The invention relates to a package machine of a cylindrical battery roll core, comprising a stander, a work table, a driving system and an electric control system. The work table is provided with a roil core inputting device, a shell inputting device and a roil core package machine which are driven by the driving system and controlled by the electric control system; and the roil core package machine comprises a shell positioning mechanism, a shell conveying mechanism and a roil core conveying mechanism. The roil core package machine is controlled by the electric control system to be capable for conveying the shell conveyed by the shell input device into the shell positioning mechanism, is fixed by the shell positioning mechanism, and conveys the roil core conveyed by the roil core input device into the fixed shell, so as to realize the work procedure of automatic package, and greatly improve the work efficiency of package. The invention further discloses a roil core shaping device, a circumference positioning device, a cathode ear bending device, a lower insulating sheet conveying device and an upper insulating sheet conveying device, which are corresponding to the work proceduressuch as roil core shaping, circumference positioning, cathode ear bending, lower insulating sheet inputting, upper insulating sheet inputting, etc.
