Ink fountain device for ink circulation type high-speed printing machine

Abstract

The invention discloses an ink fountain device for an ink circulation type high-speed printing machine, which comprises an ink roller (1), and an ink fountain (2) is connected to one side of the ink roller (1); An ink inlet pipe (4) and a guide groove (5) are arranged above and below the ink blade (3); one end of the ink inlet pipe (4) is connected to a water pump (6), and the water pump (6) is connected to a Ink storage box (8); linkage rod (9) is arranged in the guide groove (5), and several adjustment screws (10) are connected on the linkage rod (9), and the two ends of the linkage rod (9) are also connected with adjustment bolts ( 11); the upper end of the ink fountain (2) is provided with an overflow pipe (12), and the overflow pipe (12) is connected with the conduit (7). The invention can not only reduce the frequency of adding ink and increase the printing speed, but also has the advantages of preventing color difference, high adjustment efficiency, high adjustment precision, good adjustment structure stability and anti-skinning.

Description

Technical field [0001] The invention relates to an ink fountain device of a printing press, in particular to an ink circulation type high-speed printer ink fountain device. Background technique [0002] In the existing ink fountain device of the printing press, the ink is generally stored between the ink fountain and the ink roller, and the ink is stained by the rotation of the ink roller, and then the ink on the ink roller is scraped by a doctor blade. However, with the progress of printing, the ink in the ink fountain will become less and less, especially in some high-speed printing presses, the ink consumption is faster, it is necessary to frequently stop the ink to add ink, the frequency of ink filling is higher, and the printing efficiency is lower. In order to improve the printing efficiency of high-speed printers, larger ink fountains are generally used on high-speed printers to increase ink storage capacity and reduce the frequency of ink addition; however, the thixotropy...

AI Technical Summary

Problems solved by technology

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 it is necessary to stop frequently 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 frequency of ink refilling; however, the thixotropy of the ink is strong, and the ink in the ink fountain is easy to store after a long time Causes the ratio of various colors in the ink to change, which in turn makes the printed matter prone to chromatic aberration

Therefore, the existing ink fountain device of high-speed printing machine has the problems of relatively fast refill frequency, low printing speed and prone to chromatic aberration
