At the same time, when it is necessary to clean the raw materials attached to the surface of the grinding roller 103, the two electric push rods 109 can be turned on. The two electric push rods 109 drive the first scraper 110 to approach the grinding roller 103 until the first scraper 110 contacts the grinding roller 103. At this time, the grinding roller 103 is rotated, and the first scraper 110 can scrape the raw materials on the surface of the grinding roller 103, thereby reducing the waste of raw materials.

[0026] Example 2, as Figure 1-Figure 5 As shown, the outer wall of the grinding box 101 is provided with a square groove 104, and the inner wall of the square groove 104 is movably inserted with a filter screen 105. A support block 106 is fixedly mounted on one end of the outer wall of the filter screen 105, and a handle 107 is fixedly mounted on one end of the outer wall of the support block 106. Two vibration motors 108 are fixedly mounted on the outer wall of the grinding box 101. A top plate 115 is fixedly mounted on the top of the grinding box 101, and a discharge port 111 is provided at the bottom end of the grinding box 101. A discharge valve 112 is provided at the bottom end of the discharge port 111. Two support plates 113 are fixedly mounted on the outer wall of the grinding box 101, and two support rods 114 are fixedly mounted on the bottom ends of the two support plates 113.

A feed port 203 is provided at the top of the pulverizing drum 201. The pulverizing drum 201 is fixedly inserted into the outer wall of the top plate 115.

[0027] The effect achieved by the entire embodiment 2 is that the raw materials ground by the grinding roller 103 will fall on the filter screen 105. The filter screen 105 will screen some raw materials with larger particles that do not meet the grinding standards, so that the raw materials that meet the standards fall from the filter screen 105. In order to increase the filtration speed of the filter screen 105, the two vibration motors 108 can be turned on. The two vibration motors 108 vibrate the powder raw materials on the filter screen 105. The vibration can help separate the larger particles and impurities in the powder faster, thereby improving the filtration speed and quality. When the filter screen 105 needs to be cleaned, the handle 107 can be pulled to pull the filter screen 105 out of the grinding box 101 for cleaning.

[0028] Working principle: When the paint raw materials need to be crushed, the raw materials are first poured into the crushing barrel 201 through the feed port 203, and then the second motor 202 is turned on. The second motor 202 drives the rotating rod 204 to rotate, and the rotating rod 204 drives the breaking rod 205 to rotate, thereby breaking some large pieces of raw materials into small pieces of raw materials. During the rotation process, the rotating rod 204 drives the second scraper 207 to rotate on the inner wall of the crushing barrel 201 through the connecting rod 206, thereby preventing the raw materials from adhering to the inner wall of the crushing barrel 201. When the raw materials in the crushing barrel 201 are crushed, the two first motors 102 are turned on, and the two first motors 102 drive the two grinding rollers 103 to rotate. At this time, the discharge solenoid valve 209 is opened, so that the raw materials in the crushing barrel 201 fall from the discharge pipe 208. At this time, the grinding roller 103 will grind the raw materials, thereby improving the grinding effect of the paint raw materials. The raw materials ground by the grinding roller 103 will fall on the filter plate 105. The filter plate 105 Some raw materials with larger particles that do not meet the grinding standards will be screened, so that the raw materials that meet the standards fall from the filter plate 105. In order to increase the filtration speed of the filter plate 105, the two vibration motors 108 can be turned on. The two vibration motors 108 vibrate the powder raw materials on the filter plate 105. The vibration can help separate larger particles and impurities in the powder more quickly, thereby improving the filtration speed and quality. When the filter plate 105 needs to be cleaned, the handle 107 can be pulled to pull the filter plate 105 out of the grinding box 101 for cleaning. When the raw materials attached to the surface of the grinding roller 103 need to be cleaned, the two electric push rods 109 can be turned on. The two electric push rods 109 drive the first scraper 110 to approach the grinding roller 103 until the first scraper 110 contacts the grinding roller 103. At this time, the grinding roller 103 is rotated, and the first scraper 110 can scrape the raw materials on the surface of the grinding roller 103, thereby reducing the waste of raw materials.
