[0002] Fabric padding dyeing is a dyeing technique carried out on fabrics, usually used for making complex patterns and color effects. This technique involves applying dyes or pigments to the entire fabric surface, rather than applying or soaking locally as in traditional dyeing. Fabric padding dyeing can be achieved by different methods, including spraying, brushing, printing or other application techniques.

[0003] Chinese Patent with the authorization announcement number CN218203438U discloses a supercritical fluid opposed jet dyeing device, which can perform simultaneous jet dyeing treatment on both sides of the fabric through bidirectionally arranged nozzles.

[0023] Embodiment 1

[0024] As Figures 1 - 3 shown, a dip dyeing device for polyester fabrics proposed by the present utility model includes a bottom plate 1, a spray dyeing assembly and a linkage mechanism. A dyeing box 2, an unwinding member and a winding member are arranged on the bottom plate 1. A guiding roller 3 located between the winding member and the unwinding member is rotatably arranged on the dyeing box 2. The spray dyeing assembly is arranged on the dyeing box 2 between two groups of guiding rollers 3, and includes a pump body 4, a U-shaped three-way pipe 5 communicated with the dyeing box 2 through the pump body 4, and a spray pipe 6 rotatably communicated with two horizontal sections of the U-shaped three-way pipe 5. The linkage mechanism is arranged on the bottom plate 1 and is used to cooperate with the winding member to drive the spray pipe 6 to rotate horizontally.

[0025] As Figure 1 shown, the winding member includes a vertical plate a 7, a motor 8 and a winding shaft 9. Two groups of vertical plates a 7 are arranged symmetrically at one end of the bottom plate 1. The winding shaft 9 is rotatably arranged between the two groups of vertical plates a 7. A motor 8 connected to the winding shaft 9 is installed outside the corresponding vertical plate a 7.

[0026] As Figure 2 shown, the unwinding member includes a vertical plate b 10 and an unwinding shaft 11. Two groups of vertical plates b 10 are arranged symmetrically at one end of the bottom plate 1 away from the vertical plate a 7. The unwinding shaft 11 is rotatably arranged between the two groups of vertical plates b 10.

[0027] As Figure 3 shown, both groups of spray pipes 6 are arranged in a T-shaped structure, and a plurality of groups of nozzles 12 arranged oppositely are linearly and equidistantly communicated on the horizontal sections thereof.

[0028] Among them, the fabric shuttles between the unwinding shaft 11, the winding shaft 9 and the guiding roller 3. The motor 8 drives the winding shaft 9 to rotate, so as to wind the fabric. During the winding process, the pump body 4 extracts the dye liquor in the dyeing box 2 into the U-shaped three-way pipe 5 and diverts it into the spray pipe 6, so as to spray and dye both sides of the fabric by using the nozzles 12.

[0029] Embodiment 2

[0030] As Figures 1 - 3 shown, based on the above embodiments, the present utility model provides a dip-dyeing device for polyester fabrics. In this embodiment, the specific components of the linkage mechanism and its driving method for the spraying component are further described in detail.

[0031] As Figure 2 and Figure 3 shown, the linkage mechanism includes a mounting plate 13, a linkage shaft 14, a main bevel gear 15, a driven bevel gear 16, a first transmission member, and a second transmission member. The mounting plate 13 is disposed on the bottom plate 1, and two groups of linkage shafts 14 are rotatably penetrated therethrough. One end of each of the two groups of linkage shafts 14 is connected to a main bevel gear 15. A driven bevel gear 16 is meshed with one side of the two groups of main bevel gears 15. The driven bevel gear 16 is disposed on the vertical section of the spray pipe 6. A first transmission member is disposed between one of the linkage shafts 14 and the winding shaft 9, and a second transmission member is disposed between the two groups of linkage shafts 14.

[0032] As Figure 2 shown, the first transmission member includes pulley a 17 and belt a 18. There are two groups of pulley a 17, which are respectively installed on the output shafts of the corresponding linkage shaft 14 and the winding shaft 9. Belt a 18 is connected for transmission between the two groups of pulley a 17. When the winding shaft 9 winds the fabric, the cooperation of pulley a 17 and belt a 18 drives one of the linkage shafts 14 to rotate.

[0033] As Figure 1 shown, the second transmission member includes pulley b 19 and belt b 20. There are two groups of pulley b 19, which are respectively installed on the two groups of linkage shafts 14. Belt b 20 is connected for transmission between the two groups of pulley b 19. When one of the linkage shafts 14 rotates, the cooperation of pulley b 19 and belt b 20 drives the other linkage shaft 14 to rotate synchronously.

[0034] In summary, when the present utility model is in use, the fabric is shuttled between the unwinding shaft 11, the winding shaft 9, and the guide shaft. The pump body 4 is started, and the pump body 4 extracts the dye liquor in the dyeing tank 2 into the U-shaped tee 5 for diversion into the spray pipe 6, so as to spray the two sides of the fabric by using the spray head 12. During the spraying process, the motor 8 drives the winding shaft 9 to rotate to wind the fabric from the unwinding shaft 11 onto the winding shaft 9. During the winding process, the cooperation of pulley a 17 and belt a 18 drives one of the linkage shafts 14 to rotate. One of the linkage shafts 14 drives the other linkage shaft 14 to rotate synchronously through the cooperation of pulley b 19 and belt b 20. When the two groups of linkage shafts 14 rotate synchronously, the main bevel gears 15 thereon are driven to rotate. The main bevel gear 15 drives the spray pipe 6 to rotate through meshing with the driven bevel gear 16, thereby expanding the spraying range of the spray head 12, improving the spraying uniformity and dyeing efficiency, and not requiring additional power expenditure cost, thus improving its practicability.

[0035] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited thereto, and various changes can be made without departing from the spirit of the present utility model within the scope of knowledge possessed by those skilled in the relevant technical field.
