According　to　the　characteristics　of　the　end　sealing　mechanism　of　the　packaging　machine　in　the　market,　a　new　highspeed　fixed　end　sealing　device　is　designed　based　on　TRIZ　(Theory　for　Solving　Inventive　Problems)　in　this　paper.　The　three-dimensional　model　of　the　mechanism　was　carried　on　by　SolidWorks　and　the　dynamics　simulation　was　carried　on　by　ADAMS.　The　movement　rule　of　the　key　components　of　the　end　sealing　mechanism　was　obtained　through　the　dynamic　analysis.　Then　the　prototype　construction　and　the　actual　packaging　sealing　experiment　was　carried　on.　The　experiment　results　show　that　the　packaging　effect　is　good　and　the　packaging　rate　and　packaging　speed　can　meet　the　actual　production　requirements.　It　has　profound　significance　to　promote　the　development　of　packaging　machinery　and　promote　packaging　automation.　©2019　IEEE.
