Spraying device applied to frameless vehicle door sealing strip structure

The invention discloses a spraying device applied to a frameless vehicle door sealing strip structure. The spraying device is composed of a conveying mechanism, a bottom pipe and a control mechanism. When a rotating ring rotates until a second connecting groove communicates with the interior of a first atomizing nozzle, the first connecting groove communicates with the second connecting groove at the moment, so that paint can be discharged through a second atomizing nozzle, the actual spraying range is effectively widened, and the actual spraying area is effectively enlarged; according to the device, the structural state of the device can be conveniently adjusted according to the actual using condition, then spraying treatment of a sealing mechanism can be efficiently conducted, meanwhile, the using position of a bottom pipe is adjusted through an existing mechanical arm, and the using angle of the bottom pipe is adjusted through an adjusting motor and a driving motor; and therefore, the equipment can efficie
