Carton forming machine, including cardboard conveyor, unpacking device, carton back sealing device and carton conveyor. There are cardboard vertical conveying guide rods above both sides of the cardboard conveyor; the cardboard conveyor and the carton conveyor are vertically connected, and the unpacking device is located at the junction of the two, and is located above it, facing the carton conveying Machine's cardboard outlet. The unpacking device includes a movable suction cup mechanism that can approach or be away from the cardboard outlet, a swing lever mechanism that hangs above the cardboard outlet and has a rear upper edge that can hold up or release the cardboard, and a swing lever mechanism located under the cardboard outlet to allow The bulge of the lower folded edge after resisting the cardboard; an arc-shaped unpacking guide rod is also arranged on the outside of the suction cup mechanism. The carton forming machine of the invention has high production efficiency, the speed can reach 25-32 boxes/minute, the diagonal lines of the carton are neat, and the box body is well formed.
1. Prepare the carton that needs to be formed by the carton forming machine.
2. Turn the carton adjusting handwheel (clockwise forward, reverse backward) so that when the carton suction cup is at the limit position, the suction cup surface is parallel to the belt surface.
