【摘要】：開袋裝置是EPS自動包裝機器的重要組成部分，開袋裝置包括吸袋部件和抓袋部件。開袋裝置的總體結(jié)構(gòu)設(shè)計以及動力特性能夠直接影響到整個EPS自動包裝機器的灌裝質(zhì)量、扎口質(zhì)量以及最終EPS包裝袋成形質(zhì)量，對EPS自動包裝機器整體工作效果起到了關(guān)鍵性作用。因此，對EPS自動包裝機開袋裝置動力特性研究有很重要的意義。 本文以EPS包裝機為例，主要進(jìn)行下面幾個方面的研究： （1）介紹了整臺EPS自動包裝機各個部分組成，EPS自動包裝機的工作流程以及各個部分的設(shè)計作用和運動規(guī)律。重點分析吸袋部件和抓袋部件的工作原理以及運動規(guī)律，通過三維建模軟件Pro-E建立了開袋裝置吸袋部件的結(jié)構(gòu)實體模型，保證各個零件及組件裝配合理。 （2）在開袋裝置吸袋部件三維實體模型建立完成后，將Pro-E實體模型轉(zhuǎn)換為運動特性分析軟件ADAMS格式，導(dǎo)入到ADAMS軟件中。在ADAMS中，對實體模型進(jìn)行運動連接約束，并對開袋裝置吸袋部件平行四邊形機構(gòu)進(jìn)行運動仿真分析，從而得出開袋裝置吸袋部件關(guān)鍵構(gòu)件的角速度、速度、位移、角加速度與時間的關(guān)系曲線，分析時間關(guān)系曲線，，得到關(guān)鍵構(gòu)件運動規(guī)律，對后續(xù)的關(guān)鍵構(gòu)件的動力學(xué)分析提供理論依據(jù)。 （3）對吸袋部件平行四邊形機構(gòu)關(guān)鍵構(gòu)件進(jìn)行受力分析，借助ANSYS有限元軟件對關(guān)鍵構(gòu)件進(jìn)行靜力學(xué)結(jié)構(gòu)分析，得到關(guān)鍵構(gòu)件的應(yīng)力分布和彎曲變形圖，總結(jié)出吸袋部件產(chǎn)生振動的原因。 通過對EPS自動包裝機的開袋裝置動力特性研究分析，得出了開袋裝置吸袋部件在運動過程當(dāng)中出現(xiàn)的振動原因，進(jìn)而針對開袋裝置結(jié)構(gòu)進(jìn)行優(yōu)化，對EPS自動包裝機整體工作性能提升起到了實質(zhì)性的作用，也讓一系列計算機輔助軟件在包裝機械領(lǐng)域中得到了充分的應(yīng)用。
[Abstract]:Bag opener is an important part of EPS automatic packaging machine. 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. (2) after the establishment of the three-dimensional solid model of the bag suction part of the bag opener, the Pro-E solid model is transformed into the ADAMS format of the motion characteristic analysis software and imported into the ADAMS software. 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. (3) the stress analysis of the key components of the parallelogram mechanism of bag suction components is carried out, and the statics structure of the key components is analyzed with the help of ANSYS finite element software. 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.
