Description

Technical Field

[0001] The utility model relates to the technical field of air-jet looms, and particularly relates to an auxiliary nozzle for an air-jet loom. Background Art

[0002] An air-jet loom is a shuttleless loom that uses a jet of air to draw the weft thread through the shed. Its working principle is to use air as the weft insertion medium, and use the compressed air jet to generate frictional traction on the weft yarn to draw it, and bring the weft yarn through the shed to achieve the purpose of weft insertion by the jet generated by the air jet.

[0003] At present, the auxiliary nozzles of air-jet looms cannot change the direction of the air jet according to the needs of textiles, and most nozzles are installed by threading. Once the installation direction is incorrect, it is necessary to screw them out, readjust the direction and then screw them in again, which is rather troublesome. Moreover, the nozzles will generate quite a lot of noise during use. Therefore, an auxiliary nozzle for an air-jet loom is proposed, which can conveniently change the direction of the nozzle and provide a certain noise reduction effect. Summary of the Utility Model

[0004] Aiming at the problems in the prior art, the utility model provides an auxiliary nozzle for an air-jet loom, which can conveniently change the direction of the nozzle and provide a certain noise reduction effect.

[0005] The technical solution adopted by the utility model to solve its technical problems is an auxiliary nozzle for an air-jet loom, which includes an installation table. A turntable is rotatably installed at the top end of the installation table. A bearing is sleeved on the lower part of the outer side of the turntable, and the bearing is installed inside the installation table. The center of the top surface of the turntable is threadedly connected with a threaded pipe. The top end of the threaded pipe is fixedly connected with the bottom end of a connecting pipe and is internally communicated. The top end of the connecting pipe is fixedly connected with the bottom end of the nozzle and is internally communicated. A sound insulation sleeve is sleeved on the outer side of the nozzle, and an air outlet hole is opened on one side of the sound insulation sleeve.

[0006] By adopting the above technical solution, the setting of the turntable can adjust the direction of the nozzle that has been fixedly installed, avoiding the troublesome operation of repeatedly disassembling the nozzle, and enabling the nozzle to freely adjust the air jet direction according to the needs of textiles.

[0007] By sleeving the sound insulation sleeve on the nozzle, the transmission of the sound of the air flow flowing inside the nozzle can be reduced, thereby providing a certain sound insulation and noise reduction effect for the nozzle.

[0008] Specifically, an air source is fixedly installed inside the turntable, and an air inlet pipe is provided at the top end of the air source. The top end of the air inlet pipe is inserted into the bottom end of the threaded pipe and is internally communicated.

[0009] By adopting the above technical solution, when installing the threaded pipe, the top end of the air inlet pipe needs to be aligned with the center of the bottom end of the threaded pipe, which facilitates inserting the air inlet pipe into the bottom end of the threaded pipe, enabling the air inlet pipe to communicate with the inside of the threaded pipe and allowing the air source to jet air for the nozzle through the air inlet pipe.

[0010] Specifically, bolts are installed on opposite sides of the installation table. One end of the bolt close to the turntable is fixedly connected to one end of the rotating rod, and the other end of the rotating rod is rotatably connected to one side of the arc-shaped clamping plate. A rubber layer is fixedly pasted on the side of the arc-shaped clamping plate close to the turntable.

[0011] By adopting the above technical solution, after the direction of the nozzle is adjusted, the two arc-shaped clamping plates in the cavity are made to approach the outside of the turntable by screwing the bolts on both sides of the installation table, thereby clamping and fixing the turntable with the two arc-shaped clamping plates.

[0012] Specifically, a cavity is provided inside the installation table, and there are two opposite cavities, both of which are used for the left and right movement of the arc-shaped clamping plates.

[0013] By adopting the above technical solution, the arc-shaped clamping plate is in the cavity and moves left and right by screwing the bolt.

[0014] Specifically, a fixing block is fixedly connected to the lower part of the outer side of the sound insulation sleeve. The bottom end of the fixing block is in contact with the top end of the connecting pipe, and the fixing block and the connecting pipe are fixedly connected by self-tapping screws.

[0015] By adopting the above technical solution, the sound insulation sleeve can be fixed by passing the self-tapping screws through the fixing block and the top end of the connecting pipe in sequence, and the self-tapping screws will not penetrate into the inside of the connecting pipe, avoiding air leakage.

[0016] The beneficial effects of the present utility model:

[0017] (1) For the auxiliary nozzle of the air-jet loom described in the present utility model, the direction of the already fixedly installed nozzle can be adjusted through the setting of the turntable, avoiding the troublesome operation of repeatedly disassembling the nozzle, and enabling the nozzle to freely adjust the jetting direction according to the requirements of the textile.

[0018] (2) For the auxiliary nozzle of the air-jet loom described in the present utility model, by sleeving the sound insulation sleeve on the nozzle, the propagation of the sound of the airflow flowing inside the nozzle can be reduced, thereby providing a certain sound insulation and noise reduction effect for the nozzle.

Specific embodiments

[0025] In order to make the technical means, creative features, achieved purposes and effects realized by the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.

[0026] In order to conveniently change the direction of the nozzle and provide a certain noise reduction effect, as an embodiment of the utility model, as Figures 1 - 4 shown, an auxiliary nozzle for an air-jet loom according to the utility model includes a mounting table 1, a turntable 2 is rotatably mounted on the top end of the mounting table 1, a bearing 14 is sleeved on the lower part of the outer side of the turntable 2, the bearing 14 is installed inside the mounting table 1, the center of the top surface of the turntable 2 is threadedly connected to a threaded pipe 8, the top end of the threaded pipe 8 is fixedly connected to the bottom end of a connecting pipe 3 and is internally connected, the top end of the connecting pipe 3 is fixedly connected to the bottom end of a nozzle 9 and is internally connected, a sound insulation sleeve 5 is sleeved on the outer side of the nozzle 9, and an air outlet hole 6 is formed on one side of the sound insulation sleeve 5.

[0027] During use, the threaded pipe 8 is inserted into the center of the top end of the turntable 2 by threading. According to the needs of the textile, the turntable 2 is rotated. The turntable 2 can rotate through the sleeving of the bearing 14 to adjust the direction of the nozzle 9. The sound insulation sleeve 5 is sleeved on the nozzle 9, and the air outlet hole 6 of the sound insulation sleeve 5 is aligned with the air jet port of the nozzle 9, which can provide a certain noise reduction and sound insulation effect for the nozzle 9. The sound insulation sleeve 5 is internally provided with sound insulation materials.

[0028] Exemplarily, as Figures 1 - 4 shown, the present utility model further includes that a gas source 11 is fixedly installed inside the turntable 2, an intake pipe 10 is provided at the top end of the gas source 11, and the top end of the intake pipe 10 is inserted into the bottom end of the threaded pipe 8 and is internally connected.

[0029] During use, when installing the threaded pipe 8, the top end of the air inlet pipe 10 needs to be aligned with the center of the bottom end of the threaded pipe 8, which facilitates inserting the air inlet pipe 10 into the bottom end of the threaded pipe 8, enabling the air inlet pipe 10 to communicate with the inside of the threaded pipe 8, and allowing the air source 11 to jet air for the nozzle 9 through the air inlet pipe 10.

[0030] Exemplarily, as Figures 1 - 4 shown, the present utility model further includes that bolts 7 are installed on opposite sides of the mounting table 1. One end of the bolt 7 close to the turntable 2 is fixedly connected to one end of the rotating rod 16, and the other end of the rotating rod 16 is rotatably connected to one side of the arc-shaped clamping plate 12. A rubber layer 15 is fixedly adhered to the side of the arc-shaped clamping plate 12 close to the turntable 2.

[0031] During use, after the direction of the nozzle 9 is adjusted, the bolts 7 on both sides of the mounting table 1 are turned to make the two arc-shaped clamping plates 12 in the cavity 13 approach the outside of the turntable 2, thereby enabling the two arc-shaped clamping plates 12 to clamp and fix the turntable 2;

[0032] It should be noted that turning the bolt 7 can make the bolt 7 move towards the inside of the mounting table 1. Through the connection of the rotating rod 16, the bolt 7 will only drive the rotating rod 16 to rotate during the turning process, and will not drive the arc-shaped clamping plate 12 to rotate, but will drive the arc-shaped clamping plate 12 to approach the turntable 2, thereby clamping the turntable 2. The setting of the rubber layer 15 can increase the friction between the arc-shaped clamping plate 12 and the turntable 2, and the outside of the turntable 2 can be set to be a bit rougher to also increase the friction between the two.

[0033] Exemplarily, as Figures 1 - 4 shown, the present utility model further includes that a cavity 13 is provided inside the mounting table 1. There are two opposite cavities 13, and both cavities 13 are used for allowing the arc-shaped clamping plate 12 to move left and right.

[0034] During use, the arc-shaped clamping plate 12 is in the cavity 13 and moves left and right by turning the bolt 7.

[0035] Exemplarily, as Figures 1 - 4 shown, the present utility model further includes that a fixing block 4 is fixedly connected to the lower part of the outer side of the sound insulation sleeve 5. The bottom end of the fixing block 4 is in contact with the top end of the connecting pipe 3, and the fixing block 4 and the connecting pipe 3 are fixedly connected by self-tapping screws.

[0036] During use, the sound insulation sleeve 5 can be fixed by passing self-tapping screws through the fixing block 4 and the top end of the connecting pipe 3 in sequence, and the self-tapping screws will not penetrate into the inside of the connecting pipe 3, avoiding air leakage.

[0037] When the utility model is in use, first insert the threaded pipe 8 into the center of the top end of the turntable 2 through threads. When installing, the top end of the air inlet pipe 10 needs to be aligned with the center of the bottom end of the threaded pipe 8 to facilitate inserting the air inlet pipe 10 into the bottom end of the threaded pipe 8, so that the air inlet pipe 10 is communicated with the inside of the threaded pipe 8. Subsequently, rotate the turntable 2 according to the needs of the textile. The turntable 2 can rotate through the socket of the bearing 14 to adjust the direction of the nozzle 9. After the adjustment is completed, turn the bolts 7 on both sides of the mounting table 1 to make the two arc-shaped clamping plates 12 in the cavity 13 approach the outside of the turntable 2, so that the two arc-shaped clamping plates 12 clamp and fix the turntable 2. Finally, put the sound insulation sleeve 5 on the nozzle 9, align the air outlet hole 6 of the sound insulation sleeve 5 with the air jet port of the nozzle 9, and fix the sound insulation sleeve 5 by sequentially passing self-tapping screws through the fixing block 4 and the top end of the connecting pipe 3.
