Besides, designed tester and tested sealing quality. Inthe entire machine design, established working cycle and conformed work in relations ofmain fixtures(feeding ,forming, retractor, sealing, driving)through analysis ofpackaging machine overall plan; completed the modified structure design ofthe forming filling sealing packaging machine and conformed the main parameters. Inthis paper, designed the horizontal sealing fixtures and advanced new forming fixture which can adjust the packaging length and extended the useable range ofthe packaging machine and studied. Atthe same time, offered amethod ofparallel measure feeding and founded vibration feeding fixtures ofoscillatory differential equation. This study can direct the design and exploitation ofother bag packaging machine actively. Using the tester carries onthe package sealing test, the tensile test and the endure stress test that the tests were based onthe national standards, experimented data and the results indicate sealing intensity conforms tothe national standard. Through data analysis obtained the permits packing sealing temperature range and the relations ofthe sealing intensity ofthe horizontal fixtures and the vertical sealing fixtures ,time and temperature and the best packing material sealing condition.
