It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0029] Please see Figures 1 to 4 The present invention provides a spinneret for producing recycled polyester filament, comprising: a mounting platform 1 and an adjustment structure 3. A spinning plate 2 is mounted on the upper surface of the mounting platform 1 by means of the adjustment structure 3, and the upper surface of the mounting platform 1 is provided with the adjustment structure 3.

[0030] In the embodiments of this utility model, please refer to Figures 1 to 4The adjustment structure 3 includes several slide rails 301, which are fixedly connected to the mounting platform 1. Each pair of slide rails 301 forms a group. A movable plate 303 is slidably connected to the inner wall of each group of slide rails 301. Two positioning rods 304 are slidably connected to the surface of the movable plate 303. A connecting plate 305 is fixedly connected to the upper end of each positioning rod 304. A spring 306 is fitted onto the arc surface of each positioning rod 304. Both ends of the spring 306 are fixedly connected to the movable plate 303 and the connecting plate 305, respectively. Several positioning holes 307 are provided on the upper surface of the mounting platform 1. The inner wall of each positioning hole 307 is slidably connected to the positioning rod 304. An adjustment mechanism is rotatably connected to the upper surface of the movable plate 303. The section rod 308 and the adjusting rod 308 are threadedly connected to a horizontal plate 311. Limiting plates 312 are fixedly connected to both ends of the horizontal plate 311. Two round rods 313 are fixedly connected to the upper surface of the moving plate 303. The round surfaces of the round rods 313 are slidably connected to the horizontal plate 311 and the limiting plates 312. Several limiting grooves 314 are formed on the upper surface of the spinning plate 2. The inner walls of the limiting grooves 314 are slidably connected to the limiting plates 312. The position of the limiting plates 312 can be adjusted by operating the adjusting rod 308 and the connecting plate 305. The mounting platform 1 and the spinning plate 2 can be easily disassembled and assembled, facilitating user maintenance of the spinning plate 2. A sliding rod 302 is fixedly connected to the inner wall of the slide rail 301. The arc surface of the slide rod 302 is slidably connected to the moving plate 303. The slide rod 302 further limits the movement of the moving plate 303, making the moving plate 303 more stable when moving along the slide rail 301. The lower end of the positioning rod 304 is arc-shaped, which facilitates the positioning rod 304 sliding into the positioning hole 307. The upper end of the adjusting rod 308 is fixedly connected to the auxiliary plate 309. The arc surface of the auxiliary plate 309 has several circular holes. The inner wall of one of the circular holes is slidably connected to the handle 310. Operating the handle 310 drives the auxiliary plate 309 to rotate, and the auxiliary plate 309 drives the adjusting rod 308 to rotate, making it convenient for the user to rotate the adjusting rod 308. The limiting plate 31 A locking rod 315 is fixedly connected to the lower surface of the spinning plate 2. The arc surface of the locking rod 315 engages with the limiting groove 314. The locking rod 315 increases the limiting effect of the limiting plate 312 on the spinning plate 2, thereby improving stability. An anti-slip sleeve 316 is fixedly connected to the surface of the connecting plate 305. The surface of the anti-slip sleeve 316 has several anti-slip patterns. The anti-slip sleeve 316 increases the friction on the surface of the connecting plate 305, making it easier for the user to move the connecting plate 305. An auxiliary frame 317 is fixedly connected to the lower surface of the spinning plate 2. The outer surface of the auxiliary frame 317 is slidably connected to the mounting platform 1. The auxiliary frame 317 is docked with the mounting platform 1 to ensure the sealing between the mounting platform 1 and the extrusion hole on the spinning plate 2.

[0031] The working principle of the spinneret for producing recycled polyester filament provided by this utility model is as follows: By setting an auxiliary structure, first rotate the adjusting rod 308 on one side of the spinning plate 2. The adjusting rod 308 drives the horizontal plate 311 to move upward along the round rod 313 via the thread. The horizontal plate 311 drives the limiting plates 312 at both ends to move upward out of the limiting groove 314. Similarly, adjust the limiting plate 312 on the other side of the spinning plate 2 to fully move out of the limiting groove 314. Then pull the connecting plate 305 upward. The connecting plate 305 drives the two ends of the spinneret to move upward out of the limiting groove 314. The positioning rod 304 moves upward along the moving plate 303. During this process, the positioning rod 304 slides upward out of the positioning hole 307, and the spring 306 is in a stretched state, releasing the limit on the moving plate 303. Then, the moving plate 303 is moved along the slide rail 301 in a direction away from the spinning plate 2, so that the limiting plate 312 is away from the top of the spinning plate 2. After the moving plate 303 has moved a certain distance away from the spinning plate 2, the connecting plate 305 is released. The connecting plate 305 moves downward under the elastic force of the spring 306, connecting... The connecting plate 305 drives the positioning rod 304 to slide downwards into the corresponding positioning hole 307, fixing the position of the moving plate 303. Similarly, the limiting plate 312 on the other side of the operating platform 1 moves away from the spinning plate 2, fully releasing the limitation on the spinning plate 2. It can then be moved upwards away from the spinning plate 2 for maintenance and replacement. The sliding rod 302 further limits the moving plate 303, making it more stable when moving along the slide rail 301. The lower end of the positioning rod 304 is arc-shaped to facilitate positioning. Slide into the positioning hole 307, the operating lever 310 drives the auxiliary plate 309 to rotate, and the auxiliary plate 309 drives the adjusting rod 308 to rotate, making it convenient for the user to rotate the adjusting rod 308. The locking rod 315 increases the limiting effect of the limiting plate 312 on the spinning plate 2, improving stability. The anti-slip sleeve 316 increases the friction on the surface of the connecting plate 305, making it convenient for the user to move the connecting plate 305. The auxiliary frame 317 is used to dock with the mounting platform 1, ensuring the sealing between the mounting platform 1 and the extrusion hole on the spinning plate 2.
