Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] See Figures 1 to 4This embodiment discloses a screen roller cleaning device, including a frame 100. The frame 100 includes two vertically mounted first support plates 110, and a second support plate 120 is mounted on the top of the two first support plates 110. An anilox roller 140 is mounted between the two second support plates 120. A crossbeam 130 is mounted above the anilox roller 140. The second support plates 120 have guide grooves at the beginning, and the crossbeam 130 extends through the guide grooves to the outside of the second support plates 120. A first lead screw assembly 111 is mounted on one side of the second support plate 120. The first lead screw assembly 111 includes a first motor and a first lead screw. The portion of the crossbeam 130 extending to the outside of the second support plate 120 is threadedly engaged with the first lead screw, thereby enabling the first lead screw assembly 111 to drive the crossbeam 130 to move vertically. A second lead screw assembly 131 is mounted on the crossbeam 130. The second lead screw assembly 131 includes a second motor and a second lead screw. The second lead screw is threadedly engaged with a moving block 200, thereby driving the moving block 200 to move horizontally. A first liquid storage tank 210 and a second liquid storage tank 220 are respectively mounted on both sides of the moving block 200 in the width direction. Spray nozzles 240 are mounted on the bottom of the first liquid storage tank 210 and the second liquid storage tank 220, so that the liquid in the first liquid storage tank 210 and the second liquid storage tank 220 can be sprayed out. A first liquid inlet 211 is provided on the top of the first liquid storage tank 210, and a second liquid inlet 221 is provided on the top of the second liquid storage tank 220. The first liquid inlet 211 is connected to a first pipe 201, which is connected to an external water source, so that the cleaning mechanism can rinse the anilox roller 140 with water, thereby cleaning the anilox roller 140. The second liquid inlet 221 is connected to the second pipe 202, which is connected to an external cleaning agent, so that the nozzle 240 at the bottom of the second liquid tank 220 can spray cleaning agent onto the anilox roller 140, thereby improving cleaning efficiency.

[0019] A support block 230 is connected to the bottom of the movable block 200. The support block 230 has a mounting groove with its opening facing downwards. A second drive mechanism is installed in the mounting groove. The second drive mechanism includes a support frame 400, which includes a horizontally arranged first plate 410. Second plates 420 extending downwards are provided at both ends of the first plate 410. The cleaning roller 300 is installed between the two second plates 420. Simultaneously, a third lead screw assembly 235 is installed in the mounting cavity 231. The third lead screw assembly 235 includes a third motor and a third lead screw. The third lead screw extends vertically and is threaded into the first plate 410, thereby enabling the third lead screw assembly 235 to drive the support frame 400 to move vertically and to raise and lower the cleaning roller 300. A guide rod 232 is provided inside the mounting cavity 231, passing through the first plate 410. A limit plate 233 is provided at the end of the guide rod 232, and a spring 234 is sleeved on the guide rod 232. The two ends of the spring 234 abut against the first plate 410 and the limit plate 233, respectively. The spring 234 can buffer the movement of the cleaning roller 300 during lifting and lowering, thereby ensuring the stability of the lifting and lowering of the cleaning roller 300.

[0020] During cleaning, the crossbeam 130 is first moved downwards to lower the cleaning roller 300 above the anilox roller 140. The cleaning roller 300 is a roller with a fabric-covered surface. Moving the cleaning roller 300 downwards brings it into contact with the anilox roller 140, causing the anilox roller 140 to rotate and thus cleaning it. After cleaning a section of the anilox roller 140, the cleaning roller 300 rises, the moving block 200 moves horizontally, and then the cleaning roller 300 descends to clean the remaining portion of the anilox roller 140. The cleaning roller 300 effectively removes any residual paint from the surface of the anilox roller 140. After cleaning, the cleaning roller 300 retracts between the first liquid storage tank 210 and the second liquid storage tank 220. Then, the nozzle 240 below the second liquid storage tank 220 sprays the cleaning agent onto the anilox roller 140. As the moving block 200 moves, the cleaning agent can cover the entire anilox roller 140. After standing for two minutes, clean water is sprayed onto the anilox roller 140 through the nozzle 240 at the bottom of the first liquid storage tank 210, thus completing the cleaning of the anilox roller 140.
