| Abstract: |
| Targeting at problems such as lower packaging efficiency, higher labor-consuming and others in mustard packaging industry currently, the design of existing mustard filling machine was improved in this study. Based on TRIZ theory, problems in the design process was summarized and analyzed, the corresponding innovative design principle was obtained and the best principle was chosen to solve the problem of the technical conflict in the design through the establishment of designing conflict matrix on bag supplying mechanism, bagging mechanism and vacuum heat sealing mechanism. The technology conflicts in bag supplying mechanism suitable for packaging bags of different sizes 93 mm × 138 mm and 125 mm × 175.5 mm and the conflicts between the fast bag frequency and the structure complexity of bagging were solved. The technology conflicts in keeping bags open and the structure complexity of bagging when the production rhythm reached 40 bags/minute were solved. What′ s more, problems on improving the vacuum thermal sealing efficiency, structural convergence of each structure and the emergence of logistics transportation caused by the changes of thermal sealing structure were solved. Through the integrated use of TRIZ theory, the technical conflict problem related to design of new mustard packaging machine was solved based on mustard filling machine platform. The automated production was realized. |
