Description
Technical field
This utility model relates to field of plastics manufacture, is specifically related to a kind of extrusion mould-outlet self-checking device.
Background technology
At present, major part PS(polystyrene) foam sheet extruder, it is all by changing that the thickness of its extrusion sheet adjusts
Become what interior local gap between die lip 5, outer die lip 4 realized.Concrete structure is shown in Fig. 3.Uniform on the outer ring circumference of die lip 4 outside
There are 12 location hole, outside uniform 12 screws on the inner ring relevant position of die lip 4, screw built-in regulation bolt, regulate bolt
Through the screw on inner ring, and insert in hole, location.When there is the phenomenon of became uneven the sheet material local of extrusion, adjusted by rotation
Joint bolt, regulation bolt acts on the active force of the outer ring of outer die lip 4 and will change, the inner ring of outer die lip 4 can be made to produce small
Elastic deformation so that outer die lip 4 changes with the gap of interior die lip 5 corresponding position, so that the thickness of extrusion sheet obtains
To adjust.The mode major defect of this regulation thickness is: needing to make outer die lip 4 inner ring produce elastic deformation, metal produces bullet
Property deformation need bigger external force, relatively elaborate when therefore adjusting；And regulation regulates bolt repeatedly, outer die lip reaches fatigue limit
After, inner ring is easily broken off, and the service life of mouth die is the longest；The most manually regulation mouth die can not correct outer die lip and interior die lip in time
The deviation of position.
Utility model content
The purpose of this utility model is to provide a kind of extrusion mould-outlet self-checking device, to solve outside existing extruder
Die lip easily ruptures because of tired, thus the relatively low mouth die life-span, and cannot correct the inclined of outer die lip and interior die lip position in time
The problem of difference.
For reaching above-mentioned purpose, base case of the present utility model is as follows:
Extrusion mould-outlet self-checking device includes die body, core body, interior die lip and outer die lip；Also include controller and connection
Body, described connector one end is fixedly connected on die body, and the connector other end is provided with location dish；Described outer die lip center is provided with rank
Ladder hole, outer die lip one end is fixed with capping, and shoulder hole big side wall surrounds positioning chamber with capping end face；Described location dish sets
Put in positioning chamber, and in positioning chamber, be additionally provided with strainer；The circumferential side wall of described positioning chamber and location dish circumferential side wall it
Between there is gap, the circumferential side wall of described outer die lip is provided with multiple equally distributed Pneumatic top bar one, corresponding on outer die lip
Sidewall in interior die lip is provided with and Pneumatic top bar one pressure transducer one to one, and pressure transducer and Pneumatic top bar equal
It is connected with controller；Described die body, connector, outer lip mould, core rod and epipharynx die combination go out runner.
The principle of this programme extrusion mould-outlet self-checking device is:
The strainer arranged in positioning chamber, can make the end face of location dish and the end face of shoulder hole fit tightly；And position
Having gap between circumferential side wall and the location dish circumferential side wall in chamber, outer die lip can move up in the week of connector, i.e.
Moving process is only outer die lip and the axiality of connector changes.The reason of the uneven thickness of extrusion sheet is, interior
Die lip occurs in that deviation with the relative position of outer die lip, and i.e. interior gap between die lip and outer die lip is uneven.
When the uneven thickness of extrusion sheet, the pressure of the sidewall of the external die lip of melted colloid in runner also can change,
And the real-time condition of this pressure will be by pressure sensor monitoring；Pressure condition is fed back to controller, controller by pressure transducer
Pressure mean values will be obtained, and the force value that this meansigma methods and each pressure transducer feed back will be compared, when the pressure of feedback
When value is more than meansigma methods, then the pressure of a pair location dish periphery of corresponding with this pressure transducer Pneumatic top bar subtracts corresponding
Little, on the contrary increase the most accordingly；Be adjusted with the axiality of external die lip with interior die lip, when pressure transducer value of feedback with
When meansigma methods is equal, then regulation terminates, and outer die lip will be in steady statue.
This programme produces and provides the benefit that:
Owing to outer die lip is set on the dish of location, and outer die lip the most all has certain amount of movement at location dish, and leads to
Real-time pressure is sent out deaf to controller by excess pressure sensor, and controls the Pneumatic top bar pressure to location dish by controller, with
Make outer die lip produce minute movement, make outer die lip again reach poised state, change its relative position with interior die lip；Therefore with
Prior art compares outer die lip without producing bigger elastic deformation, i.e. avoids outer die lip and easily ruptures because of tired, increases
The strong life-span of mouth die；And this programme can correct the deviation of outer die lip and interior die lip position in time.
Preferred version one: as the further optimization to base case, dish one end, described location is provided with annular protrusion, described
Strainer includes the disc spring being set on annular protrusion, and disc spring two ends closely connect with location dish end face and positioning chamber end face respectively
Touch.The installing space taken due to disc spring is little so that mechanism is simple, and uses disc spring can simplify installation, and is conducive to changing；And
Set annular protrusion can prevent disc spring from coming off.
Preferred version two: as the further optimization to preferred version one, described outer die lip can be axial relative to location dish
Mobile, described annular protrusion is corresponding with shoulder hole small end, and described location dish is provided with installing hole, and described strainer also includes pressure
Force control valve and the Pneumatic top bar two being fixed in installing hole, Pneumatic top bar two top is pressed in described capping, described Stress control
Valve is connected with Pneumatic top bar two.In this preferred version, control Pneumatic top bar two by pressure-control valve and can promote outer die lip
Move axially relative to location dish, thus the gap of outer die lip and interior die lip can be changed, so that this device adapts to multiple series
Extrusion sheet, and adjust mode the most more convenient；Additionally, due to disc spring in compression process, its two ends always with location dish and
Positioning chamber end face is in close contact, and therefore butterfly valve also acts as isolation runner and the effect of positioning chamber.
Preferred version three: as the further optimization to preferred version two, also include the display screen being connected with controller, institute
Stating pressure-control valve is electromagnetic valve, and pressure-control valve is also connected with described controller.In this preferred version, on a display screen
The value in gap needed for the interior die lip of input and adventitia lip, Stress control pressure valve will be adjusted by controller, make Pneumatic top bar two right
The pressure change of outer die lip, promotes outer die lip to move axially relative to location dish.
