The three rotating rollers 1 are located between the two mounting plates 41, and the connecting shafts 11 at both ends of the rotating rollers 1 are respectively rotatably set on the rotating seats of the two mounting plates 41, and one of the rotating rollers 1 is located between the guiding mechanism 6 and the spray pipe 22.

[0039] Reference Figure 1 The polyester fabric is transported from right to left. The present invention adopts three rotating rollers 1. When the spray head 23 performs spraying and dyeing operations on the transported polyester fabric, two rotating rollers 1 work to assist in the transportation of the polyester fabric. The rotating roller 1 located on the rear side of the spray pipe 22 can contact the surface of the polyester fabric being sprayed and dyed, so a large amount of dye is adhered to the rotating roller 1. The rotating roller 1 located on the front side of the spray pipe 22 contacts the surface of the polyester fabric that has not been sprayed and dyed, so the rotating roller 1 has no dye adhered to it. The last rotating roller 1 can be automatically cleaned by the cleaning mechanism 5 without affecting the transportation operation of the polyester fabric, that is, the polyester fabric can continue to be sprayed and dyed, and the dripping waste dye can be guided to the waste dye area 33 by the guiding mechanism 6 for discharge.

[0050] After the three rotating rollers 1 have completed the replacement operation, the push-down electric push rods 541 on the two locking assemblies 54 work simultaneously, and the push-down electric push rods 541 drive the L-shaped limit block 5422 to move downward, and the L-shaped limit block 5422 drives the locking top block 542 to move downward, and then the locking top block 542 disengages from the insertion groove 523, and the abutment plate 52 loses the locking force, and then the elastic force of the first spring 517 can drive the L-shaped transmission plate 514 to move in the opposite direction, and the L-shaped transmission plate 514 drives the first pulling rod 516 to move in the opposite direction, and the first pulling rod 516 drives the first piston 515 to move in the opposite direction in the first sleeve 511, and the first piston 515 moves in the first sleeve 511. Pressure is applied to form a pulling force, and then the air in the guide mechanism 6 can be drawn into the first sleeve 511, and the two abutment plates 52 drive the synchronous plate 531, the connecting rod 533 and the front plate 532 to move in the opposite direction, and then the arc surface 521 of the abutment plate 52 abuts against the side wall of the mounting plate 41, and the cleaning bristles 534 on the front plate 532 abut against the rotating roller 1 with a large amount of dye adhering to it, and then the new polyester fabric is transported, and the new polyester fabric enters the printing and dyeing box 2 to continue the spraying and dyeing operation. At the same time, the horizontal push electric push rod 551 drives the push plate 5511 to move, and the push plate 5511 drives the L-shaped mounting frame 5523 to move. The servo motor 553 moves synchronously with the L-shaped mounting frame 5523, and the docking sleeve 5531 moves synchronously with the servo motor 553. The docking sleeve 5531 gradually approaches the docking block 12 on the rotating roller 1 to which a large amount of dye is adhered, and then the docking block 12 is directly inserted into the docking groove 5532 of the docking sleeve 5531. Then the servo motor 553 drives the docking sleeve 5531 to rotate, and the docking sleeve 5531 drives the docking block 12 to rotate. The docking block 12 drives the connecting shaft 11 and the rotating roller 1 to rotate on the two mounting plates 41. Then the delivery pump on the detergent storage tank works to deliver the detergent to the spray pipe 5351, and then from all the spray heads 5352 The cleaning agent can be sprayed out, and the cleaning agent can be sprayed onto the rotating roller 1 with a large amount of dye adhered, and then with the cleaning bristles 534, the rotating roller 1 can be gradually cleaned, and then the delivery pump on the clean water storage tank works to deliver the clean water to the water spray pipe 5361, and then it is sprayed out from all the water spray heads 5362, and the clean water can be sprayed onto the rotating roller 1 and the cleaning bristles 534, and then the dirty water on the cleaning brush and the rotating roller 1 can be cleaned off, and the cleaned dirty water can automatically fall into the dirty water area 32. After the rotating roller 1 is cleaned, the push electric push rod 551 drives the push plate 5511 to move in the opposite direction, so that the docking sleeve 5531 is away from the docking block 12.

[0051] When the transmission component 51 is working, it also drives the guiding mechanism 6 to work. The guiding mechanism 6 includes a guide plate 61 and two force-bearing components 62. The two force-bearing components 62 are respectively arranged on the two baffles 3. The guide plate 61 is located between the two baffles 3. The guide plate 61 is arranged at an angle. The guide plate 61 is fixedly connected to the two force-bearing components 62. The bottom of the rear end of the guide plate 61 conflicts with the top of the partition plate 31 located at the middle end. The two force-bearing components 62 are respectively connected to the first connectors 5112 of the two transmission components through pipelines.

[0052] The force-bearing component 62 includes a second sleeve 621, a guide rail 622, an L-shaped connecting block 623 and a linkage plate 624. A second piston 625 is slidably arranged in the second sleeve 621. A second pull rod 626 is arranged at one end of the second piston 625. The second pull rod 626 passes through the outer wall of one end of the second sleeve 621. A second connecting block 6211 and a second connecting head 6212 communicating with the interior thereof are arranged on the outer wall of the second sleeve 621. A second connecting block 6211 and a second connecting head 6212 communicating with the interior thereof are arranged on the inner top wall of the L-shaped connecting block 623. A slide groove, a horizontally arranged fixing rod 6231 is provided on one side wall of the L-shaped connecting block 623, the second connecting block 6211 is fixedly connected to the outer wall of the baffle 3, the guide slide rail 622 is arranged on the top of the baffle 3, the bottom of the L-shaped connecting block 623 is fixedly connected to the tail end of the guide plate 61, the linkage plate 624 is vertically arranged, and one end of the fixing rod 6231 and one end of the second pulling rod 626 are fixedly connected to the linkage plate 624, and the second connecting head 6212 is connected to the first connecting head 5112 through a pipe.

[0053] When the first piston 515 applies an extrusion force to the first sleeve 511, the air in the first sleeve 511 can be squeezed, and then the air can enter the second connector 6212 through the first connector 5112 and the pipeline, and then the air can enter the second sleeve 621, and then the second piston 625 is squeezed by the air entering the second sleeve 621, and the second piston 625 moves in the second sleeve 621, and the second piston 625 drives the second pull-out rod 626 to move, and the movement direction of the second pull-out rod 626 is opposite to that of the first pull-out rod 516, and the second pull-out rod 626 drives the linkage plate 624 to move, and the linkage plate 624 drives the fixed rod 6231 to move synchronously, and the fixed rod 6231 drives the L-shaped connecting block 623 to move on the guide rail 622, and the two L-shaped connecting blocks 623 drive the guide plate 61 to move when moving, and the guide plate 61 gradually moves away from the partition plate 31 at the middle end. In order to ensure the guide The plate 61 does not block the rotation path of the rotating roller 1 to which a large amount of dye is adhered. Therefore, the inner diameter of the first sleeve 511 is set to be larger than the inner diameter of the second sleeve 621, so that when the same air volume enters the second sleeve 621, the moving distance of the second piston 625 is longer, that is, the moving distance of the guide plate 61 is longer than the moving distance of the synchronous plate 531. When the first piston 515 applies a pulling force to the first sleeve 511, the air in the second sleeve 621 can be drawn into the first sleeve 511 through the pipeline, and the second piston 625 in the second sleeve 621 is driven by the pulling force to move in the second sleeve 621 in the reverse direction, and then the guide plate 61 moves in the reverse direction, and then the guide plate 61 is re-contacted with the partition plate 31 at the middle end, and the guide plate 61 is re-covered on the rotating roller 1. The guide plate 61 can not only guide the dripping waste dye to the waste dye area 33, but also block the splashing sewage to prevent the sewage from mixing into the waste dye area 33.

[0054] It is worth noting that the first sleeve 511 and the second sleeve 621 may also contain liquid, and the squeezing force and pulling force generated by the first piston 515 may also allow the liquid to be transferred and transported in the first sleeve 511 and the second sleeve 621 .
