精品毕业论文--包装机设计横封机构.doc

摘要
食品包装机械,是指能完成全部或部分产品和食品包装过程的机械。包装过程包括充填、裹包、封口等主要工序,以及与其相关的前后工序,如清洗、堆码和拆卸等。此外,包装还包括计量或在包装件上盖印等工序。使用机械包装产品可提高生产率,减轻劳动强度,适应大规模生产的需要,并满足清洁卫生的要求。目前国产的设备大多是对国外进口产品的简单仿制,并且我国的包装机械产品普遍存在质量不稳定、性能单一、成本高、技术含量低的状况。因此针对食品自动包装机关键部件的深入研究,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、用途范围广的包装机是很有必要的。
本文在分析方便面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,提出一种实用、简单的横封机构,实现了根据薄膜厚度不同自动调节加热时间和温度的功能,并且对方便面包装机封切机构的结构,工作原理及各组成部分功能做了较为详细的研究和设计,对关键部件提出完整的设计方法和造型设计,旨在满足市场需求,推动企业创新步伐。
本文借助了autocad,pro-e等软件分析运动规律和结构设计,这种利用计算机作辅助设计和分析的方法,可以应用于其它类型包装设备的设计和分析中。

ABSTRACT
Food packaging machinery is able plete all or part of the products and food packaging process process, including filling, wrapping, sealing and other major processes, and the associated processes before and after,Such as cleaning, stacking, and addition, the packaging also includes a measurement or on the package stamped and other use of mechanical packaging products to increase productivity, reduce labor intensity, to meet the needs of the large-scale production, and meet the requirements of present,Domestic equipment is mostly a simple imitation of the imported product,Also,Prevalence of inconsistent quality, and performance of a single, high cost, low technical content and packaging machinery products in China , in-depth study of the ponents of food-automatic packaging machine,the principle, structure, movement, functional analysis,Provide a simple and reliable structure, convenient operation, high degree of automation is necessary to use a wide range of packaging machines.
This article based on analysis of instant noodles, automatic packing machine packaging technology and use requirements,By means of the theoretical analysis of the ponents,Propose a practical, simple cross-seal mechanism,Realized the function automatically adjusts the heating time and temperature according to the film thickness,And instant noodles packaging machin
