一、采用椭圆齿轮的优点 随着各种商品工业化生产规模的不断扩大与效率的提高,各种包装机的包装速度也越来越快。这就要求包装机上的各执行机构能在高速下准确地实现预定的动作。在种类繁多的各种包装机中,采用卷筒式包装材料对被包物品裹封成一纵两横封口的“枕式袋”包装机是一类典型的包装机。在这种类型的包装机上其包装速度的提高主要取决于包装袋端部(横向)封接速度的快慢(带定商标图案位置的包装袋其包装机包装速度亦在
First, the advantages of the use of oval gear With the continuous expansion of the scale of industrialization of production of various commodities and the improvement of efficiency, packaging speed of various packaging machines is also faster and faster. This requires that each actuator on the packaging machine can accurately achieve the intended action at high speed. Among a wide variety of packaging machines, the “pillow bag” wrapping machine that wraps the wrapped articles into a vertical and horizontal cross-hatch is a typical type of wrapping machine. The speed of packaging on this type of packaging machine depends mainly on the speed of the closure (transverse) closure of the package (the package with the trademarked pattern is also packed at a speed of
