Description

Technical Field

[0001] The present invention belongs to the technical field of textile equipment, and particularly relates to a nozzle for a water jet loom. Background Art

[0002] A water jet loom is a commonly used high-efficiency weaving equipment in modern textile industry. Its working principle is to use high-pressure water flow to inject the weft yarn into the weaving shed to form a fabric. This loom is particularly suitable for weaving natural fiber fabrics with strong hygroscopicity such as cotton and linen, because such fibers can better combine with the warp yarns through the action of water. The most important component of a water jet loom is the nozzle. The nozzle sends water or other liquids into it through a pump. The liquid is compressed and accelerated inside the nozzle and then sprayed out through the nozzle to form a high-speed jet flow. This jet flow has the characteristics of high speed, high pressure, and high impact force, and can effectively interweave the yarns on the fabric to form a fabric.

[0003] The water jet loom has high working efficiency. After the weft yarn is used up during work, it needs to be replaced in time. When replacing the weft yarn on a conventional water jet loom, after the new weft yarn is installed, the operator needs to thread the yarn end through the nozzle before the loom can be started normally. This not only requires the worker to master the threading technique proficiently, but also takes a long time for the entire replacement process. In actual production, an operator often needs to take care of dozens or even hundreds of water jet looms at the same time. The operator needs to replace the weft yarns of multiple water jet looms in time, and the long time for weft yarn replacement seriously delays the working efficiency of the operator. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a nozzle for a water jet loom. The present invention can expand the nozzle when replacing the weft yarn, and the operator only needs to pull the yarn end through the nozzle, so that the yarn end can be conveniently threaded through the nozzle, effectively reducing the time for weft yarn replacement, reducing the working pressure of the operator, and improving the working efficiency of the operator.

[0005] The technical solution adopted to solve the above technical problem is: a nozzle for a water jet loom, including a base and a nozzle assembly. The base is fixed on the side of the water jet loom, the nozzle assembly is arranged on the base, the nozzle assembly is composed of a left nozzle part and a right nozzle part, the bottom of the left nozzle part and the bottom of the right nozzle part are hinged, an adjusting mechanism is slidably connected to the front side of the base, a driving mechanism is slidably connected to the side of the base, and a supporting mechanism is slidably connected to the rear side of the base;

[0006] The driving mechanism can drive the adjusting mechanism to slide horizontally left and right;

[0007] The horizontal left and right sliding of the adjusting mechanism can drive the nozzle assembly to expand or close;

[0008] The supporting mechanism can support the nozzle assembly.

[0009] Through the above technical solution, during normal operation, the weft thread passes through the nozzle assembly, the water pump supplies water into the nozzle assembly, and the high-pressure water flow injects the weft thread into the water-jet loom. The water-jet loom completes the textile production. When the weft thread needs to be replaced, after the weft thread is installed in place, pull out the thread end, push the thread end and the drive mechanism together to the rear end of the nozzle assembly. The drive mechanism drives the adjustment mechanism, and the adjustment mechanism unfolds the nozzle assembly. Put the thread end into the unfolded nozzle assembly, pull the drive mechanism back to the front end of the nozzle assembly. After the drive mechanism is reset, the adjustment mechanism closes the nozzle assembly, that is, the replacement of the weft thread is completed. The replacement of the weft thread is simple and fast, effectively reducing the working pressure of the operators and improving the working efficiency of the operators.

[0076] When the weft needs to be replaced, after the weft is installed in place, the thread end is pulled out, the adjusting rod 43 is pulled out from the adjusting tube 41, and the thread end is placed in the thread receiving groove 431, which drives the thread end and the top rod to slide horizontally toward the rear end of the base 1, that is, drives the adjusting tube 41 to slide horizontally toward the rear end of the base 1, and the driving rod 42 slides horizontally toward the rear end of the base 1 accordingly. The horizontal sliding of the driving rod 42 toward the rear end of the base 1 can drive the second transmission gear 332 to rotate forward, and the forward rotation of the second transmission gear 332 can drive the transmission rod 33 to rotate forward, and the forward rotation of the transmission rod 33 can drive the first transmission gear 331 to rotate forward.

[0077] When the first transmission gear 331 rotates forward, the first base plate 31 and the second base plate 32 slide horizontally in the direction away from each other, and the first connecting rod 34 and the second connecting rod 35 can respectively drive the left nozzle component 21 and the right nozzle component 22 to rotate in the direction away from each other, that is, drive the nozzle assembly 2 to unfold.

[0078] Then put the thread end into the unfolded nozzle assembly 2, pull the top rod to slide horizontally toward the front end of the base 1, and reset the adjustment tube 41. At this time, the driving rod 42 will slide horizontally toward the front end of the base 1. The horizontal sliding of the driving rod 42 toward the front end of the base 1 can drive the second transmission gear 332 to reverse, and the reversal of the second transmission gear 332 can drive the transmission rod 33 to reverse, and the reversal of the transmission rod 33 can drive the first transmission gear 331 to reverse;

[0079] When the first transmission gear 331 rotates reversely, the first base plate 31 and the second base plate 32 slide horizontally toward each other, and the first connecting rod 34 and the second connecting rod 35 can respectively drive the left nozzle component 21 and the right nozzle component 22 to rotate toward each other, that is, drive the nozzle assembly 2 to close;

[0080] At this point the weft thread replacement is complete and the machine can be started immediately.

[0081] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
