The material suction device 3 is further provided with a first vacuum pump 34 for forming negative pressure in the temporary storage chamber 33, and a first valve 35 for opening or closing a communication pipeline between the temporary storage chamber 33 and the outside. The material returning device 4 is further provided with a second vacuum pump 44 for forming negative pressure in the auxiliary chamber 432, and a second valve 45 for opening or closing a pipeline connecting the auxiliary chamber 432 with the outside. During printing and dyeing, liquid dye 2 is placed in the storage chamber 43, the material suction pipe 31 and the material return pipe 41 are close to each other by taking the conveying belt 1 paved with fabrics as a center until the materials are attached, the first valve 35 is closed, the first vacuum pump 34 is opened to enable the temporary storage chamber 33 to generate negative pressure, and the dye 2 in the storage chamber 43 enters the temporary storage chamber 33 through the material return core 42, the woven fabrics and the material suction core 32; the first vacuum pump 34 is turned off, the second valve 45 is turned off, and the second vacuum pump 44 is turned on to generate a negative pressure in the sub-chamber 432, so that the dye 2 in the temporary storage chamber 33 is returned to the stock chamber 43.

The water-saving and environment-friendly printing and dyeing equipment as claimed in claim 2, further comprising a first sealing gasket 36 fixedly arranged at the lower end of the material suction pipe 31, a second sealing gasket 46 fixedly arranged at the upper end of the material return pipe 41, wherein when the material suction pipe 31 and the material return pipe 41 clamp the conveyer belt 1 paved with the fabric therebetween and are attached together, the lower surface of the first sealing gasket 36 and the lower surface of the material suction core 32 are in the same horizontal plane, and the upper surface of the second sealing gasket 46 and the upper surface of the material return core 42 are in the same horizontal plane, so that the fabric or the conveyer belt 1 can be effectively prevented from moving in the horizontal direction, and a large amount of outside air can be effectively prevented from entering through the material suction pipe 31 or the material return pipe 41 and the contact surface of the fabric or the conveyer belt 1 under the negative pressure condition.

Further, the first sealing gasket 36 includes a first main gasket 361 fixed on the suction pipe 31, and a first auxiliary gasket 362 located below the first main gasket 361 and spaced apart from the first main gasket 361, a first concave groove 363 is disposed on both the lower surface of the first main gasket 361 and the upper surface of the first auxiliary gasket 362, and the first main gasket 361 and the first auxiliary gasket 362 are connected by a first spring 364 having two ends fixed in the first concave groove 363. The first spring 364 is a compression spring, when the first spring 364 is compressed until the first sub-pad 362 contacts with the first main pad 361, the first spring 364 is compressed in the first recess 363, and the lower surface of the first sub-pad 362 is at the same level with the lower surface of the suction core 32.

Further, an upper deflector 365 is disposed on the lower surface of the first main pad 361 and against the wick 32, and a lower deflector 366 is disposed on the inner side surface of the first auxiliary pad 362. In the printing and dyeing process, along with the downward movement of the material suction pipe 31, the first auxiliary pad 362 contacts and fixes the fabric first, then the first main pad 361 contacts with the first auxiliary pad 362 to form a seal, and then the fabric is soaked and dyed back and forth by the dye 2 through negative pressure; after dyeing is completed, the material suction pipe 31 moves upwards, when the first main pad 361 and the first auxiliary pad 362 are separated first, the upward movement is stopped, the first valve 35, the second valve 45 and the second vacuum pump 44 are closed, the first vacuum pump 34 is opened to generate negative pressure, so that outside air enters through a channel generated by separation of the first main pad 361 and the first auxiliary pad 362 and flows through the printed fabric after passing through the upper guide plate 365 and the lower guide plate 366, and excessive liquid on the fabric is removed; finally, the material suction pipe 31 continues to move upwards until the first auxiliary pad 362 is separated from the fabric, and the printed fabric is conveyed away by the conveying belt 1. In order to further increase the contact area between the outside air and the fabric and further improve the control of the dye 2 infiltration range during printing and dyeing, the upper guide plate 365 has an arc surface protruding towards the channel, the lower guide plate 366 has a continuous arc surface protruding towards the channel at the upper side and sinking towards the lower side, and when the first main cushion 361 contacts and closes with the first auxiliary cushion 362, the lowest end a of the upper guide plate 365, the innermost end B of the lower guide plate 366 and the side end C of the lower surface of the material suction core 32 converge at one point.

Further, the second sealing gasket 46 includes a second main gasket 461 fixed on the return pipe 41, and a second sub gasket 462 located above the second main gasket 461 and spaced from the second main gasket 461, wherein a concave second groove 463 is formed on the upper surface of the second main gasket 461 and the lower surface of the second sub gasket 462, and the second main gasket 461 and the second sub gasket 462 are connected by a second spring 464 whose two ends are fixed in the second groove 463.

Further, the upper surface of the second main pad 461 is provided with a lower guide plate 465 abutting on the reclaiming core 42, and the inner side surface of the second sub-pad 462 is provided with an upper guide plate 466. After dyeing is completed, the material returning pipe 41 moves downwards, stops moving upwards when the second main pad 461 and the second auxiliary pad 462 are separated first, and enables outside air to enter by utilizing a channel generated by the separation of the second main pad 461 and the second auxiliary pad 462 through the lower guide plate 465 and the upper guide plate 466 through the dyed fabric through negative pressure, so that the fabric and excessive liquid on the conveying belt 1 are removed; finally, the material return pipe 41 continues to move downwards until the second sub-cushion 462 is separated from the conveying belt 1, and the printed fabric is conveyed away from the conveying belt 1. In order to further increase the contact area between the outside air and the fabric and the conveyor belt 1 and further improve the control of the dye 2 infiltration range during printing and dyeing, the lower guide plate 465 has an arc surface protruding towards the channel, the upper guide plate 466 has a continuous arc surface protruding towards the channel at the lower side and sinking towards the upper side, and when the second main pad 461 contacts and is close to the second auxiliary pad 462, the highest end D of the lower guide plate 465, the innermost end E of the upper guide plate 466 and the side end F of the upper surface of the feed back core 42 converge at one point.

further, the temporary storage chamber 33 and the stock chamber 43 are at normal pressure, and the liquid level of the liquid dye 2 in the stock chamber 43 is lower than the lower surface of the feed back core 42, i.e. there is a gap between the liquid dye 2 and the feed back core 42.

Further, the temporary storage chamber 33 has an hourglass shape, the temporary storage chamber 33 having a narrow neck 331, a lower chamber 332 located below the neck 331, and an upper chamber 333 located above the neck 331, wherein the height of the lower chamber 332 is set small to reduce the capacity of the lower chamber 332, and the height of the upper chamber 333 is set large to secure a sufficient capacity. This facilitates the liquid level to rise rapidly when the dye 2 is sucked into the lower chamber 332 and the neck 331, and facilitates the observation and timely control of the liquid level by a liquid level sensor or naked eyes, thereby saving the amount of the dye 2. In the case where the level of the dye 2 is higher than the neck 331, a sufficient temporary storage space is provided for the dye 2.
