Box opening machine

The utility model relates to the technical field of product packaging, in particular to a box opening machine which comprises a machine frame and a box opening mechanism. Box taking mechanism, whereinthe supporting plate is arranged on a guide rail in a sliding mode, the shaping assembly is arranged on the supporting plate, the adsorption assembly is arranged on the supporting plate in a liftingmode, and the driving piece drives the adsorption assembly to ascend and descend. The shaping assembly forms a shaping space for unfolding the paper box plate into a three-dimensional box, and the adsorption assembly is used for adsorbing the paper box plate and feeding the paper box plate into the shaping space; the box sealing mechanism is arranged at one end of the guide rail and used for folding and sealing the bottom of the three-dimensional box; the driving mechanism drives the supporting plate to slide along the guide rail, so that the adsorption assembly drives the three-dimensional box to get close to or away
