一种异形多边形瓦楞纸箱的抗压性能研究

在传统瓦楞纸箱上增加了切角结构,以构成适用于衬垫外箱一体式快装包装箱的异形多边形瓦楞纸箱。通过试验研究了切角结构对纸箱抗压强度的影响,比较了不同切角尺寸、切角角度与切角数量对纸箱抗压强度的影响。结果表明:在其他结构参数保持不变的情况下,纸箱抗压强度在一定范围内随着切角长度的增加而增大;切角角度越接近45°,抗压强度越大;切角数量越多,抗压强度增加越明显。试验结果为该一体式快装包装箱的结构设计提供了理论依据,对利用切角提高纸箱抗压强度的结构设计也有一定参考价值。

Compressive Properties of an Irregular Polygonal Corrugated Box

Cutting angle structure was added to traditional corrugated carton to form irregular shaped polygonal carton, which can be suitable for integral fast packaging box of liner and outside box. The effect of cutting angle structure on the carton's compressive strength was studied through experiments, and the effects of cutting angle sizes, cutting angle, and the number of cutting angle on the carton's compressive strength was compared. The results showed that when other structural parameters remain unchanged, the cartons compressive strength enhances in a certain range with the increase of the length of the cutting angle; the cutting angle be closer to 45°, the compressive strength will be larger; the more cutting angle number, the more obviously compressive strength increased. The results of experiments provides a theoretical basis for structure design of integral fast packaging box, and also has reference value on structural design by using cutting angle to improve cartons compressive strength.
