Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to an air jet nozzle structure of an air jet loom. Background Art

[0002] Looms are also called spinning machines, weaving machines or cotton spinning machines. Early looms were all manpower-driven looms. Shuttleless loom technology has been studied since the 19th century and has been gradually introduced to the international market since the 1950s. Since the 1970s, many new shuttleless looms have been put on the market. Shuttleless looms have achieved remarkable results in improving fabrics and improving the efficiency of looms. They have been widely used in countries around the world and have accelerated the process of weaving equipment transformation. The share of shuttleless looms in many developed countries has reached about 80%, and there has been a general trend of replacing shuttle looms with shuttleless looms.

[0003] The Chinese patent document with publication number CN205934528U discloses an air jet nozzle, which has a cavity between the nozzle and the connector, so that the gas entering from the connector can fill the entire cavity, so that the gas pressure can push the sleeve forward and backward to closely adhere to the end surface of the first bearing, ensuring the advantage that the sleeve can swing;

[0004] However, the nozzle is close to the textile structure during installation, which makes the nozzle and the connecting pipe susceptible to certain vibrations. Long-term vibrations will cause the air pipe of the auxiliary nozzle to loosen and fall off, so it is necessary to improve the connection method in the original equipment. Utility Model Content

The reinforcement device 6 includes a right clamping sleeve 61, a left clamping sleeve 62, a fixing stud 63, a rotating handle 64, a threaded column 65, a reinforcement plate 66, and a limiting module 67. A fixing stud 63 is installed at the front end of the right clamping sleeve 61. The right clamping sleeve 61 is movably connected to the right end of the left clamping sleeve 62. The fixing stud 63 is threadedly fixed to the front end of the left clamping sleeve 62. The rotating handle 64 is arranged at the right end of the threaded column 65. The threaded column 65 is in internal thread fit with the right clamping sleeve 61. A reinforcement plate 66 is arranged at the left end of the threaded column 65. The reinforcement plate 66 is connected to the top of the connecting pipe 5 and the bottom of the fixing sleeve 7. The limiting module 67 is arranged on the top of the reinforcement plate 66. The right clamping sleeve 61 and the reinforcement plate 66 are arranged in parallel at the left and right ends of the threaded column 65. The rotating handle 64, the threaded column 65, and the reinforcement plate 66 are arranged at the same horizontal level in the right clamping sleeve 61.

[0029] Please refer to Figure 5 , a nozzle structure of an air-jet loom. The limiting module 67 includes a mounting frame 671, a limiting spring 672, a fixing plate 673, and a limiting block 674.

[0030] In summary, when in use, fix the fixed bracket 1 on a fixed object, assemble the connecting pipe 5 to the bottom of the fixing sleeve 7, and connect the top end of the fixed pipe 8 above the sandblasting equipment;

[0031] At the same time, nest the right clamping sleeve 61 and the left clamping sleeve 62 at the connection of the fixing sleeve 7 and the connecting pipe 5, and fix them with the fixing stud 63. Manually rotate the rotating handles 64 on both sides, and the rotating handles 64 drive the threaded columns 65 to rotate. The threaded columns 65 are in threaded fit with the threads arranged inside the right clamping sleeve 61 and the left clamping sleeve 62 through straight threads, and then push the two sets of reinforcement plates 66 to contract synchronously, so that the reinforcement plates 66 can play a role of clamping and fixing the fixing sleeve 7 and the connecting pipe 5, thereby preventing the fixing sleeve 7 and the connecting pipe 5 from being easily detached due to accidents during the production work;

[0032] In addition, by arranging the limiting block 674 below the fixing sleeve 7, the limiting block 674 can buffer the vibration force on the fixing sleeve 7 with the cooperation of the limiting spring 672, thereby limiting the fixing sleeve 7 within the movable area, and contacting and rubbing with the connecting pipe 5 on the outside of the limiting block 674, thereby reducing the movement of the connecting pipe 5 due to vibration, effectively reducing the possibility of the connecting pipe 5 falling off, and then limiting the connecting pipe 5 and the fixing sleeve 7 through the limiting module 67, limiting the connecting pipe 5 and the fixing sleeve 7 within the movable area, and reducing the movement of the connecting pipe 5 and the fixing sleeve 7 due to vibration, thereby achieving the purpose of reinforcing the connecting pipe 5 and the fixing sleeve 7 through the reinforcing device 6, preventing the connecting pipe 5 and the fixing sleeve 7 from easily falling off due to vibration, thereby solving the problem that the nozzle and the connecting pipe in the original equipment are easily affected by certain vibrations, and long-term vibration will cause the air delivery pipe of the auxiliary nozzle to loosen and fall off;

[0033] Furthermore, the sandblasting equipment is started to guide the yarn into the fixed tube 8. Under the guidance of the fixed tube 8, the yarn is introduced into the interior of the connecting tube 5. The connecting tube 5 introduces the yarn into the gap of the transmission wheel 9, and the transmission motor 4 is started to drive the transmission wheel 9 to rotate at a high speed, so that the transmission wheel 9 and the yarn are frictionally transmitted, so that under the action of the transmission wheel 9, the yarn is quickly ejected from the nozzle 3 to the next process, and the yarn is stretched, thereby effectively improving the toughness of the yarn.
