The invention belongs to the technical field of carton sheet pushing, and in particular relates to a carton sheet up-dial pushing device used in the packaging field, which includes a geared motor, an adjustment mechanism, a paper storage case, a paper feeding roller, a guiding telescopic plate, a transmission mechanism, a bottom plate, and a stopper. Cardboard, paper licking roller, the push outlet of the push device designed in the present invention is located on the upper side of the paper storage case, so that after each push of a carton piece, the pushed out carton piece will not be affected by other carton pieces, and the push resistance is small The carton sheet pushing device designed by the present invention adds a paper feed roller in the process of pushing the carton sheet, so that the length of the carton sheet only needs to be greater than the distance between the bottommost side of the paper feed roller and the pressure roller, In this way, the highest point that the paper licking roller can move can be relatively increased, and when the carton pieces are first placed in the paper storage case, the number of carton pieces in the paper storage case can be increased, so that the use efficiency of the device becomes high.
