The invention discloses a rotary wood door frame paint spraying apparatus. The rotary wood door frame paint spraying apparatus structurally comprises a worktable, supporting columns, an upper fixed seat, a rotating disc, a clamping device, a wood door, a limiting block, a groove, a transverse plate, a rotating device, a right paint spraying mechanism, a left paint spraying mechanism, a first semi-circular inner groove, a second semi-circular inner groove, a rolling wheel and a first rotating shaft. The supporting columns are arranged vertically in symmetry. According to the rotary wood door frame paint spraying apparatus disclosed by the invention, the wood door is fixed between the limiting block and a fixer, a gear ring drives the wood door to rotate, and the paint spraying mechanisms onthe supporting columns on two sides reciprocate up and down, and nozzles on the paint spraying mechanisms spray paint to the wood door all around. The paint spraying mode is simple. The rotary wood door frame paint spraying apparatus sprays paint to every position of the wood door uniformly, and is ideal in paint spraying effect.
