Automatic spraying production line

The invention relates to an automatic spraying production line. The automatic spraying production line comprises a speed chain line body, a workpiece lifting hook is connected to the speed chain linebody, an automatic feeding device, a first spraying chamber, a first drying chamber, a second spraying chamber, a second drying chamber and an automatic discharging device are sequentially arranged inthe running direction of the speed chain line body, and automatic spraying mechanisms are arranged in the first spraying chamber and the second spraying chamber. According to the automatic spraying production line, when a motor shell is sprayed, the speed chain line body drives the lifting hook to move, and when the lifting hook moves, the lifting hook can sequentially pass through the automaticfeeding device, the first spraying chamber, the first drying chamber, the second spraying chamber, the second drying chamber and the automatic discharging device, so that a motor is driven to sequentially perform automatic feed
