Example Embodiment

[0028] The following describes the preferred embodiments of the present invention in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to make a clearer and clearer definition of the protection scope of the present invention;

[0029] Such as Figure 1-2 As shown, the technical solution of the present invention is a gravure printing machine and its ink cooling system including an ink printing mechanism and an ink cooling system;

[0030] The ink printing mechanism includes an ink tank 20, a doctor blade 21, a printing roller 22, and an impression roller 23. The printing roller 22 is arranged above the inside of the ink tank 20, and the impression roller 23 is arranged above the printing roller 22. The scraper 21 is installed above the inside of the ink tank 20 and is in contact with the printing roller 22 for scraping off excess ink on the printing roller ...

Abstract

The invention discloses a gravure printing machine and an ink cooling system thereof. The ink cooling system thereof comprises an ink printing mechanism and an ink cooling system, wherein the printingink printing mechanism comprises an ink groove, a scraper and a printing roller; the printing ink cooling system comprises a machine frame, a cooling tank, a stirring motor, supporting foot frames, supports, a condenser, a control main machine, an ink pumping pump I, an ink pumping pump II and a filtering cylinder; and the filtering cylinder, the cooling tank and the supports are sequentially installed on the machine frame from left to right. According to the machine and the system, a traditional printing technology is upgraded, the overall cooling system is a closed type, harmful gas is notdischarged into the air, the operation process is more environment-friendly, and no pollution is caused to the environment; after the cooling system is used, the problem that the temperature of the existing printing ink is high can be solved, the volatilization speed of a solvent can be reduced, the use amount of the solvent can be reduced, and the quality problems of products such as dry printingand dragging caused by high ink temperature are reduced as well, and green printing is achieved.

Description

technical field [0001] The invention belongs to the field of printing equipment, in particular to a gravure printing machine and an ink cooling system thereof. Background technique [0002] During the printing process, the paper passes through the oven to heat and dry the printed ink. Although the paper is cooled by the cold water roller when it is output from the oven, due to high-speed printing and the friction between the paper guide rollers of the printing equipment, the paper will still have a certain degree of friction. temperature. At the same time, when printing, the doctor blade needs to rub against the printing plate roller to scrape off excess ink, and the friction for a long time will generate a lot of heat in this process. Moreover, when the paper passes between the printing plate roller and the embossing roller running at high speed, the friction between the paper and the printing plate roller will also generate heat. During the printing process, the heat wil...
