The invention discloses a full-automatic boxing system and method. The system comprises a cargo loading mechanism used for loading cargoes, the cargo loading mechanism is connected with a first conveying mechanism, and the to-be-boxed cargoes are conveyed to a boxing mechanism through the first conveying mechanism; a second conveying mechanism is arranged at the other end of the boxing mechanism, and the tail end of the second conveying mechanism is connected with a corrugated paper box making mechanism; a corrugated paper conveying mechanism is connected to the tail end of the corrugated paper box making mechanism, corrugated paper is conveyed to the corrugated paper box making mechanism through the corrugated paper conveying mechanism, the corrugated paper is cut, the cut corrugated paper is conveyed to a box body forming mechanism through the second conveying mechanism, the corrugated paper is folded through the box body forming mechanism to form a box body, and the formed box body is conveyed to the boxing mechanism to box the cargos. By means of the full-automatic boxing system, full-automatic boxing of the cargos is achieved, manpower is liberated, and the boxing efficiency is improved.
