The invention discloses a watch box semi-automatic packaging machine capable of achieving the self column-alignment putting and conveying function. The machine structurally comprises a machine body, asupporting table, a swing pull arm, an upper packaging table, a work panel, press fit mechanisms, a storage box, and a control panel; a mounting frame is fixed above the interior of the supporting table, fixed rods slide along a base plate for distance adjusting and are in gap attaching with watch boxes, it can be ensured that the watch boxes can be arranged at equal intervals side by side, mis-operation caused by midway adjusting by a person is avoided, a transmission gear penetrates through a shaft part in the machine and bears loads through friction of a shaft sleeve, meanwhile, side wallwheel teeth are used for pushing a pull rod and a connecting column to do linear rotation back and forth, transverse power is generated, in cooperation with the fixed rods, the intervals are pulled open, the watch boxes are directly conveyed for packaging, collision and mis-position mounting can be avoided, watches inside the boxes can be protected again, the whole work proceed can be quickened, and the service life is prolonged.
