Description

Technical Field

[0001] The present invention relates to the technical field of printing presses, and more particularly to an ink supply device of a printing press. Background Art

[0002] After the ink has been stored for a period of time, the viscosity of the upper part of the container is low, and the color and concentration are poor; the viscosity of the lower part is high, and the color and concentration are also good. This type of ink is a fluid with low viscosity. Since the pigment is not well dispersed in the binder and the relative density of the pigment or filler is too small, it is easy to precipitate after long-term storage. In order to make the pigment and the binder fully and evenly mixed again, the ink can be re-stirred. When the printing press is in use, the ink needs to be supplied to the printing press so that the printing press can print;

[0003] Prior art CN111959127B is an ink supply device for a printing press, in which the supply assembly and the discharge assembly are arranged to realize automatic ink adding according to the amount of ink in the ink cartridge, thereby ensuring the working efficiency of the printer and reducing the workload of the staff; the arrangement of the locking assembly increases the sealing between the sealing plate and the discharge pipe, and at the same time the locking assembly utilizes the power provided by the discharge assembly to realize automatic locking of the sealing plate, thereby increasing the stability of the discharge assembly; the barrel is located at the center position in the length direction of the machine body, shortening the length of the hose, thereby reducing the influence of the hose on the stability of the print head during movement, thereby ensuring the stability of the printer.

[0004] However, the device still has a shortcoming in that it is not convenient to fully mix the ink in the ink cartridge when using the device, which causes the ink in the ink cartridge to be stratified. When it is supplied for use, it will cause the printed color to be different, resulting in waste of printed materials. In view of this, we propose an ink supply device for a printing press.
