Abstract

The utility model relates to the technical field of spraying processing equipment, in particular to an airborne spiral powder feeding mechanism which comprises a mounting assembly, a horizontal powder feeding assembly and a vertical powder feeding assembly. The vertical powder feeding assembly is provided with a powder inlet communicating with an inner cavity of the vertical powder feeding assembly, an inner cavity of the vertical powder feeding assembly communicates with an inner cavity of the horizontal powder feeding assembly, and the vertical powder feeding assembly can convey powder entering from the powder inlet into the horizontal powder feeding assembly. The horizontal powder feeding assembly is used for receiving powder and feeding the powder into the vacuum coating furnace through the horizontal screwing assembly. According to the powder feeding device, firstly, powder enters the vertical powder feeding assembly through the powder inlet in the vertical powder feeding assembly, the vertical powder feeding assembly can convey the powder to the horizontal powder feeding assembly, the horizontal powder feeding assembly is arranged below the vertical powder feeding assembly, in other words, powder feeding directions in different directions are adopted, and therefore the powder can be evenly conveyed; and the phenomena of transmission retardation and unstable powder feeding rate are avoided.
