摘  要

封口机是一种包装机械，目前在我国非常落后，特别是火工产品包装设备，基本为手工和半自动包装。本设计为设计一台全自动塑料盒封口机，用于蓄电池的包装。通过对封口机的使用条件、功能及设计参数的分析，将机器的总功能分为功能元，提出各功能元的最优方案；根据最优方案进行结构设计、具体零部件的材料选择、强度计算，最终确定零部件结构尺寸；再根据总体方案进行系统的总驱动、总控制设计。经过一番对气动系统和控制系统的研究，了解其工作原理及控制方法，就可以认识到封口机的工作过程。
蓄电池外壳热封口机的基本结构设计是由一个机架组架、上料传动机构、上下料机构、精密模架双头封口机构、气缸-连杆増力机构和气动系统、液压缸-连杆増力机构和液压系统、电器控制系统及软件。其所实现的快速封口主要由上下料机构决定，其主要由三个气缸-连杆机构统和三个具有双圆弧的推动薄片所形成的动力系统，盛放上下料机构的侧立板以及其上的定位装置和精密模架双头封口机构。
此封口机通过气缸来实现盒子的运动，加热，冷却及夹紧。通过此封口机，可以实现人力的解放，并更好的保证了产品的安全，提高包装质量，提升生产效率，进而获得更大的利润。

Abstract

 
    Sealing machine is one kind of packaging machinery, we are currently lagging far behind other country, especially the explosive product packaging device, basically depend on the manual and semi-automatic packaging. The design of the plastic box of automatic sealing machine is use for Storage battery fully. Sealing machine through the use of the conditions, functions and design parameters of the analysis, the overall function of the machine is divided into functional element, the element of the function of the optimal program; in accordance with the structural design of the optimal program, the specific components of the material selection, strength calculated to determine the ultimate size parts; overall plan is based on the total driving system, the total control design. After a series of pneumatic system, control system research and then you can understand its working principle and control methods, and it will show you the work of the process of sealing machine.
    The basic structure of the battery casing heat sealing machine is designed by a rack set of frame transmission mechanism, feeding, loading and unloading mechanism, precision mold base double sealing mechanism, cylinders - rod increase the force of institutions and pneumatic systems, hydraulic cylinders - rod increasing force agencies and hydraulic systems, electrical control systems and software. The rapid sealing of its achievement is mainly determined by the upper and lower feed mechanism consists of three main cylinder - linkage mechanism system , three double sheet in promoting the formation of the power system, in full bloom the lateral plate of the upper and lower feeding mechanism and on the positioning device and precision mold base stud sealing mechanism.
    The Sealing machine transits the cylinder to achieve the movement, heating, cooling and clamping of the box. Through the sealing machine, you can achieve the liberation of human and it can better guarantee the safety of the product and improve the quality of packaging and elevate product efficiency, then earning more profit.
