The invention relates to a finished anesthetic mask stacking and arranging device. The device comprises a base plate, a support, a workbench, stacking mechanisms and a discharging mechanism; the support is installed at the upper end of the base plate, the workbench is installed at the upper end of the support, a sliding groove is formed in the side wall of the base plate, and stacking mechanisms are installed in the sliding groove; the number of the stacking mechanisms is four, the four stacking mechanisms are uniformly arranged along the circumferential direction of the base plate, the discharging mechanism is arranged at the upper ends of the stacking mechanisms, and the discharging mechanism is installed on the base plate; each stacking mechanism comprises a mounting frame, a rotating frame, a stacking branched chain, an adjusting gear, an adjusting rack, a connecting plate, an adjusting air cylinder and a sliding plate; and the discharging mechanism comprises a placing frame, a discharging frame, a discharging motor, a lifting frame and a guide frame. According to the finished anesthetic mask stacking and arranging device, the problems of high manual dependence degree, low stacking efficiency, poor working continuity, easy falling of anesthetic masks, low stacking uniformity and the like in the existing anesthesia mask stacking process are solved.
