[0004] However, with regard to the current conventional turning device, during the process of turning over the paper box, due to the material of the paper box, the paper box is easily deformed during the turning process, resulting in the paper box being offset after turning over, causing the printing of the turned paper box to be misaligned, affecting the printing quality of the paper box, and being inconvenient to use. Utility Model Content

[0005] In view of this, the utility model provides a turning device for color printing of a paper box, which has an aligning push block which can automatically position the turned paper box after the paper box is turned over. After the turning frame clamps the paper box, the driving motor is started to drive the driving motor to rotate the first gear. During the rotation of the first gear, the second gear meshed with the first gear is driven, and the turning frame is turned over by the rotation of the second gear. The paper box is turned over by the turning frame and turned over onto the rear conveyor belt. Subsequently, the electric push rod is started again to reset the turning clamp, so that the turned paper box is transported to the printing place through the rear conveyor belt to perform color printing on the turned paper box.
