摘要脚踏式封箱机是机械式钉箱机的一种，是使用者通过脚踏钉箱机踏板，经过一系列机械结构完成钉箱的程序，最后再通过松踏板来实现复位的一种机械结构。本论文的主要内容是设计脚踏式封箱机的机械结构来满足上述的使用要求。此结构设计中，最主要的内容是钉箱功能机构的设计以及解决复位要求问题。84081

首先，笔者搜集了封箱机的相关资料，了解了国内外封箱机的发展情况以及未来的发展趋势，分析了各类封箱机的使用场合以及市场需求。最终决定设计在国内市场需求仍然较高的单一机械式脚踏封箱机。通过分析脚踏式封箱机的工作原理以及过程，再通过借鉴普通订书机的机械结构，完成脚踏式封箱机的钉箱功能机构的设计方案的确定。

然后，用Solidworks三维制图软件对脚踏式封箱机的机械机构进行三维建模，以便形象地表示出脚踏式封箱机的工作原理以及机械结构。对重要零件进行受力分析并用Solidworks 中的Simulation插件对零件进行静力学有限元分析，来检验结构设计是否满足强度要求。根据静力学分析的结果对设计缺陷或强度不满足设计要求的零件进行修改。用Solidworks Motion进行运动学分析，方便表示出脚踏式封箱机的工作过程。

最后，绘制脚踏式封箱机的Auto Cad二维机械图纸。

AbstractThe Pedal sealing machine is one of mechanical box nailing machines。 The user can nail boxes by footing the pedal of the machine which will complete the procedure of nailing boxes through a series of mechanical structure。 Finally, the machine will reset when users release the pedal。 The main content of this paper is to design the mechanical structure of pedal sealing machine to meet the above requirements。 In this design, the main content is the design of the structure of nailing function and solving the request of resetting。

First of all, the author collected the relevant information of the sealing machines and understanding the development of the domestic and international sealing machines and the trend of development in the future。 The author also analyzed the market demand of various types of sealing machines and knows where to use。 At last, the author decided to design single mechanical foot sealing machine whose demand is still high in the domestic market。 Through the analysis of the pedal box sealing machine’s working principle and process, the author determined the design of the structure of nailing function of the pedal box sealing machine by imitating the mechanical structure of the ordinary stapler。

Then, the three-dimensional model of the mechanism of the pedal sealing machine is made by using Solidworks software in order to express the mechanical structure and working principle of the pedal sealing machine。 Also Solidworks Simulation is used to analyze the structure and the finite element analysis in order to verify whether the structural strength meets the requirements。 According to the results of the analysis, we need to improve the design of the structure which is unreasonable or unable to meet the requirements of strength。 To carry out the kinematic analysis Solidworks Motion is used so that the working process of the pedal type sealing machine is apparent。

Finally, the mechanical structure of the mechanical structure of the machine is transformed into Cad Auto 2D drawings。
