Automatic paint spraying device for inner surface of barrel bottom cover

Abstract

The utility model discloses an automatic paint spraying device for the inner surface of a barrel bottom cover, and belongs to the field of paint spraying devices. The automatic paint spraying device for the inner surface of the barrel bottom cover comprises a fixed base, a connecting flange is arranged on the fixed base, a first hydraulic cylinder is arranged on the connecting flange, a fixed block is arranged at the movable end of the first hydraulic cylinder, the automatic paint spraying device further comprises a pressure pump, and the pressure pump is arranged at the upper end of the fixed block. And a paint connecting pipe is arranged at the upper end of the pressure pump. The paint spraying device solves the problems that an existing paint spraying device can only conduct spraying work on the outer surfaces of objects with regular shapes, and when the inner walls of barrel type objects need to be sprayed, due to the fact that the depth of the interior of a barrel is large, and the caliber of a feeding pipe allowing a spraying head to enter is small, the spraying efficiency is high. And therefore, a traditional paint spraying device cannot carry out good spraying work on the interior of the barrel.
