Abstract
A double-group shaft coupling rolling device provided by the invention comprises two half-couplings; two bottom surfaces opposite to the two half-couplings are respectively provided with a slotted groove and a slotted boss, which is nested in the groove; two output shafts drive the two fixed half-couplings to rotate reversely with a same velocity; and when the slotted groove of one half-coupling is parallel to a line, which centers of two rollers are on, the slotted groove of the other half-coupling is perpendicular to the line, which centers of two rollers are on. According to the couplings provided by the invention, as no floating block is arranged, a wear problem on a joint of the half-couplings and the slide blocks caused by large centrifugal force due to offset caused by slide blocks can be avoided. Compared with the existing technology of one group provided with a rigid coupling device and a group provided with a floating coupling device, the invention effectively reduces jump amplitude of the floating coupling, so as to ensure the stable operation of the roller.
Description
Technical field
The invention belongs to powder former field, be specifically related to a kind of double group type shaft coupling rolling device for dry granulating machine.
Background technology
Dry granulation is directly material powder to be carried out compression forming by mechanical presses, carries out a kind of granulating process of fragmentation, granulation again, compares with wet granulation, and dry granulation technique has been omitted humidification and drying process, has saved a large amount of electric energy.Dry granulating machine is the industrial departments such as pharmacy, powder metallurgy, the former powder pressing of various low bulk densities is become the basic equipment of high bulk density particle.
Dry granulation is the compression forming that realizes raw material by rolling device, rolling device comprises actuating unit and the two rolls and the output shaft that be arranged in parallel, wherein roll is connected with actuating unit by output shaft, thereby the moment of torsion of actuating unit is sent to the rolling of roll realization roll by output shaft, and pushes sending into two raw materials between the roll.Because in the running of granulator; send into two material quantities between the roll and usually be difficult to keep from start to finish constant; when sending into the amount sudden fast rush of raw material sometime; if roll is to be connected with actuating unit by the rigidity output shaft; then can be excessive because of the extruding force that the material quantity that enters too much causes roll to be subject in operation process; cause roll to be stuck, can't run well.
Therefore, for the phenomenon that prevents that above-mentioned roll is stuck, rolling device of the prior art all is provided with shaft coupling usually, two sections rolling surface roll squeezers of a kind of pair of main shaft drives are disclosed such as Chinese patent literature CN201095194Y, this roll squeezer is provided with gear-box, gear-box has the output shaft of an input and two constant speed reverse rotations, one end key of output shaft of gear-box and syllogic cross fine setting shaft coupling connects together, the other end of syllogic cross fine setting shaft coupling and motionless pressure roller shaft are built key and are connected together, and the stage casing of this shaft coupling is mould nest centering micromatic setting; One end binding of another output shaft of gear-box and syllogic cross end-float coupling together, the other end of syllogic cross end-float coupling and unsteady roll mandrel binding are together, be equipped with at the two ends of unsteady roll mandrel can be along the bearing block of track slip, the thrust hydraulic cylinder is housed between this bearing block and the frame, and feeding device is equipped with in the top of motionless roll and unsteady roll.The syllogic cross fine setting shaft coupling that arranges on one of them output of this shaft coupling is positive coupling, when connected roll and output shaft generation off-centre, can proofread and correct by fine setting; The roll that is connected with its key is motionless roll, another roll that is connected with syllogic cross end-float coupling is the roll that floats, because the pressure of described thrust hydraulic cylinder is constant substantially, when running into putty or larger hard material, the pressure of motionless roll and unsteady roll shop building is greater than the thrust of hydraulic cylinder, force the roll that floats to be opened outward, after feeding recovered normally, unsteady roll resetted under the effect of hydraulic cylinder again.
Above-mentioned rolling device is by arranging described syllogic cross end-float coupling, can compensate certain radially, angle and axial displacement.But, the problem that above-mentioned rolling device still exists is, the intermediate slider of above-mentioned syllogic cross end-float coupling is to be in unsteady state, easily be offset, and thereby the skew of intermediate slider can make it produce larger centrifugal force so that dynamic loading increases, after long-term the use, easily wear and tear in the junction of two half a couplers and slide block, and then cause the galloping of roll, especially in above-mentioned prior art, because one of them roll is to be connected with output by positive coupling, do not possess compensating action, so operating floating compensation just all need to rely on described syllogic cross end-float coupling to carry out, thereby causes the amplitude that jumps of intermediate slider very large, and then more so that the galloping of roll, finally affect the uniformity of product particle density.
Summary of the invention
The technical problem that the present invention solves is that the intermediate slider of the syllogic cross end-float coupling of rolling device employing of the prior art is to be in unsteady state; jumping of certain amplitude easily occurs in the intermediate slider that floats in the running; thereby and intermediate slider can produce larger centrifugal force its dynamic loading is increased in the running; after long-term the use; easily wear and tear in the junction of two half a couplers and slide block; thereby the galloping that causes driven axle; affect the inhomogeneity problem of product particle bulk density, and then a kind of stable double group type hitch bar that is used for dry granulating machine is provided.
