机械毕业设计595定量泵式灌装机设计说明书解析

摘要

当前，在制药包装机械领域内，小容量液体灌装机发展缓慢，在大产量分包装作业中，高速灌装机基本上是进口机器。目前，国内机器可在灌装计量方式、生产效率、机器的运转稳定性、表面处理、电器元件选型方面进行研发，消化吸收国外厂家的先进技术，作为重点开发方向。设备整机设计应简洁流畅，外部零件光滑，无毛刺，经倒角或圆角处理，便于清洁。灌装机的工作面应尽可能简洁或架空，以减少洁净空气阻力，提高层流效果。设备应用层流罩罩住，层流罩门开启应有报警装置，操作人员在灌装机工作时，尽量不接触或者少接触机器上任何零部件。设备上应有手持开关，可以点动机器，或者联动机器。在缺塞时整机停机，无瓶不灌装，电磁振荡器送塞顺畅自如，震荡功率可调整。主机具无级调速、计数装置、倒瓶剔除、剔除空瓶功能。可选择在线秤重功能。在自动控制方面，使用并行总线采集和输出信号，可编程控制器处理信号，带通讯接口，通过人机界面监测运行状况，可在线修改运行参数。

现在的高速灌装机的灌装运行方式一般是排列成直线式或者是旋转式

跟踪多头灌装，加塞机构一般都采用真空吸塞，直线式加塞，而且主机都可以无级调速。小容量液体灌装机器还有互换性要求，要求机器在很短的时间内，更换最少的规格件，就可以使2ml，5ml,7ml, l0ml管制瓶一台机器上完成灌装加塞，而直线式灌装机可以满足互换性的要求。

目前国内在积极地开发恒压控制技术，但这种技术开发难度大，主要是自动控制技术不成熟，而且开发研制的前期投入高，开发人才匾乏，限制了时间压力法的推广应用。因此，金属/陶瓷活塞泵计量灌装法是目前国内药机重点开发的技术，其市场风险较小，也是应重点推广的技术。

本课题在现有定量泵式灌装机的基础上，设计出一种更适合小型化妆品企业食品包装的定量泵式灌装机。作者首先针对定量泵式灌装机的发展现状提出了设计方案，其次进行了总体结构设计、典型零件的设计与校核及对轴的加工工艺的概述，最后分析了定量泵式灌装机的经济效益。

Abstract

At present, in the field of pharmaceutical packaging machinery, small volume of liquid filling machine development has been slow and in the production sub -Packaging operations, high-speed filling machine is basically imported machines. At present, the domestic machine can be measured in filling , Production efficiency and stability of the operation of machinery, surface treatment, electrical component selection aspects of research and development, digestion and absorption of foreign advanced technology manufacturers, as a key development direction. Whole machining equipment design should be simple smooth, External components smooth, burr, the chamfering or fillet with easy cleaning. The face should be filling machine May be simple or elevated, to reduce the clean air resistance and improve laminar flow effect. Application equipment laminar flow hood enclosures Live, laminar flow Zhaomen alarm device should be opened, the filling machine operators work, try not to contact or Less contact with any machine parts. Handheld devices should switch, you can move the machines, or linked machine For. Cypriot missing in the stands when whole machine, no bottle is not filling, sending electromagnetic oscillator Cypriot smooth ease, power adjustable shocks. Host a stepless speed regulation, counting devices, inverted bottles removed, remove empty bottles feature. Online weighing the option function. In automatic control, collection and use of parallel bus output signal, the PLC signal processing, interface with communications through the operation of monitoring human-computer interface can be modified on-line operating parameters.

On the basis of the fix quantify pump filling machine, the issue designs a fix quantify pump filling for the combination of bottled beer. The author first point out the design program against the research status of the fix quantify pump filling machine, followed by a general structural design, the design and verification of typical components and the outlines of the axis machining process , finally analysis of economic benefits of the fix quantify pump filling machine.

Keywords:fix quantify packaging，filling machine, press filling , structural design
