燃气灶无纸箱热收缩保护性包装结构设计与评价

目的 为打破家电泡沫加纸箱的传统包装形式，大胆创新设计无纸箱小家电燃气灶的热收缩包装，并使用CAE分析方法评价该包装的缓冲性能。方法 根据燃气灶产品特性设计缓冲衬垫结构，以热收缩膜直接紧紧包裹产品和缓冲衬垫的包装形式为评价对象，用Pro/E完成产品建模，导入Ansys Workbench完成跌落仿真分析，最后进行实验评价。结果 仿真结果表明，最大加速度出现在5.6 ms处，最大值为14.86g，小于产品脆值，仿真结果合格；跌落实验后，缓冲衬垫轻微变形，产品完好无破损，该包装方案可行。结论 验证了燃气灶无纸箱的热收缩包装的可靠性，为后续小家电的无纸箱包装提供了新思路。

Structural Design and Evaluation of Box-free and Heat ShrinkableProtective Package for Gas Stoves

The work aims to break the traditional packaging form of household appliances foam with carton, make bold and innovative design of heat shrinkable packaging for small household appliance gas cooker without carton, and use CAE analysis method to evaluate the cushioning performance of the packaging. According to the characteristics of the gas stove product, the cushion structure was designed. The packaging form of the heat shrinkable film directly wrapping the product and the cushion pad was evaluated. The product model was completed with Pro/E, and the ANSYS Workbench was introduced to complete the drop simulation analysis. Finally, the experiment was carried out. The simulation results showed that the maximum acceleration occurred at 5.6 ms, the maximum value was 18.86g less than the product brittle value, and the simulation result was qualified. After the drop test, the cushion pad was deformed, and the product was intact without damage, so the packaging scheme was qualified. The feasibility of the heat shrinkable packaging of the gas stove without carton is verified, and the new ideas for the subsequent carton-free packaging of small household appliances are presented.
