| This study included the modified structure design of the forming filling sealing packaging machine, the finite element analysis and solid modeler.Besides, designed tester and tested sealing quality.In the entire machine design, established working cycle and conformed work in relations of main fixtures(feeding, forming, retractor, sealing,driving) through analysis of packaging machine overall plan; completed the modified structure design of the forming filling sealing packaging machine and conformed the main parameters.In this paper, designed the horizontal sealing fixtures and advanced new forming fixture which can adjust the packaging length and extended the useable range of the packaging machine and studied.At the same time,offered a method of parallel measure feeding and founded vibration feeding fixtures of oscillatory differential equation.This study can direct the design and exploitation of other bag packaging machine actively.In the solid modeler design, adopted virtual prototype technology instead of traditional design.Based on making design calculations, studied solid model, virtual assembly on the platform of CAXA and numeric prototype, the movement simulation of solid mechanism was realized. The simulation result indicated the reformative design and provides basis to processing physical prototype. Carried on the finite element analysis to the essential structure based on CAXA V5 3D, the intensity accorded design request.Using the tester carries on the package sealing test, the tensile test and the endure stress test that the tests were based on the national standards, experimented data and the results indicate sealing intensity conforms to the national standard. Through data analysis obtained the permits packing sealing temperature range and the relations of the sealing intensity of the horizontal fixtures and the verticalsealing fixtures, time and temperature and the best packing material sealing condition.
