Abstract
The invention discloses a kind of special-shaped pyramid type screw rod plastic extruder, including barrel, feed hopper and discharging opening are respectively equipped with the both ends of described barrel, screw rod is provided with described barrel, described screw rod is in middle thick, two sections of thin cone shapes.The present invention is by using shape in middle thick, two sections of thin conical screws, not only further increase the extrusion pressure of single-screw extruder, and the shearing force of single-screw extruder is substantially improved, the effect of crushing material fusion is improved, is improved production efficiency and product quality.
Description
Technical field
The present invention relates to a kind of special-shaped pyramid type screw rod plastic extruder.
Background technology
In known technical field, plastic extruder is a kind of conventional device of plastic processing, and screw extruder is most
A kind of conventional mixed-forming equipment, for complete plastics mixing plasticizing process, it is desirable to screw extruder have very strong shearing,
Scattered, mixed, so that the raw material of variety classes, different components being capable of smooth extrusion molding.
Have single screw extrusion machine, double screw extruder, Reciprocating Pin Twin-Screw Extruder, multiscrew in the prior art to squeeze
Go out the equipment such as machine, above-mentioned screw extruder typically has the screw rod of cylindrical form, and shearing and extruding efficiency are difficult to improve again.
The content of the invention
The technical problem to be solved in the present invention is：The plastic extruder that a kind of extrusion pressure is big, shear ability is strong is provided.
The technical solution adopted for the present invention to solve the technical problems is：Described special-shaped pyramid type screw rod plastic extrusion
Machine, including barrel, feed hopper and discharging opening are respectively equipped with the both ends of described barrel, screw rod are provided with described barrel,
Described screw rod is in middle thick, two sections of thin cone shapes.
Tilted on the madial wall of described barrel and offer at least three diversion grooves.
The quantity of described diversion groove is the six roots of sensation, and the angle of inclination of the madial wall of its diversion groove and barrel is 30 degree.
The beneficial effects of the invention are as follows：The present invention is in middle thick, two sections of thin conical screws by using shape, not only
The extrusion pressure of single-screw extruder is further increased, and substantially improves the shearing force of single-screw extruder,
The effect of crushing material fusion is improved, is improved production efficiency and product quality.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention.
Division mark is as follows in accompanying drawing：1st, barrel, 2, feed hopper, 3, discharging opening, 4, screw rod.
Embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
A kind of embodiment of special-shaped pyramid type screw rod plastic extruder of the invention as shown in Figure 1, including barrel 1, in institute
The both ends for the barrel 1 stated are respectively equipped with feed hopper 2 and discharging opening 3, and screw rod 4, described screw rod 4 are provided with described barrel 1
In middle thick, two sections of thin cone shapes, tilted on the madial wall of described barrel 1 and offer six roots of sensation diversion groove, its water conservancy diversion
The angle of inclination of groove and the madial wall of barrel 1 is 30 degree.
The embodiment of the simply present invention described in description above, various illustrations are not to the reality of the present invention
Matter Composition of contents limits, and person of an ordinary skill in the technical field can be to described in the past specific after specification has been read
Embodiment is made an amendment or deformed, without departing from the spirit and scope of invention.
