Description

technical field [0001] The invention relates to an ink fountain device of a printing machine, in particular to an ink fountain device of a printing machine which is easy to adjust. Background technique [0002] In the existing printing machine, the ink roller is generally used to dip ink from the ink fountain in the form of rolling, and then the ink on the ink roller is scraped by the doctor blade, which not only can make the ink on the ink roller uniform, but also can By adjusting the distance between the doctor blade and the ink roller, the thickness of the ink on the ink roller can be adjusted, which is used for printing products with different ink consumption. The ink fountain device of the existing printing machine generally adjusts the distance between the doctor blade and the ink roller by setting several adjusting screws; however, when the ink consumption of the printed matter changes, it is necessary to adjust all the adjusting screws to change the ink consumption. ...

AI Technical Summary

Problems solved by technology

The ink fountain device of the existing printing machine generally adjusts the distance between the doctor blade and the ink roller by setting several adjusting screws; however, when the ink consumption of the printed matter changes, it is necessary to adjust all the adjusting screws to change the ink consumption. Not only is it inconvenient to adjust, but the adjustment efficiency is low, and the adjustment errors between the various adjustment screws are easy to appear, resulting in low adjustment accuracy and unsatisfactory printing quality.

Therefore, the existing printing ink fountain device has the problems of inconvenient adjustment, low adjustment efficiency, low adjustment accuracy and unsatisfactory printing quality.
