盒装饼干商标纸裹包机总体方案及传动系统的毕业设计.doc

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。 关键词：包装机械 ，裹包机，传动，商标 ABSTRACT Packaging machinery in the packaging industry plays an important role in the packaging industry modernization, play a decisive role, it can enhance productivity, improve the production environment, reducing production costs, improve product quality, increase the added value of products, thereby enhancing the market competitiveness, to bring greater social and economic benefits. With the development of science and technology, all kinds of food to appear ceaselessly, the food packaging technology and equipment are put forward new requirements, the design for the box cookies trademark paper wrapping machine overall plan and the transmission system design, puts forward a practical, simple and reliable transmission system, in the original basis of speed, the quality of packaging greatly increase. Out complex, redundant transmission parts, the original transmission system is simplified, with a single motor drive, Sifu motor control feed roller stop time and conveyor speed, thereby submitting transmission efficiency, saves the manufacturing and production cost. As far as possible the execution unit together, thereby reducing the overall dimensions of the machine. Close by a gear, belt wheel and chain transmission distance using. In the mechanical structure, this paper focuses on the supporting box board mechanism and a cam are the two important parts of research and design, the use of Matlab software analysis and design of cam contour shape;, because most of the a
