Integrated type centralized fountain solution automatically-proportioning device

Abstract

The invention discloses an integrated type centralized fountain solution automatically-proportioning device which comprises a power switch, a liquid adding switch, an instrument switch, an alarm lamp,a PH instrument, a conductometer, an alarm controller, a liquid proportioning outlet switch, a water valve, a non-return valve, a proportioning pump, a liquid level sensor, a liquid storage barrel, aliquid adding pump, universal wheels, a raw liquid barrel, a water pipe, a water filter, a shell, a pH value sensor, a conductivity sensor and a proportioning liquid detection device, wherein the power switch is positioned at the left side above the front surface of the shell; the liquid adding switch, the instrument switch, the pH instrument and the conductometer are sequentially distributed atthe right side of the power switch; the water pipe is arranged in the relatively-upward position of the middle parts of the left and right sides of the shell and transversely passes through the shell;the water valve, the water filter, the non-return valve, the proportioning pump, the proportioning liquid detection device and the liquid proportioning outlet switch are sequentially distributed on the water pipe from left to right; and the liquid storage barrel is positioned at the right of the inner side of the bottom of the shell. The device disclosed by the invention is simple in structure, convenient to operate, long in service life, high in efficiency, low in cost and capable of effectively improving the printing quality.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to an integrated centralized fountain solution automatic proportioning device. Background technique [0002] Printing fountain solution is an indispensable chemical additive in the printing of color printing machines. It forms a uniform water film on the blank part of the printing plate to resist the infiltration of ink on the graphic and text to the blank part and prevent dirty plates. At present, the printing water is not standard, which affects the quality of printing, and is easily affected by changes in external water quality. The water quality is too hard, and the high concentration of calcium and magnesium ions will cover a layer of white foggy precipitation on the water transfer and ink transfer rollers of the wetting system and ink transfer system after precipitation reaction, which reduces the transfer ability of water transfer and ink transfer, and increases the detachme...

AI Technical Summary

Problems solved by technology

If the water quality is too soft, it will easily cause excessive emulsification of the ink, expansion of dots in the graphics and text, and easy contamination of the fountain solution in the water tank
