Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment processing, in particular to a water-ink balancing device for a printing press. Background Art

[0002] The water-ink balance device of a printing press is one of the key components to ensure printing quality. It is mainly responsible for adjusting and controlling the ratio of water (wetting fluid) to ink (ink) during the printing process to ensure that the ink can be transferred evenly and clearly on the substrate, while avoiding printing defects such as sticking and smudging. The basic principle of water-ink balance is to use wetting fluid (the main components are water and some additives) to keep the non-image part of the printing plate moist to prevent the ink from adhering to these parts, while the image part can well accept and transfer the ink to paper or other printing materials. The water-ink balance device of a printing press is a complex mechanism involving multiple subsystems. Through precise control and coordination, it ensures high-quality output of printed products.

[0003] However, when the existing printing machine is not used for a long time after the employees stop working for a break, especially in a low temperature environment, the ink on the ink roller may dry, harden and form a crust. This is because the solvent in the ink will gradually evaporate, leaving solid components, and it is inconvenient for subsequent users to enter the interior of the machine for cleaning and maintenance, which reduces the work efficiency of the printing operation. In addition, the existing water-ink balancing device cannot control the thickness of the ink layer on the ink roller and improve the fineness of the printing. Therefore, it is necessary to propose a new type of water-ink balancing device for a printing machine. Utility Model Content
