Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of printing equipment, in particular to an ink cooling device for a gravure press. BACKGROUND

[0002] The gravure press is a special equipment using gravure printing technology, and its core principle is to store ink in the recessed graphic part of the surface of the gravure cylinder, remove the ink in the blank area by the doctor blade, and then transfer the ink to the surface of the printing material by the impression cylinder to complete the printing. The ink cooling device for the gravure press is a special equipment designed for the problem of temperature rise of ink during printing. In the continuous operation of the gravure press, the temperature of the ink rises due to the recycling and mechanical friction, causing accelerated solvent evaporation and increased viscosity, and further causing problems such as incomplete printing pattern, broken lines and color phase out of control. The core function of the ink cooling device for the gravure press is to maintain the stability of the ink temperature and control the viscosity of the ink, thereby ensuring the stability of the printing quality.

[0003] In the prior art, the ink cooling device for the gravure press generally includes an ink tank, a shell, a liquid cooling assembly and an ink pipe. The ink tank is installed in the shell, the liquid cooling assembly is installed on the outer peripheral wall of the ink tank, and the ink pipe is installed on the upper surface of the shell. When the gravure press needs to perform printing work, the ink in the ink tank is cooled and cooled by the liquid cooling assembly first, and when the temperature is lowered to a suitable printing temperature, the ink is sucked out through the ink pipe and used for printing, thereby realizing the cooling and cooling of the ink, making the ink at a suitable printing temperature, and further improving the printing quality.

[0004] For the related technology in the above, since the liquid cooling assembly is installed on the outer peripheral wall of the ink tank, the liquid cooling assembly can directly cool the ink close to the inner wall of the ink tank, but the ink in the middle position of the ink tank cannot be cooled and cooled in time, thus leading to uneven cooling of the ink and relatively poor cooling effect, and therefore improvement is needed.
