The pushing blocks 16 are slidably arranged in the guiding groove 15. By placing the carton to be processed on the guiding frame 2 and using the conveyor belt 4 to drive the pushing block 16 structure to rotate in a cycle, the carton can be pushed to the printing frame 5, realizing automatic feeding and improving the processing efficiency of the equipment.
[0019] A printing frame 5 is fixedly connected to the side of the conveying frame 1, a second motor 6 is fixedly installed on the side of the printing frame 5, a working groove is opened on the side of the printing frame 5, and a synchronous placement block 7 is fixedly installed at the top of the working groove. A double-sided printing roller 8 is fitted and installed on the top of the synchronous placement block 7. The output end of the second motor 6 is fixedly connected to a first semi-circular block 17, and a threaded hole 18 is opened at the top of the semi-circular block. A second semi-circular block 19 is fixedly connected to the side of the bottom printing roller of the double-sided printing roller 8. A curved groove 20 is opened on the side of the second semi-circular block 19, and a reinforcing curved block 21 is arranged on the side of the curved groove 20. A fastening bolt 22 is fitted and installed on the side of the reinforcing curved block 21. The first semi-circular block 17 and the second semi-circular block 19 are combined and connected in a matching manner, and the fastening bolt 22 passes through the second semi-circular block 19 and is inserted and fixed in the threaded hole 18 at the top of the first semi-circular block 17. The fastening bolt 22 connects the first semi-circular block 21 and the second semi-circular block 19 in series, enabling the second motor 6 to drive the double-sided printing roller 8 structure to rotate synchronously. The installation and insertion are fast, ensuring the connection stability and avoiding the phenomenon of printing distortion.
[0020] One end of the double-sided printing roller 8 away from the synchronous placement block 7 is connected with a docking block 9. A rotating plate 10 is inserted and installed on the side of the docking block 9. The side of the rotating plate 10 is rotatably connected with an assembly box 11. Two groups of tension gears 12 are rotatably installed at the inner bottom of the assembly box 11, and a transmission chain 13 is meshed and connected to the side of the tension gear 12. A card slot 37 is fixedly installed at the top of the assembly box 11. Multiple docking groove blocks 14 are fixedly installed at the top of the transmission chain 13, and the docking groove blocks 14 can be inserted and matched with the docking block 9. By starting the third motor 27, the rotating plate 10 is driven to rotate. The docking block 9 at the bottom of the printing roller structure with different patterns selected in the rotating plate 10 and the assembly box 11 is magnetically adsorbed and fixed, and then rotated and placed in the printing area to achieve the effect of automatically placing and replacing the double-sided printing roller 8. A third motor 27 is fixedly installed at the bottom of the assembly box 11. The output end of the third motor 27 is fixedly connected with a square rod 28, and the rotating plate 10 is slidably arranged on the side of the square rod 28. The third motor 27 can not only drive the rotating plate 10 structure to rotate through the square rod 28, but also the rotating plate 10 can slide on the side of the square rod 28.
[0021] A fitting block 29 is fixedly connected to the top of the docking groove block 14. Two groups of limiting groove columns 30 are arranged at the top of the docking groove block 14. A pulley 31 is installed at the bottom of the docking groove block 14. The pulley 31 is built inside the card slot 37. Two groups of sliding rods 32 are fixedly installed inside the limiting groove column 30, and the side of the end of the sliding rod 32 is slidably connected with a fixing head 33. During the insertion and matching process of the docking block 9 and the docking groove block 14, the fitting groove 35 and the fitting block 29 are clamped, the limiting groove column 30 and the fixing groove 36 are clamped, and the fixing head 33 inside the limiting groove column 30 will slide on the side of the sliding rod 32 under the push of the tension spring 34, and penetrate the docking block 9 structure through the fixing groove 36 to complete the connection between the docking block 9 and the docking groove block 14. The connection structure is reasonably designed to ensure quick docking and installation. A tension spring 34 is sleeved on the side of the sliding rod 32. The tension spring 34 is built inside the limiting groove column 30, and the tension spring 34 is fixedly connected with the fixing head 33. The pulley 31 slides in the card slot 37, which provides a support point while ensuring the stable output of the docking groove block 14, avoids the overall weight of the double-sided printing roller 8 structure pressing on the top of the transmission chain 13, reduces the force and wear of the equipment, and improves the experimental life. The fitting block 29 structure and the limiting groove column 30 structure at the top of the docking groove block 14 can play a role of limiting connection during the assembly process, which is not only convenient for installation, but also ensures that the double-sided printing roller 8 is stably located on the top of the docking groove block 14 during the process of replacing the printing roller driven by the rotating block structure.
[0022] On the side of the rotating plate 10, multiple damping rods 24 are provided. The damping rods 24 connect the two side rotating plates 10 into a whole. The bottom of the damping rod 24 is fixedly connected to the square rod 28 through a connecting piece. An electromagnetic block 25 is provided on the side of the rotating plate 10. An adaptation groove 35 is opened at the bottom of the docking block 9. The adaptation groove 35 is engaged with the adaptation block 29. A fixing groove 36 is opened at the bottom of the docking block 9, and the fixing groove 36 can be slidably inserted and matched with the fixing stud 33 and the top block 26. After the electromagnetic block 25 is powered on, it can be magnetically connected to the iron block provided on the side of the docking block 9. The electromagnetic block 25 drives the rotating plate 10 to slide on the side of the square rod 28. After power-off, under the push of the damping rod, the rotating plate 10 slides in the reverse direction and disengages from the docking block 9. A top block 26 is fixedly provided on the side of the rotating plate 10. After the electromagnetic block 25 is powered on, the top block 26 on the side of the rotating plate 10 will be inserted into the fixing groove 36 opened on the side of the docking block 9. At the same time, the fixing stud 33 inserted in the fixing groove 36 is pushed out by the top block 26. The top block 26 replaces the fixing stud 33 to complete the fixing and limiting operation with the docking block 9. After the electromagnetic block 25 is powered off, under the push of the damping rod 24 in the rotating plate 10, the top block 26 withdraws from the fixing groove 36. The fixing stud 33 slides on the side of the sliding rod 32 again under the push of the tension spring 34 and is inserted into the fixing groove 36 again, eliminating the need for manual secondary assembly and enabling mechanical automatic replacement and disassembly.
[0023] During specific use: First, place the flattened carton on the guiding frame 2, start the first motor 3 to drive the conveyor belt 4 to work. The conveyor belt 4 drives the pushing block 16 structure to rotate cyclically, which can push the carton at the bottom of the guiding frame 2 to move onto the printing frame 5 structure, realizing automatic feeding. When the carton reaches the printing frame 5 structure, the first semi-circular block 17 and the second semi-circular block 19 are connected in series through the fastening bolt 22, enabling the second motor 6 to drive the double-sided printing roller 8 to rotate. Moreover, the two groups of printing rollers of the double-sided printing roller 8 are connected through gear meshing. When the flattened carton sheet passes through the sandwich of the double-sided printing roller 8, the double-sided printing roller 8 simultaneously completes the printing operations on the top and bottom of the carton. When it is necessary to replace the printing roller with a different pattern, it is necessary to ensure that the required printing roller with a different pattern is installed in the assembly box 11. Multiple docking groove blocks 14 are fixedly installed at the top of the transmission chain 13, and the docking groove blocks 14 can be inserted and matched with the docking card blocks 9. During the insertion and matching process of the docking card blocks 9 and the docking groove blocks 14, the matching groove 35 and the matching block 29 are clamped, the limiting groove column 30 and the fixing groove 36 are clamped, and the fixing column head 33 inside the limiting groove column 30 will slide on the side of the sliding rod 32 under the push of the tension spring 34 and penetrate the docking card block 9 structure through the fixing groove 36, completing the connection between the docking card block 9 and the docking groove block 14, that is, completing the installation of the printing roller. During the process of replacing the printing roller, the transmission chain 13 drives the docking groove block 14 and the printing roller assembly on its top to move. The pulley 31 at the bottom of the docking groove block 14 slides in the card slot 37 to ensure the stable transportation of the docking groove block 14. When the required printing roller is displaced to the replacement area where the third motor 27 is located, start the third motor 27. The third motor 27 drives the rotating plate 10 to rotate. The rotating plate 10 moves to both sides of the docking card block 9, and the electromagnet 25 is energized. The top block 26 on the side of the rotating plate 10 will be inserted into the fixing groove 36 opened on the side of the docking card block 9. At the same time, the fixing column head 33 inserted in the fixing groove 36 is pushed out by the top block 26, and the top block 26 replaces the fixing column head 33 to complete the fixed limiting operation with the docking card block 9. Rotate the rotating plate 10 again, horizontally place the double-sided printing roller 8 on the top of the synchronous placement block 7, and adjust the accurate connection of the semi-circular notch connection surfaces of the first semi-circular block 17 and the second semi-circular block 19 to ensure the stable transmission between the second motor 6 and the double-sided printing roller 8. Repeat the above operations to complete the replacement operation of the double-sided printing roller 8.
[0024] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
