Description
Technical field
The utility model belongs to the shaping of plastics or connection area, is specifically related to the extrusion mechanism of a kind of Rubber processing.
Background technology
Early stage rubber is the latex taking from the plant such as rubber tree, russian dandelion, the material with elasticity, insulativity, waterproof and air made after processing. Elastomeric macromolecular compound is divided into natural rubber and synthetic rubber two kinds. Natural rubber extracts colloid post-treatment from the plant such as rubber tree, russian dandelion to make; Synthetic rubber is then obtained through polyreaction by various monomer.
Rubber industry is one of important foundation industry of national economy. It is not only the light industry rubber product such as daily, medical that people provide daily life indispensable, and provides various rubber production unit or rubber components to the heavy industry such as digging, traffic, building, machinery, electronics and new industry. Visible, the product category of rubber industry is various, and backward industry is very wide.
The processing of rubber generally include plasticate, mixing, roll or extrude, the basic working procedure such as shaping and sulfuration, each operation has different requirements for goods, coordinates respectively with some non-productive operations. In order to add in rubber by various required Synergist S-421 95, first rubber needs to improve its plasticity through plasticating; Then by mixing, carbon black and various rubber ingredients and rubber are uniformly mixed into sizing material; Sizing material makes a shaped blank through extrusion; Make it combine with the textile materials (or and metallic substance) through calendering extension glue or gluing again and it is shaped to work in-process; Eventually pass sulfuration and again the work in-process with plasticity are made elastomeric the finished product.
Rubber extruding operation is normally extruded in extrusion mechanism, but in the process extruded, under the effect of friction, rubber surface easily produces electrostatic, like this in follow-up manufacturing procedure, it is easy to attracting debris, hair etc., thus seriously affects follow-up processing.
Practical novel content
The purpose of this utility model is to provide the extrusion mechanism of a kind of Rubber processing, and this extrusion mechanism can prevent rubber surface from producing electrostatic, thus avoids the impact on following process.
For achieving the above object, base case of the present utility model is as follows:

The principle of this scheme: when specifically using, start propulsion source and oil-feed pump, propulsion source drive shaft is rotated, and outside silicone oil pump is entered in the first annular recesses 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 annular recesses spills through the distribution hole of rubber ring or rubber ring, and is coated in the rubber surface being extruded.
The advantage of this scheme is: in this scheme, in the process that rubber raw materials is continuously extruded, the distribution hole of silicone oil in the first annular recesses on rubber circle or rubber ring, it is 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 annular recesses cross section radially is the conical surface. When the cross section of the first annular recesses is above-mentioned shape, after rubber ring or rubber ring are installed, the first annular recesses can separately be formed two portions by rubber ring or rubber ring, thus prevents the silicone oil in the first annular recesses from directly spilling.
Prioritization scheme 2, to the further optimization of base case, described extruder head inwall is also provided with second ring groove, is provided with the rubber circle for scraping even silicone oil in this second ring groove. The silicone oil spilt from rubber ring or rubber ring is coated in the surface of rubber, but coating is uneven, by arranging second ring groove and rubber circle, can scrape even by the silicone oil being coated in rubber surface like this.
Prioritization scheme 3, to the further optimization of base case, prioritization scheme 1,2 arbitrary, described extruder head inwall is provided with pyroceramic layer. In the process extruded, friction and squeeze between rubber raw materials and extruder head inwall are relatively big, under the effect rubbed and extrude, can produce a large amount of heats, easily cause the inner wall deformation of extruder head, refractory alloy layer is set and then can prevent 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 rubber to the power of the extruding of distribution hole.
