Description
Technical field
The utility model relates to roll squeezer technical field, the controlled roller of gap and pressure between especially a kind of rollerPress.
Background technology
Original roll squeezer is divided into manual lead screw control and hydraulic pressure control according to its structure, manual control mode:Select to control screw mandrel stroke by handwheel, and then spacing between control roll, divide owing to cannot accurately predicting between rollerFrom gap, can only rely on the modes such as range estimation roll surface bed of material color probably to estimate working condition, cannot knowReal-time pressure between roller. Comparatively passive to pressure-sensitive material for grinding, Grinding Quality reduces greatly.
Hydraulic control mode: provide the pressure between roller by hydraulic jack, during for grinding high-viscosity material,Can control by pressure the thickness of the bed of material, but because pressure control is that constant pressure provides, in gapWhen property supplies abrasive lapping, while thering is no material between roller, phase mutual friction between roller and roller, causes roll body Rapid Damage,Reduce roller service life, in the time grinding low viscosity material, material cannot be pushed roller open, and also can cause cannotGrind situation about damaging with roll body.
Chinese utility model patent " can accurately control the roll squeezer in gap and pressure between roller " (publication number: CN102744118A) a kind of roll squeezer is disclosed, by the spacing between eccentric wheel adjusting roller. This roll squeezerAlthough adjusting roller spacing in time, still cannot know the real-time pressure between roller, pressure and gapPattern can only isolated operation, cannot mutually monitor. Once and on-streamly when between the roller have a foreign body intrusion,Can cause between roller local pressure excessive and damage roller, the pressure between roller cannot be effectively controlled.
Utility model content
The technical problems to be solved in the utility model is: for the roller spacing of roll squeezer in prior art is difficult toRegulate, be difficult to determine suitable pressure, reduce Grinding Quality, shorten the roller technical problem in service life,The utility model provides the controlled roll squeezer in gap and pressure between a kind of roller.
The utility model solves the technical scheme that its technical problem adopts: gap and pressure between a kind of rollerControlled roll squeezer, comprises stationary roll, movable roll and supporting seat, and stationary roll and movable roll are parallel to each other, instituteState the two ends of stationary roll and the two ends of movable roll and fix by stationary roller shaft bearing and movable roll bearing block respectively,Described stationary roller shaft bearing is provided with bearing block upper cover, and bearing block upper cover and described supporting seat are fixed, described workAction roller shaft bearing one end and movable roll are fixed, and the other end and the supporting seat of movable roll bearing block are rotationally connected, instituteThe outside, one end of stating movable roll bearing block is provided with a projection, and described projection is near described movable roll.
Also have a governor motion, described governor motion comprises clamping lever, and one end of described clamping lever is logicalCross a safety elastic sheet and described bearing block upper cover interfixes, the other end of described clamping lever be provided with forTo the eccentric wheel of the clamping lever application of force, the side of described clamping lever have one with the mutual power transmission of described projectionThe strong point; The rotational plane of the rotational plane of described clamping lever and described movable roll bearing block is coplanar or flatOK. In the time that eccentric wheel rotates, clamping lever, to inside and outside movement, drives stationary roller shaft bearing to inside and outside movement,Thereby the gap of movable roll and stationary roll is changed thereupon, the anglec of rotation of control eccentric, thus reach tuneThe function that whole clearance between roll is controlled. Wherein, once safety elastic sheet is on-streamly between roller to have in order to protectForeign body intrusion, in the time that thrust between roller is greater than the intensity of safety elastic sheet, safety elastic sheet will be stretched until disconnectedSplit, thereby protection roller is without prejudice. According to the corresponding shearing force of the different designs of material, and by adjustingSupporting point position on described clamping lever is realized, and does not need to redesign miscellaneous part. In addition, due toThe size of bearing clearance also can cause the gap between roller inconsistent, the clearance control of stationary roll bearing need to be existedMinimum lubrication gap, therefore, safety elastic sheet need to be arranged on bearing block and cover, wherein, stationary rollThe gap of bearing can regulate by the power of bolted.
The thickness range of described safety elastic sheet is 0.2mm-3mm, and width range is 2mm-100mm. By wideThe combination of degree and thickness, thus reach needed security value (s), and now, safety elastic sheet can bearThrust between the roller of 500-30000N.
The external diameter minimum of a value of described eccentric wheel from center of rotation to outer surface is 0.5mm, and maximum is 20mm.Eccentric wheel limits center of rotation to the external diameter scope of outer surface, can be used for maximal clearance and the correspondence of control rollMoment lever ratio.
The described strong point is L1 to the distance of safety elastic sheet, and the application point of eccentric wheel and clamping lever is to supportingThe distance of point is L2, and L1:L2 is 0.5:20.
Between described clamping lever and eccentric wheel, be provided with a torque sensor. In eccentric wheel running, whenMovable roll produces and contacts with stationary roll, and when further making contact strengthen, torque sensor will sense powerThe size of square, thus can calculate size stressed between roller. The eccentric wheel anglec of rotation and torque sensor are adoptedCollection data acquisition system gets up, and forms closed-loop control, thereby can realize the controlled merit of pressure between roller with setting dataEnergy.
Between described torque sensor and eccentric wheel, be in contact with one another by an adjustment bolt. Adjusting bolt and momentSensor threads connects, and can before start, preset the position between clamping lever and eccentric wheel by adjusting boltPut, can also be again by driving eccentric wheel fine setting gap and exerting pressure after start.
In order to improve the wearability at strong point place, extend the service life of clamping lever, described strong point place establishesBe equipped with a supporting pin, described supporting pin evagination is in described clamping lever. Supporting pin is not only wear-resisting, and is convenient toDismounting and change.
Described projection is alloy block.
Described eccentric wheel drives by motor. Can select eccentric wheel by manually or by stepper motor or watchTake Electric Machine Control.
The beneficial effects of the utility model are, the controlled roll squeezer of gap and pressure between roller of the present utility model,Simple in structure, be easy to manufacture, by eccentric wheel and the clamping lever spacing between adjusting roller easily; LiveThe pivot point that action roller shaft bearing lower end is movable roll, and movable roll bearing block and clamping lever direct effect,Make between active force, to be delivered on clamping lever between roller; There is a foreign body intrusion once on-stream between roller, work as rollerBetween thrust while being greater than the intensity of safety elastic sheet, safety elastic sheet will be stretched until rupture, thus protection rollerCylinder is without prejudice, and greatly improves Grinding Quality, and has effectively extended the service life of roller.
