Positioning device for interval gluing rolls of assembler

The utility model discloses a positioning device for an interval gluing roll of an assembler, which belongs to the field of cigarette making mechanical equipment and comprises a gear of an upper gluing roll shaft and a gear of a lower gluing roll. Four pins are evenly disposed on one side of the upper gluing roll, and a positioning flange is fixed to one side of the gear of the lower gluing roll through screws. Five grooves corresponding to gear pins of the upper gluing roll shaft are arranged on the outer periphery of the positioning flange. After the positioning device is assembled, the lower gluing roll is convenient and quick in positioning and mounting, quality accidents are not easy to occur, and the lower gluing roll is highly operable. Therefore, intended purposes of modification are achieved.
