When a single feeding mechanism 6 fails, the other feeding mechanisms 6 continue to supply ink, ensuring continuous ink supply. The addition of the return material mechanism 5 can form a circulating ink path, allowing the ink to flow continuously and preventing pigment sedimentation. Furthermore, the self-locking motor 9 is activated to drive the output drive shaft 10 to rotate.

The opening and closing plate 23 is installed inside the return material pipe 7, and the opening and closing plate 12 is installed inside the feeding pipe 8. The opening and closing plate 12 and the opening and closing plate 23 are arranged vertically, so that when the return material increases, the feeding material decreases, thereby controlling the amount of ink inside the secondary ink cartridge 2 and avoiding unstable ink supply even under high load continuous operation.

[0042] Reference Figure 4 The stirring assembly 14 includes a stirring motor 1401, which is installed on the outer wall of the ink tank 4. A stirring rod 1402 is fixedly provided at the output end of the stirring motor 1401, and the stirring rod 1402 rotates inside the ink tank 4.

[0043] Specifically, a stirring assembly 14 is installed inside the ink tank 4 to continue stirring the ink inside the ink tank 4. The ink tank 4 is used to store ink. The top of the stirring rod 1402 passes through the ink tank 4 and is connected to the output end of the stirring motor 1401. When the stirring motor 1401 is started, it drives the stirring rod 1402 at the output end to rotate.

The input end of the ink pump 2 601 is located inside the ink tank 4. The output end of the ink pump 2 601 is fixedly connected to a connecting pipe 2 602. The outer wall of the connecting pipe 2 602 is fixedly connected to the outer wall of the feeding pipe 8.

[0047] Specifically, ink pump 2 601 is located on the lower side. Ink pump 2 601 draws ink from inside ink tank 4, then delivers it to feed pipe 8 through connecting pipe 2 602, and finally enters the interior of secondary ink cartridge 2.

[0048] Reference Figure 3 The transmission mechanism 11 includes a bevel gear 1101, which is fixedly connected to the outer wall of the transmission shaft 10. The tooth end of the bevel gear 1101 is meshed with a bevel gear 1102. The outer wall of the bevel gear 1102 is rotatably connected to the inside of the return pipe 7 and the feed pipe 8. The lower surface of the bevel gear 1102 is fixedly connected to the outer wall of the opening and closing plate 12 and the opening and closing plate 13.

[0049] Specifically, the outer wall of the drive shaft 10 is provided with multiple sets of bevel gears 1101, which correspond to the positions of the opening and closing plates 12 and 13 respectively. The rotation of the drive shaft 10 drives the bevel gears 1101 to rotate, and the bevel gears 1101 drive the bevel gears 1102 to rotate. The return pipe 7 and the feed pipe 8 support the rotation of the bevel gears 1102, and the bevel gears 1102 drive the opening and closing plates 12 and 13 to rotate.

[0050] Reference Figure 5 The secondary ink cartridge 2 is equipped with a cleaning motor 15. A lead screw 16 is fixedly installed at the output end of the cleaning motor 15. A slider 17 is threadedly connected to the outer wall of the lead screw 16. A support rod 18 is fixedly connected to the outer wall of the slider 17. A protective box 19 is slidably connected to the outer wall of the support rod 18. The outer wall of the protective box 19 is fixedly connected to the interior of the secondary ink cartridge 2. A first cleaning brush 20 is rotatably connected to the outer wall of the support rod 18. A connecting rod 21 is fixedly connected to the lower surface of the slider 17. A collar 22 is fixedly connected to the outer wall of the connecting rod 21. A second cleaning brush 23 is rotatably connected inside the collar 22.

[0051] Specifically, during cleaning, the cleaning motor 15 is started, which drives the lead screw 16 at the output end to rotate. The lead screw 16 pushes the slider 17 and the support rod 18 to slide. The support rod 18 slides inside the protective box 19. The support rod 18 drives the vertically arranged cleaning brush 20 to slide. The cleaning brush 20 slides against the inner wall of the secondary ink cartridge 2. The slider 17 drives the collar 22 to slide through the connecting rod 21, and the cleaning brush 23 slides. The cleaning brush 23 is arranged horizontally and slides against the inner bottom wall of the secondary ink cartridge 2. Cleaning can be achieved by adding cleaning fluid to the inner wall of the secondary ink cartridge 2.

[0052] Working principle: When using this device, the ink tank 4 is filled with the required amount of ink before the equipment is turned on. To prevent the ink from separating due to prolonged stillness in the ink tank 4, the stirring motor 1401 is started, which drives the stirring rod 1402 to rotate and continuously stir the ink in the ink tank 4 to ensure that the ink is uniform. After the equipment is started, multiple feeding mechanisms 6 work together. The ink pump 601 draws ink from inside the ink tank 4 and delivers it to the feeding pipe 8 through the connecting pipe 602. The ink flows into the secondary ink cartridge 2 along the feeding pipe 8, thus feeding the secondary ink cartridge 2.

[0053] As ink continuously enters the secondary ink cartridge 2, the return material mechanism 5 starts simultaneously, forming a circulating ink path. Ink pump 501 is turned on, drawing ink from the secondary ink cartridge 2 through the return material pipe 7, and then conveying it back to the ink tank 4 through the connecting pipe 502, so that the ink circulates between the ink tank 4 and the secondary ink cartridge 2, effectively preventing pigment sedimentation. During the circulation process, in order to accurately control the amount of ink inside the secondary ink cartridge 2 and avoid unstable ink supply during high-load continuous operation, the self-locking motor 9 starts, driving the transmission shaft 10 to rotate. The bevel gear 1101 on the transmission shaft 10 rotates, which in turn drives the bevel gear 1102 to rotate. Finally, the opening and closing plates 12 and 13 rotate. By adjusting the opening and closing degree of the opening and closing plates 12 and 13, the amount of ink in the secondary ink cartridge 2 is accurately controlled when the return material increases and the feed material decreases.

[0054] Once the ink in the secondary ink cartridge 2 reaches the appropriate amount, under the control of the solenoid valve 3, the ink flows out of the secondary ink cartridge 2 and into the ink fountain or printing press to meet the ink demand of the printing equipment. If a set of feeding mechanisms 6 is damaged during the ink supply process, the other feeding mechanisms 6 can still continue to supply ink stably, ensuring the continuity of ink supply and ensuring that the printing operation is uninterrupted.

[0055] When the printing task is completed or the equipment needs maintenance, the secondary ink cartridge 2 can be cleaned. Start the cleaning motor 15, which drives the lead screw 16 to rotate. The lead screw 16 pushes the slider 17 and the support rod 18 to slide inside the protective box 19. The support rod 18 drives the vertically arranged cleaning brush 20 to slide against the inner wall of the secondary ink cartridge 2 to clean the inner wall. At the same time, the slider 17 drives the collar 22 and the horizontally arranged cleaning brush 23 to slide through the connecting rod 21. The cleaning brush 23 slides against the inner bottom wall of the secondary ink cartridge 2 to clean the inner bottom wall.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
