[0015] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0016] Example 1 Please refer to Figure 1-5 As shown, an automated printing device for cardboard boxes includes a workbench 1. A mounting plate 7 is fixed to the top of one end of the workbench 1, and a hydraulic rod 8 is mounted on one side of the mounting plate 7. The output end of the hydraulic rod 8 is connected to a screen printing box 3, and the screen printing box 3 has an internal cavity 15. A rotary motor 9 is mounted on the front surface of the screen printing box 3, and the output end of the rotary motor 9 is connected to a screw 10 that penetrates into the cavity 15. A sliding plate 19 is slidably connected inside the cavity 15. The two sides of the sliding plate 19... A gear 21 is rotatably connected to the side. Tooth grooves 13 are provided on both sides of the cavity 15. The bottom of the tooth groove 13 is provided with teeth that mesh with the gear 21. The end of the gear 21 is connected to a rotating rod 22 that penetrates into the interior of the sliding plate 19. A worm 23 is fixed to the outside of the rotating rod 22. A worm wheel 24 that meshes with the worm 23 is rotatably connected inside the sliding plate 19. A rotating plate 20 is fixed to the bottom of the worm wheel 24. A screen printing plate 4 is provided at the bottom of the interior of the cavity 15. In this embodiment, the rotary motor 9 drives the screw 10 to rotate. The screw 10 and the slider 11 cooperate with each other, and the sliding plate 19 and the cavity 15 cooperate with each other to limit the movement of the slider 11. At this time, the rotary motor 9 drives the sliding plate 19 to reciprocate. When the sliding plate 19 moves, the gear 21 and the tooth groove 13 cooperate with each other. At this time, the gear 21 rotates, the gear 21 drives the rotating rod 22 to rotate, the rotating rod 22 drives the worm 23 to rotate, the worm 23 drives the worm wheel 24 to rotate, and the worm wheel 24 drives the rotating plate 20 to rotate. The rotating plate 20 scrapes the ink evenly, which can improve the effect of ink coating on the screen printing plate. Example 2 Please refer to Figure 4 and Figure 5As shown, the rotating plate 20 has a cross-shaped cross section. There are three sets of rotating plates 20. The ends of the three sets of rotating plates 20 are all arc-shaped and the ends of the three sets of rotating plates 20 are attached to each other. The bottom of the rotating plate 20 is tightly attached to the screen printing plate 4. The front and rear surfaces of the sliding plate 19 are both fixed with a surrounding plate 12. The top of the sliding plate 19 is fixed with a slider 11. The screw 10 is rotatably connected to the slider 11 through a thread. In this embodiment, by setting the cross-section of the rotating plate 20 to a cross shape, the ink located on the top of the screen printing plate 4 can be dispersed and distributed. At the same time, the screen printing plate 4 and the rotating plate 20 are in close contact to avoid gaps, which would result in lighter local printing colors. Meanwhile, the surrounding plate 12 prevents ink from splashing into the air when dispersing ink. At the same time, the screw 10 and the slider 11 cooperate with each other to complete the screw movement, which in turn drives the sliding plate 19 to move left and right to achieve screen printing. Example 3 Please refer to Figure 4 As shown, the bottom ends of the inner walls on both sides of the cavity 15 are provided with limiting grooves 17. The limiting grooves 17 are fixed with limiting posts 18. The limiting posts 18 are hollow structures. The outer side of the limiting posts 18 is provided with a discharge port 16. The screen printing plate 4 is slidably connected to the limiting posts 18. The top of the screen printing plate 4 is provided with a through hole 14 that communicates with the discharge port 16.

In this embodiment, the screen printing plate 4 and the limiting post 18 are designed to cooperate with each other, and bolts are used to facilitate the replacement of the screen printing plate 4. One end of the hollow limiting post 18 is connected to the ink tube. Under the action of the injection pump, the ink tube injects ink into the interior of the limiting post 18, and then enters the interior of the through hole 14 through the outlet 16. This allows the ink to be positioned above the screen printing plate 4, thus completing the automatic ink filling function. Example 4 Please refer to Figure 1 and 2 As shown, a conveying mechanism 2 is provided at the top of the workbench 1 for conveying cardboard. The conveying mechanism 2 includes a servo motor located on the rear surface of the workbench 1. The output end of the servo motor is connected to an active roller that penetrates into the interior of the workbench 1. A driven roller is rotatably connected to the other end of the workbench 1. A conveyor belt is wound around the outside of the active roller and the driven roller. A pad is fixed between the active roller and the driven roller. A dryer 6 is installed on one side of the top of the workbench 1. In this embodiment, a servo motor drives the active roller to rotate, and the active roller drives the driven roller to rotate under the action of the conveyor belt. The carton to be screen printed is placed above the conveyor belt, and with the help of the pad, screen printing can be completed. The screen-printed carton enters the bottom of the dryer to dry the screen-printed carton, avoiding the phenomenon of ink dispersion when touched, and improving the quality of the product. The working principle and usage process of this device are as follows: First, place the carton to be printed above the conveyor belt. Then, select a suitable screen printing plate 4. The screen printing plate 4 needs to be custom-made, and the internal pattern information is determined according to customer requirements. Next, insert the screen printing plate 4 into the limiting groove 17 and use the fastening bolts 5 to complete the installation and fixation of the screen printing plate 4. Then, under the action of the injection pump, the ink is injected into the limiting post 18, and then enters the through hole 14 through the discharge port 16. This ensures that the ink is located above the screen printing plate 4, completing the automatic ink filling function. Start the servo motor, and the conveying mechanism 2 transports the carton to be printed to directly below the screen printing plate 4. Start the hydraulic rod 8 to drive the screen printing box 3 to move first, so that the screen printing plate 4 squeezes the carton. Start the... The rotary motor 9 drives the screw 10 to rotate. The screw 10 and the slider 11 cooperate with each other, and the sliding plate 19 and the cavity 15 cooperate with each other to limit the movement of the slider 11. At this time, the rotary motor 9 drives the sliding plate 19 to move back and forth. When the sliding plate 19 moves, the gear 21 and the tooth groove 13 cooperate with each other. At this time, the gear 21 rotates, the gear 21 drives the rotating rod 22 to rotate, the rotating rod 22 drives the worm 23 to rotate, the worm 23 drives the worm wheel 24 to rotate, and the worm wheel 24 drives the rotating plate 20 to rotate. The rotating plate 20 evenly scrapes the ink, which can improve the ink coating effect on the screen printing plate. The screen-printed carton is then transported to the bottom of the dryer 6 for drying under the action of the conveyor mechanism 2.
