"Up", "down", "left", "right" and the like are only used to indicate relative position relationships. When the absolute position of the object being described changes, the relative position relationship may also change accordingly.

[0032] The first aspect of the present invention provides a feeding assembly for a carton printing machine, such as Figure 1-5 As shown, it includes a conveyor belt 1 arranged on the side of the carton printing machine, a feed box 2 is provided on the conveyor belt 1, and a protective cover 3 is provided on the side of the feed box 2 in the feeding direction of the conveyor belt 1. The feeding assembly also includes:

[0033] The leveling top frame 4 is arranged above the conveyor belt 1;

[0034] The leveling chassis 5 is rotatably arranged on both sides of the protective cover 3 via a rotating shaft;

[0035] A driving mechanism for driving the leveling top frame 4 to move up and down, and driving the leveling bottom frame 5 to flip over.

[0036] In this embodiment, the driving mechanism includes:

[0037] The driving motor 6 is mounted on the top of the protective cover 3 through a mounting bracket 7. The mounting bracket 7 is provided with a guide groove 8 in the vertical direction.

[0038] Cam 9, cam 9 is installed on the driving motor 6;

[0039] The lifting frame 10 is slidably mounted on the protective cover 3 and guided in the guide groove 8. The top of the lifting frame 10 cooperates with the outer edge of the cam 9. The middle of the lifting frame 10 is sleeved with a spring 11. The upper end of the spring 11 abuts against the lifting frame 10, and the lower end of the spring 11 abuts against the protective cover 3. The leveling frame 4 is installed at the lower end of the middle part of the lifting frame 10.

[0040] Rack 12, the rack 12 is installed at the lower ends of both sides of the lifting frame 10;

[0041] The gear 13 is mounted on the rotating shaft and meshes with the rack 12 .

[0042] In this embodiment, if Figure 2 As shown, the ends of the leveling top frame 4 and the leveling bottom frame 5 are both triangular structures. The triangular structures of the leveling top frame 4 and the leveling bottom frame 5 are both made of flexible materials and correspond to each other in the vertical direction.

[0043] In this embodiment, when in use, the cartons to be printed are stacked in the feed box 2, and the bottom carton is conveyed in the feeding direction by the conveyor belt 1. Under the limitation of the horizontal guide roller 15, only one carton enters the feeding assembly. Under the guidance of the guide side wheels 14 on both sides on the side ends of the carton, the carton is fed in a centered state, and this process also activates the drive mechanism;

[0044] Driven by the output end of the drive motor 6 in the drive mechanism, the cam 9 rotates at a constant speed. When the outer edge of the small diameter of the cam 9 pushes against the upper surface of the lifting frame 10, it pushes the lifting frame 10 to move downward. At this time, the spring 11 is compressed. As the outer edge of the small diameter of the cam 9 rotates and separates from the upper surface of the lifting frame 10, the spring 11 returns to its original position under its own elastic force, and then pushes the lifting frame 10 to move upward, thereby realizing the up and down reciprocating motion effect of the lifting frame 10.

[0045] When the lifting frame 10 is descending, it will drive the leveling frame 4 at the lower end to descend synchronously, and will also drive the gear 13 to rotate through the racks 12 on both sides of its lower end, and drive the leveling frames 5 on both sides to flip inward synchronously through the rotating shaft. Since the ends of the leveling frame 4 and the leveling frame 5 are both triangular structures, and the triangular structures are both made of flexible materials, the leveling frame 4 and the leveling frame 5 can simultaneously level the top and bottom of the passing cartons, and further enhance the centering and anti-skew feeding effect of the cartons.

[0046] In this embodiment, if Figure 2 As shown, it also includes guide side wheels 14, there are at least two guide side wheels 14, and the two guide side wheels 14 are respectively rotatably arranged on both sides of the inner wall of the protective cover 3 to ensure the centering effect of the carton transportation.

[0047] In this embodiment, if Figure 2 As shown, it also includes a horizontal guide roller 15, which can be adjusted inside the protective cover 3. The height of the horizontal guide roller 15 can be adjusted in time according to the thickness of the carton to be transported, making the feeding assembly more adaptable.

[0048] In this embodiment, if Figure 2 As shown, the horizontal guide roller 15 is made of flexible material, and a material transfer channel is set between the horizontal guide roller 15 and the conveyor belt 1. The gap of the material transfer channel is greater than the cardboard thickness of one carton and less than the cardboard thickness of two cartons, so as to avoid the situation where the conveyor is jammed due to the simultaneous feeding of multiple cartons.
