基于容积可变新型纸容器侧封装置凸轮机构设计

针对一种新型侧壁折叠窝进式容积可变包装容器的结构，根据设计的侧封装置，设计凸轮机构运动，分析凸轮轮廓线。根据新型可变容积包装容器的特殊结构特征，结合侧封装置方案，以抱合成型为主要实现方式，分析从动件运动轨迹，绘制凸轮轮廓线，得出所需凸轮机构。获得的凸轮机构较为精简，运动合理，可用于实现预先设计的侧封操作，推进实际生产。

Cam Mechanism Design of Side Sealing Device about Volume Variable New Paper Container

According to the side sealing device of a new side wall folded inward volume variable packaging container, this paper designed the cam mechanism and analyzed the cam contour line. According to the special structural characteristics of the new variable volume packaging container, combined with the side sealing device scheme, forming hugging as the main realization way,the follower motion trajectory was analyzed and the cam contour line was drawn, the required cam mechanism was obtained. The cam mechanism is more compact and reasonable, can be used to realize the predesigned side sealing operation and conduct the actual production.
