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 control according to its structure and controlled with hydraulic pressure, manual control mode：Pass through
Handwheel is selected to control screw mandrel stroke, and then controls spacing between roller, due to can not accurately predict the gap separated between roller, Zhi Nengyi
Working condition is probably estimated by modes such as range estimation roll surface bed of material colors, real-time pressure between roller can not be known.For grinding to pressure
The sensitive material of power is more passive, and grinding quality substantially reduces.
Hydraulic control mode：By hydraulic jack provide roller between pressure, for grinding high-viscosity material when, can pass through
Pressure controls the thickness of the bed of material, but because Stress control is that constant pressure provides, when intermittence is fed and ground, does not have between roller
When having material, phase mutual friction between roller and roller, roll body Rapid Damage is caused, reduce roller service life, in grinding low viscosity thing
During material, material can not push roller open, will also result in situation about can not grind with roll body damage.
Chinese invention patent《Accurately control the roll squeezer of gap and pressure between roller》(publication number：CN
A kind of roll squeezer 102744118A) is disclosed, passes through the spacing between eccentric wheel adjusting roller.Although this roll squeezer can be timely
Adjusting roller spacing, but still can not know the real-time pressure between roller, pressure and clearance mode can only isolated operation, Wu Faxiang
Mutually monitoring.And once there is foreign body intrusion in operation between the roller, local pressure can be caused between roller excessive and damage roller, roller
Pressure between cylinder can not be effectively controlled.
The content of the invention
The technical problem to be solved in the present invention is：It is difficult to adjust for the roller spacing of roll squeezer in the prior art, it is difficult to
It is determined that suitable pressure, reduces grinding quality, shorten the technical problem of roller service life, between the present invention is provided between a kind of roller
The roll squeezer of gap and pressure controllable.
The technical solution adopted for the present invention to solve the technical problems is：The roll-in of gap and pressure controllable between a kind of roller
Machine, including fixing roller, movable roll and support base, fixing roller are parallel to each other with movable roll, the both ends of the fixing roller and movable roll
Both ends fixed respectively by stationary roller shaft bearing and activity roll bearing seat, the stationary roller shaft bearing be provided with bearing block on
Cover, cover on bearing block and fixed with the support base, described activity roll bearing seat one end is fixed with movable roll, activity roll bearing seat
The other end is rotatablely connected with support base, a projection is provided with the outside of one end of the activity roll bearing seat, the projection is close to described
Movable roll.
Also there is a governor motion, the governor motion includes clamping lever, and one end of the clamping lever passes through a peace
Full flexure strip interfixes with lid on the bearing block, and the other end of the clamping lever, which is provided with, is used for what is exerted a force to clamping lever
Eccentric wheel, the side of the clamping lever have the strong point of a power transmission mutual with the projection；The clamping lever turns
Dynamic plane and the rotational plane of the activity roll bearing seat are coplanar or parallel.When eccentric wheel rotates, clamping lever is to inside and outside shifting
It is dynamic, stationary roller shaft bearing is driven to inside and outside movement, so that the gap of movable roll and fixing roller changes therewith, control eccentric
The anglec of rotation, so as to reach the controllable function of adjustment clearance between roll.Wherein, safety elastic piece is to protect between roller once exist
There is foreign body intrusion in operating, when thrust is more than the intensity of safety elastic piece between roller, safety elastic piece will be stretched up to fracture,
So as to protect roller without prejudice.According to the corresponding shearing force of the different designs of material, and by adjusting on the clamping lever
Supporting point position realize, without redesign miscellaneous part.Further, since the size of bearing clearance will also result between roller
Gap it is inconsistent, it is necessary to by the clearance control of fixing roller bearing minimum lubrication gap, therefore, safety elastic piece need set
Put on bearing block on lid, wherein, power that the gap of fixing roller bearing can be fastened by bolts is adjusted.
The thickness range of the safety elastic piece is 0.2mm-3mm, width range 2mm-100mm.Pass through width and thickness
The combination of degree, so as to reach required security value (s), now, safety elastic piece can bear to push away between 500-30000N roller
Power.
Minimum outer diameter value of the eccentric wheel from center of rotation to outer surface is 0.5mm, maximum 20mm.Eccentric wheel limits
Center of rotation is determined to the external diametrical extent of outer surface, can be used for controlling the maximal clearance of roller and corresponding torque lever ratio.
The distance of the strong point to safety elastic piece is L1, the application point of eccentric wheel and clamping lever to the strong point away from
From for L2, L1：L2 is 0.5：20.
A torque sensor is provided between the clamping lever and eccentric wheel.When eccentric wheel operates, work as movable roll
Produce and contact with fixing roller, when further strengthening contact, torque sensor will sense the size of torque, so as to count
Calculate the size of stress between roller.The eccentric wheel anglec of rotation and torque sensor gathered data are gathered, with setting data shape
Into closed-loop control, so as to which the function of the pressure controllable between roller can be realized.
Contacted with each other between the torque sensor and eccentric wheel by an adjustment bolt.Regulating bolt and torque sensor
Threaded connection, the position between clamping lever and eccentric wheel can be preset by regulating bolt before start, can be with after start
Again by driving eccentric wheel to finely tune gap and applying pressure.
In order to improve the wearability at the strong point, extend the service life of clamping lever, one is provided with the strong point
Supporting pin, the supporting pin externally protrude out in the clamping lever.Supporting pin is not only wear-resisting, and replacing easy to disassemble.
The projection is alloy block.
The eccentric wheel is driven by motor.Eccentric wheel can be selected by manually either by stepper motor or servomotor
Control.
The invention has the advantages that the roll squeezer of gap and pressure controllable between the roller of the present invention, simple in construction, it is easy to
Manufacture, spacing that can easily between adjusting roller by eccentric wheel and clamping lever；Activity roll bearing seat lower end is movable roll
Pivot point, and activity roll bearing seat directly acts on clamping lever, makes to be delivered on clamping lever between roller intermolecular forces；
Once there is foreign body intrusion in operation between roller, when thrust is more than the intensity of safety elastic piece between roller, safety elastic piece will be by
Stretching, so as to protect roller without prejudice, greatly improves grinding quality until fracture, and effectively extends the use longevity of roller
Life.
