Injection nozzle for water jet loom

Abstract

The present invention relates to an injection nozzle for a water jet loom, comprising: a first filtering member (20) inside a spray water inflow path (16) for filtering foreign materials included in spray water flowing through a spray nozzle (2), which has a needle (8) inserted into a body (4). A second filtering member (22) is composed at the fore-end part of the needle (8). A stabilizer (24) and a converging member (28) are composed to spray the spray water, which has foreign materials filtered through first and second filtering members (22), through a discharge hole (32) after purifying and focusing the spray water. A fixing bracket (34) having an insertion part (36) for inserting a body (4) is composed to prevent the vibration of the spray nozzle (2) by the spray water sprayed at a high speed through the discharge hole (32), and a combination member (48) is composed to fix the body (4) with a coupling screw (52) by being coupled to a hanging protrusion (46) formed on the body (4). Thus, the manufacture thereof is facilitated by simplifying the exterior structure of the spray nozzle, and the speed of the spray water can be increased by preventing the vibration of the spray nozzle by the spray water. And the high-speed operation of a loom is enabled by increasing the tractive force of the weft in the process of increasing the speed of the spray water being sprayed through the spray nozzle, and the loom can be operated for a long time continuously by preventing foreign materials from being stuck in the stabilizer in the spray nozzle.

Description

technical field [0001] The present invention relates to a nozzle for a water-jet loom, in particular to a nozzle for a water-jet loom that can prevent the nozzle from vibrating due to high-pressure jet water sprayed at high speed, and can also be applied to an existing fixed bracket. Background technique [0002] Ordinary water-jet looms pick and shuttle the weft yarns between the open warp yarns through the jetting of the nozzles. At this time, the jetting water is jetted at an extremely fast and ultra-high speed to insert the weft. [0003] The high-pressure spray water supplied by the nozzle flows into the nozzle and then changes direction and sprays in all directions through high pressure. At this time, the high-pressure spray water will cause the nozzle to vibrate, thereby reducing the concentration of the spray water. [0004] In order to solve the above problems, a separate bracket has been used in the past, and a fixed nozzle is connected to the bracket to prevent th...

Problems solved by technology

[0003] The high-pressure spray water supplied by the nozzle flows into the nozzle and then changes direction and sprays in all directions through high pressure. At this time, the high-pressure spray water will cause the nozzle to vibrate, thereby reducing the concentration of the spray water

[0004] In order to solve the above problems, a separate bracket has been used in the past, and a fixed nozzle is connected to the bracket to prevent the vibration of the nozzle. However, the forming steps for manufacturing a nozzle that matches the shape of the connection structure of the bracket are complicated, and the manufacturing time of the nozzle is complicated. Long, especially when the shape of the nozzle is deformed, the nozzle cannot be connected to the bracket, so the nozzle and the bracket need to be replaced at the same time, which increases the cost burden
