XY-211300 rubber two-roll calender:

Characteristic:
1.The upper roll and lower roll are arrange in-type. the surface of roll is precisely machined having high precise and good wear-resistance . peripheral drilling bores on roll can ensure even temperature on working surface .two ends of roll are supported by precise two –row cylinder roll bearings.
2.The upper foo is designed to be profile-sleeve replaceable structure ,installed with profile sheet ,installed with smooth sleeve for producing flat sheet . the sleeve can be moved and replaced quickly though hydraulic manipulator.
3.The lower roll has axis cross device to rectify the thickness uniformity lf stock sheet.
4.5、 Roll nip adjusting device ,which is set on bearing body of lower roll ,can adjust left/right nip of rolls simultaneously ,as well as adjust left or right nip separately.
5.In the front of calender ,there are two cutting discs,taking centering lf shape roll as symmetrical centerline ,they are mounted on left-hand and right-hand thread separately ,which can be regulated by power control button .the cutter device has a scale used for determining distance of cutters .
6.A convey belt for recycling leftover material is mounted on top of calender ,is used to feed the cut leftover material into the hopper of extruder .a pressing roll is set at the entrance of belt for ensuring the leftover material attached on the convey belt.
7.The gear of speed reducer is alloy steel hard tooth flank gear . the transmission precise level of gear is equal to or more than grade 6,with features of anti-wear ,low noise and long service belt.
8.Adopt DC motor with encoder and wind cooling and overheat protection . motor is driven by full –digital DC speed adjusting device.

XY-F211200A rubber inner liner extruding and calendaring (cold coating)accessory units:
The accessory units include take up, cooling device, surface friction winder ,front over head conveyer belt , double-station left- off unit ,splicing unit, centering device, coating and cutting device, rear over head belt ,and double –station wind-up unit etc.
Characteristic:
1.Also,the infrared temperature monitoring device , CCD width measuring device and laser thickness measuring device can be mounted on the take-off device.
2.The surface of cooling roll is made of stainless steel and been anti-stick treated , so it is smooth and anti-corrosion, the inner adopts jacket and axial flow structure ,the rotary unions of water inlet and outlet are mounted in the non-operation side.
3.The machine is welded with all kinds of shape steel.
4.The coating device ,taking the cooled rubber sheet on upper layer of front overhead as reference ,taking lower layer sheet (from let-off) as accessorial sheet , has the profiled sheet centered and cold coated together under the control of CCD system.
5.The winding and centering device adopts CCD error correcting system to make the wind-up unit center with stock sheet to guarantee rubber to be tidily winded up.
6.There are two sets of completely same let-off unit and wind-up unit in this production line to ensure continuous production.
7.There are one double –station friction wind-up unit for winding up thin rubber sheet .


inner liner extruding and calendaring (hot coating ) accessory units :
1.The accessory units will cooperate with two sets(primary/auxiliary ) of ￠200 pin cold feed extruder two sets (primary /auxiliary)of XY-211300 rubber two-roll calender in producing wind-type two-layer hot coating rubber inner liner thin sheet.
2.The calendaring accessories consists of main take-up device .incline-up conveyer belt , auxiliary take-up device , centering device , coating device ,machine frame ,cooling device, cooling conveyer belt , platform , incline-down conveyer belt , cutting device , cutting conveyer belt, movable conveyer belt and double-station wind-up device.
3.The production flow is :firstly coat, then cool ,lastly wind up.two sets of main machine is equipped with one set of auxiliary machine ,so it has high-efficiency production (equivalent to two sets of cold coating production line ),lower cost (compared with two sets of cold coating production line ) and high product quality.

Characteristic:
1.The sheet from main machine is conveyed onto the incline –up conveyer belt by take-up device.
2.Also, the infrared temperature monitoring device ,CCD width measuring device and laser thickness measuring device can be mounts on the take –off device .
3.Two layers of sheet are delivered onto the coating device and coated together under CCD control .then it is sent onto about 100-meter long conveyer belt to be cooled by man-made cool air.
4.The winder and centering device of this machine adopted CCD error correcting system , make the wind-up unit center with stock sheet to guarantee stock sheet to be tidily winded up. There is infrared error correcting system on lining let-off device to ensure that the lining is tidy after the sheet is winded up.
5.For continuous producing sheet ,double –station wind up unit is available .
