[0028] like Figure 1-Figure 4As shown, a filter assembly is arranged below the grinding assembly, and the filter assembly consists of a fixed block 13, a threaded rod 14, an L-shaped plate 15, a first filter plate 16, an adjusting hole 17, a first slot 18, a slide bar 19, an inclined plate 20, a fixed plate 24, a second slot 25 and a spring 26. A fixed block 13 is arranged outside the grinding box 1, and a threaded rod 14 is penetrated inside the fixed block 13. The fixed block 13 is connected to the threaded rod 14 by rotation.

A plurality of inclined plates 20 are arranged in a linear array below the L-shaped plate 15, and the top surfaces of the inclined plates 20 are all inclined surfaces. A first filter plate 16 is arranged on the side of the inclined plate 20, and a spring 26 is fixedly arranged at the other end of the first filter plate 16, and the other end of the spring 26 is fixedly connected to the inner wall of the grinding box 1. Slide bars 19 are fixedly arranged on the front and rear sides of the first filter plate 16, and an adapting slide bar 1 is arranged on the inner wall of the grinding box 1 9, the slide bar 19 is slidably connected to the grinding box 1 through the third slide slot, and the adjacent first filter plates 16 are slidably connected. The top surface of the first filter plate 16 is provided with a symmetrical baffle 27, and the top surface of the first filter plate 16 is linearly arrayed with adjustment holes 17 and first slots 18 that penetrate to the bottom surface. The bottom surface of the first filter plate 16 is slidably connected with a fixed plate 24, and the front and rear sides of the fixed plate 24 are respectively fixedly connected to the inner wall of the grinding box 1, and the discharge pipe is arranged below the fixed plate 24. The top surface of the fixed plate 24 is provided with a second slot 25 that penetrates to the bottom surface. The inner diameters of the first slot 18 and the second slot 25 are the same, and the minimum inner diameter of the adjustment hole 17 increases from top to bottom according to the first filter plate 16, and the minimum inner diameter of the adjustment hole 17 is smaller than the inner diameter of the second slot 25. The filter assembly can adjust the filter hole diameter according to production requirements, thereby filtering color paste raw materials with different particle sizes.

[0029] Specifically, the ground color paste raw material enters the bottom of the fixed plate 24 through the adjustment hole 17 and the second slot hole 25, and is discharged through the discharge pipe. The bottom surface of the first slot hole 18 is blocked by the top surface of the fixed plate 24. When the filter hole aperture of the filter assembly needs to be increased, the threaded rod 14 is rotated to drive the L-shaped plate 15 to move downward. The L-shaped plate 15 moves and contacts the inclined plate 20, which can drive the inclined plate 20 and the first filter plate 16 to move away from the L-shaped plate 15.

[0030] Specific working principle:

[0031] When the utility model is used, the output ends of the first motor 5 and the second motor 10 are respectively controlled to rotate to drive the grinding cone wheel 6 and the active grinding roller 11 to rotate, and the color paste raw material is poured into the feeding groove 8. The grinding cone wheel 6 rotates to cooperate with the grinding disc 7 to perform preliminary grinding on the color paste raw material. The ground color paste raw material passes through the feeding flow channel 9 and the guide plate and enters between the active grinding roller 11 and the driven grinding roller 12. The active grinding roller 11 rotates to cooperate with the driven grinding roller 12 to further grind the color paste raw material. The ground color paste raw material enters the top surface of the first filter plate 16 below the active grinding roller 11 and the driven grinding roller 12. The color paste raw material passes through the adjustment hole 17 and the second slot hole 25 in turn and enters below the fixed plate 24 and is discharged through the discharge pipe. If the color paste needs to be increased When the particle size of the raw material after grinding is small, the output end of the control hydraulic cylinder 3 contracts to drive the lifting rod 4 and the first motor 5 to move upward, and the movement of the first motor 5 drives the grinding cone wheel 6 to move upward, thereby increasing the distance between the grinding cone wheel 6 and the grinding disk 7, and the movement of the lifting rod 4 drives the connecting rod 22 to rotate downward, and the rotation of the connecting rod 22 drives the U-shaped plate 23 to move outward, and the movement of the U-shaped plate 23 drives the driven grinding roller 12 away from the active grinding roller 11, thereby increasing the distance between the active grinding roller 11 and the driven grinding roller 12. By increasing the distance between the grinding cone wheel 6 and the grinding disk 7 and the distance between the active grinding roller 11 and the driven grinding roller 12, the particle size of the color paste raw material after grinding can be increased, so that the color paste raw material can be ground into particles of different particle sizes according to production needs, and it has strong applicability.

[0032] When the filter hole diameter of the filter assembly needs to be increased, the threaded rod 14 is rotated to drive the L-shaped plate 15 to move downward. The L-shaped plate 15 moves and contacts the inclined plate 20, which can drive the inclined plate 20 and the first filter plate 16 to move away from the L-shaped plate 15, and the spring 26 is compressed. When the first filter plate 16 moves to the maximum distance, the first slot 18 of the first filter plate 16 just moves to the top of the second slot 25, and the adjustment hole 17 of the first filter plate 16 is blocked by the first filter plate 16 or the second slot 25 that has not been moved below. As the L-shaped plate 16 moves to the maximum distance, the first slot 18 of the first filter plate 16 just moves to the top of the second slot 25, and the adjustment hole 17 of the first filter plate 16 is blocked by the first filter plate 16 or the second slot 25 that has not been moved below. The first filter plate 16 is moved downwards and moves in sequence in a direction away from the L-shaped plate 15 until the minimum inner diameter of the adjustment hole 17 of the first filter plate 16 is equal to the filter hole diameter. The threaded rod 14 stops rotating, and the ground color paste material enters the lower part of the fixed plate 24 through the first slotted hole 18 after the movement, the adjustment hole 17 that has not been moved, and the second slotted hole 25, so that the filter hole diameter of the filter assembly can be increased. The baffle 27 can limit the color paste material on the top surface of the filter assembly when the filter assembly adjusts the filter hole diameter to prevent the color paste material from scattering to the left and right sides.
