【摘要】：自从加入世贸组织以来，我国的进出口贸易变得越来越活跃，国外市场给我国包装市场带来机遇的同时，也对我国的包装工业提出了新的挑战。发达国家利用绿色环保材料已经越来越普遍，而我国的包装行业木材和塑料还占据着较大市场。在此现状下“以纸带木，以纸带塑”显得尤为重要，蜂窝纸板作为一种绿色包装材料，如果大量应用在包装行业不仅节省木材资源，，而且可以减少塑料包装带来的环境污染。我国的蜂窝纸板行业发展至今约二十年，蜂窝纸板的制造工艺和制造设备还比较落后，国内的学者和企业技术专家也进行了大量的研究，但大多是针对蜂窝纸板的力学性能，对蜂窝纸板的工艺和设备的研究很少，而成型工艺与设备直接影响着蜂窝纸板的力学性能。因此将蜂窝纸板的工艺、性能与设备三者紧密联系在一起的研究具有重要的现实意义。本课题基于工艺设备对纸板力学性能的影响，分析了现有工艺设备存在的问题：为生产不同孔径的蜂窝纸板，需要设计一系列备用涂胶辊；蜂窝纸板干燥不均，干燥时间长；蜂窝纸堆切条速度慢。利用有限元分析软件ANSYS研究了纵横向涂胶和开孔对蜂窝纸板力学性能的影响，设计了一种多功能涂胶机构和开孔切条设备。利用三维软件Pro/E建立了蜂窝纸板主要受力部分纸芯的模型，并将模型导入有限元分析软件ANSYS中，分析纵横涂胶，不同开孔位置，开孔形状和开孔大小对蜂窝纸板力学性能的影响，研究了开孔后的干燥效果，为涂胶设备和开孔切条设备设计提供依据；设计了基于纵向涂胶的多功能涂胶设备，绘制了该设备三维模型，分析了胶条间距调节的原理和可行性，并通过涂胶试验验证了该设备的行性，解决了需要生产一系列备用涂胶辊的问题，减低了设备成本；设计了开孔切条设备，绘制了三维模型，该设备通过多个孔刀和旋转刀片实现开孔和切条，并对开孔部分的受力机架进行了结构优化，减小机架的应力集中，试制了经过开孔切条处理的带圆孔蜂窝纸芯条和纸板，验证了干燥效果，此开孔切条机能有效解决蜂窝纸板干燥困难和切条效率低等问题。这些机构和设备在解决蜂窝纸板生产中出现的问题方面具有较好的应用价值，同时对蜂窝纸板的研究提供参考。
[Abstract]:Since joining the WTO , China ' s import and export trade has become more and more active . At the same time , China ' s packaging industry has made a new challenge to China ' s packaging industry .

Based on the influence of process equipment on the mechanical properties of paperboard , the problems existing in the existing process equipment were analyzed . In order to produce honeycomb paperboard with different pore sizes , a series of spare rubber - coated rollers were designed .
