摘要
包装机械在包装工业中的地位十分重要,对包装工业现代化具有举足轻重的地位,它可以提高生产率,改善生产环境,降低生产成本,提高商品档次,增加附加值,从而增强商品的市场竞争力,带来更大的社会效益和经济效益。
随着科学技术的不断发展,各种食品不断出现,对食品包装技术和设备都提出了新的要求,本设计针对盒装饼干商标纸裹包机的总体方案和传动体统的设计,提出一种实用、简单和可靠的传动系统,在原有的基础上将速度、包装质量大大提高。出去复杂、多余的传动部件,将原有的传动系统简化,用单一电动机带动,私服电机控制送纸辊的动停时间和输送速度,从而提交传动效率,节约制造和生产成本。尽可能将执行部件集中在一起,从而减小机器的整体尺寸。近距离采用齿轮传动,远距离采用带轮和链轮传动。在机械结构方面,本文重点对托盒板机构和凸轮这两个重要部件进行研究和设计,使用Matlab软件分析设计凸轮轮廓形状;,由于大部分执行机构是间歇式的,所以在推板,热封机构等均采用凸轮控制,从而设计一台高效、低耗、低成本、高质量的小型自动商标纸裹包机,从而满足市场对包装设备的需求。
