An automatic spraying device for the production of liquor bottle caps

Abstract

This utility model discloses an automatic spraying device for producing liquor bottle caps, including a bracket. A spray gun and an air gun are mounted on the side wall of the bracket. Multiple sets of transmission wheels are rotatably connected inside the bracket, and these sets are interconnected via a transmission belt. Multiple sets of rotating shafts are equidistantly arranged on the outer wall of the transmission belt. A sleeve is fixedly connected to the upper end of each set of rotating shafts. An adjustment groove is formed through the outer wall of the sleeve. Two sets of rotating plates are symmetrically arranged within the adjustment groove, and both sets of rotating plates are rotatably connected to the groove. Rollers are rotatably connected to the ends of each rotating plate. An adjustment mechanism for driving the rotating plates is installed within the adjustment groove. This utility model uses gears and racks to drive a threaded rod, which in turn drives a slider and a connecting plate to ensure that the rollers at the ends of the rotating plates fit against the inner wall of the bottle cap. This ensures stable rotation of the bottle cap under the drive of the air gun, avoiding localized overspray or underspray due to shaking, and improving the uniformity of the coating thickness.
