第二章 传动装g of goods in the circulation of commodities, the ever-increasing demands, require not only the packaging beautiful, easy to transport, storage, easy to use, and product shelf life, and requires accurate measurement of the packaging bag of goods, the error is small. "Measurement" is an important part of the packaging process, the accurate measurement of packaging is an important topic to always pay attention to the packaging industry.
The design pillow packing machine for coffee powder, the main application CAXA 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; cross-head and the design of the feeding device.
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.
Key Words:Packaging Machinery; Coffee powder packaging machine; CAXA
第一章 咖啡粉枕式包装机总体设计
咖啡粉枕式包装机的包装原理： 咖啡粉枕式包装机整体是由几个机构组成，主要有：料盘装置，横封装置，竖封装置，走袋装置，料卷装置，电机等通过一定的传动关系组成
[4]。塑料薄膜卷在料卷装置上通过成型器成型形成卷筒状然后通过竖封装置热封，再通过牵引机构向前走袋，在走袋的过程中料盘装置把计量好的咖啡粉通过料斗注入竖封好的袋中，最后通过横封机构横封切断，包装完成。根据包装机的要求，在包装过程中要确保各个装置之间运动协调。
传动方案要满足工作可靠、结构简单、尺寸紧凑、传动效率、使用维护便利、工艺和经济性好等要求。
经过分析与比较,决定采用如下运动方式：电动机带动V带轮转动,经过蜗杆蜗轮减速带动凸轮轴转动，然后一局部动力通过用同步带轴，同步带轴通过一对齿轮把动力传给料盘轴。用蜗杆蜗轮减速是因为它的传动比大可以一次将转速降到需要的大小，使结构简单；用一根轴同时带动横封机构、竖封机构、走带机构既能使结构简单又能保证三者之间同时协调的工作；用同步带传动既能保证准确的传动比又能实现较大中心距的传动。整个机构结构紧凑，传动平稳，
