[0036] Combination Figure 1 to Figure 2 As shown, the utility model provides a pretreatment device 20 of a continuous pad dyeing system, comprising: a continuous pad dyeing system 10, which has a cloth feed end 110; a pretreatment device 20, which is arranged at the cloth feed end 110; the pretreatment device 20 comprises: a material trough 210, which is filled with a dye 211; a rotating roller 220, which is arranged in the material trough 210; the rotating roller 220 is completely immersed in the dye 211, or the rotating roller 220 is partially immersed in the dye 211; the cloth 30, which contacts the dye 211 in the material trough 210 under the action of the rotating roller 220, and is sent into the continuous pad dyeing system 10 through the cloth feed end 110.

[0037] Specifically, the present application sets a pretreatment device 20 in front of the cloth inlet end 110 of the continuous roller dyeing system 10 of the prior art. The pretreatment device 20 includes a material trough 210 and a rotating roller 220. The cloth 30 to be continuously roller dyed is contacted with a small amount of dye 211 under normal temperature and pressure environment for pre-infiltration. The pre-infiltrated cloth 30 then enters the continuous roller dyeing system 10 for continuous roller dyeing. Since the pretreatment device 20 performs dye 211 infiltration treatment on the cloth 30 at normal temperature and pressure, the cloth 30 can be wrinkle-free during subsequent continuous roller dyeing under high temperature and high pressure conditions.

[0038] In this embodiment, the pretreatment device 20 further includes a first steering roller 230 and a second steering roller 240, both of which are arranged above the material tank 210; the first steering roller 230 is arranged at the front end of the rotating roller 220, and is used to transfer the cloth 30 to the rotating roller 220; the second steering roller 240 is arranged at the rear end of the rotating roller 220, and is used to send the cloth 30 from the rotating roller 220 into the continuous pad dyeing system 10. Specifically, the undyed cloth 30 is turned and transferred to the rotating roller 220 under the action of the first steering roller 230, and then the rotating roller 220 makes the cloth 30 contact with the dye solution in the material tank 210 under the action of rotation to become the pre-dyed cloth 30, and then it is transferred to the continuous pad dyeing system 10 under the action of the second steering roller 240 for continuous pad dyeing.

[0039] In addition, since the first steering roller 230 and the second steering roller 240 are both arranged above the material trough 210, the staff can observe the condition of the cloth 30 on the second steering roller 240 to ensure that the pre-dyed cloth 30 is wrinkle-free before entering the continuous roller dyeing system 10.

[0040] In this embodiment, the pretreatment device 20 further includes a recovery tray 250 disposed below the second steering roller 240, and the recovery tray 250 is tilted downward from the rear to the front. During the process of the second steering roller 240 steering the pre-dyed fabric 30, the second steering roller 240 squeezes out the excess dye 211 in the pre-dyed fabric 30, and the excess dye 211 drips onto the recovery tray 250 after being squeezed out, and flows back into the material trough 210 along the tilted direction, thereby realizing recycling and preventing excessive dye 211 from entering the continuous pad dyeing system 10.

[0041] In this embodiment, the rotating roller 220 is a passive roller. The pretreatment device 20 of the present application is used in conjunction with the continuous pad dyeing system 10 , and the power provided by the continuous pad dyeing system 10 is used to rotate the rotating roller 220 .

[0042] In this embodiment, the continuous pad dyeing system 10 includes a dye tank 120, in which a dye 211 is contained; the pretreatment device 20 also includes a liquid replenishing pipe 260, one end of which is connected to the dye tank 120, and the other end of which is connected to the material tank 210. The present application installs a liquid replenishing pipe 260 between the dye tank 120 and the material tank 210 so that the excess dye in the dye tank 120 can be replenished into the material tank 210.

[0043] Furthermore, a drain pipe 130 is provided in the dye tank 120, and the drain pipe 130 has a liquid inlet end and a liquid discharge end, the liquid discharge end is connected to the liquid replenishment pipe 260, and the liquid inlet end is at a preset liquid level of the dye tank 120; the height of the preset liquid level is higher than the liquid level height of the dye 211 in the material tank 210. When the dye 211 in the dye tank 120 reaches the preset liquid level of the dye tank 120, the dye 211 will flow into the drain pipe 130 through the liquid inlet end, and then be input into the liquid replenishment pipe 260 through the liquid discharge end, and finally flow into the material tank 210, so as to replenish the dye 211 in the material tank 210. Moreover, the dye 211 in the dye tank 120 can be prevented from overflowing.

[0044] Furthermore, the material tank 210 is provided with a liquid level detection device for detecting the liquid level of the dye 211 in the material tank 210; the pretreatment device 20 also includes a control device and an indication device, and the control device is electrically connected to the liquid level detection device and the indication device, and is used to start the indication device when the dye 211 in the material tank 210 reaches a specified liquid level. In this embodiment, the liquid level detection device is used to detect the liquid level of the dye 211 in the material tank 210. When the liquid level of the dye 211 in the material tank 210 reaches the specified liquid level, the liquid level detection device sends an electrical signal to the control device, and the control device controls the indication device to emit a buzzer and / or light up according to the electrical signal, reminding the staff to perform corresponding processing, such as stopping the replenishment of the dye 211 in the liquid replenishment tube 260, or appropriately discharging the dye 211 in the material tank 210.

[0045] Furthermore, the indicating device includes an indicator light and / or a buzzer.
