The invention provides a classified recovery device for empty packaging boxes. The classified recovery device comprises a storage bin, a support I, a packaging box transferring device, a box throwing device and a layer staggering device; a bar code recognizer reads printing bar codes of the empty packaging boxes at the uppermost end in the storage bin, a stacking machine or a shuttling trolley drives a cargo-loading table to move to a corresponding cargo box storing the empty packaging boxes of the specification after the bar codes are recognized, then the packaging box transferring device conveys the empty packaging boxes at the bottommost end forwards, and finally the empty packaging boxes at the bottommost end are thrown into cargo boxes for storage after being accelerated by the box throwing device; the layer staggering device is used for staggering layers of the packaging boxes and blocking the packaging boxes at the upper end, the packaging boxes at the upper layer can be prevented from moving forwards along with the packaging boxes at the lower layer through the layer staggering treatment, and meanwhile, mutual meshing of edge hinges of two packaging boxes can be effectively prevented. A retractable fork can take out the empty packaging boxes of the same specification stored in the cargo boxes, and therefore storage and delivery can share one port, the efficiency is improved, and consumption of manpower and material resources is reduced.
