The utility model discloses a
bottle outer wall cleaning device which comprises a conveying mechanism, positioning assemblies are distributed in the conveying direction of the conveying mechanism and used for enabling
wine bottles to be vertically kept on the conveying mechanism, and cleaning stations are distributed in the conveying direction of the conveying mechanism and used for enabling the
wine bottles to be vertically kept on the conveying mechanism. The
cleaning station is provided with a cleaning
brush, a support fixedly arranged above the conveying mechanism and a
bottle grabbing mechanism installed on the support, the cleaning
brush is installed on one side of the conveying mechanism, and the
bottle grabbing mechanism comprises a clamping
assembly, a rotating
assembly controlling the clamping
assembly to rotate and a lifting assembly controlling the clamping assembly to ascend and descend. After the conveying mechanism conveys a
wine bottle to the position of the cleaning
brush, under the synergistic effect of the lifting assembly, the clamping assembly can fixedly clamp the
wine bottle and keep the
wine bottle in a suspended state, the rotating assembly drives the clamping assembly to rotate, and the side wall of the
wine bottle can be made to be in rolling friction relative to the cleaning brush. The wine bottle cleaning device has the advantages that the cleaning effect of the outer wall of a wine bottle is improved, and the cleaning efficiency is guaranteed.
