Description

Technical Field

[0001] The utility model relates to the technical field of water spray adjustment for textile machines, in particular to an adjustable water spray port for a water spray textile machine. Background Art

[0002] The water jet of a textile machine is a vital component of a water jet textile machine. This water jet is usually composed of one or more precisely designed nozzles that can spray fine water streams at high speed. These water streams play a vital role in the operation of the water jet textile machine. Specifically, the water stream sprayed by the water jet is mainly used to introduce the weft yarn into the shed of the loom and interweave it with the warp yarn to form a fabric. During the operation of the water jet textile machine, the weft yarn is pulled and passed through the water jet, and the water jet generates negative pressure by spraying water, which tightly adsorbs the weft yarn on the surface of the water stream so that it can be accurately brought into the shed. In this way, the weft yarn and the warp yarn can be interwoven according to the predetermined pattern and density to form the desired fabric.

[0003] At present, the water nozzles of textile machines usually use fixed nozzles. When the diameter of the nozzle needs to be adjusted, the water nozzle is generally replaced. At the same time, in order to ensure the sealing of the water nozzle of the textile machine, it is necessary to firmly install it on the nozzle barrel, which makes it troublesome to adjust the diameter of the nozzle each time, resulting in poor flexibility in adjusting the diameter of the nozzle. Therefore, an adjustable water nozzle for a water-jet textile machine is proposed. Utility Model Content
