The invention discloses an incense spraying bone water passing mechanism, and relates to the field of incense spraying production, the incense spraying bone water passing mechanism comprises a transfer device, the transfer device comprises a top frame, a left side frame, a right side frame and a bottom frame, the top frame is slidably connected with a first sliding rail, and the left side frame and the right side frame are arranged at the left end and the right end of the top frame and extend towards the bottom of a rack; a left sliding plate and a right sliding plate which move in the vertical direction are arranged on the left side frame and the right side frame correspondingly, and the two ends of the bottom frame are rotationally connected with the left sliding plate and the right sliding plate correspondingly. The clamping mechanism on the bottom frame is used for clamping the incense sticks on the conveying belt, the third driving device converts the incense sticks from the horizontal posture to the vertical posture, and the second driving device stretches the incense sticks in the vertical posture into the water tank to be soaked. The soaked incense sticks are driven by the first driving device, the second driving device and the third driving device to be placed on the conveying belt again in the horizontal posture, the transfer device continues to soak the incense sticks on the conveying belt, continuous work of the water passing mechanism is achieved, and the incense spraying production efficiency is improved.
