Abstract: Aiming at the problems of low production efficiency，poor consistency of appearance and high labor

intensity in the manual way of packaging tin box sleeve film for bagging drinks and tea，a kind of automatic

equipment for multi-tin box supporting sleeve film was proposed，which integrated application of programmable

logic controller（PLC）control，servo drive，pneumatic drive，industrial robot and other technologies. The equipment integrates square polyvinyl chloride（PVC）film set forming，paper support forming transportation，multi-tin box supporting，tin box group into film，tin box group handling and other processes in one，and can effectively link up the automatic production of each process. Practical production application shows that the equipment has obvious advantages over traditional manual sleeve film method in improving production efficiency，improving sleeve film quality and reducing labor intensity，etc. It is in line with the current trend of transformation and upgrading of manufacturing production structure，and has broad market application prospects.
