Stepless Pressure Regulation S-Roll Calender

Main Features Of S-Roll Calendering Machine

• Utilize the stepless pressure regulation S-Roll, achieve the uniform line pressure by adjusting the oil pressure in the two semi-circular chambers.
• The elastic roller sleeve coated on the stepless pressure regulation S-Roller can better recover the deformation of the roller.
• The S-Roller is controlled by hydraulic system.
• The S-Roller is auxiliary driven by oil motor.
• HMI (Whole machine monitoring, Process parameter settings, Seam detection animated display, Hydraulic system pressure display, Fault diagnosis, Alarm information)
• Roller sleeve change is quick and easy, no need to have a large scale demolition the soft roller sleeve made of synthetic material can be exchanged from the side pipe rack of the calender, to minimize the downtime. The sleeve can be selected in calendering process(such as calendering. electro-optical, embossing, soft calendering and silk finishing).

Advantages Of S-Roll Calender Machine

• Muti embossing roll design, the smooth switching of the two patterns can be completed in a few     minutes, making the production more efficient and easy;
• The line width of the entire roll surface can be adjusted step-less, which ensures uniform and smooth line pressure within the width of the fiber cover, thus making a perfect non-woven fabric;
• The roller adopts high-speed circulating supply of heat-conducting oil, and the temperature difference among the roller surface is ±1°C; The maximum temperature can reach 280°C;
• The roll is equipped with a rapid cooling heat exchange system to improve the efficiency of product switching during production;
• The bearing is lubricated by independent cooling unit to effectively extend the service life;
• Provide refrigeration unit for rapid cooling of rolls, fabric cooling rolls, bearing cooling    units,hydraulic systems,etc.,to ensure that all components operate in a more excellent state;
• All operations are focused on the touch screen, which can quickly grasp the machine performance parameters, and can run efficiently through simple settings, greatly reducing the dependence on people;
• New improvements in the roll mechanism, transmission mode, heat transfer efficiency, and intelligent control; Suitable for various production processes such as PP/PE/PET;

• A high-performance spin-bonded non-woven fabric production line step-less pressure regulating S-Roll technology high-speed hot rolling mill, which allows the quantitative range, strength elongation at break, thickness, longitudinal and transverse strength ratio, feel of non-woven products performance, such as breath ability is perfect.
• Human machine interface touch screen operation, machine monitoring、technical parameters setting、hydraulic system control、fault diagnosis、alarm system.

Basic Working Principle Of Calendering Machine

A steel sleeve rotates around a fixed eccentric shaft core. The sealing disc at both ends of the shaft core and the sealing strips installed on both sides of the shaft divide the annular gap pressurized by heated transfer oil and the other side is the oil return cavity. By controlling the pressure in the oil inlet chamber and the pressure difference between the two oil chambers, compensation adjustment of step-less pressure regulating S-Roll is to follow the line pressure setting process, continuous and automatic synchronization. When processing different quantitative products, the line pressure of each point of the roller can keep uniform. In the operation process, the step-less pressure regulating S-roll technology can be used to control the line pressure to the state required by the process.
