[0025] Embodiment

[0026] Referring to Figures 1 - 3 , a low-tension dyeing device for ultra-fine polyester fabric, includes a dyeing tank 1, wherein: on both sides above the dyeing tank 1, a front frame plate 2 and a rear frame plate 3 are respectively fixedly installed, and between the front frame plate 2 and the rear frame plate 3, a winding shaft one 4, a winding shaft two 5, a winding shaft three 6 and a winding shaft four 7 are rotatably installed, and a tension control mechanism is fixedly installed between the front frame plate 2 and the rear frame plate 3; the tension control machine is between the winding shaft three 6 and the winding shaft four 7 to ensure the stability of the winding shaft one 4, the winding shaft two 5, the winding shaft three 6, the winding shaft four 7 and the tension control machine;

[0027] An electric heating mechanism is arranged in the dyeing tank 1, such as an electric heating wire heating system in the prior art, but not limited to only this one. Since the heating technology is a very mature technology in the prior art, there will be no excessive elaboration on it here;

[0028] It should be noted that the dyeing tank 1 can adopt an ultrasonic dyeing tank to improve the activity of the dye liquor in the dyeing tank 1 and better color the superfine polyester fabric.

[0029] The first winding shaft 4 and the second winding shaft 5 are below the third winding shaft 6 and the fourth winding shaft 7, and the third winding shaft 6 and the fourth winding shaft 7 are between the first winding shaft 4 and the second winding shaft 5. Through the settings of the first winding shaft 4, the second winding shaft 5, the third winding shaft 6 and the fourth winding shaft 7, during the process of dyeing the superfine polyester fabric, the flatness of the superfine polyester fabric can be ensured, the creases on the surface of the superfine polyester fabric can be reduced, and at the same time, loading and unloading can be carried out at both ends of the dyeing tank 1.

[0030] A first motor 8, a second motor 9, a third motor 10, a fourth motor 11 and a control box 16 are fixedly installed outside the front frame plate 2 to drive the corresponding first winding shaft 4 and second winding shaft 5, third winding shaft 6 and fourth winding shaft 7 to rotate, and the controller inside the control box 16 is communicatively electrically connected to the first motor 8, the second motor 9, the third motor 10, the fourth motor 11 and the tension control mechanism. The controller adopts existing technologies, such as the PLC controller in the existing technologies, so no more details will be elaborated here.

[0031] Slot holes 17 are respectively formed through the surfaces of the first winding shaft 4, the second winding shaft 5, the third winding shaft 6 and the fourth winding shaft 7, and concave cavities 18 are respectively formed in the slot holes 17 of the first winding shaft 4, the second winding shaft 5, the third winding shaft 6 and the fourth winding shaft 7 to provide a fixing space for one end of the superfine polyester fabric. Clamping mechanisms are respectively fixedly installed in the slot holes 17 of the first winding shaft 4, the second winding shaft 5, the third winding shaft 6 and the fourth winding shaft 7. The clamping mechanisms are clamped with the corresponding slot holes 17 to squeeze and fix one end of the superfine polyester fabric in the concave cavity 18.

[0032] The clamping mechanism includes a pressing plate 19, and a plurality of compression springs 20 are uniformly fixedly installed on one side surface of the pressing plate 19 to control the separation between the pressing plate 19 and the concave cavity 18. The pressing plate 19 is fixedly installed in each slot hole 17 through the compression springs 20. The pressing plate 19 is above the corresponding slot hole 17, and the pressing plate 19 is clamped in the corresponding slot hole 17 through the compression springs 20.

The cross beam 12 is fixedly installed above the front frame plate 2 and the rear frame plate 3, and the bottom surface of the cross beam 12 is fixedly connected to the electric push rod 13. A U-shaped frame 14 is fixedly installed at the output end of the electric push rod 13, and a roller 15 is rotatably installed inside the opening of the U-shaped frame 14, so as to control the roller 15 through the electric push rod 13 to adjust the depth of the ultra-fine polyester fabric entering the dyeing tank 1, enabling the ultra-fine polyester fabric to fully contact the dye liquor in the dyeing tank 1, thereby dyeing the ultra-fine polyester fabric. The U-shaped frame 14 is located between the front frame plate 2 and the rear frame plate 3. The electric push rod 13 is communicatively electrically connected to the controller.

[0034] In this embodiment, during use, two rolls of ultra-fine polyester fabric to be dyed are respectively wound around the winding shaft one 4 and the winding shaft two 5.

[0035] During winding, the pressing plate 19 is moved out of the corresponding concave cavity 18, and then one end of the ultra-fine polyester fabric is inserted into the slot 17 on the winding shaft one 4 and the winding shaft two 5 from below the pressing plate 19, and then the pressing plate 19 can be reset. The pressing plate 19 will press and fix one end of the ultra-fine polyester fabric in the concave cavity 18.

[0036] Then the upper winding can be carried out. After the upper winding is completed, the other end of the ultra-fine polyester fabric on the winding shaft one 4 is passed through below the roller 15 and fixed on the winding shaft four 7 in the above-mentioned manner.

[0037] After being fixed, the depth of the ultra-fine polyester fabric entering the dyeing tank 1 is adjusted by controlling the roller 15 through the electric push rod 13, enabling the ultra-fine polyester fabric to fully contact the dye liquor in the dyeing tank 1.

[0038] Then let the winding shaft one 4 unwind and the winding shaft four 7 wind up, so that the ultra-fine polyester fabric can be dyed. At the same time, according to the dyeing requirements, the ultra-fine polyester fabric can be wound and unwound and dyed in multiple cycles between the winding shaft one 4 and the winding shaft four 7.

[0039] After dyeing is completed, if the ultra-fine polyester fabric is wound on the winding shaft one 4, separate one end of the ultra-fine polyester fabric from the winding shaft four 7, and then it can be unwound onto an external winding roller through the winding shaft one 4. On the contrary, if it is on the winding shaft four 7, it can be unwound onto an external winding roller through the winding shaft four 7. After unwinding is completed, continue to wind the next roll of ultra-fine polyester fabric to be dyed.

[0040] During the unwinding process, the other end of the ultra-fine polyester fabric on the winding shaft two 5 can be passed through below the roller 15 and fixed on the winding shaft three 6 in the above-mentioned manner, and then dyed in the above-mentioned manner. In this way, the time generated during the loading and unloading process of the ultra-fine polyester fabric is saved, making the overall operation more efficient.

[0041] Any technical solution that uses the technical solution of the present utility model or is designed by those skilled in the art inspired by the technical solution of the present utility model and achieves the above technical effects shall fall within the protection scope of the present utility model.
