[0028] The working principle of the utility model is as follows: when cleaning the ink roller for printing, the ink roller is first installed in the cleaning box 1, the second rotating shaft 23 at one end of the ink roller 22 is inserted into the first rotating shaft 21 on the left, and then the second electric telescopic rod 42 is started to move toward the ink roller 22, driving the first rotating shaft 21 on the right to be inserted into the other second rotating shaft 23, thereby completing the installation of the ink roller 22. When installing the ink roller 22, the bottom of the ink roller 22 presses the pressing brush assembly 5 below, and the brush assembly 5 below presses the pre-tightening assembly 8, so that the brush 53 below abuts against the ink roller 22 to clean the ink roller 22. After cleaning, the motor 3, the water pump 102 and the first electric telescopic rod 7 are started. The motor 3 drives the ink roller 22 to rotate, and the water pump 102 sprays the cleaning liquid onto the top of the ink roller 22. At the same time, the first electric telescopic rod 7 drives the brush assembly 5 above to move down to the upper ink feed roller 22 of the ink roller 22 for cleaning. The upper and lower groups of brush assemblies 5 clean the ink roller 22 at the same time, so that the cleaning efficiency is better and the cleaning effect is better. The used cleaning liquid will fall on the filter screen 106, and after the impurities are filtered out by the filter screen 106, it will flow into the bottom of the cleaning box 1, and can be recycled again, which is more energy-saving. When the ink roller 22 is cleaned, the second electric telescopic rod 42 is started to move to the right side, so that the second rotating shaft 23 above the ink roller 22 is moved out from the first rotating shaft 21. Through the spline connection between the first rotating shaft 21 and the second rotating shaft 23, quick disassembly and assembly can be achieved to improve the cleaning efficiency. When the brush 53 is worn out after being used for a period of time and needs to be replaced, the push rods 62 on both sides are pressed, and the push rods 62 push the limit plate 63, the connecting rod 64 and the latch 66 to move. When the latch 66 is removed from the slot 521 on the second connecting plate 52, the second connecting plate 52 and the brush 53 can be removed, and the brush 53 can be replaced. The operation is very convenient.
