The invention relates to a folding machine for a paper box, which is used for automatically producing a packaging paper box. The folding machine overcomes the defect that an adhesive is required by the process of mechanically folding the paper box (case). The folding machine for the paper box can automatically finish a complex folding operation and the paper box is manufactured without using any adhesive or other fixing connector. According to the specific scheme, the folding machine for the paper box comprises a frame, wherein a loading device, a conveying device, a folding device, an outputting device and an intelligent control component for allocating individual operation of each device are arranged on the frame; the loading device comprises a lifting component which can be lifted along a vertical direction; the conveying device comprises a linear moving component which can move along a horizontal direction; the folding machine is characterized by comprising a supporting plate for supporting a paper box blank plate; a downward pressing component for pressing the paper box blank plate from top to bottom is arranged above the supporting plate; and a lateral pressing component and a turning component for folding a lateral surface and an end surface are arranged on the periphery of the supporting plate.
