Abstract
The utility model discloses a kind of screw rod, comprise feeding section, fluxing zone and metering section, described screw rod is bipyramid shape, described feeding section, fluxing zone and metering section have all attacked screw thread, screw thread on screw rod is made up of different pitch segmentation, increase between described fluxing zone and metering section and have mixing section, described metering section cross-sectional area is less compared to fluxing zone, and described fluxing zone cross-sectional area is less compared to feeding section.This screw rod can reach conveying better, compacting, mixing and plasticizing, and realizes exhaust, the objects such as dehydration.
Description
technical field:
The utility model relates to production and processing field, safer more specifically to one, more efficiency, more energy-conservation screw of plastic extruder.
background technology:
Screw rod completes the conveying of plastics and the vital part of plasticizing in plastic extruder, when rotating in machine barrel, powdered plastic is plastified pusher to head, thus reach compacting, melting, the object of mixing homogenizing, but traditional extruder screw mass transport and plasticizing capacity more weak, its exhaust effect is not good simultaneously, plastics are subject to larger restriction in extrusion, and traditional screw rod is not equipped with corresponding screw rod register, not only reduce quality and the output of goods, also reduce the service life of screw rod, problem to be solved in the utility model that Here it is.
utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and a kind of practical screw rod is provided, its structure is bipyramid shape, its feature makes feeding section have larger diameter and charging space, to material heat transfer area relatively with shear rate to increase, be conducive to the plasticizing of material, metering section screw diameter is little, decrease heat transfer area and the shear rate to melt, melt can be extruded at a lower temperature, screw rod adopts screw core register, improve the Quality and yield of goods, screw thread on screw rod is made up of different pitch segmentation, it is less that metering section diameter compares fluxing zone diameter, it is less that fluxing zone diameter compares feeding section.
Technology solution of the present utility model is as follows:
A kind of screw rod, it comprises the feeding section, fluxing zone and the metering section that are linked in sequence successively, and described feeding section, fluxing zone and metering section have all attacked screw thread, and screw thread is made up of coarse pitch and fine pitch segmentation.
Increase between described fluxing zone and metering section and have mixing section.
Described metering section cross-sectional area is less compared to fluxing zone, and described fluxing zone cross-sectional area is less compared to feeding section.
Described screw rod is bipyramid shape.
The beneficial effects of the utility model are:
1, screw rod is bipyramid shape, and its feature makes feeding section have larger diameter and charging space, to material heat transfer area relatively with shear rate to increase, be conducive to the plasticizing of material.
2, metering section screw diameter is little, decreases heat transfer area and the shear rate to melt, and melt can be extruded at a lower temperature.
3, screw rod adopts screw core register, and the conduction oil through outer circulation carrys out adjusting screw(rod) temperature, thus improves the Quality and yield of goods.
4, the screw thread on screw rod is made up of to reach better conveying, compacting, mixing and plasticizing different pitch segmentation, and realizes exhaust, dehydration object.
5, because screw rod is tapered, small end is metering section, and cross-sectional area is little, and axial force is less, otherwise space, large end place is large, can install and bear the bearing of larger axis to load forces.
accompanying drawing illustrates:
Fig. 1 is schematic perspective view of the present utility model;
In figure: A, feeding section; B, fluxing zone; C, metering section; D, mixing section; L1, coarse pitch; L2, fine pitch.
detailed description of the invention:
Embodiment: as shown in Figure 1, screw rod is bipyramid shape, it comprises the feeding section (A), fluxing zone (B) and the metering section (C) that are linked in sequence successively, described feeding section (A), fluxing zone (B) and metering section (C) have all attacked screw thread, and described screw thread is made up of coarse pitch (L1) and fine pitch (L2) segmentation.Increase between fluxing zone (B) and metering section (C) and have mixing section (D), metering section (C) cross-sectional area is less compared to fluxing zone (B), and fluxing zone (B) cross-sectional area is less compared to feeding section (A).
Claims (1)
1. a screw rod, it is characterized in that: comprise the feeding section (A) be linked in sequence successively, fluxing zone (B) and metering section (C), described feeding section (A), fluxing zone (B) and metering section (C) have all attacked screw thread, described screw thread is made up of coarse pitch (L1) and fine pitch (L2) segmentation, mixing section (D) is installed between described fluxing zone (B) and metering section (C), described metering section (C) cross-sectional area is less compared to fluxing zone (B), described fluxing zone (B) cross-sectional area is less compared to feeding section (A), described screw rod is bipyramid shape.
