[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1-5 This utility model provides an auxiliary nozzle unblocking device for an air-jet loom, including a conical nozzle 1, a filter box 2 on one side of the conical nozzle 1, a threaded connecting pipe 3 on one side of the filter box 2, an arc-shaped clearance opening 4 on the threaded connecting pipe 3, an arc-shaped plate 5 fixedly connected to the arc-shaped clearance opening 4 by bolts, a detachable ring 7 inside the filter box 2, a filter screen 14 welded inside the ring 7, a rotating shaft 15 rotatably connected to the filter screen 14, an impeller 16 at one end of the rotating shaft 15, and a plurality of brush plates 17 arranged in a circular array at the other end of the rotating shaft 15, with the brush plates 17 in contact with the filter screen 14, and a collection component 6 for collecting impurities at the bottom of the filter box 2. By placing the filter screen 14 inside the ring 7 and making the ring 7 detachable, the ring 7 can be removed after the arc-shaped plate 5 is disassembled, thus facilitating the cleaning of impurities that are difficult to clean by the brush plates 17 due to strong adhesion on the filter screen 14. The structure is simple and convenient for operators to operate.

[0024] In this utility model, the collection component 6 includes a connecting pipe 10, which is welded to the bottom of the filter box 2. A collection box 11 is slidably connected to the outer circumference of the connecting pipe 10, and a quick-release component is provided between the connecting pipe 10 and the collection box 11. A drop-out opening 12 is provided at the bottom of the inner circumference of the filter box 2, and the drop-out opening 12 is semi-circular. With the collection component 6, when the brush plate 17 cleans the impurities on the filter screen 14, the impurities cleaned off can fall into the collection box 11 through the drop-out opening 12, making it convenient to clean them.

[0025] To facilitate quick disassembly of the collection box 11, the quick-release assembly includes multiple limiting grooves 21, all of which are formed through the outer circumference of the collection box 11. The outer circumference of the connecting pipe 10 is provided with multiple circularly arrayed slots 19. Each limiting groove 21 contains a ball bearing 18, which is embedded in its corresponding slot 19. A slip ring 22 is slidably connected to the outer circumference of the collection box 11, and the inner circumference of the slip ring 22 contacts the ball bearings 18. Through the ball bearings 18 and the slots 19, the inner wall of the slip ring 22 is compressed when it is moved upwards. The ball 18 slides inward along the limiting groove 21, so that the ball 18 is inserted into the slot 19, and the collection box 11 can be installed on the connecting pipe 10. The structure is simple and easy to operate. Both ends of the limiting groove 21 are set to an inwardly concave arc shape, and the length of the limiting groove 21 is less than the diameter of the ball 18. By setting the two ends of the limiting groove 21 to have an inwardly concave arc shape, the ball 18 can be prevented from slipping out of the limiting groove 21. And by setting the length of the limiting groove 21 to be less than the diameter of the ball 18, it can be embedded into the slot 19 when the slip ring 22 squeezes the ball 18.

[0026] To facilitate the positioning and installation of the ring 7, two symmetrical positioning grooves 9 are provided on the arc-shaped inner wall of the arc plate 5. Two symmetrical positioning blocks 8 are welded to the top of the outer circumference of the ring 7, and the positioning blocks 8 are embedded in the corresponding positioning grooves 9. The positioning blocks 8 and positioning grooves 9 can be used to position the ring 7 after it is installed in the filter box 2, preventing the ring 7 from rotating during operation and thus affecting the cleaning effect on the filter screen 14. Two limiting rings 13 are welded to the inner circumference of the filter box 2, and the opposite sides of the two limiting rings 13 contact the two sides of the ring 7. The limiting rings 13 can be used to directly install the ring 7 between the two limiting rings 13, which is convenient for installation. A spring 20 is welded to the bottom of the outer circumference of the collection box 11, and the top of the spring 20 is fixed to the bottom of the slip ring 22. The spring 20 can apply an upward elastic force to the slip ring 22 to prevent the slip ring 22 from sliding downward on its own, thus preventing it from squeezing the ball 18.

[0027] The use of this utility model involves the following steps:

[0028] S1: When it is necessary to clean the strongly adhesive impurities on the filter screen 14, first remove the bolts on the arc plate 5 to disassemble the arc plate 5, then move the arc plate 5 upward along the arc-shaped relief opening 4 to remove the arc plate 5, and then the ring 7 can be taken out from the filter box 2. The staff can then clean the strongly adhesive impurities on the filter screen 14.

[0029] S2: When it is necessary to process the impurities generated by the filter box 2, the slip ring 22 is slid down along the collection box 11. When the top of the slip ring 22 is lower than the limiting groove 21, the ball 18 slides outward along the limiting groove 21. The ball 18 disengages from the slot 19, and the collection box 11 can be moved down and removed to clean the impurities collected on its inner wall.

[0030] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
