Abstract
The present invention discloses a fly cutter apparatus of a mixer granulator. The apparatus includes a motor and a fly cutter rotating with a motor shaft; the motor is mounted on a flange; and the motor shaft passes through the center hole of the flange and is in fixed connection with a rear shaft end of the main shaft. The apparatus is characterized in that the rear segment of the main shaft has larger diameter; a spindle sleeve rotatably sleeves on the excircle of the rear segment of the main shaft; the spindle sleeve is fixedly arranged into the center hole from the inside of the flange; the front inner hole of the spindle sleeve is provided with a plurality of axial narrow grooves on the inner pore circumference; the front segment of the main shaft has smaller diameter; the fly cutters are mounted in the front segment of the main shaft; the fly cutter closest to the rear segment of the main shaft and the shaft stage of the main shaft are separated by a seal cover; the excircle of the seal cover is provided with a reverse spiral groove; and the rear segment excircle of the seal cover rotatably cooperates with the front inner hole located in the shaft sleeve. The apparatus can reversely take out the materials in the gap between the main shaft and the sleeve cover to avoid rotation freezing of the main shaft, to prevent contamination of materials caused by falling of metal scrap generated by metal friction, and to reduce processing cooperation difficulty between the main shaft and the sleeve cover.
Description
Technical field
The present invention relates to a kind of mixer-granulator, be specifically related to a kind of fly knife device of mixer-granulator.
Background technology
Mixer-granulator is by fuselage as support, and pot is container, and stirring rotation with the transmission of cutting fly cutter is power, stirs material with paddle, and tumble mixed is even at short notice to make material, then makes particle by cutting fly cutter, finally discharges from discharging opening.In prior art, the fly knife device of mixer-granulator operationally, the greatest problem existed is in material easily enters between main shaft and axle sleeve fit clearance and retains for a long time, if compact block formed by material, main axis just can be caused time serious stuck, or produce metal friction between main shaft and axle sleeve and cause metal iron filings, metal iron filings fall into contaminated material in material, this is that pharmaceutical factory is definitely unallowed, can cause inventory disposal by the gross; Further, because the fit clearance between main shaft and axle sleeve will strictly control, increase processing and coordinate difficulty.
Summary of the invention
In view of the deficiencies in the prior art; the technical problem to be solved in the present invention is that providing a kind of oppositely can take out of the material entered between main shaft and axle sleeve in fit clearance; avoid main axis stuck; prevent metal friction from causing metal iron filings and fall into contaminated material in material, reduce main shaft simultaneously and between axle sleeve, process the mixer-granulator fly knife device coordinating difficulty.
For solving the problems of the technologies described above, the present invention takes following technical scheme:
Mixer-granulator fly knife device, the fly cutter comprising motor and rotate with motor shaft, motor is arranged on flange, motor shaft is fixedly connected with the rear axle head of main shaft through flange center hole, it is characterized in that: the back segment diameter of axle of main shaft is larger, the back segment cylindrical of main shaft is slidingly connected axle sleeve, axle sleeve is fixing inside flange to be loaded in flange center hole, the front end endoporus of axle sleeve is circumferentially provided with some axial narrow tanks at endoporus, the leading portion diameter of axle of main shaft is less, fly cutter is arranged on the leading portion of main shaft, separated by spacer between fly cutter, separated by sealing shroud near between the fly cutter of main shaft back segment and main shaft axle rank, sealing shroud is fixed on main shaft, sealing shroud cylindrical offers reverse acting spiral groove, the back segment cylindrical of sealing shroud is rotatably assorted and is located at the front end endoporus of axle sleeve.
The width of axial narrow tank is not more than 2.5mm.
The length that sealing shroud back segment cylindrical is located at axle sleeve front end endoporus is not less than 8mm.
After adopting technique scheme, when fly knife device operationally, the rotation direction of sealing shroud is identical with main shaft but contrary with spiral fluted rotation direction direction (therefore claiming reverse acting spiral groove), material near axle sleeve front end can leave to the direction away from axle sleeve under the effect of reverse acting spiral groove, even if some materials enter axle sleeve front end endoporus, these materials also can not be accumulated in the fit clearance between sealing shroud and axle sleeve, but enter in axial narrow tank, and then be reversed under the effect of the reverse acting spiral groove of sealing shroud back segment cylindrical and take out of, therefore main axis can be avoided stuck, and prevent metal friction from causing metal iron filings to fall into contaminated material in material, the problem that inner hole of shaft sleeve brings is entered owing to solving material, therefore main shaft, process quality of fit between sealing shroud and axle sleeve also can reduce, reduce main shaft, between sealing shroud with axle sleeve, processing coordinates difficulty.
As preferably, rear-end of spindle cylindrical is fixed with overcoat, be provided with front and back lip packing between overcoat and flange center hole, leave space between overcoat and axle sleeve rear end, the endoporus hole wall in the flange center hole of this clearance position is provided with inflatable mouth and ambient pressure source of the gas is connected.Above-mentioned design has two objects: one is to provide and blows afloat gas, is auxiliaryly blown out outward by the material entering axle sleeve front end endoporus; Two are to provide and blow afloat gas, and the water entering inner hole of shaft sleeve after being cleaned by fly cutter blows out outward, guarantees the sealing of motor output end.
