纸粉碎机的设计和制作|188金宝搏怎么样机械项目
抽象的：
在本文中,我们将讨论详细的螺栓y, design procedure and results of a paper shredder machine. A detailed study of various parts of shredder machine like stand (frame), transmission system and cutting system are made and designed separately. Study of paper shredder machine included the machine elements which convert manual existing system to automatic system. Paper shredder machine is a mechanical device which is used to cut the paper into chad, typically either strips or fine particles. We are making this project model for recycling of paper wastage(important documents, personal information like social security number, account number, credit card application and other personal information) in domestic area, industrial area etc. in this areas the paper waste is present in large quantity. But the available machines used to recycle this waste are costly. So our intension behind this project is to process the paper waste as cheap as possible by shredding. Benefits of this machine are the reduction of labor work which results in cost reduction and also reduction in time for shredding operation of paper. So we are going to design this for shred the paper waste, with the help of blades.
INTRODUCTION
A paper shredder is a mechanical device used to cut paper into small strips. Government organizations, businesses and private individuals are used to destroy private, confidential, or otherwise sensitive documents into strips or fine particles. Paper shredder machine is utilized to shred the important documents which are misused by some unauthorized person. There are lots of people who spend their day through rummaging garbage to find personal information like social security number, account number, credit card application and other personal information about company to overcome these issues, paper shredders are used. The Paper Shredder is equipped by using all necessary items and method such as aluminium sheet metal, rivet, and skills in manufacturing machine to cut and bend the parts and etc. The process of development is started from designing the shape of the paper shredder by considering the function as well. In order to produce user friendly product that is suitable to the consumer, consideration to the ergonomic factor is taken into account. It involves the measurement process before the materials are cut into pieces before assemble together by using cutting and bending processes. The paper shredder is needed to test to check whether its mechanism is properly work or not work.
这个项目标题是“纸粉碎机的设计和制造”。该项目包括对纸质粉碎机的小分析，并对纸质粉碎机本身的制造具有关于强度，便携性，耐用性，符合人体工程学因素和便利性的担忧。需要进行测试以在制造过程开始之前验证纸屑切割器的强度。需要更多的知识和分析技巧。技能如何解决问题是当该项目推出时，最重要的，并且需要改善。碎纸机的规模和价格从设计的小型和廉价的单位，专为一定数量的页面，商业粉碎服务使用的大型单位成本数十万美元，每小时可以撕碎数百万个文件。虽然最小的粉碎机可能是手工摇滚的，但大多数碎纸机都是电动的。碎纸机随着时间的推移，增加了改善粉碎机用户的体验的功能。现在许多拒绝纸张喂养容量以防止堵塞;其他人具有减少风险的安全功能。 Some shredders designed for use in shared workspaces or department copy rooms have noise reduction.

系统设计
Software used for designing is Creo 3.0.Paper shredder machine from design point of view consists of three main parts: machine
construction, cutting system, transmission system.
机械结构：机器结构由支架，轴承支撑板，螺母和螺栓等组成。
切割刀片
切割系统由轴，切割刀片，垫圈和齿轮组成。切割刀片是圆形刀片，3（三）
切割边缘，带键槽中间的给定圆形孔，安装在主轴和主轴上，如此。In drawing of cutting blades in Creo 3.0 software, cutting blades are equally divided into certain degree of angle and each切割刀片的切削刃通过电弧连接到第二切削刃，直到特定的切削刃。我们设计切割系统以这样的方式，每个刀具叶片的键槽之间的角度为40度。切割刀片以这种方式放置在第一刀片外，从第二刀片分开40度。这种概念用于纸碎纸机。因为那样，权力需要旋转轴大。现在旋转轴的电源比以前的更小。用于切割刀片的材料是EN31钢。
发动机：
Electric motor is electrical device that converts electrical energy into mechanical energy. In certain applications, such as in the
运输业用牵引电机，电动机可以在电动机和发电或制动模式中运行
从机械能产生电能。
