Description
Technical field
The present invention relates to roll squeezer technical field, the roll squeezer of gap and pressure controllable between especially a kind of roller.
Background technology
Original roll squeezer is divided into manual lead screw to control to control with hydraulic pressure according to its structure, manual control mode: select to control screw mandrel stroke by handwheel, and then spacing between control roll, owing to cannot accurately predict the gap be separated between roller, the modes such as range estimation roll surface bed of material color can only be relied on probably to estimate working condition, real-time pressure between roller cannot be known.Comparatively passive to pressure-sensitive material for grinding, Grinding Quality reduces greatly.
Hydraulic control mode: provide the pressure between roller by hydraulic jack, for grinding high-viscosity material time, the thickness of the bed of material can be controlled by pressure, but due to Stress control be that constant pressure provides, when intermittence is for abrasive lapping, when not having material between roller, phase mutual friction between roller with roller, causes roll body Rapid Damage, reduce roller service life, when grinding low viscosity material, roller cannot be pushed open by material, also can cause the situation cannot ground and damage with roll body.
Chinese invention patent " accurately can control the roll squeezer of gap and pressure between roller " (publication number: CN102744118A) discloses a kind of roll squeezer, by the spacing between eccentric wheel adjusting roller.Although this roll squeezer can adjusting roller spacing in time, still cannot know the real-time pressure between roller, pressure and clearance mode can only isolated operations, cannot mutually monitor.And once on-streamly have foreign body intrusion when between the roller, local pressure between roller can be caused excessive and damage roller, the pressure between roller cannot be effectively controlled.
Summary of the invention
The technical problem to be solved in the present invention is: the roller spacing in order to roll squeezer in prior art is difficult to regulate, be difficult to determine suitable pressure, reduce Grinding Quality, shorten the technical problem in roller service life, the invention provides the roll squeezer of gap and pressure controllable between a kind of roller.
The technical solution adopted for the present invention to solve the technical problems is: the roll squeezer of gap and pressure controllable between a kind of roller, comprise stationary roll, movable roll and supporting seat, stationary roll and movable roll are parallel to each other, the two ends of described stationary roll and the two ends of movable roll are fixed respectively by stationary roller shaft bearing and movable roll bearing block, described stationary roller shaft bearing is provided with bearing block upper cover, bearing block upper cover and described supporting seat are fixed, described movable roll bearing block one end and movable roll are fixed, the other end and the supporting seat of movable roll bearing block are rotationally connected, a projection is provided with outside one end of described movable roll bearing block, described projection is near described movable roll.
Also there is a governor motion, described governor motion comprises clamping lever, one end of described clamping lever is interfixed by a safety elastic sheet and described bearing block upper cover, the other end of described clamping lever is provided with the eccentric wheel for exerting a force to clamping lever, and the side of described clamping lever has the strong point of one and the mutual power transmission of described projection; The rotational plane of described clamping lever is coplanar or parallel with the rotational plane of described movable roll bearing block.When eccentric wheel rotates, clamping lever, to inside and outside movement, drives stationary roller shaft bearing to inside and outside movement, thus the gap of movable roll and stationary roll is changed thereupon, the anglec of rotation of control eccentric, thus reaches the controlled function of adjustment clearance between roll.Wherein, safety elastic sheet is to protect between roller once on-streamly have foreign body intrusion, and when when between roller, thrust is greater than the intensity of safety elastic sheet, safety elastic sheet will be stretched until rupture, thus protection roller is without prejudice.According to the corresponding shearing force of the different designs of material, and realized by the supporting point position on the described clamping lever of adjustment, and do not need to redesign miscellaneous part.In addition, the size due to bearing clearance also can cause the gap between roller inconsistent, needs the clearance control of stationary roll bearing in minimum lubrication gap, therefore, safety elastic sheet needs to be arranged on bearing block and covers, and wherein, the power that the gap of stationary roll bearing can be fastened by bolts regulates.
The thickness range of described safety elastic sheet is 0.2mm-3mm, and width range is 2mm-100mm.By the combination of width and thickness, thus reach required security value (s), now, thrust between the roller that safety elastic sheet can bear 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 diametrical extent of outer surface, can be used for the maximal clearance of control roll and the moment lever ratio of correspondence.
The described strong point is L1 to the distance of safety elastic sheet, and the application point of eccentric wheel and clamping lever is L2, L1:L2 to the distance of the strong point is 0.5:20.
A torque sensor is provided with between described clamping lever and eccentric wheel.When eccentric wheel running, contact when movable roll produces with stationary roll, when making contact strengthen further, torque sensor will sense the size of moment, thus can calculate size stressed between roller.The eccentric wheel anglec of rotation and torque sensor image data are gathered, forms closed-loop control with setting data, thus the function of the pressure controllable between roller can be realized.
Adjust bolt by one between described torque sensor and eccentric wheel to contact with each other.Adjusting bolt is threaded with torque sensor, can preset the position between clamping lever and eccentric wheel by adjusting bolt before start, can also again by driving eccentric wheel fine setting gap and applying pressure after start.
In order to improve the wearability at strong point place, extend the service life of clamping lever, described strong point place is provided with a supporting pin, and described supporting pin evagination is in described clamping lever.Supporting pin is not only wear-resisting, and is convenient to dismounting and change.
Described projection is alloy block.
Described eccentric wheel is driven by motor.Eccentric wheel can be selected by manually or by stepper motor or Serve Motor Control.
The invention has the beneficial effects as follows, the roll squeezer of gap and pressure controllable between roller of the present invention, structure is simple, is easy to manufacture, can spacing easily between adjusting roller by eccentric wheel and clamping lever; Movable roll bearing block lower end is the pivot point of movable roll, and movable roll bearing block and clamping lever direct effect, make to be delivered on clamping lever between roller intermolecular forces; Once on-streamly have foreign body intrusion between roller, when when between roller, thrust is greater than the intensity of safety elastic sheet, safety elastic sheet will be stretched until rupture, thus protection roller is without prejudice, and greatly improves Grinding Quality, and effectively extends the service life of roller.
