In the present embodiment, the transfer mechanism transfers the rotary body in a linear manner; the apparatus further comprises a frame 100 and a first mounting beam 101 and a second mounting beam 102; the first mounting beam 101 and the second mounting beam 102 are disposed on the rack 100 in a straddling manner, the transmission mechanism 5 is disposed on the rack 100 and located below the first mounting beam 101 and the second mounting beam 102, and the first mounting beam 101 and the second mounting beam 102 are sequentially arranged along a transmission direction of the transmission mechanism 5. The first mounting beam 101 is used for mounting the clamping feeding mechanism 2; the second mounting beam 102 is used to mount the printing mechanism 4. The rotary clamping mechanism 3 is disposed on the frame 100 between the transport mechanism 5 and the printing mechanism 4.

The invention firstly adopts the clamping and feeding mechanism 2 to clamp two ends of the rotating body 108 and position the rotating body 108, and when in the clamping process, the rotating body 108 can be positioned as long as the two ends of the clamping and feeding mechanism 2 are positioned; the rotating body 108 is positioned during feeding, and the printing precision of the rotating body 108 can be ensured only by ensuring that the rotating body 108 does not shake in the subsequent printing process; furthermore, the rotating clamping mechanism 3 is adopted to clamp the rotating body 108, drive the rotating body 108 to move and clamp two ends of the rotating body 108, so that the two ends of the rotating body 108 limit the rotating body 108 in the rotating process, the possibility of shaking of the rotating body 108 during rotation is further reduced, further, the printing precision of the rotating body 108 is ensured, and the printing effect is improved. Compared with the unilateral clamping rotating body 108 in the prior art, the unilateral clamping rotating body has the advantages that bilateral clamping is adopted in all carrying, so that the stability is high, and the printing quality is high; the technical problem that printing equipment for printing on the periphery side in the prior art is poor in printing effect is solved; has high printing quality.

The transport mechanism 5 transports the printing medium at a predetermined speed, preferably 5 meters per second, to transport the rotating body, specifically, depending on the size, specification, dimensions, etc. of the rotating body.
