Description
Technical field
It the utility model is related to printing machinery, and in particular to a kind of doctor blade device of intaglio printing press.
Background technology
Intaglio printing press is the machine printed using intaglio plate.During printing, first make the space of a whole page inking of plate cylinder, then by scraping
Knife system scrapes the ink of blank parts on the space of a whole page, leaves the ink of areas（Leave the oil of printing plate negative area
Ink）, then by plate cylinder by printing ink transfer to paper, most the paper printed is heaped or rewinding through delivery device afterwards
It is good.Wherein, doctor blade device is mainly used in being that unwanted ink is had into figure to allow from scraped clean on the space of a whole page of plate cylinder
The ink of literary part can be clearly transferred to by printing paper.
A kind of doctor blade device of existing intaglio printing press, including frame, alternating translational seat, support frame, cylinder, doctor blade holder and scrape
Knife, frame are provided with a wallboard placed vertically, and wallboard is provided with a through hole；Alternating translational seat is on front side of wallboard, in frame
Provided with the vibration mechanism that can drive alternating translational seat or so vibration；Support frame has upper horizontal segment, vertical section and lower horizontal segment,
Upper horizontal segment rear end is connected with vertical section upper end, and lower horizontal segment front end is connected with vertical section lower end, and upper horizontal segment is in described logical
Kong Zhong, upper horizontal segment front end are connected with alternating translational seat, and vertical section and lower horizontal segment are on rear side of wallboard, support frame it is vertical
There is gap between section and the trailing flank of wallboard；Doctor blade holder is be hinged at the top of alternating translational seat, before scraper is arranged on doctor blade holder
Side is along upper；The cylinder body of cylinder and the lower horizontal segment of support frame are hinged, the piston rod of cylinder upward and with the back side edge of doctor blade holder
Edge is be hinged.During work, the piston rod of cylinder stretches out upwards, drives scraper scraper is rolled with printing plate to lower swing by doctor blade holder
The space of a whole page contact of cylinder；Subsequent plate cylinder operating, at the same vibration mechanism driving alternating translational seat, support frame, cylinder, doctor blade holder and
Scraper left and right vibration together, scraper is by unwanted ink from scraped clean on the space of a whole page of plate cylinder.But in this scraper
In device, due to having gap between the vertical section of support frame and the trailing flank of wallboard, the length of the vertical section of support frame is longer,
Therefore in printing, support frame trembles before and after easily occurring, and causes scraper to be shaken, so as to cause bracing wire or scumming etc. to print
