Abstract
The present invention discloses a scraper fixing structure for a granulator. The scraper fixing structure comprises scraper vertical positioning shafts, a vertical orientation bearing is arranged on each scraper vertical positioning shaft, a scraper radial positioning gear is arranged between a retaining ring and a ring die, the scraper radial positioning gear and a scraper motor driving gear are engaged directly and are located on the same horizontal line, the scraper motor driving gear is connected with a motor shaft, the scraper radial positioning gear drives a scraper transition plate to move so as to drive the scraper to rotate around a ring die axis of the granulator, and a radical positioning shaft and a radical positioning bearing are arranged above the scraper radial positioning gear, so that a scraper fixing structure with good sealing performance and convenient transmission is designed, and the radical and axial directions of a scraper are firmly fixed.
Description
Technical field
The present invention relates to a kind of granulation field of mechanical technique, particularly relate to a kind of granulator scraper fixed structure.
Background technology
The granulation mode of current granulator has screw extrusion, piston punching press, the extruding of ring mould and roll extrusion several.Typical equipment is the granulator adopting ring mould extruding granulation mode; the structure of this granulator is; two pressure rollers are set in ring mould; during work; wedge shaped squeeze room (portion) is formed at ring mould and pressure roller; by relatively rotating of ring mould and pressure roller, the material of wedge shaped squeeze indoor is extruded inner ring mould by powerful active force, completes granulation.
In addition, in the prior art, the scraper of some granulators is arranged on roller seat cover plate, see utility model (CN201445943U), scraper is the charge bar relying on the power cut provided of mair motor to extrude from granulation hole, and in such situation, granulator operating efficiency is not high; Some granulators connect the direct frame of travelling gear of scraper above ring mould, thus affect sealing; In the middle of the travelling gear clamping gear ring of some granulator scrapers, thus cause gear ring thicker; Fixing firm not in radial and axial both direction of the scraper of some granulators, see patent of invention (CN104474974A); In order to solve the problem, the present invention devises that a kind of good seal performance, transmission are convenient, firm scraper fixed structure is all fixed in the radial and axial direction of scraper.
Summary of the invention
The object of the invention is to overcome prior art deficiency, the present invention devises that a kind of good seal performance, transmission are convenient, firm scraper fixed structure is all fixed in the radial and axial direction of scraper.
In order to achieve the above object, technical scheme of the present invention is such: a kind of scraper fixed structure for granulator, is characterized in that: the lower end peripheral of granulator feeding bucket 6 has the shrouding 7 extending to back-up ring 12, and scraper drive motors is fixed on shrouding 7, multiple scraper perpendicular positioning axle 10 is fixed with in back-up ring 12 inner circumferential, each scraper perpendicular positioning axle 10 arranges perpendicular positioning bearing 14, perpendicular positioning bearing 14 is fixed on back-up ring shell, scraper radial location gear 9 is provided with between back-up ring 12 and ring mould, scraper radial location gear 9 directly engages with scraper motor driven wheel 8 and in the same horizontal line, scraper motor driven wheel 8 is connected with motor shaft, scraper radial location gear 9 drives scraper rebound 11 transmission, thus drive scraper to rotate around granulator ring mold shaft line, radial location axle 13 and radial location bearing 15 is provided with above scraper radial location gear 9.
Gear of the present invention and gear ring adopt laser cutting, and blade thickness controls in 1.5mm, and the path of contact upper blade plane that the edge of a knife is positioned at pressure roller and ring mould upwarps 3 ~ 15 degree of angles in pressure roller ring mould field of conjugate action tangent line.
Preferably; granulator according to a first aspect of the invention comprises multiple cutter; usually 4-6 is arranged; according to actual needs also more stage property can be set; multiple cutter is located relative to the outer surface of ring mould, cuts off particle, be arranged on the outer surface of the multiple scrapers in mold cavity close to ring mould for the outer surface from ring mould; to cut off particle from the outer surface of ring mould, discharge mold cavity to allow particle through particle outlet.
Accompanying drawing explanation
