Detailed Implementation

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0017] Example 1: As Figures 1-5 ,include: The housing 100 has a threaded tube 110 at its tail end. An air pipe is sleeved on the outer wall of the threaded tube 110, and a locking nut 120 is threadedly connected to the connection between the air pipe and the threaded tube 110. The combined jet regulating assembly includes a limiting ring 200, the inner wall of which is fixedly connected to a first regulating tube 210. The first regulating tube 210 is locked to the inner wall of the output end of the housing 100 by a first end cap 140. The end of the first regulating tube 210 is threadedly connected to a second end cap 230. The outer wall of the first regulating tube 210 is provided with a first air outlet regulating ring 220. The inner wall of the second end cap 230 is rotatably connected to a second regulating tube 240. The outer wall of the second regulating tube 240 is provided with a second air outlet regulating ring 241. The housing 100 is circular. The outer wall of the threaded tube 110 is provided with anti-slip texture, which is used to enhance the friction of the connection part of the threaded tube 110.

[0018] The specific application scenario of this embodiment is as follows: The housing 100 provides the installation and protection foundation for the entire jet nozzle structure. The threaded tube 110 at its tail is used to connect to the air pipe of the loom, realizing the input of high-pressure airflow. The anti-slip texture on the outer wall of the threaded tube 110 can enhance the friction with the air pipe connection, preventing the air pipe from loosening under the impact of high-pressure airflow. After the air pipe and the threaded tube 110 are connected, the air pipe and the threaded tube 110 can be firmly locked by tightening the locking sleeve 120 of the connection to prevent airflow leakage. In the combined jet adjustment assembly, the limiting ring 200 is fixed to the first adjustment tube 210. The outer wall serves as a limit to ensure the stable installation position of the first regulating tube 210. The first regulating tube 210 is locked to the inner wall of the output end of the housing 100 by the first end cap 140, achieving a reliable connection with the housing 100. The first air outlet regulating ring 220 on the outer wall of the first regulating tube 210 can initially adjust the airflow output state. The second end cap 230 is threadedly connected to the end of the first regulating tube 210, providing an installation base for the second regulating tube 240. The second air outlet regulating ring 241 on the outer wall of the second regulating tube 240 further cooperates to adjust the airflow and adapt to different weft yarn traction requirements.

[0019] Example 2: Figures 3-5 The inner wall of the output end of the housing 100 is provided with a first blocking ring 130. The outer wall of the tail of the first adjusting tube 210 is slidably connected to the inner wall of the first blocking ring 130 in a sealing manner. The outer wall of the first adjusting tube 210 is threadedly connected to the inner wall of the first end cover 140, which is used to adjust the extension and retraction of the first adjusting tube 210 within the inner wall of the first blocking ring 130. The tail of the first adjusting tube 210 is a sealed structure. Three sets of first vent adjusting rings 220 are provided. The diameter of the three sets of first vent adjusting rings 220 increases sequentially from the inside to the outside. Position ring 200 is located inside the first end cap 140. The second adjusting tube 240 is threadedly connected to the inner wall of the second end cap 230. The second blocking ring 231 is fixedly connected to the inner wall of the second end cap 230. The second vent adjusting ring 241 is slidably connected to the inner wall of the second blocking ring 231. The end of the second adjusting tube 240 is a sealed structure. Three sets of second vent adjusting rings 241 are provided. The diameter of the three sets of second vent adjusting rings 241 increases sequentially from the inside to the outside. The output end of the second adjusting tube 240 is provided with a nozzle.

[0020] The specific application scenario of this embodiment is as follows: The first blocking ring 130 on the inner wall of the output end of the housing 100 is sealed and slidably connected with the outer wall of the tail of the first regulating pipe 210, which ensures that the first regulating pipe 210 can be flexibly extended and retracted, while preventing airflow leakage from the gap between the two. By rotating the first regulating pipe 210, the amount of extension and retraction of the first regulating pipe 210 on the inner wall of the first blocking ring 130 can be precisely adjusted by utilizing the threaded engagement between its outer wall and the inner wall of the first end cap 140, thereby changing the position of the first air outlet regulating ring 220 within the housing 100 and realizing the adjustment of the airflow output range. The sealing structure at the tail of the first regulating pipe 210 prevents airflow leakage from the tail of the pipe. The three sets of orifice diameters increase sequentially from the inside to the outside of the first air outlet. The orifice adjustment ring 220 allows for selection of air outlets with different orifice diameters to adjust the airflow intensity. The second adjustment tube 240 is threadedly connected to the inner wall of the second end cap 230. Rotating the second adjustment tube 240 changes its position. The second blocking ring 231 cooperates with the second air outlet adjustment ring 241 to ensure airflow sealing. The sealing structure at the end of the second adjustment tube 240 prevents airflow leakage. The three sets of second air outlet adjustment rings 241 with increasing orifice diameters cooperate with the first air outlet adjustment ring 220 to achieve fine airflow adjustment. Finally, the adjusted airflow is stably ejected through the nozzle at the output end of the second adjustment tube 240 to pull the weft yarn. This is suitable for weaving scenarios with high airflow precision requirements and diverse weft yarn materials.

[0021] The working principle of this utility model is as follows: When used by those skilled in the art, the housing 100 serves as the basic carrier, the tail threaded tube 110 is sleeved with the air pipe, and is locked by the locking nut 120 and the connection stability is enhanced by the anti-slip texture to ensure stable input of high-pressure airflow. In the combined jet regulating assembly, the first regulating tube 210 is connected to the output end of the housing 100 through the first end cap 140, and the first blocking ring 130 ensures its sealed sliding. Rotating the first regulating tube 210 can adjust the extension and retraction amount, and the airflow can be initially regulated in conjunction with the first air outlet regulating ring 220 with different orifice diameters. The second regulating pipe 240 is connected to the first regulating pipe 210 through the second end cap 230. The second blocking ring 231 ensures its sealed sliding. The second regulating pipe 240 is rotated to adjust its position. Combined with the second air outlet regulating ring 241 with different apertures, the airflow is further finely adjusted. Finally, the high-pressure airflow after two-stage adjustment is ejected from the nozzle at the output end of the second regulating pipe 240, stably pulling the weft yarn through the warp yarn opening to complete the weaving operation. The entire structure achieves precise control and stable delivery of airflow through multi-stage adjustment and sealing design, adapting to different weaving needs.

[0022] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
