In this embodiment, two first mounting plates 112 and two second mounting plates 113 are arranged on the dyeing tank 110, and the first mounting plates 112 and the second mounting plates 113 are spaced apart on the side wall of the dyeing tank 110 along the conveying direction of the fabric. On the top, two first mounting plates 112 are symmetrically distributed on both sides of the bleaching and dyeing tank 110, and two second mounting plates 113 are symmetrically distributed on both sides of the bleaching and dyeing tank 110. Two cloth-feeding rollers 114 are rotatably arranged between the two first mounting plates 112. The woven cloth passes through between the two cloth-feeding rollers 114 and enters the bleaching and dyeing tank 110 for bleaching and dyeing. Two cloth-discharging squeezing rollers 120 are rotatably arranged between the two second mounting plates 113. The length direction of the cloth-discharging squeezing rollers 120 is perpendicular to the transportation direction of the cloth. The cloth passes through between the two cloth-discharging squeezing rollers 120 and exits the bleaching and dyeing tank 110 to be discharged.

[0033] refer to Figure 1 , Figure 3 In order to squeeze out as much excess bleaching and dyeing liquid as possible from the fabric, the two cloth-out squeezing rollers 120 are radially close to each other along the cloth-out squeezing rollers 120, and sliders 121 are provided at both ends of the cloth-out squeezing rollers 120. An adjusting groove 122 for the slider 121 to slide radially along the cloth-out squeezing rollers 120 is provided on the bleaching and dyeing tank 110, and a driving member 123 is provided in the adjusting groove 122 to drive the two cloth-out squeezing rollers 120 to approach each other. In this embodiment, the two adjusting grooves 122 are respectively provided on the two second mounting plates 113, and the driving member 123 includes a driving spring 124 and an adjusting spring 125, one end of the driving spring 124 is connected to the slider 121, and the other end of the driving spring 124 is connected to the slider 121. One end is connected to the groove wall of the adjusting groove 122, one end of the adjusting spring 125 is connected to the side wall of the slider 121 away from the driving spring 124, and the other end is connected to the groove wall on the opposite side of the adjusting groove 122. The spring coefficient of the driving spring 124 is much larger than the spring coefficient of the adjusting spring 125. The two driving springs 124 are respectively located at the opposite side walls of the two sliders 121, and the two adjusting springs 125 are respectively located at the opposite side walls of the two sliders 121. The two driving springs 124 can overcome the spring resistance of the adjusting springs 125 to make the two cloth-out squeezing rollers 120 approach each other. The setting of the adjusting spring 125 provides elastic space for the sliding of the slider 121 in the adjusting groove 122.

[0034] refer to Figure 1In order to further reduce the probability of the bleaching and dyeing liquid squeezed out from the cloth-out squeezing roller 120 dripping onto the ground and to make the bleaching and dyeing tank 110 receive as much bleaching and dyeing liquid as possible, a blocking member 130 for receiving the bleaching and dyeing liquid dripping from the two cloth-out squeezing rollers 120 is obliquely arranged on one side wall of the bleaching and dyeing tank 110, and one end of the blocking member 130 is connected with the bleaching and dyeing tank 110.
