[0035] like Figure 1 , Figure 2As shown, two groups of support blocks 2 are fixedly installed on the top of the workbench 1, and auxiliary rollers 3 are movably inserted between the inner walls of the two groups of support blocks 2. A support frame 4 is fixedly installed on the top of the workbench 1, and a mounting plate 5 is movably embedded in the inner wall of the support frame 4. A pressing block 6 is fixedly installed on the bottom of the mounting plate 5. Under the action of the auxiliary rollers 3, the friction of the printed article can be reduced to avoid damage to the printed article during printing.

[0036] like Figure 1 , Figure 2 and Figure 6 As shown, two compression springs 7 are fixedly installed on the top of the mounting plate 5, and the top of the compression spring 7 is fixedly connected to the top of the inner wall of the support frame 4, and a bottom plate 49 is fixedly installed on the top of the workbench 1. Two embedded grooves 26 are provided on the inner surface wall of the outer shell 25. Under the action of the compression spring 7, the mounting plate 5 can be moved downward and with the cooperation of other mechanisms, the printed article can be made close to the bottom plate 49 to avoid wrinkles on the printed article and friction on the nozzle, thereby protecting the nozzle.

[0037] like Figure 6 As shown, a slide 27 is movably embedded between the inner walls of the two embedded grooves 26, and a second telescopic rod 28 is fixedly connected to one side of the outer wall of the slide 27. A fixed groove 29 is opened on one side of the outer wall of the slide 27. Under the action of the second telescopic rod 28, the slide 27 can be driven to move inside the embedded groove 26.

[0038] like Figure 6 As shown, a third telescopic rod 30 is fixedly inserted into the inner surface wall of the fixing groove 29, and a first gear 31 is fixedly sleeved on the telescopic end of the third telescopic rod 30. During use, the third telescopic rod 30 can drive other structures to move up and down, thereby improving the use effect.

[0039] like Figure 6 As shown, the telescopic end of the third telescopic rod 30 is fixedly sleeved with a bearing 32, the outer wall of the bearing 32 is fixedly sleeved with a connecting plate 33, and the top of the connecting plate 33 is fixedly connected to the outer wall of the conveying pipe 11, and a plurality of nozzle bodies 34 are fixedly installed at the bottom of the connecting plate 33, and the nozzle bodies 34 and the connecting plate 33 are in a connected state. Under the action of the bearing 32, the connecting plate 33 can reduce the friction between the components when rotating, thereby extending its service life.

[0040] like Figure 6 As shown, a first motor 35 is fixedly mounted on one side of the outer wall of the connecting plate 33, and a second gear 36 is fixedly sleeved on the output end of the first motor 35, and the outer wall of the second gear 36 is meshedly connected with the outer wall of the first gear 31. The first motor 35 can be used as a power output, and under the action of the first gear 31 and the second gear 36, the connecting plate 33 can be driven to rotate.

[0041] The working principle of the whole mechanism is as follows: when the printing equipment is required to print the paper, the ink delivery pipe 18 and the water delivery pipe 12 are first connected to the external ink storage box and the liquid storage box under the operation of the staff, and the drainage pipe 41 is connected to the external collection box, and then the mounting plate 5 is pushed to move upward inside the support frame 4, and then the paper to be printed passes between the pressing block 6 and the bottom plate 49 to reach the other side of the printing equipment, and the paper is fixed to the external transmission device. The operation of the transmission device can drive the paper to continue to move, and at the same time, under the action of the second telescopic rod 28, the slide 27 is driven to move inside the embedded groove 26, thereby driving the nozzle to move to a suitable position, and then under the action of the third telescopic rod 30, the nozzle is driven to move downward to a suitable position. The ink in the external ink tank is sucked out by the delivery pump 19 and delivered to the inner tube 16 through the ink delivery tube 18. Since the inner tube 16 and the outer tube 10 are connected, the ink passes through the outer tube 10 and the delivery tube 11 to reach the inside of the connecting plate 33 and is finally ejected from the nozzle to complete the printing process of the paper. When the paper is printed, the delivery pump 19 stops working and no longer delivers the ink. Then, the second gear 36 is driven to rotate by the first motor 35. At the same time, the connecting plate 33 and the nozzle are driven to rotate to a suitable angle by the first gear 31. Then, the connecting plate 33 and the nozzle body 34 are driven to move upward to a suitable position by the third telescopic rod 30 and are moved to the second telescopic rod 35. Under the action of the rod 28, the slide 27 is driven to move inside the embedded groove 26, thereby driving the nozzle to move to the top of the first cleaning box 38, and then under the action of the third telescopic rod 30, the nozzle is driven to move downward to the inside of the first cleaning box 38, and the two valves 42 are closed. Then, under the action of the first telescopic rod 15, the movable plate 14 is driven to move upward, thereby driving the inner tube 16 to move upward to a suitable position inside the outer tube 10, so that the inner tube 16 no longer squeezes the first wedge block 22. At the same time, under the action of the limit spring 21, the first wedge block 22 is driven to move inside the installation box 20 toward the middle of the outer tube 10, so that the outer tube 10 is closed, and under the action of the second sealing ring 23, the two first wedge blocks 22 can be connected more tightly. Then, under the action of the water pump 13, the cleaning liquid inside the external liquid storage tank is sucked out, and is transported to the inside of the outer tube 10 through the water delivery pipe 12, and at the same time reaches the inside of the connecting plate 33 through the delivery pipe 11, and is sprayed out from the nozzle and enters the first cleaning box 38. When the cleaning liquid inside the first cleaning box 38 reaches a certain amount, the ultrasonic generator 39 generates sound waves to vibrate the cleaning liquid inside the first cleaning box 38, and cleans the ink retained in the nozzle. When the ink retained in the nozzle is cleaned, the third telescopic rod 30, the slide 27 and the second telescopic rod 28 cooperate with each other to drive the nozzle to move to the inside of the second cleaning box 40 and contact the surface of the cleaning wheel 47. When the nozzle is in motion, the water pump 13 stops working.The delivery of the cleaning liquid is thereby stopped. When the nozzle moves into the second cleaning box 40, the water pump 13 works again to deliver the cleaning liquid into the second cleaning box 40. At the same time, under the action of the second motor 43, the threaded rod 46 is driven to rotate, and the movable block 45 is driven to move in the movable groove 44, thereby driving the cleaning wheel 47 to move in the second cleaning box 40. When the cleaning wheel 47 moves in the second cleaning box 40, the cleaning wheel 47 itself can be rotated by the action of the meshing groove opened in the transmission wheel 48 and the movable groove 44, thereby completing further cleaning of the outer wall of the nozzle to prevent the ink attached to the outer wall of the nozzle from solidifying and affecting subsequent use. After the nozzle of the printing equipment is cleaned, it is dried by a special drying device, and under the operation of the staff, the valve 42 is opened to allow the first cleaning box 38 to be cleaned. The sewage inside the second cleaning box 40 is sent from the drain pipe 41 to the external collection box for centralized collection and treatment, so as to avoid the sewage from causing serious impact on the environment around the equipment. When the nozzle is cleaned, when the paper needs to be printed again, the nozzle is transported to a suitable position through the above structure and method, and then under the action of the first telescopic rod 15, the movable plate 14 is driven to move downward inside the mounting frame 8, so that the inner tube 16 moves downward inside the outer tube 10. Under the action of the second wedge block 24, the two first wedge blocks 22 can be squeezed and separated, so that the inner tube 16 is connected with the outer tube 10, so that the ink can pass through the outer tube 10 and the inner tube 16 smoothly. At the same time, under the action of the first sealing ring 17, the ink can be prevented from entering the water pipe 12. Finally, the paper can be printed again through the above structure and method.
