Description

Technical Field

[0001] This utility model relates to the field of air-jet looms, and in particular to an air-jet loom air jet device. Background Technology

[0002] Air-jet looms use air jets to pull the yarn, using air to shuttle the yarn during processing. Different textile products have different requirements for weft insertion, so different tube diameters and lengths are needed, and the nozzles need to be replaced.

[0003] Existing technologies, such as the utility model patent with publication number CN220034810U, disclose an air jet device for an air jet loom. This patent changes the angle and speed of weft insertion by changing the air jet pipe of different lengths, by twisting and bending the pipe, and by changing the connecting pipe of different inner diameters, that is, by changing the inner diameter, length and angle of the air jet pipe. It has strong applicability, is convenient and quick to operate, improves production efficiency and reduces production costs.

[0004] However, this technology uses a snap-fit ​​method for fixing and installing the second connecting tube when it is replaced. Since there are gaps between the snap-fit ​​connections, the airflow will cause the snap-fit ​​connection to shake during the jet process, which will cause the gas to escape from the wrong path and thus affect the quality of the textile. Utility Model Content

[0005] The technical problem this invention aims to solve is that gaps exist between snap-fit ​​connections, causing the airflow to shake at the snap-fit ​​connection during the jetting process, which in turn causes deviations in the gas escape path and affects the quality of the textile.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: a jet device, including a support base, a base, and a second connecting pipe. A horn tube is provided on the inner wall of the support base. A first connecting pipe is fixedly connected to one side of the horn tube. A connecting device is provided between the first and second connecting pipes. A jet pipe is fixedly connected to one side of the second connecting pipe. An auxiliary spray seat is fixedly connected to one side of the horn tube. One side of the auxiliary spray seat is fixedly connected to one side of the support base. An air inlet pipe is passed through one side of the auxiliary spray seat. An adjustment device is provided between one side of the support base and one side of the base. The connecting device enables a more secure connection between the first and second connecting pipes, and the connection is more stable under inflation pressure during inflation, making disassembly and installation more convenient. The adjustment device can adjust the height of the support base and the entire jet device, improving its adaptability.

[0007] The effect achieved by the above components is as follows: When the air jet device is installed on an air jet loom, the second connecting pipe can be installed on the first connecting pipe through the connecting device, and then the height of the support can be adjusted by the adjusting device to facilitate the use of the air jet loom. When weaving, the yarn is first passed through the inner wall of the auxiliary spray seat, the trumpet tube, the first connecting pipe, the second connecting pipe and the air jet pipe, and then the air inlet pipe is connected to the air pump or other gas conveying equipment. When weaving, the gas enters the auxiliary spray seat through the air inlet pipe, and then blows into the inside of the trumpet tube and the air jet pipe to pull the yarn and cooperate with the air jet loom for weaving.

[0008] Preferably, the connecting device includes a threaded ring block, one side of which is fixedly connected to one side of the first connecting pipe. A plurality of grooves are formed on one side of the threaded ring block, and a plurality of limiting grooves are formed on the inner wall of the threaded ring block. One end of the second connecting pipe is inserted into the inner wall of the threaded ring block. A plurality of limiting blocks are fixedly connected to the outer surface of the second connecting pipe, and the limiting blocks are inserted into the inner wall of the limiting grooves. A tapered ring block is slidably connected to the outer surface of the second connecting pipe, and a threaded hole block is rotatably connected to one side of the tapered ring block. The inner wall of the threaded hole block is threadedly connected to the outer surface of the threaded ring block.

[0009] The effect achieved by the above components is as follows: When the second connecting pipe is installed on the first connecting pipe for use, one end of the second connecting pipe can be inserted into the inner wall of the threaded ring block, and several limiting blocks on its outer surface can be inserted into the inner wall of the limiting groove, with one side abutting against one side of the first connecting pipe. Then, the screw hole block is screwed into the threaded ring block in a certain direction to a certain position so that one side abuts against the outer surface of the threaded ring block against one side of the first connecting pipe, until the inner wall of the conical ring block abuts against one end of the threaded ring block, causing it to contract with the gap of the groove, thus fixing and limiting the second connecting pipe, thereby fixing the air jet pipe on the first connecting pipe, which is convenient for later textile use. Through the fixing of the screw hole block, conical ring block and threaded ring block, as well as the limiting of the limiting block and limiting groove, the connection between the first connecting pipe and the second connecting pipe can be made more secure, and the connection is less likely to shake or loosen when subjected to inflation pressure during the inflation process, making it more stable, and also convenient for disassembly and installation.

[0010] Preferably, a plurality of protrusions are fixedly connected to the outer surface of the screw hole block, and the plurality of protrusions are arranged at equal intervals.

[0011] The effect achieved by the above components is that by setting the protrusions, the contact friction of the outer surface of the screw hole block can be increased, making it easier to hold and tighten manually, and thus easier to operate.

[0012] Preferably, the inner wall of the conical ring block is rotatably connected with a plurality of ball bearings, and the plurality of ball bearings are disposed in the inner wall of the conical ring block at one end near the screw hole block.

[0013] The effect achieved by the above components is that by setting ball bearings, after the ball bearings abut against the inner wall of the tapered ring block on one side of the threaded ring block, the ball bearings can reduce the contact wear between the two and facilitate the shrinking and extrusion treatment.

[0014] Preferably, a sealing block is fixedly connected to one side of the screw hole block, and the sealing block is made of silicone.

[0015] The effect achieved by the above components is that, by setting a sealing block, after the screw hole block is screwed onto the outer surface of the threaded ring block, the gap between the screw hole block and one side of the first connecting pipe can be sealed and plugged, preventing air leakage and improving the airtightness of the connecting device.

[0016] Preferably, one side of the threaded ring block is provided with an angle.

[0017] The effect achieved by the above components is that by setting the bevel angle, the area at the entrance of the inner wall of the threaded ring block can be increased, making it easier for the second connecting pipe to be quickly aligned and inserted.

[0018] Preferably, the adjusting device includes an electric telescopic rod, a groove is provided on one side of the base, one side of the inner wall of the groove is fixedly connected to one end of the electric telescopic rod, a slider is fixedly connected to one side of the output rod of the electric telescopic rod, the slider is slidably connected to the groove, and one side of the slider is fixedly connected to one side of the support base.

[0019] The effect achieved by the above components is as follows: by setting the adjustment device, when the support base, the trumpet tube and the auxiliary spray base are installed on the air-jet loom, they can be fixed in the designated position by the base first. Then, according to the actual use needs, the electric telescopic rod is activated to drive the slider to slide up or down in the inner wall of the slide groove to a certain position, thereby driving the support base to move to a certain position, which facilitates the pulling of the yarn and improves the adaptability of use.

[0020] Preferably, a reinforcing rod is fixedly connected to the outer surface of the output rod of the electric telescopic rod, and one side of the reinforcing rod is fixedly connected to one side of the slider.

[0021] The effect achieved by the above components is that by setting up reinforcing rods, the connection area between the output rod of the electric telescopic rod and the slider can be increased, making the connection more solid and stable, and less prone to breakage and damage.

[0022] The beneficial effects of this utility model are:

[0023] By setting up a connecting device, and fixing it with screw hole blocks, conical ring blocks and threaded ring blocks, as well as limiting blocks and limiting grooves, the connection between the first connecting pipe and the second connecting pipe can be made more secure. During the inflation process, the connection is less likely to shake or loosen when subjected to inflation pressure, making it more stable. At the same time, it is also convenient to disassemble and install it, thus improving the quality of textiles. Attached Figure Description

[0032] Figure 1-4The air jet device of the air jet loom shown includes a support base 1, a base 10, and a second connecting pipe 6. A trumpet pipe 4 is provided on the inner wall of the support base 1. A first connecting pipe 5 is fixedly connected to one side of the trumpet pipe 4. A connecting device 2 is provided between the first connecting pipe 5 and the second connecting pipe 6. An air jet pipe 7 is fixedly connected to one side of the second connecting pipe 6. An auxiliary spray seat 8 is fixedly connected to one side of the trumpet pipe 4. One side of the auxiliary spray seat 8 is fixedly connected to one side of the support base 1. An air inlet pipe 9 is passed through and connected to one side of the auxiliary spray seat 8. An adjustment device 3 is provided between one side of the support base 1 and one side of the base 10. The connecting device 2 can make the connection between the first connecting pipe 5 and the second connecting pipe 6 more secure, and the connection is more stable when subjected to inflation pressure during inflation, making disassembly and installation more convenient. The adjustment device 3 can adjust the height of the support base 1 and the entire air jet device, improving the adaptability to use. When the air jet device is installed on an air jet loom, the second connecting pipe 6 can be first installed on the first connecting pipe 5 through the connecting device 2. Then, the height of the support base 1 can be adjusted through the adjusting device 3 to adapt to the air jet loom. When weaving, the yarn is first passed through the inner wall of the auxiliary spray base 8, the trumpet pipe 4, the first connecting pipe 5, the second connecting pipe 6 and the air jet pipe 7. Then, the air inlet pipe 9 is connected to the air pump or other equipment that transports gas. When weaving, the gas enters the auxiliary spray base 8 through the air inlet pipe 9 and is then blown into the inside of the trumpet pipe 4 and the air jet pipe 7 to pull the yarn and cooperate with the air jet loom for weaving.

[0033] Figure 1-4The connecting device 2 shown includes a threaded ring block 21. One side of the threaded ring block 21 is fixedly connected to one side of the first connecting pipe 5. Several grooves 22 are provided on one side of the threaded ring block 21. Several limiting grooves 23 are provided on the inner wall of the threaded ring block 21. One end of the second connecting pipe 6 is inserted into the inner wall of the threaded ring block 21. Several limiting blocks 26 are fixedly connected to the outer surface of the second connecting pipe 6. The limiting blocks 26 are inserted into the inner wall of the limiting grooves 23. A tapered ring block 25 is slidably connected to the outer surface of the second connecting pipe 6. A screw hole block 24 is rotatably connected to one side of the tapered ring block 25. The inner wall of the screw hole block 24 is threadedly connected to the outer surface of the threaded ring block 21. When the second connecting pipe 6 is installed on the first connecting pipe 5, one end of the second connecting pipe 6 can be inserted into the inner wall of the threaded ring block 21, and several limiting blocks 26 on its outer surface can be inserted into the inner wall of the limiting groove 23, with one side abutting against one side of the first connecting pipe 5. Then, the screw hole block 24 is screwed into the threaded ring block 21 in a certain direction to a certain position so that one side abuts against one side of the outer surface of the threaded ring block 21 against one side of the first connecting pipe 5, until the inner wall of the conical ring block 25 abuts against one end of the threaded ring block 21. The first connecting pipe 5 is fixed in place by the gap of the groove 22, which causes the second connecting pipe 6 to contract and thus fix the air jet pipe 7 to the first connecting pipe 5. This facilitates later textile use. The fixing of the screw hole block 24, the conical ring block 25 and the threaded ring block 21, as well as the limiting block 26 and the limiting groove 23, makes the connection between the first connecting pipe 5 and the second connecting pipe 6 more secure. During the inflation process, the connection is less likely to shake or loosen when subjected to inflation pressure, making it more stable. It also facilitates disassembly and installation.

[0034] Figure 1-4 The outer surface of the screw hole block 24 shown has several protrusions 27 fixedly connected to it, and these protrusions 27 are arranged at equal intervals. By setting the protrusions 27, the contact friction of the outer surface of the screw hole block 24 can be increased, making it easier to grip and tighten manually. The inner wall of the conical ring block 25 is rotatably connected to several balls 28, which are located in the inner wall of the conical ring block 25 near the end of the screw hole block 24. By setting the balls 28, after the threaded ring block 21 abuts against the inner wall of the conical ring block 25 on one side, the balls 28 can reduce the contact wear between the two, facilitating the shrinking and compression processing.

[0035] Figure 1-4A sealing block 29, made of silicone, is fixedly connected to one side of the screw hole block 24. By setting the sealing block 29, after the screw hole block 24 is screwed onto the outer surface of the threaded ring block 21, the gap between the screw hole block 24 and one side of the first connecting pipe 5 can be sealed, preventing air leakage and improving the airtightness of the connecting device 2. A chamfer 210 is provided on one side of the threaded ring block 21. By setting the chamfer 210, the area at the inlet of the inner wall of the threaded ring block 21 can be increased, making it easier for the second connecting pipe 6 to be quickly aligned and inserted.

[0036] Figure 1-4 The adjustment device 3 shown includes an electric telescopic rod 32. A groove 31 is provided on one side of the base 10. One side of the inner wall of the groove 31 is fixedly connected to one end of the electric telescopic rod 32. A slider 33 is fixedly connected to one side of the output rod of the electric telescopic rod 32. The slider 33 is slidably connected to the groove 31, and one side of the slider 33 is fixedly connected to one side of the support base 1. When the support base 1, the trumpet tube 4, and the auxiliary spray base 8 are installed on the air-jet loom, they can first be fixed in a designated position by the base 10. Then, according to actual usage requirements, the electric telescopic rod 32 is activated to drive the slider 33 to slide upwards or downwards in the inner wall of the groove 31 to a certain position, thereby moving the support base 1 to a certain position, facilitating the pulling of the yarn and improving adaptability. A reinforcing rod 34 is fixedly connected to the outer surface of the output rod of the electric telescopic rod 32, and one side of the reinforcing rod 34 is fixedly connected to one side of the slider 33. By setting the reinforcing rod 34, the connection area between the output rod of the electric telescopic rod 32 and the slider 33 can be increased, making the connection more secure and stable, and less prone to breakage or damage.

[0037] Working principle: When the air-jet device is installed on an air-jet loom, one end of the second connecting pipe 6 is inserted into the inner wall of the threaded ring block 21, and several limiting blocks 26 on its outer surface are respectively inserted into the inner wall of the limiting groove 23, with one side abutting against one side of the first connecting pipe 5. Then, the screw hole block 24 is screwed onto the threaded ring block 21 in a certain direction to a certain position so that one side abuts against one side of the first connecting pipe 5 on the outer surface of the threaded ring block 21, until the inner wall of the conical ring block 25 presses against one end of the threaded ring block 21. The contact mechanism causes the second connecting pipe 6 to contract via the gap in the groove 22, thus fixing the air jet pipe 7 onto the first connecting pipe 5. This facilitates later textile use. The fixing by the screw hole block 24, the conical ring block 25, and the threaded ring block 21, along with the limiting block 26 and the limiting groove 23, ensures a more secure connection between the first connecting pipe 5 and the second connecting pipe 6. Furthermore, during inflation, the connection is less prone to shaking or loosening under inflation pressure, resulting in greater stability and easier disassembly and installation. The pipe is then first fixed in a designated position by the base 10. Then, according to actual usage requirements, the electric telescopic rod 32 is activated, causing the slider 33 to slide upwards or downwards within the inner wall of the groove 31 to a certain position. This moves the support base 1 to a specific position, facilitating the pulling of the yarn and improving usability. During weaving, the yarn is first passed through the inner walls of the auxiliary spray seat 8, the trumpet tube 4, the first connecting pipe 5, the second connecting pipe 6, and the air jet pipe 7. Then, the air inlet pipe 9 is connected to the air pump or other equipment that transports gas. During weaving, the gas enters the auxiliary spray seat 8 through the air inlet pipe 9 and is then blown into the interior of the trumpet tube 4 and the air jet pipe 7 to pull the yarn and cooperate with the air jet loom for weaving.
