The invention relates to the technical field of advanced manufacturing, in particular to a quick product spraying device based on an advanced manufacturing production line. The quick product sprayingdevice comprises a base, a feeding mechanism, a spraying mechanism, a spraying chamber, a drying chamber and an air drying chamber, wherein the feeding mechanism comprises a feeding plate, the two sides of the upper end of the feeding plate are correspondingly provided with side plates, and the portions, located at the inner sides of the side plates, of the upper end of the feeding plate are provided with clamping plates. According to the quick product spraying device, upper-and-down opposite spraying design is adopted, materials in an upper spraying plate and a lower spraying plate are uniformly conveyed, and the balance in spraying is improved. Moreover, through the cooperation of an infrared emitter and an infrared receiver, the upper spraying plate and the lower spraying plate can be automatically controlled to conduct spraying, an upper drying plate and a lower drying plate in the drying chamber simultaneously conduct targeted drying on the upper and lower faces of panels, and besides, opposite-jetting air outlets are designed in the air drying chamber and can comprehensively blow air to the panels to air-dry the panels. Moreover, the quick product spraying device integrates functions of spraying, drying and air drying, and the processing efficiency of spraying the panels is improved.
