Technical field
The present invention relates to a kind of reparation side of roll surface wearing amount after the roll wear of crushing roll mill in ceramic machinery
Method.
Background technology
In ceramic machinery, crushing roll mill roll wear amount be accurately controlled in actually used in be very difficult to realize
's.Because cutting agency is time under raw material to be broken to twin rollers entrance, generally arrange at thickness and roll surface axis direction
The most uneven, although roll surface hardness is higher, but often will soon go out under the conditions of the crushing operation that this blanking is uneven
The phenomenon that existing roll surface wearing amount is uneven.All of twin rollers has striker plate at the side of roller, this be prevent from treating brokenly expecting from
Side is missed and is not entered a kind of necessary component that roll surface is broken.And near the region of roller side on side block flitch, at striker plate
Effect under, material to be broken can not be adjacent to striker plate and enter and crush between two rollers.This has resulted in twin rollers two roll surface and has leaned on
Treating broken by central area, material ratio all the time treats brokenly that material is few under the region of nearly both sides striker plate, be reflected on roll surface is exactly both sides
Limit wear extent all the time can be fewer than intermediate means wear extent.Meanwhile, middle wear extent as the inequality of blanking and cause
Rough wavy roll surface, arises that between two rollers, some places gap is the biggest in the course of time.If not reconditioning
Words, the roll surface of dual-side may produce the phenomenon collided.In this case, first, twin rollers crushing effect is the most bad,
Particle size after cracking changes the most greatly, and discharging situation is highly unstable；Second, mechanicalness can be caused to damage roller during two roller EDGE CONTACT
Evil, thus have impact on the service life of whole roller.
In the prior art, the abrasion inequality of roll surface is carried out reconditioning and has following two Chinese patent technology.A kind of special
Profit: ZL 201220473343.6, on twin rollers base, arranges the longitudinal drive lead screw longitudinally driven, abrasive machine by reductor
Big palette and longitudinal drive lead screw threaded engagement, enable emery wheel mechanism to move along the axial reciprocating of longitudinal drive lead screw.Emery wheel
Mechanism is while motor drives emery wheel to rotate, and ball-screw also drives it to move left and right thus roll surface is carried out grinding, thus
Reach to repair the purpose of roll surface.
Another kind of patent: ZL 201520552922.3, setting one in twin rollers body position can move along Y direction
Have slide, and set up drive mechanism.On this slide unit, it is provided with the second Power Drive Unit the cutter that can slide along X-axis simultaneously
Frame.When roll surface wearing amount is excessive, twin rollers stops crushing operation, re-uses drive mechanism and allows the knife rest on slide unit walk X respectively
Axle and the Y direction twin rollers i.e. roll surface of roller volume are repaired.
Above-mentioned prior art achieves roller and need not remove, and directly sets up emery wheel mechanism or slide block tool block at twin rollers
Roll surface carries out the purpose of reconditioning.Relative to the way of grinding again that dismounting roller is got off, above-mentioned technology tentatively solves roller
The most quick detachable and install, mobile difficulty, the problem wasted time and energy.But above prior art is all two lateral wearings occur at roll surface
A kind of post-processing method that uneven or roll surface is carried out after there is choppiness abrasion, finds that roll surface has that wear extent is excessive can not be continued
Just stop crushing operation after production, by the first drive mechanism and the second drive mechanism, roll surface is repaired.It is also required to simultaneously
Guard shield that dismounting roll shaft is peripheral or housing, first a roller is carried out independent reconditioning good after, then another one roller is repaiied
Mill.Grinding tool itself uses more mechanism to realize own rotation and X, the movement of Y direction, thus grinds on roll surface
Cut motion.
Summary of the invention
The technical problem to be solved in the present invention changes conventional twin rollers crushing operation to be stopped and grinding-roller sub-surface exactly
Restorative procedure, need not by means of external force to drive grinding block device in broken running, be allowed to during crushing operation
Two roll surfaces are carried out grinding reparation simultaneously.
The present invention provides a kind of restorative procedure for twin rollers grinding roller, using twin rollers roll surface grinding block as grinding
Carrier tool, is first arranged on each grinding block on elastic device and adjusting means, then by all grinding blocks, elastic device and
Its adjusting means is positioned at two rollers and parallels to the axis lower zone, by elastic device, grinding block and both sides roll surface EDGE CONTACT,
Upwards being adjacent to roll surface along two roller centrages, then raw material drops down onto among two rollers from top to bottom, and twin rollers starts broken raw material operation,
Grinding block carries out grinding repair to two rollers simultaneously, and adjusts grinding block to two rollers simultaneously by adjusting means
Carry out the regional location of grinding reparation.
Described grinding block is imitative roll forming grinding block or oblique wedge grinding block.
Frosted granularity on described grinding block has carse, medium and small three kinds of different sizes, to balance grinding block stock removal and roller
Broken stock removal.
The monolateral arc length of described grinding block is less than 1/4 its corresponding roller girth.
Described adjusting means is adjustable screw mandrel or railroad.
Use roll surface grinding block can produce bigger contacting with the roll surface of circumferencial direction as grinding carrier tool, grinding block
Face, makes circumferencial direction grinding more uniform, is also beneficial to the stationarity of operating in the running.
Frosted granularity on grinding block has carse, medium and small three kinds of specifications, and produced by different frosted granularities, ground effect is not
Equally, when grinding block generation stock removal is inconsistent with crushing operation generation wear extent, come by changing varigrained grinding block
Finding equilibrium point, this is to be allowed to a kind of method that both wear extenies reach consistent.
The installation site of grinding block be positioned at two rollers parallel to the axis lower zone and with both sides roll surface EDGE CONTACT, and edge
Two roller centrages are upwards adjacent to roll surface, and at this moment broken material drops down onto in roller from top to bottom.Grinding block meet above-listed shape and
After status requirement between roller, the compensation that can the abrasion of grinding block own vol obtain is particularly important, and grinding away, protruding roll surface is same
Time grinding block self also consume quality and volume, this just require grinding block use elastic device mode to be adjacent to roll surface.
During reconditioning, part volume and quality that grinding block loses can allow the follow-up self-compensation situation of elastic pressure abrading block be allowed to
Continue to be adjacent to roll surface, so can keep initial reconditioning state.The but mill of grinding block self under gradually crushing operation
Damage can be to a situation that can not be adjacent to roll surface by elastic compensating, and this just requires in the grinding block connected mode with compensation mechanism
Employing removably connects mode, when grinding block can not then change a new grinding block used time.
Understanding from roll surface wearing analysis and test run, the roll surface wearing amount near striker plate region, both sides is minimum
, in the case of usual crushing operation grinding block be on the downside of two rollers and with EDGE CONTACT position.Adopt in the axial direction simultaneously
It can be allowed to move left and right with adjustable screw mandrel or railroad, roll surface by middle part when corrugation face occurs, can
To repair it by mobile abrading block.
Compared with prior art, the invention has the beneficial effects as follows, first, allow reconditioning quality that roll surface produces by grinding block with
The wear extent that roll surface is produced by crushing operation is consistent, so makes roll surface still have good surface linearity after constantly abrasion,
Not affecting the stability continuing to produce and can keep discharging-material size below, grinding block produces the time of ablation to roll surface simultaneously
Also being consistent with the crushing operation time, i.e. during crushing operation, roller carries out reconditioning the most simultaneously.Second, grinding block can
Uniaxially to move along roll surface, make the irregular wear surface of some waveforms of middle appearance also can be arrived by mobile grinding block
Reach this region, allow roller own rotation just can reach the purpose that finishing is protruding under grinding block contact conditions.Grinding block is along roll surface
Uniaxially move and decrease X, Y-direction twin shaft moves required extra drive mechanism, it is only necessary to handwheel drives grinding block to mesh
Behind mark region, then fix it and be allowed to axially can not move axially again at this.The condition of the inventive method is simple, and step has
Limit, cost is relatively low, and efficiency is higher.

Then can produce the component to the center of circle with roll surface when contacting, this component is that grinding block grinds away mainly rubbing of roll surface raised zones
Wiping power is originated.Under the conditions of same frosted granularity grinding block, roll surface stock removal and elastic device 4 put on grinding block and roller
The linear ratio of pressure size of 3, crushing operation wear extent should be consistent to roll surface stock removal with grinding block.The work of elastic device 4
The big of stock removal can also be adjusted by power F that regulation is applied on grinding block with not only making grinding block self-compensating wear extent
Little, just increasing elastic device 4 is in the pressure of grinding block less for actually used middle grinding block stock removal, and stock removal is excessive, reduces elasticity
Device 4 is applied to the pressure on grinding block.
Can regulate stock removal according to the varigrained grinding block of the employing that foregoing is proposed, its thickness is at roll surface
Produced stock removal is also different, and roll surface stock removal is i.e. selected relatively coarseness grinding block at least, otherwise to roll surface grinding
Amount greatly will finer grain grinding block.Elastic device 4 is shut down with grinding block mechanism at twin rollers or is remained in open state
Act on roll surface.Without often dismantling or install this mechanism, only grinding block elasticity pressure need to be regulated in conjunction with practical situation
Power or change varigrained grinding block.
