Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments.
As shown in fig. 1 to 4, the doctor blade holder for a printing machine according to the present embodiment includes a holder body 1, an upper doctor blade 5 and a lower doctor blade 6 are provided on the holder body 1, the upper doctor blade 5 and the lower doctor blade 6 are in surface contact with an anilox roller 7 of the printing machine, the holder body 1 and the lower doctor blade 6 define an ink containing groove which is open upward, the ink containing groove has ink outlets at two ends in an axial direction of the anilox roller 7, and an opening and closing device capable of opening and closing the ink outlets is provided on the holder body 1. Because the two ends of the ink containing groove formed by the knife rest body 1 and the lower ink scraping knife 6 are provided with the ink outlets, and the opening and closing device capable of opening and closing the ink outlets is arranged, the ink level of the ink containing groove during printing can be improved, the ink quantity in the ink containing groove is ensured to be sufficient, and the phenomena of ink shortage and ink lack are avoided; when cleaning, the cleaning solvent in the ink containing groove can be discharged through the ink outlet, so that ink or residual cleaning solvent in the ink containing groove is avoided, the ink containing groove is easier to clean, the cleaning efficiency can be improved, and the cleaning quality can be improved; the doctor blade rest for the printing machine also has the advantages of simple structure, low cost and easy manufacture.
In this embodiment, the main body 1 has an inclined plane, the lower doctor blade 6 and the inclined plane define a through groove with an upward opening and two through ends, and the two ends of the through groove are used as two ink outlets. The opening and closing device has simple structure, easy manufacture and easy cleaning of the ink containing groove.
In the present embodiment, the opening and closing device includes a valve plate 2 and a driver 4 that drives the valve plate 2 to rotate to open and close the ink outlet. The ink outlet can be conveniently opened and closed.
