Abstract:
A composite barrel curled edge paint-repair-free method. A composite barrel comprises a barrel lid (10), a barrel body (20), a barrel bottom (30) and an inner container (50), wherein the barrel lid is provided with a movable lid body. The composite barrel curled edge paint-repair-free method comprises: assembling the barrel body and the barrel bottom, and assembling the barrel body and the barrel lid, so as to form a barrel body (100); spraying paint onto outer surfaces of the barrel body, the barrel bottom and the barrel lid by means of a spraying apparatus, and baking the paint; conveying the barrel body to a vertical capping machine; opening the movable lid body, and assembling and then mounting the inner container and the movable lid body onto an inner cavity of the barrel body; and remounting the movable lid body on the barrel lid by means of the vertical capping machine. By means of the method, the efficiency of mounting the inner container can be improved, and paint repair is also avoided.
