The invention discloses efficient full-automatic spraying equipment. The efficient full-automatic spraying equipment comprises a body and a first sliding cavity formed in the body. A sliding rack is slidably arranged front and back in the first sliding cavity through a sliding assembly, a first motor is fixedly arranged in the sliding rack, a driving shaft of the first motor stretches downward anda rotating rack is fixedly mounted at the tail end of the bottom of the driving shaft, a first cavity is formed in the rotating rack, a first rotating shaft stretching up and down is rotatably arranged in the first cavity, and the tail end of the bottom of the first rotating shaft is rotatably arranged in the bottom wall of the first cavity. The efficient full-automatic spraying equipment provided by the invention is simple in structure and convenient to operate, and is driven by a same power source to switch functions of polishing and derusting, dedusting and spraying. A moving mechanism controlled by an upper computer is also arranged in a processing course, so that a workpiece is sprayed uniformly. The steps are matched one another and do not affected one another, so that the sprayingefficiency and quality are improved, and the practical performance of the device is improved.
