[0023] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The function of the accompanying drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be construed as a limitation on the protection scope of the present utility model.

[0024] Refer to Figures 1-4 , a secondary fine grinding device for fine processing of coatings, including a fine grinding tank 1. A fine grinding unit 2 is arranged inside the fine grinding tank 1. A feed pipe 3 is fixedly connected to the upper side of the fine grinding tank 1. The feed pipe 3 is convenient for putting the coating into the fine grinding tank 1 and performing fine grinding operations on the coating through the fine grinding unit 2.

[0025] The fine grinding unit 2 includes a rotating shaft 202, which is rotatably connected to the top inside the fine grinding tank 1. The inside of the fine grinding tank 1 is fixedly connected with a fixing frame 203. The upper side of the fixing frame 203 is provided with a plurality of filter frames 205. The inside of the fixing frame 203 is fixedly connected with a partition plate 204. The outside of the rotating shaft 202 and above the partition plate 204 is fixedly connected with a first fixing plate 206. The lower side of the first fixing plate 206 is fixedly connected with two bottom blocks 207. A grinding roller 208 is rotatably connected between the two bottom blocks 207. The lower side of the fixing frame 203 is fixedly connected with an inner tank 209. The outside of the rotating shaft 202 and below the partition plate 204 is provided with a moving ring 214. The lower side of the moving ring 214 is fixedly connected with a fixing rod 210. The lower side of the fixing rod 210 is fixedly connected with a fine grinding disc 211. The outside of the fine grinding disc 211 is fixedly connected with a plurality of crushing knives 212. The lower side of the inner tank 209 is fixedly connected with a discharge pipe 4. The moving ring 214 is slidably connected with the rotating shaft 202. The upper side of the fine grinding tank 1 is fixedly connected with a first motor 201. The output end of the first motor 201 is fixedly connected with the upper end of the rotating shaft 202. A valve is arranged outside the discharge pipe 4. The valve facilitates the discharge of the coating through the discharge pipe 4. When in use, the first motor 201 is started, and the first motor 201 drives the rotating shaft 202 to rotate. The rotating shaft 202 is rotatably connected with the partition plate 204. The rotating shaft 202 drives the first fixing plate 206 to rotate. The first fixing plate 206 drives the grinding roller 208 on the bottom blocks 207 to rotate, so that the coating falling on the partition plate 204 is preliminarily ground by the grinding roller 208. The ground coating is squeezed to the side. When passing through the filter screen on the filter frame 205, the relatively fine fixed coating particles are filtered to the lower side, and the coating with large particles stays on the upper side and continues to be ground by the grinding roller 208. The falling coating drops into the inner tank 209. At the same time, when the rotating shaft 202 drives the moving ring 214 to rotate, the moving ring 214 drives the fixing rod 210 to rotate, and the fixing rod 210 drives the fine grinding disc 211 to rotate. The fine grinding disc 211 grinds the coating again to increase the fineness of the coating. At the same time, the fine grinding disc 211 drives the crushing knives 212 to rotate, so that the crushing knives 212 cut the fixed particles of the coating to enhance the fine grinding effect.

[0026] On the outer side of the rotating shaft 202, above the moving ring 214, there is a second fixing plate 220 fixedly connected. On the rear side of the second fixing plate 220, there is a fixing block 218 fixedly connected. On the rear side of the fixing block 218, there is a second motor 219 fixedly connected. The output end of the second motor 219 is fixedly connected with a cam 217. There is also a connecting plate 216 rotatably connected to the outer side of the cam 217. The outer side of the lower end of the connecting plate 216 is rotatably connected with a connecting block 215. The connecting block 215 is fixedly connected with the moving ring 214. The connecting plate 216 is arranged in an inclined structure. During the fine grinding process, the second motor 219 is started. The second motor 219 drives the cam 217 to rotate. The cam 217 drives the connecting plate 216 to rotate. The connecting plate 216 drives the moving ring 214 on the connecting block 215 to move up and down repeatedly. The moving ring 214 drives the fine grinding disc 211 on the fixing rod 210 to move up and down repeatedly, facilitating the fine grinding disc 211 to extrude the fixed particles and enhancing the fine grinding effect.

[0027] On the upper side of the fine grinding disc 211, there is a tapered block 213 fixedly connected. The tapered block 213 facilitates the concentration of the coating towards the side, facilitating the coating to fall to the bottom of the inner tank 209 and facilitating the subsequent fine grinding.

[0028] Working principle: When in use, first, the coating is introduced into the fine grinding tank 1 through the feed pipe 3. Then, the first motor 201 is started to drive the rotating shaft 202 to rotate. The rotating shaft 202 drives the grinding roller 208 to rotate, enabling the grinding roller 208 to conduct preliminary grinding on the coating. Then, the coating is filtered through the filter frame 205. The filtered coating falls into the inner tank 209. The rotating shaft 202 drives the fine grinding disc 211 to rotate to grind the coating again, enhancing the grinding effect. The second motor 219 is started to drive the cam 217 to rotate. Under the action of the connecting plate 216, the moving ring 214, and the fixing rod 210, it is convenient to control the fine grinding disc 211 to move up and down repeatedly, facilitating the fine grinding disc 211 to extrude the coating and enhancing the fine grinding effect. Then, the coating is discharged through the discharge pipe 4.

[0029] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art to which it pertains, various changes can also be made without departing from the purpose of the present invention.
