This utility model belongs to the field of additive
manufacturing technology and discloses a cleaning device for additive manufacturing
metal powder screens. It includes an ultrasonic cleaner, with a
drive motor fixedly connected to the back of the ultrasonic cleaner. A rotating shaft is fixedly sleeved at the other end of the output shaft of the
drive motor. A rotating rod is fixedly sleeved on the outer surface of the rotating shaft, and a round shaft is fixedly sleeved inside the other end of the rotating rod. A crossbar is movably connected to the outer surface of the round shaft. This utility model, by setting up a
drive motor, round shaft, crossbar, connecting plate, and
brush plate, allows the drive motor to rotate, causing the rotating shaft to drive the rotating rod to rotate. This, in turn, causes the round shaft to rotate, pressing the crossbar and moving it forward. This, in turn, causes the two connecting plates to move the
brush plate forward, brushing the bottom of the screen, thus achieving the purpose of automatically removing highly
adhesive powder. When used in conjunction with an ultrasonic cleaner, it improves the cleaning effect of the screen.
