Description

Technical Field

[0001] The utility model relates to the technical field of carton and paperboard processing, in particular to an ink printing device for carton and paperboard printing. Background Art

[0002] Printing is the technology of transferring the ink of the original manuscripts such as text, pictures, photos, anti-counterfeiting, etc. to the surface of paper, textiles, plastics, leather, PVC, PC and other materials through plate making, inking, pressurization and other processes to reproduce the original manuscript content in batches. Printing is the process of transferring the approved printing plate to the substrate through printing machinery and special ink.

[0003] Carton paperboard is one of the most widely used packaging products. Depending on the materials used, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. Before the carton is assembled, its surface is usually printed with some product advertisements or some relevant information about the products packaged inside.

[0004] An ink printing device is used during printing. The printing roller in the main ink printing device prints and dyes the carton board, and prints different printing patterns on the board.

[0005] Prior art such as the utility model with publication number CN209920760U, the utility model discloses a carton printing device, including a workbench, a first printing roller, a second printing roller and a servo motor, a guide frame is installed above the workbench, and a mounting sleeve is installed on the inner side of the guide frame, a support block is arranged on the inner side of the mounting sleeve, and a return spring and a roller are respectively installed on the support block, the return spring is located on the inner side of the mounting sleeve, and the support block is connected to the mounting sleeve through the return spring, a material storage cavity is arranged on the inner side of the mounting frame, and a coating sheet is arranged below the material storage cavity, and A reinforcing sheet is provided on the inner side of the coating sheet. The carton printing device utilizes the coating sheet made of textile cloth to evenly apply the ink in the storage cavity to the second printing roller, so that the second printing roller is convenient for printing on the paperboard and can prevent the occurrence of ink breakage or ink drying, thereby improving the stability of paperboard printing and indirectly reducing the defective rate of finished carton products. This solves the problem that the existing carton ink printing device is prone to ink breakage or ink drying after long-term printing, thereby causing unclear printed information, reducing the printing effect, and thus causing the defective rate of finished carton products to be too high, thereby increasing the production cost of the carton.

When the printing rollers 4 are rotating for printing, the coating member 5 can increase the ink on the printing rollers 4.

[0029] Specifically, the surface of the coating member 5 is fixedly connected with a motor 68, the output end of the motor 68 is fixedly connected with a gear 1 69, the side of the fixing ring 61 close to the gear 1 69 is fixedly connected with a gear 2 610, the gear 1 69 is meshingly connected with the gear 2 610, and when the motor 68 is turned on, the motor 68 can drive the fixing ring 61 and the connecting shaft 62 to rotate on the coating member 5 through the gear 1 69 cooperating with the gear 2 610, thereby realizing automatic adjustment.

[0030] Specifically, a limiting ring 64 is sleeved on the surface of the coating member 5, and a plurality of limiting holes 67 are opened on the surface of one side of the fixing ring 61 against the limiting ring 64. The limiting ring 64 is plugged into the inner wall of the limiting hole 67, and a pulling member 65 is slidably connected to the inner wall of the coating member 5, and the pulling member 65 is fixedly connected to the surface of one side of the limiting ring 64.

[0031] In this embodiment, after the motor 68 controls the fixed ring 61 to rotate and switch the printing roller 4, it can drive the limiting ring 64 to insert into the corresponding limiting hole 67 on the surface of the fixed ring 61 through the puller 65, thereby improving the overall stability effect after adjustment.

[0032] Specifically, a spring 66 is sleeved on the surface of the coating member 5, and both ends of the spring 66 are fixedly connected to the limiting ring 64 and the surface of the coating member 5 respectively.
