Specific implementation mode

[0023] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without making creative efforts shall fall within the protection scope of this application.

[0024] Please refer to Figures 1-4 , a corrugated cardboard intelligent flexographic printing mechanism in this embodiment includes a frame 1, on which a flexible printing roller 2 is rotatably installed. The flexible printing roller 2 is driven by multiple groups of rollers and a screen plate is provided for printing, and full-automatic printing processing is realized through an intelligent control terminal.

[0025] Embodiment 1: In this embodiment, a fixed rod 3 is fixedly installed on the frame 1, a sliding sleeve 4 is slidably installed outside the fixed rod 3, and a roller 5 is fixedly installed on the sliding sleeve 4. The roller 5 is attached to the corrugated cardboard to limit the front and back offset of the corrugated cardboard.

[0026] It should be noted that a positioning structure is provided on the frame 1. The positioning structure includes a support frame 7 fixedly installed on the frame 1, a fixing plate 6 is fixedly installed on the support frame 7, a first side plate 8 and a second side plate 9 are hinged on one side surface of the fixing plate 6 through door hinges. Both the second side plate 9 and the first side plate 8 include two. The two first side plates 8 and the second side plate 9 are located on both sides of the corrugated paper and are used to guide the transmission of the corrugated paper.

[0027] In this embodiment, a connecting sleeve 11 is connected between the two second side plates 9, so that the second side plates 9 are parallel to the fixing plate 6. Limiting plates 10 are fixedly installed on the inner side walls of the second side plates 9 and the first side plates 8. The limiting plates 10 are arc-shaped and extend towards the inside of the first side plates 8 or the second side plates 9, and are used to guide the passing corrugated cardboard boxes, so that the corrugated cardboard boxes can move to the middle position to complete positioning.

[0028] Embodiment 2: In this embodiment, a connecting plate 22 extending to the outside of the connecting sleeve 11 is slidably installed inside the connecting sleeve 11. The connecting plate 22 is fixedly connected to the second side plate 9. A cam 12 is rotatably installed in the middle of the connecting sleeve 11. A connecting post 13 is fixedly installed at one end of the connecting plate 22 located inside the connecting sleeve 11. A connecting rod 14 is rotatably installed between the connecting post 13 and the cam 12. By rotating the cam 12, the relative distance between the two connecting plates 22 can be adjusted.

[0029] It should be noted that a ratchet 15 is also fixedly installed at the center of the cam 12. A slider 17 is slidably installed on the inner wall of the connecting sleeve 11. A ratchet tooth 19 that meshes unidirectionally with the ratchet 15 is fixedly installed on the slider 17. Through the meshing of the ratchet tooth 19 and the ratchet 15, the cam 12 can achieve unidirectional rotation. The axis core of the ratchet 15 extends through to the outside of the connecting sleeve 11, so that the cam 12 can be easily rotated and adjusted.

[0030] In this embodiment, a positioning seat 16 is fixedly installed on the inner wall of the connecting sleeve 11. A sliding rod 18 that is slidably connected to the positioning seat 16 is fixedly installed on the slider 17. Through the sliding of the sliding rod 18 relative to the positioning seat 16, the sliding of the slider 17 is stabilized.

[0031] In this embodiment, a return spring 20 is fixedly installed between the slider 17 and the positioning seat 16. The return spring 20 pushes the slider 17 against the ratchet 15, thereby realizing the unidirectional rotation limitation of the ratchet 15.

[0032] It should be noted that an adjusting rod 21 that extends through to the outside of the connecting sleeve 11 is fixedly installed on the slider 17. By sliding the adjusting rod 21, the meshing limitation of the ratchet tooth 19 on the ratchet 15 can be released.

[0033] The working principle of the above embodiments is as follows:

[0034] The axle core part extending to the outside of the connecting sleeve 11 by rotating the ratchet wheel 15 pulls the cam 12 to rotate and adjust the position. When the cam 12 rotates, it drives the connecting rod 14 to swing. When the connecting rod 14 swings, it pushes the two connecting posts 13 to make the connecting plate 22 adjust the distance between the two second side plates 9. At this time, when the corrugated cardboard passing through the second side plate 9 is offset from the center at the initial position, it first contacts the second side plate 9, and then is squeezed to the center position by the limiting plate 10. The centered corrugated paper is positioned by rolling through the roller 5, so as to ensure the accurate positioning of the corrugated paper by the rolling brush during processing.
