[0002] An ink cleaning device for green environmental protection printing is a printing ink cleaning equipment aiming to reduce environmental pollution and improve resource utilization efficiency. Such devices usually combine a variety of environmental protection and energy-saving technologies to ensure reducing the emissions of waste water and waste gas during the cleaning process and realizing the recycling of ink as much as possible.

[0003] According to CN202222105141.2 disclosed in the Chinese patent, in this application document, the ink bucket is placed in the cleaning box, and the exhaust gas is filtered by the filter and then discharged; the limiting plate fixes the ink bucket to prevent it from moving; the spray pipe injects the cleaning liquid into the ink bucket, and then the brush strip cleans the inner wall of the ink bucket; the bracket is detachably connected to the rotating shaft for easy replacement to adapt to ink buckets of different diameters;

[0004] Although the spray pipe in the application document can effectively handle the problem of poor cleaning effect, during the operation process, it is necessary to ensure that the ink roller is deeply immersed in the highly efficient cleaning agent during continuous rotation until most of the ink residues attached to its surface are effectively dissolved and peeled off. However, in the face of those particularly stubborn ink spots that are difficult to leave easily, they often still stubbornly adhere to the ink roller. Therefore, we propose an ink cleaning device for green environmental protection printing. Content of the Utility Model

A cleaning tank 2 is provided at the top of the cleaning box 1. The inner wall of the cleaning tank 2 is sleeved with an ink roller 3 through a connecting shaft. One end of the connecting shaft penetrates through one side of the cleaning box 1 and is fixedly connected to a servo motor 4. One side of the servo motor 4 is movably connected to the outside of the cleaning box 1. It further includes:

[0027] A cleaning structure arranged outside the ink roller 3, which is used to wipe the ink on the surface of the ink roller 3;

[0028] A driving structure arranged on the inner wall of the bottom of the cleaning tank 2, which is used to adjust the position of the cleaning structure.

[0029] Further, the driving structure includes a fixed component 5, a hydraulic rod 6, and a wedge-shaped slider 9. The bottom inner wall of the cleaning tank 2 is fixedly connected to the fixed component 5. One side of the fixed component 5 is fixedly connected to the hydraulic rod 6 through a connecting rod. The other end of the hydraulic rod 6 is fixedly connected to the wedge-shaped slider 9. When the hydraulic rod 6 is started, the hydraulic rod 6 extends, pushing the wedge-shaped slider 9 to slide in the first trapezoidal chute 8. Due to the special shape of the wedge-shaped slider 9, it is in the shape of a right trapezoid and fits with the first trapezoidal chute 8.

[0030] Further, a first fixing block 7 is fixedly connected to the position on the bottom inner wall of the cleaning tank 2 away from the fixed component 5. The top of the first fixing block 7 is provided with a first trapezoidal chute 8, and the inner wall of the first trapezoidal chute 8 is clamped with the bottom of the wedge-shaped slider 9.

[0031] Further, one side of the top of the first fixing block 7 is fixedly connected to a second trapezoidal chute 16. The inner wall of the second trapezoidal chute 16 is clamped with a second lifting block 15. The outside of the second lifting block 15 is fixedly connected to a first lifting block 10. The top of the first lifting block 10 is fixedly connected to a first group of auxiliary blocks 11 through a connecting column. The top of the first group of auxiliary blocks 11 is sleeved with a first group of cleaning rollers 12 through a fixed shaft. The outside of the first group of cleaning rollers 12 is movably connected to the outside of the ink roller 3. The sliding of the wedge-shaped slider 9 will be converted into the vertical movement of the first lifting block 10 and the second lifting block 15. The upward movement of the first lifting block 10 drives the first group of auxiliary blocks 11 and the first group of cleaning rollers 12 fixed thereon to move upward until the first group of cleaning rollers 12 is in contact with the surface of the rotating ink roller 3.

[0032] Further, rollers 17 are movably connected to both sides of the first lifting block 10. A connecting shaft 14 is inserted into the axis of the roller 17. Both ends of the connecting shaft 14 are fixedly connected to movable blocks 18. One end of the connecting shaft 14 penetrates the outside of the movable block 18, and one end of the connecting shaft 14 is fixedly connected to a spring 13. When the first lifting block 10 rises, due to the trapezoidal shape of the first lifting block 10 and the arrangement of the rollers 17, the rollers 17 will slide downward on the outside of the first lifting block 10, making the distance between the two groups of rollers 17 wider, and the spring 13 performs an unfolding operation. When the two groups of rollers 17 move downward, they drive the movable block 18 to expand outward.

[0033] Further, the other end of the movable block 18 is fixedly connected to two groups of first connecting blocks 19. A second connecting block 20 is movably connected between the two groups of first connecting blocks 19 through a connecting shaft. One end of the second connecting block 20 is fixedly connected to a second fixing block 21. One side of the second fixing block 21 is fixedly connected to the inner wall of the cleaning tank 2. The movable block 18 is fixedly connected to the second group of auxiliary blocks 11 through the first connecting block 19, and with the first connecting block 19 as the support point, when the movable block 18 expands outward, the first group of auxiliary blocks 11 and the cleaning rollers 12 move towards the ink roller 3 until they are in contact with the outside of the ink roller 3.

[0034] Furthermore, the cleaning structure includes an auxiliary block 11 and a cleaning roller 12. The tops of two groups of first connecting blocks 19 are fixedly connected with a second group of auxiliary blocks 11. The top of the second group of auxiliary blocks 11 is sleeved with a second group of cleaning rollers 12 through a fixed shaft. The outer side of the second group of cleaning rollers 12 is movably connected with the outer side of the ink roller 3. The movable block 18 and the second group of auxiliary blocks 11 are fixedly connected together through the first connecting block 19. And with the first connecting block 19 as the support point, when the movable block 18 expands outwards, the first group of auxiliary blocks 11 and the cleaning roller 12 move towards the ink roller 3 until they are in contact with the outer side of the ink roller 3. After confirming that both groups of cleaning rollers 12 are in good contact with the ink roller 3, start the servo motor 4. The servo motor 4 drives the ink roller 3 to rotate in the cleaning tank 2 through the connecting shaft. A relative movement is generated between the rotating ink roller 3 and the cleaning rollers. The ink on the surface of the ink roller 3 is wiped off through physical friction. After a period of cleaning, the ink on the surface of the ink roller 3 is effectively wiped off, achieving the cleaning purpose.

[0035] Working principle:

[0036] The cleaning tank 2 in the cleaning box 1 is ready. The ink roller 3 is sleeved in the cleaning tank 2 through the connecting shaft. The servo motor 4 is connected to the connecting shaft to ensure that it can drive the ink roller 3 to rotate. Start the hydraulic rod 6. The hydraulic rod 6 extends, pushing the wedge-shaped slider 9 to slide in the first trapezoidal chute 8. Due to the special shape of the wedge-shaped slider 9, which is a right trapezoid and matches with the first trapezoidal chute 8, the sliding of the wedge-shaped slider 9 will be converted into the vertical movement of the first lifting block 10 and the second lifting block 15. The upward movement of the first lifting block 10 drives the first group of auxiliary blocks 11 and the first group of cleaning rollers 12 fixed thereon to move upwards until the first group of cleaning rollers 12 are in contact with the surface of the rotating ink roller 3. When the first lifting block 10 rises, due to the trapezoidal shape of the first lifting block 10 and the arrangement of the rollers 17, the rollers 17 will slide downwards on the outer side of the first lifting block 10, making the distance between the two groups of rollers 17 wider, and the spring 13 performs an unfolding operation. When the two groups of rollers 17 move downwards, they drive the movable block 18 to expand outwards. The movable block 18 and the second group of auxiliary blocks 11 are fixedly connected together through the first connecting block 19. And with the first connecting block 19 as the support point, when the movable block 18 expands outwards, the first group of auxiliary blocks 11 and the cleaning roller 12 move towards the ink roller 3 until they are in contact with the outer side of the ink roller 3. After confirming that both groups of cleaning rollers 12 are in good contact with the ink roller 3, start the servo motor 4. The servo motor 4 drives the ink roller 3 to rotate in the cleaning tank 2 through the connecting shaft. A relative movement is generated between the rotating ink roller 3 and the cleaning rollers. The ink on the surface of the ink roller 3 is wiped off through physical friction. After a period of cleaning, the ink on the surface of the ink roller 3 is effectively wiped off, achieving the cleaning purpose.
