设计简介
摘 要
包装机械是包装工业的一大门类产品，在包装行业内占有举足轻重的地位，开发潜力巨大，有着很大的发展空间。咖啡粉枕式包装机是实现咖啡粉销售包装的主要机械工具。包装机械工具的使用不仅体现了现代生产的发展方向，同时也是提高经济效益的重要途径。进入21世纪，包装机械除继续增加新品种外，在产品的技术水平、内在质量和性能等方面都有了很大进步，这一切都与包装机械的设计有着密切的联系。在商品流通中人们对小袋商品的包装提出了越来越高的要求,不仅要求包装美观、便于运输、储存、使用方便和产品保质,而且要求包装袋内的商品计量准确,误差小。
本设计的内容为咖啡粉枕式包装机，主要应用CAD绘图软件进行咖啡粉包装机参数化的设计,具体任务是进行总体设计、横封切断装置设计。需要解决的问题主要有:根据包装袋的形状、尺寸、袋内咖啡粉的体积、封边方式的要求完成包装袋封口位置、装料位置；成形器、纵封棍等部件先后位置的确定。
本课题的设计意义及价值：所设计的设备应能满足咖啡粉包装要求，保证包装膜对正，便于调整，结构简单、运转平稳，工作可靠，便于维修。

Abstract
The packaging machinery is a door products in the packaging industry occupies a pivotal position in the packaging industry, tremendous potential for development, with much room for development. The coffee powder pillow packaging machine sales of coffee powder packaging machine tools. The use of packaging machinery and tools not only reflects the direction of development of modern production, but also an important way of improving economic efficiency. The 21st century, packaging machinery in addition to continue to add new varieties have a lot of progress in terms of technological level of products, the inherent quality and performance, all these are closely linked [2] and the design of the packaging machinery. People pouch packaging of goods in the circulation of commodities, the ever-increasing demands, not only require the packaging beautiful, easy to transport, storage, easy to use, and product shelf life, but also require accurate measurement of goods in the packaging bag, and the error is small.
The design pillow packing machine for coffee powder, the main application CAD mapping software for parametric design of the coffee powder packaging machine, the specific task of the overall design, the metering device and the horizontal seal cut-off device design. Need to be resolved to complete the sealing of the bags: bags of shapes, sizes, bags of coffee powder size, edge banding pattern of the loading position and form of metering device selection; shaper, pulling the stick, vertical seal sticks and other components has to determine the location.
Design significance and value of the subject: the design of equipment should be able to meet the packaging requirements of the coffee powder to ensure that packaging films are easy to adjust, simple structure, stable operation, reliable, easy to repair.
