Calender, in simple terms, is used to improve the gloss of a paper equipment, is a matte glazing process. Under normal circumstances, after the surface of the printed matter is coated, the gloss layer is dried, and the gloss, smoothness and gloss of the coating need to be improved again. At this time, calender is required. The gloss of the glazing can only reach about 655 to 85%, but the gloss after calender can reach 905 to more than 95%. Composition of 1. calender The calender consists of three parts, namely, the printing conveying mechanism, mechanical transmission and electrical control system. 2. working principle Continuous roller pressing is the most commonly used working mode of calender. Printed matter is transported from the paper conveying table to between the hot pressing roller and the pressing roller. Under a calender belt, under the action of temperature and pressure, the coating will stick on the surface of the calender belt and then be calendered. The coating layer after calendering will gradually cool down, and the stroke has a bright surface layer. The calender belt is a specially treated stainless steel belt. It is worth mentioning that there are many groups of far-infrared heating sources inside the hot roller, which can provide the heat required in the calender process. The pressure of the pressure roller, usually also adopts the electric hydraulic pressure regulating system, they can be very accurate to meet the pressure required in the process of calendering. The calendering speed is also adjustable, and can be adjusted by a speed-regulating drive motor or a slip motor.

2. working principle
Continuous roller pressing is the most commonly used working mode of calender. Printed matter is transported from the paper conveying table to between the hot pressing roller and the pressing roller. Under a calender belt, under the action of temperature and pressure, the coating will stick on the surface of the calender belt and then be calendered.

The pressure of the pressure roller, usually also adopts the electric hydraulic pressure regulating system, they can be very accurate to meet the pressure required in the process of calendering.
The calendering speed is also adjustable, and can be adjusted by a speed-regulating drive motor or a slip motor.
