Detailed description of the invention
A kind of sintering machine automatization trailing type head-tail sealing device as shown in Figure 1, its structure is: seals and is fixed with in the middle of roller 1
Rolling bearing, rolling rod is coated with 40～60mm thick high temperature resistant elastomeric materials, and elastomeric material contacts with band 2 with outside,
And rotate under it drives.Tranverse connecting rod 5 one end is welded on bearing, and the other end is hinged with heel post 8, and middle part connects
Having hydraulic cylinder 3, tranverse connecting rod 5 can move up and down around heel post 8 under the effect of hydraulic cylinder 3 together with sealing roller 1.Hydraulic pressure
Cylinder 3 other end is hinged with the pallet 13 being welded on heel post 8.Heel post 8 is fixed on bottom support frame 12, bottom
Bracing frame 12 bears all installation weights, and is fixed in slideway supporting side walls.Cylinder 4 is driven to be separately mounted to expanding pulley 6
The both sides of bottom support frame 12, wherein expanding pulley 6 is fixed near bellows 9 side, drives cylinder 4 rack-mounted away from bellows 9
Side and be connected with servomotor.Support rollers 7 is welded on heel post 8, maintains a certain distance with pallet bottom, its
Maximum height moves down residing lowest point less than sealing roller 1.Slewing rollers 10,11 are arranged in slideway supporting side walls, wherein
Guide rolls 10 is in improved bellows 9 inside grooves, and guide rolls 11 is at recess edge, guide rolls 11 and wind
Install graphite bar between case 9 additional and be in close contact with the two.Device is overall by the outer sealing band that material is high temperature resistant PSA fiber fabric
2 parcels, width is equal with chassis chute width.
The specifically used process of the present invention is introduced below in conjunction with accompanying drawing:
(1) as it is shown in figure 1, drive the external servomotor of cylinder 4 and ensure that gear ratio is 1: 1, motor accesses Central Control Room, meter
Calculate and set its rotating speed, it is ensured that Roller conveyor speed is consistent with the chassis speed of service.So outer sealing band 2 just can be at drum having
Under Dong, operate with the state static relative to pallet bottom；
(2) as it is shown in figure 1, tranverse connecting rod 5 is connected with hydraulic cylinder 3, hydraulic stem end is fixed with pressure transducer so that it is with horizontal stroke
Connecting rod 5 is in close contact.The pressure setting about 50N passes through as sensor initial pressure, the change of the pressure in plant running afterwards
Sensor signal conversion is delivered to middle control computer, controls the analysis of computer, feedback signal is applied to hydraulic cylinder 3 in passing through, and controls
It moves up and down, to ensure that pressure sensor reading maintains setting value all the time；
(3), after chassis slowly runs sealing device, by bottom girder 14 to band 2 and the extruding of sealing roller 1, change
Become the stress size of tranverse connecting rod 4, and by it, change of power is conducted to pressure transducer.When chassis runs to bottom girder 14 with close
During envelope roller 1 malleation contact position, hydraulic cylinder 3 is in minimum telescopic location.Now cover high temperature resistant seal on roller 1
Elastomer under external force, does the deformation adapting to chassis bottom girder shape, reaches the purpose of roller and the close contact of bottom girder；
(4) as in figure 2 it is shown, when chassis bottom girder 14 is slowly away from sealing roller 1, it is to roller and the extruding of band 2
Power tapers into, and hydraulic stem is persistently released, till sealing roller 1 company horizontal with bottom girder muscle 15 contact, and keep certain just
Pressure, now hydraulic cylinder 3 is in maximal dilation position, and chassis bottom girder 14 contacts with band, and band 2 is little by pallet bottom
Scope is wrapped up, and forms tight labyrinth sealing.
(5) expanding pulley 6 thrust is much smaller than pressure transducer pre set force, and sensitive to the reacting condition of power.Seal on roller 1
During shifting, bottom girder 14 crush seal band 2 all the time so that it is gradually tighten.The band 2 tightened extrudes expanding pulley 6, makes dress
Put whole perimeter to diminish, provide enough deformation length to band 2.
(6) said process repeats, and has blocked air and has entered the path of bellows from pallet bottom.On the other hand, bellows 9 warp
Cross between improved groove, guide rolls 10/11 and band 2 formation labyrinth sealing, prevent the sealed device of air with
Space between bellows wall enters bellows 9, makes device entirety reach good sealing effectiveness.
