friction between the water flow and the yarn, which makes the water-jet loom have advantages in terms of cost, labor saving, and energy saving. [0003] In ...
