Gravure coating constant temperature control system and control method

Abstract

The invention relates to a gravure coating constant temperature control system. The gravure coating constant temperature control system comprises a central controller, a first electromagnetic valve, awater cooling device, a temperature sensor and a temperature display, wherein the input end of the central controller is connected with the output end of the temperature sensor, the central controller is connected with the first electromagnetic valve, the first electromagnetic valve is installed in the water cooling device and controls whether cooling water of the central water cooling system ofa factory passes through the water cooling device, and the central controller is connected with the temperature display. The problem that the quality of the coating changes due to the unstable temperature of the printing coating is well solved. The processing quality of the synthetic leather finishing process is effectively improved. The movable probe type temperature sensor is adopted, and more temperature signals can be collected so as to provide more accurate and real-time temperature condition information. An independent monitoring system is provided for the working state of the whole system, the whole system can be manually closed, and the automatic control system is only partly relied on. The gravure coating constant temperature control system has the beneficial effects that the changing range of the temperature of liquid medicine in the printing process can be controlled rapidly, stably and safely, the stability of the liquid medicine can be improved and the quality of the processing technology can be improved.

Description

technical field [0001] The invention relates to a gravure coating constant temperature control system. Background technique [0002] In the synthetic leather printing and embossing production line, the printing link is the process of printing paint onto synthetic leather through a gravure wheel to change its surface properties. What is used in the present invention is a gravure finishing process, the main process is that the gravure wheel in the finishing tank passes through the paint tank under the drive of the motor, and after being stained with an appropriate amount of paint, it is printed on the synthetic leather to form the desired pattern or special surface properties. [0003] In this processing process, due to the influence of the external environment and equipment, the temperature of the configured paint in the paint tank is constantly changing, so the state of the paint itself is also constantly changing in this process, and the resulting synthetic leather The in...
