The invention relates to a toothed paper slip stacking device which comprises a machining table, wherein a paper slip gumming machine is mounted on the left side of the machining table; a paper slip erection frame is mounted in the middle of the machining table; a paper slip stacking machine is mounted on the right side of the machining table; the paper slip gumming machine comprises a gumming wheel; supporting plates fixed on the machining table are movably arranged at the front and rear ends of the gumming wheel in a sleeved manner; gum hiding heads are uniformly distributed on the gumming wheel; grooves are formed in the upper ends of the gum hiding heads; a glue box fixed on the machining table is arranged below the gumming wheel; and a glue liquid is filled in the glue box. The strip-shaped toothed paper is gummed by adopting the conical gum hiding heads, and the control precision of the glue liquid suction amount can be effectively improved by controlling the sizes of the grooves in the gum hiding heads. Compared with the existing hairbrush gluing, the toothed paper slip stacking device has the advantages that the control effect is excellent, and the gumming efficiency is high.
