DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-4, the present utility model provides a technical solution: a four-color overprint phase adjustment conveying mechanism for cardboard water-based ink printing, including a front-end paper feeding phase adjustment device 1 and a hierarchical transmission device 2. The front-end paper feeding phase adjustment device 1 is arranged at the very front of the hierarchical transmission device 2. There are multiple hierarchical transmission devices 2, which are arranged in sequence. A workbench 3 is arranged on the front-end paper feeding phase adjustment device 1. The workbench 3 is installed on a frame 4. Multiple conveying roller wheels 5 are arranged on the workbench 3. The conveying roller wheels 5 are driven by a belt to be connected with a vacuum servo motor. The vacuum servo motor is installed inside the frame 4. A phase adjuster 7 is installed on the inner side wall of the rear side of the frame 4 through a bracket 6. The phase adjuster 7 enables the device to control the stable conveyance of cardboard of different sizes, and the printed position meets the production requirements, thereby controlling the printing accuracy.

[0018] Specifically, the phase adjuster 7 is provided with a slot hole 8, a bolt 9 and an acting hole 10. The bolt 9 is installed in the slot hole 8. The slot hole 8 is opened on the side surface of the phase adjuster 7. The acting hole 10 is arranged on the circumferential surface of the phase adjuster 7. The other side of the phase adjuster 7 is connected with a ball screw 11 through a belt provided.

[0019] In addition, an adjusting frame 12 is arranged above the workbench 3. The surface of the adjusting frame 12 is threadedly connected with the ball screw 11. Both ends of the ball screw 11 are connected with the frame 4. Guide rods 13 are arranged on both sides of the ball screw 11. The guide rods 13 are slidably connected with the adjusting frame 12. The rotation of the ball screw 11 drives the adjusting frame 12 to displace, so as to control the distance size. And during the adjustment process, the stability can be increased through the guide rods 13.

[0020] Secondly, a guide plate 14 is arranged on the hierarchical transmission device 2. A roller press wheel 15 is arranged above the guide plate 14. The roller press wheel 15 is movably arranged on the hierarchical transmission device 2. An extrusion shaft 16 is arranged at the rear side of the roller press wheel 15. A pressing wheel 17 is fixedly arranged on the extrusion shaft 16.

[0021] When the present utility model is specifically implemented: First, place the cardboard to be processed on the workbench 3. Driven by multiple conveying roller wheels 5, the cardboard is transported. In order to ensure the stable conveyance of cardboard of different sizes, loosen the bolt 9 on the phase adjuster 7. Under the effect of the acting hole 10, one side of the phase adjuster 7 rotates, and the bolt 9 changes its position in the slot hole 8, thereby changing the position of the adjusting frame 12, so as to adapt to the conveyance of cardboard of different sizes to the subsequent hierarchical transmission device 2. And under the action of the roller press wheel 15 and the pressing wheel 17, effective conveyance is carried out at each level, so that the printed position meets the factory requirements, there is no phenomenon of position deviation, and the printing quality is improved.

[0022] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
