Abstract
The invention discloses a vacuum hopper of a plastic extruder. The vacuum hopper comprises a hopper body and a plurality of magnetic raised strips which are uniformly distributed on the inner wall of the hopper body and extend from the top of the hopper body to an outlet end at the bottom of the hopper body; the outlet end at the bottom of the hopper body is provided with a material blending device. By the mode, the vacuum hopper has the advantages that scrap iron in materials can be effectively adsorbed, a screw rod of a material barrel can be prevented from being clamped, the service life is prolonged, and meanwhile materials can pass smoothly and cannot be blocked easily, and materials are discharged uniformly.
Description
Technical field
The present invention relates to injection molding art, particularly relate to a kind of vacuum hopper of plastic extruder.
Background technology
Extrusion blow molding film is widely used in light industry, chemical industry, food and textile industry, is used as moistureproof, dust-proof, anticorrosion, windproof, insulation etc.
In a circulation of injection molding material machine, after the plastic heating of some being plastified in official hour, under certain pressure and speed, by screw rod, molten plastic is injected mold cavity, after injection terminates, keep sizing to the melt be expelled in die cavity, these plastics are required without least bit impurity.
And existing injection machine production raw material are by Material sucking machine inspiration feeding cylinder, there is Railway Project in this process.One, when material is more, easily blocks at the discharging opening of hopper; Its two, often can be mixed with the impurity of iron filings in the raw material of plastic cement, if this impurity is deep into screw portion, easily barrel screw rod be blocked, thus mill is fried grinds away, cause device damage.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of vacuum hopper of plastic extruder, effectively can adsorb the iron filings in material, and protection barrel screw rod is not stuck, and increases the service life; Material can be made to pass through smoothly, not easily block, discharging is even simultaneously.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the vacuum hopper providing a kind of plastic extruder, comprise: hopper body and the some magnetic raised lines be distributed in described hopper inner body wall, described magnetic raised line extends to the outlet at bottom end of described hopper body by the top of described hopper body always, and the outlet at bottom end of described hopper body is provided with material blending device.
In a preferred embodiment of the present invention, described material blending device is the stirring rod of S type.
In a preferred embodiment of the present invention, the quantity of described magnetic raised line is more than or equal to 8.
In a preferred embodiment of the present invention, described magnetic raised line comprises interior metal layer and outer magnet layer.
In a preferred embodiment of the present invention, the material of described interior metal layer is steel.
The invention has the beneficial effects as follows: by magnetic raised line uniform on the inwall of vacuum hopper, the iron filings in the material passed through are inhaled on raised line effectively, thus protection barrel screw rod is not stuck, and extends service life; And by the outlet at bottom end at vacuum hopper, agitating device is installed, material is not easily blocked through out-of-date, and discharging is even.
Accompanying drawing explanation
Fig. 1 is the structural representation in vacuum hopper one preferred embodiment of a kind of plastic extruder of the present invention;
Fig. 2 is the top view of vacuum hopper shown in Fig. 1;
In accompanying drawing, each mark is as follows: 1, hopper body, and 2, magnetic raised line, 3, material blending device.
Detailed description of the invention
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1-Fig. 2, the embodiment of the present invention comprises:
A kind of vacuum hopper of plastic extruder, comprise: hopper body 1 and the some magnetic raised lines 2 be distributed on described hopper body 1 inwall, described magnetic raised line 2 extends to the outlet at bottom end of described hopper body 1 by the top of described hopper body 1 always, and the outlet at bottom end of described hopper body 1 is provided with material blending device 3.
Described material blending device 3 is the stirring rod of S type, makes, when material is more, to obtain uniform mixing effect, avoids the phenomenon that material is blocked at the discharging opening of hopper.
The quantity of described magnetic raised line 2 is more than or equal to 8, and the distance between adjacent two magnetic raised lines 2 is (1-5) with the width ratio of magnetic raised line 2: 1, makes it reach best magnetic effect.
Described magnetic raised line 2 comprises interior metal layer and outer magnet layer; The material of described interior metal layer is steel, can retain magnetic for a long time after inner steel are magnetized, better to the adsorption effect of iron filings.
Present invention is disclosed a kind of vacuum hopper of plastic extruder, by magnetic raised line uniform on the inwall of vacuum hopper, the iron filings in the material passed through are inhaled on raised line effectively, thus protection barrel screw rod is not stuck, and extends service life; And by the outlet at bottom end at vacuum hopper, agitating device is installed, material is not easily blocked through out-of-date, and discharging is even.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and Figure of description content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
