Advanced Modules of Standard 3 5 7 Ply Corrugated Cardboard Production Line
Hydraulic Mill Roll Stand and Electric Mill Roll Stand
These modules handle heavy rolls with hydraulic lifting and clamping mechanisms, ensuring efficient feeding and paper tension control. Their shaftless chuck design and centralized pneumatic braking minimize downtime and guarantee steady material delivery, forming the foundation of the corrugated cardboard production line.
Cassette Single Facer and Cassette Single Facer Double Roller
Equipped with a fingerless vacuum system, flute roll quick-change cassette, and gear-drive transmission, the cassette single facer ensures quick flute conversion between A/B/C/E types. The double roller configuration enhances speed stability while preserving precise flute geometry for better carton compression strength.
Preheater and Gluing Machine
The preheater regulates paper temperature between 60°C and 350°C, maintaining ideal moisture for adhesive bonding. The gluing machine—available in single, duplex, or triple type—adopts precision roller application, servo control, and stainless-steel glue tanks for uniform coating. Together, they ensure optimal adhesion and prevent delamination during stacking or folding.
Overbridge Conveyor
This key link in the Standard 3 5 7 Ply Corrugated Cardboard Production Line transfers single-faced paper to the double facer through an intelligent conveyor network. Equipped with photoelectric sensors, air-guided alignment, and motorized synchronization, it guarantees exact paper overlap, reducing waste and maintaining board uniformity.
Double Facer
The Double Facer combines airbag pressure system, 14-section heating plates, and cooling rollers to stabilize board bonding at high speed. Its precision temperature zones prevent edge curling and ensure consistent flatness, a hallmark of BMC Pack’s production technology.
Computer Thin Blade Machine
Integrated with five cutting blades and eight scoring wheels, the computer thin blade machine offers ±0.5 mm accuracy through servo synchronization. The automatic blade grinding and computerized order management system reduce downtime, improving both efficiency and safety.
Helical Knives NC Cutting Machine
Driven by a servo motor system, this NC cutter performs fast, smooth, burr-free trimming of corrugated boards. Precision helical blades ensure clean edges and minimal dust generation, vital for maintaining downstream creasing and die cutting accuracy.
Computer 2 Ply Corrugated Cutter and Stacker
For multi-layer setups, this unit automates the cutting, sorting, and stacking of 2-ply sheets with servo control. It ensures continuous feeding and reduces manual handling, making the production process safer and more efficient.
System Integration and Control
The entire Standard 3 5 7 Ply Corrugated Cardboard Production Line is governed by an intelligent PLC system with touch-screen interface, enabling real-time monitoring, auto fault detection, and digital synchronization of all modules. Operators can easily adjust parameters to match order specifications, while BMC Pack’s modular architecture allows upgrades with Flexo Printing Machines, Rotary Die Cutters, or Folder Gluer Machines for a complete packaging solution.
Energy Efficiency and Maintenance Advantages
Energy-saving is a core philosophy of BMCPack’s engineering. Components like preheater, double facer, and Hydraulic Mill Roll Stand are optimized for low energy loss and long service life.
