Rubber Extruder/China Extruder/Rubber Rubber Extruder (XJ-120)
Usage:
1- extruding tires of tread in radial tire and cross-ply tire preparation, extruding bead apex, covering rubber of electric wire, electric cable and rubber hose, extruding rubber board, slab, conveyer belting and rubber core.
2- Also the extruder is widely used for feeding rubber on steal cord calendaring line, feeding rubber for radial tire's airtight seal.
3- The material of all screw shafts and liners is 38CrMoAlA high-quality steel,
the surface of them is processed by nitrogen treatment and the hardness HRC is 60-65.
4- Their resistance to wear and corrosion is very good. The direct current motor is applied to infinite speed variation in transmission agent. Reduction is a hard tooth face cylinder gearwheel reducer.
The transmission is stable and reliable. The agent has small volume and low noise.
5- Temperature control system:
The extruder uses the technology of room temperature feeding. Its advantages are high quality, high yield ability, high efficiency and energy conservation. Also the extruder can extruder rubber at low temperature, and is highly adaptable to processes of tires of rubber sizing material. The extruder is the first choice machine while technology innovating, process improving and equipment replacing in rubber industry.
6- Also we make machine follow CE,ISO9001 procedure,each section is inspection by our QC.
Complete after sale service, we keep two year warranty, and track machine whole life use.
Rubber seals production line extruding process is including many machines, as cold feed rubber extruder, automatic thermostat circulating vulcanizing box, cooling tank, roller traction machine, duplex winding machines and other equipments. This production line has the advantage of labor, effort and energy-saving, environmental protection and high capacity etc.
Automatic thermostat circulating vulcanizing box adopts automatic thermostat temperature control system which has character of fast heating and high production efficiency etc.
1. Electric heating tube heating, temperature range as the room temperature to 260° C, the entire line automatic thermostat, and temperature control accuracy of +/-2 ° C.
2. Effective length of the vulcanizing box generally is 26 meters. It liner with 120stainless steel and the middle insulating layer is fully filled with aluminum silicate cotton.
3. Vulcanization box is divided into three zones, each zone with trimmer potentiometer which adjusts the speed of the three zones of vulcanizing box to equilibrium; In the middle of each zone with the ventilating device, and removing the emissions generated by the vulcanization process in time in order to ensure the smoothness of the rubber products.
4. Cooling tank is used to cool high temperature rubber seals and then use high-speed airstream drying them.
5. The entire production line speed is adjustable to match with speed of the extruder.
