Abstract

The invention discloses a printing-ink-circulation type ink fountain device of a high-speed printing press. The printing-ink-circulation type ink fountain device comprises a printing ink roller (1). An ink fountain (2) is connected to one side of the printing ink roller (1). The ink fountain (2) is internally provided with an ink scraping blade (3). An ink inlet pipe (4) and a guide groove (5) are arranged above and below the ink scrapping blade (3) respectively. A water pump (6) is connected to one end of the ink inlet pipe (4). An ink storage box (8) is connected to the water pump (6) through a guide pipe (7). The guide groove (5) is internally provided with a linkage rod (9). A plurality of adjusting bolts (10) are connected to the linkage rob (9), and adjusting bolts (11) are further connected to the two ends of the linkage rod (9). The upper end of the ink fountain (2) is provided with an overflow pipe (12), and the overflow pipe (12) is connected with the guide pipe (7). By means of the printing-ink-circulation type ink fountain device, the ink adding frequency can be lowered, and the printing speed is increased; and the printing-ink-circulation type ink fountain device further has the beneficial effects of preventing color difference, being high in adjusting efficiency, high in adjusting accuracy and good in adjusting structure stability and preventing skinning.

Description

technical field [0001] The invention relates to an ink fountain device of a printing machine, in particular to an ink circulation type ink fountain device of a high-speed printing machine. Background technique [0002] In the existing ink fountain device of the printing machine, the ink is generally stored between the ink fountain and the ink roller, the ink is stained with ink by the rotation of the ink roller, and then the ink on the ink roller is scraped by a doctor blade. However, as the printing progresses, the ink in the ink fountain will become less and less. Especially in some high-speed printing machines, the ink consumption is faster, and frequent shutdowns are required to add ink. The frequency of ink addition is higher, and the printing efficiency is lower. In order to improve the printing efficiency of high-speed printing machines, larger ink fountains are generally used on high-speed printing machines to increase the ink storage capacity and reduce the frequenc...
