Working principle of industrial Hardboard production line

The industrial cardboard (such as corrugated cardboard) production line processes the raw paper into a multi-layer composite structure through continuous processes, mainly divided into two main process stages: wet end equipment and dry end equipment.

1. Wet end equipment process

Raw paper processing: The raw paper is connected to the production line through an automatic paper feeder, and the temperature and humidity are adjusted by a preheating and pre adjustment device.

Corrugated forming: The single-sided corrugated machine presses the core paper into a corrugated shape and bonds it with the inner paper to form single-sided corrugated cardboard.

Composite bonding: Single sided corrugated paper enters the double-sided machine through the paper transfer bridge, and is bonded with the face paper/core paper by hot pressing after being coated, forming a 3-7 layer structure.

2. Cadre equipment process

Longitudinal cutting indentation: The rotary cutting machine cuts the edges of the cardboard according to the order requirements, and the computerized paper separation and pressing machine synchronously completes the indentation.

Cross cutting stacking: The cross cutting machine cuts according to the set length, and the stacking machine automatically stacks the finished products.

Intelligent control: The production management system monitors parameters in real-time, such as vehicle speed and glue volume, to optimize efficiency and quality.

Technical Features of the industrial cardboard production line

Automation: shaftless paper racks and automatic paper feeders reduce manual intervention.

Energy saving design: Preheaters utilize waste heat to reduce energy consumption.

High precision: The longitudinal cutting error can be controlled within ± 0.5mm.
