The automatic hardboard production line is the core equipment in the packaging industry, and its technical level directly affects the quality, production efficiency, and cost of cardboard.

The main process flow of the industrial cardboard production line

A typical cardboard (taking corrugated cardboard as an example) production line includes the following key steps:
Raw paper preparation: Raw paper (face paper, core paper, inner paper) feeding, tension control.

Preheating treatment: By heating the base paper with steam, the plasticity is improved.

Adhesive drying: Starch adhesive bonding, drying and shaping.

Cooling and shaping: Reduce the temperature of the cardboard and stabilize its strength.

Vertical/horizontal cutting: Cut the cardboard size according to the requirements.

Stacking/Packaging: Automated stacking and packaging.

Development Trend of automatic grey board prodution line Industry

(1) Intelligence and digitalization

Industry 4.0 integration: Real time monitoring of device status and predictive maintenance through the Internet of Things (IoT). AI algorithms optimize production parameters such as temperature and speed.

Digital Twin: Virtual simulation debugging to reduce trial machine losses.

(2) Green manufacturing

Energy saving technology: heat pump drying, waste heat recovery to reduce energy consumption.

Environmentally friendly materials: biodegradable adhesives, recycled fiber base paper.

(3) Flexible production

Modular design: Quickly switch between producing different types of ribs (A/B/C/E ribs).

Small batch customization: adapting to the diverse needs of e-commerce packaging.

(4) High speed and high precision

Target speed: High end production lines can reach speeds of over 500 meters per minute (currently mainstream at 300-400 meters per minute).

Precision improvement: laser detection+closed-loop control, cutting error ≤ ± 0.2mm.

The technology of cardboard production lines is developing towards high-speed, intelligent, and green directions. Domestic enterprises need to break through key component technologies and improve automation levels to cope with high-end market competition. In the future, flexible production and digital management will become the core competitiveness of the industry.
