AI Technical Summary
Existing horizontal grinding mills for coatings use a single-stage grinding method, which cannot fully refine the particles in the coating. In particular, when the coating contains particles of various sizes, it is difficult to achieve the ideal particle size distribution, resulting in poor grinding effect.
A multi-stage grinding method is adopted, which forms a closed-loop processing flow through the high-speed rotation of the conical grinding cylinder and the rotation of the shovel plate to realize the multi-stage grinding of the coating, including crushing, preliminary grinding, primary refinement, re-grinding and re-refinement. High-speed airflow is used to re-enter the conical outer cylinder for secondary grinding until the fineness requirement is met.
This process achieves gradual refinement of coating particles, improves grinding effect and quality, and ensures a more uniform and delicate particle size distribution in the coating.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating grinding technology, specifically a horizontal coating grinding machine with multi-stage grinding. Background Technology
[0002] Paint is a material applied to the surface of an object to be protected or decorated. During the processing of paint, it is often necessary to grind it. Grinding the paint can make the pigment particles smaller and more evenly dispersed, which helps to improve the hiding power and coloring power of subsequent paints.
[0003] A Chinese patent with publication number CN216459204U discloses a horizontal sand mill for coatings, including a working box. A motor is fixedly connected to the right side of the working box, and the output end of the motor passes through the side wall of the working box and is fixedly connected to a central shaft. This invention, through the coordinated arrangement of the motor, central shaft, and first gear, can drive a second gear to rotate. The second gear drives a fan to rotate via a crossbar, and the fan rotation can accelerate the airflow speed in the working box. Through the coordinated arrangement of the driving wheel, driven wheel, and rotating rod, a scraper can be driven to rotate. The scraper flips the coating accumulated on the filter screen, thereby performing multiple sanding operations on the coating, increasing the sanding effect, and preventing coating accumulation on the filter screen from reducing the filtration speed of impurities, thus improving the filtration efficiency.
[0004] The aforementioned horizontal coating grinding mill uses a single-stage grinding method, which cannot fully grind and refine the particles in the coating. In particular, when the coating contains particles of various sizes, single-stage grinding often fails to achieve the ideal particle size distribution, resulting in poor grinding effect on the coating particles. Therefore, a multi-stage grinding horizontal coating grinding mill is proposed to address the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a horizontal coating grinding machine with multi-stage grinding.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A horizontal coating grinding machine with multi-stage grinding, comprising a base, a first support seat and a second support seat fixedly connected to the base, a conical outer cylinder fixedly connected to the first support seat, a fixed plate fixedly connected to the side wall of the second support seat, a processing cylinder connected between the fixed plate and the conical outer cylinder, a crushing cylinder connected to the other end of the conical outer cylinder, a first motor mounted on the outer wall of the fixed plate, a rotating disk mounted on the output end of the first motor, and the rotating disk disposed inside the processing cylinder, a conical grinding cylinder fixed on the rotating disk, and the conical grinding cylinder disposed inside the conical outer cylinder, multiple grinding teeth fixed on the outer surface of the conical grinding cylinder, a grinding disc fixed on the circumferential surface of one end of the conical grinding cylinder near the processing cylinder, and multiple protrusions fixed on the inner circumferential surface of the conical grinding cylinder, for grinding coatings... During grinding, the crushed paint particles flow into the conical outer cylinder. The first motor is started, causing the rotating disc to drive the shovel and the conical grinding cylinder to rotate. The high-speed rotation of the conical grinding cylinder grinds the crushed paint particles. The ground particles flow into the processing cylinder through the guide port. Paint particles that meet the fineness requirements fall into the collection box through the filter holes. Larger paint particles that do not meet the fineness requirements accumulate in the processing cylinder. At this time, the rotating disc drives the shovel to rotate, which can scrape up the larger paint particles at the bottom of the processing cylinder. The shovel transports the retained particles to the fan area, where a high-speed airflow blows them into the return pipe and back into the conical outer cylinder for secondary grinding, forming a closed-loop processing process. This repeated operation enables multi-stage grinding of the paint. Through multiple grinding processes, the paint raw materials can be gradually refined, making the grinding more thorough and precise, and improving the grinding effect and quality.
[0007] Preferably, multiple shovels are fixed on the circumferential surface of the rotating disk, and the fixed disk has mounting holes in which a fan is installed. A return pipe is connected between the processing cylinder and the conical outer cylinder. When grinding the coating, the rotating disk drives the shovels to rotate, which can scrape off larger particles of coating from the bottom of the processing cylinder. The shovels transport the retained particles to the fan area, where a high-speed airflow blows them into the return pipe and back into the conical outer cylinder for secondary grinding.
[0008] Preferably, the bottom of the conical outer cylinder is provided with a guide port, and the bottom of the circular surface of the processing cylinder is provided with multiple filter holes. A collection box is provided below the filter holes. When grinding the coating, by setting the filter holes, the coating that meets the fineness requirements can fall into the collection box through the filter holes, and the larger particles of coating that do not meet the fineness requirements are intercepted.
[0009] Preferably, a second motor is installed on the first support base, and a rotating rod is connected to the output end of the second motor. A crushing wheel is fixed to the end of the rotating rod, and the crushing wheel is set inside the crushing cylinder. Multiple crushing blades are fixed on the outer surface of the crushing wheel, and a feed hopper is connected to the top of the circumferential surface of the crushing cylinder. When crushing the coating, the second motor is started, causing the rotating rod to drive the crushing wheel and the crushing blades on it to rotate, thereby crushing the coating and reducing the subsequent grinding time of the coating particles.
[0010] The advantages of this utility model are:
[0011] In this invention, when grinding coatings, the second motor is first started to crush the coatings using a crushing wheel. The crushed coating particles flow into a conical outer cylinder. Then, the first motor is started, causing a rotating disc to drive a shovel and a conical grinding cylinder to rotate. The high-speed rotation of the conical grinding cylinder grinds the crushed coating particles. The ground particles flow into the processing cylinder through a guide port. Coatings that meet the fineness requirements fall into a collection box through filter holes. Larger particles that do not meet the fineness requirements accumulate in the processing cylinder. At this point, the rotating disc drives the shovel to rotate, which scrapes the larger particles from the bottom of the processing cylinder. The shovel transports the retained particles to the fan area, where a high-speed airflow blows them into the return pipe, where they re-enter the conical outer cylinder for secondary grinding, forming a closed-loop processing flow. This repeated operation enables multi-stage grinding of the coatings. Through multiple grinding processes, the coating raw materials can be gradually refined, resulting in more thorough and precise grinding, and improving the grinding effect and quality.

Through the high-speed rotation of the conical grinding cylinder 10, the crushed paint particles can be ground. The ground particles flow into the processing cylinder 6 through the guide port 15. Paint that meets the fineness requirements will fall into the collection box 17 through the filter hole 16. Larger paint particles that do not meet the fineness requirements will accumulate in the processing cylinder 6. At this time, the rotating disk 9 drives the shovel plate 13 to rotate, which can scrape the larger paint particles at the bottom of the processing cylinder 6.

[0022] Please see Figure 2As shown, a second motor 20 is installed on the first support base 2. The output end of the second motor 20 is connected to a rotating rod 21. A crushing wheel 22 is fixed to the end of the rotating rod 21 and is located inside the crushing cylinder 7. Multiple crushing blades are fixed on the outer surface of the crushing wheel 22. A feed hopper 23 is connected to the top of the circumferential surface of the crushing cylinder 7. During operation, when crushing the coating, the coating material to be processed is first fed into the crushing cylinder 7 through the feed hopper 23.

[0023] Working Principle: The aforementioned horizontal coating grinding mill uses a single-stage grinding method, which cannot adequately grind and refine the particles in the coating. Especially when the coating contains particles of various sizes, single-stage grinding often fails to achieve the ideal particle size distribution, resulting in poor grinding performance. Therefore, to address this problem, a multi-stage horizontal coating grinding mill is proposed. When grinding the coating, the raw material to be processed is first fed into the crushing cylinder 7 through the feed hopper 23. Then, the second motor 20 is started, causing the rotating rod 21 to drive the crushing wheel 22 and its crushing blades to rotate, thereby crushing the coating. The crushed coating particles flow into the conical outer cylinder 4. The first motor 8 is then started, causing the rotating disk 9 to drive the shovel plate 13 and the conical grinding cylinder 10 to rotate. Through the conical grinding... The high-speed rotation of the grinding cylinder 10 grinds the crushed paint particles. The ground particles flow into the processing cylinder 6 through the guide port 15. Paint particles that meet the fineness requirements fall into the collection box 17 through the filter holes 16. Larger paint particles that do not meet the fineness requirements accumulate in the processing cylinder 6. At this time, the rotation of the rotating disk 9 drives the shovel plate 13 to scrape up the larger paint particles at the bottom of the processing cylinder 6. The shovel plate 13 transports the retained particles to the area of the blower 19. The high-speed airflow blows them into the return pipe 18 and re-enters the conical outer cylinder 4 for secondary grinding, forming a closed-loop processing process. This repeated operation enables multi-stage grinding of the paint. Through multiple grinding processes, the paint raw materials can be gradually refined, making the grinding more thorough and precise, and improving the grinding effect and quality.
