The section spiral shell depth 5mm of the 21, second homogenizing zone 23, first exhaust section 20, the second exhaust section 22 spiral shells depth 7.5mm of the screw rod 12.
As shown in figure 3, the anti-overflow exhaust apparatus 26 also includes exhaust connector 31, blast pipe 32 and deposits glue case 33,
Shaftless screw device 29 passes sequentially through bearing 30, pad and is connected with exhaust connector 31 from inside to outside, exhaust connector 31,
Blast pipe 32 is integral type communicating structure with glue case 33 is deposited, and the free end of shaftless screw device 29 passes through shaft coupling 28 and motor
III27 is connected, and blast pipe 32 is located at the free end lower section of shaftless screw device 29, is communicated with the spiral section of shaftless screw device 29.
Described to dehydrate anti-overflow equipment for extruder, extruder selects second order steam vent.
As shown in Fig. 2 the vacuum extractor 1 and vacuum extractor 2 13 also include the vavuum pump 43 with motor,
The vavuum pump 43 is connected by pump-line with the glue case 33 of depositing in anti-overflow exhaust apparatus 26.
The side of direction of rotation of the anti-overflow exhaust apparatus 26 in the screw rod 12.
The utility model provides a kind of synthetic rubber dehydrating drying device, as shown in Fig. 2 the right-hand member installation axle of screw rod 12
Hold and be connected with the gear in reduction box II17 by spline tooth wheel case, drawing-in device side pressure roller forms 30 DEG C of folders with screw rod 12
Pyramid is arranged, and machine barrel uses segmentation structure, adopted between three sections of machine barrels and be bolted connection, used between machine barrel and head
Connector 5 is connected, and is fastened using bolt using threaded connection between machine barrel and connector 5, between connector and head and connected
Connect.As shown in figure 1, synthetic rubber is added via charge door, the enhancing of material feeding ability, supplies under the auxiliary of 16 side pressure roller of drawing-in device 34
Material stabilization；Under shearing, stretching action, temperature and pressure is gradually risen sizing material, and in screw compression section region, sizing material is persistently pressed
Contracting, its interior moisture is constantly extruded, and is discharged by the small osculum of extruder barrel bottom, in compression section region, inside sizing material
Most moisture is discharged by compression；Then, sizing material is successively twice by screw rod exhaust section, now, screw-rod structure screw channel depth,
Pitch is big, the increase of screw channel cavity volume, pressure reduction, while under the effect such as vacuum extractor vavuum pump, areal pressure enters one
Step is reduced, and forms sizing material negative pressuren zone, hydrone, air and low molecular weight volatile the thing effusion in glue, is arranged via vacuum extractor
Go out machine barrel, in outside condensation process, sizing material reclaimed water lease making by mechanical presses and twice overflow by negative pressure, completes dried process；Complete
The sizing material of dried process is extruded by spreader 3 by machine barrel mouth mold 1, obtains meeting the rubber product of performance requirement.
The drawing-in device 16 of this extruder mainly uses spiral drawing-in device, as shown in figure 1, feeding in drawing-in device 16
Expect that the axis of roller is in approximately the same plane and angled with the axis of driving screw, preferably 30 °；Fig. 3 is this practicality
Other press-roller device disclosed in new embodiment, because the rotation of the direction of rotation and the screw thread of driving screw 12 of the charging screw thread of propellers 34
It is on the contrary, so in the course of the work, the direction of motion of the direction of motion of driving screw 12 and feed-screw 34 is relative to turn direction
, and screw rod is synchronously incorgruous can greatly reinforce sizing material feeding ability, and such sizing material can be pushed away in the spiral of feed roller 34
Travelled forward automatically under power effect, feed roller 34 is driven alone using single motor I41, and feeding is together completed with driving screw 12,
And slowed down using reduction box I40；The feeding device 16 of this board mainly utilizes a worm reduction box I40, model
It is CW types, this TV station reduction box floor space is small, and cost is relatively low, is suitable for feeding device, due to the stress of feed roller 34 less, institute
With motor power selection without too big, 3kw power models are preferably chosen, due to axis and the main spiral shell of feeding roller 34
The axis of bar 12 is 30 °, can provide enough installing spaces for worm reduction box I40, and feed roller 34 is can guarantee that again
Spiral thrust is as big as possible in the component of the axis direction of driving screw 12, substantially increases the feeding ability of extruder, improves machine
The board ability of platform, so as to be favorably improved the quality of extruded product, improve production efficiency, improves enterprise in the market
Competitiveness.
To solve the problems, such as the overflow of extruder vent, the problem to being probably exhaust ports design presence, to exhaust outlet
Structure is improved, and the size of designed exhaust outlet should be more wider than the width of stream, thereby may be ensured that extruder
The melt sizing material that exhaust outlet is not flowed is blocked, and simultaneously, the width of extruder steam vent also should not be too big, it is therefore an objective to
In order to shorten the possibility of sizing material residence time and sizing material expansion；When sizing material flows through the exhaust section of extruder, due to exhaust segment body
Product increases suddenly, pressure reduction, causes the air molecule in flowing sizing material, hydrone and lower-molecular substance to escape, from exhaust
Taken away by vavuum pump in hole；As shown in figure 3, vacuum extractor includes anti-overflow exhaust apparatus 26, in order to prevent sizing material from exhaust
Hole is emerged, and partly added with a shaftless screw device 29 on steam vent, the drive device of this exhaust apparatus can be used directly
One small torque motor III27, is not used in configuring reduction box, and exhaust apparatus 26 is in the side of the direction of rotation of the screw rod,
So that sizing material dumping is easy；The free end of shaftless screw device 29 is connected by shaft coupling 28 with motor III27, with motor
Vavuum pump 43 is connected by pump-line with the glue case 33 of depositing in anti-overflow exhaust apparatus 26, and during operation, motor III27 drives nothing
Axle screw 29, shaftless screw device 29 rotates formed spiral thrust and prevents sizing material melt overflow, because shaftless screw
Device 29 is smaller with sizing material contact area, it is possible to larger resistance is formed to lower section sizing material, even if there is sizing material to emerge, it is also possible to
The sizing material emerged is taken out in material storing box 33 from the side；Meanwhile, vavuum pump 43 runs, and gas is from the middle of shaftless screw device 29
Hollow section is vented by blast pipe 32, and vacuum extractor realizes the exhaust of sizing material and anti-overflow function simultaneously；It should be noted that
Glue case 33 is deposited in Fig. 3 should be using drawer-type structure in the prior art, in time to remove the sizing material emerged.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or new using this practicality
Type.Various modifications to these embodiments will be apparent for those skilled in the art, determine herein
The General Principle of justice can in other embodiments be realized in the case where spirit or scope of the present utility model are not departed from.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
