Compared with the prior art, the utility model has the advantages of structural shapes design through improving the screw rod makes the quality of its plastic products that make get a promotion to plate the nickel coating on screw rod whole surface, improved extrusion molding screw rod's wearability, improved extrusion molding screw rod's life.
Description
Technical field
This utility model is related to a kind of extruding machine manufacture technology field, especially a kind of extrusion screw.
Background technology
Screw rod is the requisite critical component of plastic extruder, its effect be plastics are conveyed, are compacted,
Fusing, stirring and pressure.All these is all to rotate to complete in barrel by screw rod.When screw rod rotates, plastics
Tackle and occur between machine tube inner wall, screw channel bottom surface, spiral shell rib pressure surface and plastics and plastics strong friction and interaction.
Plastics push ahead be this movable composition result, and rub occur heat also the plastics temperature that improves is used for by absorption
And fusing plastics.In plasticizing process in extruder, it improves plastics and the power that is mingled with all is derived from screw rod and barrel
Rotate against.Distributional pattern according to plastics in screw channel, is typically divided into three sections screw rod：Solid conveying section (is also named and added
Material section), melt zone (also crying compression section), homogenizing zone (also referred to as metering section).The structure design layout of screw rod will directly influence this
The level of a little effects.Extrusion plus man-hour are carried out using the single screw extrusion machine without degassing function, is often occurred following
Problem：1st, melt mixed is not uniform enough, so that obtained plastic fisheye and bubble are more；2nd, in order to realize preferably plasticizing
Effect, it is desirable to which screw rod has larger compression ratio, it is larger that this can cause plastics materials temperature to raise, so that the plastics materials of extrusion
Viscosity is low, affects the quality of obtained plastic；3rd, high energy consumption in extrusion process, it is wear-resisting due to screw surface material
Property it is poor cause that screw rod abrasion is very fast, the service life of screw rod is shorter.So its structure also needs to improve.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of extrusion screw for above-mentioned state of the art,
The quality for making its obtained plastic gets a promotion, and improves the wearability of screw rod, to improve its service life.
This utility model solve the technical scheme that adopted of above-mentioned technical problem for：This kind of extrusion screw, including roofbolt with
Used as the conical head of extruding end, the roofbolt is in turn divided into power input section, solid conveying section, is melted by effect during its work
Melt section, homogenizing zone, power input section arranges keyway, it is characterised in that the solid conveying section, melt zone, homogenizing zone are along roofbolt
Surface arranges continuous main spiral shell rib, and the pitch of the main spiral shell rib, rib width and the high constant of rib are constant, and the screw rod integral surface is coated with
Nickel coating.
Used as improvement, solid conveying section and the melt zone of the roofbolt can only arrange single described main spiral shell rib；The bar
The homogenizing zone of post then includes main spiral shell rib, and with the secondary spiral shell rib for deriving from and coming from the main spiral shell rib, the spiral shell rib external diameter of the secondary spiral shell rib is less than master
The spiral shell rib external diameter of spiral shell rib, the rib width of the rib width of the secondary spiral shell rib again smaller than main spiral shell rib.
Used as improvement, the roofbolt also includes the changeover portion being arranged between power input section and solid conveying section.
Improve again, the conical head preferably opens up 4 grooves along its circumference, and along its circumference uniform distribution.
Compared with prior art, the utility model has the advantage of the planform design by improving screw rod so as to make
The quality of the plastic for obtaining gets a promotion, and is coated with nickel coating in screw rod integral surface, improves the wearability of extrusion screw,
Improve the service life of extrusion screw.

Specific embodiment
This utility model is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in Figures 1 to 7, the extrusion screw of the present embodiment be example extrusion screw, including roofbolt 1 with as extruding end
Conical head 2, roofbolt 1 is in turn divided into power input section 3, solid conveying section 4, melt zone 5, homogenizing by effect during its work
Section 6, power input section 3 arranges keyway 7, and solid conveying section 4, melt zone 5, homogenizing zone 6 arrange continuous main spiral shell along the surface of roofbolt 1
Rib 8, the high constant of the pitch of the main spiral shell rib 8, rib width and rib is constant, and screw rod integral surface is coated with nickel coating.The solid of roofbolt 1 is defeated
Send section 4 that single main spiral shell rib 8 is only set with melt zone 5；The homogenizing zone 6 of roofbolt 1 then includes main spiral shell rib 8, and from the main group of spiral shell rib 8
The secondary spiral shell rib 9 given birth to and come, the spiral shell rib external diameter of the secondary spiral shell rib 9 is less than the spiral shell rib external diameter of main spiral shell rib 8, and the rib width of the secondary spiral shell rib 9 is also little
In the rib width of main spiral shell rib 8.Roofbolt 1 also includes the changeover portion 10 being arranged between power input section 3 and solid conveying section 4.Taper
2 open up 4 grooves 11 along its circumference, and along its circumference uniform distribution.The structure that this utility model extrusion screw passes through improvement screw rod
Shape is designed so as to which the quality of obtained plastic gets a promotion, and is coated with nickel coating in screw rod integral surface, improves crowded
The wearability of modeling screw rod, improves the service life of extrusion screw.
