Description
Technical field
The utility model belongs to powder former field, is specifically related to a kind of double group type shaft coupling rolling device that is used for the dry granulation 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 technology has been omitted humidification and drying process, has saved a large amount of electric energy.The dry granulation machine is industrial departments such as pharmacy, powder metallurgy, the former powder of various low bulk densities is pressed into 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, by output shaft thereby the moment of torsion of actuating unit is sent to the rolling that roll is realized roll, 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 be difficult to keep from start to finish constant usually; when the amount of sending into raw material sometime increases suddenly; 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 subjected 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 roll-in face roll squeezers of a kind of pair of main shaft drives are disclosed 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 and the motionless pressure roller axle key of syllogic cross fine setting shaft coupling connect together, and the stage casing of this shaft coupling is a 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 is provided with on one of them output of this shaft coupling is a 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 bigger 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.
