Problems solved by technology
The temperature of printing ink will change greatly with the change of room temperature. If the temperature of the ink is too low, the viscosity will increase, making it difficult to control the printed pattern, broken line and hue. Bubbles are generated, so that air is easily mixed into the ink, and the wetting of the plate cylinder is deteriorated, and whitening and uneven shades appear
With the progress of the production process, the impurities in the ink will continue to precipitate in the ink chamber, causing problems such as blockage and knife line in the product. In order to avoid the poor printing quality caused by the precipitation and adhesion of the ink, The printing machine must keep the ink in the ink chamber with good fluidity during the working process
[0003] During the printing process, the existing technology cannot achieve automatic heating and cooling, real-time monitoring of ink temperature and regular detection of ink quality

The invention discloses a high-quality ink supply device for a printing press. The high-quality ink supply device comprises an ink cavity, an ink barrel, a conveying system, a backflow system, an inkdetection system and a temperature control system. An ink supply branch formed between the conveying system and the ink cavity is arranged on one side of the ink barrel; a returning branch formed between the backflow system and the ink cavity is arranged on the other side of the ink barrel; the temperature control system is installed in the ink barrel; and the ink detection system is connected with an ink sampling opening reserved in the ink barrel through an ink tube V. The ink tube V is provided with an electromagnetic valve III, and the ink detection system collects ink in the ink barrel inreal time through opening and closing of the electromagnetic valve III, so that he PH value and viscosity of the ink are measured. The high-quality ink supply device for the printing press can achieve the automatic heating and cooling function, monitors the temperature of the ink in real time, and detects the quality of the ink periodically.
Description
technical field [0001] The invention relates to an ink supply control system of a printing machine, in particular to a high-quality ink supply device for a printing machine and a working method thereof. Background technique [0002] Ink is one of the important consumables in the printing process, and it is also one of the main components of the printing cost of printing companies. The quality of ink performance directly determines the printing efficiency and printing quality of printing enterprises. The temperature of printing ink will change greatly with the change of room temperature. If the temperature of the ink is too low, the viscosity will increase, making it difficult to control the printed pattern, broken line and hue. Bubbles are generated, so that air is easily mixed into the ink, and the wetting of the plate cylinder is deteriorated, and whitening and uneven shades appear. With the progress of the production process, the impurities in the ink will continue to p...
