The wall runs through the left end of the outer box 1. Multiple second guide rollers 10 are rotatably connected to the inner wall of the dyeing box 2. Fixed blocks 17 are fixedly connected to both the front and rear ends of the dyeing box 2. Sleeves 19 are fixedly connected to the bottom of each fixed block 17. Springs 20 are fixedly connected to the inner wall of each sleeve 19. Fixed rings 18 are fixedly connected to the other end of each spring 20. Pressure rollers 16 are rotatably connected to the inner wall of each fixed ring 18. The outer wall of each fixed ring 18 is slidably connected to the inner wall of the sleeve 19. The bottom ends of the two pressure rollers 16 are respectively set at the top ends of the left and right second guide rollers 10.

[0024] Specifically, the outer casing 1 serves as the main support and protective structure of the device. It has through holes 6 at both ends; the left through hole 6 is for polyester thread entry, and the right through hole 6 is for polyester thread exit, ensuring smooth and continuous polyester thread transport. A door 3 is hinged to the front of the outer casing 1, and an observation window 5 is fixedly connected to the inner wall of the door 3, allowing real-time monitoring of the internal dyeing and drying status. A handle 4 is fixedly connected to the lower front side of the door 3, facilitating quick opening and closing by operators for threading, maintenance, and cleaning. First guide rollers 9 are rotatably connected to the left and right sides of the inner wall at the rear of the outer casing 1. The left side... A guide roller 9 is used to smoothly guide the incoming polyester thread into the dyeing box 2. The first guide roller 9 on the right side is used to smoothly lead out the dyed polyester thread and send it into the drying area, realizing the stable turning of the polyester thread conveying direction. The bottom ends of the two pressure rollers 16 are respectively set at the top ends of the two second guide rollers 10 on the left and right. The left extrusion pair can squeeze out the air bubbles inside the polyester thread, allowing the dye to fully penetrate into the fiber gaps; the right extrusion pair can squeeze out excess dye, avoiding dye dripping, waste and pollution, while making the dye adhere more evenly. The pump body 8 provides conveying power, and dye can be replenished into the dyeing box 2 through the conveying pipe 7.

[0025] Reference Figure 2 and Figure 4 A stirring assembly is provided on the inner wall of the right end of the dyeing box 2. The stirring assembly includes a rotating shaft 12 rotatably connected to the inner wall of the right end of the dyeing box 2. Multiple stirring blades 13 are fixedly connected to the outer wall of the rotating shaft 12. A drive motor 14 is fixedly connected to the right end of the dyeing box 2. A support block 11 is fixedly connected to the right side of the inner wall of the bottom end of the dyeing box 2. The right end of the rotating shaft 12 is fixedly connected to the drive end of the drive motor 14. The left side of the outer wall of the rotating shaft 12 is rotatably connected to the inner wall of the support block 11. A drying assembly is provided on the inner wall of the right end of the outer box 1. The drying assembly includes an outer shell 15 fixedly connected to the inner wall of the right end of the outer box 1. An installation box 22 is installed on the inner wall of the outer shell 15. A heating coil 21 is provided on the inner wall of the installation box 22.

[0026] Specifically, the drive motor 14 drives the rotating shaft 12 to rotate. The support block 11 supports and limits the left end of the rotating shaft 12 to prevent it from shaking. The stirring blade 13 rotates synchronously with the rotating shaft 12 to continuously agitate the dye in the dyeing box 2, preventing dye pigment deposition and stratification. The heating coil 21 generates heat after being energized. The heat is evenly distributed through the mounting box 22 and the outer shell 15, drying the polyester thread passing above the outer shell 15. This quickly solidifies the dye on the surface of the polyester thread, preventing dye from sticking together during winding.

[0027] Working principle: In use, first pull handle 4 to open the door 3 and let the polyester thread to be dyed pass through the through hole 6 on the left side of the outer box 1. After passing around the first guide roller 9 on the left, it is introduced downward into the dyeing box 2. Then, the pressure roller 16 is lifted and separated from the second guide roller 10, so that the polyester thread passes between the pressure roller 16 and the second guide roller 10. Finally, it passes around the first guide roller 9 on the right and exits through the through hole 6 on the right side of the outer box 1. Then, close the door 3 and use an external drive device to pull the polyester thread to perform dyeing. During the dyeing process, the pressure roller 16 will be pressed tightly against the upper side of the corresponding second guide roller 10 under the elastic force of the spring 20 inside the sleeve 19, thereby applying pressure to the polyester thread, so that the polyester thread first enters the dyeing box 2. The yarn is squeezed to expel any air bubbles it may contain, allowing the dye to enter the polyester thread for dyeing. After dyeing, the pressure roller 16 on the right side and the second guide roller 10 perform a second squeeze to expel excess dye from the polyester thread, preventing excess dye from dripping and causing waste and pollution after the polyester thread is wound up. During the dyeing process, the drive motor 14 drives the rotating shaft 12 to rotate, causing the stirring blade 13 to agitate the dye inside the dyeing box 2, preventing pigment deposition inside the dye from affecting the dyeing effect. After dyeing, the polyester thread will pass over the top of the outer shell 15. At this time, the heating coil 21 set inside the mounting box 22 will generate heat to dry the polyester thread, which can further prevent the dye from dripping after the polyester thread is wound up.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
