Rubber Inner LinerExtruding Calendering Line

XJD-200×16pin Cold Feed Extruder

Features

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

2. Thebarrel of the extruder is drilled on the wall to put through water for heatingor cooling. The liner is made of double-metalmaterial, having high hardness and good wear-resistance. All pins are made ofhigh-strength alloy steel and are specially treated so they have very highwear-resistance ability. The temperature of the barrel is controlled by threesets of TCU.

3. Theextruder base is designed with two-layers and integrated structure withrailway. The base is welded with shape steel and steel plate and its advantagesinclude simple structure, good appearance, stable and reliable performance andconvenient adjustment. The removal of the extrudertogether with upper layer base, away from or near to calender,is very convenient for cleaning stock in case of changing sheet size.

4. Thegear of speed reducer has an alloy steel hard tooth flank. The transmissionprecise level of gear is high, with features of anti-wear, low noise and longservice life.

5. Themotor of the rubber inner liner extruding calenderingline has a DC motor, with performance of encoder feedback, air cooling andoverheat protection. The driving is realized by a full-digital DC speedadjusting device.

6. Thehead assembly can be cooled or heated by going through water. The upper andlower components of the head are connected by hinges. All the actions ofopening, closing, clamping and release are driven by hydraulic oil cylinders.Every side of the head channel has an insert, which can be replaced dependingon needed stock output width at the head. This guarantees that the calender will produce various widths of sheet. Thetemperature of the head is controlled by one set of TCU.

7. Thereis a stock-breaking alarming device and extruder withadjustable speed on the feeding frame to ensure continuous delivery of stock.

Application

The rubber inner line extruding calenderingline consists of ￠200 pincold feed extruder and XY-211300 rubber two-roll calendar, equipped with allkinds of accessory units to produce two-layer hot-combined inner liner,two-layer or three-layer cold-combined inner liner, and single-layer thinrubber sheet, which will be supplied to radial tire or bias tire buildingmachine or multi-cutter slitting machine.

Technical Specifications of the Rubber Inner Line Extruding Calendering Line

XY-211300Rubber Two-Roll Calender

Features

1. Theupper roll and lower roll are arranged in-type. The surface of roll isprecisely machined having high precision and good wear-resistance. Peripheral drillingbores on the roll can ensure even temperature on the working surface. Two endsof roll are supported by precise two–row cylinder roll bearings.

2. Theupper roll is designed to be a profile-sleeve replaceablestructure, installed with profile sheet, installed with smooth sleeve forproducing flat sheet. The sleeve can be moved and replaced quickly thoughhydraulic manipulator.

3. Thelower roll has an axis cross device to rectify the thickness uniformity.

4. The roll nip adjusting device, which is set onbearing body of lower roll, can adjust left/right nip of rolls simultaneously,as well as adjust left or right nip separately.

5. Inthe front of the calender, there are two cuttingdiscs, taking centering if shape roll as symmetrical centerline; they aremounted on left-hand and right-hand thread separately, which can be regulatedby a power control button. The cutter device has a scale used for determiningthe distance of cutters.

6. Aconvey belt for recycling leftover material is mounted on top of the calender. It is used to feed the cut leftover material intothe hopper of the extruder. A pressing roll is set at the entrance of the beltfor ensuring the leftover material attached on the convey belt.

7. Thegear of speed reducer is alloy steel hard tooth flank gear. The transmissionprecise level of gear is equal to or more than grade 6, with features ofanti-wear, low noise and long service belt.

8. Ituses a DC motor with encoder, wind cooling and overheatprotection. The motor is driven by a full–digital DC speed adjusting device.

Technical Specifications

XY-F211200A Rubber Inner LinerExtruding and Calendering (Cold Coating) AccessoryUnits

Features

1. Theinfrared temperature monitoring device, CCD width measuring device and laserthickness measuring device can be mounted on the take-off device.

2. Thesurface of the cooling roll is made of stainless steel and has been anti-sticktreated, so it is smooth and anti-corrosion. The inner uses jacket and axialflow structure, the rotary unions of water inlet and outlet are mounted in thenon-operation side.

3. Themachine is welded with all kinds of shape steel.

4. Thecoating device, taking the cooled rubber sheet on upper layer of front overheadas reference, taking lower layer sheet (from let-off) as accessorial sheet, hasthe profiled sheet centered and cold coated together under the control of CCDsystem.

5. Thewinding and centering device uses a CCD error correcting system to make thewind-up unit center with stock sheet to guarantee that the rubber will betidily winded up.

6. Thereare two sets of completely same let-off unit and wind-up unit in thisproduction line to ensure continuous production.

7. Thereis one double–station friction wind-up unit for winding up thin rubber sheet.

Application

The accessory unitsinclude take up, cooling device, surface friction winder, front over headconveyer belt, double-station left-off unit, splicing unit, centering device,coating and cutting device, rear over head belt, and double–station wind-upunit, etc.

XY-F211200B Rubber InnerLiner Extruding and Calendering (Hot Coating)Accessory Units

Features

1. Theaccessory units will cooperate with two sets (primary/auxiliary) of ￠200 pin cold feed extruder and two sets (primary/auxiliary)of XY-211300 rubber two-roll calender in producingwind-type two-layer hot coating rubber inner liner thin sheet.

2. Thecalendering accessories consist of a main take-updevice, 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, movableconveyer belt and double-station wind-up device.

3. Theproduction flow is: first coat, then cool, and wind up. Two sets of mainmachine is equipped with one set of auxiliary machine, so it has high-efficiencyproduction (equivalent to two sets of cold coating production line), lower cost(compared with two sets of cold coating production line) and high productquality.

Features

1. Thesheet from the main machine is conveyed onto the incline–up conveyer belt bytake-up device.

2. Theinfrared temperature monitoring device, CCD width measuring device and laserthickness measuring device can be mounted on the take–off device.

3. Twolayers of sheet are delivered onto the coating device and coated together underCCD control. It is then onto about 100-meter long conveyer belt to be cooled byman-made cool air.

4. Thewinder and centering device of this machine use a CCD error correcting system,make the wind-up unit center with stock sheet to guarantee stock sheet to betidily winded up. There is an infrared error correcting system on lininglet-off device to ensure that the lining is tidy after the sheet is wound up.

5. For continuous producing sheet, a double–stationwind up unit is available.
