Hub spraying equipment and method thereof

The invention relates to the technical field of automobile hub spraying, in particular to hub spraying equipment and a method thereof. The hub spraying equipment comprises a workbench, a sliding rail, a sliding block, a driving assembly, a connecting piece, a connecting rod, a square block, a connecting cylinder, a tray, a transmission gear, a transmission rack, a guiding piece, a rotating assembly and the like, the top of the workbench is connected with the sliding rail, and the driving assembly is installed in the middle of the top of the workbench. A chain in the driving assembly is matched with a chain wheel, annular continuous conveying of hubs is achieved, spraying is carried out when the hubs reach the designated position, the hubs are continuously conveyed to the discharging area after spraying, then discharging is carried out, workers only need to intermittently add the hubs and intermittently unload the sprayed hubs, the non-productive time is shortened, and the production efficiency is improved.
