[0023] As a preferred embodiment of the above, it further comprises a guide plate 9, which is obliquely installed on the upper left end of the grinding box 1, and is located above the first grinding roller 4;
[0024] By setting the guide plate 9, the raw materials can be directly guided into the grinding area between the first grinding roller 4 and the second grinding roller 5, thereby improving the grinding efficiency.
[0025] As a preferred embodiment of the above, it further comprises two sets of baffle plates 10, which are obliquely installed on the front and rear sides of the top end of the grinding box 1, and the bottom ends of which are located on the front and rear sides of the top ends of the second grinding roller 5 and the third grinding roller 6;
[0026] By setting the baffle plate 10, one of the main functions of the baffle plate 10 is to act as a physical barrier to confine the raw materials in a specific area, so that they can only move along a predetermined path, which helps to evenly distribute the raw materials on the surfaces of the first grinding roller 4, the second grinding roller 5 and the third grinding roller 6, and avoid local overload or idling phenomenon.

[0030] When the raw materials are ground, the first grinding roller 4, the second grinding roller 5 and the third grinding roller 6 will be adhered with the raw materials, which need to be cleaned regularly. By turning on the motor 17, the motor 17 drives the rear screw rod 12 to rotate, and the rear screw rod 12 drives the front screw rod 12 to rotate through the two sets of chain wheels 15 and chains 16. The two screw rods 12 are threadedly connected with the moving plate 13, and the moving plate 13 drives the scraper 14 to move to the right. When the scraper 14 contacts the bottom end of the first grinding roller 4, the rotation of the first grinding roller 4 enables the scraper 14 to clean it. Then the scraper 14 continues to move to the right, and when the scraper 14 contacts the bottom end of the second grinding roller 5, the rotation of the second grinding roller 5 enables the scraper 14 to clean it. Then the scraper 14 continues to move to the right, and when the scraper 14 contacts the bottom end of the third grinding roller 6, the rotation of the third grinding roller 6 enables the scraper 14 to clean it.

[0035] As a preferred embodiment of the above, the first grinding roller 4, the second grinding roller 5 and the third grinding roller 6 are made of chilled cast iron.
[0036] Chilled cast iron is one of the most commonly used drum materials, which has good wear resistance and hardness and relatively low cost. After special treatment, the surface of chilled cast iron is very hard, which is suitable for most conventional grinding tasks.
[0037] This utility model discloses a raw material grinding device for alkyd topcoat production. During operation, firstly, according to the grinding requirements of the raw material, four sets of electric screws 8 are activated. These four sets of electric screws 8 are threadedly connected to four sets of sliders 7, which in turn drive the second grinding roller 5 and the third grinding roller 6 to move, thereby adjusting the distance between the first grinding roller 4, the second grinding roller 5, and the third grinding roller 6. After adjustment, the raw material is introduced into the grinding chamber 1 through the feed hopper 3. The first grinding roller 4 and the second grinding roller 5 perform coarse grinding on the raw material. Then, the raw material is fed between the second grinding roller 5 and the third grinding roller 6, where it performs fine grinding. The ground raw material is discharged through the outlet of the grinding chamber 1. After grinding, raw material adheres to the first grinding roller 4, the second grinding roller 5, and the third grinding roller 6, requiring further processing. Regular cleaning is performed by turning on the motor 17, which drives the rear screw 12 to rotate. The rear screw 12 then drives the front screw 12 to rotate via two sets of sprockets 15 and a chain 16. The two sets of screws 12 are threadedly connected to the moving plate 13. The moving plate 13 drives the scraper 14 to move to the right. When the scraper 14 contacts the bottom end of the first grinding roller 4, the first grinding roller 4 rotates, causing the scraper 14 to clean it. The scraper 14 continues to move to the right until it contacts the bottom end of the second grinding roller 5, which rotates, causing the scraper 14 to clean it. The scraper 14 continues to move to the right until it contacts the bottom end of the third grinding roller 6, which rotates, causing the scraper 14 to clean it. This process cleans the first grinding roller 4, the second grinding roller 5, and the third grinding roller 6.
[0038] The raw material grinding equipment for alkyd topcoat production of this utility model has common mechanical installation, connection and setting methods, and can be implemented as long as it can achieve its beneficial effect. The electric screw 8, motor 17 and controller 19 of the raw material grinding equipment for alkyd topcoat production of this utility model are purchased from the market. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual.
[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
