The invention discloses an automatic collecting device for stamping machine waste base films and relates to the technical field of package printing. The automatic collecting device is installed at theoutput end of an abandoned base film layer and comprises a worktable. A drive roller and a driven roller which are arranged in parallel are arranged at the high end of the worktable. Multiple protrusions are arranged on the outer circumference face of the drive roller in a circumference array manner, and multiple grooves used in cooperation with the protrusions are formed in the outer circumference face of the driven roller. A first rotating rod, a collecting cylinder and a second rotating rod are sequentially arranged at the low end of the worktable in sequence from front to rear, one end ofthe first rotating rod is rotationally connected with the worktable, the other end of the first rotating rod is rotationally connected with one end of the second rotating rod through the collecting cylinder, the other end of the second rotating rod is rotationally connected with the worktable, and the axis of the collecting cylinder is parallel to that of the drive roller or the driven roller. Bymeans of the automatic collecting device for the stamping machine waste base films, the base films discharged by the stamping machine can be automatically collected, and the phenomenon that the basefilms are thin and are not easy to enter the automatic collecting device is prevented.
