The invention discloses a printing notching machine which comprises a notching treatment device, an output end opening, a treatment box to be output, a protection separation layer, an observation side, a printing treatment joining box and a control button. The observation side is embedded into the protection separation layer and is located in the middle, and the bottom end of the observation button is embedded into the top end of the printing treatment joining box. The notching treatment device comprises a printing coloring set, a master control electricity box, a push starting magnetic fieldset, a heating pushing device, a sliding cutting set, a movable treatment device, friction power generating equipment and a protection shell. The printing coloring set is located below the master control electricity box, and the movable treatment device is mounted at the bottom end in the protection shell. Based on the prior art, when an object is still in a plane and a notching cutter falls down,an operation table below the object is moved towards one side, the lower portion of the object is vacated, the notching cutter carries out cutting along a clearance, and the object can be cut open more easily.
