When the first adjusting screw 33 is rotated and adjusted according to the width size of the print head 1, the first adjusting screw 33 will adjust the distance between the mounting rail 31 and the sliding adjustment rail 32 when it rotates. After the mounting rail 31 and the sliding adjustment rail 32 are adjusted, the cleaning operator will install the cleaning belt 5 and the fitting pushing mechanism 6 into the mounting rail 31 and the sliding adjustment rail 32. The cleaning belt 5 will be sleeved on the outside of the telescopic rotating shaft 4. Then the cleaning operator will rotate the second adjusting screw 44. When the second adjusting screw 44 rotates, it will drive the first telescopic rotating shaft 42 to telescopically move on the first fixed rotating shaft 41. When the first telescopic rotating shaft 42 extends, the docking groove 421 will be connected to the transmission spraying mechanism 8 for transmission. When the cleaning liquid is delivered to the transmission spraying mechanism 8 by the delivery pump, the transmission spraying mechanism 8 will spray the cleaning liquid onto the cleaning belt 5. When the transmission spraying mechanism 8 sprays, it will drive the telescopic rotating shaft 4 to rotate. When the telescopic rotating shaft 4 rotates, the anti-slip surface 43 will drive the cleaning belt 5 to rotate synchronously. The telescopic rotating shaft 4 can effectively ensure the transmission effect.

The inner wall of the cleaning belt 5 is provided with a plurality of strip-shaped anti-skid grooves 51 , and the interior of the strip-shaped anti-skid grooves 51 is provided with a plurality of flow holes. The outer wall of the cleaning belt 5 is provided with a flexible cleaning layer 52 .

The cleaning liquid is transported to the transmission water spray pipe 81 through the delivery pump. When the transmission water spray pipe 81 transports the cleaning liquid, the cleaning liquid will pass through the rotating joint 811 and enter the interior of the card-connected sliding frame 3. The cleaning liquid entering the interior of the card-connected sliding frame 3 will penetrate into the cleaning belt 5. When the cleaning liquid passes through the rotating blades, the rotating blades will rotate under the influence of the water flow. When the rotating blades rotate, the rotating joint 811 will rotate accordingly. When the rotating joint 811 rotates, the docking transmission shaft 812 is driven to rotate synchronously through the transmission gear. The docking transmission shaft 812 is docked with the docking groove 421 of the telescopic rotating shaft 4. When the docking transmission shaft 812 rotates, it drives the telescopic rotating shaft 4 to rotate synchronously. The telescopic rotating shaft 4 can drive the cleaning belt 5 to rotate synchronously, which effectively saves driving energy. At the same time, the water outlet 82 is connected to another delivery pump. When the transmission water spray pipe 81 transports the cleaning liquid, the other delivery pump can cooperate with the water outlet head 82 to suck the cleaning liquid inside the card-connected sliding frame 3, thereby forming a circulating spray cleaning.

The scraping mechanism 9 includes two mounting blocks 91 mounted on both sides of the inner side of the clamping sliding frame 3 , and a plurality of mounting slots are symmetrically provided on the two mounting blocks 91 , and elastic scraping strips are installed in the corresponding mounting slots on the two mounting blocks 91 .

When the cleaning belt 5 rotates, the cleaning surface of the cleaning belt 5 will frictionally clean the print head 1, and the moving traction frame 7 will drive the card-connected sliding frame 3 to move along the print head 1 and the roller 11. When the card-connected sliding frame 3 moves, the cleaning belt 5 will frictionally clean the surface of the print head 1, and the card-connected sliding frame 3 will also drive the mounting block 91 to move synchronously when moving. The mounting slot of the mounting block 91 is used to install a plurality of elastic scraping strips arranged obliquely. The elastic scraping strips on the mounting block 91 can effectively scrape off the cleaning liquid on the print head 1, thereby improving the cleaning effect.
