[0018] The specific implementation method is:

[0019] The dyeing tank 1 is rectangular and has an open top. When in use, the prepared dye solution is injected into the dyeing tank 1. Cloth guide rollers 3 are symmetrically and rotatably installed at both ends of the top of the dyeing tank 1. The dyeing component 2 is located between the two cloth guide rollers 3. The dyeing component 2 can dye and squeeze the fabric. The dyeing component 2 also includes a stirring piece. A motor 6 is fixedly installed on one side wall of the dyeing tank 1. The output shaft of the motor 6 is fixedly connected to the stirring piece of the dyeing component 2 to drive the stirring piece to stir the dye solution in the dyeing tank 1, thereby avoiding the precipitation of the dye in the dye solution; a collecting tank 5 is fixed on the side wall at one end of the dyeing tank 1, and a reflux port 4 is opened on the side wall. The reflux port 4 is located at the inner bottom of the collecting tank 5, so that the collecting tank 5 collects the dye solution dripping on the dyed fabric and then flows into the dyeing tank 1 through the reflux port 4 for continued use, thereby reducing the consumption of the dye solution. Example

[0020] On the basis of Example 1, this embodiment further defines that the dyeing component 2 includes a roller 7, a stirring rod 8 and an extrusion piece 9, a mounting rod 10 is fixed at the middle position of the top of the dyeing tank 1, and the extrusion piece 9 is arranged on the mounting rod 10, and rollers 7 are symmetrically rotatably arranged on both sides of the extrusion piece 9 in the dyeing tank 1, and two stirring rods 8 are rotatably arranged in the dyeing tank 1, and the two stirring rods 8 are respectively located in the two rollers 7, and the output shaft of the motor 6 is fixedly connected to one end of one of the stirring rods 8; rollers 7 are symmetrically arranged on both sides of the extrusion piece 9, and the purpose is to perform multiple dyeing on the fabric to improve the dyeing effect of the fabric. After the initial dyeing, the fabric is squeezed by the extrusion piece 9, and the dye liquid in the fabric is squeezed out by the extrusion piece 9. At the same time, the morphology of the fibers in the fabric can be changed by extrusion, so that the fabric can absorb more dye liquid during the secondary dyeing, thereby achieving the purpose of improving the dyeing effect of the fabric.

[0021] The other parts of this embodiment are the same as those of the above-mentioned embodiment 2 and will not be described in detail. Example

[0022] On the basis of Example 2, this embodiment further defines that the extrusion member 9 includes an auxiliary roller 11, an extrusion roller 12, a mounting frame 13, a limit rod 14 and a spring 15. The auxiliary roller 11 is rotatably mounted on the inner wall of the dyeing tank 1, and the extrusion roller 12 is rotatably mounted on the mounting frame 13. The limit rods 14 are symmetrically fixed at both ends of the top of the mounting frame 13. The two limit rods 14 are slidably arranged on the mounting rod 10, and the two limit rods 14 are sleeved with springs 15; when not in use, the extrusion roller 12 and the auxiliary roller 11 are pressed against each other and the spring 15 is in a slightly compressed state, so that the extrusion roller 12 can generate a certain extrusion force on the auxiliary roller 11. When in use, the fabric passes between the extrusion roller 12 and the auxiliary roller 11 after the initial dyeing, and the extrusion roller 12 squeezes the fabric through the elastic force of the spring 15 after compression, thereby achieving the purpose of squeezing out the dye in the fabric and changing the fiber morphology in the fabric.

The through grooves 16 provided on the roller 7 enable the dye in the dye solution to fully contact with the fabric when the motor 6 drives the stirring rod 8 to rotate, so that the fabric can absorb the dye.

[0025] The other parts of this embodiment are the same as those of the above-mentioned embodiment 2 and will not be described in detail. Example

[0026] Based on Example 2, this embodiment further defines that a synchronous belt 17 is connected between the two stirring rods 8; the setting of the synchronous belt 17 enables one motor 6 to drive the rotation of multiple stirring rods 8 at the same time, thereby reducing the use of the motor 6 and improving the utilization rate of the motor 6.

[0027] The other parts of this embodiment are the same as those of the above-mentioned embodiment 2 and will not be described in detail.

[0028] The working principle of this utility model:

[0029] When in use, the operator first injects the prepared dye solution into the dyeing tank 1, the dye solution contains disperse dyes and dyeing auxiliary agents, and then the fabric first passes through the cloth guide roller 3 on the dyeing tank 1 away from the collecting tank 5 at one end, then passes through the first roller 7 and passes between the auxiliary roller 11 and the squeezing roller 12, then passes under the second roller 7 and then passes out of the dyeing tank 1 from above the dyeing roller at the other end of the dyeing tank 1; during the dyeing process, the motor 6 drives the stirring rod 8 to stir the dye solution in the dyeing tank 1 to avoid dye precipitation. The stirring rod 8 is located inside the roller 7, and cooperates with the through groove 16 opened on the roller 7 to enable the dye in the dye solution to fully contact with the fabric, so that the fabric can absorb the dye; the squeezing roller 12 squeezes the fabric after the initial dyeing, and the squeezed fabric is dyed for the second time, thereby improving the dyeing effect of the fabric.
