The basic working principle of a folding box machine is to automatically fold pre cut flat cardboard into the desired box shape through a series of precise mechanical actions. The device first sends the flat cardboard into the work area through suction cups or conveyor belts, and then completes the precise folding of each fold through pre-set programs such as folding wheels and folding arms. Finally, the box shape is fixed by gluing or tongue insertion. The entire process is fast and coherent, and dozens or even hundreds of boxes can be folded every minute.
