[0025] Working principle: When the metal foreign body detection and removal device for powder coating production is used, the powder coating is first transported from one side to the other side through the belt conveyor mechanism 2. When the powder coating passes the bottom of the rotating shaft 15, the adsorption magnet 14 on the outer wall of the rotating shaft 15 adsorbs the metal foreign bodies in the powder coating. When the metal foreign bodies on the rotating shaft 15 are almost adsorbed, the second motor 116 is started, and the second motor 116 drives the rotating shaft 15 to rotate counterclockwise. During the rotation of the rotating shaft 15, the metal foreign bodies on the outer wall of the rotating shaft 15 approach the opening on one side of the filter box 17, and the metal foreign bodies on the outer wall of the rotating shaft 15 are attracted to the opening on one side of the filter box 17.

Then the electromagnet 113 is closed, and the metal foreign matter on the electromagnet 113 falls onto the filter screen 19. At this time, the filter screen 19 automatically vibrates under the drive of the vibration motor 112, so that the powder coating on the metal foreign matter is quickly separated from the metal foreign matter, and the powder coating is collected at the bottom of the filter box 17.
