摘 要

随着改革开放进程的不断发展，我们的生活感受到了越来越多的科学技术革新，这些革新也越来越影响我们的生活，尤其是体现在生产工业中。现在人们越来越关注的则是包装工业。商品外包装的美观大方刺激着人们消费的效果，所以设计的题目是“扭结式糖果包装机设计”。

设计的基本方案是：在机器上完成双层糖纸裹包；总体布局是双端扭结，间歇式形式作业。与此同时，因为要求要大量生产糖果，故对于包装机来说就要求扭结动作较多，因此采用多工位裹包机。

该扭结式糖果包装机由传送机构、理糖机构、推糖机构、折纸机构、供纸结构、切纸结构、纽结结构、工序盘等几部分组成。机器进行作业时将待包装的硬块糖装进上料部分，然后在传送部分上进行裹包，同时剪纸切纸机构一起工作，最后由打糖杆打下机构。整体是用输送带对完成的包装糖果进行运输。

在设计的过程中，着重设计的是剪纸机构以及纽结结构。

关键词：裹包；剪纸机构；双端纽结；

Abstract

Nowadays, with the development of science technology, human’s life is more and more influenced by high-technology, especially in the production industry. Today, people pay more attention to packaging industry. The beauty of product packaging stimulates the effect of people’s consumption. The title of this design is “the design of the kink type candy packing machine”.

The basic design proposal is finishing double candy packing on machine; the overall layout is double end kink and intermittent form operation. At the same time, because of the huge requirement of candy production batch, multi station wrapping machine is more used.

This kink candy packing machine consists of transport mechanism, sugar processing mechanism, sugar pushing mechanism, folding mechanism, paper feeding mechanism, cutting mechanism, kink mechanism and working procedure. When machine operating, packing lump sugar will be put into feeding part, and then be wrapped in the transfer section. Paper cutting mechanism works with it at the same time. Finally, the mechanism is struck by sugar bar.

In the process of design, this design focuss on paper cutting mechanism and kink structure.

Key Words: Wrap; Paper cutting mechanism; Double end kink
