Bottle cover preprocessing mechanism

The utility model provides a bottle cover preprocessing mechanism. The bottle cover preprocessing mechanism comprises a horizontal conveying belt and an inclined conveying belt, wherein a part of the inclined conveying belt is located below the horizontal conveying belt, and a plurality of partition plates perpendicular to the inclined conveying belt are evenly distributed on the inclined conveying belt. A bottle cover preprocessing unit comprises an installation plate, a liquid medicine spraying nozzle, a water spraying nozzle, a liquid medicine pump and a water pump. The installation plate is located above the inclined conveying belt and parallel to the inclined conveying belt. The liquid medicine pump and the water pump are arranged on the upper surface of the installation plate. The liquid medicine spraying nozzle and the water spraying nozzle which are perpendicular to the installation plate are installed on the lower surface of the installation plate. The liquid medicine pump is connected with the liquid medicine spraying nozzle. The water pump is connected with the water spraying nozzle. The liquid medicine spraying nozzle is close to the horizontal conveying belt. The water spraying nozzle is away from the horizontal conveying belt. A plurality of through holes are evenly formed in the partition plates. The bottle cover preprocessing mechanism is low in cost, ingenious in structure, small in occupied area, and capable of being seamlessly connected with a subsequent device so that work can continue.
