Specifically, the top cover 12 is detachably connected to the top of the tank body 1, either by threaded connection or snap-fit, preferably by threaded connection. Furthermore, the bottom of the tank body 1 has support feet 13 to support the entire grinding machine; at least three support feet 13 are provided, preferably three or four, to improve stability. The top cover 12 also has a handle 14, allowing for easy removal of the top cover 12 when cleaning or maintenance is required.

[0044] Grinding assembly 2 is disposed inside tank 1. Grinding assembly 2 includes a feeding pipe 21 and a grinding mechanism 22. One end of the feeding pipe 21 is connected to one end of the grinding mechanism 22, and the other end of the feeding pipe 21 extends upward through and out of tank 1. Cooling assembly 3 is disposed on grinding mechanism 22 and is used to cool the pigment paste produced during grinding. Pigment paste raw material is added into grinding mechanism 22 through feeding pipe 21. Grinding mechanism 22 grinds pigment paste raw material. During the grinding process, cooling assembly 3 cools pigment paste, neutralizes the heat generated during grinding, thereby reducing the temperature of pigment paste and preventing pigment paste deterioration due to excessive temperature, thus improving the quality of pigment paste.

[0045] Please refer to Figure 2 and Figure 3The grinding mechanism 22 includes a grinding tank 221, a lower grinding disc 222, an upper grinding disc 223, and a drive mechanism 224. The grinding tank 221 is located inside the tank body 1, and a liquid outlet 2211 is provided on the side of the grinding tank 221. The lower grinding disc 222 is rotatably connected to the grinding tank 221, and the upper grinding disc 223 is disposed on the lower grinding disc 222. A through hole is provided on the upper grinding disc 223, and one end of the feeding pipe 21 communicates with the through hole. The drive mechanism 224 is connected to the lower grinding disc 222 for driving the lower grinding disc 222 to rotate. In practice, the pigment raw material is added through the feeding pipe 21 between the upper grinding disc 223 and the lower grinding disc 222. The drive mechanism 224 drives the lower grinding disc 222 to rotate, thereby grinding the pigment raw material. During the grinding process, the pigment produced is thrown out from the lower grinding disc 222 under the action of centrifugal force, and then enters the grinding tank 221. Finally, the pigment flows out from the liquid outlet 2211 to the bottom of the inner cavity of the tank 1, and finally flows out from the discharge port 11. Preferably, the surface of the grinding tank 221 is an inclined surface sloping towards the liquid outlet 2211, so that the pigment can flow out of the grinding tank 221 more quickly.

[0046] Please continue to refer to Figure 2 and Figure 3 The drive mechanism 224 includes a drive unit 2241 and a transmission unit 2242. The drive unit 2241 is located on the outside of the tank body 1. One end of the transmission unit 2242 is connected to the output end of the drive unit 2241, and the other end is connected to the lower grinding disc 222. Positioning the drive unit 2241 outside the tank body 1 prevents moisture in the pigment paste from adversely affecting the drive unit 2241, thus avoiding reduced efficiency or damage, and further extending its service life.

[0047] Preferably, the drive unit 2241 includes a mounting plate 22411, a drive motor 22412, and a reducer 22413. The mounting plate 22411 is disposed on the outside of the tank body 1, the drive motor 22412 is mounted on the mounting plate 22411, and the reducer 22413 is mounted on the mounting plate 22411 and is drive-connected to the drive motor 22412. The reducer 22413 is also drive-connected to the transmission unit 2242. In this embodiment, the lower grinding disc 222 is indirectly driven to rotate by the cooperation of the drive motor 22412 and the reducer 22413 to grind the pigment raw material. The principle is simple and easy to implement.

[0048] In this embodiment, the transmission unit 2242 includes a transmission shaft 22421, a transmission gear 22422, a driven gear 22423, and an output shaft 22424. One end of the transmission shaft 22421 is connected to the output end of the reducer 22413. The transmission gear 22422 is located at the other end of the transmission shaft 22421, and the driven gear 22423 meshes with the transmission gear 22422. One end of the output shaft 22424 is connected to the driven gear 22423, and the other end is connected to the lower grinding disc 222. In this embodiment, the lower grinding disc 222 rotates via gear transmission. Furthermore, transmission can also be achieved using common methods in the prior art, such as a combination of pulleys and belts or a combination of gears and sprockets.

[0049] Preferably, a plurality of connecting blocks 2212 are provided on the side of the grinding groove 221, and the grinding groove 221 is fixed to the inside of the tank body 1 by the plurality of connecting blocks 2212. Three connecting blocks 2212 are provided, and the three connecting blocks 2212 are evenly distributed along the circumference of the grinding groove 221.

[0050] Furthermore, a connecting rod 2213 is provided at the bottom of the grinding groove 221. A bearing 2214 is provided at the end of the connecting rod 2213 away from the grinding groove 221. The other end of the drive shaft 22421 passes through the bearing 2214 and is connected to the drive gear 22422. The connecting rod 2213 provides support for the drive shaft 22421, improving the stability of the transmission of the lower grinding disc 222.

[0051] In this embodiment, the cooling assembly 3 includes a cooling water channel 31, an inlet pipe 32, and an outlet pipe 33. The cooling water channel 31 is coiled in a mosquito coil shape within the upper grinding disc 223, and has an inlet and an outlet, both connected to a through hole. One end of the inlet pipe 32 is connected to the inlet, and the other end extends from the feed pipe 21 and connects to an external water circulation device. One end of the outlet pipe 33 is connected to the outlet, and the other end extends from the feed pipe 21 and connects to the water circulation device. The mosquito coil shape of the cooling water channel 31 allows for better heat exchange and improves heat exchange efficiency. The external circulation device can be connected via a pump. Separate cold water tanks and hot water tanks are provided. Water from the cold water tank is pumped into the inlet pipe 32, and after heat exchange, it enters the hot water tank from the outlet pipe 33 or is used as a heat source for other equipment. Water in the hot water tank is cooled and then enters the cold water tank.

[0052] In summary, the grinding mill for pigment production in this embodiment has a cooling component 3 in the grinding mechanism 22 to cool the pigment produced during the grinding process, neutralize the heat generated during the grinding process, thereby reducing the temperature of the pigment and preventing the pigment from deteriorating due to excessively high temperature, thus improving the quality of the pigment.
