Flexographic printing system with pivoting ink pan

摘要

A flexographic printing system including an ink pan configured to pivot around a pivot element having a pivot axis. A first bracket affixed to the ink pan is configured to rest on the pivot element, and a second bracket is affixed to the ink pan in an adjustable position and is configured to constrain motion of the ink pan to a pivoting motion around the pivot axis. A fountain roller is mounted on the ink pan and is at least partially immersed in the ink in the ink pan for transferring the ink to an anilox roller having a patterned surface for transferring a controlled amount of ink from the ink pan to the flexographic printing plate. A height adjustment mechanism is provided for adjusting a height of a distal portion of the ink pan to control the extent of contact between the fountain roller and the anilox roller.

主权项

1. A flexographic printing system, comprising:
a plate cylinder on which is mounted a flexographic printing plate for printing on a substrate; an ink pan containing an ink; a pivot element having a pivot axis about which the ink pan is configured to pivot, wherein the pivot element is disposed proximate to a first end of the ink pan; a first bracket that is affixed to the ink pan and is configured to rest on the pivot element for supporting at least a portion of the weight of the ink pan; a second bracket configured to be affixed to the ink pan in an adjustable position, the second bracket being configured to constrain motion of the ink pan to a pivoting motion around the pivot axis, wherein the position of the second bracket is adjustable such that it can slide laterally toward or away from the pivot element; a height adjustment mechanism for adjusting a height of a portion of the ink pan that is distal to the first end; an anilox roller having a patterned surface for transferring a controlled amount of ink from the ink pan to the flexographic printing plate; and a fountain roller that is mounted on the ink pan and is at least partially immersed in the ink in the ink pan for transferring the ink to the anilox roller.
