A 3D printing equipment anti-clogging metal powder precision powder supply device

Abstract

This utility model discloses a precise powder supply device for anti-clogging metal powder in 3D printing equipment, relating to the field of powder supply technology for 3D printing equipment. The device includes a powder supply tank, metal powder inside the tank, a fluidizing tank, and a platform. It also includes a fluidization assembly disposed inside the fluidizing tank, comprising a limiting ring, a rotating ring, and a pressure ball. In this utility model, after the metal powder flows from the fluidizing tank into the fluidization assembly, a first servo motor is activated. The first servo motor drives the drive gear, auxiliary gear, and rotating ring to rotate synchronously, causing the pressure ball inside the rotating ring to continuously press against the metal powder. This causes the metal powder to move between particles, eliminating static friction and breaking down the stress of metal accumulation, resulting in higher fluidity and improved anti-clogging capability of the powder supply device.
