A wiping component 8 for wiping the rubber roller 51 is provided on the slide 7.

[0032] The moving mechanism 13 is connected to the mounting frame 12 and drives the mounting frame 12 to move closer to or away from the rubber roller 51.

[0033] The reciprocating mechanism 9 is mounted on the mounting frame 12. The reciprocating mechanism 9 is connected to the slide 7 and drives the slide 7 to move back and forth.

[0034] During operation, the rubber roller 51 to be cleaned is installed on the rotating drum 5. The moving mechanism 13 drives the mounting frame 12 to bring the wiping assembly 8 close to and abut against the rubber roller 51. Through the cooperation of the first reversing valve 33 and the second reversing valve 34, the first reversing valve 33 connects the water suction pipe 42 to the water inlet pipe 31, and the second reversing valve 34 connects the spray pipe 11 to the water outlet pipe 32. The pump body 3 sprays water from the water tank 4 through several nozzles 111 on the spray pipe 11 to the rubber roller 51 for cleaning. The wastewater after cleaning is collected by the collection box 2 at the bottom of the machine casing 1 and filtered through the filter screen 21. The reversing valve 33 connects the filter pipe 22 to the inlet pipe 31, and the second reversing valve 34 connects the supply pipe 41 to the outlet pipe 32. The pump body 3 guides the filtered water from the collection box 2 to the water tank 4 to achieve water recycling and save water resources.

The reciprocating mechanism 9 drives the wiping assembly 8 to move back and forth relative to the rubber roller 51 to achieve comprehensive cleaning of the rubber roller 51. It has the advantages of high automation and high cleaning efficiency.

[0035] Specifically, the rubber roller 51 is provided with a moving shaft 511 and a mounting shaft 512 at both ends, and a bearing 14 is rotatably provided on the housing 1. The bearing 14 has a through hole in the middle for the moving shaft 511 to move through. The rotating drum 5 is detachably connected to the mounting shaft 512.

[0036] When installing the rubber roller 51, first insert the moving shaft 511 of the rubber roller 51 into the bearing 14, and then connect the mounting shaft 512 of the rubber roller 51 to the rotating drum 5 to complete the installation of the rubber roller 51.

[0037] Specifically, the rotating drum 5 is provided with a through hole 52, and a bolt 53 is provided through the through hole 52. The mounting shaft 512 is provided with a mounting hole 5121. The bolt 53 passes through the through hole 52 and the mounting hole 5121, and a nut 54 is threadedly connected to one end of the bolt 53.

[0038] When installing the rubber roller 51, insert the movable shaft 511 into the bearing 14, rotate the drum 5 and move the rubber roller 51 to drive the through hole 52 to align with the mounting hole 5121. Pass the bolt 53 through the through hole 52 and the mounting hole 5121 and tighten it with the nut 54 at one end of the bolt 53 to achieve the detachable installation of the rubber roller 51. The rotating mechanism 6 drives the drum 5 to rotate, which in turn drives the rubber roller 51 to rotate.

[0039] Example 2:

[0040] Reference Figures 1 to 6 In conjunction with the technical solution of Embodiment 1, in this embodiment, the rotating mechanism 6 includes a drive motor 61, a drive gear 62 and a transmission gear 63.

The transmission gear 63 is mounted on the rotating drum 5 and drives the rotating drum 5 to rotate. The drive gear 62 meshes with the transmission gear 63.

[0041] The drive motor 61 drives the drive gear 62 to drive the transmission gear 63 to rotate, which in turn drives the drum 5 to rotate the rubber roller 51, so that the rubber roller 51 can rotate in conjunction with several nozzles 111 and wiping components 8 to clean the rubber roller 51.

[0042] Specifically, the moving mechanism 13 is an electric telescopic rod, which is connected to the mounting frame 12 and drives the mounting frame 12 to move closer to or away from the rubber roller 51.

[0043] When it is necessary to install or remove the rubber roller 51 on the rotating drum 5, the electric telescopic rod drives the mounting frame 12 to move the wiping component 8 away from the rubber roller 51, so as to facilitate the workers to install or remove the rubber roller 51. When the rubber roller 51 needs to be cleaned after it is installed, the electric telescopic rod drives the mounting frame 12 to move the wiping component 8 close to and abut against the rubber roller 51, and the wiping component 8 wipes and cleans the rubber roller 51.

[0044] Specifically, the reciprocating mechanism 9 includes a drive motor 91 and a reciprocating lead screw 92. The drive motor 91 is connected to the reciprocating lead screw 92 and drives the reciprocating lead screw 92 to rotate. The reciprocating lead screw 92 is connected to the slide block 7 and drives the slide block 7 to reciprocate along the axial direction of the reciprocating lead screw 92.

[0045] The drive motor 91 drives the reciprocating screw 92 to rotate. During the rotation of the reciprocating screw 92, the slide block 7 is driven to move back and forth along the axial direction of the reciprocating screw 92, that is, the wiping assembly 8 is driven to move along the circumference of the rubber roller 51, thereby expanding the cleaning area of ​​the rubber roller 51 and achieving comprehensive cleaning of the rubber roller 51.

[0046] Example 3:

[0047] Reference Figures 1 to 6 In conjunction with the technical solutions of Embodiment 1 and Embodiment 2, in this embodiment, the wiping assembly 8 includes a wiping block 81 and a spring 82. The wiping block 81 is movably mounted on the slide 7, and the spring 82 is disposed on the slide 7. The spring 82 abuts against the wiping block 81 and drives the wiping block 81 to extend relative to the slide 7.

[0048] The wiping block 81 is pushed out of the slide block 7 by the spring 82, so that the wiping block 81 elastically abuts against the rubber roller 51, ensuring that the wiping block 81 can remain in close contact with the rubber roller 51 during the movement relative to the rubber roller 51, which is conducive to maintaining the cleaning effect of the wiping block 81.

[0049] Specifically, the wiping block 81 is provided with a sliding rod 811, the sliding rod 811 is provided with an abutment plate 812, the slide block 7 is provided with an installation cylinder 71 for the sliding rod 811 to move and install, the installation cylinder 71 is provided with an abutment part 72 for the abutment plate 812 to abut, and a spring 82 is provided in the inner cavity of the installation cylinder 71. The spring 82 pushes the abutment plate 812 to drive the abutment plate 812 to abut with the abutment part 72.

[0050] Spring 82 pushes the abutment plate 812 to abut against the abutment part 72, so that the wiping block 81 is extended relative to the mounting cylinder 71. In conjunction with the moving mechanism 13, the mounting frame 12 drives the wiping block 81 to move closer to the rubber roller 51, so that the wiping block 81 can elastically abut against the rubber roller 51 to ensure that the wiping block 81 can effectively wipe the rubber roller 51, which helps to improve the cleaning effect of the wiping block 81 on the rubber roller 51.

[0051] Specifically, the wiping block 81 is provided with an arc-shaped groove 813 that abuts against the surface of the rubber roller 51.

[0052] By providing an arc-shaped groove 813 on the wiping block 81 that abuts against the surface of the rubber roller 51, the contact area between the wiping block 81 and the rubber roller 51 is increased, thereby improving the cleaning effect of the wiping block 81 on the rubber roller 51.
