Skin-forming-preventing ink fountain device for printing press

Abstract

The invention discloses a skin-forming-preventing ink fountain device for a printing press. The skin-forming-preventing 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 scrapping blade (3). A heating and stirring device (4) is arranged above the ink scrapping blade (3). A guide groove (5) is arranged below the ink scraping blade (3). The guide groove (5) is internally provided with a linkage rod (6). A plurality of evenly-distributed adjusting screws (7) are connected to the linkage rob (6) through threaded holes. One end of each adjusting screw (7) is connected with the bottom end of the ink scraping blade (3) in a contact manner. Adjusting bolts (8) are further connected to the two ends of the linkage rob (6). The adjusting bolts (8) are connected with the ink fountain (2) through threaded holes. The ink fountain device has the beneficial effects of preventing skin forming and being high in adjusting efficiency, the adjusting accuracy, the printing quality and the adjusting structural stability can be further improved, and the application range is enlarged.

Description

technical field [0001] The invention relates to an ink fountain device of a printing machine, in particular to an anti-skinning ink fountain device of a 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, after a long time of use, the ink in the ink fountain is prone to skinning, resulting in increased ink viscosity and reduced printing quality; especially when the temperature is low, the skinning situation is more serious and the printing quality is lower. Moreover, the ink fountain device of the existing printing press generally adjusts the distance between the doctor blade and the ink roller by setting several adjusting screws; however, when the ink consumption of the printed matter changes, it is necessary to...

AI Technical Summary

Problems solved by technology

However, after a long time of use, the ink in the ink fountain is prone to skinning, resulting in increased ink viscosity and reduced printing quality; especially when the temperature is low, the skinning situation is more serious and the printing quality is lower

Moreover, the ink fountain device of the existing printing press generally adjusts the distance between the doctor blade and the ink roller by setting several adjusting screws; however, when the ink consumption of the printed matter changes, it is necessary to adjust all the adjusting screws to change Ink consumption, not only the adjustment efficiency is low, but also the adjustment errors between the adjustment screws are more likely to occur, resulting in lower adjustment accuracy and unsatisfactory printing quality

Therefore, the existing printing ink fountain device has the problems of easy skinning, low adjustment efficiency, low adjustment accuracy and unsatisfactory printing quality
