The utility model discloses a multi-stage screening high reliability powder screening machine which comprises a machine frame and a vibration source arranged on the machine frame, a screen cloth inclining towards one side of the ground is arranged on the machine frame, the screen cloth is divided into a plurality of screening units in the inclining direction, and the diameters of screen meshes in the same screening unit are the same. The diameters of screen meshes of the different screening units are sequentially increased from the highest end to the lowest end, a material box is arranged below the rack and comprises a plurality of storage bins, and the storage bins are opposite to the screening units one to one. During use, powder needing to be screened is poured onto the screen from the top, and then the powder rolls down to one side of the ground under the action of a vibration source and gravity. In the process, multi-stage screening of the powder can be achieved under the action of the screening units wi
