The operation of the automatic hardboard production line involves multiple key links, including raw material preparation, production process control, equipment maintenance, etc. Here are some basic operating principles:

Raw material preparation: Ensure that the moisture content of the raw paper used is appropriate, generally between 6% and 8%, to facilitate the molding and bonding of the cardboard. The production date of the base paper should be similar to maintain consistent quality.

Adhesive indicators: Adjust the viscosity and solid content of the adhesive according to the season to adapt to different production conditions.

Preheating and compaction: The temperature of the preheating drum and hot press plate must meet the specified standards to ensure the drying of the cardboard and the formation of hard cardboard. The size of the preheating corner should be adjusted according to the moisture content of the base paper and the degree of bending of the cardboard.

Tension adjustment: The tension of the base paper should be adjusted appropriately according to the longitudinal bending degree of the cardboard to prevent paper breakage or cardboard bubbling and warping. grey board paper making machine

Humidity control: Moderate stacking of paper at the bridge can help evaporate moisture, but excessive stacking may cause cardboard deformation. Therefore, the stacking amount of paper should be reasonably controlled according to the board output effect.

Dust removal system: Use a dust removal system to remove paper wool and dust from cardboard, in order to improve the quality of the subsequent printing process.

Steam and hot press plate control: Ensure sufficient steam pressure and hot press plate temperature to achieve good paperboard production results. Adjust the hot press plate according to the size and bending degree of the cardboard.

Size scheduling: Avoid immediately replacing larger cardboard with smaller cardboard after production to avoid affecting the quality of the cardboard.

Pressure regulation: The pressure regulation between the upper and lower rollers and the pressure roller is crucial for paperboard forming. The adjustment of adhesive gap can also affect the stiffness and bonding effect of the cardboard.

Vehicle speed control: The vehicle speed should be adjusted according to the size and production conditions of the cardboard to ensure its flatness.

Equipment maintenance: Regularly inspect and clean the impurities on the surface of the hot press plate to ensure clean and smooth operation during the production process.

Delivery: Ensure that the delivery is neat and orderly for subsequent storage and transportation.

Please note that the above operation guidelines are based on the general operating principles of the cardboard production line, and the specific operation details may vary depending on different models and configurations of the production line. Before operation, carefully read the equipment manual and operation guide, and receive professional training. At the same time, continuously monitor various parameters in the production process and adjust them in a timely manner to ensure product quality.
