Description

Technical Field

[0001] The utility model relates to the technical field of paper box printing, in particular to a paper box auxiliary turning mechanism for paper box printing. Background Art

[0002] Carton printing refers to printing the required text, patterns and other information onto the surface of the carton. It generally includes process flows such as plate mounting, inking, embossing, and paper feeding. Carton printing generally includes single printing, printing slotting, die-cutting, printing slotting, die-cutting, box gluing and linked production lines. Since the printing of carton requires printing on multiple sides, a flipping mechanism is required to flip the carton so that both sides of the carton can be printed.

[0003] For example, the Chinese utility model provides "a paper box auxiliary turning mechanism for paper box printing", announcement number: CN220826397U, which includes a U-shaped frame, a first conveyor belt is installed on one side of the U-shaped frame, a support plate is fixed on the side of the U-shaped frame away from the first conveyor belt, a U-shaped plate is arranged on the upper surface of the support plate, and a second conveyor belt is installed inside the U-shaped plate. In the utility model, a U-shaped frame, a first conveyor belt, a second conveyor belt, a central axis, four flaps and an electric telescopic rod are arranged, and an anti-slip component is installed on each flap. After the first conveyor belt conveys the paper box to the flap surface, the paper box can be pressed and fixed by the anti-slip component. When the central axis drives the paper box to turn 180° and move to the side of the second conveyor belt, the electric telescopic rod drives the second conveyor belt to move, and uses the pressing component to press the paper box again, and finally the paper box is conveyed by the second conveyor belt.

[0028] In the present technical scheme, the setting of the rotating roller 16 facilitates the paper box to slide along the surface of the flip plate 8. The setting of the support plate 11 achieves the purpose of stably supporting the rotating shaft 17 to prevent the rotating shaft 17 from tilting due to force.

[0029] The working principle of the utility model is as follows: through the setting of the first belt conveyor 1, the paper box to be turned over can be transported to the turning plate 8, and when the paper box enters the turning plate 8, the driving motor 4 is started to drive the rotating shaft 17, the turning plate 8 and the first synchronous wheel 12 to rotate.

The rotation of the rotating drum 21 can drive the two groups of movable guide rods 19, the movable frame 5, the supporting spring 15 and the straightening splint 9 to move toward each other through the spiral guide groove 22. Under the action of the movement of the straightening splint 9, the paper box on the top of the second belt conveyor 6 can be pushed, so that the paper box can be straightened and placed in the middle end of the second belt conveyor 6, thereby achieving the effect of effectively centering the paper box after it is turned over, effectively avoiding the subsequent printing operation affected by the improper placement or position displacement after the paper box is turned over, and facilitating the use of personnel.
