Background technology
Extrusion molding occupies very consequence in plastic product forming processing industry.According to statistics, in plastic product forming processing, the output of extrusion moulding product ranks first.With other forming methods relatively, extrusion molding has serialization production, productivity ratio height, be widely used the characteristics with smail investments and quick rerurn.Along with plastic extruding forming broad application and development, the type of extruder is increasing.
Extruder high speed, high yield can make the investor obtain the bigger output and the repayment of great number with lower input.Extruder efficiently be mainly reflected in high production, low energy consumption, low manufacturing cost aspect.In function aspects, screw extruder not only is used for the extrusion molding and the mixing processing of macromolecular material, and its purposes has been widened fields such as food, feed, electrode, explosive, building materials, packing, paper pulp, pottery.
But, the difficult point that extruder screw rotating speed high speed has also brought a series of needs to overcome: it is uneven that time of staying minimizing in screw rod can cause the mixing plasticizing of material as material, the excessive shear that stands material may cause hurried intensification of material and thermal decomposition, extrude stability control difficulty and can cause the fluctuation of extrudate physical dimension, the relevant servicing unit and the precision of control system must improve, the wearing and tearing of screw rod and machine barrel aggravation needs to adopt high abrasion and superelevation wear-resistant material, and how decelerator and bearing improve problem such as its life-span under situation about running up all need solution.
In addition, realize that the maximization of extrusion equipment can reduce production costs, this is more obvious in aspect advantages such as large-scale twin-screw granulation unit, blown film unit, pipe extruder groups.Yet, the major technologies and equipment that state key construction service is required, the large-sized squeezing granulation unit of one of three big key equipments that large-scale ethylene project is supporting still relies on import for a long time, therefore must increase the proportion of domestic goods more quickly, and satisfies the petrochemical industry development need.And precise treatment can improve the gold content of product, all needs precision to extrude as multi-layer co-extruded laminated film etc., and as realizing the accurate important means of extruding---the smelt gear pump research of must going into overdrive to develop.
All round realizing more efficient, more energy-conservation production, this has also just confirmed the inexorable trend of extruding technology development in the innovation of extruding technology.The expert thinks that the market of the modern Hou of extruder main frame and production line will be developed to the direction that high technology content, price more become to dropping.And ultra-large type, superminiature, big L/D ratio, high production, good venting quality etc. become the development defence line of extrusion equipment already, and adapt to the spiro rod machine tube structure of special processing needs, also become the emphasis that everybody falls over each other to research and develop.
Along with the continuous development of extrusion technology, constantly increasing of extruder type is new, and novel extrusion technology will be brought into play its important function day by day.
Summary of the invention
The purpose of this invention is to provide many extruders of a kind of collection is one, can realize rapidly and efficiently the integration type extruder and the moulding process thereof of precision extrusion molding.

Extrusion system can adopt the extrusion system of single screw rod or twin-screw or multi-screw extruder, also can adopt the extrusion system of reciprocating screw extruder or mill extruder.The type of its a plurality of extrusion systems can be the same or different.
Extrusion system can adopt single screw rod, twin-screw, multi-screw extruder, reciprocating screw extruder or mill extruder two or more types wherein to form.
Heating-cooling device heats planetary gear pump and controls its temperature, with the smooth and easy circulation that guarantees that plastic melt can be in pump, integrating system be mainly used in high-temperature fusant conveying, compile, supercharging and metering.
Can select the planetary gear pump of existing high-precision measuring for use, it can guarantee stable repeated flow under the condition of all temps, viscosity, pressure, realizes the purpose of high-precision measuring.
The cooling/heating apparatus of integrating system adopts heating rod, heating collar or heater strip.Can conveniently do repacking to planetary gear pump like this, the hole of adopting heating rod promptly to place heating rod in pump housing processing gets final product; Adopting the heating collar suitable heating collar of promptly selecting size to be wrapped on the pump housing gets final product; Adopting heater strip promptly to embed heater strip on pump housing two sides gets final product.
The extruding-out process process that integration type extruder of the present invention is realized is its extrusion with the difference of conventional extruding-out process process.In extrusion, plastics, enter in the import of planetary gear pump of integrating system via the front end exit of extrusion system under pressure, and enter in the pump housing in machine barrel behind the fusion plastification through extrusion system; The controller control drive motors work of integrating system, drive master gear and pinion work through the shaft coupling gear shaft, promptly drive the planetary gear pump work, plastic melt flows out from outlet through planetary positive battery metering effect, and compile and enter primary outlet, enter moulded products in the head again; Finish the extrusion of integration type extrusion molding thus; Extrusion simultaneously needs heating-cooling device to the planetary gear pump heating and be controlled at proper temperature, to guarantee that plastic melt can fully flow therein under molten condition.
The present invention still adopts the extrusion system of conventional extruder, therefore can directly improve common extruder, especially middle-size and small-size extruder, utilize integrating system that a plurality of small-sized extruders are compiled and be one, can constitute the integration type extruder, realize the function of high speed extruder, medium-and-large-sized extruder even ultra-large type extruder.
The present invention enters integrating system owing to adopted a plurality of extrusion systems to supply with material simultaneously, feed is fast and sufficient, therefore can under the situation of extruder screw low speed rotation, obtain the function of high speed extruder, under the situation of screw rod low speed, just avoid uneven, the easy thermal decomposition of the mixing plasticizing of material, extruded a series of defectives such as stability is controlled difficulty, spiro rod machine tube is easy to wear, the life-span is low; Can realize function large-scale, the ultra-large type extruder, highly efficient and productive, energy-conservation, avoided again producing technical difficulty large-scale, the ultra-large type extruder big, make defectives such as processing difficulties, materials are many, only need to be equipped with corresponding large-scale integration system and get final product; And adopted planetary gear pump, therefore the control metering is accurately.
