基于单片机的粉料包装机控制系统设计

摘 要

粉料自动包装机是实现薄膜材料包装粮食等粉料产品的一种包装设备，广泛应用于食品、化工、医药、小五金等生产包装部门。随着人们对包装的需求多样化、人性化，粉料自动包装机的应用愈加普遍。目前国产的设备大多是对国外进口产品的简单仿制，因此针对粉料自动包装机关键部分的深入研究，对原理、结构、运动、功能等分析，提供结构简单可靠、操作方便、自动化程度高、使用范围广的包装机很有必要。

本文在粉料自动包装机的包装工艺和使用要求的基础上，通过对关键部件的理论分析，提出一种使用简单、可靠和通用的传动系统，将单一包装尺寸拓展为袋长和产量可调的结构形式；对包装袋制造结构、装袋封口结构、传送结构等关键部件的设计原理、结构特点等做了较为详细的研究设计；本文分析各种机构的运动学规律，提出可行的优化结构满足包装工艺；对关键部件提出完整的设计方法，旨在满足市场需求，推动企业创新步伐。

本文借助了AutoCAD、protel-DXP、Microsoft Office Visio、keli等软件进行原理图绘制，流程图绘制，编写程序等。这种利用计算机作辅助设计和分析的方法，可以用于其他类型包装机设备的设计和分析中。

Design of Automatic Powder Material Packaging Machine Based

on MCU

ABSTRACT

Powder automatic packing machine is the realization of thin film materials such as packaging of food products as a powder packaging equipment, widely used food, chemical, daily necessities, medicine, hardware and other departments. As the demand for packaging diversification, personalization, automatic powder packaging machine applications more generally. Most of the current China-made equipment is Simple import of imitation products,the automatic packing machine for powder-depth study of key components, the basic principles, structure, movement, functional analysis, to provide a simple and reliable structure, convenient operation, high degree of automation with a wide range of packaging machines is necessary.

Based on the analysis of powder packing machine automatic packaging processes and the use of the requirements on the basis of the key components of the theoretical analysis, a practical, simple, reliable and versatile drive system, a single package for the bag to expand the size and output of long adjustable structure, for delivery of the film structure, the structure of closed traction, closed-end structure, such as cutting off key parts of the design principles, structural features, such as doing a more detailed study and design,This paper analyzes the law of the Kinematics , optimizing the structure and put forward feasible to meet the packaging process,a key component of a complete design method, designed to meet the market demand, Promoting innovation.

In this paper, using the autocad, pro-e, such as movement of software analysis and structural design, such as the use of computer-aided design and analysis methods can be applied to other types of packaging equipment design and analysis.

KEYWORDS:automatic,packingmachine ,packing sealing system,weighing system，Counting display system
