During the printing process, the oil pump 20 The ink inside the ink cartridge 15 is extracted and then sprayed onto the outer wall of the printing roller 11 by the inkjet device 18, and the scraper 16 scrapes off the excess ink on the outer wall of the printing roller 11. When the printing material is used up, the limit ring 23 can be rotated to move it on the rotating rod 21 to release the fixation of the material tube, and then one end of the fixing rod 22 is pushed to rotate it, and new printing material is replaced and the fixing rod 22 and the limit ring 23 are reset and fixed to avoid deviation during the printing process. At the same time, the material replacement is convenient. At this time, the hollow tube of the printing material will also limit the fixing rod 22, so that the fixing rod 22 is stuck on the rotating rod 21 to prevent it from falling off the rotating rod 21 during rotation.
