一种新型蜂窝纸板包边工艺及其制品性能研究

A New Overlapping Technique for Honeycomb Paperboard and Product Properties

目的为实现蜂窝纸板包边工序的机械化和自动化,提出一种新型蜂窝纸板包边工艺,并对其制品的侧面载荷性能,即侧面戳穿的承载状况进行研究。方法提出了包含压溃、压痕、上胶、折边和侧面压紧等5个关键工序的新型包边工艺,并与现有手工包边工艺生产的蜂窝纸板进行对比实验,测试和分析了2种包边工艺生产的4种不同厚度蜂窝纸板,在侧边受集中载荷下戳穿所需的最大载荷。结果手工包边生产工艺的蜂窝纸板侧面受集中力时,最大戳穿力只与包边纸的性能有关系,蜂窝纸板厚度对其没有太大的影响;新型包边工艺生产的蜂窝纸板在侧面受集中力时,最大戳穿力与包边纸的性能有关,同时蜂窝纸板厚度对其也会产生较大影响;新型包边工艺生产的同种规格蜂窝纸板侧面戳穿所需的最大载荷大于手工包边方式生产。结论新型包边工艺大大提高了蜂窝纸板的侧面载荷能力,同时可实现机械化和自动化加工,极大地提高了蜂窝纸板后道工序的生产效率和产品质量。

A new overlapping technique was proposed in this study to mechanize and automate overlapping technique for honeycomb paperboard. The established new technology was then applied to study the properties of edge loading of overlapped honeycomb paperboard , i.e., the load bearing condition of edge-punctured. Five key processes of new overlapping technique for honeycomb paperboard were gained including crush, crease, sizing treatment, edgefold and side pressing. Comparative experiments were carried out for the new technology processed honeycomb paperboard and manual processed ones, then the maximum capability of edge loading were tested and analyzed for four different thicknesses of the two overlapping technique under concentrated load. Our results showed that under concentrated load, the maximum capability of edge loading of honeycomb cardboard made by existing manual process was only related to the material of overlapping paper, but with few impact from the thickness of honeycomb paperboard; however, that of honeycomb cardboard made by the presented new wrapping technology was not only related to the thickness of honeycomb paperboard but also correlated with the material of overlapping paper. Maximum capability of edge loading of honeycomb cardboard made by the presented new wrapping technology were greater than that of using the existing manual process. Maximum capability of edge loading of honeycomb cardboard was greatly improved by the presented new wrapping technology. In addition, the new technology is easy to mechanize and automate, which can greatly improve the productivity efficiency and quality through postprocess of honeycomb cardboard.
