Description
Technical Field
[0001] The utility model relates to the technical field of printing ink supply, in particular to an ink supply device for a flexographic printing machine. Background Art
[0002] Flexographic printing presses use fluid ink with high fluidity. The ink is transferred to the image and text part of the printing plate by the ink fountain roller and the anilox roller to make it inked. Then the pressure roller applies printing pressure to transfer the ink on the printing plate to the substrate. Finally, the printing process is completed through the drying surface. The inking device of the flexographic printing press is generally composed of an ink fountain and an ink fountain roller.
[0003] The current ink supply device has a single structure and only has the function of temporarily storing ink. The amount of ink supplied cannot be controlled. Moreover, when the ink is not used for a long time, the water evaporates easily and forms lumps, so that the ink fountain roller cannot remove the ink well. Utility Model Content

[0006] Preferably, the ink supply structure includes a threaded rod, the threaded rod is rotatably mounted on the bracket, and one end of the threaded rod is connected to the second motor via an output shaft.
[0007] Preferably, one side of the threaded rod is connected to a movable rod via a thread, and one end of the movable rod is fixedly connected to a limited ink plate.
[0008] Preferably, the ink limiting plate is movably mounted on the ink supply structure.
[0009] Preferably, an ink cap is rotatably mounted on the ink supply structure.
[0010] Preferably, one end of the second motor is fixedly connected to the bracket.
[0011] Compared with the prior art, the beneficial effects achieved by the utility model are:
[0012] First, the utility model can control the supply amount of ink by setting up an ink supply structure and an ink transfer groove. The second motor drives the threaded rod to rotate to drive the movable rod to rise and fall. The lifting of the movable rod drives the ink limiting plate to rise and fall. The ink limiting plate is tightly fitted with the inner wall of the ink supply structure to limit whether the ink can enter the ink transfer groove through the ink supply tube. By controlling the supply amount of ink, the waste caused by excessive addition of ink and unused ink can be reduced.
[0013] Second, the utility model can convert agglomerated ink into liquid again by setting up a first motor and an ink transfer groove. When the ink in the ink transfer groove dries and agglomerates, the first motor drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the grinding stone to rotate and grind the agglomerated ink. At the same time, ink is supplied through the ink supply structure to reliquefy the agglomerated ink, thereby improving the utilization efficiency of the ink and reducing the printing cost.
