A third conveying roller 26 is provided at the front end of the first leveling mechanism, and a fourth conveying roller 56 is provided at the front end of the second leveling mechanism. The third conveying roller 26 and the fourth conveying roller 56 both play the role of transitionally conveying polyester fabrics.

[0030] A first liquid inlet pipe 27 and a first liquid outlet pipe 28 are provided on one side of the bleaching tank 1, and a first valve 29 is provided on the first liquid inlet pipe 27 for controlling the entry of bleaching agent, and a second valve 30 is provided on the first liquid outlet pipe 28 for controlling the discharge of bleaching agent; a second liquid inlet pipe 57 and a second liquid outlet pipe 58 are provided on one side of the dyeing tank 2, and a third valve 59 is provided on the second liquid inlet pipe 57 for controlling the entry of dye, and a fourth valve 60 is provided on the second liquid outlet pipe 58 for controlling the discharge of dye.

[0031] Here’s how it works:

[0032] First, open the first valve 29 on the first liquid inlet pipe 27 and the third valve 59 on the second liquid inlet pipe 57, discharge a certain amount of bleach (usually hydrogen peroxide) and dye, close the first valve 29 and the third valve 59 (when the bleach or dye needs to be replaced, open the second valve 30 and the fourth valve 60 to discharge the bleach in the bleaching tank 1 and the dye in the dyeing tank 2, and then re-input new bleach and dye through the first liquid inlet pipe 27 and the second liquid inlet pipe 57), and turn on the first rotary motor 241 and the second rotary motor 541. Then, the polyester fabric 4 is transported into the bleaching tank 1 through the third conveying roller 26, and after the distance between the first upper fabric guide roller 16 and the first lower fabric guide roller 17 is adjusted by the first lifting assembly 18, the fabric 4 is transported between the first upper fabric guide roller 16 and the first lower fabric guide roller 17, and then transported to the first water filter mechanism through the first conveying roller 11.

[0033] When the polyester fabric 4 is conveyed between the first leveling mechanism and the first conveying roller 11, the bleaching agent will be sprayed by the first nozzle 13. When the fabric 4 is conveyed to the first water filtering mechanism, the first toggle block 23 can be manually pressed down, and the fabric 4 passes between the first upper fabric guide roller 16 and the first lower fabric guide roller 17, and then the first toggle block 23 is released. At this time, the first upper fabric guide roller 16 and the first lower fabric guide roller 17 will apply pressure to the fabric 4, which can squeeze out the excess bleaching agent in the fabric 4 and drop it back into the bleaching tank 1 through the first drainage plate 25.

[0034] After the fabric is bleached, it is then transferred into the dyeing tank 2 through the fourth conveying roller 56. Similarly, after the distance between the second upper fabric guide roller 46 and the second lower fabric guide roller 47 is adjusted by the second lifting assembly 48, the fabric 4 is conveyed between the second upper fabric guide roller 46 and the second lower fabric guide roller 47, and then conveyed to the second water filtering mechanism through the second conveying roller 41. After the fabric 4 is sprayed with dye by the second nozzle 43, the excess dye is squeezed out by the second water filtering mechanism, and then conveyed to the upper heating chamber 31 and the lower heating chamber 32 for drying treatment, so as to obtain the polyester fabric 4 after dyeing and brightening.

[0035] In the present application, the bleach is sprayed onto the surface of the polyester fabric 4 through the first circulation pipe 14, the first circulation pump 15 and the first nozzle 13, and then the dye is sprayed onto the surface of the polyester fabric 4 through the second circulation pipe 44, the second circulation pump 45 and the second nozzle 43 to dye and enhance the color; and the bleach and dye at the spraying point will fall back to the bottom of the bleaching tank 1 and the dyeing tank 2 for recycling, thereby reducing the waste of bleach and dye.

[0036] In the present application, the polyester fabric 4 is first flattened by a first flattening mechanism, and then the excess bleach in the fabric 4 is squeezed out by a first water filtering mechanism after bleaching, and then the fabric 4 is flattened by a second flattening mechanism for dyeing, and after coloring, the excess dye is squeezed out by a second water filtering mechanism, and finally a drying treatment is performed. In this process, bleaching and dyeing are performed after flattening, which avoids the phenomenon of uneven bleaching and dyeing, and improves the dyeing and brightening effect of the polyester fabric 4. The device has a high degree of mechanization and improves the dyeing efficiency.

[0037] The above content is a further detailed description of the technical solution provided in combination with the preferred implementation methods of this patent. It cannot be determined that the specific implementation of the utility model is limited to the above descriptions. For ordinary technicians in the technical field to which this patent belongs, without departing from the concept of this patent, they can also make several simple deductions or substitutions, which should be deemed to fall within the scope of protection of this patent.
