中文摘要:
      目的 解决铝箔卷装盒机封口机构在工作过程中出现抖动和凸轮回位弹簧经常断裂的问题。方法 建立封口机构的虚拟样机模型并进行动力学仿真, 通过封口机构的动力学特性分析封口机构中凸轮轮廓、 回位弹簧刚度、 装盒速度对整个封口机构工作性能的影响。结果 仿真结果表明, 封口机构的抖动出现在封口机构封口完毕之前, 正准备进入保持阶段的时候。回位弹簧刚度有助于减缓封口机构的抖动, 但若继续增加刚度, 减缓抖动的效果不明显。结论 当凸轮回位弹簧的刚度为0.4 N/mm, 封口速度为2 盒/s时, 封口机构的抖动最小, 整个过程中无明显的冲击现象, 整机性能得到提升。
英文摘要:
      In order to reduce the vibration of the sealing mechanism of aluminum foil cartooning machine during the working process and solve the problem of cam return spring fracture, the dynamic characteristic of the sealing mechanism was analyzed by using Adams. The influence of the cam profile and the return spring stiffness was also analyzed. Besides, the effect of cartooning speed was also taken into account. As the simulation result showed that the vibration often appeared before the end of sealing process when the remaining stage was about to start. Increasing the return spring stiffness was helpful for mitigating the vibration, but the effect was not obvious when the return spring stiffness continued to increase. The impact phenomenon was not obvious and the sealing mechanism had a good performance when the return spring stiffness was 0.4 N/mm and the cartooning speed was 2 pcs/s.
