Zoning ink box for printer

Abstract

The zoned ink box for printing machine has one ink box body, two side stoppers with front arced slot matching the ink roller, support shafts at two ends and connected to the wall boards of printing machine, one row of fixed blocks embedded parallelly to the upper side and with notch, one row of ink supplying blocks below the fixed blocks with lug inserted into the corresponding notch, cam levers installed onto the ink supplying blocks separately and with rotating shaft connected to the fixed block, and elastic metal sheets covering each of the ink box body, fixed blocks and ink supplying blocks separately. The zoned ink box has separately adjustable ink supply amount for each zone and thus homogeneous ink supply.

Description

technical field [0001] The invention relates to a printing device, in particular to an ink fountain of a printing machine. Background technique [0002] In the traditional printing machine ink fountain, there are left and right stoppers installed on the left and right sides of the ink fountain body. The tail ends of the left and right stoppers are provided with spring plates, and the front ends of the left and right stoppers are provided with arc grooves that cooperate with the ink fountain rollers. The left and right sides of the ink fountain body Both ends are provided with support shafts connected to the wallboard of the printing machine, and the position of the ink fountain on the printing machine is adjusted by its positioning pillars. An elastic ink fountain blade is installed above the ink fountain body, and a row of elastic ink fountain blades is installed on the top of the ink fountain body. The adjustment screw on the upper part controls the ink supply volume of th...

[0002] In the traditional printing machine ink fountain, there are left and right stoppers installed on the left and right sides of the ink fountain body. The tail ends of the left and right stoppers are provided with spring plates, and the front ends of the left and right stoppers are provided with arc grooves that cooperate with the ink fountain rollers. The left and right sides of the ink fountain body Both ends are provided with support shafts connected to the wallboard of the printing machine, and the position of the ink fountain on the printing machine is adjusted by its positioning pillars. An elastic ink fountain blade is installed above the ink fountain body, and a row of elastic ink fountain blades is installed on the top of the ink fountain body. The adjustment screw on the upper part controls the ink supply volume of the ink fountain by adjusting the screw. The disadvantage of the ink fountain of this structure is that due to the elasticity of the elastic ink fountain blade itself, local adjustment of the ink supply volume is likely to cause ink volume in adjacent areas. Changes, resulting in uneven ink supply, and a certain part of the elastic ink fountain blade is likely to be elastically deformed due to the top pressure of the adjustment screw, it is difficult to meet the ink supply requirements of high-end printed matter, and the overall elastic ink fountain blade is thin and flat. The requirements are high, the manufacturing accuracy is difficult to meet the use requirements, and the processing cost is high
