[0002] A packaging box is a device designed to facilitate transportation, loading and unloading, and storage.

[0003] Usually, marks are printed on the packaging boxes to summarize the packaging boxes. Traditionally, printing is done manually. In order to improve work efficiency, automatic printing devices were introduced later, such as Chinese patent application No. 201921726074.8. A printing device for corrugated paper packaging box production, including a workbench, an ink collection plate, a storage plate and a conveyor belt. The ink collection plate, the storage plate and the conveyor belt are all arranged in the inner cavity of the workbench.

DETAILED DESCRIPTION

[0024] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0025] Example:

[0026] like Figure 1-3 As shown, two side plates 2 are fixedly connected to the bottom plate 1, and a slide plate 5 is fixedly connected to the upper part of the two side plates 2. The slide plate 5 is provided with a first limit slide groove 6, and a rack 16 is slidably connected to the left and right limit slide groove 6. A threaded rod 4 is rotatably connected between the two side plates 2, and the rack 16 is threadedly connected to the outer wall of the threaded rod 4. A servo motor 3 is fixedly installed on the side plate 2, and the power output end of the servo motor 3 is connected to the threaded rod 4.

[0027] The side plate 2 is fixedly connected with a bearing seat 15, and the upper limit rotation connection of the bearing seat 15 is connected with a rotating column 18, and the top of the rotating column 18 is fixedly connected with a gear 19, and the gear 19 is meshed with the rack 16. The bottom of the rotating column 18 is fixedly connected with a disc 17, and the outer wall of the disc 17 is fixedly connected with a second connecting rod 20, and the side of the second connecting rod 20 away from the disc 17 is hinged with a hinge rod 21, and the side of the hinge rod 21 away from the second connecting rod 20 is hinged with an ink box 8, and the ink box 8 is slidably connected to the second limit slide groove 7 on the top of the bottom plate 1 in a front-back limit position. Ink is placed in the ink box 8.

[0028] The right end of the rack 16 is fixedly connected to the first connecting plate 11 , a hydraulic rod 12 is installed at the bottom of the first connecting plate 11 away from the rack 16 , and a printed board 13 is connected to the bottom telescopic end of the hydraulic rod 12 .

[0029] Two lifting plates 9 are fixedly connected to the bottom plate 1, and a packing box mounting plate 10 is fixedly connected between the upper parts of the two lifting plates 9. The packing box mounting plate 10 can be placed directly below the printing plate 13. A conveyor belt 14 is installed at the bottom of the packing box mounting plate 10. The left side of the conveyor belt 14 is placed at the bottom of the packing box mounting plate 10, and the right side is placed outside, which is used to convey the printed packing box. When the printing plate 13 moves from the top of the packing box mounting plate 10 to the top of the ink box 8, the ink box 8 just moves back and forth for a complete circle or multiple circles, which is used to mix the ink in the ink box 8 and facilitate ink dipping.

[0030] In the specific implementation, the packaging box is first placed on the packaging box mounting plate 10 in a good placement position. Then the servo motor 3 is started to drive the threaded rod 4 to rotate. Under the action of the thread and the limit, the rack 16 moves horizontally to the left. At this time, the rack 16 drives the printing plate 13 to move to the left and move to the top of the ink box 8. At this time, the rack 16 drives the gear 19 to rotate, and the gear 19 drives the rotating column 18 and the disc 17 to rotate. The disc 17 drives the ink box 8 to move forward and backward through a complete circle or multiple circles through the second connecting rod 20 and the hinged rod 21 so that the ink box 8 still returns to the initial position. At this time, the hydraulic rod 12 is started to make the printing plate 13 enter the ink box 8 for ink dipping, and then the hydraulic rod 12 is retracted, and the servo motor 3 is reversed to move the printing plate 13 to the top of the packaging box mounting plate 10. At this time, the hydraulic rod 12 is started to make the printing plate 13 print on the packaging box. After printing, the personnel observe whether the printing is successful. After confirming that the printing is successful, it is placed on the conveyor belt 14 to be transported to the preset position, and the printed seal is air-dried during transportation.
