[0024] like Figures 1 to 5As shown, the present invention discloses a preparation device for road marking paint, comprising a processing box 1, a material bucket 2, four sets of support columns 3, two sets of screening plates 5, a rotating device, a grinding device, and a discharge device. The processing box 1 is provided with four sets of support legs 27 at the bottom. The grinding device is installed inside the processing box 1. A turntable 7 is rotatably provided at the top of the processing box 1. The material bucket 2 is installed on the left side of the top of the turntable 7 through the four sets of support columns 3. The top of the material bucket 2 is connected to a feed inlet 4. Two sets of screening plates 5 are installed inside the material bucket 2. The discharge device is installed on the lower left side of the material bucket 2. The bottom of the material bucket 2 is connected to a discharge pipe 6. The output end of the discharge pipe 6 is connected to the turntable 7. The discharge pipe 6 is connected to the grinding device. The rotating device is installed at the top of the processing box 1 and is connected to the turntable 7.
[0025] Raw materials are fed into the material bucket 2 through the feed inlet 4. Two sets of screening plates 5 screen the raw materials. The screened raw materials are then fed into the grinding device through the discharge pipe 6. At the same time, the rotating device is turned on, which drives the turntable 7 to rotate, so that the raw materials are evenly fed into the grinding device. The grinding device then grinds the raw materials. By setting up this equipment, larger particles in the raw materials can be screened, reducing the grinding load and improving its working efficiency. Moreover, the rotating device can feed the raw materials into the grinding device, thereby improving its grinding effect.

[0027] By setting up a gear ring 8, a gear 9, and a first motor 10, turning on the first motor 10 causes the gear 9 to mesh with the gear ring 8, which in turn causes the turntable 7 to rotate as a whole. This results in the raw materials discharged from the discharge pipe 6 being evenly distributed in the grinding device, thereby improving the grinding effect on the raw materials.
[0028] As a preferred embodiment of the above, the grinding device includes a grinding barrel 11, a second motor 12, a rotating shaft 13, multiple sets of grinding hammers 14, a fine grinding device, and a filter assembly.

When the second motor 12 is turned on, it drives multiple sets of grinding hammers 14 on the rotating shaft 13 to rotate. The multiple sets of grinding hammers 14 then hammer and grind the raw materials in the grinding barrel 11. The raw materials that meet the grinding standards are then introduced into the fine grinding device through the filter assembly for fine grinding. This can effectively grind the raw materials and improve their grinding effect.
[0030] As a preferred embodiment of the above, the fine grinding device includes a fixed grinding barrel 15, a movable grinding disc 16, a discharge valve 18, a drive shaft 19, a mounting plate 20, two sets of bevel gears 21, and a third motor 22.

The third motor 22 is turned on, and the third motor 22 drives the moving grinding disc 16 to rotate through the drive shaft 19 via two sets of bevel gears 21. The moving grinding disc 16 and the fixed grinding barrel 15 work together to finely grind the raw materials. The finely ground raw materials are then discharged through the discharge pipe 17 by opening the discharge valve 18, which further finely grinds the raw materials and improves the grinding effect.
[0032] As a preferred embodiment of the above, the filter assembly is configured as a filter plate 23, which is installed in the lower part of the grinding barrel 11.
[0033] By setting up a filter plate 23, the raw materials that meet the grinding standards are filtered through the filter plate 23 and then introduced between the fixed grinding barrel 15 and the moving grinding disc 16, which can control the particle size of the raw materials after the initial grinding.

[0038] As a preferred embodiment of the above embodiment, the two sets of screening plates 5 are installed alternately and inclined inside the material barrel 2;
[0039] It facilitates the automatic screening of raw materials by gravity.
[0040] This utility model discloses a preparation device for road marking paint. During operation, raw materials are first introduced into the material barrel 2 through the feed inlet 4. Two sets of screening plates 5 then screen the raw materials. The screened raw materials are then introduced into the grinding barrel 11 through the discharge pipe 6. Simultaneously, the first motor 10 is turned on, driving the gear 9 to mesh with the gear ring 8. The gear ring 8 drives the turntable 7 to rotate, thus evenly distributing the raw materials discharged through the discharge pipe 6 into the grinding barrel 11. The second motor 12 is then turned on, driving the turntable... Multiple grinding hammers 14 on shaft 13 rotate, and the grinding hammers 14 hammer and grind the raw materials in grinding barrel 11.
