所谓包装机械就离不开机械运动。机械运动的形式是多种多样的。其中有许多机构要作连续运动,如连续的转动或移动,连续的往复摆动和往复移动,这些运动形式可用齿轮机构、连杆机构和凸轮机构来实现。同时还有一些机构要作间歇运动,如:转位凸轮机构、马尔他机构、棘轮机构、欠齿齿轮机构等等。 The so-called packaging machinery can not do without mechanical movement. The form of mechanical movement is varied. Many of these mechanisms are used for continuous motion, such as continuous rotation or movement, continuous reciprocation and reciprocation, which can be accomplished with gear, linkage and cam mechanisms. At the same time there are some institutions to make intermittent exercise, such as: indexing cam agencies, Maltese institutions, ratchet institutions, under-gear institutions and so on.
