中文摘要 成型－充填－封口包装机是能够完成包装容器的成型，充填，封口的机器。而立式袋成型―充填―封口包装机是包装机械中应用最广泛，批量最大的机型之一，其特点是被包装材料的供料筒设置在制袋器内侧，制袋与充填物料由上到下沿竖直方向进行。该成型机器主要由计量装置，传动系统，横封和纵封装置，成型器，充填管及薄膜牵拉供送机构等部件组成。本次设计的包装机为枕型袋包装形式的液体立式成型－充填－封口包装机，选用万能枕型袋成型器，机械无级调速装置，高频加热式横封器，纵封器，牵拉滚轮通过传动，执行机构实现包装机的包装参数要求。 关键词包装机，计量装置，横封，纵封，牵拉滚轮，成型器，机械无级调速装置 Title Abstract: Shaped - filli
