【摘要】 高速接缝式自动包装机是实现薄膜材料裹包块状物品的一种包装设备，广泛应用于食品、化工、日用品、医药、小五金等部门。随着人们对包装的需求多样化、个性化，高速接缝式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，因此针对高速接缝式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、应用范围广的包装机是很有必要的。 本文在分析高速接缝式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、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；对供送薄膜结构、中封牵引器结构、端封切断器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和设计；本文对零部件建模，通过构建的运动模型，分析各机构的运动学规律，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。 本文研究了补偿原理、补偿结构，设计出中封牵引薄膜的补偿装置：采用齿轮差动补偿机构，可提高包装机的可靠性；提出适应包装袋长度可连续变化的机构，可扩大包装机的包装规格和使用范围；优化端封切断回转变速机构，实现了包装机的多功能；本文研究对其它袋装包装机械的设计和开发有着积极的指导意义。 本文设计电气控制系统满足变速、补偿、温度的控制：选用变频调速，使包装产量扩大并可调；本文独创的薄膜供送同步控制方式，简化控制电路，使包装机的牵引薄膜补偿更为可靠；温度控制方面，采用了先进的多路控制，使热封温度更适宜薄膜的封合。控制系统和机械结构相结合，使包装机满足高速、可靠、多功能要求。 本文借助了Visual Basic.Net,Inventor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。更多还原

【Abstract】 The high-speed automatic seaming packer can pack the nubbly products with film, especially used in the area such as foods, chemical products, commodity, medicine, hardware etc. With the requirements of the product packaging is more and more varieties and individuation, the high-speed automatic seaming packer is used more and more prevailing. As present, the most machines of our country copy the imported ones simply. So, in-depth research of the key parts, analysis of the principles, structures, movements and functions, and offer the high-speed automatic seaming packer which has simple and stable structure, more convenient operation, higher automatic level and wider the usage, it is very necessary.Through analyzes the packing techniques, using requirements and the principles of the key part of the high-speed automatic seaming packer, this paper offered an applied, simple, stable and universal driving system which using a new structure form that can adjust the packaging length and the output instead of the single packaging size. In this paper, design principles and structure characteristics of the key parts such as film feeding structure, mid-seem driving structure, end-seem cutter structure have been researched and designed in detail. In this paper, through builing the moving, analyzes the kinematics disciplinarian of the every organ and offers the feasible optimizing structure to meet the packaging technology needs. At the same time, this paper offers an integrated design method to the key parts.This paper designs a mid-seem film driving compensatory device through research the compensatory principles and the compensatory structures. Analyzing a gearing differential compensatory organ can help to increase the reliability of the packaging machines. Through offers a structure that can adapt the change of length and an end-seem cutting swivel shifting structure, makes the multi-function of the packaging machine come true. Integrating the electric control system, this paper offers a driving system structure which can adapt the change of the packaging bag length andcan direct the design and exploitation of other bag packaging machine actively.This paper designs the electric control system can meet the needs of the speed-shifting, compensatory and temperature control. Using frequency inverter can enlarge and adjust the packaging output. The feeding film synchronous control manner that is this paper original research can simple the control circuit and make the feeding film compensatory more reliable. On the temperature control, this paper adapts advanced multiplexing control, which can make the seal temperature more adapt to the film seal. This paper offers a high-speed, reliable, multi-function packaging machine.This paper analysis the moving disciplinarian and structure design using Visual Basic.Net, Inventor software, etc. This method that using computer aided design and analysis can apply to other packaging machine’s design and analysis.更多还原
