The grey hardboard production line usually includes the following main components:

Paper rack: used for placing and supplying paper.

Bridge conveyor: Transport paper from one process to another.

Glue coating machine: used to apply glue on paper.

Compactor: Compact the paper coated with glue to bond it together.

Drying board dryer: By heating, the glue is dried to enhance the hardness and stability of the cardboard.

Cooling section: Cool the dried cardboard to the appropriate temperature and humidity.

Vertical and horizontal cutting machine: Cut cardboard into different sizes as needed.

These automatic hardboard production lines usually have the characteristics of advanced production technology, reasonable design, convenient operation and maintenance, safety and reliability, energy conservation, and no environmental pollution. They can be laminated with three-layer, four layer, five layer, and six layer cardboard, with a maximum thickness of 3.5mm, suitable for producing new packaging materials such as cardboard boxes, paper boxes, high-end gift boxes, stationery supplies, etc.

In addition, there are some special equipment for producing grey cardboard, such as a double grey cardboard production device, which includes a glue storage section, a glue cleaning section, and a glue coating section. This can avoid the solidification of the glue when the glue coating roller and the glue cotton roller are idle, and solve the problem of uneven coating caused by the glue still attached to the outer wall after processing due to the glue being applied through the rotating roller.

When choosing industrial cardboard production line , factors such as production scale, production speed, thickness and number of layers of cardboard, and the degree of automation of the equipment need to be considered. Meanwhile, it is also necessary to consider the maintenance and upkeep of the equipment to ensure its long-term stable operation.
