Abstract

A spraying system includes a spraying device, a toasting device, a conveyor line, and a turning device. The spraying device is configured to spray a workpiece. The toasting device is configured to toast the workpiece. The conveyor line passes through the spraying device and the toasting device and is configured to convey the workpiece. The turning device is coupled to the conveyor line and includes a first fixing frame across the conveyor line, a turning mechanism, and a blocking member. The turning mechanism includes a bearing frame detachably coupled to the conveyor line, a rotation shaft rotatably coupled to the bearing frame; a rotatable member coupled to the rotation shaft; and a positioning member coupled to the rotation shaft and configured to couple the workpiece. The blocking member is coupled to the fixing frame and configured to block the rotatable member to rotate the rotation shaft, the positioning member.
