Description
Technical field
The present invention relates to composite material production equipment field, especially a kind of special extrusion equipment of PP composite material.
Background technology
In the prior art, all it is to heat plastic raw materials using common extruder to squeeze out during for plastics-production
At material strip, material strip is recycled to be cut granulation.But existing extruder has certain pressure in extrusion, so
Material strip after extrusion will produce certain expansion, and the diameter of material strip is caused to increase, and can influence the cooling of material strip and last granulation
Grain size when molding.
Invention content
The purpose of the present invention is to solve the deficiencies of the above technologies and provide a kind of can effectively ensure material after extrusion
Diameter can be maintained at setting value, and the special extrusion equipment of PP composite material that performance is stablized.
In order to achieve the above object, the special extrusion equipment of a kind of PP composite material designed by the present invention, including squeeze
The extrusion screw rod for going out owner's body and extruded tube and being arranged inside extruded tube, extrusion screw rod is connect with extruder main body, close
It is provided with feed inlet in the extruded tube of extruder main body one end, has extrusion die in the end set of extruded tube；The extrusion
Mold includes the connector being connect with extruded tube end, and connector is internally provided with the hollow structure of cylindrical shape, hollow
No.1 template, No. two templates and No. three templates are provided in structure, the equal array in No.1 template, No. two templates, No. three templates
There are several through-holes, and the position of the through-hole in each template corresponds, No.1 template, No. two templates, No. three template three patches
It closes and is arranged inside connector, wherein No.1 template, the identical cylinder through-hole of the equal diameter of through-hole in No. three templates, No. two moulds
The diameter of through-hole is gradually reduced from both ends to centre on plate, and the maximum gauge of the through-hole in No. two templates and No.1 template, three
Through-hole diameter in number template is identical, and the minimum diameter of the through-hole in No. two templates is No.1 template, through-hole is straight in No. three templates
The 90-95% of diameter.
Above-mentioned technical proposal, in use, extrusion screw rod will discharge after material extruding from extrusion die, according to extrusion
Through-hole on mold forms material strip and is cooled down；And when raw material is pressed into the through-hole in No.1 template, it is substantially straight to it
Diameter is defined, and then through-hole diameter reduces in No. two templates of entrance, No. two templates, material strip diameter is gradually reduced, then
The through-hole of No. three templates is entered back into, and the through-hole diameter in No. three templates is slightly larger than the through-hole diameter of No. two templates, expects here
Item release internal pressure increases its diameter, is finally quantified in the through-hole in No. three templates, it is ensured that material strip after extrusion
Diameter keep constant, and be the diameter of through-hole in No. three templates；It is more convenient for the control to material strip diameter so that discharging is whole
Together, reliably, stability is high.
No.1 template, No. two templates, the length ratio of through-hole is 2 in No. three templates：1：4.The design of the structure can be convenient for material
The sizing of diameter.
The connector end being connect with extruded tube is to being inclined cambered surface transition between No.1 template.The design of the structure,
Avoid the generation at dead angle so that the raw material in extruded tube is in recurrent state.
There is gap between No.1 template, No. two templates, the projection of the through-hole in No. three templates on the horizontal level.It should
Situations such as design of structure, it will not overlap when material strip after extrusion hangs down into bosh, avoids between material strip
It interferes and influences quality.
A kind of obtained special extrusion equipment of PP composite material of the present invention can have by rational structure design
The realization of effect carries out accurate control to the diameter of the material strip of extrusion, and stability is high, and the consistency of product is good.
