[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0028] Reference Figure 1-5 , which is an embodiment of the present invention, provides a weft insertion water pipe for a water jet loom, the weft insertion water pipe for a water jet loom comprising a pipe body 1, both ends of the pipe body 1 being detachably mounted with connecting ends 3, a cleaning assembly 2 being movably mounted on the pipe body 1, and a cleaning end of the cleaning assembly 2 being located inside the pipe body 1;

[0029] The cleaning assembly 2 includes a driving ring 21 sleeved on the tube body 1, and a cleaning body 25 located inside the tube body 1, and the driving ring 21 and the cleaning body 25 are magnetically adsorbed, and the cleaning ends on both sides of the cleaning body 25 are in conflict with the inner wall surface of the tube body 1. A limiting tube structure 23 is installed at both ends of the driving ring 21, and the tube body 1 passes through the inner hole of the limiting tube structure 23.

[0030] The driving ring 21 moves outside the tube body 1 and synchronously controls the cleaning body 25 located inside the tube body 1 to move to clean the inside of the tube body 1, thereby facilitating the cleaning of dirt and impurities in the tube body 1, ensuring the cleanliness of the inside of the tube body 1, and further ensuring the effect of weft insertion.

[0031] Grip rods 22 are detachably installed on both sides of the peripheral surface of the driving ring 21. Threaded holes are provided on both sides of the peripheral surface of the driving ring 21, and an external threaded rod threadedly connected to the threaded hole is welded on one end of the grip rod 22 close to the driving ring 21. The setting of the grip rod 22 provides a gripping point, which is more conducive to driving the driving ring 21 to move.

[0032] The cleaning body 25 includes a hollow tube 251, and an annular cleaning scraper 252 is fixed at both ends of the hollow tube 251. The annular cleaning scraper 252 cleans the inner wall surface of the tube body 1 when moving, removes the dirt and impurities left on the inner wall surface of the tube body 1, ensures the cleanliness of the inside of the tube body 1, avoids the smoothness of the water flow inside the tube body 1, and avoids blockage of the nozzle. The annular cleaning scraper 252 is installed on both sides for movement, and the main cleaning body 25 moves inside the tube body 1, and the inner wall surface of the tube body 1 can be cleaned, thereby improving the cleaning efficiency.

[0033] The annular cleaning scraper 252 is arranged in a trumpet shape, and the end of the annular cleaning scraper 252 away from the hollow tube 251 is in contact with the inner wall surface of the tube body 1. The trumpet-shaped annular cleaning scraper 252 is conducive to the annular cleaning scraper 252 fully contacting the inner wall surface of the tube body 1, thereby ensuring the cleaning effect of the annular cleaning scraper 252 on the inner wall surface of the tube body 1.

[0034] A magnetic ring 1 24 is installed on the inner wall of the driving ring 21, and a magnetic ring 254 is installed on the outer wall of the hollow tube 251. The opposing surfaces of the magnetic ring 1 24 and the magnetic ring 2 254 are magnetically attracted, and the opposing surfaces of the magnetic ring 1 24 and the magnetic ring 2 254 are inlaid with attractive magnetic blocks.

[0035] A second annular groove 253 is provided in the middle of the peripheral surface of the hollow tube 251 , and a second magnetic ring 254 is fixed inside the second annular groove 253 . A first annular groove 26 is provided in the middle of the inner wall surface of the driving ring 21 , and a first magnetic ring 24 is fixed inside the first annular groove 26 .

[0036] The tube limiting structure 23 includes a hard ring 232 sleeved on the tube body 1, and a circle of hard rod 231 is welded to one end face of the hard ring 232 close to the driving ring 21, and the end of the hard rod 231 close to the driving ring 21 is fixedly connected to the driving ring 21. The hard ring 232 and the hard rod 231 will first straighten the tube body 1 due to their hard material design, which is conducive to the smooth movement of the cleaning body 25 inside the tube body 1, so as to ensure the cleaning effect of the cleaning body 25 on the inner wall surface of the tube body 1.

[0037] Both ends of the tube body 1 are equipped with a hollow externally threaded tube 11, and the cleaning component 2 includes an internally threaded end cap 31 threadedly connected to the hollow externally threaded tube 11. The side of the internally threaded end cap 31 away from the tube body 1 is coaxially welded with a hollow externally threaded tube 32, and the internally threaded end cap 31 is connected to the interior of the hollow externally threaded tube 32. The inner hole diameter of the tube limiting structure 23 is smaller than the maximum outer diameter of the internally threaded end cap 31. The internally threaded end cap 31 is installed on both sides of the tube body 1, and the maximum diameter of the internally threaded end cap 31 is larger than the inner hole diameter of the tube limiting structure 23, which blocks the cleaning component 2 and prevents the cleaning component 2 from falling off the tube body 1. Moreover, when the tube body 1 needs to be disassembled, the cleaning component 2 can be disassembled from the tube body 1 by simply detaching the connecting end 3 at one end.

[0038] During use, the internally threaded end cap 31 is threadedly connected to the hollow externally threaded tube 11, and the hollow externally threaded tube 2 32 is detachably mounted on the tube body 1. The nozzle and the water inlet pipe are detachably connected to the tube body 1 by the arrangement of the hollow externally threaded tube 2 32.

[0039] When the driving ring 21 is sleeved on the tube body 1, the cleaning body 25 is located inside the tube body 1. Under the magnetic attraction of the first magnetic ring 24 and the second magnetic ring 254, when the driving ring 21 moves along the tube body 1, the cleaning body 25 located inside the tube body 1 is also driven to move. When the cleaning body 25 moves, the annular cleaning scraper 252 contacts the inner wall surface of the tube body 1, so the annular cleaning scraper 252 cleans the inner wall surface of the tube body 1 when it moves.

[0040] A hard ring 232 and a hard rod 231 are installed at both ends of the driving ring 21. Through the design of its hard material, the tube body 1 will be straightened first, which is conducive to the smooth movement of the cleaning body 25 inside the tube body 1 to ensure the cleaning effect of the cleaning body 25 on the inner wall of the tube body 1.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
