The principle of this programme: when specifically using, start power source and oil-feed pump, power source drive shaft is rotated, and outside silicone oil pumps in first ring connected in star by oil-feed pump, is then added from loading hopper by rubber raw materials to be extruded, rubber raw materials enters extruding cavity, under the effect of feeding screw, rubber raw materials moves towards discharging one end, when rubber raw materials is extruded from extruder head, silicone oil in first ring connected in star spills through the distribution hole of elastic tape or rubber grommet, and is coated in the rubber surface be extruded.
The advantage of this programme is: in this programme, in the process that rubber raw materials is continuously extruded, the distribution hole of silicone oil in first ring connected in star on rubber ring or rubber grommet, be coated in the surface of extruded rubber, like this in the following process of rubber, even under the effect of friction, rubber surface can not produce electrostatic, so just can prevent rubber surface from producing electrostatic, thus avoid the impact on following process.
Prioritization scheme 1, to the further optimization of base case, described first ring connected in star cross section is radially the conical surface.When the cross section of first ring connected in star is above-mentioned shape, after elastic tape or rubber grommet are installed, first ring connected in star separately can be formed two parts by elastic tape or rubber grommet, thus prevents the silicone oil in first ring connected in star from directly spilling.
Prioritization scheme 2, to the further optimization of base case, described extruder head inwall is also provided with the second annular groove, is provided with the rubber ring for drawout silicone oil in this second annular groove.The silicone oil spilt from elastic tape or rubber grommet is coated in the surface of rubber, but coating is uneven, by arranging the second annular groove and rubber ring, can be coated in the silicone oil drawout of rubber surface like this.
Prioritization scheme 3, to the further optimization of base case, any one of prioritization scheme 1,2, described extruder head inwall is provided with refractory ceramics layer.In the process extruded, friction between rubber raw materials and extruder head inwall and extruding force are comparatively large, under the effect rubbed and extrude, can produce a large amount of heats, easily cause the inner wall deformation of extruder head, heat-resisting alloy layer is set and then can prevents the inwall of extruder head from deforming.
Prioritization scheme 4, to the further optimization of prioritization scheme 3, described distribution hole is reducing shape along discharging direction.When distribution hole is above-mentioned shape, the pressure of the silicone oil spilt from distribution hole can increase gradually, thus overcomes the power of rubber to the extruding of distribution hole.
