[0002] A corrugated box is a box made of corrugated cardboard. The longitudinal folds of the cardboard intersect with each other to form a reinforced structure, which improves the strength and compression resistance of the box. After the production of the corrugated box is completed, it is generally necessary to use a printing machine to print and spray the surface of the corrugated box.

However, the common carton positioning structure is not convenient for adjusting the positioning height. When positioning cartons of different thicknesses, too many positioning components need to be disassembled when adjusting the positioning structure, and the adjustment time is too long. Therefore, a corrugated box positioning mechanism and a printing machine are needed. Utility Model Content

[0011] Technical effects and advantages of the utility model:

[0012] (1) The device uses multiple limit pressing plates to fit the upper surface of the corrugated paper box to prevent the upper surface cardboard of the corrugated paper box from warping before printing on the printing machine body. When corrugated paper boxes of different thicknesses need to be positioned, if the corrugated paper box is thin, the U-shaped pushing plate is pushed downward by the provided pushing screw, so that the positioning connecting plate moves downward accordingly, thereby pushing the limit pressing plate downward, so that the limit pressing plate fits the upper surface of the thinner corrugated paper box. If the corrugated paper box is thicker, the pushing screw is rotated to move the pushing screw upward. At this time, the U-shaped pushing plate and the positioning connecting plate move upward under the push of the supporting spring, so that the limit pressing plate can fit the upper surface of the thicker corrugated paper box to adapt to the printing positioning of corrugated paper boxes of different thicknesses. This solves the problem that the common carton positioning structure is not convenient for adjusting the positioning height. When positioning cartons of different thicknesses, too many positioning components need to be disassembled when adjusting the positioning structure, and the required adjustment time is too long. It is difficult to fit the upper surface of corrugated paper boards of different thicknesses, and the applicability is poor.

[0013] (2) The device delivers the corrugated paper box to the bottom of the printing end of the printing machine body through the feed belt. When the corrugated paper box passes through the material guide assembly, the positioning guide roller is used to initially level the surface of the corrugated paper box.
