Adjusting the equipment of the automatic hardboard production line requires systematic operation to ensure production efficiency and product quality.

1、 Preparation work before adjustment

Check the equipment status: Confirm that all components (such as the raw paper holder, preheater, glue coating machine, forming wheel, hot plate, cooling section, cutting machine, etc.) have no mechanical faults. Check if the electrical, pneumatic, and hydraulic systems are functioning properly.

Clear production parameters: Determine the number of cardboard layers (single corrugated, double corrugated), weight, width, speed, etc. according to the order requirements. Prepare corresponding molds (such as slotting molds, wire pressing wheels) and adhesive formulas.

2、 Step by step adjustment of grey board production line

1. Raw paper holder and tension control

Adjust the position of the base paper: Ensure that the base paper roll is centered to avoid deviation.

Tension control: Adjust the tension through magnetic powder brake or pneumatic brake. If it is too tight, the paper may break, and if it is too loose, it may cause wrinkles.

2. Preheater

Temperature setting: usually 120-180 ℃ (adjusted according to paper weight and humidity).
Adjustment angle: Control the angle of the paper wrapping preheating roller to ensure sufficient preheating but not excessive drying.

3. Single sided machine (corrugated forming)

Glue quantity control: Adjust the thickness of the glue by adjusting the gap and speed of the glue roller to avoid insufficient or overflowing glue.

4. Double sided machine (bonding section)

Hot plate temperature: generally 160-200 ℃, which needs to be matched with the production line speed (the faster the speed, the higher the temperature).

Pressure band tension: Ensure a tight fit and avoid foaming or delamination.

5. Drying and cooling

Drying section: Maintain good ventilation to avoid warping of the cardboard.

Cooling section: Adjust the fan speed and conveyor belt speed to shape the cardboard.

6. Cutting and Stacking

Cutting accuracy: Calibrate the positioning system of longitudinal and transverse cutting tools (such as photoelectric sensors or encoders).

Stacking neatness: Adjust the height of the baffle and the pushing force of the stacker.
Through the above steps, the equipment adjustment of the Composite cardboard production line can be systematically completed. If the problem is complex, it is recommended to contact the equipment manufacturer or professional engineer for assistance.
