[0042] Specifically, in the embodiment, the number of the carrier devices 11 is two groups, and the two groups of carrier devices 11 are arranged on the first guide rail 10. The two groups of carrier devices 11 clamp the external workpiece 100 and then move to the position directly below the printing head 2, so as to realize the continuous work of the printing head 2 and improve the efficiency. In order to distinguish the two groups of carrier devices 11, the left carrier device 11 and the right carrier device 11 are named. The working principle is as follows: the external workpiece 100 in the form of a circular tube is placed on the clamping assembly 113 of the left carrier device 11, and the clamping assembly 113 fixes the circular tube. Under the driving of the first driving source of the left carrier device 11, the slide 111 moves along the first guide rail 10, so that the external workpiece 100 moves to the position below the printing head 2. The printing head 2 performs the first printing on the side surface of the external workpiece 100. After the first printing is completed, the first driving source drives the slide 111 to move away. At the same time, when the clamping assembly 113 of the left carrier device 11 moves to the position directly below the printing head 2 to work, the clamping assembly 113 of the right carrier device 11 performs the feeding.
