鸡蛋安全快递包装结构设计

目的设计一种适用于小批量多批次运输的鸡蛋快递安全缓冲包装。方法通过经典的缓冲包装六步法,设计拉伸形式的缓冲结构,计算了缓冲垫的面积与厚度,对包装件进行了强度校核,并根据ISTA3A标准对包装件进行了跌落与随机振动试验,以验证包装件的缓冲效果。结果对5箱鸡蛋进行了不同面跌落、楞跌落和角跌落的3组重复测试,结果表明其破损率远远低于目前市场上的鸡蛋缓冲包装的破损率(10%),具有良好的保护效果;随机振动试验显示,缓冲包装中鸡蛋无一破损。结论该结构具有良好的缓冲性能,能保证鸡蛋在快递运输环境下得到有效保护,具有较好的应用前景。

Packaging Structural Design of Egg Safe Express

This paper aims to design a safe cushioning package for eggs express delivery, which is suitable for small batch and multi-batch transportation. In order to verify the cushioning effect of packages, the area and thickness of cushion pads were calculated by the classical six-step cushioning packaging method, and the stretching cushioning structure was made. The strength of packages was checked by the formula, and the drop and random vibration tests of packages were carried out according to ISTA 3A standard. The results of 3 groups of repeated tests on different falling faces, edges and angles of 5 boxes of eggs showed that the breakage rate was much lower than the 10% breakage rate of cushioning packages on the market, which had good protection effect. Random vibration test showed that there were no eggs in cushioning packages. Finally, it is concluded that the safe express packaging of eggs designed in this paper has good cushioning performance, can ensure that eggs are effectively protected under the transportation of express logistics. It has good application prospects.
