Characteristic of the Automatic 3/5/7 ply corrugated cardboard production line：
1) The 3/5/7 layer corrugated cardboard production line is the key production equipment for corrugated carton box production enterprises, which includes several important components such as wet end equipment, dry end equipment, and production management system.
The corrugated board production line is composed of the following machines:
Electric /hydraulic shaftless mill roll stand, pre-heater, single facer, overhead conveyor bridge, double pre-heater, gluing machine, double facer, Thin blade slitter scorer, NC cutting machine, and stacker, heating system, air compression system and glue making system, etc.
2) Use corn starch glue to corrugate and glue craft paper rolls, continuously produce, cut, crease and cut into 3/5/7 layers of corrugated cardboard, and then convey, stack and output.
3) The production line has reasonable structure design, advanced production process, Higher productivity efficiency, better paperboard quality, strong batch adjustability. Using a central control system, simple and convenient operation, convenient repair and maintenance, reliable and safe, and greatly reduced the labor demand.
4) The effective width of corrugated cardboard is 1400mm-2500mm, and the production speed is 70m/min-300m/min, flute type: A,B,C,E,UV flute. It is an ideal equipment for corrugated paper box manufacturers.
5) High speed automatic corrugated cardboard production machine, Work continuously, is suitable for a large number of highly automated production, and can produce high-quality corrugated cardboard.
6）High-Quality Production Line: The 3-7 ply corrugated cardboard production line is designed to produce high-quality corrugated cardboard with a maximum speed of 300m/min and crosscutting accuracy of 1mm, ensuring uniform speed and precision.
7）Wide Range of Industries: This production line is applicable to various industries, including hotels, garment shops, manufacturing plants, and food & beverage factories, making it a versatile solution for businesses with diverse needs.
8）Long-Lasting Components: The core components, including the gearbox, pressure vessel, pump, gear, bearing, engine, motor, and PLC, come with a 1-year warranty, ensuring durability and reliability.
9）Comprehensive Support: A video outgoing-inspection and machinery test report are provided, giving customers confidence in the product's quality and performance.
