《灌装机的拨瓶机构的设计》-毕业论文设计（学术).doc

潍坊学院本科毕业设计 摘要 本文提出了一种灌装机的拨瓶机构的设计方案，并用变频器实现变速功能，从而达到方便使用的目的。 首先，要进行的是机械部分的设计。根据实际生产要求计算本系统所需要的转速及功率，动力通过转台系的芯轴输入，芯轴通过键将动力传给转台，转台上面既是灌装机的机头。拨瓶系与转台通过1 :1一对齿轮相连，使机头与拨瓶系同步相连吻合。 然后，根据变频调速三相异步电动机的电磁设计特点和结构特点，针对实际生产所需的不同转速，对电动机的转速，功率等各项参数进行计算，三相异步电动机实际上是灌装机拨瓶机构速度控制系统的执行部分，进而设计出根据不同生产情况实现变速的灌装机拨瓶驱动系统。 该系统具有操作方便，运行可靠，成本低，自动化程度高等优点，所以对灌装机的研发具有一定的参考意义。 关键词：灌装机 拨瓶 电机 变频器 单片机 ABSTRACT This paper gives a scheme for the system of a revolving stage,and we change rorate speed in transducer.so as to achieve the purpose of convenient and practical. First,the part of the mechanic should be designed.On the basis of the practical desire,we calculate the velocity and the power which the system need.The motivate is introduced by the shaft of the revolving stage. Following the motivate is introuduced to the revolving stage by a key,on which is the power of the filling machine.And the both main system are meshed by two gears that has the same size but different appearance.So the prow and the moving wheel can keep the same pace. By the design and structure characteristics of variable-frequency adjustable-speed three-phase induction motors,and we adapt the transducer to adapt some parameters such as the rotate speed and the power of the electromotor by analyzing the power of the total system.Three-phase asynchronous motor is actually the controlling system operative system of the speed of about filling machine turntable.By this we choose the right electromotor.So we select the transducer to adapt the different speed of capper turntable machinery and the drive system.
