[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; the compressed airflow generated by the jet creates frictional traction on the weft yarn, pulling it through the shed. The jet of air achieves the purpose of weft insertion.

[0003] However, when the inventors implemented this device, they found the following defects: the nozzle angle of the existing air-jet loom is three-quarters two degrees, the airflow utilization rate is not high, and in the traditional design, the operating lever and the gauge are independent components, which need to be used together when adjusting, and it is easy for a single component to be lost. Utility Model Content

[0004] Based on this, it is necessary to address the aforementioned technical problems. The nozzle angle of existing air-jet looms is three-quarters and two degrees, resulting in low airflow utilization. Furthermore, in traditional designs, the operating lever and the gauge are independent components, requiring combined use for adjustment, which can easily lead to the loss of a single component.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A novel nozzle for an air-jet loom includes a gauge, an operating lever above the gauge, and a scale on the surface of the gauge. The nozzle is adjusted to 4 / 2 of the scale. A positioning post is provided at the end of the gauge, and a swing post is provided at the top of the operating lever. Both the swing post and the positioning post have grooves at their bottom ends. A connecting mechanism is connected between the two grooves. The connecting mechanism includes a connecting steel rope and two connecting frames. The two connecting frames respectively cooperate with the two grooves. A connecting hole is provided at the end of each connecting frame, and both ends of the connecting steel rope are connected to the two connecting holes respectively.

[0006] In a preferred embodiment of the novel air-jet loom nozzle provided by this utility model, a clamping block is slidably installed inside the connecting frame, rectangular grooves are opened on both sides inside the connecting frame, a crossbar is provided at the opening of the connecting frame, and the two ends of the crossbar are respectively set in the two rectangular grooves, and one end of the crossbar is fixedly connected to the rectangular groove through a rotating shaft.

[0007] In a preferred embodiment of the novel air-jet loom nozzle provided by this utility model, a gear is connected to the top end of the shaft at the end of the crossbar. The gear is located above the crossbar, and a push rod is movably arranged on the side of the gear. A rack is provided at the end of the push rod near the opening of the connecting frame, and the rack meshes with the gear.

[0008] In a preferred embodiment of the novel air-jet loom nozzle provided by this utility model, a mating plate is fixedly provided behind the push rod, and a mating hole is provided on the surface of the mating plate. A swing rod is provided below the mating plate, and the middle part of the swing rod is connected to the inner wall of the rectangular groove through a rotating shaft. A protruding post is provided at the top of the swing rod, and the protruding post is movably installed into the mating hole.

[0009] In a preferred embodiment of the novel air-jet loom nozzle provided by this utility model, a first spring is provided at the bottom of the swing rod, and the other end of the first spring is connected to the inner wall of the rectangular groove away from the opening of the connecting frame.

[0010] In a preferred embodiment of the novel air-jet loom nozzle provided by this utility model, a sliding block is provided at the end of the clamping block, and the sliding block is slidably installed in the rectangular groove.

[0011] In a preferred embodiment of the novel air-jet loom nozzle provided by this utility model, an extension column is fixedly installed at the bottom of the swing rod, and the extension column is located in the moving path of the sliding block.

[0012] In a preferred embodiment of the novel jet loom nozzle provided by this utility model, an arc-shaped groove is provided on the surface of the clamping block near the opening of the connecting frame, and the arc-shaped groove corresponds to the inner wall of the groove.

The crossbar blocks the opening of the connecting frame, and the clamping block presses against the groove to form a double lock. After the crossbar is reset, it can effectively prevent the connecting frame from separating from the groove. Under the action of the second spring, the clamping block is pressed tightly against the outer wall of the groove, further enhancing the stability of the connection. This ensures that the connection between the operating lever and the gauge will not loosen due to vibration or other factors during the operation of the air-jet loom, and the operating lever and gauge are not easy to lose. The operator only needs to press the connecting frame towards the groove to trigger the connection mechanism. The crossbar will automatically rotate to open the opening. After the groove is inserted, the crossbar will reset to complete the connection. No complicated manual operation steps are required, which reduces the difficulty of operation and improves the installation efficiency. When disassembly is required, continue to press the groove to make the sliding block contact the extension column, triggering the swing arm to rotate, which in turn moves the push rod. The crossbar rotates again to open the opening. At this point, pull the connecting frame backward to remove the groove. The disassembly process is simple and quick, facilitating equipment maintenance and repair. Attached Figure Description

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] As described in the background art, the nozzle angle of existing air-jet looms is three-quarters two degrees, resulting in low airflow utilization. Furthermore, in traditional designs, the operating lever and the gauge are independent components, requiring combined use for adjustment, which can easily lead to the loss of a single component.

[0021] To solve this technical problem, this utility model provides a novel nozzle for an air-jet loom, which includes a gauge 1, an operating lever 2 above the gauge 1, a scale 4 on the surface of the gauge 1, and the nozzle being adjusted to the fourth mark and second degree of the scale 4. A positioning post is provided at the end of the gauge 1, and a swing post 3 is provided at the top of the operating lever 2. The bottom ends of the swing post 3 and the positioning post are both provided with grooves. A connecting mechanism 5 is connected between the two grooves. The connecting mechanism 5 includes a connecting steel rope 6 and two connecting frames 7. The two connecting frames 7 respectively cooperate with the two grooves. A connecting hole 8 is provided at the end of the connecting frame 7, and the two ends of the connecting steel rope 6 are respectively connected to the two connecting holes 8.

[0022] By adjusting the angle between scale 4 and the nozzle to 4.2 degrees, the airflow utilization rate can be significantly improved, the optimal flight angle of the yarn can be achieved, and the goal of saving air and improving efficiency can be achieved. Furthermore, under the action of the connecting mechanism 5, the operating lever 2 and the gauge 1 can be connected. The operating lever 2 and the gauge 1 are not easy to lose, and it is convenient to use them in combination. At the same time, the connection is strong and can ensure that the connection between the operating lever 2 and the gauge 1 will not loosen due to vibration or other factors during the operation of the air-jet loom.

[0023] Example 1 Please refer to Figure 1-6 : A clamping block 9 is slidably installed inside the connecting frame 7. Rectangular slots are opened on both sides inside the connecting frame 7. A crossbar 10 is provided at the opening of the connecting frame 7. The two ends of the crossbar 10 are respectively set in two rectangular slots. One end of the crossbar 10 is fixedly connected to the rectangular slot through a rotating shaft. Rectangular slots are formed on both sides inside the connecting frame 7. The two ends of the crossbar 10 are embedded in the rectangular slots, and one end is fixedly connected to the rectangular slot through a pivot, forming a rotatable fulcrum. The clamping block 9 is installed inside the connecting frame 7 and can slide along the direction of the rectangular slot. When the connecting frame 7 is aligned with the groove, the operator presses the connecting frame 7 towards the groove to start the connection mechanism. The crossbar 10 is subjected to pressure and rotates around the pivot. The other end of the crossbar 10 moves inside the connecting frame 7. The entire crossbar 10 moves into the rectangular slot with the pivot end. The opening of the connecting frame 7 is open, and the groove is engaged inside the connecting frame 7. Then the groove presses the clamping block 9 to leave space for the crossbar 10 to move. The crossbar 10 then resets around the pivot and covers the opening of the connecting frame 7 again, completing the connection between the connecting frame 7 and the groove.

[0024] Example 2 Further optimizations to Example 1, specifically, such as... Figure 3-6 As shown: A gear 11 is connected to the top of the shaft at the end of the crossbar 10. The gear 11 is located above the crossbar 10. A push rod 12 is movably arranged on the side of the gear 11. A rack 13 is provided at the end of the push rod 12 near the opening of the connecting frame 7. The rack 13 meshes with the gear 11. The crossbar 10 is stationary with the pivot as the fulcrum. The gear 11 is fixed at the top of the pivot and is engaged with the rack 13. The push rod 12 is close to the opening end of the connecting frame 7. The rack 13 is embedded in the tooth groove of the gear 11 to form a complete transmission chain. When the push rod 12 moves outward to the connecting frame 7, the rack 13 drives the gear 11 to rotate. The rotation of the gear 11 synchronously drives the crossbar 10 to rotate with the pivot as the fulcrum, causing the non-pivot end of the crossbar 10 to move inward to the connecting frame 7, opening the opening.

[0025] A mating plate 14 is fixedly installed behind the push rod 12. A mating hole 15 is opened on the surface of the mating plate 14. A swing rod 16 is installed below the mating plate 14. The middle part of the swing rod 16 is connected to the inner wall of the rectangular groove through a rotating shaft. A protruding post is provided at the top of the swing rod 16. The protruding post is movably installed into the mating hole 15. The push rod 12 is in its initial position, the crossbar 10 horizontally blocks the opening of the connecting frame 7, the mating plate 14 is fixed behind the push rod 12, the mating hole 15 is connected to the protrusion at the top of the swing rod 16, the protrusion is naturally embedded in the mating hole 15, the swing rod 16 remains stationary with the central pivot as the fulcrum, when the bottom of the swing rod 16 moves away from the opening of the connecting frame 7, it rotates with the central pivot as the fulcrum, the top of the swing rod 16 will drive the mating plate 14 to move to the other end through the mating hole 15, thereby pushing the entire push rod 12 to move outward of the connecting frame 7.

[0026] A first spring 17 is provided at the bottom of the swing arm 16, and the other end of the first spring 17 is connected to the inner wall of the rectangular groove away from the opening of the connecting frame 7. The bottom of the swing rod 16 is connected to the inner wall of the rectangular groove through the first spring 17. The first spring 17 is in a naturally extended state. The top protrusion of the swing rod 16 is embedded in the mating hole 15. The crossbar 10 horizontally blocks the opening of the connecting frame 7. At this time, the first spring 17 applies a pulling force to the bottom of the swing rod 16 toward the inside of the opening of the connecting frame 7 to maintain the initial locking of the system.

[0027] The end of the clamping block 9 is provided with a sliding block 19, which is slidably installed in the rectangular groove; The sliding block 19 at the end of the clamping block 9 is embedded in the rectangular groove inside the connecting frame 7. The sliding block 19 forms a clearance fit with the inner wall of the rectangular groove, allowing the sliding block 19 to slide linearly along the length of the groove while limiting radial wobble.

[0028] An extension post 18 is fixedly installed at the bottom of the swing arm 16, and the extension post 18 is located in the moving path of the sliding block 19; When the clamping block 9 moves into the connecting frame 7, the sliding block 19 slides synchronously along the rectangular groove until it reaches the last end. The sliding block 19 contacts and squeezes the extension column 18. The squeezing force is transmitted to the swing rod 16 through the extension column 18, causing it to rotate around the central pivot. The rotation of the swing rod 16 drives the top protrusion to move in the mating hole 15, pushing the mating plate 14 and the push rod 12 to move outward from the connecting frame 7.

[0029] Example 3 Further optimizations to Example 2, such as Figure 3-6 As shown: An arc-shaped groove is provided on the surface of the clamping block 9 near the opening of the connecting frame 7, and the arc-shaped groove corresponds to the inner wall of the groove. Curved surface contact disperses concentrated force into uniform surface pressure, avoiding local overload deformation of the groove, and can adapt to the micro-undulations of the groove surface, improving clamping reliability.

[0030] The other end of the clamping block 9 is provided with a second spring 20, and the other end of the second spring 20 is connected to the connecting frame 7; When the groove is engaged with the connecting frame 7, the outer wall of the groove presses the clamping block 9 to move into the connecting frame 7, and the second spring 20 is further compressed. The elastic buffering effect of the second spring 20 causes the pressing force to rise slowly, avoiding damage to the components caused by rigid collision. After the groove is fully engaged, the restoring force of the second spring 20 pushes the clamping block 9 to press tightly against the outer wall of the groove.

[0031] An arrow is provided on the end face of the operating lever 2, and the arrow mates with the scale 4; When the control lever 2 is swung, the arrow rotates or moves synchronously with the control lever 2, forming a real-time position indication on the scale 4. The operator can quickly confirm the nozzle angle or displacement parameters by visually observing the relative position of the arrow and the scale 4.

[0032] The usage process of the novel air-jet loom nozzle provided by this utility model is as follows: First, the scale 4 on the surface of the gauge 1 is preset to the fourth mark and second degree. The arrow on the end face of the operating lever 2 is aligned with this scale to determine the initial working angle of the nozzle. Next, the groove openings of the positioning column and the swing column 3 are aligned, and the two connecting frames 7 of the connecting mechanism 5 are aligned with the grooves respectively. The two ends of the connecting steel rope 6 are inserted into the connecting holes 8, and are in a ready-to-connect state. Then, the operator presses the connecting frame 7 towards the groove. The edge of the groove pushes the push rod 12 to move outward. The push rod 12 drives the rack 13 to slide, and the gear 11 rotates clockwise, simultaneously driving the crossbar 10 to rotate around the pivot point, opening the opening of the connecting frame 7. After the opening is open, the groove is inserted into the interior of the connecting frame 7. The inner wall of the groove presses the clamping block 9 to move inward. The sliding block 19 slides along the rectangular groove to a position close to the rear, but does not contact the extension column 18, leaving space for the crossbar 10 to move. Rod 10 then resets around the pivot, and the crossbar 10 covers the opening of the connecting frame 7 again, completing the connection between the connecting frame 7 and the groove. Finally, the groove is pressed further. When the clamping block 9 moves to its limit position, the sliding block 19 contacts and presses the extension column 18. The pressing force is transmitted to the swing rod 16 through the extension column 18, causing it to rotate around the central pivot. The rotation of the swing rod 16 drives the top protrusion to move within the mating hole 15, pushing the mating plate 14 and the push rod 12 to move outward from the connecting frame 7. At the same time, the rack 13 drives the gear 11 to rotate. The rotation of the gear 11 synchronously drives the crossbar 10 to rotate around the pivot, causing the non-pivot end of the crossbar 10 to move inward into the connecting frame 7, opening the opening. The operator presses the position of the clamping block 9 and pulls the connecting frame 7 backward, allowing the groove to be removed from inside the connecting frame 7.
