Pre-store die-cut box blanks, up to 400 pieces.


  • Pneumatic System

Adsorb the die-cut box blank and then transport the blank to the box-forming station.


  • Carton Forming Unit

Fold the snap lock bottom box’s female bottom closure panel and two closure flaps.

Two vacuum suction cups suck a box blank from the blank magazine, and then move the box blank to the box forming station.


The lead screw that holds the blank magazine is adjustable, and adjusting the lead screw can make the magazine fit your carton size.

  • Box Forming

After the box blank arrives at the carton forming station, it is detected by the photoelectric eye first, and the photoelectric eye feeds back a signal to the PLC.


Then, the PLC sends a command, the other two vacuum suction cups absorb the box blank and generate a reverse pulling force on the box blank, and the two reverse pulling forces erect the box blank into a square shape.

  • Output Erected Box

After completing the bottom interlocking, the tucker will push the erected box out of the bottom locking station, and the erected boxes with open tops drop into the pre-placed collection cardboard box.
