5 Layer Corrugated Cardboard Production Line , Electrical Cardboard Packaging Machine

  It is mainly composed of mill roll stand,single-roller pre-heater,single facer,overbridge,multi-roller pre-heater,pasting machine,double facer,cutting machine,slitting machine ,sheet stand,NC cut off and stacking machine as well as glue making system,electric control system and so on.

  Workflow:The paper shall be transmitted from mill roll stand to single-roller pre-heater for pre-heating and humidity adjusting,to single facer for further heating,fluting and gluing to be single corrugated sheet,then to overbridge through pulling for orderly transmitting,to multi-roller pre-heater for again heating,to pasting machine for gluing ,to double facer for bottom paper combination to be corrugated sheet,slitting machine and NC cut off for required sheet and lastly to stacking machine for stacking and outputting.
