The application relates to a feeding device for
tungsten powder preparation, in particular to a full-automatic auxiliary feeding device for
tungsten powder preparation, which solves the problems of low
automation degree, inconvenience in uniform paving and low feeding efficiency of the auxiliary feeding equipment for
tungsten trioxide, a
raw material, in tungsten
powder preparation, and provides the following scheme, which comprises a base, a tray, a spring one, an extension piece, a feeding cylinder, a pin shaft seat one, a pin shaft, a sleeve seat, a rotating shaft, a material paving hopper, a resisting frame, an opening and closing
assembly, a sliding seat, a plug-in cylinder, a swing
assembly, a driving
assembly and a rotating ring, a vibrating assembly is arranged on the rotating ring, the vibrating assembly is used for driving the tray, the feeding cylinder and the material paving hopper on the tray to vibrate relative to the base when the sliding seat is driven to reciprocatingly slide, so that the
tungsten trioxide powder in the feeding cylinder and the material paving hopper is vibrated to completely
discharge the material when the material is discharged. The device can rapidly convey the tungsten powder preparation
raw material, and facilitates automatic paving, and improves the efficiency and stability of the
raw material conveying for tungsten powder preparation.
