When the rotation angle of the rotating disk 4 is between 0 degrees and 180 degrees, the pull rope 7 arranged on the surface of the rotating disk 4 gradually moves from the bottom of the rotating disk 4 to the top of the rotating disk 4. The movement of the pull rope 7 pulls the sealing rod 12 upward through the pull plate 10, so that the bottom end of the sealing rod 12 withdraws from the glue dripping port 14, and the glue in the rubber hose 13 is able to drip from the glue dripping port 14 to the part of the paper bag to be glued to the bottom; when the rotating disk 4 rotates to 18 When the angle is between 0 and 360 degrees, the pull rope 7 gradually moves from the top of the rotating disk 4 to the bottom of the rotating disk 4, and the sealing rod 12 moves downward after losing the pulling force, and is reinserted into the glue dripping port 14 to seal the glue dripping port 14, thereby stopping the glue from dripping. In this way, according to the amount of glue required for pasting the bottom of a single paper handbag and the speed at which the glue drips from the glue dripping port 14, the time for the glue in the glue hose 13 to drip the amount of glue required for pasting the bottom of a paper handbag can be obtained.
