[0032] Working principle: When using this device, the water-based ink color paste raw material can be injected into the grinding box 1 from the feed pipe 26, and the second motor 27 is started. The output end of the second motor 27 will drive the gear 28 to rotate. Since the two gears 28 are engaged, the two gears 28 will rotate. The rotation of the gear 28 will drive the grinding roller 15 to rotate to grind the color paste raw material. The ground color paste will fall into the first collecting box 24 for collection. After the grinding work is completed, the first collecting box 24 can be pulled out to collect the ground color paste. When different colors of color pastes need to be ground, it is necessary to ensure that the surfaces of the two grinding rollers 15 are clean to avoid color mixing. At this time, the second collecting box 25 can be placed at the drain outlet of the grinding box 1, and the water pipe 29 can be connected to the supply On the water pump of the water equipment, start the first motor 2, and the output end of the first motor 2 will drive the bidirectional screw rod 3 to rotate, and the bidirectional screw rod 3 will drive the two screw nuts 4 to approach each other, and the screw nuts 4 will drive the first set of plates 5 to move, and the first set of plates 5 will drive the guide plate 6 to move, and the two guide plates 6 will approach each other, and the guide plate 6 will drive the third set of plates 18 to move along the third guide rod 19, which can ensure the stability of the guide plate 6 when moving, and the two guide plates 6 will approach each other until they contact each other. By setting a sealing gasket, it is ensured that the guide plate 6 is tightly fitted with the inner wall of the grinding box 1, and it is also ensured that the two guide plates 6 can be tightly fitted. When the guide plate 6 moves, it will also drive the U-shaped plate 10 to move, and the U-shaped plate 10 will drive the support rod 11 to move, and the support rod 11 will move. The support rod 11 will drive the second set of plates 12 to move, and the second set of plates 12 will drive the nozzle 13 to move, so that the two nozzles 13 are close to each other until they move to the top of the grinding roller 15. When the guide plate 6 moves, the extrusion plate 7 will also be driven to move. The extrusion plate 7 will contact the inner wall of the guide plate 9. The two extrusion plates 7 continue to move close to each other and squeeze the guide plate 9 so that the guide plate 9 moves away from the grinding box 1. The guide plate 9 will drive the first sealing plate 8 to move, and the drain port of the grinding box 1 can be exposed. The movement of the first sealing plate 8 will also drive the fourth set of plates 20 to move along the fourth guide rod 21. The fourth set of plates 20 will squeeze the spring 22 to contract the spring 22. At this time, the water pump in the water supply equipment is started to pump water from the water tank of the water supply equipment and transport it to the nozzle 13. The high-pressure water flow is sprayed out through the nozzle 13 and sprayed on the grinding roller 15, so that the grinding roller 15 continues to rotate, so that the water can rinse the grinding roller 15, and the rinsed water will fall on the guide plate 6, flow through the guide plate 6 to the drain outlet of the grinding box 1, and then flow out of the drain outlet and fall into the second collection box 25 to be collected. After the cleaning is completed, the output end of the first motor 2 is reversed, and the bidirectional screw 3 is reversed, so that the two guide plates 6 can be moved away from each other, and the two nozzles 13 can be moved away from each other, which can make the second sealing plate 14 contact with the box body 23 again to seal the box body 23. At the same time, the guide plate 6 will also drive the extrusion plate 7 to return to the initial position and no longer squeeze the guide plate 9. The spring 22 will stretch to make the fourth set of plates 20 return to the initial position.The first sealing plate 8 can then seal the drain port of the grinding box 1 again. At this point, the grinding box 1 can be left alone or dried with a blower to continue grinding.
