一种新型蜂窝纸板包边工艺及其制品缓冲性能研究

Analysis of a New Overlapping Technique for Honeycomb Paperboard and Its Energy Absorption Performance

提出了一种新型的蜂窝纸板包边工艺,以实现包边工序的机械化和自动化,并研究了该包边工艺下制品侧面的缓冲性能。对传统手工包边工艺生产的蜂窝纸板与所提出新型包边工艺生产的蜂窝纸板进行了对比实验,并采用多次曲线拟合的方法比较所得实验结果。研究结果表明,新型蜂窝纸板包边工艺是切实可行的,蜂窝纸板侧面在受集中载荷时,新型的包边工艺生产的蜂窝纸板的侧面缓冲吸能能力大于同种规格手工包边方式生产的蜂窝纸板;当蜂窝纸板的厚度小于40 mm时,传统手工包边工艺生产的蜂窝纸板的缓冲吸能能力随蜂窝纸板厚度的增加没有明显的变化趋势,而采用新型包边工艺生产的蜂窝纸板,其缓冲吸能能力随着蜂窝纸板厚度的增加而增强。

A new overlapping technique for honeycomb paperboard was presented, which could easily be mechanized and automated. The side energy absorption performance of the overlapped honeycomb paperboard was researched. Comparative experiments were carded out for the new technology processed honeycomb paperboard and traditional manual processed ones, with the experimental results analyzed by multiple curve fitting. The results showed that the new overlap- ping technique for honeycomb paperboard was feasible. Under concentrated load, the maximum capability of side energy absorption of the new honeycomb cardboard was greater than that of the traditional ones. With the existing traditional manual process, there was no obvious change in side energy absorption performance when the thickness of the honeycomb cardboard was less than 40 millimeter, while the side energy absorption performance of honeycomb cardboard made with the new overlapping technique was enhanced with the increase in thickness.
