The calender is mainly used for single-face and double –face once continuous coating of card, canvas and other woven material, sheeting rubber stock , calendaring thin rubber sheet of inner liner and airtight layer of the radial tire.
1.The rolls are made from alloy chilled cast iron, sturdy and durable.
The roll surface and shaft journal are clamped and grinded on high precise CNC grinder, which enable roller with micron geometric tolerance.
2. For increasing calendaring accuracy, set preloading device, axis cross device and bending resistance device, etc. On rolls in order to eliminate bending caused during working.
3.Single motor drives each calendaring roll, friction ratio of which can be regulated by pulling key so as to meeting different processes. Multi motors drive available by requirement for higher accuracy control.
4.Emergency stop is available for protecting operators and equipment.
5.Electric control adopts imported PLC , guarateeting control on the safe side, easy operation and high automation.
6.Four row cylinder roller bearing of high precise is used to support the calender roll, which possess higher precise of rotation by contrast with self-aligning roller bearing.
7.Pre-loading and cross systems available by customer requirement , which keeps machine stable and the product with high precision thickness control .
8.Encoder of high precision is adopted for detecting motor speed of roll. Speed closed-loop control system keeps roll hard mechanical property while enlarging load.
