设计是关于食品的包装设备简称包装机的设计。包装机是将食品装入袋内，再封装。主要适用于小食品、医药产品的包装。它具有操作简单、生产量大、适用范围广等特点。 
包装机主要由几部分构成：引导成型部分、喂料部分、纵封牵引部分横封切割部分。塑料薄膜安装在退卷装置上，经过导辊的引导输送塑料薄膜在成型器的作用下形成袋状，这时纵封将袋封上纵向口，喂料装置下料，横封辊在将其封住横向开口，并且切断。至此一个包装袋形成。 
本文从基本理论、基本工作原理、基本分析方法上对设计作了阐述。在本次设计中采用了，滚轮纵封装置，整体加工式横封辊结构。 
滚轮纵封装置将以往的纵封和牵引合为一体，这样既节省了空间，又使整体更具有美观性。整体加工式横封辊结构将横封和切断装置合成一体，减少了封装时间。 
最后一个重要的部分是UG的建模、装配。Unigraphics(简称UG)是当前世界上最紧密集成和先进的、面向制造相关行业的CAD/CAE/CAM高端软件。作为一种集成的产品工程解决途径，UG软件使得用户能够数字化地获取和创建三维产品定义。UG软件成为当今世界领许多先进的制造商用来从事工业设计、详细的机械设计、概念设计以及数字化和更成仿真化的制造等各个领域。

Abstract

 
This paper is about the design of the packing equipments with small grain food which is call for grain packer. the grain packer is to pack the food of the small grain into the bag inside, then seal the bag. It is applicable to the packing of small food, medicine product primarily. It has the operation simple、produce have great capacity、apply wide etc. in scope characteristics.    
The grain packer is main from several parts of composingses: the part of the leading models and the part of feeding machine device, the part which vertical-seal and draught, and the part which horizontal-seal and cut down. The plastics thin film installs at equipment for withdraw the film, hasing been led the leading roller to molding machine, with which the film is form pockety, at this time vertical-seal seal the vertical caliber, feeding machine put the feed into the pockety, horizontal-seal seal the horizontal caliber, and cut off. Thus pockety is done.    
This paper makes to expatiate to the design from the basic theories, basic work principle, basic analysis method. Vertical-seal rolling device will be former seals with lead to match for integral whole, thus this device saved the space, and make the whole even have the beautiful again. Integer machining type horizontal-seal make the whole horizontal seal with the cut-off device synthesize the integral whole, reducing sealing-pack time.    
The last important part really is an UG to set up the molding and assemble. The Unigraphics (brief name UG) is current to enter first in the world with close gather of, face to the CAID/CAD/CAE/CAM that make the profession the high carrying the software. Be used Be used as a gathers of completely product engineering solution, the UG software household makes customer can the arithmetic figure turn the ground creates to set up with obtain three dimension product definition. This paper is detailed to introduced to set up axially the mold, wheel gear sets up the mold, and its assemble really imitate with the development.
