The advantages are: by setting a connecting plate and a moving plate, a connecting shaft is set inside the connecting plate and the moving plate. When in use, the bottle is placed on the top of the support plate, and the two ends of the bottle are respectively located on one side of the two positioning plates and fixed, and printing is performed through the printing equipment on the cylinder. During the printing process, the second motor is started to rotate the connecting shaft, and the two positioning plates and the entire bottle body are rotated through the two connecting shafts, so that printing can be performed at different positions on the bottle body, and there is no need to install and disassemble the bottle multiple times, which is easy to operate and improves the printing quality.

[0004] At present, the traditional printing mechanism usually uses a single motor to drive the material inside the device to rotate during use.
