Composition of Corrugated Paperboard Production Line

The corrugated paperboard production line is composed of two relatively independent process sections: the wet end equipment and the dry end equipment.

The wet end equipment mainly includes the mill roll stand, automatic splicer machine, single-face and double-face corrugated machine , preheater, overbridge, glue machine, and other equipment. The wet end equipment processes the corrugated raw paper into three, five, or seven layers of corrugated paperboard with different flute combinations.

The dry end equipment mainly consists of slitter scorer, cross cutter, and stacker and so on. The dry end equipment performs longitudinal slitting, scoring, cross-cutting, and stacking of corrugated cardboard according to the requirements of the orders.

Production Process of Corrugated Paperboard Production Line

Firstly, the paper rolls are placed on the mill roller stand in a specific direction. Each web of paper is preheated using a preheater to heat its surface and facilitate adhesion. The corrugated raw paper undergoes preheating and moisture adjustment through a pre-conditioner before being fed into the single facer to ensure the paper’s smoothness.

Subsequently, the corrugated raw paper enters the single facer for corrugation, adhesive application, and bonding with the liner paper, forming single-faced corrugated board. After the production of single-faced corrugated board, it is lifted by a conveyor and conveyed to the overbridge conveyor frame, passing through a brake to enter the preheater.

Next, the two types of single-faced corrugated boards are separately fed into the gluer for adhesive application. The liner paper undergoes another round of preheating. The three components are then fed into the double facer’s drying equipment for bonding and drying.

After the corrugated board is heat-bonded, it goes through a cooling process to allow the evaporated moisture to escape. Once the board cools down on the conveyor belt of the drying equipment, it is cut horizontally to specific dimensions using a computerized cross-cutting knife. Finally, the boards are conveyed to the stacker and neatly piled up.
