Description
Technical field
This utility model relates to plastic extrusion apparatus, is specifically related to a kind of crush type plastic extrusion apparatus.
Background technology
Along with the extensive application of plastic extruder moulding process, the type of plastic extruder is increasing, and sorting technique is also
It is not quite similar.Horizontal and vertical extruder can be divided into by the locus of screw rod;Common extrusion can be divided into again by the rotating speed of screw rod
Machine, high speed and hypervelocity extruder;Divide by the quantity of screw rod, be divided into elastirotor extruder, single screw extrusion machine, twin-screw extrusion
Machine and multi-screw extruder etc., among these, the application of single screw extrusion machine is relatively broad, its work process approximately as:
After extrusion system is heated to given technological temperature held for some time, starts motor, provided by reductor
To the moment of torsion needed for screw rod and rotating speed.Plastics in hopper, under the effect of deadweight or feeder thrust, are entered spiral shell by charge door
Groove.Along with the rotation of screw rod, plastics are fed forward under the effect of frictional force between screw rod.
In forming process, material adds to plastic extruder from hopper with powdery or graininess, will complete conveying, pressure
The processes such as reality, compression, fusion plastification, the uniform melt body of chemical conversion.At screw rod feeding section, loose solid grain (or material end) is full of spiral shell
Groove, along with the continuous conveying of material, material starts to be compacted.
After material enters compression section, owing to the screw channel degree of depth gradually becomes shallower as and the resistance of head, make plastics gradually
Form high pressure, and be compacted further.Meanwhile, at barrel external heating device and screw rod with barrel inner surface to material
Strong agitation, mix and under the effect of the produced internal friction shear heat such as shearing, plastics temperature constantly raises, with barrel phase
The certain point of contact, plastics temperature arrives fusing point, starts to melt.Along with the conveying of material, continue heating, melted inventory by
Cumulative many, and non-fused mass doses reduces accordingly.About at the end of compression section, whole materials are all changed into viscous state, but
At this moment each point temperature is not yet uniform, more uniform through the homogenization just ratio of homogenizing zone.Finally, fused mass is anticipated by screw rod
It is squeezed into head amount, level pressure, constant temperature.In head of plastic extruder, mouth die is a profiled part, and material obtains one by it
Determine the cross section of geometry and size, then through cooling and shaping and other operation, so that it may obtain the goods of forming.
