Introduction to calender
Calender is used to improve the gloss of the paper surface of the equipment, a calender glazing process. After coating the surface of the printed matter, when the glazing layer is dry, if the smoothness and gloss of the glazing coating need to be improved again, it can be pressed by the calender. The glossiness of general glazing is 65-85%, after pressing can reach 90-95% above glossiness.
Calender is mainly composed of print conveying mechanism, mechanical transmission, electrical control system components, such as, respectively, including print conveying machine, manual high pressure oil pump, hot pressing roller, pressure roller, drive motor speed regulation and pressure light steel belt, cooling tank, observation door, cooling water tank, ventilation and circulation system, transmission roller, print collection.
The working mode of the calender is usually continuous rolling. The printed matter is transported from the feeding table to the pressure belt between the hot press roll and the pressure roll. Under the action of temperature and pressure, the coating is pressed on the surface of the pressure belt. The calendered upper layer gradually cools and forms a bright surface layer. The calender band is a stainless steel ring steel band with special treatment. The inner part of the hot press roller is equipped with several sets of far-infrared heating sources to provide the heat required in the light pressing. The pressure of the pressure of the pressure roller is mostly using the electro-hydraulic pressure regulating system, which can accurately meet the pressure requirement in the pressure light. The pressure and light speed can be controlled by speed control drive motor or slip motor.
