10. A metal powder processing method, applicable to the metal powder processing device according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: The user puts metal particles from the top of the screening rack (2), starts the transmission motor (10), and causes the screening mechanism to screen the metal particles. The screened particles are ground into powder by the grinding mechanism, so that the grinding effect is better; S2: The user starts the transmission motor (10), the transmission motor (10) drives the transmission shaft (11) to rotate, the rotation of the transmission shaft (11) drives the disc (12) to rotate, the rotation of the disc (12) drives the round rod (14) to rotate, the rotation of the round rod (14) drives the limiting sleeve (15) to move left and right, the movement of the limiting sleeve (15) drives the support rod (16) and the support frame (17) to move left and right, the left and right movement of the support frame (17) drives the screening frame (2) to move left and right, the movement of the screening frame (2) causes the metal particles to be screened, so that the metal powder and small metal particles fall into the two collecting boxes (5); S3: At the same time, large metal particles fall into the inside of the rolling plate (6), and the left and right movement of the screening frame (2) drives the rolling plate (6) to move left and right, thereby causing the tooth plate (33) to move left and right. The left and right movement of the tooth plate (33) drives the two second gears (32) to rotate, thereby causing the rolling roller (30) to rotate inside the rolling plate (6), so that the rolling roller (30) crushes the large metal particles into small metal particles, and the small metal particles fall into the grinding box (18); S4: The rotation of the transmission shaft (11) drives the first bevel gear (20) and the second bevel gear (21) to rotate. The rotation of the second bevel gear (21) drives the transmission rod (22) and the first sprocket (23) to rotate. The rotation of the first sprocket (23) drives the second sprocket (25) and the first connecting shaft (24) to rotate. The rotation of the first connecting shaft (24) drives the two first gears (29) to rotate. The rotation of the two first gears (29) drives the second connecting shaft (28) to rotate. The rotation of the first connecting shaft (24) and the second connecting shaft (28) drives the two grinding rollers (27) to rotate to grind the small metal particles that fall. When the rolling plate 6 moves left and right, it also drives the two movable rods (34) and the movable shaft (35) to move left and right. The movable shaft ( The soft brush (36) moves left and right to clean the surfaces of the two grinding rollers (27). When the machine is used for a long time and encounters stubborn powder adhering to the surface of the grinding roller (27), the user pulls the knob (41) outward to disengage the buckle (42) from the slot, and rotates the knob (41) to make the scraper (37) contact the grinding roller (27), so that the stubborn powder can be scraped off to achieve a cleaning effect. The design of the first screen (3) and the second screen (4) allows the powder in the metal particles to fall into one of the collection boxes (5), and the second screen (4) filters the smaller metal particles into the other collection box (5). At the same time, the large metal particles fall into the grinding plate for grinding, which makes the grinding efficiency higher.
