China Rubber Extruder

rubber extruder
rubber extruder from semi-product, fitter rubber compound and cable encapsulation of tabletting and wire.
rebber extruder, the machine is mainly used for forming rubber seml-product, flltering rubber compounds and cable encapsulation .it also can be used for encapsulation of tabletting and wire
the machine is not-feed single extruder
the structure features of this machine is that the rational speed can be adjusted, a variety of extruding semi-finished product registration ,tabletting and filter encapsulation can be obtained in the situation of changing extruder head, so it's application is wider.
the machine is mainly composed of extruding device, heating and cooling device, transmission device ,electric appliance part and machine heat, etc.
Description:
1. Screw is made of best 38CrMoALA, its hardness is higher generally than HRC62 ( 60-65 ), Depth of nitrogen is higher than 0.55-0.7 mm ( 0.4-0.7 )
2. Bush is also made of 38CrMoALA, its hardness is generally higher than HRC66( 65-70 ), Depth of nitrogen is generally higher than 0.55-0.7 mm ( 0.4-0.7 mm )
3. Feeding device is made of feeding roller and feeding barrel, Feeding roller is driven by gears and its structure resembles Italy type. The rubber will never leak out, then it is never impossible for that the rubber enters into the bearing bush.
4.the rubber strainer can be used in different applications,including single head,doublehead ,hot feed,cold feed.
5.the machine ody is equipped with a temperature retulation device.the screw and bushes are subjected to nitrogenation treatment to get enough strength and excellent wear-resistance.
6.the head is fitted with a mechanical cutter,which operates hydraulically,the operation is sample and easy.
