3/5/7 Ply Corrugated Cardboard Production Line
Used for making three/five/seven layer corrugated board
With the evolution of carton box packaging, the demand for advanced packaging technologies has significantly increased, particularly for export goods requiring stringent packaging standards. To meet the current demands, we have developed a high-speed, heavy-duty automatic corrugated cardboard production line, capable of producing a wide range of paperboard specifications within a certain range. This cardboard corrugation machinery features continuous operation, high automation, and exceptional production efficiency, making it an ideal solution for large and medium-sized carton box factories. Our corrugated board production line uses roll paper (both face and core paper) as raw materials. The whole process involves corrugating, gluing, and laminating to create 3/5/7-layer corrugated cardboard.
The corrugated cardboard production equipment offered by Huayu, was designed to cater to the growing demands for high quality packaging, to stand out for its versatility in manufacturing various specifications and for being able to sustain continuous, efficient production.
The complete corrugator is composed of several units that are connected by structural steel frame and conveying mechanism. Under the control of AC electromagnetic speed adjustment system (computer control), the corrugated cardboard production line can complete non-stop production from corrugated medium feeding to finished corrugated board discharging. It comes with high automation.

- Clamp the paper rolls on the mill stand that comes with shaft or not.
- Preheat the corrugated medium and linerboard on preheating cylinders and make them contain appropriate moisture.
- Feed the preheated medium and linerboard into the single facer and implement preheating once again.
- The top corrugated roll and bottom corrugated roll will press the corrugated medium to form flute. This is joined to a flat linerboard with adhesive to form single face board.
- Through lifting device, the single face corrugated board will be lifted to the overhead bridge conveyor and then be conveyed to the multiple pre-heater. During slow conveying, the single face board can be naturally dried.
- After being heated in the multiple pre-heater, the board will be conveyed into the gluing machine for another gluing.
- Then, via drying, bonding and cooling, we can get formed and flat corrugated boards.
- Further, in the slitter scorer, the corrugated board can be cut into required width. Via cross cutter, finally, the corrugated board with needed specifications can be produced.
- HUAYU provides all kinds of corrugation machines with breadth of 1.6-2.5m and machine speed of 60-180m/min. Our production line can produce 3-7 ply corrugated cardboards with various flute sizes. In addition, the corrugated boards come with uniform flute, high strength and precise size.
- The single facer of our corrugated cardboard production line employs vacuum suction type feeding. Corrugated rolls are processed by high precision CNC grinding machine. The largest diameter reaches Φ408mm.
- The double facer adopts fully modular design, realizing any combination of 10-21 heating boxes. Our double facer comes with the latest structure which can effectively avoid the disadvantages of traditional structures, thus improving production speed and reducing waste rate as well as lowering main motor power and decreasing driving belt wear.
- Rotary cross cutter of our corrugated cardboard production line is driven by servo motor which is controlled by computer, thus achieving high accuracy cutting.
- Thin blade slitter scorer is designed with 1.2m blades. During slitting, the paperboard edge is flat and has no burr and cracking. The blade boasts air cooling device and automatic re-sharpening device. Blade arrangement is controlled by computer. The time for changing specifications is 5-15 seconds.
- This corrugated cardboard production line is equipped with a lift type slitter which makes sure that the thin blade can cut the paperboard from its side, thus effectively avoiding printing side-lay edge and improving greatly printing quality.
- High speed feed double stacker is controlled by PLC with touch screen which is easy for man-machine interaction. The main motor features variable frequency control, thus saving energy. The stacker is available in automatic and manual options, reducing labor strength.
