In view of the problem that the current screening device requires workers to manually pour the copper-clad iron powder into the device when in use, which increases the labor of the workers, and after screening, some of the copper-clad iron powder still adheres to the screen, causing waste of the copper-clad iron powder, the following scheme is proposed, which includes a screening box, a feeding assembly for automatically feeding the copper-clad iron powder is provided on one side of the screening box, a screening assembly for screening the copper-clad iron powder is provided inside the screening box, and a cleaning assembly is provided above the screening assembly. The device can not only vibrate and screen the copper-clad iron powder, but also automatically feed the copper-clad iron powder in the feeding box, reducing the labor of workers, improving the screening efficiency, and improving the screening effect. It is also convenient for cleaning and collecting the copper-clad iron powder attached to the screening trough, reducing the waste of copper-clad iron powder.

[0004] The existing technology has the following problems:

[0005] Although the above-mentioned utility model realizes the screening operation of iron powder, during the actual screening process, some iron powder will pass through the screen and fall into the receiving trough, while impurities will remain in the screening trough.
