Detailed Implementation

[0024] Example 1:

[0025] Please see Figure 1-5A one-bath dyeing apparatus for fabrics includes a dyeing tank 1, a controller 31 on one side of the dyeing tank 1, and a heat preservation device 2 inside the dyeing tank 1. The heat preservation device 2 includes an electric heating tube 10 and a heat-conducting plate 11. The heat-conducting plate 11 is arranged inside the dyeing tank 1, dividing the dyeing tank 1 into an upper dyeing zone 13 and a lower heating zone 12. The electric heating tube 10 is arranged inside the heating zone 12 and is curved. The electric heating tube 10 is electrically connected to the controller 31. The dye liquor is placed in the heating zone 12, and the heat-conducting plate 11 is heated by the electric heating tube 10, which in turn heats the dye liquor, thereby keeping the dye liquor within a suitable temperature range and ensuring the dyeing efficiency. At the same time, a vent is opened on the side of the heating zone 12. The vent, together with a fan, can dissipate heat from the heating zone 12 and prevent the electric heating tube 10 from being damaged due to excessive temperature.

[0026] The dyeing tank 1 is equipped with a connecting device 3 for placing fabric. The connecting device 3 includes a fabric roller 14, a guide roller 15, a pressure roller 16, and a drive assembly 17. Two fabric rollers 14 are provided, rotatably mounted inside the dyeing tank 1. The drive assembly 17 includes a drive motor 24, pulleys 25, a transmission belt 26, and two rotating shafts 27. Two rotating shafts 27 are provided, passing through the dyeing tank 1 and fixedly connected to one end of the fabric rollers 14, allowing for rotatable engagement between the rotating shafts 27 and the dyeing tank 1. Two pulleys 25 are provided, each sleeved and fixed onto the rotating shaft 27. The transmission belt 26 is sleeved on the two pulleys 25. Machine 24 is installed on one side of dyeing pool 1. The output end of drive motor 24 is fixedly connected to one of the rotating shafts 27. Several guide rollers 15 are arranged between two fabric rollers 14 and are arranged in an alternating manner. A fixed frame 18 is provided on the top of dyeing pool 1. A guide rod 19 is passed through the fixed frame 18. A mounting frame 20 is installed on one end of the guide rod 19. Pressure roller 16 is rotatably arranged inside the mounting frame 20. A spring 21 is installed on the guide rod 19. The two ends of the spring 21 are in contact with the mounting frame 20 and the fixed frame 18 respectively. Any two fabric rollers 14, guide rollers 15 and pressure rollers 16 are parallel to each other.

[0027] By fixing both ends of the fabric to two fabric rollers 14, the fabric passes through guide roller 15 and pressure roller 16. The guide roller 15 increases the contact area of ​​the fabric with the dye liquor inside the dye bath 1, and the pressure roller 16 can prevent the fabric from being too tight or too loose. At the same time, the rotation of the two fabric rollers 14 can be achieved by the cooperation of drive motor 24, pulley 25 and transmission belt 26, thereby realizing the movement of the fabric. The moving fabric can ensure uniform dyeing.

[0028] A mixing cylinder 4 is provided on one side of the dyeing tank 1, and a centrifugal pump 5 is provided on the other side of the dyeing tank 1. The input end of the centrifugal pump 5 is connected to the dyeing tank 1, and the output end of the centrifugal pump 5 is connected to the mixing cylinder 4. A stirring device 6 is provided inside the mixing cylinder 4. The stirring device 6 includes a stirring motor 22 and a stirring rod 23. The stirring motor 22 is arranged at the bottom of the mixing cylinder 4, and the stirring rod 23 is arranged inside the mixing cylinder 4. The stirring rod 23 and the mixing cylinder 4 rotate in cooperation. The stirring rod 23 and the output end of the stirring motor 22 are fixedly connected. A return centrifugal pump 7 is provided at the top of the dyeing tank 1. The input end of the return centrifugal pump 7 is located inside the mixing cylinder 4, and the output end of the return centrifugal pump 7 is located inside the dyeing tank 1. A spray pipe 8 is provided inside the dyeing tank 1. The return centrifugal pump 7 is connected to the spray pipe 8, and a material inlet 9 is opened on the spray pipe 8. The centrifugal pump 5, the return centrifugal pump 7, and the stirring motor 22 are all electrically connected to the controller 31.

[0029] The combined action of the centrifugal pump 5 for material extraction and the centrifugal pump 7 for return ensures the flow of dye liquor within the dyeing tank 1. The flowing dye liquor effectively guarantees uniform dyeing. Meanwhile, the combined action of the stirring motor 22, the stirring rod 23, and the mixing cylinder 4 stirs the dye liquor inside, preventing sedimentation.

[0030] This application also includes a three-way connector 28 installed at the output end of the centrifugal pump 5, and connecting pipes 29 installed at the other two ends of the three-way connector 28. One of the connecting pipes 29 is located inside the mixing cylinder 4, and valves 30 are installed on the two connecting pipes 29 respectively. By opening different valves 30, the dye liquor can be transferred to the mixing cylinder 4 or directly discharged, which can facilitate discharge and meet different needs.

[0031] Working principle:

[0032] Before use, open valve 30 on the connecting pipe 29 connected to the mixing cylinder 4 and close another valve 30. Fix one end of the fabric to one of the fabric rollers 14. The fabric passes around several guide rollers 15 and pressure rollers 16. The other end of the fabric is fixed to another fabric roller 14, and the excess fabric is wrapped around one of the fabric rollers 14. Add the dye solution to the dyeing tank 1.

[0033] In use, the controller 31 controls the electric heating tube 10 to start, and the electric heating tube 10 heats the heat conduction plate 11. The heat conduction plate 11 heats the dye liquor inside the heating zone 12, so that the dye liquor is kept in a stable temperature range, thereby improving the dyeing efficiency. The controller 31 controls the drive motor 24 to rotate, and the drive motor 24 drives the fabric roller 14 to rotate. The fabric roller 14 makes the fabric move between the two fabric rollers 14, which facilitates the contact between the dye liquor and the fabric.

[0034] Simultaneously, controller 31 controls the start of the extraction centrifugal pump 5, which draws the dye liquor into the mixing cylinder 4. Controller 31 also controls the start of the stirring motor 22, which drives the stirring rod 23 to rotate. The stirring rod 23 then stirs and mixes the dye liquor inside the mixing cylinder 4. After stirring, the dye liquor enters the spray pipe 8 through the return centrifugal pump 7. The dye liquor is then sprayed out through the nozzle 9 on the spray pipe 8, thus dyeing the fabric. The cooperation between the extraction centrifugal pump 5 and the return centrifugal pump 7 allows the dye liquor to flow, ensuring uniform dyeing.

[0035] After dyeing is completed, by closing valve 30 on the connecting pipe 29 connected to the mixing cylinder 4 and opening another valve 30, the dyeing solution inside the dyeing tank 1 can be extracted and replaced by the centrifugal pump 5.
