Description
Technical field：
The present invention relates to a kind of screw extruders, belong to plastic material production equipment technology.
Background technology：
Plastic granulating is a kind of technique of plastics machinery processing, exactly the plastics of various different shapes by melting, squeezing out, cut
The processes such as grain are prepared into graininess that facilitate following process, uniform.Screw extruder is the core equipment of plastic granulating, according to
The pressure and shearing force generated by screw rod rotation, can allow material fully to carry out plasticizing and uniformly mixing, pass through mouth mold
Molding.Therefore, screw extruder is during plastic granulating, the general mixing that carry material simultaneously, and heating mixing squeezes out
Work can influence whole product quality if one of Absent measures are bad.Existing screw extruder uses straight tube
Structure, screw rod complete stirring, mixing process after, bubble is contained in material, directly extrudes cooling and dicing, causes product matter
It measures poor.
Invention content
The purpose of the present invention is providing a kind of screw extruder in view of the above problems, avoid containing in the product squeezed out
There is bubble, improves the quality of material grain.
Above-mentioned purpose is achieved through the following technical solutions：
A kind of screw extruder, including body, the body are divided into batch mixing segment, heating melt zone and heat preservation extruding zone,
The batch mixing segment and the heating melt zone are horizontally disposed, and the heat preservation extruding zone is with the heating melt zone at downward 45° angle
It is obliquely installed, the internal body is provided with the first screw rod being horizontally mounted, and the end of first screw rod is located at described add
The junction of heat fusing section and the heat preservation extruding zone is equipped with spiral bevel gear, and the spiral bevel gear is nibbled with helical gear
It closes, helical gear connection is located at the second screw rod in the heat preservation extruding zone.
The screw extruder is provided with feed inlet on the batch mixing segment.
The screw extruder is provided with electric heater unit on the heating melt zone.
The screw extruder, the heat preservation extruding zone are provided with insulating layer.
The screw extruder is provided with stirrer gear on first screw rod.
The junction of the screw extruder, the heating melt zone and the heat preservation extruding zone is provided with exhaust
Mouthful.
Advantageous effect：
The present invention is arranged diagonally downward by extruding zone is kept the temperature, after material arrival heat preservation extruding zone under the action of gravity and screw rod
It trickles diagonally downward, is conducive to the bubble for excluding to mix in material, the material granule density squeezed out in this way is uniform, and material grain quality is high.
