Abstract

The invention belongs to the technical field of printing machines and particularly relates to a cooling device and method for a plate cylinder of a gravure printing machine. The cooling device and method solve the problem that design is not reasonable in the prior art. The cooling device for the plate cylinder of the gravure printing machine comprises an ink groove which is horizontally arranged, and part of the plate roller is partly immersed in printing ink in the ink groove. The ink groove is connected with a printing ink box through a printing ink circulation system, and the printing ink box is located in a cooling water tank which is connected with a cooling water machine through a cooling water circulation system. The water level of cooling water in the cooling water tank is higher than the liquid level of printing ink in the printing ink box. The cooling and method have the beneficial effects that design is reasonable, and the cooling effect is good.

Description

technical field [0001] The invention belongs to the technical field of printing machines, and in particular relates to a cooling device for a plate cylinder of a gravure printing machine and a cooling method thereof. Background technique [0002] In gravure printing, the ink transfer rate is usually between 50% and 80%, and 1 / 4 to 1 / 2 of the ink is always left in the cell. When the residual rate of ink in the cells of the printing plate cylinder increases, the transfer rate of the ink will decrease accordingly, resulting in plate blocking failure, which will result in shallow printing mesh, unclear printing of small characters and patterns, light solid color, serious It will cause broken pens and less paintings. One of the reasons is that the temperature of the plate cylinder is too high and the solvent in the ink evaporates too fast. [0003] For example, Chinese patent literature discloses a gravure printing machine cooling roll device [Application No.: 201120483984.5], ...
