[0032] From the above description, it can be seen that the necking structure is provided to facilitate centralized input into the grinding barrel.

[0033] Furthermore, the first screen and the second screen are both equipped with vibrators.

[0034] It can be seen from the above description that configuring a vibrator can help improve screening efficiency.

[0035] Please refer to Figures 1 to 4 , Embodiment 1 of the present utility model is:

[0036] The utility model provides an automatic coating screening and grinding device, comprising a first grinding barrel 1, a second grinding barrel 2, a third grinding barrel 3, a first screen 4, a second screen 5, a conveyor belt 6 and a collection box 7; the apertures of the first screen 4 and the second screen 5 are equal.

[0037] The first grinding barrel 1, the second grinding barrel 2 and the third grinding barrel 3 are arranged in a direction in sequence and are gradually distributed. The first screen 4 is tilted between the first grinding barrel 1 and the second grinding barrel 2. The higher end of the first screen 4 corresponds to the discharge port below the first grinding barrel 1, and the lower end of the first screen 4 corresponds to the feed port above the second grinding barrel 2. The second screen 5 is tilted between the second grinding barrel 2 and the third grinding barrel 3. The higher end of the second screen 5 corresponds to the discharge port below the second grinding barrel 2, and the lower end of the second screen 5 corresponds to the feed port above the third grinding barrel 3. The lower end of the first screen 4 and the lower end of the second screen 5 are both provided with a shrinking structure 8. The shrinking structure is provided to facilitate centralized feeding into the grinding barrel. The first screen and the second screen are both equipped with a vibrator 9. The vibrator 9 is located at the higher end of the first screen 4 and the higher end of the second screen 5. The configuration of the vibrator helps to improve the screening efficiency.

[0038] The conveyor belt 6 is tilted and is located directly below the first grinding barrel 1, the second grinding barrel 2, the third grinding barrel 3, the first screen 4 and the second screen 5. The collecting box 7 is arranged at the discharge end of the conveyor belt 6. A guard plate is provided on both sides of the conveyor belt 6 to prevent materials from falling out.

[0039] In this embodiment, a first grinding tool 11 is vertically arranged in the first grinding barrel 1, a second grinding tool (not shown in the figure) is vertically arranged in the second grinding barrel 2, and a third grinding tool (not shown in the figure) is vertically arranged in the third grinding barrel 3. The rotation speeds of the first grinding tool, the second grinding tool and the third grinding tool are gradually increased. The first grinding tool, the second grinding tool and the third grinding tool have the same structure and are driven by their respective drive motors.

[0040] Since the rotation speeds of the first grinding tool, the second grinding tool, and the third grinding tool are gradually increased, the final grinding effect can be further ensured. In actual use, the amount entering the third grinding barrel is less than the amount entering the second grinding barrel, which is less than the amount entering the first grinding barrel. Therefore, the volume of the three grinding barrels is gradually reduced from the first grinding barrel, the second grinding barrel, and the third grinding barrel. Because the third grinding barrel is the smallest and has the least paint, a grinding tool with a higher rotation speed can be configured, which is conducive to ensuring the grinding effect. The first grinding barrel is the largest and has the most paint. If the rotation speed of the grinding tool is too fast, it is easy to be damaged due to its greater obstruction, so a grinding tool with a lower rotation speed is configured.

[0041] In summary, the utility model provides an automatic coating screening and grinding device, comprising a first grinding barrel, a second grinding barrel, a third grinding barrel, a first screen, a second screen, a conveyor belt and a collection box; the first grinding barrel, the second grinding barrel and the third grinding barrel are arranged in sequence along a direction and are distributed in a gradually decreasing manner, the first screen is tilted between the first grinding barrel and the second grinding barrel, the higher end of the first screen is arranged corresponding to the discharge port located below the first grinding barrel, the lower end of the first screen is arranged corresponding to the feed port located above the second grinding barrel, the second screen is tilted between the second grinding barrel and the third grinding barrel, the higher end of the second screen is arranged corresponding to the discharge port located below the second grinding barrel, the lower end of the second screen is arranged corresponding to the feed port located above the third grinding barrel, the conveyor belt is simultaneously located directly below the first grinding barrel, the second grinding barrel, the third grinding barrel, the first screen and the second screen, and the collection box is arranged at the discharge end of the transmission belt. The powdered and granular paint is ground through three grinding barrels to ensure the final grinding effect. When the paint after grinding through the first grinding barrel cannot pass through the mesh of the first screen, it will be transferred to the second grinding barrel through the first screen for grinding. If it still cannot pass through the mesh of the second screen, it will be transferred to the third grinding barrel through the second screen for grinding to ensure the final grinding effect. The automatic paint screening and grinding device of the utility model has a simple structure and can achieve the grinding effect.
