Description

Technical Field

[0001] This utility model belongs to the field of auxiliary nozzle calibration technology for jet looms, and specifically relates to an auxiliary nozzle angle calibration device for jet looms. Background Technology

[0002] In air-jet looms, weft insertion is achieved by injecting air jets from the main nozzle into the weft guide channel located in the warp yarn's shuttle, and by injecting air jets from the auxiliary nozzle to assist the weft yarn in passing through the shuttle. In air-jet loom weaving, weft stop is one of the important factors affecting the loom's efficiency. The non-standard positioning of the nozzle angle, height, etc., is an important cause of weft stop. If the nozzle angle or height is not standard, it will cause the airflow in the weft channel to be obstructed, resulting in weft insertion failure.

[0003] A search revealed a Chinese patent with publication number CN216585436U, which discloses an airflow jet adjustment device for an auxiliary nozzle of an air-jet loom. The device includes an adjustment body that engages with the auxiliary nozzle mechanism. The adjustment body has an engagement cavity, which allows for one-time adjustment of the airflow jet height and angle of the auxiliary nozzle, reducing the hassle of visual inspection during manual adjustment. However, the patent still has the following drawbacks: it is not easy to precisely adjust the angle of the auxiliary nozzle, and the nozzle angle may cause airflow obstruction in the weft yarn channel, leading to weft insertion failure.

[0021] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5This utility model provides an auxiliary nozzle angle calibration device for a jet loom, including a reed seat body 1 and a reed blade body 2 mounted on the surface of the reed seat body 1. Several toothed discs 5 are rotatably connected to the surface of the reed seat body 1. An auxiliary nozzle base 3 is disposed on the surface of the toothed discs 5, and an auxiliary nozzle body 4 is disposed inside the auxiliary nozzle base 3. Several gears 7 are rotatably connected to the surface of the reed seat body 1 via bearings. The gears 7 mesh with the toothed discs 5. A scale ring 9 is disposed around the gears 7, and a pointer 11 is fixedly connected to the surface of the gears 7. When the angle needs to be adjusted, the pointer 11 is used to calibrate the nozzle angle. Rotating gear 7 causes the auxiliary nozzle base 3 to rotate on the surface of the reed body 1 via the gear disk 5, thus changing the angle of the auxiliary nozzle body 4. To ensure accurate rotation, the angle of rotation of the auxiliary nozzle body 4 can be determined by observing the rotation angle of the pointer 11 while rotating gear 7 and by observing the angle at which the pointer 11 points to the surface of the scale ring 9. Since gear 7 and gear disk 5 are different sizes, the rotation angle of gear disk 5 needs to be calculated when rotating gear 7. The dimensions marked on the surface of scale ring 9 are the dimensions of gear disk 5 after rotation, which facilitates operation.

[0023] In this embodiment, a plurality of brackets 8 are uniformly fixedly connected along the axis on the surface of the reed base body 1. Each bracket 8 has a collar 12 fixedly connected inside. A positioning post 10 is inserted into the collar 12 and is rotatably connected to the collar 12. The positioning post 10 is fixedly connected to the gear 7. A plurality of positioning holes 13 are uniformly opened inside the positioning post 10. A locking block 15 is provided inside each positioning hole 13. The locking block 15 is slidably connected to the positioning post 10 through the positioning hole 13. A spring 14 is provided inside the positioning hole 13. The two ends of the spring 14 are fixedly connected to the locking block 15 and the positioning post 10, respectively. The inner wall of the collar 12 is provided with slots 16 inside the locking block 15. The locking block 15 is inserted into the slots 16. In order to position the auxiliary nozzle body 4 after determining the rotation angle, when the gear 7 needs to be rotated, force is applied to the positioning post 10. The positioning post 10 will drive the gear 7 to rotate inside the collar 12. When the positioning post 10 rotates, the locking block 15 will slide inside the positioning hole 13 due to the limitation of the collar 12. The spring 14 will make the locking block 15 stick tightly to the inner wall of the collar 12 due to the elastic potential energy. When the rotation stops at the appropriate angle, the spring 14 will push the locking block 15 into the slot 16 due to the elastic potential energy. The slot 16 limits the locking block 15, thereby limiting the gear 7 through the positioning post 10, preventing the gear 7 from rotating on its own, and realizing the real-time positioning of the angle of the auxiliary nozzle body 4.

[0024] In this embodiment, the reed base body 1 has several evenly spaced receiving grooves 17 along its axis inside. Each receiving groove 17 has a slider 18 inside, which is slidably connected to the reed base body 1 via the receiving groove 17. A positioning cylinder 19 is fixedly connected to the surface of the slider 18. The auxiliary nozzle base 3 has a positioning groove 20 inside, and the positioning cylinder 19 passes through the gear disc 5 and is inserted into the positioning groove 20. The auxiliary nozzle body 4 is located inside the positioning groove 20 and is inserted into the positioning cylinder 19. A positioning block 6 is fixedly connected to the surface of the gear disc 5 and is inserted into the auxiliary nozzle base 3 and slidably connected to it. A screw 21 is provided on the surface of the auxiliary nozzle base 3. One end of the screw 21 passes through the surface of the auxiliary nozzle base 3 and is threadedly connected to the positioning cylinder 19. A nut is threadedly connected to the outer end of the auxiliary nozzle base 3. The surface of the gear disc 5 has... A through groove is provided, and the positioning cylinder 19 is slidably connected to the toothed disc 5 through the through groove. When it is necessary to install the auxiliary nozzle body 4, first press the auxiliary nozzle base 3 towards the reed body 1 until the positioning cylinder 19 is inserted into the positioning groove 20. Then insert the auxiliary nozzle body 4 into the positioning cylinder 19. Then insert the screw 21 into the positioning cylinder 19 and rotate it. The screw 21 will move towards the auxiliary nozzle body 4 until the auxiliary nozzle body 4 is positioned by the screw 21. When it is necessary to adjust the height of the auxiliary nozzle body 4, move the screw 21 upward so that the positioning cylinder 19 moves upward in the receiving groove 17 through the slider 18. At the same time, the auxiliary nozzle base 3 will also slide on the surface of the positioning block 6 until the auxiliary nozzle body 4 moves to the appropriate height. Then put the screw 21 on the surface of the screw 21 and lock it. This realizes the adjustment and locking of the height of the auxiliary nozzle body 4.

[0025] The use of this utility model involves the following steps:

[0026] S1: When the angle needs to be adjusted, the gear 7 is rotated. The rotation of the gear 7 will drive the auxiliary nozzle base 3 to rotate on the surface of the reed body 1 through the toothed disc 5, thereby causing the angle of the auxiliary nozzle body 4 to change. If you want to rotate accurately, you can observe the rotation angle of the pointer 11 when rotating the gear 7. The angle of the pointer 11 pointing to the surface of the scale ring 9 determines the rotation angle of the auxiliary nozzle body 4. Since the gear 7 and the toothed disc 5 are different sizes, it is necessary to calculate the rotation angle of the toothed disc 5 when rotating the gear 7. The dimension marked on the surface of the scale ring 9 is the dimension after the toothed disc 5 has rotated, which is convenient for operation.

[0027] S2: In order to position the auxiliary nozzle body 4 after determining the rotation angle, when the gear 7 needs to be rotated, force is applied to the positioning post 10. The positioning post 10 will drive the gear 7 to rotate inside the collar 12. When the positioning post 10 rotates, the locking block 15 will slide inside the positioning hole 13 due to the limitation of the collar 12. The spring 14 will make the locking block 15 stick tightly to the inner wall of the collar 12 due to the elastic potential energy. When the rotation stops at the appropriate angle, the spring 14 will push the locking block 15 into the groove 16 due to the elastic potential energy. The groove 16 limits the locking block 15, thereby limiting the gear 7 through the positioning post 10, preventing the gear 7 from rotating on its own, and realizing the real-time positioning of the angle of the auxiliary nozzle body 4.

[0028] S3: When it is necessary to install the auxiliary nozzle body 4, first press the auxiliary nozzle base 3 towards the reed body 1 until the positioning cylinder 19 is inserted into the positioning groove 20. Then insert the auxiliary nozzle body 4 into the positioning cylinder 19. Then insert the screw 21 into the positioning cylinder 19 and rotate it. The screw 21 will move towards the auxiliary nozzle body 4 until the auxiliary nozzle body 4 is positioned by the screw 21. When it is necessary to adjust the height of the auxiliary nozzle body 4, move the screw 21 upward so that the positioning cylinder 19 moves upward in the receiving groove 17 through the slider 18. At the same time, the auxiliary nozzle base 3 will also slide on the surface of the positioning block 6 until the auxiliary nozzle body 4 moves to the appropriate height. Then put the screw 21 on the surface of the screw 21 and lock it. This realizes the adjustment and locking of the height of the auxiliary nozzle body 4.
