[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0020] like Figures 1 to 4 As shown, a yarn guide roller support device for air-jet spinning includes a guide roller body 1 and a first adjusting frame 2. The first adjusting frame 2 is installed at both the left and right ends of the guide roller body 1. A second adjusting frame 3 and a support frame 4 are horizontally connected and installed at the top of the first adjusting frame 2. The first adjusting frame 2 includes a support base 201, a damping rotary shaft 202, a shock absorber 203, and a limiting bearing 204. The damping rotary shaft 202 is installed at the bottom of the support base 201, and the shock absorber 203 is vertically connected to the bottom of the damping rotary shaft 202. A limiting bearing 204 is embedded in the middle of the shock absorber 203. The support base 201... Both the damping block 203 and the support base 201 are made of damping alloy material. The support base 201 has holes for bolt installation at the four opposite corners near the second adjusting frame 3. One end of the guide roller body 1 passes horizontally through the axis of the limiting bearing 204. The damping block 203 and the support base 201 are fixedly connected. The rotation characteristics of the damping rotary shaft 202 can be used to realize the flexible rotation of the guide roller body 1 in the horizontal direction to meet the yarn transmission requirements at different angles. At the same time, the damping block 203 can effectively absorb the vibration generated during spinning, reduce noise, and provide a stable transmission environment for the yarn.

[0021] like Figures 1 to 4 As shown, the second adjusting frame 3 includes a stabilizing frame 301, a docking seat 302, a damping slider 303, and positioning bolts 304. The docking seat 302 is installed on the side of the stabilizing frame 301 closest to the support frame 4, and the damping slider 303 is connected to the side of the docking seat 302 away from the stabilizing frame 301. Two sets of positioning bolts 304 are horizontally threaded onto both the upper and lower ends of the damping slider 303. An array of holes for connecting and installing the support frame 201 is formed on the bottom surface of the end of the stabilizing frame 301 closest to the support base 201. The stabilizing frame 301 and the docking seat 302... The four diagonal corners of the joint of the seat 302 are provided with holes for bolt installation. The docking seat 302 and the damping slider 303 are integrated into one structure. The stabilizer 301, docking seat 302 and damping slider 303 are all made of damping alloy material. The sliding characteristics of the damping slider 303 on the support guide rail 402 can be used to precisely adjust the lateral position of the guide roller body 1. The fastening effect of the positioning bolt 304 ensures the stability of the guide roller body 1 after adjustment, meeting the requirements of precise path control in the yarn transmission process.

[0022] like Figures 1 to 4As shown, the support frame 4 includes a main frame 401, a support rail 402, and a base 403. The support rail 402 is mounted on the surface of the main frame 401 near the second adjusting frame 3, and the base 403 is provided at both ends of the side of the main frame 401 away from the support rail 402. The support rail 402 and the damping slider 303 are connected to each other by a slotted embedded structure, and the main frame 401 and the base 403 are welded together. The end of the base 403 away from the main frame 401 has a hole structure for bolt installation. The main frame 401 and the base 403 are stably connected, providing a solid support foundation for the entire device. The bolt mounting holes on the base 403 facilitate the quick installation of the device onto textile machinery, ensuring the structural stability of the device during high-speed operation. At the same time, the slotted and embedded structure of the support guide rail 402 and the damping slider 303 ensures the smoothness and accuracy of the sliding of the second adjustment frame 3 on the support frame 4, further improving the accuracy of the lateral position adjustment of the guide roller body 1 and meeting the processing needs of yarns of different specifications.

[0023] In summary, as Figures 1 to 4 As shown, in use, the yarn guide roller support device for air-jet spinning first installs both ends of the guide roller body 1 into the limit bearings 204 of the first adjusting frame 2 to ensure that the guide roller body 1 can rotate smoothly and is in a stable position. Then, according to the specific model of the textile machinery and the yarn processing requirements, the angle of the damping rotary shaft 202 in the first adjusting frame 2 is adjusted so that the guide roller body 1 reaches the optimal working position. During this process, the shock absorber 203 can effectively absorb the vibration generated during spinning and ensure the stable operation of the guide roller body 1. Subsequently, the second adjusting frame 3 is connected to the support base 201 through the hole structure at the bottom of the stabilizing frame 301 and fixed with bolts to ensure a stable connection between the second adjusting frame 3 and the first adjusting frame 2. Then, according to the yarn transmission path, the position of the damping slider 303 on the support guide rail 402 is adjusted and fixed with the positioning bolt 304, thereby precisely controlling the lateral position of the guide roller body 1 and ensuring that the yarn maintains precise path control during transmission.

[0024] When installing the support frame 4, the main frame 401 is fixed to the textile machinery through the bolt mounting holes on the base 403 to ensure the stability of the entire device. The slotted embedded structure between the support guide rail 402 and the damping slider 303 allows the second adjustment frame 3 to slide smoothly on the support frame 4, further improving the flexibility and adaptability of the device. Once the entire device is installed, spinning operations can begin. During the spinning process, the guide roller support device, through its unique structural design, effectively reduces vibration and noise, providing a stable transmission environment for the yarn and ensuring the quality and efficiency of yarn processing. At the same time, its modular structure and flexible adjustment methods enable the device to adapt to different types of textile machinery and yarn processing requirements, greatly enhancing the device's market competitiveness and application value.
