[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a high-twist yarn weft insertion device for an air-jet loom, comprising an air compressor 1, a pressure pipe 2 connected to the side wall of the air compressor 1, an installation pipe 3 inserted into the top of the pressure pipe 2, and a nozzle 5 connected to the top of the installation pipe 3. Compressed air inside the air compressor 1 is delivered to the inside of the nozzle 5 through the pressure pipe 2 and the installation pipe 3. A disassembly mechanism 4 is provided inside the installation pipe 3. A sieve plate 6 is fixedly connected inside the installation pipe 3. The sieve plate 6 is used to sieve the compressed air. A fan 9 is rotatably connected to the bottom of the sieve plate 6. A cleaning rod 10 is fixedly connected to the top of the fan 9. A cleaning pad is provided on the top of the cleaning rod 10. The cleaning pad is in contact with the bottom of the sieve plate 6. The rotation of the fan 9 drives the cleaning rod 10 to rotate. During the rotation of the cleaning rod 10, the cleaning pad is driven to clean the bottom of the sieve plate 6. A connecting frame 7 is fixedly connected to the side wall of the pressure pipe 2. A protective component 8 is provided inside the connecting frame 7.

[0033] Reference Figures 3-5 The disassembly mechanism 4 includes a disassembly plate 41, which is slidably connected inside the mounting tube 3. Pushing the disassembly plate 41 allows it to slide stably inside the mounting tube 3. The disassembly plate 41 is elastically connected to the mounting tube 3 via a return spring 43. One end of the return spring 43 is fixedly connected to the side wall of the disassembly plate 41, and the other end of the return spring 43 is fixedly connected to the inner side wall of the mounting tube 3. During the sliding process, the disassembly plate 41 compresses the return spring 43, causing it to deform. During reset, the spring 43 rebounds, causing the disassembly plate 41 to rebound and reset. A disassembly block 42 is fixedly connected to the side wall of the disassembly plate 41. The disassembly block 42 is slidably connected inside the mounting tube 3 and inserted into the pressure tube 2. During the sliding process, the disassembly plate 41 causes the disassembly block 42 to engage with the pressure tube 2, improving the stability of the connection between the pressure tube 2 and the mounting tube 3.

[0034] Reference Figures 1-2 The protective component 8 includes a fixed rod 81, which is fixedly connected inside the connecting frame 7. A movable block 83 is slidably connected to the outer surface of the fixed rod 81. A buffer rod 84 is hinged to the top of the movable block 83. The movable block 83 is slidably connected inside the connecting frame 7. When the buffer rod 84 is subjected to vibration and pressure, it moves, causing the movable block 83 to slide stably between the outer surface of the fixed rod 81 and the inside of the connecting frame 7. The movable block 83 is elastically connected to the connecting frame 7 through a positioning spring 82. One side of the movable block 83 is connected to the positioning spring 82. One end of the positioning spring 82 is fixedly connected to the inner wall of the connecting frame 7. During the sliding process of the moving block 83, the positioning spring 82 is squeezed, causing the positioning spring 82 to deform. When resetting, the rebound of the positioning spring 82 drives the moving block 83 to rebound and reset. The end of the buffer rod 84 is hinged with a protective plate 85. The protective plate 85 is made of hard rubber and is arc-shaped. The top of the protective plate 85 is in contact with the outer surface of the nozzle 5. The arc-shaped protective plate 85 is used to protect the bottom of the nozzle 5.

[0035] Working principle: During use, the air compressor 1 compresses the air. When the compressed air is delivered to the nozzle 5 through the pressure pipe 2, the nozzle 5 ejects the compressed air at high speed, forming a high-speed airflow. The friction and traction force generated by the high-speed airflow on the weft yarn enable the weft yarn to gain initial speed and enter the weft insertion channel, completing the weft insertion work of the high-twist yarn of the air-jet loom. When the compressed air enters the installation pipe 3 from the pressure pipe 2, it is screened by the sieve plate 6. At the same time, the movement of the compressed air drives the fan 9 to rotate. The rotating fan 9 drives the cleaning rod 10 to rotate, cleaning the sieve plate 6 and preventing clogging. When the nozzle 5 is impacted by the compressed air, the bottom of the nozzle 5 is protected by the protective plate 85. When the nozzle 5 vibrates, it drives the protective plate 85 to move. The movement of the protective plate 85 drives the buffer rod 84 and the moving block 83 to move. The moving block 83 slides after squeezing the positioning spring 82 on the outer surface of the fixed rod 81, which provides a buffer protection effect for the nozzle 5.

[0036] When the nozzle 5 is damaged after long-term use and needs to be disassembled and replaced, the disassembly plate 41 is pushed and the reset spring 43 is squeezed, which drives the disassembly block 42 into the interior of the mounting tube 3. Then the mounting tube 3 is disassembled from the interior of the pressure tube 2, thus satisfying the disassembly and replacement of the nozzle 5.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
