中文摘要:

      目的 设计一种能提高结构强度的复合式泡沫包装箱。方法 将由护边套和护板构成的护架套装在泡沫包装箱的外部, 组合成复合式泡沫包装箱, 通过静态压缩实验和跌落实验, 对比测试普通泡沫包装箱和复合式泡沫包装箱的抗压强度、抗破损性能。结果 复合式泡沫包装箱单体抗压强度1959.29 N, 普通泡沫包装箱单体抗压强度1557.22 N; 对于交错堆码条件下, 抗压强度由普通泡沫包装箱的1039.18 N提升到复合式泡沫包装箱的1978.56 N。采用护架后, 箱体载物面跌落破损高度由800 mm提高到1400 mm, 棱跌落破损高度由600 mm提高到1200 mm, 角跌落破损高度由400 mm提高到1000 mm。结论 采用护架的复合式泡沫包装箱, 提升了箱体结构强度、耐破损性能, 解决了多层堆码箱体压损问题, 降低了箱体的破损率, 提高了包装箱重复使用率。

英文摘要:

      Objective To design a composing foam packaging box that can improve strength of structure. Methods Putting the protective frame composed of the edge guard and the guard plate on the outside of the foam packing box, a composite foam packing box was formed. Through static compression experiment and drop experiment, the compressive strength and damage resistance performance of ordinary foam packaging boxes and composite foam packaging boxes were compared and tested. Results The compressive strength of a composing foam packing box was 1959.29 N, and the non-sheath foam packing box was 1557.22 N. Under the condition of staggered stacking, the compressive strength was increased from 1039.18 N of ordinary foam packing box to 1978.56 N of composite foam packing box. After adopting the protection frame, the falling damage height of the carrier surface of the box body is increased from 800 mm to 1400 mm, the falling damage height of the edge is increased from 600 mm to 1200 mm, and the falling damage height of the Angle is increased from 400 mm to 1000 mm. Conclusion The composite foam packaging box with protective frame improves the structural strength and damage resistance of the box body, solves the problem of pressure loss of multi-layer stacking boxes, reduces the damage rate of the box body, and increases the reuse rate of the box.
