文档介绍：I 摘要食品包装机械,是指能够完成全部或部分的产品和食品包装过程的机械,包装的过程有填充物料、裹包、封口等主要工序,以及与之相关联的前后工序,如清洗、堆码等。此外,包装还包含计量或在包装件上盖印等工序。使用机械包装的产品可提高生产效率,减轻劳动的强度,适应大规模生产需要,且满足清洁卫生要求。目前国内生产的设备大多是对国外进口设备的简单仿制,同时我国的包装机械产品也普遍存在质量的不好、性能单一、成本较高、技术含量较低的状况。因此对食品自动包装机械关键部件的深入研究,对原理、功能、结构、运动等分析,提供结构简单可靠、自动化程度高、操作方便、用途范围广的包装机很有必要的。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机构,工作原理及各组成部分功能做了较为详细的研究和设计,对关键部分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 UG 、 CAD 等软件分析运动规律和结构设计,这种利用计算机辅助设计和分析的方法,可以应用与其它类型包装设备的设计和分析中。关键词: 包装机械;封切机构;包装工艺;机构设计 II Abstract Food packaging machinery is able plete allor part of the products and food packing process machinery, packaging process, including filling, wrapping, sealing and other major process, and the associated processes before and after, such as cleaning, stacking, and demolition. In addition, the packaging also includes a measurement oron the package stamped and other process. The 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 hygiene, at present , domestic equipment is mostly a simple imitation of the imported product. Also, prevalence of inconsistent quality, and performance ofa single, high cost, low technical content and packaging machinery products in China situation. Therefore, 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 machine s
