Abstract
The utility model relates to a spiral conveying mechanism of extruding machine capable of improving extruding efficiency, which comprises a connecting flange, an outer lining, an inner spiral conveying lining; the inner spiral conveying lining is mounted inside the outer lining and the connecting flange is disposed at one end of the outer lining, and a spiral cooling flow channel is disposed on a joint surface of the outer lining and the inner spiral conveying lining; and the outer lining is provided with a cooling inlet and a cooling outlet respectively, and is also provided with a temperature control temperature measuring point. The spiral conveying mechanism has the characteristics of contributing to realization of high-efficiency extrusion, getting excellent plasticization, improving specific discharge and reducing specific power consumption; the material conveying fluctuation and the shearing abrasion can be greatly reduced so as to avoid the problem on the melt fracture of the material and the bridging phenomenon of the material inlet, improve extruding accuracy and ensure stable extruding performance of the product; the recess phenomenon caused by extrusion and strong force friction on the bottom of the material hole is reduced, and the service life of the product is prolonged; and extruder screws with different functions can be configured.
Description
Technical field
The utility model relates to the plastic extruder technology, relates in particular to a kind of extruder spiral conveying mechanism that improves extrusion efficiency.
Background technology
In the plastics extrusion; The conveying mechanism of single-screw extruder directly influences the service life of extrusion efficiency and the material plasticizing effect and the equipment of plastics single screw extrusion machine; The structure for conveying incompatibility of existing plastics single screw extrusion machine is efficiently extruded, its energy consumption is high, the induction system serious wear; Concrete defective is presented as: (1) extrusion system adopts and heads straight for the groove structure for conveying; This structure can make mass transport fluctuation and shear serious wear, also causes broken problem of material melt and charging aperture arch formation easily in advance, extrudes the high product of required precision and is difficult to assurance and extrudes stability thereby make; (2) existing extruder straight channel type structure for conveying is that mass transport is gone into to head straight for the groove structure for conveying; Material promotes forward after getting into behind the straight trough structure for conveying lining and shearing through friction; Material overcomes the solid plug of shearing friction formation and promotes material forward, so this mode of movement energy consumption is big, and efficient is low; (3) traditional straight channel type conveying mechanism is when carrying; Be after material gets into the lining straight trough, to rely on screw rod spin friction convey materials; Set up high pressure differential this moment, owing in pressure and shear time and position that this charging place is set up in advance, make a material mouthful blanking place be easy to generate extrusion abrasion; Cause the charging aperture bottom to produce concave surface, the service life of having reduced product.
The utility model content
To above defective, the utility model provides a kind of and improves extrusion efficiency, makes that plasticizing is good, help extrusion stable extrude spiral conveying mechanism, to solve many deficiencies of prior art.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of extruder spiral conveying mechanism that improves extrusion efficiency; Comprise adpting flange, external bushing, inside spin conveying lining; Said external bushing inboard pack into inside spin carry lining and this external bushing wherein an end be furnished with adpting flange, be positioned at the two faying face position of external bushing and inside spin conveying lining and be provided with the spiral coolant flow channel; Offer cooling import and coolant outlet on the said external bushing.
For above technical characterictic, also comprise: said inside spin is carried the leading section on composition surface between lining and the external bushing sealing ring of packing into; Temperature control point for measuring temperature also is set on the said external bushing.
Compared with prior art, the described beneficial effect that improves the extruder spiral conveying mechanism of extrusion efficiency of the utility model is:
(1) through this structure is set, help realizing efficiently extruding, plastifying good, improve specific discharge and reduce characteristics such as specific power consumption; Especially the specific discharge of extruder can be much higher than structure in the past, improves specific discharge greater than 30%, and specific power reduces by 20% one 30%;
(2) can make mass transport fluctuation and shear wearing and tearing and reduce greatly, thereby avoid material melt broken problem and charging aperture arch formation, improve and extruded precision and guaranteed that product extrudes stability;
(3) after material gets into the lining helicla flute; Rely on screw rod spin friction convey materials; The pressure differential and the shear effect at blanking port place have been reduced this moment; Thereby make the blanking place reduce extrusion abrasion, reduced material mouthful bottom owing to push the recess phenomenon that produces with powerful friction, the service life of having improved product;
(4) extruder screw of configurable difference in functionality, so adaptability is stronger, uses extensively, is particularly suitable for disposing extruding of the full-bodied TPO material of adaptation.
Description of drawings
According to accompanying drawing the utility model is done further explain below.
Fig. 1 is the said extruder spiral conveying mechanism sketch map that improves extrusion efficiency of the utility model embodiment;
Fig. 2 is the said partial side view of improving the extruder spiral conveying mechanism of extrusion efficiency of the utility model embodiment.
Among the figure:
1, adpting flange; 2, bolt; 3, back bush; 4, external bushing; 5, inside spin is carried lining; 6, sealing ring; 7, cooling import; 8, coolant outlet; 9, temperature control test point; 10, spiral coolant flow channel; 11, thread barrel positioning end.
The specific embodiment
Shown in Fig. 1-2; The described extruder spiral conveying mechanism that improves extrusion efficiency of the utility model embodiment; Comprise adpting flange 1, external bushing 4, inside spin conveying lining 5; Said external bushing 4 inboards pack into inside spin carry lining 5 and this external bushing 4 wherein an end be furnished with adpting flange 1, this adpting flange 1 is fixedly connected with external bushing 4 through bolt 2; Said inside spin carries the leading section between lining 5 and the external bushing 4 to pack sealing ring 6 into to realize the sealing of cooling medium; The inside spin that is positioned at adpting flange 1 one sides carries lining 5 outsides to be provided with back bush 3; This adpting flange 1 is connected with the transmission mechanism of extruder, again power is inputed to extrusion system.In addition; For improving transfer efficiency and reducing thermal energy consumption; Being positioned at external bushing 4 carries lining 5 the two faying face position to be provided with spiral coolant flow channel 10 with inside spin; And offer cooling import 7 and coolant outlet 8 on the said external bushing 4 respectively, be positioned near the external bushing 4 the cooling vent temperature control point for measuring temperature 9 also is set, control and extrude the conveying effect so that regulate cooling capacity automatically through design temperature.Said inside spin carries lining 5 outer ends fixing through thread barrel positioning end 11.During work; Get into the spiral conveying mechanism of extrusion system when material after; Material is directly pushed ahead along the screw rod direction of rotation through extruder along screw conveying structure, because novel screw conveying structure and material have reduced friction and shear problem, the propelling through helical structure has improved mass transport efficient thus; Improved the plasticizing quality of material, the realization stable precision is extruded.
Above embodiment is the more preferably specific embodiment a kind of of the utility model, and common variation that those skilled in the art carry out in present technique scheme scope and replacement should be included in the protection domain of the utility model.
