近半个多世纪以来，随着生产与流通日益社会化、现代化，产品包装正以崭新的面貌崛起，受到人们普遍重视。
本设计主要目的是实现酸菜加工的自动化。其间介绍了灌装机的概念、种类。主要是针对酸菜自动包装生产线注液系统进行的设计主要通过对机械设计的学习、了解和掌握，来确定酸菜自动包装生产线注液系统的各个组成零件并最后组装。通过计算和结构优化设计，决定采用气泵为动力源，以气缸的往复运动及两个单向阀的反向安装来实现酸菜自动包装生产线注液系统的吸液和注液，从而实现由比较简单的结构完成要求的目的。
设计后的酸菜自动包装生产线注液系统具有结构简单、紧凑、制造和维修容易、操作简单，成本低。广泛用于中小型食品生产企业。

ABSTRACT

With the socialization and modernization of the production and circulation since more than half a century，products packing is flourishing with a completely new feature and attached importance widely.
The main purpose of this design is to realize the automatization of acid vegetable processing. It introduces the conception and category of the filling machine. The design aims at the infusing liquid system of the product line of acid vegetable automatic packing. We confirm every part of the system and install it according to the study of machinical design. We decide to use the air pump as the power fountain and realize sucking liquid and infusing liquid by the reciprocating of air urn and the reversed setting of two mon-return valves after calculating.Consequently，we achieve the purpose with a more simple configuration.
The infusing liquid system of the product line of acid vegetable automatic packing have simple configuration，. It is tighten and easy to produce， mend and handle .Also it cost low .It is widely used in small and middle food manufactories.

Key word: air pump；air urn；mon-return valve；eleceromagnetism cross valve；limit switch；stores the fluid cylinder；auto control
