Rubber Inner Liner Extruding and Calendaring Line

Use:

This line mainly consists of ￠200pin cold feed extruder and XY-211300 rubber two-roll calendar ,equipped with all kinds of accessory units to produce two-layer hot-combined inner liner, two-layer or three-layer cold-combined inner liner ,and single-layer thin rubber sheet, which will be supplied to radial tire or bias tire building machine or multi-cutter slitting machine.

Features:

1、The screw is new high-efficiency pin screw ,which can ensure high output of extruder and no remains when discharging .the screw is made of double-metal material ,its surface is hard and wear-resistance by being plate with chrome .the temperature of screw is controlled by one set of TCU.

2、The barrel of extruder is drilled on wall to put thought water for heating or cooling .the liner is made of double-metal material , having high hardness and good wear-resistance. all pins are made of high-strength alloy steel and are specially treated ,so they have very high wear-resistance ability .the temperature of barrel is controlled by three sets of TCU.

3、The extruder base is designed with two-layer and integrated structure with railway .the base is welded with shape steel and steel plate, its advantages include simple structure ,good appearance , stable and reliable performance and convenient adjustment . the removement of Extruder together with upper layer base ,away from or near to calendar, is very convenient for cleaning stock in case of changing sheet size.

4、The gear of speed reducer has alloy steel hard tooth flank. The transmission precise level of gear is high , with features of anti-wear , low noise and long service life.

5、The motor adopts DC motor ,with performance of encoder feedback , air cooling and overheat protection .the driving is realized by full-digital DC speed adjusting device.

6、The head assembly can be cooled or heated by going through water . upper and lower components of head are connected by hinges .all the actions of opening closing ,clamping and release are driven by hydraulic oil cylinders . every side of head channel has insert ,which can be replaced depending on needed stock output width at head .thus guarantee the calendar to produce various width of sheet .the temperature of head is controlled by one set of TCU.

7、There is stock-lacked alarming device and extruder with adjustable speed on the feeding frame to ensure continuous delivery of stock.
