[0002] The cardboard printing slotting die-cutting machine is a carton production auxiliary device that integrates paper feeding, printing and slotting die-cutting. It has been widely used in the field of packaging machinery. When the existing cardboard printing slotting die-cutting machine is used, first the machine body is powered on and started, then the cardboard is placed on the placement table, and then the cardboard is moved manually to align the cardboard with the paper inlet. After the alignment is completed, the cardboard is pushed into the machine body for printing and slotting die-cutting. After printing and slotting die-cutting are completed, the cardboard can be discharged from the paper outlet.

[0003] During the operation of the existing cardboard printing, slotting and die-cutting machine, it takes a lot of manpower and time to manually move the cardboard and adjust its position. At the same time, the efficiency of manually pushing the cardboard to the inside of the paper inlet is low, thereby reducing the overall processing efficiency of the cardboard. In view of this, we propose a cardboard printing and die-cutting device for carton making. Utility Model Content

Two groups of hydraulic cylinders 1 602 are provided at the bottom of the inner side of the fixed frame 601. The movable end of the hydraulic cylinder 1 602 is connected to a support plate 603, wherein the support plate 603 and the auxiliary groove 604 are integrally formed. The support plate 603 and the fixed frame 601 form a lifting structure through the hydraulic cylinder 1 602. A group of auxiliary grooves 604 are symmetrically opened inside the support plate 603. A limiting frame 605 is fixed on the side of the fixed frame 601 away from the body 1. A hydraulic cylinder 2 606 is provided in the middle of the limiting frame 605. A push rod 607 is connected to the movable end of the hydraulic cylinder 2 606. Furthermore, the push rod 607 forms a telescopic structure with the limiting frame 605 through the hydraulic cylinder 2 606. The height of the push rod 607 is higher than the height of the top cardboard 7. The utility model effectively drives the support plate 603 to move upward through the hydraulic cylinder 1 602, thereby driving several cardboards 7 on the surface of the support plate 603 to move upward, so that the topmost cardboard 7 reaches the height of the push rod 607, and then the hydraulic cylinder 2 606 effectively drives the push rod 607 to move horizontally, so that the push rod 607 pushes the top cardboard 7 to move horizontally until the cardboard 7 reaches the conveyor belt surface of the conveyor belt assembly 2, thereby realizing the rapid transportation of the cardboard 7, and the transportation of other subsequent cardboards 7 is similar.

[0025] It is worth noting that the limiting structure 5 includes an electric push rod 501, which is engaged with the inner side of the body 1, and the movable end of the electric push rod 501 is connected to the limiting plate 502.
