Developing solution constant-proportion dilution equipment for platemaking

Abstract

The invention relates to the technical field of platemaking related equipment, and discloses platemaking developing solution fixed-proportion dilution equipment which comprises a stock solution container, a first feeding pipe is arranged on the surface of the stock solution container, a first photoresistor is arranged in the stock solution container, a dilution container is arranged on the side face of the stock solution container, and a second photoresistor is arranged in the dilution container. According to the developing solution constant-proportion diluting equipment for plate making, through cooperative use of the first photoresistor, the first power source and the variable-current regulator and cooperative use of the first electromagnet and the rotating rod, the developing solution constant-proportion diluting equipment for plate making has the beneficial effects that the developing solution constant-proportion diluting equipment for plate making is simple in structure, convenient to use and high in practicability. The photoresistor II and the power supply II are matched for use, and the electromagnet II and the rotating rod are matched for use, so that the developing stock solution and the diluted solution can be taken out in a fixed proportion and are diluted in a fixed proportion, the concentration accuracy of the developing solution is high, the diluting effect of thedeveloping solution is good, and the developing quality is improved.

Description

technical field [0001] The invention relates to the technical field of plate-making-related equipment, in particular to a proportional dilution device for a developer for plate-making. Background technique [0002] Plate making is a general term for copying originals into printing plates. In plate making, there are the most factors affecting the quality of printing plates, mainly including developer concentration, developing temperature and developing time, as well as the circulation and agitation of developing solution, and the degree of fatigue and decay of developing solution. The concentration of the developer solution, when the concentration of the developer solution is too high, the development operation is often difficult to control due to the too fast development speed, and it is easy to cause dot shrinkage, damage, loss of bright-tone small dots and thinning of the coating, resulting in a decline in printing durability At the same time, the oxide film and sealing la...
