| Core principle |
★ Super calender machine is made for paper production grooming equipment. It belongs to soft grooming machine, suitable for offset paper, newspaper, coated paper, capacitor paper, translucent paper, bag paper, culture paper.
★ Super calender machine use muti-group of smooth rollers to calender the paper, when paper goes through the paper roller and steel roller press area, after the paper roller, the deformation zone can reach different rotation speed and sliding friction. Under mechanical pressure and heat power, the paper will become more smooth gloss, dense. flat. gaining more transparency, prevent and reduce power slip. hair slip. Improves quality and appearance.
★ Equipped by tension control system, it detect the smooth, gloss and thickness on line.
★ Adopt axe paper rolling, hydraulic adjustable roller riding technology.
★ Working speed adjust smoothly and precisely. |
| Analysis of key technologies of super calender |
 Zone controllable medium and high |
● Principle: Multi-zone independent hydraulic chamber, realtime adjustment of deflection, compensation for thermal deformation.
● Application: It is suitable for high-basis weight, wide-width,high-speed paper machines, ensuring uniform thickness.
● Advantages: Small banner difference, no need to stop themachine for online fine adjustment, and extended lifespan. |
| Step-by-step transmission system |
● Principle: Independent motor + variable frequency drive, precise control of speed difference and torque.
● Application: Fine-tune the balance between paper gloss, smoothness, and tightness.
● Advantages: Eliminates slipping and scratching, ensures stable surface quality, and provides reasonable load capacity. |
| Balance and rapid roll-off |
● Principle: Constant force support, pressure relief and disengagement at the moment of emergency stop, to protect the equipment.
● Application: Suitable for paper guiding during startup, paper break recovery, and emergency stop in case of malfunction.
● Advantages: Smooth paper guiding, reduced paper breakage losses, and prevention of damage to the roller surface. |
| Composite material encapsulation |
● Principle: High-performance polymer composite gradient structure, precisely matching hardness.
● Application: Used for soft calender work rolls to enhance gloss and smoothness while maintaining bulkiness.
● Advantages: Gentle pressure zone, high temperature wear resistance, low noise, and easy maintenance. |
