As this kind of preferred scheme, the upper helical blade of described extrusion screw rod extends to reduced pressure sealing cylinder front end face place.
As this kind of preferred scheme, the setting position of described discharging opening is near reduced pressure sealing cylinder front end face.
As this kind of preferred scheme, described discharging opening is circumferentially evenly arranged at stack shell, and distributes ringwise, and the opening's edge of the most downstream of discharging opening is concordant with reduced pressure sealing cylinder front end face.
As this kind of preferred scheme, described sealed bearing also offers the circulating cooling passage for lowering the temperature to this bearing block.
As this kind of preferred scheme, described grain-cutter comprises tool rest plate, some axial knife bars and the blade supporting with knife bar, described knife bar is installed on tool rest plate, and tool rest plate is connected with grain-cutter power set, and described blade is installed on knife bar and with the outer wall of extruded tube and coordinates.
As this kind of preferred scheme, the outer wall of described blade and extruded tube rotates downstream and acutangulates.
After have employed technique scheme, the invention has the beneficial effects as follows: because a kind of plastics recovery of the application discharging opening extracting pre-pelleter is arranged at the stack shell tract extracting cylinder, discharging opening is positioned at the upstream of bearing block, but not be arranged on sealed bearing, reduce the extruding force of material to sealed bearing, discharging opening is not located on sealed bearing, the temperature of sealed bearing and bearing also significantly reduces, avoid lubricating oil Yin Gaowen and go bad, cause bearing damage, optical axis portion and reduced pressure sealing cylinder matched in clearance, material is not easy to enter in reduced pressure sealing cylinder by gap, more difficultly enter in sealed bearing, ensure that this extracts the normal operation of pre-pelleter, and the discharging opening of this pre-pelleter be arranged at extract cylinder stack shell circumferentially, bearing block is arranged at before comparing, the length of discharging opening obviously shortens, the probability that discharging opening blocks because of sclerosis also reduces greatly, in sum, the application's plastics recovery is high with extracting pre-pelleter operating efficiency, long service life.
Again because the upper helical blade of described extrusion screw rod extends to reduced pressure sealing cylinder front end face place, farthest can extrude material, what hardened to discharge outlet plays fragmentation simultaneously, facilitates discharging.
Again because the setting position of described discharging opening is near reduced pressure sealing cylinder front end face, so material be subject to reduced pressure sealing cylinder front end face stop afterwards direct from.
Again because described discharging opening is evenly arranged on stack shell, and distribute ringwise, and the opening's edge of the most downstream of discharging opening being concordant with reduced pressure sealing cylinder front end face, when extracting material to greatest extent, realizing timely discharging.
Again owing to described sealed bearing also offering for the circulating cooling passage of this bearing block cooling, when the temperature of bearing block and bearing is too high, recirculated cooling water can be passed in time and it is lowered the temperature.
Again because described grain-cutter comprises tool rest plate, some axial knife bars and the blade supporting with knife bar, described knife bar is installed on tool rest plate, tool rest plate is connected with grain-cutter power set, described blade is installed on knife bar and with the outer wall of extruded tube and coordinates, multiple blade blank simultaneously can be realized, control particle size, make blank more timely, quick.
Acutangulate because the outer wall of described blade and extruded tube rotates downstream again, can ensure that blank is relatively more thorough, damage can not be caused to the outer wall of extruded tube again.
