Description
Technical field
The present invention relates to a kind of macromolecular material extrusion equipment, the helical gearing cold feed extruder of particularly a kind of suitable rubber or plastic extruding forming.
Background technology
Rubber Extruder is one of the most basic former of rubber processing moulding, extensively is used in tire manufacturing, sebific duct manufacturing, sealing strip manufacturing, electric wire manufacturing and the waterproof sheet manufacturing of rubber industry.
The rubber hot-feed extruder appearred in the eighties in 19th century, because it is simple in structure, production efficiency is high, easy to manufacture and can the serialization operation etc. unique advantage, make that hot-feed extruder obtains to use widely in rubber industry, and become the visual plant of rubber industry, and therefore in rubber industry, occupy ascendancy for 100 years.But, because hot-feed extruder needs a whole set of huge preheating for colloid system, not only make complex technical processization, and unsurmountable shortcoming is all arranged in the consumption of floor space, electric energy, labour's waste etc., particularly hot feeding extrusion screw rod draw ratio is very short, be difficult to set up head pressure, it is loose to cause extruding the semi-finished product quality, directly influences the quality of rubber finished product.
In order to overcome the problem that hot-feed extruder exists, rubber Cold-feed extruder has been invented at initial stage 1940's by Germany, this extruder has strengthened the draw ratio of screw rod on original hot-feed extruder basis, make the outer sizing material heat refining of extruder machine become the interior heat refining function of extruder machine for the glue function.Thereby, can cancel the required huge heat refining of hot-feed extruder for colloid system; Also improved simultaneously the head pressure of extruder.Make and extrude the densification of semi-finished product quality, improved Products Quality.Yet its screw configuration of early stage cold feed extruder is fairly simple, generally is to wait the dark equidistant or equidistant dark common screw that do not wait.Such screw rod mainly has been the conveying effect, and its shearing, mixed function are relatively poor; Neglected the importance of each section heated at constant temperature of cold feed extruder in addition at that time, and caused extruding the sizing material plasticizing and do not reach requirement.Therefore, this plain edition cold feed extruder slowly can not get promoting in rubber industry, and its purposes also only is confined to the multiple glue of cable and wire.
Through 20 years of development, the powerful shear screw of major-minor screw thread, the also corresponding major-minor screw thread cold feed extruder that occurred have appearred in industrialized country in phase early 1960s.The appearance of this class cold feed extruder is significantly improved the shearing function and the mixed function of extruder, can set up higher head pressure simultaneously, and this has just broken through the plasticizing capacity problem that cold feed extruder never solves.This period, cold feed extruder began to obtain developing more rapidly.Though major-minor thread screw cold feed extruder plasticizing capacity is improved, its production capacity is on the low side and the higher problem of extrusion temperature is restricting its development.
