The invention provides a quick stereoscopic packaging machine which is used for packaging box face plates. Each box face plate to be packaged comprises a plurality of side face plates which are integrally connected with one another in a folded manner. The packaging machine which is a forming machine comprises a framework and a connecting bar mechanism. A box inner mold, a lower support part, a side face plate overturning assembly and a pressure mechanism are arranged on the framework, the side face plate overturning assembly is positioned on two sides of the lower support part, the pressure mechanism is positioned above the box inner mold, and a gap is formed between the lower support part and the box inner mold, so that the certain box face plate to be packaged can be supported by the gap and clings to the lower side surface of the box inner mold; the side face plate overturning assembly is arranged on the framework in an overturning manner, and the connecting bar mechanism and the side face plate overturning assembly are connected with each other to push the side face plates of the certain box face plate to be packaged to be overturned, so that the side face plates can cling to the box inner mold; the pressure mechanism is used for pressing the certain box face plate which clings to the box inner mold to form a box. The quick stereoscopic packaging machine which is the forming machine has the advantages that the connecting bar mechanism pushes the side plate overturning assembly to overturn, so that encircling operation can be automatically performed on the box, actions are coherent and quick in an integral forming procedure, and the box can be quickly and automatically formed.
