Description
Technical field
The invention belongs to technical field of plastic.
Background technique
Plastics kneader is a kind of stirring mixer, it is mainly by mixing chamber and a pair of stirring knife group rotated in mutually opposite directions
At having that mixing efficiency is high, mixed material is uniform, easy to operate and be easy to clean for mixing the plastic substance of high and low viscosity
The features such as.Common kneader from top to bottom successively includes lid, inner cylinder, and the inner cavity of inner cylinder is mixing chamber, the bottom of mixing chamber
It is interior to be arranged side by side that (speed of two stirring knifes is different, avoid the formation of symmetrical cycle and reduce engagement effect there are two stirring knife
Fruit), when work, two stirring knifes are rotated backward, so that plastics materials are stirred along the side wall of mixing chamber, plastics materials enter back into two
Gap between stirring knife top surface and mixing chamber roof, and being fallen (between two stirring knifes) from and among mixing chamber, material to by
To kneading and kneading effect repeatedly, reach mixed uniformly purpose.The cell wall of mixing chamber has collet, can be passed through steaming in collet
Vapour and cooling water are heated so that mixing indoor material and waste water are precipitated after cooling down.
The shortcomings that above-mentioned kneader, is：1, what is relied solely on is the kneading of stirring blade so that material is squeezed, still
Material at the dead angle of mixing chamber can not be rubbed pressure, eventually lead to the ineffective of plastics kneading；2, the thickness of stirring knife is certain,
Gap size among mixing chamber be also it is certain, can not be adjusted according to inventory (i.e. kneading amount), when by gap
When material is less, material is not contacted with mixing chamber roof, and material after the extruding force of side plate by falling between two stirring knifes, also
It is not to be squeezed on saying material here vertically, that finally mediates is ineffective；3, the bleed generated in mixing chamber, is being pinched
Closing can still stay in mixing chamber before completing, and such material can absorb part bleed, the minimum plastics combined amount come out again
Water content it is excessively high.
Summary of the invention
The invention is intended to provide a kind of plastics kneader that can carry out rubbing pressure and stirring knife variable thickness to material at dead angle.
A kind of plastics kneader, including firm banking are placed with overhead guard on the firm banking, which is in cylindrical structure
And opening is downward, and pressing plate is hinged on overhead guard side wall, firm banking is equipped with flow surface obliquely in the periphery of overhead guard；Fixed bottom
Seat lower section is provided with intermeshing driving gear, driven gear, and active transmission cylinder is vertically equipped on the firm banking, described
Active transmission cylinder runs through overhead guard, and active transmission cylinder is connect with overhead guard eccentric position flat key, and active transmission cylinder upper end is circumscribed with air pump,
The lower end of active transmission cylinder is connect with driving gear spline；Be provided with through hole on the firm banking, be equipped in firm banking with
The air flue that through hole communicates, the external above-mentioned air pump of the air flue, through hole is inserted with slave drive cylinder, slave drive cylinder and air flue phase
Pair position on be provided with air inlet；The active transmission cylinder is located at flat key on the shell portion of overhead guard inner cavity and is connected with active stirring knife, from
The upper end of dynamic transmission cylinder is protruded into overhead guard inner cavity but is not connect with overhead guard, and driven stirring knife is connected on the dip section of slave drive cylinder,
The lower end of slave drive cylinder is connect with driven gear spline；The active stirring knife, driven stirring from top to bottom include that sliding is matched
The cutter hub and knife lid of conjunction, knife lid are inverted U shape, and form knife chamber between knife lid and cutter hub, active transmission cylinder and slave drive cylinder with
Be provided with several ventholes on the corresponding stack shell of knife chamber, at each venthole outside be cased with the air bag of annular, the air inlet of the air bag with
Vent seal connection；The cross section of the active stirring knife and driven stirring knife is ellipse.
Beneficial effect：Overhead guard is to fasten downward on the fixed base in the present invention, and the inner cavity of overhead guard is mixing chamber, fixed
Pedestal is equipped with flow surface obliquely in the periphery of overhead guard, so that the bleed that material is generated when rubbing pressure is flowed out of overhead guard
Out, and along flow surface it excludes, avoids the problem of traditional plastics kneader bleed can be trapped in mixing chamber in this way；Actively
Stirring knife, driven stirring knife are driven by active transmission cylinder, slave drive cylinder respectively to be carried out plastics and rubs pressure, and at this time overhead guard also in master
Eccentric rotary under the drive of dynamic transmission cylinder, so that material is not only rubbed pressure, but also the extruding by overhead guard by stirring knife plate, in this way
Inside and outside " pincer attack " allow for the material at mixing chamber dead angle and inevitably rubbed pressure, and pressure is hinged on overhead guard side wall
Plate, pressing plate can also be rotated with overhead guard, and pressing plate is different in the stress of different location, but also pressing plate, which is swung, carries out pressing materials,
Design in this way, so that the material at mixing chamber dead angle is also kneaded；The knife of stirring knife (active stirring knife, passive stirring knife) is intracavitary
Design has several air bags, and air pump is inflated into transmission cylinder (active transmission cylinder, slave drive cylinder), and air bag expansion is to push knife lid
Far from cutter hub, air pump is inflated quantitative change hour, and air bag becomes smaller, and for then knife lid under the effect of gravity close to cutter hub, the present invention controls air pump
The variation of displacement is to adjust the thickness of stirring knife, so that material in gap improves material constantly by the extruding on vertical
Kneading effect.To sum up, the present invention can be engaged material at dead angle, and the kneading effect of material entirety can be improved.
Further, it is interference fitted bushing in the venthole, stretches out active transmission cylinder outside bushing and forms outlet nozzle, air bag
Air inlet set outlet nozzle on and use pipe clamp clamping so that from venthole export air be rapidly introduced into air bag, avoid
Overflowing for gas dissipates.
Further, the recess portion for being inserted into and being slidably connected for knife lid is provided on the cutter hub top surface, processing is simpler, can
Realize sliding connection structure,
Further, the number of teeth of the driving gear/driven gear number of teeth=1:2, so that driving gear and driven gear
Revolving speed it is different, avoid active stirring knife and driven stirring knife from rotating between the two interference, and the engagement that material can be improved is imitated
Fruit.
