[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a grinding machine for producing ink, comprising a grinding cylinder and an upper cover, the upper cover is rotatably connected to the top of the grinding cylinder, a feed port is provided at the center position of the upper cover, a support column is fixedly connected to the bottom of the upper cover, a grinding block is fixedly connected to the bottom of the support column, wherein the support column is provided with four fixedly connected to the top of the grinding block at equal distances in a circular arrangement order, the grinding block is arranged inside the grinding cylinder, a drop groove is provided on the top of the grinding block, wherein the drop groove is a frustum groove structure, a feed port is provided in the middle position of the grinding block, a grinding table is fixedly connected to the top of the bottom of the grinding cylinder, the lower end of the upper cover is attached to the bottom of the grinding cylinder, the frustum groove structure of the bottom of the upper cover is attached to the outside of the grinding table, the outer wall of the grinding block is attached to the inner wall of the grinding cylinder, and the outer wall of the grinding block is provided with a feed groove.
[0006] By adopting the above technical solution, when grinding the ink, the ink is poured into the feed port, and then the ink flows into the discharge port through the feed port. After the ink enters the bottom of the grinding block, the grinding block at the bottom is driven to rotate by rotating the upper cover, and the ink is ground by the rotation of the grinding block. The ground ink enters the feeding trough along the outside of the grinding block. Since the feeding trough is set to a spiral upward structure, the spiral structure of the feeding trough will drive the ink to move upward when the grinding block rotates. When the ink moves to the top of the grinding block, the ink will move along the drop trough toward the inside of the discharge port, and then be ground again. The ink is repeatedly ground to ensure that the overall ink is fine and free of particles.

[0016] By adopting the above technical solution, when the ink grinding is completed, the ink can be discharged outward through the discharge port, and the ink container is placed directly below the discharge hopper to collect the ground ink.
[0017] As an optimal technical solution of the present application, a sliding cover groove is provided on the outside of the discharge port, a sliding groove is provided on the side of the sliding cover groove, a sealing cover is slidably connected inside the sliding cover groove, a fastening bolt is rotatably connected to the outside of the sealing cover, and a rubber pad is provided on the side of the sealing cover close to the discharge port.
[0018] By adopting the above technical solution, the setting of the sliding groove enables the sealing cover to slide inside the sliding groove. When the ink is not completely ground, the sealing cover moves to the outside of the discharge port. By rotating the fastening bolt, the end of the fastening bolt pushes the rubber pad on the back of the sealing cover to seal the discharge port to prevent ink leakage. When the grinding is completed, the fastening bolt is unscrewed in the reverse direction until the sealing cover can slide freely outside the sliding groove, and then the sealing cover is slid to the top of the discharge port, and the fastening bolt is turned again so that the end of the fastening bolt can fit the rubber layer tightly inside the sliding groove, thereby limiting the movement of the sealing cover.

In the present invention, during the grinding process, after the ink is squeezed by the grinding block, it will move upward along the feeding trough on the outside of the grinding block in a spiral, which enables the ink to form a circulating flow during the grinding process, thereby increasing the contact time and contact area between the ink and the grinding block and the grinding table, and also improving the uniformity and fineness of the grinding. When the ink reaches the top of the grinding block, it will flow back to the discharge port through the drop trough for re-grinding, ensuring that the ink can be fully ground to achieve the required fineness.
