[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-5 An embodiment of this utility model provides a high-efficiency pigment grinding machine, including a grinding box body 8. A grinding mechanism 15 is installed inside the grinding box body 8. One end of the grinding mechanism 15 is connected to a driven wheel 9 through a transmission shaft 10. A bearing assembly 14 is installed on one side of the driven wheel 9. The bearing assembly 14 is wrapped around the outer surface of the transmission shaft 10. The bottom of the bearing assembly 14 is fixedly connected to a support frame 11 set on the outer surface of the grinding box body 8 through a bearing seat 16. Grinding blades 17 are provided on the grinding mechanism 15. An abrasive gap 18 is provided between the grinding blades 17. The outer surface of the grinding blades 17 is respectively provided with a wear-resistant coating 19 and a rust-proof coating 20.

[0023] Furthermore, a fixed frame 4 is installed below the grinding box body 8, and a discharge box 7 is installed at the bottom of the grinding box body 8. A discharge trough 13 is provided at one end of the discharge box 7 to facilitate the safe discharge and collection of the fully ground pigment raw material from the discharge trough 13.

[0024] Furthermore, a feeding screen 1 is installed at the upper end of the grinding box body 8, and a feeding trough 12 is provided inside the feeding screen 1 to facilitate the feeding of the pigment raw material to be ground from the feeding screen 1 into the grinding box body 8.

[0025] Furthermore, a drive motor 3 is installed on the fixed frame 4, and a shock-absorbing support 5 is installed at the bottom of the drive motor 3. The output end of the drive motor 3 is connected to the drive wheel 2 through a rotating shaft. The drive wheel 2 is connected to the driven wheel 9 through a belt assembly 6. By turning on the drive motor 3, the drive wheel 2 can be driven to drive the driven wheel 9 to perform transmission, which in turn can drive the grinding mechanism 15 to rotate at high speed. Through the high-speed rotating grinding blade 17 and the abrasive gap 18, the pigment raw material put into the grinding box can be pre-cut and ground. During the high-speed operation of the abrasive gap 18, the surface of the pigment raw material can be pre-crushed and destroyed. The blade structure in the gap is used to squeeze and grind the pigment raw material, which achieves a good grinding and pulverizing effect.

[0026] Furthermore, the wear-resistant coating 19 is applied to the outer surface of the anti-rust coating 20. The wear-resistant coating 19 and the anti-rust coating 20 can provide good safety protection for the surface of the grinding mechanism 15 when it is running at high speed, so as to avoid rust and wear on the surface of the grinding mechanism 15 and further improve the service life of the grinding mechanism 15.

[0027] Furthermore, a raised crushing structure 21 is installed between the grinding blades 17, which can further quickly and efficiently cut and grind the pigment raw materials put into the grinding box, achieving a good crushing effect.

[0028] Working Principle: During use, a feeding screen 1 is installed at the upper end of the grinding box body 8. The feeding screen 1 has a feeding trough 12 inside. The pigment raw material to be processed is poured from the feeding screen 1 into the grinding box body 8. A grinding mechanism 15 is installed inside the grinding box body 8. The drive motor 3 drives the drive wheel 2 to rotate rapidly, thereby driving the grinding mechanism 15 to operate at high speed. Grinding blades 17 are installed on the grinding mechanism 15, with abrasive gaps 18 between the blades. Through the rapidly rotating grinding blades 17 and the abrasive gaps 18, the pigment raw material fed into the grinding box can be pre-cut and ground. During the rapid operation, the abrasive gaps 18 can pre-cut and grind the surface of the pigment raw material. The grinding mechanism uses a blade structure within the gaps to squeeze and grind the pigment raw material, achieving a good grinding and pulverizing effect. A raised crushing structure 21 is installed between the grinding blades 17, which can further quickly and efficiently cut and grind the pigment raw material fed into the grinding chamber, achieving a good crushing effect. The outer surface of the grinding blades 17 is respectively provided with a wear-resistant coating 19 and a rust-proof coating 20. The wear-resistant coating 19 and the rust-proof coating 20 can provide good safety protection for the surface of the grinding mechanism 15 when it operates at high speed, preventing rust and wear on the surface of the grinding mechanism 15, and further improving the service life of the grinding mechanism 15. Finally, the ground pigment raw material particles fall from the discharge trough 13 and are collected.
