The utility model discloses a cut coiling mechanism of formula stock form, including the frame, form advance roller, preceding backing roll, back backing roll and the tube core of parallel arrangementin the frame, still, locate the slotting tool cylinder of preceding backing roll top and install the slotting tool in slotting tool cylinder below just towards an exhaust gas mouth of tube core including lieing in back backing roll top, the top of tube core after the roller of form advancing, in the past upwards around above the backing roll of back between backing roll and the back backing roll,under the effect of an exhaust gas mouth, is walked around to paper after cutting, and under the guide effect of slotting tool to the underthrust, the paper is pushed up to the top of preceding backing roll, under the drive of paper, is drawn into the lower end of tube core, rolling in the periphery of tube core. The utility model discloses because of the top of backing roll after upwards windingextremely between paper the past backing roll and the back backing roll, the paper after being blown can not produce ascending power to the tube core, and such structure very is fit for in automaticcontrol's the equipment.
