Hydraulic loom splash-proof type nozzle

Abstract

The invention provides a hydraulic loom splash-proof nozzle. The hydraulic loom splash-proof nozzle comprises a spray-head, multiple water guide wheels and a driving mechanism, wherein the spray-head is internally provided with a main water channel and auxiliary water channels, the auxiliary water channels are arranged at the periphery of the main water channel, the main water channel and the auxiliary water channels are independent with each other, and a water outlet of the main water channel and water outlets of the auxiliary water channels are located at the same plane; the multiple water guide wheels are arranged on the spray-head in a surrounding mode, and the wheel side face of each of the water guide wheels stretches into each of the auxiliary water channels; the driving mechanism is in transmission connection with the multiple water guide wheels so as to drive the multiple water guide wheels to synchronously rotate. The hydraulic loom splash-proof nozzle has the advantages that acceleration is conducted on the water flow in the auxiliary water channels through the multiple water guide wheels, so that the speed of the water flow sprayed out of the main water channel and the speed of the auxiliary water channels are the same, thus the speed difference is eliminated, the formation of spray mist is reduced, the clustering of sprayed water flow is improved, the wefting insertion effect is improved, the service life of parts is prolonged, and the hydraulic loom splash-proof nozzle is beneficial to environmental protection.

Description

Technical field [0001] The invention relates to the technical field of textile machinery, in particular to a splash-proof nozzle of a water jet loom. Background technique [0002] The loom is a machine used to interweave two or more groups of yarns at right angles to form a fabric. Its main structure generally includes a shedding mechanism, a weft insertion mechanism, a beating-up mechanism, a winding mechanism and a warp let-off mechanism. The five mechanisms can cooperate with each other. Interweave the fabric. [0003] The weft insertion nozzle is an important part of the weft insertion mechanism. The water jet loom adopts water jetting to introduce the weft yarn. Because the water flow has a better concentration, the water jet from the nozzle nozzle can carry the weft yarn for a long distance. And because the frictional traction force of water on the weft yarn is relatively large, the water jet loom has obvious advantages in the flight speed and weaving speed of the weft yarn ...

AI Technical Summary

Problems solved by technology

[0004] The spouts on the nozzles in the prior art often produce water mist when spraying water. This is because the viscous force at the inner wall of the spout will cause a difference in the velocity of the water jet at the sprayed water column and the water flow at the spray wall, and the mist produced by the spout will reduce the flow of water. Agglomeration, thus affecting the weft insertion operation, reducing the weft insertion effect, long-term use may easily cause damage to parts, and the generation of water mist will cause water waste, which is not conducive to environmental protection
