Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] See also Figure 1-5 , the utility model provides an embodiment: an angle-adjustable nozzle assembly for an air jet loom, comprising a base 1 and a nozzle body, the nozzle body being a nozzle for an air jet loom, the nozzle body comprising a ventilation pipe 2 and a nozzle head 3, an adjusting hole 301 being provided inside the nozzle head 3, an adjusting arc plate 8 being fitted on the inner side of the nozzle head 3, the adjusting arc plate 8 being in contact with the nozzle head 3 and being able to prevent air from flowing out of the gap between the adjusting arc plate 8 and the nozzle head 3 to a certain extent, an air jet port 801 being provided on the inside of the adjusting arc plate 8, a transmission plate 9 being fixedly mounted on one side of the adjusting arc plate 8, a transmission shaft 10 being fixedly mounted on the lower side of the transmission plate 9, a transmission cover 6 being fixedly mounted on the front end of the base 1, and a transmission cover 6 being fixed on one side A side box 5 is installed, and a drive shaft 13 is rotatably installed inside the transmission cover 6. The lower end of the transmission shaft 10 passes through the interior of the nozzle 3 and extends to the interior of the transmission cover 6. A gear transmission mechanism 1 is arranged between the transmission shaft 10 and the drive shaft 13. A connecting shaft 15 is rotatably installed inside the side box 5, and the connecting shaft 15 is fixedly connected to the drive shaft 13. A dial 19 is provided above the side box 5, and angle scale lines are provided on the upper end surface of the dial 19. A pointer 20 is provided above the dial 19, and a vertical shaft 18 is fixedly installed below one side of the pointer 20. The lower end of the vertical shaft 18 passes through the dial 19 and extends to the interior of the side box 5. A gear transmission mechanism 2 is arranged between the vertical shaft 18 and the connecting shaft 15.

[0025] During use, by driving the driving shaft 13 to rotate, the transmission shaft 10 is rotated through gear transmission, and the transmission plate 9 is used to rotate the adjustment arc plate 8 back and forth on the inner side of the nozzle 3, thereby changing the orientation angle of the air jet port 801, thereby realizing the adjustment capability of the air jet loom nozzle. At the same time, when the driving shaft 13 rotates, the connecting shaft 15 is driven to rotate, and the vertical shaft 18 is driven to rotate through gear transmission, so that the direction of the pointer 20 changes. Then, by checking the direction of the angle scale line of the pointer 20 on the dial 19, the adjustment angle can be known, which is beneficial to the accuracy of the angle adjustment of the nozzle assembly for the air jet loom.

[0026] Furthermore, a ring block 22 is fixedly installed on the outer side of the connecting shaft 15, and the outer surface of the ring block 22 is roughened. A pressure frame 23 is provided on the outer side of the ring block 22, and a friction block 26 is fixedly installed on the upper part of the pressure frame 23.

[0029] Furthermore, a fixed vertical plate 4 is fixedly installed on the front end of the base 1 along one side of the transmission cover 6, and a power cover 7 is fixedly installed on one side of the fixed vertical plate 4, which can protect the motor 14. A motor 14 is provided inside the power cover 7. The motor 14 is a servo motor. The motor 14 is fixedly connected to the fixed vertical plate 4, and the output end of the motor 14 is fixedly connected to the drive shaft 13, so that by starting the motor 14, the connecting shaft 15 can be driven to rotate, which is beneficial to the automatic adjustment of the nozzle angle.

[0030] Furthermore, the gear transmission mechanism includes a driven gear 11 and a driving gear 12, and the driven gear 11 is meshed with the driving gear 12. The driven gear 11 is fixedly installed below the transmission shaft 10, and the driving gear 12 is fixedly installed on the outside of the driving shaft 13, so that through the meshing transmission of the driven gear 11 and the driving gear 12, the transmission shaft 10 can be driven to rotate when the driving shaft 13 rotates, which is conducive to adjusting the nozzle angle.

[0031] Furthermore, the gear transmission mechanism 2 includes a driving gear 2 16 and a driven gear 2 17. The driving gear 2 16 is fixedly mounted below the vertical shaft 18, and the driven gear 2 17 is fixedly mounted on the outside of the connecting shaft 15. Through the meshing transmission of the driving gear 2 16 and the driven gear 2 17, the vertical shaft 18 can be driven to rotate when the connecting shaft 15 is driven to rotate, which is conducive to checking the adjustment angle.

[0032] Working principle: During use, when the nozzle angle of the air jet loom needs to be adjusted, the driving shaft 13 is driven to rotate, and then the rotational power is transmitted to the transmission shaft 10 through the gear transmission mechanism 1. The transmission shaft 10 drives the transmission plate 9 and the adjustment arc plate 8 connected thereto to rotate inside the nozzle 3, which can adjust the orientation angle of the air jet 801 and realize the jet direction adjustment of the nozzle. At the same time, the rotation of the driving shaft 13 also drives the gear transmission mechanism 2 to work through the connecting shaft 15, so that the vertical shaft 18 and the pointer 20 rotate synchronously with the connecting shaft 15. The change in the indication of the pointer 20 on the dial 19 reflects the angle of the air jet adjustment, which is convenient for accurately adjusting the nozzle angle.
