[0034] Reference Figure 2 and Figure 3, a plurality of sleeves 11 are sleeved on the feed roller 1, and the yarn roll to be dyed is installed on the sleeve 11 to position the yarn roll. A bracket 81 is provided between the feed roller 1 and the first guide roller 5, and a plurality of yarn guides 8 corresponding to the sleeves 11 are rotatably connected to the bracket 81, and the axial direction of the yarn guide 8 is perpendicular to the axial direction of the feed roller 1. The yarn guide 8 includes a rotating column that fits the yarn and baffles at the upper and lower ends of the rotating column. The lowermost end of the first guide roller 5 is located between the two baffles of the yarn guide 8. At the same time, when the yarn wound on the yarn roll bypasses the yarn guide 8 and moves along the horizontal tangent direction of the yarn roll, the yarn is located between the two baffles of the yarn guide 8 in the vertical direction. In order for the yarn to move along the yarn guide 8, the sleeve 11 is located on one side of the yarn guide 8, so that the yarn roll sleeved on the sleeve 11 is tilted to bypass the yarn guide 8 away from the side of the sleeve 11.

[0035] Reference Figure 3 , the yarn passes through the yarn guide 8 and extends upward from the bottom of the first guide roller 5 along the side wall of the first guide roller 5, and then passes over the top of the tensioning roller 2. By adjusting the height of the tensioning roller 2, the tensioning roller 2 is brought into contact with the yarn to increase the tension of the yarn. The two ends of the tensioning roller 2 are rotatably connected with lifting blocks 21, and a tensioning frame 22 is provided between the feed roller 1 and the dyeing component 3.

The yarn coming out of the pretreatment unit 7 enters the first opening 314 at the entrance along the bottom of the first roller 315 at the entrance, and after dyeing, it moves toward the cooling box 32 from the first opening 314 at the outlet along the bottom of the first roller 315 at the outlet. The yarn enters the second opening 321 at the entrance along the bottom of the second roller 322 at the entrance, and after dyeing, it moves toward the next dyeing box 31 from the second opening 321 at the outlet along the bottom of the second roller 322 at the outlet. After passing through multiple dyeing boxes 31 and cooling boxes 32 in sequence, it moves toward the second guide roller 6, and is wound around the receiving roller 4 along the top of the second guide roller 6. The receiving roller 4 is made of carbon steel with a galvanized surface for rust and corrosion prevention.

The application of the ultrasonic oscillator 311 enhances the penetration ability of the dye solution, allowing the dyeing to penetrate deeper into the fiber, thereby improving the dyeing quality. The heating system 312 includes an electric heating tube 3121 and a temperature sensor 3122. The electric heating tube 3121 is arranged on the bottom surface inside the dyeing box 31, which can evenly heat the dye solution to ensure the consistency and stability of the dye solution temperature. The temperature sensor 3122 is fixed on the side wall inside the dyeing box 31, and can monitor the dye solution temperature in real time and feed it back to the control system, thereby achieving accurate temperature control, ensuring the stability of the temperature during the dyeing process, and improving the dyeing quality. The spray device 313 includes a spray pump 3131, a pipeline 3132 and a plurality of nozzles 3133. The spray pump 3131 is located on the bottom surface of the dyeing box 31. The nozzles 3133 are arranged one-to-one with the first opening 314 and are located above the first opening 314. The spray pump 3131 and the nozzles 3133 are connected through the pipeline 3132. The dye liquid in the dyeing box 31 is heated by the electric heating tube 3121, and the spray pump 3131 extracts the dye liquid and transports it to each nozzle 3133 through the pipeline 3132. The dye liquid is sprayed from the nozzle 3133 to dye the passing yarn.

[0041] Reference Figure 5 and Figure 6 Two baffles 316 are arranged in the dyeing box 31. The baffles 316 are located between the nozzle 3133 and the first opening 314 in the vertical direction. The nozzle 3133 is located between the two baffles 316 along the yarn movement direction. A slide plate 317 is slidably connected to the upper end surface of each baffle 316. A bidirectional lead screw 318 is rotatably connected to the dyeing box 31. The bidirectional lead screw 318 is threadedly connected to the slide plate 317. The two slide plates 317 slide in opposite directions. A driving motor 319 is arranged on the outer wall of the dyeing box 31 to drive the bidirectional lead screw 318 to rotate. The dye liquid sprays the yarn between the two baffles 316 through the nozzle 3133. The bidirectional lead screw 318 is driven to rotate by the driving motor 319, so that the position of the slide plate 317 can be accurately controlled, thereby controlling the length of the local dyeing of the yarn, thereby improving the flexibility and adaptability of the equipment.

[0042] Reference Figure 5A cooling water pipe 323 is provided in the cooling box 32, which can effectively reduce the temperature of the yarn after dyeing and prevent color fading caused by high temperature, while accelerating the cooling speed of the yarn, further shortening the production cycle. The cooling water pipe 323 is made of copper material, which has good thermal conductivity and corrosion resistance. An air cooling device can also be added to the cooling box 32. The air cooling device includes a fan and an air duct. The fan blows air into the air duct. The air duct is arranged along the path of the yarn to ensure that the air can directly contact the yarn and accelerate the cooling process. The air cooling device is combined with the water cooling device to more effectively reduce the temperature of the yarn and prevent color fading. The fan adopts a high-performance centrifugal fan with large air volume and low noise. The air duct is made of aluminum material, which has good thermal conductivity, is light and durable.

In the vertical direction, the lighting lamp 93 and the camera 92 are both located above the first opening 314 and are fixedly connected to the mounting frame 91, so that the yarn passes under the lighting lamp 93 and the camera 92. The specific installation positions of the camera 92 and the lighting lamp 93 can be adjusted according to actual production needs to obtain the best monitoring effect. The intelligent visual component 9 can monitor the color changes of the yarn in real time, dynamically adjust the dyeing parameters, reduce the scrap rate, ensure the color consistency of each batch of yarn, and thus improve the stability of the dyeing quality. The lighting lamp 93 is used to increase the brightness of the yarn, so that the camera 92 can accurately capture the color information of the yarn. The lighting lamp 93 adopts an LED light source with high brightness and long service life, ensuring that the camera 92 takes clear pictures. The camera 92 adopts a high-resolution industrial camera 92, which can capture subtle color changes of the yarn.

[0044] The implementation principle of a diversified yarn short-process dyeing processing equipment in an embodiment of the present application is as follows: the equipment feeds the yarn into the dyeing component 3 through the feed roller 1, the yarn guide 8 guides the yarn into the dyeing box 31, and the tensioning roller 2 maintains the appropriate tension of the yarn. The ultrasonic oscillator 311, the heating system 312 and the spray device 313 in each dyeing box 31 work together to ensure that the dye liquid is evenly distributed on the yarn, thereby improving the dyeing effect. The heating system 312 keeps the temperature of the dye liquid stable, and the cooling box 32 quickly cools the dyed yarn to prevent color fading. The intelligent visual system monitors the color changes of the yarn in real time, dynamically adjusts the dyeing parameters, ensures that the color of each batch of yarn is consistent, and improves the quality and stability of the dyeing.
