When the cardboard original plate is transported between the adjacent limit plates and extends a certain length, the first reduction motor on the cutting mechanism is started, and the start of the first reduction motor will indirectly drive the cam to rotate. The rotation of the cam will cause reciprocating extrusion on the extrusion plate. The reciprocating extrusion of the extrusion plate will indirectly cause the cutting knife to reciprocate in the Y-axis direction. The cutting knife reciprocates in the Y-axis direction, thereby continuously cutting the cardboard original plate. Therefore, the utility model can continuously and quickly cut the cardboard in the conveying state, effectively improves the efficiency of cardboard cutting, and has strong practicality.
