摘　　要：本文主要介绍现代医药冻干机瓶装药物加塞系统控制的主要结构与工作原理。通过设计计算、实验研究得出最佳设计方案 ,为药用冻干机在进行可加塞瓶装药品中 ,提供了一个可借鉴的设计方案 ,并在实际制造工艺与药品生产工艺中取得了较好的效果。加塞系统的一个重点就是加塞行程的控制 ,即如何使搁板加塞完毕后即能停住。由于各层加塞是同时完成 ,所以通过活塞筒里活塞行程来控制搁板的行程。当活塞达到工作行程后 ,加塞也同时完成 ,就要停止液压泵的工作 ,也就是要对液压泵的进出油量实行控制。本文选用位移传感器来控制电路的实现 ,即液压泵控制电路。当达到规定位移时 ,位移传感器发出信号 ,通过控制电路使液压泵停止工作 ,则搁板和活塞都停止下移 。The main purpose of the thesis is to introduce the primary mechanism and principle of the adding stopper system of modern freeze drying machine for medicine. In this thesis, by experimentation and calculation, we gained a feasible design schema for the adding stopper system. Furthermore, we got the preferable effect in practical manufacture technology and medicine producing technology with this schema. The emphasis of the adding stopper system is the control of the moving of the shelf after the stoppers are added at the same time, the control of the shelf can be acquired by the piston in the piston canister . When the piston reaches the working distance, the stoppers are added at the same time, then the hydraulic pressure pump must be stopped, that is to control the oil quantity. In the thesis, the displacement sensor is chosen to control the circuit of the hydraulic the formulary place, the sensor send out a signal which make the pump stop through the control circuit, then the shelf and piston will stop moving, so the adding stopper system is controlled.
