Offset press printing ink working temperature controller

Abstract

The invention discloses an ink working temperature control device for an offset printing machine which comprises an inking roller medial axis body and a heat conducting oil heating / cooling device. A heat conducting oil cavity is arranged at the middle part of a working axis of an inking roller medial axis, a passage is arranged at the middle part of a rotary axis at both ends of the inking roller medial axis to be interpenetrated with the heat conducting oil cavity, the other end of the passage is respectively communicated with a heat conducting oil input pipe and a heat conducting oil output pipe through rotary sealing pieces, the heat conducting oil input pipe is connected with the output end of the heat conducting oil heating / cooling device, the heat conducting oil output pipe is connected with the input end of the heat conducting oil heating / cooling device, and the heat conducting oil input pipe or the heat conducting oil output pipe is also provided with a heat conducting oil pump. The invention can conveniently realize heating or cooling on an inking roller and ink, controls ink working temperature around 25 DEG C, and well solves influence of temperature to the printing quality; has balanced heating / cooling, and has obvious effect on enhancing the printing quality, in particular to quality of high precision printing. Meanwhile, the technical scheme has the advantages of simpleness and easy practice.

Description

technical field [0001] The invention relates to an ink feeding mechanism of an offset printing machine, in particular to an ink working temperature control device of an offset printing machine. Background technique [0002] The inking system of an offset printing machine is composed of a number of ink shifting rollers, ink distribution rollers, inking rollers, ink fountain rollers and ink transfer rollers of various diameters. The central shaft of each ink roller is composed of the working shaft and the rotating shaft at both ends. The working shaft is outsourced to the corresponding working surface, and the rotating shaft at both ends of the central shaft is installed on the frame of the offset printing machine. When the offset printing machine works at a lower temperature, due to the condensation and solidification of the ink, it will have a negative impact on the ink supply, ink distribution, and ink placement, resulting in serious printing quality problems, and even the ...

AI Technical Summary

Problems solved by technology

When the offset printing machine works at a lower temperature, due to the condensation and solidification of the ink, it will have adverse effects on ink supply, ink distribution, and ink placement, resulting in serious printing quality problems, and even failure to start the machine.

When working at a higher temperature, the printing quality will be seriously reduced due to the denaturation of the ink, which will cause great troubles to printing companies, especially high-precision printing.
