Abstract

An automatic lacquer shaking-off machine for screws includes a material feeding unit, a pail conveyer, an immersing coating unit, and a dry conveyer. The material feeding unit feeds a batch of screws to be coated of the same volume every time into a pail. Then the pail is transported by the pail conveyer to the immersing coating machine, wherein pours lacquer or oil in the pail to immerse and coat the screws in the pail, and then pail with screws and lacquer therein rotated in a centrifugal way for shaking excessive lacquer on the screws off. Then the pail containing treated screws is taken out of the immersing and coating machine, and then the screws in the pail are poured on the drying conveyer for drying screws, finishing the whole process of coating and shaking off lacquer off screws.
