The loading and unloading assembly can not only push the carton forward, but also pull the carton backward.

[0044] In this embodiment, the adjustable pipe fitting specifically includes: a vertical cavity 26 opened inside the support plate 21, vertical grooves 27 symmetrically opened on the inner walls on both sides of the vertical cavity 26, an optical axis 28 movably connected between the two vertical grooves 27, and a guide wheel 29 rotatably connected to the outside of the optical axis 28, an exhaust pipe 30 is provided inside the vertical cavity 26, and one end of the exhaust pipe 30 passes through the guide wheel 29 and is connected to the negative pressure cavity 24, and the other end of the exhaust pipe 30 passes through the support plate 21 and is connected to the external vacuum pumping equipment.

[0045] In this embodiment, the lifting material blocking mechanism specifically includes: two second cylinders 32 fixed inside the first conveying roller 1, the top output shafts of the two second cylinders 32 are fixedly connected to a baffle 31, and a side of the baffle 31 is provided with a plurality of evenly distributed rotating grooves 33 along its length direction, and a guide roller 34 is rotatably connected inside the rotating groove 33. The setting of the lifting material blocking mechanism can limit the position of the carton when it passes by, thereby assisting the loading and unloading assembly to push the carton into the printing cavity 3.

[0046] In this embodiment, four evenly distributed third cylinders 35 are fixedly connected to the top surface of the printing cavity 3, and a printing plate 36 is fixedly connected to the output shaft at the bottom of the third cylinder 35. The printing plate 36 is used to print patterns on the surface of the carton.

[0047] The present application also discloses an automated packaging carton printing method, which is applied to an automated packaging carton printing device, comprising: placing a carton to be printed into a first conveyor roller 1, and during the placing process, the carton opening is directed toward one side of the first conveyor roller 1; the first conveyor roller 1 conveys the carton forward until the carton is blocked by a lifting material blocking mechanism; the loading and unloading components on one side of the first conveyor roller 1 deliver the carton into a printing cavity 3 of a printing box 2; a material receiving support mechanism receives the carton entering the printing cavity 3 and fills and tightens the carton; the four sides of the carton are printed in sequence, and after printing is completed, the carton is delivered to the second conveyor roller 37 through the loading and unloading components on one side of the second conveyor roller 37; the second conveyor roller 37 delivers the printed carton.

[0048] The working principle of the present invention is as follows: when in use, first, the carton to be printed is placed in the first conveyor roller 1, and the opening of the carton is directed toward one side of the first conveyor roller 1 during the placing process. Subsequently, the first conveyor roller 1 conveys the carton forward, and when the carton passes through the loading and unloading assembly, the camera 38 of the loading and unloading assembly collects the image of the carton and sends it to the background control terminal for identification. If it is identified that the opening of the carton is directed toward the right side of the first conveyor roller 1, the lifting and lowering material blocking mechanism close to the feeding end of the first conveyor roller 1 is operated to block the material, and if it is identified that the opening of the carton is not directed toward the right side of the first conveyor roller 1, the lifting and lowering material blocking mechanism does not operate to allow the carton to pass. When the passing carton passes through the second loading and lowering assembly, the camera 38 on it collects the image again for identification, and if it is identified that the opening of the carton is directed toward the left side of the first conveyor roller 1, the lifting and lowering material blocking mechanism away from the feeding end of the first conveyor roller 1 is operated to block the material, and if it is identified that the opening of the carton is not directed toward the left side of the first conveyor roller 1, the lifting and lowering material blocking mechanism does not operate to allow the carton to pass. The specific material blocking process of the lifting material blocking mechanism is as follows: the second cylinder 32 runs to extend the output shaft, and the baffle 31 rises from the gap of the first conveying roller 1 to block the advancing carton.

[0049] When the carton is blocked by the lifting material blocking mechanism, the first cylinder 22 of the loading and unloading assembly runs to extend the output shaft, and the negative pressure plate 23 pushes the carton forward to push it into the printing cavity 3 from the notch. During the process, the external vacuum equipment runs to extract the air in the negative pressure cavity 24 through the suction pipe 30, so that a negative pressure environment is formed inside the negative pressure cavity 24, and the carton is firmly sucked together with the through hole 25. In the process of the carton being pushed, the guide roller 34 in the rotating groove 33 reduces the friction resistance with the carton. At the same time, the suction pipe 30 is pulled out of the vertical cavity 26, and the optical axis 28 slowly rises along the vertical groove 27, while the guide wheel 29 and the suction pipe 30 rotate relative to each other.

[0050] After the carton is pushed into the printing cavity 3, the receiving block 8 of the receiving support mechanism is inserted into the carton to receive the carton. At this time, the driving member drives the various extrusion plates 17 to move synchronously, and then squeezes the rectangular airbag 16 to expand the round airbag 10 to further fill the carton. The external vacuum equipment stops running, and the first cylinder 22 retracts the output shaft. During the process, the carton is left on the receiving block 8, the negative pressure plate 23 returns to its initial position, and the suction pipe 30 also returns to its initial position under the gravity of the optical axis 28 and the wire wheel 29. Next, the third cylinder 35 directly above the carton runs to extend the output shaft, and the corresponding printing plate 36 moves down to print the first side of the carton. After the first side of the carton is printed, the stepper motor 5 runs to drive the rotating disk 6 to rotate 90 degrees counterclockwise in the horizontal plane, and the dual-axis motor 7 runs to drive the two material receiving blocks 8 to rotate 90 degrees in the vertical plane. At this time, the second side of the carton is facing upward, and the carton arrives directly below the second printing plate 36. Subsequently, the second printing plate 36 moves down to print the second side of the carton. After the second side of the carton is printed, the stepper motor 5 runs again to drive the rotating disk 6 to rotate 90 degrees counterclockwise in the horizontal plane, and the dual-axis motor 7 runs again to drive the two material receiving blocks 8 to rotate 90 degrees in the vertical plane. At this time, the third side of the carton is facing upward, and the carton arrives directly below the third printing plate 36. Subsequently, the third printing plate 36 moves down to print the third side of the carton. At the same time, another idle material receiving block 8 is aligned with the first conveying roller 1 to carry out the next material receiving and print the first side of the next carton. After the third side of the first carton is printed, the first side of the second carton is also printed, and the stepper motor 5 is operated again to drive the rotating disk 6 to rotate 90 degrees counterclockwise in the horizontal plane, and the dual-axis motor 7 is operated again to drive the two receiving blocks 8 to rotate 90 degrees in the vertical plane. At this time, the fourth side of the first carton is facing upward, and the second side of the second carton is facing upward, and then printed by the corresponding printing plate 36. Then, the first carton that has completed the printing on four sides is taken away by the loading and unloading assembly, so that the corresponding receiving block 8 is idle, and when the second carton rotates next time, this idle receiving block 8 is aligned with the first conveying roller 1 again to receive the next material and print the first side of the third carton, and so on to complete the printing of all cartons.

[0051] It should be noted that there is a certain gap between the receiving block 8 and the carton when it is just connected to the carton. This gap is for the convenience of inserting the receiving block 8 into the carton. After the carton is retained by the receiving block 8, the specific process of the driving part running to fill the carton is as follows: the annular electromagnet 20 close to the rotating disk 6 is powered on to generate magnetism, and the energized annular electromagnet 20 attracts the corresponding annular iron block 19 to approach itself through magnetic adsorption, thereby causing the sleeve 14 to move along the shaft 13 away from the rotating disk 6. During the process, the sleeve 14 drives each extrusion plate 17 to move synchronously, and the extrusion plate 17 squeezes the rectangular airbag 16 so that the gas in the rectangular airbag 16 enters the circular airbag 10 through the pipe 18, and the circular airbag 10 is inflated to further fill the interior of the carton, and can provide support when printing on the four sides of the carton in sequence, which is convenient for use.

[0052] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.

[0053] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
