Abstract

The invention discloses an ink key driving device for a printer. The driving device comprises a handspike and a handspike driving device, wherein, the handspike driving device comprises a plane cam and a manual zero adjusting unit or self regulating unit; the end of the handspike is up against the drive surface of the plane cam, and the plane cam is connected with the manual zero adjusting unit and the self regulating unit. The ink key driving device can precisely adjust the gap between an ink key and an ink fountain roller, thereby realizing precise automatic adjustment of the amount of jetted ink, and is completely suitable for being used on printers.

Description

technical field [0001] The invention relates to a driving device for an ink fountain of a printing machine, in particular to an ink key driving mechanism of a printing machine. Background technique [0002] The ink key driving mechanism of the printing machine is an important part to control the ink output of the ink fountain of the printing machine. The driving mechanism determines the ink output accuracy of the ink fountain. The existing adjustment method that directly adjusts the ink key push rod (jack shaft) to adjust the distance between the ink key and the ink fountain roller to control the ink output has the problems of low adjustment accuracy and difficult control. Contents of the invention [0003] The purpose of the invention is to design a printing machine ink key driving mechanism. [0004] The present invention aims to solve the problems of low adjustment accuracy and difficult control of the adjustment accuracy of the existing printing machine ink key drive ...
