The utility model relates to the technical field of automatic spraying for fasteners, and discloses an automatic spraying device for fasteners, which comprises a main body mechanism and a spraying mechanism, the spraying mechanism is fixedly mounted in the main body mechanism, the main body mechanism comprises a spraying
machine, a base and a shell, the base is fixedly mounted at the bottom end of the spraying
machine, and the shell is fixedly mounted at the bottom end of the spraying
machine. And a shell is fixedly mounted on the outer surface of the spraying machine. According to the stable and efficient conveying
system with the efficient spraying performance, the conveying belt
system can stably convey fasteners, the speed of the conveying
system can be adjusted (0.5-5 m / min), and the conveying speed can be flexibly adjusted according to actual production requirements and spraying
process requirements. For example, when high-quality and high-precision spraying operation is carried out, the speed of the conveying belt can be properly reduced, so that each
fastener has enough time to be uniformly sprayed under a spraying gun, and the spraying quality is improved.
