Study On The Dynamic Characteristics For Bag Opening Mechanism In EPS Packaging Machine

Bag opening device is an important part of EPS automatic packing machine, bagopening device includes suction bag part and grab bag part. Bag opening device generalstructure design and the dynamic characteristics of EPS automatic packaging machinecan directly affect the whole filling quality, working quality and final EPS packagingforming quality, and has played a key role in the general work of EPS automaticpackaging machine. Therefore, the dynamic characteristics of EPS automatic packagingmachine bag opening device research have very important significance.Based on EPS packaging machine as an example, this paper mainly conductsresearch in the following way:(1) This paper introduces the whole EPS automatic packaging machine parts, EPSautomatic packaging machine of the design of each part and the working process andfunction and movement rules, focus on analysis of suction bag components and workingprinciple of grab bag of parts and motion. Through3d modeling software Pro-Eestablish the structure of the bag opening device suction bag parts entity mode. Ensureall parts and components assembly is reasonable.(2) After the completion of the three-dimensional entity model of the bag openingsuction bag parts, convert Pro-E solid model to the movement characteristics analysissoftware ADAMS format, Imported into the ADAMS software. In ADAMS, entitymodel for kinematic joint constraints, and Folio bag device suction bag partsparallelogram mechanism motion simulation analysis. then obtain the bag devicesuction bag key component parts of angular velocity, velocity, displacement, angularacceleration and the relation curve of the time, The key component analysis time curve,movement rule. The key component of subsequent provide theoretical basis for thedynamic analysis.(3) Make the stress analysis for Key components of suction bag parts parallelogrammechanism, with the help of ANSYS finite element software, the key component forstatic structural analysis. By bending stress distribution and deformation of keycomponents, sums up the causes of vibration suction bag of parts.Through open a bag of EPS automatic packaging machine device dynamiccharacteristics research and analysis, it is concluded that the suction bag bag openingdevice components in the movement process of vibration. Then open the bag devicestructure is optimized, EPS automatic packing machine for the overall workperformance plays a substantial role, also let a series of computer aided software in thefield of packaging machinery has been fully used.
