With cutting machine etc., wherein extrusion main unit is the equipment the closest with the property relationship of double-wall corrugated pipe, now double-wall corrugated at present
Extrusion equipment in extrusion main unit used by the process equipment of pipe is single screw rod and two kinds of incorgruous conical double-screw, wherein
Single screw rod existing defects are: (1) single screw rod is generally saturated feeding, and delivery precision is poor, and tubing weight is unstable；(2) single spiral shell
Bar does not have degassing function, more demanding to the drying of material.To solve the above-mentioned problems, someone uses incorgruous conical double ribbon
Bar, still, incorgruous conical double-screw equally exist defect: due to the design feature of conical screw, head pressure is to conical screw
It is affected with gear-box, after head operating pressure excessive (being greater than 10MPa), conical screw is easily snapped off, gear-box is easy damage
Bad, service life is lower；Meanwhile the type screw speed is lower, causes plasticizing capacity limited, yield is significantly less than single screw rod, no
It is able to satisfy production requirement.
Summary of the invention
The object of the present invention is to provide a kind of double-wall corrugated pipe systems of processing using co-rotating conical twin-screw.This hair
Both there is bright system tubing weight to stablize, and dry materials be required with low feature, and have long service life, plasticizing capacity
By force, the big feature of yield, can satisfy production requirement.
Technical solution of the present invention: a kind of double-wall corrugated pipe system of processing using co-rotating conical twin-screw, by successively connecting
Blender, dryer, feeding device, extruder, cutting machine and the cooling device composition connect；Wherein the extruder is to bore in the same direction
Shape double screw extruder, the extrusion die of extruder front end are low pressure extrusion die；The cooling device includes and cutting machine
The guide rack of coaxial arrangement is imported and exported, the lower section of guide rack is equipped with cooling trough, and guide rack is hinged in the upper of support frame
End, the lower end of support frame are fixed on cooling trough, and stirring pushing meanss are equipped between guide rack and support frame.
Double-wall corrugated pipe system of processing above-mentioned using co-rotating conical twin-screw is equipped at the feed inlet of the extruder
Weightlessness claims.
Double-wall corrugated pipe system of processing above-mentioned using co-rotating conical twin-screw, the low pressure extrusion die are that pressure is small
In the die head of 10MPa.
Double-wall corrugated pipe system of processing above-mentioned using co-rotating conical twin-screw, the feeding device are screw feeding machine
Or conveyer belt feeder.
Double-wall corrugated pipe system of processing above-mentioned using co-rotating conical twin-screw, the guide rack are two pieces of symmetrical arcs
Shape plate one and arc panel two, arc panel one and the opposite outside of arc panel two are respectively hinged at the upper end of support frame, arc panel one
Stirring pushing meanss are respectively equipped between the opposite outside and its ipsilateral support frame of arc panel two.
Double-wall corrugated pipe system of processing above-mentioned using co-rotating conical twin-screw, the arc panel one and arc panel two-phase
Pair inside be respectively equipped with along bellows moving direction rotation support roller.
Beneficial effects of the present invention
1, the present invention uses double screw extruder, solves previous single screw rod and squeezes out the tubing weight occurred in bellows production process
Unstable disadvantage is measured, has the advantages that tubing weight is stable；
2, the present invention wants degree of drying to reduce material using saturation feeding after double screw extruder, is not needed
It asks, it is lower to have the advantages that dry materials require；
3, double screw extruder of the invention is that co-rotating conical twin-screw can substantially reduce after low pressure extrusion die of arranging in pairs or groups
The pressure of head extends the service life of screw rod, gear-box；
4, after structure of the present invention by improving extruder, the revolving speed of screw rod can be greatly improved, to substantially increase to object
The plasticizing and kneading ability of material, and the output of system is improved, it can satisfy the demand of mass production.
5, the present invention further stabilizes the conveying of material, makes tubing weight more by preparing weightless title on extruder
Add stabilization, while also optimizing the operating condition of extruder, effectively reduces the damage to equipment.
6, the present invention also improves cooling system, is different from the basis of improving the speed for squeezing out bellows
Traditional cooling system, since traditional processing line extruded velocity is slow, using spraying cooling first after extrusion, then
The mode cut off again.But the present invention, after significantly improving extruded velocity, such type of cooling can not meet fast fast-growing
Therefore the demand of production is applied through above-mentioned scheme, be directly initially switched off after pipeline extrusion, then at once by the ripple of cutting
Pipe is ploughed under in cooling trough and is cooled down, and traditional mode cooled down when squeezing out is just changed in this way, so that extruded velocity is complete
It is not influenced entirely by cooling velocity, to substantially increase the speed of production.
