Design Of Packing System Hopper Structure Based On The Finite Element Analysis

In the field of industrial production and food processing, a large amount of solid material need to be transported after packed, such as packaging soybean, bran, starch and others in the food processing enterprises. In the present domestic market, this kind of packaging material has achieved mechanization and part of automation, but there is a considerable part of the work must be done by manpower. In the industrial developed countries, similar equipment has already been equipped by automation system. However, beside high cost, this kind of equipment often have higher requirements on production environment, packaging materials and equipment, and can't adapt to the current situation of most domestic enterprises.The purpose of this paper is to design a set of automatic material bagging system which can adapt to the domestic market, and give thorough introduction to hopper module design process. The whole process follows a complete system development process, and adopts an advanced dynamic design method.The design scheme of the whole system and the manufacture of the finished product of material bagging system are based on the analysis of the initial requirements of the hopper module. After manufacturing integration and debugging the prototype, the prototype was found working slowly. In order to improve the overall rhythm, changing the plan of system and hopper module based on analysis of the shortage of bagging prototype system and the hopper. According to the new scheme of the system and the hopper, analyzing the other internal design requirements of the hopper module,and designing and building a 3D model of the hopper.By performing stress analysis on the hopper, the stress of component and displacement of parts have been worked out. The finite element analysis of the hopper has been conducted. According to the frequency and the corresponding vibration mode by modal analysis, the dynamic characteristics of hopper can be estimated.Finally, using Solidworks Simulation optimization function optimized the hopper activities section parts. In the case of stress allows, reducing its quality, achieving the goal of lightweight. The optimized hopper was lighter 45.3% than not optimized. Modal analysis was carried out on the hopper after the optimization module, characteristic frequency wasn't much different from before. The stiffness and mass distribution is balanced, there were not obvious weak parts and eXcess parts. The dynamic characteristics were in line with eXpectations.
