[0002] In the production process of UV inks, the grinding of raw materials is a crucial step. UV inks, a special type of ink that cures rapidly under ultraviolet light, are widely used in food, pharmaceutical, and cosmetic packaging, as well as high-end printing. Their production process typically includes multiple steps such as raw material preparation, color matching, filtration, mixing, stirring, grinding, correction, filling, and packaging. Among these, the grinding step uses a grinding mill to refine the uniformly mixed raw materials, thereby improving the ink's color accuracy and texture.

[0003] In existing technologies, UV inks are mostly ground using three-roll mills and single-roll mills. However, in actual production, the raw materials may contain stones or other hard impurities. These impurities can cause friction and damage to the surface of the grinding roller during the grinding process, resulting in pits and unevenness, which in turn affects the fineness and uniformity of the ink.

[0022] A feeding hopper 5 is fixedly connected to the upper surface of the grinding machine housing 1. An inverted U-shaped plate 6 is fixedly connected to the upper surface of the grinding machine housing 1. A motor protective shell 7 is fixedly connected to the upper surface of the inverted U-shaped plate 6. A servo motor 8 is installed on the upper surface of the inverted U-shaped plate 6. A first rotating shaft 9 is installed at the output end of the servo motor 8.

[0023] The bottom end of the first rotating shaft 9 is rotatably connected to the grinding machine housing 1. The outer surface of the first rotating shaft 9 is fixedly connected to the first gear 10. The outer surface of the first gear 10 is meshed with the second gear 11. The bottom surface of the second gear 11 is fixedly connected to the second rotating shaft 12. The second rotating shaft 12 is rotatably connected to the inside of the grinding machine housing 1. The bottom end of the second rotating shaft 12 is fixedly connected to the grinding roller 3.

[0024] The bottom end of the grinding roller 3 is fixedly connected to a third rotating shaft 13, the bottom end of the third rotating shaft 13 is rotatably connected to the grinding machine housing 1, and a set of crushing blades 14 are fixedly connected to the outer surface of the third rotating shaft 13. Two D-shaped discharge ports are opened at the bottom of the grinding machine housing 1.

[0025] A support rod 15 is fixedly connected to the bottom surface of the grinding machine housing 1, and a base plate 16 is fixedly connected to the bottom end of the support rod 15.

[0026] The bottom surface of the base plate 16 is fixedly connected with four support feet 18, and the upper surface of the base plate 16 is fixedly connected with a discharge plate 17.

[0027] Two of each of the U-shaped part 403, round pin 404, rotating block 405, lead screw 406, and throttle 407 are provided, and each is located on the side of the grinding strip 402 away from the grinding roller 3. At the same time, the shape of the grinding strip 402 is set to be arc-shaped to seal with the slide groove 401, and the fit is tight.

[0028] There are four support rods 15, which are located at the four corners between the base plate 16 and the grinding machine housing 1.

[0029] By setting up the grinding mechanism 4, the problem of damage to the grinding roller 3 due to long-term use or friction from impurities can be effectively solved. The grinding mechanism 4 includes a sliding groove 401, a grinding strip 402, a U-shaped part 403, a round pin 404, a rotating block 405, a lead screw 406, and a throttle 407. By adjusting the grinding mechanism 4, the grinding roller 3 can be precisely ground to remove pits and damage on its surface, effectively improving grinding efficiency, thereby improving the fineness and uniformity of the ink and ensuring the production quality of UV ink.

[0030] By setting the crushing blade 14 and the D-shaped discharge port, the grinding effect and production efficiency are further improved. The crushing blade 14 is fixed on the third rotating shaft 13 and rotates together with the grinding roller 3 to perform final fine grinding on the raw materials, ensuring the fineness and quality of the ink. At the same time, the design of the D-shaped discharge port allows the fine ink slurry after grinding to flow out smoothly, improving the discharge efficiency and facilitating subsequent collection and processing.

[0031] Working Principle: When grinding UV ink raw materials using this grinding machine, the ink raw materials to be ground are first added to the grinding chamber 2 through the feeding hopper 5. Then, the servo motor 8 is started, and its output drives the first rotating shaft 9 to rotate. Since the first gear 10 is fixedly connected to the first rotating shaft 9, the rotation of the first gear 10 drives the meshing second gear 11 to rotate, which in turn drives the second rotating shaft 12 and the grinding roller 3 to rotate, thus grinding the ink raw materials. The crushing blade 14 is fixed on the third rotating shaft 13 and rotates together with the grinding roller 3, thus performing final fine grinding of the raw materials. After grinding, to remove pits and damage from the surface of the grinding roller 3, the grinding mechanism 4 can be adjusted to polish the grinding roller 3. Specifically, by simultaneously rotating the two handles 407, the lead screw 406 rotates under the action of the threaded connection and moves axially, pushing the rotating block 405, the round pin 404, and the grinding strip 402 to move towards the grinding roller 3 within the sliding groove 401. When the grinding strip 402 comes into contact with the grinding roller 3, the angle of one end of the grinding strip 402 can be changed by adjusting a single throttle 407 to ensure close contact with the grinding roller 3. Then, the servo motor 8 is started to drive the grinding roller 3, thus achieving grinding of the grinding roller 3. After grinding, the ground ink paste will flow out through the D-shaped discharge port at the bottom of the grinding machine housing 1 and be collected and further processed by the discharge plate 17. In addition, the grinding machine has a reasonable structural design, providing stable support through the support rod 15 and the base plate 16, ensuring the smooth operation of the grinding process.
