Abstract

The invention discloses a needle combined device for a weft insertion mechanism of a water-jet loom, comprising at least four needle seats (2) arranged on a support (1), wherein each needle seat (2) is provided with a mounting hole (3) which is internally provided with a needle body (4); each needle body is internally provided with needles; beginning with a fell (5), the center of the minimal designed allowable space of the first needle (41) is on a bisector (52) of a minimal allowable opening (51) formed by two layers of warps when the water-jet loom carries out weft insertion, and the distance between the center of the minimal designed allowable space of the first needle (41) and a cloth fell is the minimal allowable distance (53). The needle combined device is characterized in that the centers of the minimal designed allowable spaces of the other needles are on a sector (7) formed by two parallel lines, which are extracted out of the center of the minimal designed allowable space of the first needle (41) and are parallel to the minimal allowable opening (51), and the maximum allowable distance between the center of the minimal designed allowable space of the needle and the cloth fell; the minimal designed allowable spaces of all the needles are closed to each other successively; and the centers of the minimal designed allowable spaces of all the needles are not in the same line. The water-jet loom of the invention can produce various texture patterns which further exceed the existing texture patterns, and does not influence beating-up stroke.

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 spray needle 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 uses water jet for weft insertion. Compared with air-jet loom, it has the characteristics of high weft insertion speed, good jet clustering, low production energy consumption, and relatively low noise. 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, la...
