Description

Technical Field

[0001] This utility model relates to the field of nozzle fixing technology, and more specifically to a nozzle fixing clamping device. Background Technology

[0002] An air-jet loom is a textile machine that uses airflow to guide the weft yarn through the warp yarn. Its working principle is ingenious and efficient. During the weaving process, the air-jet loom sprays compressed air at high speed through nozzles to form an airflow, which quickly and accurately feeds the weft yarn into the shed formed by the interlacing of the warp yarns.

[0003] A search revealed a Chinese patent with authorization announcement number CN205133896U, which discloses an air-jet loom. This device features high nozzle outlet wind speed, good airflow consistency among nozzles, good airflow concentration, and long range, resulting in smooth airflow, successful weft insertion, increased loom speed, weaving efficiency, and reduced energy consumption. However, when installing the main nozzle, only the end of the nozzle is attached to the device. During operation, the device generates a strong airflow, which can cause the main nozzle to loosen over long-term use, affecting the normal operation of the device. Utility Model Content

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1-4 This utility model provides a nozzle fixing and clamping device, including a base plate 1. A first clamping block 2 is fixedly connected to the upper surface of the base plate 1 by bolts. A second slot 8 for placing the main nozzle body is opened at the middle position of the upper surface of the first clamping block 2. Symmetrical square slots 9 are opened on the upper surface of the first clamping block 2 on both sides of the second slot 8. A square rod 10 is slidably connected in each of the two square slots 9. The tops of the two square rods 10 are fixedly connected to the second clamping block 3 by bolts. A first slot with the same shape as the second slot 8 is opened on the lower surface of the second clamping block 3. 7. Two round holes 11 are provided on the square rod 10. Two through holes 12 are provided on the inner walls of both sides of the square groove 9. A first screw 13 for fixing the square rod 10 is provided in the through hole 12. The first screw 13 passes through the round hole 11. The protruding part on the main nozzle body can be clamped by the second slot 8 provided on the first clamping block 2 and the first slot 7 provided on the second clamping block 3. The square rod 10 can be fixed by the round hole 11 and the through hole 12 and the first screw 13, thereby fixing the main nozzle body.

[0024] In this invention, a U-shaped frame 4 is bolted to one side of the base plate 1. Two symmetrical vertical plates 5 are provided on the upper surface of the U-shaped frame 4. A first arc-shaped clamping plate 14 is detachably connected to the top of the two vertical plates 5 via bolts. A second arc-shaped clamping plate 15 is provided on the upper surface of the first arc-shaped clamping plate 14. Both the second arc-shaped clamping plate 14 and the first arc-shaped clamping plate 15 have two symmetrical clearance holes, and a second screw 16 is installed in the two clearance holes on the same side. Through the provided first arc-shaped clamping plate 14 and second arc-shaped clamping plate 15, the front half of the main nozzle body can be further... The device secures the main nozzle body to both the rear and front halves simultaneously, significantly increasing the stability of the main nozzle body. Grooves 17 are provided on the inner walls of both the first and second grooves 7 and 8, respectively. The length of each groove 17 is the same as the length of the protruding portion of the rear half of the main nozzle body. These grooves 17 clamp the protruding portion of the rear half of the main nozzle body while restricting its position, preventing horizontal displacement and further enhancing stability. Multiple clearance features are provided within the grooves 17. The positioning grooves 18 and shims 18 are formed along the arc-shaped inner wall of the groove 17. Each of the multiple shims 18 contains a rubber pad 19 with the same shape as the positioning groove 18. The positioning grooves 18 and rubber pads 19 protect the surface of the main nozzle body while clamping it, preventing scratches and affecting its appearance. One side of the rubber pad 19 slightly protrudes from the positioning groove 18, and gaps exist between both sides of the rubber pad 19 and the inner walls of both sides of the positioning groove 18. This allows for compression of the rubber pad 19 when the main nozzle body is clamped. The force of squeezing the rubber pad 19 reacts to the main nozzle body, clamping and fixing it better. When the square rod 10 is fully inserted into the square groove 9, there is a gap between the first clamping block 2 and the second clamping block 3. The first clamping block 2 is provided with a clearance opening 6. The clearance opening 6 can be used to avoid the first screw 13 when it is installed, making installation convenient. The first clamping block 2 on the base plate 1 has two sets of symmetrical mounting holes on both sides. Each set has two holes, and the two mounting holes in the same set are also symmetrically opened. The device can be easily installed on the air-jet loom through the mounting holes.

[0025] The use of this utility model involves the following steps:

[0026] S1: When installing the main nozzle body, first install the base plate 1 on the air-jet loom, then insert the protruding part of the rear half of the main nozzle body into the second slot 8 on the first clamping block 2, and then install the second clamping block 3. During installation, insert the two square rods 10 on the second clamping block 3 into the corresponding square slots 9 respectively, and then press the second clamping block 3 until the through hole 12 and the round hole 11 coincide. Then, insert the first screw 13 through the round hole 11 and the through hole 12, and then install the nut to fix it.

[0027] S2: The first half of the main nozzle body is installed on the second arc-shaped clamping plate 15. Then the first arc-shaped clamping plate 14 is installed, and the first arc-shaped clamping plate 14 and the second arc-shaped clamping plate 15 are fixed by the second screw 16, thus completing the clamping and fixing of the main nozzle body.
