The invention aims to provide a packaging carton watermark printing device, when in use, by arranging a movable printing plate 7 and a printing frame 6, when a user uses the watermark printing device to print a packaging carton paperboard, the user can select a corresponding splicing printing plate 36 according to a printing pattern of the packaging carton paperboard, simultaneously select a splicing clamping groove 37 at a corresponding position on the movable printing plate 7 according to a printing position, then clamp the splicing printing plate 36 on the movable printing plate 7 by using the splicing clamping groove 37 to fix the splicing printing plate 36, simultaneously, the user pushes a fixed pull handle 35 to enable the fixed pull handle 35 to drive the movable printing plate 7 to move in the printing frame 6 by matching with a sliding clamping plate 33 and a sliding groove 34, transversely slide the movable printing plate 7 to adjust the printing position of the splicing printing plate 36 on the movable printing plate 7, and when in printing operation, a pigment in a pigment tank 14 is guided to the movable printing plate 7 by using a material conveying pipe 15, the transmission gear 29 is driven by the second motor 21 to drive the roller of the movable clamping seat 20, so that the movable clamping seat 20 drives the inclined plane scraper 18 and the pushing scraper 19 to move transversely, the inclined plane scraper 18 and the pushing scraper 19 push the pigment on the movable printing plate 7, the pigment penetrates through the splicing printing plate 36 and is coated on the paper box board, the printing operation is completed, and the movable printing plate 7 and the printing frame 6 are arranged to be matched with the splicing printing plate 36, so that the packaging paper box watermark printing device has a movable combined printing structure, and the flexibility of the packaging paper box watermark printing device in use is effectively improved;

by arranging the movable bottom plate and the elastic buckle 5, when a user utilizes the watermark printing device to fix the packaging box paper board, the user can pull the movable bottom plate to match with the side-rotating caster 30 and the sliding clamping seat 40 to move the movable bottom plate out of the lower part of the printing frame 6, the friction force generated when the movable bottom plate moves can be reduced by utilizing the side-rotating caster 30, so that the moving operation of the movable bottom plate is smoother, meanwhile, the elastic buckle 5 is pulled to adjust the distance between the elastic buckle 5 and the elastic buckle 5, so that the packaging box paper boards with different sizes can be placed between the elastic buckle 5 and the elastic buckle 5, the paper box board is placed between the elastic buckle 5 and the elastic buckle 5, the elastic buckle 5 is pulled by utilizing the spring pin 32, so that the elastic buckle 5 is tightly clamped on the side edge of the paper box board to fix the paper box board, and the phenomenon of lateral movement of the paper box board in, the arrangement of the movable bottom plate and the elastic buckle 5 is utilized, so that the watermark printing device has a fixed adjusting structure, the watermark printing device can fix the carton boards with different sizes, and the application range of the watermark printing device is improved;

by arranging the threaded snap ring 39 and the threaded rod 12, when a user uses the watermark printing device to print a certain number of carton boards, the user starts the first motor 10 to enable the first motor 10 to drive the threaded rod 12 to rotate by using the fluted disc, so that the threaded rod 12 drives the movable connecting plate 13 to longitudinally move on the lifting clamping table 11 by using the threaded snap ring 39, the lifting clamping table 11 is lifted, the lifting clamping table 11 is matched with the sliding clamping seat 40 to drive the printing frame 6 to move upwards, thereby adjusting the distance between the printing frame 6 and the movable bottom plate, so that a certain number of carton boards can be placed between the printing frame 6 and the movable bottom plate, when the watermark printing device continuously prints the carton boards, the printing frame 6 is driven to move downwards to enable the printing frame 6 to be in contact with the carton boards on the movable bottom plate, after the printing of a single piece of carton boards is finished, the printing frame 6 moves upwards, and the printed carton boards are drawn out, after the printing frame 6 moves downwards, continuous printing operation is carried out, and by means of the arrangement of the threaded snap ring 39 and the threaded rod 12, the packaging carton watermark printing device is provided with a lifting printing structure, so that continuous printing operation can be carried out, and the working efficiency of the packaging carton watermark printing device is improved;

by arranging the inclined plane scraper 18 and the pushing scraper 19, during printing operation, the second motor 21 is used for driving the transmission gear 29 to drive the roller of the movable clamping seat 20, so that the movable clamping seat 20 drives the inclined plane scraper 18 and the pushing scraper 19 to transversely move, the inclined plane scraper 18 and the pushing scraper 19 are in contact with the spliced printing plate 36, double smearing operation can be performed on the spliced printing plate 36 by using the inclined plane scraper 18 and the pushing scraper 19, pigment passes through the spliced printing plate 36 and is smeared on a paper box plate, smearing of the pigment is more uniform, and the inclined plane scraper 18 and the pushing scraper 19 are arranged, so that the packaging paper box watermark printing device has an auxiliary printing structure and the printing effect of the packaging paper box watermark printing device is improved.
