Corrugated Cardboard Production Line is the professional equipment for producing corrugated cardboard.The 3ply,5ply,7ply,and multi-function corrugated cardboard production line mainly consist of the following equipment :Mill Roll Stand, surface paper(core-paper) pre-heater.Single facer, Conveying Span Bridge.Glue Application Machine, Double Facer.Slitter Scorer,Cut-off,Conveyer and Stacker.Heating System.Air compression system and Glue Making System,etc.The 3ply,5ply,7ply,and multi-function corrugated cardboard productiong line has high middle and low grade with different-specification and different-quality equipment. On the base of understanding the requirements of the customers and the advanced skills at home and abroad, our company has developed and designed these production lines with the speed 100-220m/in;the paper width 1600-2200mm and four fluting UV type A,B,C,E for all the customers to choose from. SF380T Single Facer Design Speed: 200m/min Effective width: 1400mm-2500mm Corrugated roller:φ380mm Fingerless vacuum suction type single facer, the upper and lower corrugated roller made of 48 CrMo alloy steel,with harted treatment,the hardness is above HRC58o-60°The surface is well treated by grind and plated chrome. Upper and lower corrugated roller are unit assemblage, the whole corrugated rollers group can be move and quick replacement, to change flute type quickly. Glue section are unit assemblage, whole section can be moved by track,save maintenance time. Frequency conversion motor as main drive , independent gear box connect with three gimbal axis, Inverter to make stepless speed regulation for save power, and to keep one communication connector for production management. Oil immersed type lubricating to reduce noise keep running stable, prolong the use life of gear. Adopt Glue width motorized dividing to match the paper width. Idle running motor for glue applicator roll to avoid glue dry.Adjustment for gap between glue roller and doctor roller by electric or manual are optional, Digital read out for the gap between glue roll and doctor roll is optional. Adjustment for corrugated roller,pressure roller,and glue roller by pneumatic system. With preheater for liner paper and steam spray device for medium paper. Bearing for corrugated rollers,and pressure roler adopt high-temperature lubricate grease to keep running smoothly and durably.
