2.95M Single Facer Line: A Benchmark for Wide-Width Paperboard Production with Smart Manufacturing
In the production workshop of Zaozhuang Hanteland Banner, the 2.95M wide Single Facer line, jointly built by Qingdao JUSTU and Shandong Zaozhuang Packaging, operates at an efficient and steady pace, standing as a vivid example of intelligent manufacturing in the packaging industry.
The core advantage of this production line first lies in its speed: the current running speed stabilizes at 190m/min, with an average speed maintained at a high level of 108.9m/min, far exceeding the industry's conventional standards. This efficiency is supported by its three core configurations: the dual-blade 7-7 high-precision cutting system controls cutting errors to within 0.1mm, ensuring smooth cuts on wide-width paperboards; the fully servo dual-station paper feeder reduces roll-changing gaps to less than 3 seconds, minimizing production downtime; and the 2950mm intelligent tension matrix keeps the flatness of wide-width paperboards at ≤0.3mm/m during high-speed operation, fundamentally guaranteeing product quality.
The operation electronic cabinet serves as the "nerve center" of the entire line. The Single Facer Management System V3.0.5 displays key data in real time, including running speed, remaining length, and production area. On the screen, details such as the current cut length of 685mm and remaining length of 2544.8m are clearly visible. Production time has accumulated to 1 hour 07 minutes 42 seconds, with zero downtime, directly confirming the equipment's stability.
In the mechanical operation phase, the corrugating rolls rotate at high speed under precise transmission, pressing raw paper into regular corrugated waves and bonding it accurately with liner paper. The synchronized cutting system automatically trims according to the set dimensions, with each cut executed with pinpoint accuracy. The formed paperboards then enter the logistics modular belt conveyor platform, where the green conveyor belt transports them smoothly at a speed matching the production line, seamlessly connecting to subsequent processes. Workers on both sides of the platform only need to perform simple inspections and sorting, without frequent intervention, achieving efficient collaboration between automation and manual labor.
From the precise control of the electronic cabinet to the high-speed operation of machinery and the stable transportation of the logistics platform, this 2.95M Single Facer line demonstrates the efficiency and precision of wide-width paperboard production through a fully intelligent workflow, providing a replicable model for the large-scale and intelligent upgrading of the packaging industry.
