Abstract
A full-bearing-transmission dual-roller gear granulator belongs to the field of extrusion granulation equipment. The full-bearing-transmission dual-roller gear granulator comprises a machine frame, a motor, a speed reducer and two hollow granulation gears, wherein granulating through holes are arranged in the gear root portions of the granulating gears, and the motor can driven the two granulating gears to be in mesh transmission through the speed reducer. The full-bearing-transmission dual-roller gear granulator is characterized in that the two granulating gears are arranged on the machine frame through the two granulating gears. The full-bearing-transmission dual-roller gear granulator further comprises two inner discharge barrels which are fixed on the machine frame and extend into the hollow granulating gears. Material cutting openings are arranged in the inner discharge barrels, cutters are fixed at the material cutting openings of the inner discharge barrels, and cutting blades of the cutters are in tangency with the inner peripheral walls of the granulating gears. Due to the fact that the bearing transmission is rolling frication, poor lubrication and even the clamping phenomenon caused by increasing extrusion force are avoided in processing hard or dry materials. Thus, the service life of the granulator is effectively prolonged.
Description
Technical field
The utility model belongs to extruding granulation equipment field, be specifically related to a kind of full bearing-transmission to roller gear comminutor.
Background technology
As shown in Figure 1,2,3, 4; as follows to roller gear engagement comminutor principle: the root at two hollow granulation gears 2 bores granulation through hole 9; when 2 engagements of granulation gear are rotated; material freely falls in gear grooved from two granulation gear 2 tops; utilize the engaging pressure between gear; force material to enter in the granulation through hole 9 of gear root, be compressed into column type strip-shaped materials, and stretch into the hollow part of granulation gear 2.Fixed cutting tool 8 in frame 7, cutting knife 8 stretches into the hollow part of granulation gear 2, and tangent with the internal perisporium of gear.Along with the rotation of gear, utilize cutting knife 8 that cylinder material is cut off, hollow granulation gear 2 rotates the centrifugal thrust forming, and material is released from the front of machine, completes granulation process.
But granulation gear 2 wall thickness are frivolous, be about about 10mm, the width of granulation gear 2 determined to offer granulation through hole 9 quantity number, and the quantity of granulation through hole 9 determines output size, the effective width of granulation gear 2 is generally in 100mm left and right.As shown in Figure 4; the hollow granulation gear 2 of former comminutor is arranged in frame 7 by watt axle 3; in granulation process; because granulation gear 2 wall thickness are very thin; load is born at two ends can not be excessive; and due to insufficient lubrication between granulation gear 2 and bearing shell 3, frictional force great Yi causes bearing shell 3 to heat up, and comminutor cannot long time running.At present old-fashioned all adopts abrasion-proof bearing bush transmission to tooth comminutor; thereby former meshing gear comminutor adaptation material is limited in scope; can only be suitable for some humidity large, have softer material after certain viscosity, granulating, exist rotating speed slowly, easily heat up, yield poorly, the drawback such as power consumption is large.
If simple replaces with bearing-transmission by bearing shell transmission; discharging bore will be less than the hollow diameter of bore of granulation gear 2; form stairstepping storing dead angle; material cannot be sent smoothly; therefore the application to roll shape gear comminutor and granulation object are very restricted, and are difficult to popularize.
Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of full bearing-transmission to roller gear comminutor, be convenient to carry out granulation operation for various materials energy-efficiently.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of full bearing-transmission to roller gear comminutor, comprise frame, motor, reductor and two hollow granulation gears, tooth root portion at granulation gear offers granulation through hole, motor via reducer drives two granulation gear engagements to rotate, and it is characterized in that two granulation gears are arranged in frame by bearing; Also comprise two discharging inner cores, discharging inner core is fixed in frame and stretches in granulation gear hollow, offers blank opening on discharging inner core, and at the blank opening part fixed cutting tool of discharging inner core, the internal perisporium of the blade of cutting knife and granulation gear is tangent.
Full bearing-transmission described in the utility model to roller gear comminutor, characterized by further comprising discharging screw auger, discharging screw auger is arranged on the inside of discharging inner core, with the coaxial installation of granulation gear and rotate with granulation gear synchronous.
Discharging inner core is cylindrical, coaxially installs with granulation gear.
Above two granulation gears, charging aperture is set, below two granulation gears, discharging opening is set.
The beneficial effects of the utility model are:
1, two granulation gears of the present utility model are arranged in frame by bearing, and granulation gear, in the time of engagement rolling, reduces with frame frictional force, and caloric value is few, and energy long working and power consumption are extremely low.Because bearing-transmission is rolling friction, even if processing quality harder or dry material, can because extruding force increases even there is not getting stuck phenomenon in insufficient lubrication yet, effectively extend the service life of comminutor.
2, discharging inner core is fixed in frame and stretches in granulation gear hollow, and the setting of discharging inner core has made up due to bearing being installed, and the discharging bore causing diminishes, and the internal perisporium of discharging bore place and granulation gear exists the defect of drop.On discharging inner core, offer blank opening, at the blank opening part fixed cutting tool of discharging inner core, the internal perisporium of the blade of cutting knife and granulation gear is tangent.When granulation gear rotates in engagement, cutting knife is fixed as one with discharging inner core and frame, transfixion, and the internal perisporium of the granulation gear of fitting blocks cylindrical material, and drops in discharging inner core, can not exist buildup to be detained dead angle.
3, in the inside of discharging inner core, discharging screw auger is set, discharging screw auger is with the coaxial installation of granulation gear and rotate with granulation gear synchronous.Discharging screw auger can, along with granulation process, synchronously transfer out shaping material the hollow part of granulation gear, avoids accumulating being adhered phenomenon, makes granulation discharging more efficient.
4, the utility model is simple in structure, is suitable for practicality, and production cost is lower, suitablely in the industry cycle popularizes.
