[0025] like Figure 1 As shown, the ink tank box 1 includes an upper ink tank 4 and a lower ink tank 5 , and the upper ink tank 4 is located at the top of the lower ink tank 5 .

[0026] like Figures 2 to 3 As shown, the stirring part includes: a first stirring component, installed in the lower ink tank 5, for stirring the ink in the lower ink tank 5; a second stirring component, installed in the upper ink tank 4, for separating the ink in the upper ink tank 4 from the ink in the lower ink tank 5, and is configured to form a closed space in the lower ink tank 5 when the second stirring component is not moving; a transmission belt 6, located on one side of the ink tank box 1, and with both ends connected to the first stirring component and the second stirring component respectively, and is configured to rotate the second stirring component through the transmission belt 6 when the first stirring component rotates.

[0027] like Figures 2 to 3 As shown, the first stirring assembly includes: a first stirring rod 7, which is installed in the lower ink trough 5 and is rotatably connected to the inner wall of the lower ink trough 5; a plurality of groups of first stirring blades 8, which are evenly installed on the first stirring rod 7; a first rotating shaft 9, which is located on the lower ink trough 5 and is arranged to pass through the side wall of the lower ink trough 5. The first rotating shaft 9 is connected to the output end of the driving part 3 so that the driving part 3 drives the first rotating shaft 9 to rotate.

[0028] like Figure 2 As shown, the second stirring assembly includes: a second stirring rod 10, which is installed in the upper ink tank 4 and is rotatably connected to the inner wall of the upper ink tank 4; several groups of second stirring blades 11 are evenly installed on the second stirring rod 10, and are arranged so that when the two groups of second stirring blades 11 on the second stirring rod 10 are horizontal, the two groups of second stirring blades 11 are in contact with the side wall of the upper ink tank 4; a second rotating shaft 12 is located on the upper ink tank 4 and is arranged to pass through the side wall of the upper ink tank 4. The second rotating shaft 12 rotates after being transmitted by the transmission belt 6.

[0029] Example 2: Figure 3As shown, it also includes: a first liquid level sensor 13, located on the side wall of the lower ink tank 5; a second liquid level sensor 14, located on the side wall of the lower ink tank 5; the first liquid level sensor 13 is installed above the second liquid level sensor 14, and the first liquid level sensor 13 and the second liquid level sensor 14 are both used to detect the amount of ink in the lower ink tank 5.

[0030] like Figure 3 As shown, it also includes: an ink outlet 15, which is opened on the lower ink tank 5 and connected to the ink pump 2 through a pipeline to draw the ink in the lower ink tank 5 into the ink pump 2.

[0031] like Figure 1 As shown, it also includes: an inkjet cartridge 16, which is located on one side of the ink pump 2 and is configured to spray the ink onto the printed matter through the inkjet cartridge 16 after the ink pump 2 draws ink from the ink tank box 1.

[0034] The technical solution provided by the present invention is that in the inking device of the high-speed printing press, ink enters the upper ink tank 4 through the ink inlet 17 and stays on the second stirring assembly. The printing press first consumes the ink in the lower ink tank 5. When the second liquid level sensor 14 detects that the ink level in the lower ink tank 5 is lower than a preset value, a reminder is issued, and the driving part 3 is controlled manually or through a control system to drive the first rotating shaft 9 to rotate, driving the transmission belt 6, and the transmission belt 6 drives the second rotating shaft 12 to rotate, thereby releasing the ink in the upper ink tank 4 into the lower ink tank 5. When the ink height exceeds the first liquid level sensor 13, the first liquid level sensor 13 detects that the ink level in the lower ink tank 5 is higher than a preset value, and the driving part 3 is controlled manually or through the control system to stop driving; in addition, when the ink pump 2 cannot extract ink, the staff observes whether the ink in the lower ink tank 5 is condensed through the observation port 18. Since the ink cannot be discharged due to condensation, the driving part 3 is controlled manually or through the control system to make the first stirring assembly stir the ink in the lower ink tank 5 so that the ink no longer condenses.
