[0031] In this embodiment, a mounting plate 3 is fixedly connected to one side of the top of the water tank 2, a water pipe 4 is arranged on the top of the water tank 2, and the bottom of the water pipe 4 passes through the water tank 2 and extends to the bottom of the water tank 2, a nozzle 401 is fixedly connected to the top of the water pipe 4, a water pump 6 and a flow control valve 5 are arranged on the water pipe 4, and the water pump 6 is fixedly connected to one side of the mounting plate 3.

[0032] Working principle: A weft insertion mechanism of a water jet loom. When in use, when the water in the water tank 2 is pressed into the nozzle 401 by the water pump 6 and the water jet is pulled by the weft, the water will be pulled by the water. Since the water has a certain kinetic energy, it will be sprayed on the shield 29, so that the shield 29 slides along the limit rod 28, and the first rack 11 is pulled by the connecting rod 24. At the same time, the spring 26 is compressed. When the first rack 11 is pulled, the second rack 13 is driven to move backward through the gear 10, so that the top of the U-shaped rod 15 slides in the inclined hole 17. Due to the restriction of the limit block 701, the lifting plate 16 rises with the lifting rod 18 and the insertion rod 20. When the plate 16 rises to the top of the limit block 701, as the second rack 13 continues to move, the lifting rod 18 slides along the sliding rod 23 with the insertion rod 20, so that the insertion rod 20 first rises and then moves toward the nozzle 401, so that the insertion rod 20 is inserted into the hole of the nozzle 401. When the spring 26 is reset, under the limit of the limit block 701, the lifting plate 16 first translates and then descends to achieve reset, so that the insertion rod 20 does not affect the nozzle 401 from spraying water again. In this way, after each water spraying, the insertion rod 20 clears the hole of the nozzle 401, making it difficult for the nozzle 401 to be blocked, thereby extending the service life of the nozzle 401 and reducing the number of maintenance times by the staff.
