Abstract
The invention discloses a kind of dedicated flow distribution plates of semiconductive power cable material extruder, and including plate body and several eyelets being arranged on plate body, the diameter of the eyelet at plate body center is greater than the diameter of the eyelet on plate body periphery.The present invention has the characteristics that design is reasonable, easy to use, and can not only being discharged using it, uniform, gel quantity is big, and it is high to squeeze out quality.
Description
Technical field
The present invention relates to the components of extruder, and in particular to a kind of dedicated flow distribution plate of semiconductive power cable material extruder.
Background technique
Semiconductive cable material of polyolefin is used for the conductor shielding (inner shield) and insulation shielding of 10kV or more power cable
(external shield) prevents shelf depreciation with field distribution in homogeneous insulation layers.Since a large amount of conductive charcoals being added in material polyethylene
After black, raw material is hardened, and mobility is deteriorated, and performance becomes fragile, and squeezes out highly difficult.Currently, manufacturer in order to adapt to squeeze out work
Skill and meet necessary mechanical and physical character, will several eyelets be set on flow distribution plate, make every effort to promote material uniformly through.But due to
Pressure of the pressure of screw head material close to top center is small, and screw rod excircle site pressure is maximum, tradition on flow distribution plate
Eye diameter it is identical, have the following disadvantages: 1, because material viscosity is big, poor fluidity easily causes flow distribution plate centre stream
Obstructed, the residence time is too long and causes thermal decomposition；2, gel quantity is few, and host electric current is big, has the pimple of incipient scorch to produce often
Raw, extrusion pin is of poor quality.
Summary of the invention
The object of the present invention is to provide a kind of dischargings uniformly, gel quantity is big, squeezes out the high semiconductive power cable material of quality squeezes
The dedicated flow distribution plate of machine out.
In order to achieve the above objectives, a kind of dedicated flow distribution plate of semiconductive power cable material extruder of the present invention, including plate body, plate
Several eyelets are provided at body center and on periphery, the diameter of the eyelet at plate body center is greater than the straight of the eyelet on plate body periphery
Diameter.
By adopting the above-described technical solution, several eyelets are provided on plate body of the invention, the eyelet at plate body center
Diameter be greater than plate body periphery eyelet diameter.Because pressure of the pressure of screw head material close to top center is small, and
Screw rod excircle site pressure is maximum, adopts the structure, so that material flow velocity in the cross section of plate body is consistent, improves object
The mobility of material discharges uniform, smooth so that material be made to be not easy thermal decomposition, improves extrusion output.
Detailed description of the invention
Fig. 1 is the dedicated manifold structure schematic diagram of semiconductive power cable material extruder of the present invention；
Fig. 2 is the cross-sectional view of plate body of the invention.
Specific embodiment
The dedicated flow distribution plate of semiconductive power cable material extruder of the present invention is described further with reference to the accompanying drawing
By Fig. 1, Fig. 2 as it can be seen that the dedicated flow distribution plate of semiconductive power cable material extruder of the present invention, including plate body 1 and setting exist
Several eyelets 2 on plate body, the diameter of the eyelet at 1 center of plate body are greater than the diameter of the eyelet on plate body periphery.
The diameter of eyelet at 1 center of plate body of the invention is greater than the diameter of the eyelet on plate body periphery.Because of screw head
Pressure of the pressure of portion's material close to top center is small, and screw rod excircle site pressure is maximum, adopts the structure, so that object
Material flow velocity in the cross section of plate body 1 is consistent, the mobility of material is improved, to make material be not easy thermal decomposition, out
Expect uniform, smooth, raising extrusion output.
