Cardboard Production Line, Corrugated Production Line, Paper Board
Production Line
Nowadays, the manufacture of corrugated cardboards is becoming
increasingly mature. All kinds of corrugated machines emerge as
times require. We devoted itself to development of the most
advanced and highest quality corrugated board making machine for
about 20 years. Today, our corrugated cardboard production
line is our great contribution to this packaging industry.
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.
Working Principle
- 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.
Main Features of Corrugated Cardboard Production Line
- We 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.
