2. Key Components and Their Functions
Hydraulic Mill Roll Stand
The Hydraulic Mill Roll Stand (Model YZJ6-2200) is the foundation of this line, designed for heavy-duty paper roll handling. With hydraulic lifting, lateral movement, and multi-point pneumatic tension control, it ensures continuous feeding with zero downtime. Each unit includes 8-meter rails for smooth loading, reducing manual intervention and improving productivity.
Cassette Single Facer Double Roller
The Cassette Single Facer Double Roller (Model KFW4-2200) features vacuum inside type, universal coupling drive, and 420 mm flute roll diameter. The rolls are made of Ni-Cr-Mo alloy steel with tungsten carbide coating, guaranteeing 26–30 million meters of service life. The quick-change cassette design allows flute roll replacement within 20 minutes — optimizing flexibility for different corrugated carton production line demands.
Preheater and Gluing Machine
The Preheater Series (MY4-2200, XY4-2200, DY4-2200) uses electric adjustable heating zones (60–350°C), ensuring stable moisture control and bonding strength. The Duplex and Three-Layer Gluing Machines adopt pressing-type gluing methods, stainless steel glue tanks, and servo synchronization to guarantee precise glue application across all paper layers.
Overbridge Conveyor
The Overbridge Conveyor (GQ4-2200) connects single facers to the double facer, equipped with infrared alignment, automatic edge control, and independent motor drive. Its German-engineered system ensures perfect alignment of top, middle, and bottom sheets—crucial for multi-ply corrugated board accuracy.
Double Facer
The Double Facer HE420 combines 12–14 heating plates, airbag pressure control, and cooling zones with heavy press rolls. Its hydraulic lifting and pneumatic correction system stabilize board bonding while preventing warping. This ensures uniform heating and pressure for flawless bonding at high speed.
Computer Thin Blade Machine
The Computer Thin Blade Machine offers 5 knives and 8 scoring lines with ±0.5 mm accuracy. It utilizes servo-driven slitting and scoring, auto grinding, and real-time synchronization with the line’s speed. The intelligent control via PLC and touch screen ensures seamless integration with production orders.
Helical Knives NC Cutting Machine
The Helical Knives NC Cutting Machine (HQ2-2200) features AC servo control, low inertia spiral cutting, and ±1 mm precision. It enables smooth, efficient, and burr-free cutting for all sizes of corrugated sheets, improving quality and reducing material waste.
Automatic Stacking System
The DM4-2200 Automatic Stacker uses servo-controlled offset stacking, 5-section conveyor belts, and synchronized order changing. It ensures clean, uniform stacking, saving labor while maintaining continuous production flow.
Automatic Glue Making Machine
The QZJ-1500 Glue Making Machine automates glue preparation with PLC control, temperature monitoring, and real-time alarms for ingredient shortages or overheating. It ensures consistent viscosity and saves up to 30% of glue consumption.
Auxiliary Systems
Complementary systems like Steam Heating, Compressed Air, and Electrical Control (inverter + PLC integration) ensure overall process stability. The Production Management System tracks each unit’s performance, synchronizes order changes, and provides real-time data display.
