Objective To reduce the speed deceleration and change during reel change of aluminum foil compound device, and solve the problem of broken pieces of aluminum foil during reel change, so as to improve the overall equipment efficiency (OEE). Methods Based on the analysis of the experimental data by the methods of 5W1H and tension analysis, a dynamic model was established on the foil tension during reel change of the aluminum foil compound device. The research explored many factors that affected the foil tension such as roller tension and pressure, foil eccentricity, direction angel of centrifugal movement, speed difference and so on. The practical operation was experimentally improved. Results The speed variation during the reel change of the aluminum foil was improved and the problem of broken pieces was solved. Conclusion Through the adjustment of many factors that affected the foil tension, the OEE reached 92.1% and the production efficiency was improved.
