【摘要】：开袋装置是EPS自动包装机器的重要组成部分，开袋装置包括吸袋部件和抓袋部件。开袋装置的总体结构设计以及动力特性能够直接影响到整个EPS自动包装机器的灌装质量、扎口质量以及最终EPS包装袋成形质量，对EPS自动包装机器整体工作效果起到了关键性作用。因此，对EPS自动包装机开袋装置动力特性研究有很重要的意义。 本文以EPS包装机为例，主要进行下面几个方面的研究： （1）介绍了整台EPS自动包装机各个部分组成，EPS自动包装机的工作流程以及各个部分的设计作用和运动规律。重点分析吸袋部件和抓袋部件的工作原理以及运动规律，通过三维建模软件Pro-E建立了开袋装置吸袋部件的结构实体模型，保证各个零件及组件装配合理。 （2）在开袋装置吸袋部件三维实体模型建立完成后，将Pro-E实体模型转换为运动特性分析软件ADAMS格式，导入到ADAMS软件中。在ADAMS中，对实体模型进行运动连接约束，并对开袋装置吸袋部件平行四边形机构进行运动仿真分析，从而得出开袋装置吸袋部件关键构件的角速度、速度、位移、角加速度与时间的关系曲线，分析时间关系曲线，，得到关键构件运动规律，对后续的关键构件的动力学分析提供理论依据。 （3）对吸袋部件平行四边形机构关键构件进行受力分析，借助ANSYS有限元软件对关键构件进行静力学结构分析，得到关键构件的应力分布和弯曲变形图，总结出吸袋部件产生振动的原因。 通过对EPS自动包装机的开袋装置动力特性研究分析，得出了开袋装置吸袋部件在运动过程当中出现的振动原因，进而针对开袋装置结构进行优化，对EPS自动包装机整体工作性能提升起到了实质性的作用，也让一系列计算机辅助软件在包装机械领域中得到了充分的应用。

The overall structure design and dynamic characteristics of the bag opener can directly affect the filling quality, the opening quality and the final EPS bag forming quality of the whole EPS automatic packaging machine. It plays a key role in the overall working effect of EPS automatic packaging machine. Therefore, it is of great significance to study the dynamic characteristics of the bag opening device of EPS automatic packaging machine. This paper takes the EPS packing machine as an example, mainly carries on the following several aspects research: (1) introduced the whole EPS automatic packaging machine each part composition, the EPS automatic packing machine work flow, each part design function and the movement rule. The working principle and motion law of bag suction parts and bag grasping parts are analyzed emphatically. The structural entity model of bag suction parts of bag opener is established by using 3D modeling software Pro-E.

In ADAMS, the motion connection constraint of the solid model is carried out, and the motion simulation analysis of the parallelogram mechanism of the bag suction part of the bag opener is carried out, and the angular velocity and displacement of the key component of the bag suction component of the bag opener are obtained. The relation curve between angular acceleration and time is analyzed, and the motion law of key component is obtained. It provides a theoretical basis for the subsequent dynamic analysis of the key components.

The stress distribution and bending deformation diagram of key components are obtained, and the causes of vibration of bag suction parts are summarized. Through the study and analysis of the dynamic characteristics of the bag opener of EPS automatic packaging machine, the vibration causes of the bag suction parts of the bag opener are obtained, and the structure of the bag opener is optimized. It plays a substantial role in improving the working performance of EPS automatic packaging machine and makes a series of computer aided software fully applied in the field of packaging machinery.
