Fig. 1 is operation principle schematic diagram of the present invention.
Fig. 2 is another embodiment of the present invention schematic diagram.
Each label meaning is in figure：1. extruder mouth, 2. first heater strips, 3. fixed plates, 4. second heater strips, 5.
Three heater strips, 6. heated walls.
Embodiment
With reference to the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Ground describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.Based on this hair
Embodiment in bright, those of ordinary skill in the art are not under the premise of creative work is made, the every other reality that is obtained
Example is applied, belongs to the scope of the present invention.
Referring to accompanying drawing 1, a kind of stereoscopic heating type plastic extrusion machine head of the invention includes extruder mouth 1, and extruder mouth 1 is in
Round table-like and feeding end is arranged at the radius maximum side of extruder mouth 1, exhaust end is arranged at the radius minimum one of extruder mouth 1
Side, the inwall of extruder mouth 1 is wound with the first heater strip 2 successively along the generatrix direction of extruder mouth 1 and the first heater strip 2 is being extruded
It is distributed on any one generatrix direction of the inwall of machine mouth 1 in uniform intervals；During work, ginseng has the molten state polyphenyl second of solid granulates
Alkene by feeding end enter extruder mouth 1 inner chamber, now the first heater strip 2 by convection heat transfer' heat-transfer by convection to by the feeding end of extruder mouth 1
The molten state polystyrene that flowing to the ginseng of the exhaust end of extruder mouth 1 has solid granulates is heated, because the first heater strip 2 is in circle
Interval is provided with arcuation and the generatrix direction of extruder mouth 1, therefore effective heating surface (area) (HS of the first heater strip 2 is the first heating
2 surface area on the inwall stroke of extruder mouth 1 of silk, increases the molten state polyphenyl second that effective heating surface (area) (HS makes ginseng have solid granulates
Heat exchange amount of the alkene in the stroke of extruder mouth 1 increases and improves the first heater strip 2 to its rate of heat addition, has effectively melted and has mixed
In the solid-state granules of polystyrene of molten state polystyrene, the first heater strip 2 is arranged at the inwall of extruder mouth 1 and in polyphenyl
Ethene directly contacts, and which makes the first heater strip 2 directly be contacted with polystyrene, and it, which has, reduces thermal contact resistance, improves and change
The advantages of thermal efficiency, because the characteristic size of the first heater strip 2 is much smaller than the characteristic size of extruder mouth 1, therefore the first heating
The flowing interference of 2 pairs of molten state polystyrene of silk is negligible, ensure that extruder mouth 1 extrudes the steady of molten state polystyrene
It is qualitative.
As another embodiment of this programme, referring to accompanying drawing 2, the feeding end of described extruder mouth 1 is provided with fixed plate
3, it is in 90 degree that fixed plate 3, which includes some circumferentially arranged transverse slats and adjacent transverse slat, and fixed plate lower end is connected with frustum
Heated wall 6 and heated wall 6 bus is parallel with the bus of extruder mouth 1, center line of heated wall 6 and extruder mouth 1
Centerline collineation, the generatrix direction of the outer wall of heated wall 6 is wound with the 3rd heater strip 5 successively and the 3rd heater strip 5 is in heated wall 6
It is distributed on any one generatrix direction of outer wall in uniform intervals, the generatrix direction of the inwall of heated wall 6 is wound with second and added successively
Heated filament 4 and the second heater strip 4 are in that uniform intervals are distributed on any one generatrix direction of the inwall of heated wall 6；During work, ginseng
The molten state polystyrene for having solid granulates enters the inner chamber of extruder mouth 1, and now the first heater strip 2 is pointed to heated wall 6 with squeezing
Polystyrene between machine outlet 1 pointed to along the circumference of extruder mouth 1 heating of the centerline direction of extruder mouth 1, and the 3rd adds
The polystyrene that heated filament is pointed between heated wall 6 and extruder mouth 1 carries out pointing to extruder mouth 1 along the center line of extruder mouth 1
The heating of circumferencial direction, the polystyrene that the second heater strip 4 is pointed to the inner chamber of heated wall 6 add along the sensing of the inwall of heated wall 6
The heating of the centerline direction of hot wall 6, the heating for having the polystyrene progress different azimuth of solid granulates to ginseng make polystyrene exist
Temperature rise rate in extruder mouth 1 is faster, heat exchange is stronger and polystyrene solid granulates is melted completely in extruder mouth 1
Change.
