The operation of the dyeing machine 200 will be described in detail below:

Referring to FIGS. 1 and 2, first, the cloth 1 is guided by the first guide roller 23, so that the cloth 1 can be moved to the immersion tank 221 via the upper opening 223 and immersed in the dyeing agent 222. Then, by the guiding of the second guiding roller 24, the cloth 1 can be moved backward in the dipping groove 221 in the front-rear direction X. By the lateral movement of the cloth 1 in the soaking tank 221, the time during which the cloth 1 is immersed in the dyeing agent 222 can be increased, so that the auxiliary dyeing agent 222 can easily penetrate into the fiber tissue of the cloth 1 to achieve uniform contamination on the cloth 1 The effect on it. Subsequently, the third guide roller 25 will lead the cloth 1 contaminated with the auxiliary dye 222 to the upper opening 223. When the cloth 1 moves backward and passes through the pressure roller 26, the pressure roller 26 presses out the excess dyeing agent 222 on the cloth surface of the cloth 1, so that the cloth 1 maintains a certain humidity. Then, the cloth 1 is guided to the transfer device 3 by the fourth guide roller 27.

Thereafter, the cloth 1 is moved between the outer surface 372 of the blanket 37 and the transfer carrier tape 330 via the guiding of the introduction roller 31. Since the pressure roller 351 of each pressurizing module 35 presses the blanket belt 37 to press the cloth 1, the cloth 1 is pressed into contact with the transfer carrier tape 330 to be in close contact with the heat transfer roller 32, thereby performing thermal transfer. The rotation of the roller 32 in the first rotational direction R1 simultaneously drives the transfer carrier tape 330, the cloth 1 and the carpet belt 37 to rotate. The cloth 1 is pressed into contact with the transfer carrier tape 330 by the pressurization of the pressure roller 351 of each pressurizing module 35, and the transfer carrier tape 330 is heated by the heat transfer roller 32, so that the heat transfer roller 32 is heated. The dye on the transfer carrier 330 can be transferred to the cloth 1 by thermal transfer. Since the cloth 1 has been uniformly contaminated with the dyeing agent 222 in advance, the dye on the transfer carrier tape 330 can be chemically reacted with the dyeing agent 222 on the cloth 1, so that the dye can be more quickly and uniformly Dyeing and fixing on the cloth 1.

When the thermal transfer roller 32 drives the transfer carrier tape 330, the cloth 1 and the blanket 37 to rotate to the guide roller 36 located above the thermal transfer roller 32, the transferred transfer carrier 330 is separated from the cloth 1 and is The take-up roll 34 is wound up. The blanket belt 37 moves rearward with the transfer cloth 1 around the guide roller 36 above the heat transfer roller 32. The transferred cloth 1 is separated from the carpet tape 37 and the transfer device 3 is led out by the take-up roller 38. The blanket 37 will then move downwardly and through the spray head 391 of the cleaning mechanism 39, which sprays water on the outer surface 372 of the blanket 37 to clean the flux 222 remaining on the outer surface 372. Next, the blanket 37 will pass through the brush roller 392, causing the brush roller 392 to scrub the outer surface 372. Subsequently, the blanket 37 will pass through the doctor blade 393, causing the blade 393 to scrape the water remaining on the surface 372. Finally, the blanket 37 will pass through the blow member 401 of the drying mechanism 40, and the blow member 401 blows the compressed hot air in the form of an air knife to the outer surface 372 to quickly dry the outer surface 372. Thereby, the carpet belt 37 can be continuously rotated and used.

In summary, the dyeing machine 200 of the present embodiment is designed by the liquid storage tank 22 of the pre-processing device 2, so that the cloth 1 can be pre-soaked in the auxiliary dye 222 and the auxiliary dye 222 can be uniformly contaminated on the cloth 1. . Thereby, in the subsequent thermal transfer process, the dye on the transfer carrier tape 330 can generate a chemical reaction of dyeing with the dyeing agent 222 on the cloth 1, so that the dye can be dyed more quickly and uniformly. On the cloth 1. Therefore, the type of the cloth 1 of the dyeing machine 200 may be a fabric containing polyester fiber, a nylon cloth, a cotton cloth, or the like, so that the application range can be effectively improved, and the object of the present invention can be achieved.
