    摘要:

    以回弹力作为蜂窝纸板易折叠性能的评价指标,设计了一种测试回弹力的方法。试验结果表明:随着压痕深度的增加,回弹力呈现先降后升的趋势;当压痕深度与纸芯厚度相等或比纸芯厚度稍大时,回弹力最小,此时蜂窝纸板保持压折状态的能力最好;对于孔径为6, 15, 20 mm的蜂窝纸板,钢刀刃口半径分别为1.0, 1.5, 2.0 mm时,其回弹力最小,故应随着蜂窝孔径的变化而调节压痕钢刀刃口半径,随着蜂窝孔径的增大,压痕钢刀刃口半径也应相应地增大。

    Abstract:

    A method is designed to test the resilience force by using it as the evaluation indicator of folding performance of honeycomb carton. The test results show with the increasing of the creasing depth, the resilience increases firstly and then decreases. When the creasing depth is equal to or thicker than core paper thickness, the resilience force is minimal; the ability of honeycomb paperboard is the best for staying in the state of creasing and folding position. For honeycomb paperboards with apertures of 6, 15, 20 mm, when the creasing rule radius are 1, 1.5, 2 mm respectively, the resilience is minimal. Therefore the creasing rule radius should be adjusted with the aperture sizes. The creasing rule radius should increase appropriately with the increasing of the honeycomb paperboard aperture size.
