Sl Type S-Roll Hot Calender

Nip Pressure Controllable

Basic Working Principle

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 between the steel sleeve and the shaft core into two halves. The cavity facing the nip is pressurized by heated transfer oil and the other side is the oil return cavity. By controlling thepressure in the oil inlet chamber and the pressure difference between the two oil chambersthe bending deformation of the roller wall can be changed and controlled. The automatic compensation adjustment of stepless 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 stepless pressure regulating S-Roll technology can be used to control the line pressure to the state required by the process.

Advantage

▪ Multi 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 steplessly, which ensures uniform and smooth line pressure within the width of the fiber cover, thus making a perfect nonwoven fabric;
▪ Line pressure between rolls: 0-150N/mm, the maximum line pressure in special working conditions can reach 300N/mm;
▪ The rolle adopts high-speed circulating supply of heat-conducting oil, and the temperature difference among the roler surface is ±1°C;
▪ The maximum temperature can reach 280°C:
▪ The maximum operating speed can reach 800m/min;
▪ The rollis equipped with a rapid cooling heat exchange system to improve the eficiency 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, et., 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 efficientythrough 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 spunbonded non-woven fabric production line stepless pressure regulating S-Roll technology high-speed hot roling mill, which allows the quantitative range, strength, elongation at break, thickness, longitudinal and transverse strength ratio, feel of nonwoven products Performance, such as breath ability is perfect.
▪ The maximum width:6000mm (width can be desianed as client’s requirements)
▪ Human machine interface:touch screan operation、machine monitoring、tachnical parameters setting、 hydralulic system control、fault diagnosis、 alarm system.
