Abstract
The utility model provides a conical double screw with discontinuous double thread, which is distributed by a main screw and an auxiliary screw at an included angle, and the spiral structure of double screw ridges is symmetrically distributed on the screw body, thus achieving the effects of strengthening the material intake and the mixing; the tail part of the rubber-feeding mixing section of the screw is provided with two sections of sawtooth structures, so that a better rubber-feeding effect can be achieved; the front extrusion section of the screw is changed from double screw arrises into single screw arrises (non-continuous), and the mixed rubber material can be effectively further mixed and then extruded.
Description
Technical Field
The utility model relates to a rubber and plastic machinery specifically is a toper double screw of discontinuous double thread.
Background
The screw is the core part of molding equipment such as rubber, plastics, and the screw structure in traditional double screw extruder is become the contained angle by main screw and vice screw rod and arranges, and the single screw rod is single-end screw arris and is the heliciform structure and distribute on the screw body, and the screw arris forms the screw groove on the screw body, and two screws internal rotation work to reach and eat the material, stir mixing effect, and extrude and carry to the fashioned purpose of screw front end runner mouth.
With the development of chemical industry, various novel rubber and plastic raw materials are continuously emerging, and aiming at certain special formula rubber and plastic, the feeding and mixing effects need to be enhanced in the screw feeding process. The single-head screw is ideal for material conveying, but the mixing effect is not outstanding, and the technological requirement of mixing cannot be met, so that the use or popularization of the equipment is limited.
SUMMERY OF THE UTILITY MODEL
The defect to prior art equipment, the utility model provides a toper double screw of discontinuous double thread, the toper double screw of this kind of structure can reach better glue effect of eating, effective and even extrude mixed sizing material to realize the further mixing of material.
Realize the utility model discloses the technical scheme of purpose is:
the utility model provides a toper double screw of discontinuous double thread, includes that the screw of main screw body, the mixed screw arris of main screw feed, main screw extrude the screw arris, vice screw body, the mixed screw arris of vice screw feed and vice screw extrude the screw arris, is different with prior art:
the main screw feeding and mixing screw edge is double-screw edge and is positioned in the middle section of the main screw body;
two sections of sawtooth structures are arranged at the tail part of the main screw feeding and mixing screw edge;
the main screw extrusion screw edge is a single-head screw edge and is positioned at the front section of the main screw body;
the auxiliary screw feeding and mixing screw edge is a double screw edge and is positioned in the middle section of the auxiliary screw body;
two sections of sawtooth structures are arranged at the tail part of the auxiliary screw feeding mixing screw edge;
the auxiliary screw extrusion screw edge is a single screw edge and is positioned at the front section of the auxiliary screw body;
the main screw feeding mixing screw edge, the auxiliary screw feeding mixing screw edge, the main screw extruding screw edge and the auxiliary screw extruding screw edge are in a non-continuous curve structure.
The double screws are distributed in a conical shape by the main screw and the auxiliary screw, and the spiral structures of the double screw arrises are symmetrically distributed on the screw body, so that the effect of enhancing mixing can be achieved; the rubber mixing section of the screw has two sections of sawtooth structures, so that a better rubber mixing effect can be achieved; the front extrusion section of the screw is interrupted by the double-end screw edge, and the single-end screw edge is used, so that the mixed rubber material can be effectively and uniformly extruded, and the further mixing of the materials is realized.
