Automatic production line for paint spraying of security doors

The invention relates to an automatic production line for paint spraying of security doors, and mainly solves the problems that when paint is sprayed for existing security doors, the paint spraying quality is poor, a workshop environment is polluted, health of operators is harmed, the production efficiency is low, oil mist explosion is easily caused, and accumulated paint needs to be cleaned frequently. The automatic production line for paint spraying of security doors is characterized in that a spraying station (10), a drying station (11), a security door unloading station (12), a security door loading station (13) and a sprinkling station (14) are successively arranged on a walking track of a chain (101) on a chain type conveying device (1), and an outer spray gun device (18) and an inner spray gun device (19) are separately mounted on the spraying station (10) and correspond to a side wall of a box (3) and a middle partition (9). Production rhythm is controlled by a PLC, the paint is sprayed for the securi
