6、1.将铝箔纸覆盖在巧克力糖小端正上方；2.使铝箔纸沿糖块锥面强迫成形；3.将余下的铝箔纸分半，先后向大端面上褶去，迫使包装纸紧贴巧克力糖。2.原始数据及设计要求1.铝箔纸尺寸为64mm*64mm。2.巧克力糖小端直径17mm,大端直径24mm,,高12mm。3.生产率为60块/min。4.锥面成型机构不论采用平面连杆机构，凸轮机构或者其他常用机构，要求成形工作尽量等速，启动与停顿时冲击小。5.电动机转速为960/min.3.设计方案提示1.剪纸与供纸动作连续完成。2.铝箔纸锥面成形机构一般可采用凸轮机构，平面连杆机构等。3.实现折纸动作的机构有多种选择

7、，包括凸轮机构、摩擦滚轮机构等。4.巧克力糖果的送推料机构可采用平面连杆机构或凸轮机构。4.设计任务1.执行机构选型与设计：构思出至少3钟运动方案，并在说明书中画出运动方案草图，经过所有运动方案警醒分析评价后，选择其中的最优方案进行详细的设计。2.机构运动协调设计:对选择的方案画出机构运动循环图。3.传动系统的设计。4.对系统运动方案进行机构的尺寸综合。5.用UG软件对机构系统进行运动仿真。6.用UG软件对机构系统进行运动学分析，并画出输出机构的位移、速度和加速度线图。7.画出最终方案的机构运动简图。115.包装方案的拟定二．巧克力糖包装机的工艺确定1

8、.产品特征粒装巧克力糖呈圆台形，轮廓清楚，但质地疏松，容易碰伤。因此，考虑机械动作时应适合它的
