A multi-column strip
packaging machine comprises a film feeding mechanism, a
color code detection mechanism, a longitudinal sealing mechanism 4, a first transverse sealing mechanism, a second transverse sealing mechanism and a
punching mechanism, the longitudinal sealing mechanism 4 comprises a strip packaging guide forming module, a first follow-up lifting module and longitudinal sealing modules, and the first follow-up lifting module drives a plurality of sets of longitudinal sealing modules to synchronously ascend and descend along with strip packaging; the first transverse sealing mechanism and the second transverse sealing mechanism are parallel to each other up and down, are respectively used for carrying out first transverse sealing and second transverse sealing on the
carton package, and respectively comprise a lifting driving module, a second mounting frame, a front heat sealing module, a rear heat sealing module and a transverse sealing driving module; the
punching mechanism comprises a second follow-up lifting module, a third mounting frame, a front cutter module, a rear cutter module and a cutter driving module. The second follow-up lifting module drives the front cutter module and the rear cutter module to ascend and descend in a follow-up mode. According to the full-automatic
carton packaging machine, two-pass transverse sealing can be carried out on a
carton, alternate film drawing, follow-up longitudinal sealing and
punching can be carried out, the production speed can be increased, the carton quality can be improved, and the overall structure is compact.
