中文摘要:

      目的 研究锁底结构形式对纸盒承载力的影响。 方法 选取 3 种常用的锁底结构( 插口式、1-2-3 锁底式、典型自锁底式) 进行压缩试验和跌落试验。 结果 进行压缩试验时,插口式盒底被破坏时仪器显示的峰值为 31 . 2 N;压缩试验无法破坏后 2 种锁底结构,因此采用跌落实验,获知 1-2-3 锁底式被破坏时砝码质量为 180 g,典型自锁底式被破坏时砝码质量为 205 g。 结论 综合比较得知,相较于插口式,典型自锁底结构和 1-2-3 锁底结构的纸盒承载力优势明显,典型自锁底结构表现最强。

英文摘要:

      Objective To explore the effects of the bottom lock structure on the carrying capacity of the folding carton. Methods Three commonly used bottom lock structures ( sockets style, 1-2-3 bottom lock structure, bottom self-locking structure) were selected for compression test and drop test. Results The socket-type bottom of the box was damaged when the instrument displayed a peak of 31. 2 N during the compression test; the tensile testing machine could not destroy the latter two lock bottom structures. In the drop test, the weight of code was 180 g when the 1-2-3 bottom lock structure was damaged, and the number was 205 g when the bottom self-locking structure was damaged. Conclusion The comprehensive comparison showed that, compared to socket style, the bottom self-locking structure and the 1-2-3 bottom lock structure had obvious advantages in carrying capacity, and the bottom self-locking structure had the best performance. And an appropriate locking style could improve the capacity of sockets style.
