Abstract
The utility model discloses a screw rod, which comprises a rod body, wherein the rod body consists of a feeding section, a melting section, a homogenizing section and an extruding section; and the melting section and the extruding section are provided with screw ridges respectively. The screw rod is characterized in that: the homogenizing section is provided with discontinuous screw ridges which are distributed uniformly; and the discontinuous screw ridges are matched with a screw in a screw rod barrel. Compared with the prior art, the screw rod has the advantages: the homogenizing section of the screw rod is provided with discontinuous screw ridges which are distributed uniformly, and the discontinuous screw ridges are matched with the screw in the screw rod barrel, so that shearing of molten materials is facilitated, material stagnation period is shortened, decomposition of materials is reduced, production efficiency and plasticizing efficiency are increased, materials can be heated uniformly during melting, materials are prevented from being burnt out easily, and a better working effect is achieved.
Description
Technical field
The utility model relates to the extruder manufacture technology field, especially relates to a kind of screw rod.
Background technology
Screw rod is one of kernel component of extrusion equipment; Main effect is with solid-state plastic cement particle or powder, through carrying steps such as compacting, compression fusion, homogenizing metering, converts the plastic cement melt of stable uniform to; Export to die head and subsidiary engine equipment, produce satisfactory product.
Existing a kind of application number is called the Chinese utility model patent of " a kind of spinning screw " for the CN201020686340.1 name; A kind of spinning screw is disclosed; Form by feeding section (A), melt zone (B), homogenizing zone (C), mixing extruding zone (E) successively; Feeding section (A), melt zone (B), homogenizing zone (C) are provided with spiral shell rib (1); It is characterized in that: said screw rod long (L) is in a ratio of L: D=29 with the diameter (D) of spiral shell rib (1): 1; Be distributed with columned protruding nail (2) on the periphery of said mixing extruding zone (E), its advantage of the utility model is: at feeding section: make material carry out preheating, compacting and conveying, make material be converted into liquid from solid reposefully and get ready; And at melt zone: make further compacting of material and plasticizing, make material be converted into liquid condition from solid equably, this section is solid and the liquid and the section of depositing.Homogenizing zone: can make material further plasticizing and homogenising: realize quantitatively at mixing extruding zone, level pressure, constant temperature ground is extruded from head.But the structure of this screw rod makes material long dead time, thereby it is unhappy that material is sheared, so plasticizing efficiency is not high, and the structure of this screw rod that material is heated is inhomogeneous, so the structure of this screw rod needs further improvement.
Summary of the invention
The utility model technical problem to be solved is to provide a kind of material to shear soon, be heated evenly and the high screw rod of plasticizing efficiency to above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this screw rod; Include the body of rod; This body of rod is made up of feeding section, melt zone, homogenizing zone, extruding zone successively; On said melt zone and extruding zone, be respectively arranged with the spiral shell rib, it is characterized in that: said homogenizing zone is provided with the equally distributed disconnected spiral shell rib of disconnection, and the screw of said disconnected spiral shell rib in spiro rod machine tube fits in.
As improvement, said disconnected spiral shell rib is 4 °～6 ° with the angle between the vertical vertical line in top in first sideline of axial section and this first sideline.
Improve, said disconnected spiral shell rib is 14 °～16 ° with the angle between the vertical vertical line in top in second sideline of axial section and this second sideline again.
Improve, said disconnected spiral shell rib is 9～11mm with the corner radius of the radian on the edge line both sides of axial section again.
Improve, the extruding end of said extruding zone is that tapering is 89 °～93 ° a conical head again.
Compared with prior art, the advantage of the utility model is that this screw rod homogenizing zone is provided with the equally distributed disconnected spiral shell rib of disconnection, and the disconnected spiral shell rib of this screw rod and the screw in the spiro rod machine tube are suitable; This structure helps the shearing of fused materials, reduces material dead time, thereby has reduced the decomposition of material; Therefore production efficiency and plasticizing efficiency have been improved; And this structure can make material when fusion, be heated evenly, so material is difficult for burning, and its work is better.
