[0002] The textile industry plays an important role in the social economy. At present, there are two main types of shuttleless looms: water jet looms and air jet looms. The weft insertion mechanism is an important component of the loom. The weft insertion mechanism uses various weft insertion methods to introduce the weft yarn into the shed so as to interweave with the warp yarn to form a fabric. The weft insertion mechanism of the water jet loom generates friction and traction on the weft yarn through the jet water flow, and introduces the weft yarn wrapped on the bobbin into the shed through the weft storage device.

[0003] In the prior art, the angle of the weft insertion head of the weft insertion mechanism cannot be freely adjusted, and its practicality is general; and the filter in the water tank is generally not equipped with a cleaning device, so that the filter is easily blocked after the weft insertion mechanism has worked for a period of time, resulting in a decrease in water pressure and a poor weft insertion effect.

DETAILED DESCRIPTION

[0022] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0023] See also Figures 1 to 6 The embodiment of the present application provides a weft insertion device for a water jet loom, including a receiving frame 1 and a water storage tank 2, a nozzle 3 is rotatably connected to the receiving frame 1, a hollow shaft 4 is installed on the receiving frame 1, a rotating block 5 is rotatably connected to the bottom of the hollow shaft 4, a connecting block 6 is hingedly connected to the bottom of the nozzle 3, a lifting plate 7 is installed at one end of the connecting block 6, a threaded rod 8 is installed on the lifting plate 7, and the threaded rod 8 is threadedly connected to the rotating block 5; a water outlet 9 is provided at the bottom of the receiving frame 1, and two baffles 10 are rotatably sealed and connected to the water outlet 9, and the baffles 10 are arranged oppositely and abut against each other after closing, two slide grooves 11 are provided in the water storage tank 2, and the two slide grooves 11 are arranged oppositely, and a sliding plate 12 is slidably connected in the slide groove 11, and a cleaning brush 13 is installed at one end of the sliding plate 12, and a spring 14 is installed in the slide groove 11, and one end of the spring 14 is connected to the sliding plate 12, and a filter screen 15 is installed in the water storage tank 2, and the cleaning brush 13 and the filter screen 15 are arranged in cooperation.

[0024] In this embodiment, water flow is sprayed from the nozzle 3 to perform weft insertion. When adjusting the angle of the nozzle 3, the rotating block 5 threadedly connected to the threaded rod 8 is rotated to make the threaded rod 8 rise or fall relative to the rotating block 5, so that the threaded rod 8 drives the connecting block 6 connected to the lifting plate 7 to move up and down. When the connecting block 6 moves, it is hinged with the nozzle 3 to complete the lifting or lowering of one end of the nozzle 3, and the other end of the nozzle 3 is rotatably connected to the receiving frame 1, thereby realizing the adjustment of the angle of the water flow sprayed from the nozzle 3. When the threaded rod 8 is rotated and raised by the rotating block 5, the upper part of the threaded rod 8 enters the hollow shaft 4. The water sprayed from the nozzle 3 is collected by the receiving frame 1 and gathered at the water outlet 9. When the water volume reaches a certain level, the baffles 10 sealed at two places are rotated to make the water flow fall. The impact force of the water flow makes the sliding plate 12 slide downward in the slide groove 11. When the water flow becomes smaller, the stretched spring 14 in the slide groove 11 drives the sliding plate 12 to slide upward, so that the sliding plate 12 moves up and down. The moving sliding plate 12 drives the cleaning brush 13 to clean the filter 15, thereby achieving the purpose of avoiding clogging of the filter.

[0025] In some embodiments, in order to facilitate the timing of opening the baffle 10 to allow the water to fall when the water jet loom is working, a linear drive device 16 is installed on the receiving frame 1. The linear drive device 16 can be an electric cylinder. A moving plate 17 is installed at the output end of the linear drive device 16. The moving plate 17 is provided with a transverse groove 18. A shaft 19 is installed on the baffle 10, and the shaft 19 slides in the transverse groove 18. When the linear drive device 16 is extended, the shaft 19 in the transverse groove 18 is driven to open the baffle 10 by the descending of the moving plate 17. The shaft 19 moves horizontally in the transverse groove 18 while descending with the moving plate 17, thereby achieving the purpose of opening it. In order to save the pulling force when closing the baffle 10, the shaft 19 is set at the end close to the abutment of the two baffles 10.

[0026] In some embodiments, in order to facilitate water spraying and angle adjustment of the nozzle 3, a water pump 20 is installed in the water tank 2, and a connecting pipe 21 is installed at the output end of the water pump 20. The connecting pipe 21 is a retractable hose, and the connecting pipe 21 is connected to the nozzle 3.

[0027] In some embodiments, in order to facilitate the preliminary filtration of the water flow after the nozzle 3 inserts the weft and to prevent the water flow from splashing and affecting the weft insertion effect, a second filter screen 22 is installed in the receiving frame 1, and a sponge pad 23 is installed on the second filter screen 22.

[0028] In some embodiments, in order to facilitate sealing after the two baffles 10 are closed, the ends of the baffles 10 that abut against each other are chamfered, thereby facilitating the opening and closing of the baffles 10 .

[0029] In some embodiments, in order to protect the linear drive device 16, a support column 24 is installed on the movable plate 17, and the support column 24 abuts against the outer wall of the receiving frame 1. The abutment between the support column 24 and the outer wall of the receiving frame 1 avoids uneven force on one end when the linear drive device 16 is working.

[0030] In some embodiments, in order to facilitate the rotational connection of the rotating block 5 at the bottom of the hollow shaft 4, an annular groove 25 is provided at the bottom of the hollow shaft 4, and a support block 26 is installed on the rotating block 5, and the support block 26 slides in the annular groove 25.
