Description
Technical field
The present invention relates to screw extruder, particularly relate to the automatic bleeder of screw extruder.
Background technology
Now, screw extruder is a lot of in plastic industry application, is all that particle raw material is put into screw rod in the middle of plastic shaping
In extruder, adding heat fusing through screw extruder, allowing various raw material is that fluidised form enters mould, die cast in a mold.Typically
The raw material put into all contains a certain amount of moisture, therefore opens several aperture below screw feed mouth, to facilitate through extruding and to add
Moisture after heat flows out.Common raw material is because of less, so water can be eaily from following outlet stream containing moisture
Go out, but our raw material is the light scraps of paper of comparison now, and bigger containing moisture, and on the other hand the scraps of paper are gently easier
Water outlet is piled up, and blocks outlet, and in raw material own, water content is big, goes out water speed rapid not, adds the scraps of paper and the most relatively hold
Easily cause blocking, the most more have a strong impact on the rate of output water.
Summary of the invention
In order to solve above-mentioned technical problem, it is an object of the invention to provide a kind of screw extruder automatic draining stirring dress
Putting, smooth and easy for the water of extruder outlet discharge can be had simple in construction, implement convenient feature by this device.
In order to realize above-mentioned purpose, present invention employs following technical scheme:
A kind of screw extruder automatic draining agitating device, this device includes motor, drive sprocket, driven sprocket, bearing
Seat, bearing, fixing seat and crank slot roller；Described fixing seat is " U " type structure, and the upper/lower terminal of fixing seat is respectively arranged with
Installing hole, is respectively arranged with linear bearing in installing hole, described crank slot roller is arranged in fixing seat, the outer ring of crank slot roller
Circumferencial direction is provided with crank slot, and the medial wall of described fixing seat is provided with the fixing axle of protrusion, and fixing the tip of the axis is contained in
In crank slot；And the upper end of crank slot roller is provided with axle head, lower end is provided with lower shaft end, and upper axle head and lower shaft end are respectively provided with
In linear bearing, the upper end of upper axle head is provided with eccentric stirring-head, and lower shaft end is provided with spline, and described driven sprocket is arranged
Spline, lower shaft end is had to be connected with each other with spline by spline with driven sprocket；Described bearing block is arranged under fixing seat
Side, the upper end of driven sprocket is arranged in bearing block by location jump ring, and bearing is arranged on upper end and the bearing block of driven sprocket
Between, chain and drive sprocket are passed through in the lower end of driven sprocket, and drive sprocket is connected with motor.
As preferably, described fixing the tip of the axis is provided with little bearing, and described little bearing is contained in crank slot.
As preferably, described bearing block is bolted and is arranged on below fixing seat, and described bearing is two,
It is provided with positioning sleeve between two bearings.
As preferably, described motor is fixedly installed on fixing seat outer right wall.
Due to the fact that and have employed above-mentioned technical scheme, the eccentric stirring-head of this device can move up and down, again because being
Eccentric, during roller rotates, this stirring-head will do a circular trace, so the track of this stirring-head is circular
Curvilinear motion, this eccentric orbit diameter is substantially the most in the same size with extruder outlet, thus can effective lighter by the inside
Raw material empty, water can be discharged smoothly.The present invention has simple in construction, implements convenient feature.
Accompanying drawing explanation
Fig. 1 is the mounting structure signal of the present invention.
Fig. 2 is the structural representation of the present invention.
Fig. 3 is the structural representation of bearing block.
Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is made a detailed explanation.
A kind of screw extruder automatic draining agitating device as shown in Figure 2, this device include motor 1, drive sprocket 2,
Driven sprocket 4, bearing block 5, bearing 13, fixing seat 6 and crank slot roller 8；Described fixing seat 6 is " U " type structure, fixing seat 6
Upper/lower terminal be respectively arranged with installing hole, be respectively arranged with linear bearing 7 in installing hole, described crank slot roller 8 is arranged on
In fixing seat 6, the outer ring circumferencial direction of crank slot roller 8 is provided with crank slot 12, and the medial wall of described fixing seat 6 is provided with protrusion
Fixing axle 11, the end of described fixing axle 11 is provided with little bearing 10, and described little bearing 10 is contained in crank slot 12.And
The upper end of crank slot roller 8 is provided with axle head, and lower end is provided with lower shaft end, and upper axle head and lower shaft end are separately positioned on linear axis
In holding 7, the upper end of upper axle head is provided with eccentric stirring-head 9, and lower shaft end is provided with spline, and described driven sprocket 4 is provided with flower
Keyway, lower shaft end is connected with each other with spline by spline with driven sprocket 4.As it is shown on figure 3, described bearing block 5 passes through spiral shell
Bolt 16 is fixedly installed on below fixing seat 6, and the upper end of driven sprocket 4 is arranged in bearing block 5 by location jump ring 15, bearing 13
Being arranged between the upper end of driven sprocket 4 and bearing block 5, described bearing 13 is two, is provided with between two bearings 13
Positioning sleeve 14.The lower end of driven sprocket 4 is by chain and drive sprocket 2, and drive sprocket 2 is connected with motor 1, described motor
1 is fixedly installed on fixing seat 6 outer right wall.
As it is shown in figure 1, the charging aperture 17 that raw material is from screw extruder 18 top puts into, screw extruder 18 bottom has one
Outlet 19, is exactly the automatic draining agitating device of our design below outlet 19.This device drive sprocket 2 is carried by motor 1
Dynamic, after driven sprocket 4 rotates, because driven sprocket 4 is decided to be at above-below direction, so can not slide up and down, only
One rotary action, such crank slot roller 8 also rotates under the effect of sprocket wheel, but because having a little bearing 10 in crank slot 12, should
Little bearing 10 is fixed, so when crank slot roller 8 rotates, under the effect of little bearing 10, also can transport up and down with fixing seat 6
Dynamic, therefore, this crank slot roller 8 axle is upper and lower rotary motion.On crank slot roller 8, axle head has an eccentric stirring-head 9, rolls at crank slot
During wheel 8 about, this bias stirring-head 9 will move up and down, again because of being off, during roller rotation,
This stirring-head will do a circular trace, so the track of eccentric stirring-head 9 is circular curve motion, and this eccentric orbit diameter
Basic the most in the same size with extruder outlet 19, thus effectively the lighter raw material of the inside can be emptied, allow the water can be suitable
Smooth discharge.
