Description

Technical Field

[0001] This utility model relates to the field of textile processing technology, and in particular to an air jet device for an air jet loom. Background Technology

[0002] Air-jet looms are shuttleless looms that use jet airflow to guide the weft yarn through the shed. The working principle is to use air as the weft-guiding medium, with the compressed airflow generating frictional traction on the weft yarn to pull it through the shed. The jet of air achieves the purpose of weft insertion. However, different textile products have different requirements for weft insertion, including varying speeds, thus necessitating adjustments to the inner diameter and length of the air jet pipe.

[0003] Chinese utility model patent application number CN220034810U discloses an air jet device for an air-jet loom, including a vertical pole with a support base sleeved on it. An auxiliary spray seat is provided on one side of the support base, and an air inlet pipe is connected to the auxiliary spray seat. An air outlet pipe is installed on the other side of the support base. The air outlet pipe includes a trumpet tube, a bent tube, a connecting tube 1, and an air jet pipe connected end to end in sequence. The trumpet tube is bolted to the support base. The bent tube is conical in shape. The connecting tube 1 is detachably connected to the bent tube and threadedly connected to the air jet pipe. The bent tube and the connecting tube 1 are connected by an insertion joint. The connecting tube 1 is replaced by a beveled protrusion for locking. There are often gaps between the locked joints, resulting in poor airtightness of the air jet device connection and affecting the traction effect of the jet airflow on the weft yarn. Utility Model Content

[0004] The purpose of this invention is to provide an air jet device for an air jet loom, which has the effect of ensuring the airtightness of the air jet device connection.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: It includes a base, a nozzle, a support rod disposed on the base, and a first fixing tube disposed at the top of the support rod. An air inlet pipe is connected to the first fixing tube. A second fixing tube in the shape of a frustum is connected to one end of the first fixing tube. A third fixing tube is connected to the end of the second fixing tube. A first connecting tube is connected to one end of the third fixing tube. A second connecting tube is connected to the end of the nozzle. The outer diameter of the first connecting tube is equal to the outer diameter of the second connecting tube. An elastic sealing ring is sleeved between the first connecting tube and the second connecting tube. The inner wall of the elastic sealing ring is movably fitted to the outer walls of the first connecting tube and the second connecting tube. A connecting member for pressing the elastic sealing ring is movably disposed on the first connecting tube. A fixing member for fixing the connecting member is disposed on the support rod.

[0006] A further feature of this invention is that the connecting component includes a connecting cylinder and a clamping block with an arc-shaped cross-section symmetrically and movably disposed within the connecting cylinder. A connecting rod is symmetrically threaded onto the connecting cylinder, and the end of the connecting rod is fixedly connected to the outer wall of the clamping block. The inner diameter of the connecting cylinder is larger than the outer diameter of the elastic sealing ring. The longitudinal cross-section of the clamping block is semi-circular, and the inner diameter of the clamping block is smaller than the outer diameter of the elastic sealing ring. The inner diameter of the clamping block is larger than the outer diameter of the first connecting pipe.

[0007] A further feature of this invention is that: a plurality of annular first connecting grooves are uniformly formed on the outer wall of the end of the first connecting tube near the second connecting tube, and a plurality of annular second connecting grooves are uniformly formed on the outer wall of the end of the second connecting tube away from the nozzle.

[0008] A further feature of this invention is that a third connecting pipe is provided at the end of the second connecting pipe, and the outer wall of the third connecting pipe is movably fitted to the inner wall of the first connecting pipe.

[0009] A further feature of this invention is that a plurality of third connecting grooves are horizontally formed on the inner wall of the first connecting pipe near the end of the second connecting pipe, and a plurality of limiting blocks that can cooperate with the third connecting grooves are provided on the outer wall of the third connecting pipe.

[0010] A further feature of this invention is that the fixing member includes a support block horizontally disposed on the support rod and a fixing rod threadedly connected to the support block in a vertical direction, wherein the top end of the fixing rod is threadedly connected to the bottom end of the connecting cylinder.

[0011] A further feature of this invention is that a first rotating rod is provided at the bottom end of the fixed rod.

[0012] A further feature of this invention is that a second rotating rod is provided at the end of the connecting rod away from the clamping block.

[0013] The beneficial effects of this utility model are:

[0014] 1. By setting up elastic sealing rings and connectors, when installing the nozzle, first insert one end of the second connecting tube into the elastic sealing ring until the second connecting tube abuts against the end of the first connecting tube. Then, use the connectors to press the elastic sealing ring tightly, so that the elastic sealing ring fits tightly against the first and second connecting tubes. Therefore, by setting up elastic sealing rings and connectors, the airtightness of the connection between the first and second connecting tubes can be ensured by the connectors pressing the elastic sealing ring. The operation is simple and convenient, and it is easy to replace the nozzle according to practical needs. At the same time, it ensures the airtightness of the nozzle connection of the paint spraying device and ensures the traction effect of the spray airflow on the weft yarn. By setting up fixing parts, the connectors are fixed, thereby improving the stability of the connection between the first and second connecting tubes and the support column, and preventing the second connecting tube from shaking when the air spraying device sprays high-speed airflow.

[0015] 2. By setting up connecting cylinders and clamping blocks, when it is necessary to remove the second connecting pipe, rotate the connecting rods on both sides so that the two clamping blocks move away from the elastic sealing ring. Then, the second connecting pipe and nozzle can be removed directly. When it is necessary to fix the second connecting pipe, insert the end of the second connecting pipe into the elastic sealing ring until the second connecting pipe touches the first connecting pipe. Then rotate the connecting rods on both sides so that the clamping blocks on both sides approach and squeeze the elastic sealing ring until the two clamping blocks touch each other. Since the inner diameter of the clamping block is slightly smaller than the outer diameter of the elastic sealing ring, and the clamping block is semi-circular, the elastic sealing ring is compressed when the two clamping blocks touch each other, thereby ensuring the airtightness of the connection between the elastic sealing ring and the first and second connecting pipes. At the same time, the connection between the first and second connecting pipes is achieved by rotating the connecting rods. The operation is simple and convenient.

[0016] 3. By setting up support blocks and fixing rods, the elastic sealing ring is prone to deformation after long-term compression. When it is necessary to replace the elastic sealing ring, simply rotate the fixing rod to separate it from the connecting cylinder. Then rotate the two connecting rods to separate the clamping block from the elastic sealing ring. After that, the connecting cylinder, the second connecting pipe, and the elastic sealing ring can be removed in sequence. Finally, a new elastic sealing ring can be put on. The operation is simple and convenient. The fixing rod enables a detachable connection between the connecting cylinder and the support rod. The connection between the second connecting pipe and the support rod can be increased through the elastic sealing ring, clamping block, and connecting cylinder, thereby improving the stability of the second connecting pipe and the first connecting pipe, and at the same time facilitating the replacement of the elastic sealing ring.

Detailed Implementation

[0024] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] This utility model provides an air jet device for an air jet loom, such as... Figures 1 to 5As shown, the device includes a base 1, a nozzle 2, a support rod 3 mounted on the base 1, and a first fixing tube 4 mounted on the top of the support rod 3. An air inlet pipe 5 is connected to the first fixing tube 4. A second fixing tube 6 in the shape of a frustum is connected to one end of the first fixing tube 4. A third fixing tube 7 is connected to the end of the second fixing tube 6. A first connecting tube 8 is connected to one end of the third fixing tube 7. A second connecting tube 9 is connected to the end of the nozzle 2. The outer diameter of the first connecting tube 8 is equal to the outer diameter of the second connecting tube 9. An elastic sealing ring 10 is sleeved between the first connecting tube 8 and the second connecting tube 9. The inner wall of the elastic sealing ring 10 can be movably fitted to the outer walls of the first connecting tube 8 and the second connecting tube 9. A connecting member 11 for pressing the elastic sealing ring 10 is movably mounted on the first connecting tube 8. A fixing member 12 for fixing the connecting member 11 is mounted on the support rod 3.

[0026] Furthermore, the connector 11 includes a connecting cylinder 11a and a clamping block 11b with an arc-shaped cross-section symmetrically and movably disposed within the connecting cylinder 11a. A connecting rod 13 is symmetrically threaded onto the connecting cylinder 11a. The end of the connecting rod 13 is fixedly connected to the outer wall of the clamping block 11b. The inner diameter of the connecting cylinder 11a is larger than the outer diameter of the elastic sealing ring 10. The longitudinal section of the clamping block 11b is semi-circular. The inner diameter of the clamping block 11b is smaller than the outer diameter of the elastic sealing ring 10. The inner diameter of the clamping block 11b is larger than the outer diameter of the first connecting pipe 8.

[0027] Furthermore, a plurality of annular first connecting grooves 14 are uniformly formed on the outer wall of the first connecting pipe 8 near the second connecting pipe 9, and a plurality of annular second connecting grooves 15 are uniformly formed on the outer wall of the second connecting pipe 9 away from the nozzle 2.

[0028] Furthermore, a third connecting pipe 16 is provided at the end of the second connecting pipe 9, and the outer wall of the third connecting pipe 16 can be movably attached to the inner wall of the first connecting pipe 8.

[0029] Furthermore, a plurality of third connecting grooves 17 are horizontally opened on the inner wall of the first connecting pipe 8 near the second connecting pipe 9, and a plurality of limiting blocks 18 that can cooperate with the third connecting grooves 17 are provided on the outer wall of the third connecting pipe 16.

[0030] Furthermore, the fixing member 12 includes a support block 12a horizontally disposed on the support rod 3 and a fixing rod 12b threadedly connected to the support block 12a in the vertical direction, wherein the top end of the fixing rod 12b is threadedly connected to the bottom end of the connecting cylinder 11a.

[0031] Furthermore, a first rotating rod 19 is provided at the bottom end of the fixed rod 12b.

[0032] Furthermore, a second rotating rod 20 is provided at the end of the connecting rod 13 away from the clamping block 11b.

[0033] When installing nozzle 2, first insert one end of the second connecting pipe 9 into the elastic sealing ring 10 until the second connecting pipe 9 abuts against the end of the first connecting pipe 8. Then, by rotating the two connecting rods 13, drive the clamping block 11b to press the elastic sealing ring 10 until the two clamping blocks 11b abut against each other, so that the elastic sealing ring 10 fits tightly against the first connecting pipe 8 and the second connecting pipe 9, thereby realizing the installation of the second connecting pipe 9 and nozzle 2. Therefore, by setting the elastic sealing ring 10, connecting parts 11, etc., the connecting parts 11 can press the elastic sealing ring 10 to ensure the airtightness of the connection between the first connecting pipe 8 and the second connecting pipe 9. The operation is simple and convenient, and it is easy to replace the nozzle 2 according to practical needs. At the same time, it ensures the airtightness of the connection of the nozzle 2 of the painting device and ensures the traction effect of the spray airflow on the weft yarn.

[0034] By setting the fixing component 12, the connecting component 11 is fixed, thereby improving the stability of the connection between the first connecting pipe 8 and the second connecting pipe 9 and the support column, and preventing the second connecting pipe 9 from shaking when the jet device sprays high-speed airflow.

[0035] By setting up connecting cylinder 11a, clamping blocks 11b, etc., when the second connecting pipe 9 needs to be removed, rotate the connecting rods 13 on both sides so that the two clamping blocks 11b are respectively away from the elastic sealing ring 10, and then the second connecting pipe 9 and nozzle 2 can be directly removed outwards; when the second connecting pipe 9 needs to be fixed, insert the end of the second connecting pipe 9 into the elastic sealing ring 10 until the second connecting pipe 9 abuts against the first connecting pipe 8, and then rotate the connecting rods 13 on both sides so that the clamping blocks 11b on both sides approach and squeeze the elastic sealing ring 10 until the two clamping blocks 11b abut against each other. Since the inner diameter of the clamping block 11b is slightly smaller than the outer diameter of the elastic sealing ring 10, and the clamping block 11b is semi-circular, the elastic sealing ring 10 is in a compressed state when the two clamping blocks 11b abut against each other, thereby ensuring the airtightness of the connection between the elastic sealing ring 10 and the first connecting pipe 8 and the second connecting pipe 9. At the same time, the connection between the first connecting pipe 8 and the second connecting pipe 9 is achieved by rotating the connecting rod 13. The operation is simple and convenient.

[0036] By setting the first connecting groove 14 and the second connecting groove 15, as the pressing block 11b approaches the elastic sealing ring 10, it pushes the elastic sealing ring 10 to deform, so that the inner side of the elastic sealing ring 10 is tightly attached to the first connecting groove 14 and the second connecting groove 15, thereby further improving the airtightness between the first connecting pipe 8 and the second connecting pipe 9.

[0037] By setting the third connecting groove 17 and the limiting block 18, the contact area between the second connecting pipe 9 and the first connecting pipe 8 is increased, thereby further increasing the fixing effect on the second connecting pipe 9.

[0038] By setting up the support block 12a and the fixing rod 12b, since the elastic sealing ring 10 is prone to deformation after long-term compression, when it is necessary to replace the elastic sealing ring 10, simply rotate the fixing rod 12b to separate the fixing rod 12b from the connecting cylinder 11a. Then rotate the two connecting rods 13 to separate the clamping block 11b from the elastic sealing ring 10. After that, the connecting cylinder 11a, the second connecting pipe 9, and the elastic sealing ring 10 can be removed in sequence. Finally, a new elastic sealing ring 10 can be put on. The operation is simple and convenient. The fixing rod 12b realizes the detachable connection between the connecting cylinder 11a and the support rod 3. The connection between the second connecting pipe 9 and the support rod 3 can be increased by the elastic sealing ring 10, the clamping block 11b, and the connecting cylinder 11a, thereby improving the stability of the second connecting pipe 9 and the first connecting pipe 8, and at the same time facilitating the replacement of the elastic sealing ring 10.

[0039] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
