[0032] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0033] like Figures 1 to 5 As shown, the embodiment of the utility model provides a raw material grinding device for printing ink production, including a feed hopper 1, a grinding bin 2, a filter plate 3, a rolling and grinding mechanism 4, a rotating material disc 5, a sweeping baffle 6 and a discharge trough 7;

The rolling and grinding mechanism 4 is arranged in the grinding chamber 2 to roll and grind the printing ink raw material in the grinding chamber 2. In the grinding chamber 2, the ink raw material will be ground by the rolling and grinding mechanism 4 to obtain ink raw material with small particle size and uniformity.

[0035] like Figure 2 and Figure 5As shown, further, a cone structure 11 is provided inside the feed hopper 1, and the cross-sectional area of ​​the cone structure 11 gradually increases from top to bottom. The cone structure 11 is used to guide the ink raw material to flow evenly, and a plurality of discharge ports 12 are provided along the circumferential direction at the bottom of the cone structure 11. The setting of the cone structure 11 can make the ink raw material fall more smoothly and evenly during the falling process, avoiding material blockage, and the discharge ports 12 are spaced apart along the circumferential direction of the bottom of the cone structure 11, which can improve the uniformity of the ink raw material falling and avoid material accumulation affecting the grinding efficiency.

When the ink raw material on the discharge trough 7 falls into the gap between the grinding rollers 84, the ink raw material will be squeezed, ground and sheared, and finally reach the required degree of refinement, and the particle size is more uniform, which effectively improves the quality of the ink.

[0043] like Figure 4As shown, further, the roller grinding mechanism 8 also includes a bearing slide 85, a spring member 86, a cover 87 and an adjusting screw 88; the bearing slide 85 is arranged at both ends of the grinding roller 84, a slide rail 89 is arranged on the frame 81, and the bearing slide 85 can slide along the length direction of the slide rail 89, a spring member 86 is arranged between two adjacent grinding rollers 84, and the spring member 86 is used to apply elastic force to separate the two grinding rollers 84 from each other, the cover 87 is covered on the shaft end of the grinding roller 84, and the adjusting screw 88 passes through the cover 87 and abuts against the bearing slide 85 at the side end of the frame 81, and the adjusting screw 88 is used to adjust the size of the gap.
