Abstract
The utility model discloses the screw extruder of a kind of axially-displaceable, the screw rod that including machine barrel, is positioned at machine barrel and being positioned on machine barrel and the discharging opening corresponding to screw feeding end, by the bearing block support being positioned on machine barrel, it rotates described screw rod, on described machine barrel, respective shaft bearing position is provided with slide rail axially along a screw, and described bearing block is driven by reciprocating device.The screw extruder of axially-displaceable of the present utility model, screw rod can move along its axial reciprocating such that it is able to increase screw rod to the extruding of material, shear action, increase boring plasticizing rate.
Description
Technical field
This utility model is a kind of screw extruder.
Background technology
Screw extruder is used for extruded rubber semi-products and goods.Screw extruder mainly by screw rod, machine barrel,
Head, feeding mechanism, actuating device and temperature control system etc. form, by screw extruding, shearing and
The effects such as stirring, make sizing material be heated private plasticizing, and are extruded continuously by the shape of the mouth as one speaks.Existing screw extruder is at spiral shell
In the case of bar rotating speed is constant, screw rod is constant to extruding, the shear action of material, the most just cannot change
Become the speed to material plasticizing.
Utility model content
The deficiency existed for prior art, the technical problems to be solved in the utility model is to provide a kind of axle
The screw extruder of Xiang Keyi, can change screw rod in the case of screw speed is constant and squeeze material
Pressure, shear action time, material plasticizing speed is made to accelerate.
To achieve these goals, this utility model is to realize by the following technical solutions: a kind of axle
The screw extruder of Xiang Keyi, the screw rod including machine barrel, being positioned at machine barrel and being positioned on machine barrel send with screw rod
Material discharging opening corresponding to end, by the bearing block support being positioned on machine barrel, it rotates described screw rod, described
On machine barrel, respective shaft bearing position is provided with slide rail axially along a screw, and described bearing block is by moving back and forth machine
Structure drives.
Further, described reciprocating device includes free bearing, connecting rod, bent axle and reducing motor, described
Free bearing is arranged on bearing block, and the two ends of described connecting rod are hinged with one end of free bearing and bent axle respectively, described
The other end of bent axle is driven by reducing motor and rotates.
The beneficial effects of the utility model:
1, the screw extruder of axially-displaceable of the present utility model, screw rod can move along its axial reciprocating
Such that it is able to increase screw rod to the extruding of material, shear action, increase boring plasticizing rate；
2, the screw extruder of axially-displaceable of the present utility model, drives the reciprocating device knot of screw rod
Structure is simple, and swing is converted into moving back and forth of bearing block and screw rod, and mechanism wear is little.
Accompanying drawing explanation
Fig. 1 is the structural representation of the screw extruder of a kind of axially-displaceable of this utility model；
In figure: 1-machine barrel, 2-screw rod, 3-bearing block, 4-chute, 5-reciprocating device, 501-
Free bearing, 502-connecting rod, 503-bent axle, 504-reducing motor, 6-motor, 7-frame, 8-discharging opening,
9-charging aperture.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be readily apparent from effect
Understand, below in conjunction with detailed description of the invention, this utility model is expanded on further.
Referring to figure, this utility model provides a kind of technical scheme: the screw extruder of a kind of axially-displaceable,
The screw rod 2 that including machine barrel 1, is positioned at machine barrel 1 and be positioned on machine barrel 1 right with screw rod 2 feeding end institute
The discharging opening 8 answered, on machine barrel 1 installation frame 7, machine barrel is provided with charging aperture 9, and screw rod 2 is by being positioned at
Bearing block 3 on machine barrel 1 supports it and rotates, and the motor 6 driving screw rod 2 to rotate is also mounted at bearing block
On 3, material enters in machine barrel 1 from charging aperture 9, and screw rod 2 rotates and by material transmission in machine barrel 1
To discharging opening 8, material is extruded while transmitting material, shears by screw rod 2.On machine barrel 1 right
Answering bearing block 3 position to be axially arranged with slide rail 4 along screw rod 2, bearing block 3 is by reciprocating device 5
Drive, while reciprocal transverse-moving mechanism 5 drive shaft bearing 3 moves back and forth, bearing block 3 spiral shell supported
Bar 2 and the motor driving screw rod 2 to rotate move back and forth also with bearing block 3, say, that screw rod
2 move along its axial reciprocating while rotating, and can squeeze material back and forth when screw rod moves back and forth
Pressure, shear, therefore can increase screw rod to material extruding, shear effect, accelerate material fusion time,
And the uniformity coefficient of plasticizing.
Reciprocating device 5 can be hydraulic cylinder, electric power push rod isoline output mechanism, straight line output machine
Structure frequently commutates and screw rod 2 just can be made to move back and forth, but the frequently commutation of straight line output mechanism needs its frequency
Numerous start and stop, cause its abrasion bigger.Reciprocating device 5 of the present utility model includes free bearing 501, connects
Bar 502, bent axle 503 and reducing motor 504, free bearing 501 is arranged on bearing block 3, connecting rod 502
Two ends hinged with one end of free bearing 501 and bent axle 503 respectively, the other end of bent axle 503 is by the electricity that slows down
Machine 504 drives and rotates, on reducing motor 504 installation frame 7.Bent axle 503 rotate through connecting rod
Moving back and forth of 502 transaxle bearings 3, reducing motor is without frequent start-stop, and equipment attrition is less.
Of the present utility model ultimate principle and principal character and of the present utility model have more than been shown and described
Advantage, it is obvious to a person skilled in the art that this utility model is not limited to above-mentioned one exemplary embodiment
Details, and in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to other
Concrete form realize this utility model.Which point therefore, no matter from the point of view of, embodiment all should be regarded as
