碎纸机是用切割方法销毁机密或者牵涉隐私文件材料的事务机器。电动碎纸机切割出来的形状主要有长条状、短条状、粒状等。一般说来，切割的碎片越小，别人从碎片拼凑出内容的可能性越低。为了加强保密，切割的方向应该和文字的书写方向垂直，而且碎片在丢弃之前要分散打乱，否则碎纸机切割过的文件经过努力可能被复原出来。

通过本设计，使学生在一些简单的机械结构上得到启发，获得对机械设计的制造灵感，并及时补充相关的知识，通过对机械传动结构的深度剖析以及机械部件的装配等步骤，提高学生解决实际问题的能力，同时熟练掌握专业相关的操作工具，锻炼学生的自己动手能力，从而达到手脑眼相互协作的目的，为以后工作打下基础。  

 

 

Abstract

    A shredder is a transaction machine that uses a cutting method to destroy confidential or material that involves privacy documents. Electric shredders cut out the shape of the main strip, short strip, granular and so on. In general, the smaller the number of cut pieces, the lower the likelihood that others will spell out the content from the pieces. In order to strengthen confidentiality, the direction of cutting should be perpendicular to the writing direction of the text, and the pieces should be disrupted before being discarded, otherwise the paper cut by the shredder may be restored.

    Through this design, students in some simple mechanical structure inspired, access to the mechanical design of the manufacturing inspiration, and timely supplement the relevant knowledge, through the mechanical transmission structure of the depth of analysis and mechanical components such as assembly steps to improve students to solve Practical problems, while proficient in professional management tools, exercise their own hands-on ability, so as to achieve the purpose of mutual cooperation between the mind and brain, lay the foundation for future work.
