This invention discloses a capping mechanism for small-pitch double-bottle bottles. The mechanism includes a frame, a fixing clamp, and two toothed capping heads. A movable groove is provided at the bottom of the frame, and the fixing clamp is flexibly and vertically positioned inside the groove. A vertically movable fixed plate is provided at the top of the frame, with two rotatable rotating rods on the plate. The two toothed capping heads are fixed to the bottom of the rotating rods, and drive gears are provided at the top of the rotating rods. A drive component is provided on the fixed plate to synchronously drive the two drive gears, and a controller is provided on the drive component. A downwardly extending calibration rod is provided on the fixed plate. When the toothed capping heads tighten the cap onto the double-bottle bottle, the bottom of the calibration rod abuts against the double-bottle bottle. A pressure sensor is provided at the bottom of the calibration rod, and the pressure sensor is electrically connected to the controller. This invention improves the tightening efficiency between the cap and the opening of the double-bottle bottle.
