[0015] 1. The staff will first put the water injection pipe on the positioning pipe, then put the tie ring between the two limit rings and tighten it to increase the sealing between the positioning pipe and the water injection pipe. Then the staff will adjust the distance of the water flow sprayed by the high-pressure nozzle according to the size of the woven fabric. When adjusting, the staff will drive the rotating rod and the adjusting plate to rotate by turning the adjustment knob. At the same time, the positioning rod will rotate inside the positioning groove. The adjustment plate is located in front of the water injection channel. Therefore, when the adjustment plate rotates, the area of ​​the water injection channel blocked by the adjustment plate will change, so that the distance of the water flow sprayed by the high-pressure nozzle can be adjusted, and then the distance of the weft insertion can be controlled to adapt to the range of the fabric size that can be woven, avoiding the waste of weft caused by the water flow being sprayed too far;

[0016] 2. The staff can drive the transverse screw to rotate by turning the turntable. The transverse screw drives the connecting plate to slide inside the sliding port by means of the threaded connection with the threaded hole, thereby driving the sliding plate and the high-pressure nozzle to move horizontally. At the same time, the staff can also drive the longitudinal screw to rotate by turning the turntable, and drive the positioning plate to slide longitudinally inside the sliding groove by means of the threaded connection between the longitudinal screw and the positioning plate, thereby adjusting the position of the high-pressure nozzle longitudinally. In addition, the staff can also apply a pushing force to the rotating plate to make the rotating plate rotate between the two fixed plates, thereby driving the limit strip to slide into the limit groove at different positions, thereby adjusting the spray angle of the water flow from the high-pressure nozzle. Each high-pressure nozzle can be adjusted independently, which is convenient for various weaving environments.

[0017] 3. The staff will pull the weft thread around the guide groove and then pass through the fixed ring and let it hang naturally. The guide groove is located directly above the high-pressure nozzle. Therefore, when the weft thread is pulled out from the guide groove, the weft thread hanging between the guide groove and the fixed ring is at the position where the high-pressure nozzle sprays water, which increases the stability of the weft thread position, avoids the occurrence of missing weft thread caused by changes in the weft thread position, and increases the accuracy of weft insertion.

There are two sealing rings 14 in the internal interference fit of the rotating hole 9, and the outer wall surface of the sealing ring 14 is tightly fitted with the inner wall surface of the rotating hole 9. An adjustment knob 15 is fixed to the top of the rotating rod 10, an indicator block 16 is fixed to the top surface of the rotating plate 5, and a positioning tube 17 is fixed to one side of the rotating plate 5. A water injection tube 18 is slidably inserted on the positioning tube 17, and two limit rings 19 are fixed to the surface of the water injection tube 18.

[0028] During use, the staff will first sleeve the water injection pipe 18 on the positioning pipe 17, and then sleeve the clamp ring between the two limit rings 19 and tighten it to increase the sealing between the positioning pipe 17 and the water injection pipe 18. Then the staff will adjust the distance of the water flow sprayed by the high-pressure nozzle 7 according to the size of the woven fabric. When adjusting, the staff will drive the rotating rod 10 and the adjustment plate 11 to rotate by turning the adjustment knob 15. At the same time, the positioning rod 12 will rotate inside the positioning groove 13. The adjustment plate 11 is directly in front of the channel for injecting water into the high-pressure nozzle 7. Therefore, when the adjustment plate 11 rotates, the area of ​​the water injection channel blocked by the adjustment plate 11 will change, so that the distance of the water flow sprayed by the high-pressure nozzle 7 can be adjusted, and then the distance of the weft insertion can be controlled to adapt to the range of woven fabric sizes, avoiding the waste of weft caused by spraying water too far.

[0029] like Figure 2 , Figure 4 and Figure 5As shown, a sliding opening 20 is provided on the top surface of the installation folding plate 1, and a transverse screw 22 is rotatably provided inside the sliding opening 20.

Turntables 23 are fixed to the two ends of the transverse screw 22, and a connecting plate 24 is fixed to the bottom surface of the sliding plate 2. A threaded hole 21 is provided on one side of the connecting plate 24, and the threaded hole 21 is threadedly connected with the transverse screw 22. A sliding groove 26 is provided on the top surface of the sliding plate 2, and a longitudinal screw 27 is rotatably provided inside the sliding groove 26.

The limiting strips 34 and the limiting grooves 33 are slidably arranged, and fixing openings 35 are provided on both sides of the installation folding plate 1, and fixing bolts 36 are rotatably inserted inside the fixing openings 35.

[0030] During use, the staff can drive the transverse screw 22 to rotate by rotating the turntable 23. The transverse screw 22 drives the connecting plate 24 to slide inside the sliding opening 20 by utilizing the threaded connection with the threaded hole 21, thereby driving the sliding plate 2 and the high-pressure nozzle 7 to move horizontally. At the same time, the staff can also drive the longitudinal screw 27 to rotate by rotating the turntable 29, and utilize the threaded connection between the longitudinal screw 27 and the positioning plate 30 to drive the positioning plate 30 to slide longitudinally inside the sliding groove 26, thereby adjusting the position of the high-pressure nozzle 7 longitudinally. In addition, the staff can also apply a pushing force to the rotating plate 5 to make the rotating plate 5 rotate between the two fixed plates 4, thereby driving the limit bar 34 to slide into the limit groove 33 at different positions, thereby adjusting the spray angle of the water flow of the high-pressure nozzle 7. Each high-pressure nozzle can be adjusted independently, which is convenient for various weaving environments.

[0031] like Figure 4 As shown, two mounting plates 37 are fixed on one side of the rotating plate 5, a rotating wheel 38 is rotatably arranged between the two mounting plates 37, a wire guide groove 39 is provided on the surface of the rotating wheel 38, two fixed folding plates 40 are fixed on one side of the rotating plate 5, and a fixing ring 41 is fixed between the two fixed folding plates 40.

[0032] During use, the staff will pull the weft thread to bypass the guide groove 39 and then pass through the fixing ring 41 and let it hang naturally.

Therefore, when the weft thread is pulled out from the guide groove 39, the weft thread hanging between the guide groove 39 and the fixing ring 41 is at the position where the high-pressure nozzle 7 sprays water, which increases the stability of the weft thread position, avoids the occurrence of missing weft threads caused by changes in the weft thread position, and increases the accuracy of weft insertion.
