ABSTRACT The packing machinery is one of national economy importantindustrial,undertakes the lives of the people, is prospering the cityandcountryside market, expanded exportation bringing in foreign exchangeincome,for the national construction accumulated capital importanttask, to promotesthe national economy coordinated development andrealizes the overall strategictarget relations which the nationaleconomy and the society develops to beextremely close. Since thereform and open policy, our country packingprofession has obtainedthe considerable development, the appearance has had thehuge change,already forms has the suitable scale and the certainlyeconomicallevel, the class is complete, can basically satisfy thedomesticdemand also to have the certainly international competition abilitytheproduction system. May say like this has not packed the machinerythedevelopment not to have the diverse product which today prospers. Takeelectronic technology, computer technology and so on asrepresentative's high-techswift and violent development, not onlyurged national's living standard toenhance day by day, as well as theproduct turned to a new generation cyclicalreducing, moreover causedthe mechanical product the performance unceasingenhancement and theconsummation. This especially in the packing mechanicalaspect, thecommodity life enhancement already could not meet people's needs,whatnow are more was advocates the spiritual civilization the wealth. Thepeoplehave not liked 80's such only to strive for to fill the belly,how do we now paygreat attention to pursuing each kind of food thehygiene condition? Whetherfacilitates quickly? Also some point alsois most important - food outsidewrapping. Ancient cloud: "Beautifulenough to eat". Said with thepresent popular speech that, "Saw thefood attractive outside wrapping cancause person's mood to be happy,thus causes the appetite also to be able toincrease." This oursubject pulled closer is away from. Now the market usesmost packingtype is trilateral seals the bag which seals with the center. copyright paper51.com 第一章 绪论 http://www.paper51.com 1.1包装机械的地位与现状 http://www.paper51.com 包装机械是国民经济的重要产业之一，承担着人民生活、繁荣城乡市场、扩大出口创汇、为国家建设积累资金的重要任务，对促进国民经济协调发展和实现国民经济与社会发展的总体战略目标关系极为密切。改革开放以来，我国包装行业得到了长足的发展，面貌发生了巨大的变化，已经形成有相当规模和一定经济水平、门类齐全、能基本满足国内需求又有一定国际竞争能力的生产体系。可以这样说没有包装机械的发展就没有今天繁荣的多样化的产品。 内容来自www.paper51.com
以电子技术、计算机技术等为代表的高新技术的迅猛发展，不仅促使了国民的生活水平日益提高，以及产品升级换代周期的缩短，而且使得机械产品的性能不断的提高与完善。这尤其在包装机械方面，物资生活的提高已经不能满足人们的需要，现在更多的是提倡精神文明的富有。人们已不像八十年代那样只求填饱肚子，我们现在更注重于追求各种食品的卫生状况怎样？是否方便快捷？还有一点也是最重要的一点——食品的外包装。古人云：“秀色可餐”。用现在通俗一点话来说：“看到食品漂亮的外包装会使人的心情愉快，从而使得食欲也会增加的。”这就我们的主题拉近距离了。现在市场用的最多包装类型就是三边封和中封的袋子。 内容来自论文无忧网 www.paper51.com 1.2包装机械的任务和特点 paper51.com 1.2.1包装机械的任务 paper51.com 当今包装制袋机有好几十种但主要有以下几种， http://www.paper51.com 例如1 . 专用三边封低速,中速,高速三种制袋机. copyright paper51.com
2 . 专用中封低速,中速,高速三种制袋机. http://www.paper51.com 3 . 三边封,中封两用低速,中速,高速三种制袋机. 内容来自论文无忧网 www.paper51.com 4 . 高速三边封的自立,拉链制袋机. paper51.com 5 . 医药特用制袋机. http://www.paper51.com
因此包装机械是轻工业发展的基础和动力，它是实现我国社会主义现代化，满足人民不断增长的物质和文化生活需要，建设高度的物质文明与精神文明的社会主义所不可缺少的重要装备。 http://www.paper51.com 1.2.2包装机械的特点 paper51.com 1品种多三边封、中封、拉链袋、有吸嘴的那种等一系列的，这主要是因为加工材料的多样化。 copyright paper51.com 2生产率高，自动化程度高。 内容来自论文无忧网 www.paper51.com
这是因为人民日常生活的迫切要求，必须大量大批生产各类包装产品，需要高生产率、高自动化程度的包装机械，3000个/小时的包装袋的流水线上。 内容来自www.paper51.com 3机构和动作复杂 内容来自www.paper51.com
这是因为包装机械生产的工艺原理和工艺过程比较复杂。包装机械受力一般不是很大，因此强度计算不是很重要。 paper51.com 1.3包装机械的分类 paper51.com 1.3.1包装机械按速度分类 copyright paper51.com 有底、中、高三速的包装机，它们是分别根据每小时能生产出来袋子的数量来分的。 http://www.paper51.com
