Main links on the corrugated cardboard production line

Corrugated cardboard production line on the biggest loss mainly comes from the strength of paperboard is greatly reduced. Once the board strength greatly reduced, it is necessary to increase the weight of paper to ensure its strength, weight and costs directly with the base paper. Therefore, to ensure the strength of cardboard is to ensure the cost. The strength of the board is mainly determined by the width of the wire. In Europe and the United States, the quality inspection of corrugated boxes, one of the most important is the corrugated cardboard line width check. Some domestic corrugated cardboard glue line width reaches 2.5 ~ 3.0mm, the board strength is very weak, it is necessary to improve the paper weight lifting strength of paperboard.

There are two aspects to control the width of viscose wire.

On the one hand is the equipment control. If the manufacturing of high precision equipment, small beating uniform roller, the accuracy rate of viscose is big. Therefore, single side machine, gluing machine is accurate, precise, uniform glue is the main factor to control the width of viscose wire. In particular, the two gluing machine, can be called the soul of the cardboard production line. Foreign BHS and Mitsubishi Co and other cardboard production lines are accurate, precise, even on behalf of the domestic line in the glue on the relative accuracy is much smaller. www.chinacartonmachine.com

Secondly, the intrinsic quality of the glue is high. The glue is not uniform, not only can increase the width of the bonding line to improve the bonding effect. However, in recent years, paperboard weight greatly reduced, weight from the original 250g down to the present 150g, the bond line is too wide will cause the glue penetration through the corrugated cardboard cardboard, cause. Therefore, to ensure the quality of cardboard must strictly control the width of the viscose wire.
