Screw extruder.Screw extruder mainly includes the structures such as motor, screw rod, heater and cooling device, wherein heating dress
It is that screw rod is heated using cast aluminium heating collar, ceramic electric heating circle to put mostly, and existing heating means are all in extruder
Casing sets the modes such as heat block, heater strip, but the heating-up temperature of the mode of heating is uneven, and temperature is difficult to control to, surely
Determine that effect is bad, and then the quality of extruded product can be influenceed, reduce production efficiency, or even cause certain economic loss.In addition,
Charging inequality can also reduce the efficiency of extrusion molding, and part material can be sticked on the casing of charging aperture, cause raw material to mould
Change etc. is not exclusively.
It is uniform that the uniform injecting mechanism (Application No. 201420191548.4) of patent one kind plasticizing discloses a kind of plasticizing
Injecting mechanism, by being provided with heating coil in the outer surface of heating chamber, the heating coil is connected with external heater,
So as to realize the heating to raw material, the hybrid activity of melt liquid can be increased by increasing mixing component.But the practicality is new
Type is only heated from device, and heating is uneven, and mixing component is only capable of increasing the uniformity of melt liquid, and is fed and be just difficult to
It is well mixed.
Therefore be badly in need of provide one kind can effectively disperse charging aperture raw material, prevent from retaining raw material on box body wall, with from add
Hot merit energy, a kind of uniform and stable extruder screw of heating effect.
Utility model content
The purpose of this utility model is can effectively to disperse charging aperture there is provided one kind for the not enough of existing extruder screw

Body is hollow structure, and heat conductive rod is provided with the middle cavity of the screw body, and the heat conductive rod is led including linear first
Hot pin and using first heat conductive rod as the second heat conductive rod of axle spiral winding, second heat conductive rod is provided with heat transmission fin, institute
State the outer surface in the middle part of screw body and temperature sensor is installed.
It is preferred that, the quantity of the stirring vane is 2-3, and the stirring vane is formed in one with the screw body
Or be welded and fixed, the stirring vane can effectively disperse the raw material from extruding machine inlet, while ensureing extrusion cabinet
Internal surface is adhered to without raw material accumulates.
It is preferred that, first heat conductive rod and second heat conductive rod are integrally formed, the heat conductive rod and heater phase
Even, the design makes screw rod realize heating.
It is preferred that, the surface of the screw body, the spiral shell rib and the stirring vane is covered with one layer of wear-resistant coating, and this is resistance to
Mill coating can extend the service life of screw rod.
The beneficial effects of the utility model are：
(1) the utility model stirring vane is designed to the effective scattered raw material from extruding machine inlet, simultaneously
Ensure that interior is adhered to without raw material to accumulate, improve extrusion forming efficiency.
(2) the utility model installs heat conductive rod in the middle cavity of screw body, and heat conductive rod is connected with heater, heat conduction
Rod is provided with heat transmission fin, can increase the conduction surface of heat, and this is designed to directly heat screw rod, improves the techniques such as plasticizing
Efficiency, the efficiency of heating surface is high.
(3) surface of screw body, spiral shell rib and stirring vane is covered with one layer of wear-resistant coating, and the wear-resistant coating can strengthen spiral shell
The anti-wear performance of bar, prevents for a long time using there is fluid stream leakage phenomenon, extends the service life of screw rod.
