Description
Technical field
The utility model relates to a kind of dry granulating machine, is specifically related to a kind of dry granulating machine pinch roller adjusting device.
Background technology
Dry granulating machine is applied to the production of grain products, its objective is the qualified finished granule that the powder pressing of various different mobility is become to have prescribed level.Dry granulating machine mainly comprises feed mechanism, feeding mechanism, tablet press mechanism, particle mechanism, granulating mechanism and sub-sieve mechanism; wherein the effect of tablet press mechanism is that the granular material that feeding mechanism is sent carries out compressing tablet, and tablet press mechanism comprises counter-rotational upper lower pressure wheel.The in the situation that of prior art, the position of lower pressure wheel is fixed, radial clearance when upper pressure wheel keeps compressing tablet work by two of front and back Hydraulic Cylinder between upper lower pressure wheel, shortcoming be before and after the thrust of hydraulic cylinder can complete equipilibrium, cause the parts of wheel pressing shaft front and back end can produce wearing and tearing in various degree, hydraulic oil in hydraulic cylinder, in compressed and dispose procedure, can be separated out some oil gas unavoidably simultaneously, thereby pollutes the required high quality environment of granulation; In addition, because the axial location of upper lower pressure wheel is fixing nonadjustable, so the outer face of upper lower pressure wheel always has certain height error, in the time that error exceedes 0.05mm, the outer face of upper lower pressure wheel and being installed on just there will be the powder phenomenon that leaks outside between the cover plate of pinch roller outer face.
Summary of the invention
In view of the deficiencies in the prior art, the technical problems to be solved in the utility model is to be to provide a kind of dry granulating machine pinch roller adjusting device that on tablet press mechanism, between lower pressure wheel, radial clearance regulates and axial location regulates that realizes.
For solving the problems of the technologies described above, the utility model takes following technical scheme to complete:
Dry granulating machine pinch roller adjusting device; comprise upper pressure wheel and wheel pressing shaft; upper pressure wheel is fixed on the front end spindle nose of wheel pressing shaft; it is characterized in that: wheel pressing shaft passes through bearing pivoting support in eccentric bushing; eccentric bushing rotates setting in support trepanning; eccentric bushing is connected with long handle portion, and the pommel of long handle portion is connected with cylinder.
Adopt after technique scheme, in the time that cylinder moves, will drive eccentric bushing to rotate, the rotation of eccentric bushing can change the radial position of wheel pressing shaft and upper pressure wheel, thereby the adjusting of radial clearance between lower pressure wheel in realization, and guarantee that the promotion of cylinder makes upper pressure wheel can reach enough compressing tablet dynamics, simultaneously, in said structure, can not produce oil vapour pollution.
As preferably, before and after support trepanning, arrange, the rear and front end of eccentric bushing is supported respectively by the front and back trepanning of support, eccentric bushing is axially movable setting in support trepanning, eccentric bushing cylindrical before and after support between trepanning is provided with fixed disk, worm gear, back plane bearing, axle rank, frontal plane bearing and Compress Spring in the axial direction successively, fixed disk is fixedly installed, worm gear is actively installed on eccentric bushing cylindrical, the rotation of worm gear is by worm drive, the end face that worm gear is relative with fixed disk is provided with edge cam curve, and axle rank are fixedly connected with eccentric bushing.
Adopt after technique scheme, work as rotary worm, will drive worm gear to rotate, because the worm gear end face relative with fixed disk is provided with edge cam curve, so in the time that worm gear rotates, worm gear can produce a certain amount of axial displacement, and then by back plane bearing impeller-hub rank, eccentric bushing with together with the wheel pressing shaft of installing in eccentric bushing, move axially, thereby the axial location of realizing upper pressure wheel regulates, be equivalent to realize the adjusting of axial location between upper lower pressure wheel, the outer face of guaranteeing upper lower pressure wheel remains in certain error range, avoid occurring the powder phenomenon that leaks outside.
As preferably, the connecting hole of upper pressure wheel and wheel pressing shaft front end spindle nose is bellmouth.Above-mentioned design can reduce the machining accuracy of part under the prerequisite that guarantees installation accuracy.
As preferably, the front end of wheel pressing shaft is connected with gland, and the rear end of wheel pressing shaft is connected with into water ring, the built-in cooling duct of wheel pressing shaft, and the rear end of cooling duct communicates with the water inlet of water inlet ring, and the front end of cooling duct communicates by the built-in Cooling Holes of gland and upper pressure wheel.Above-mentioned design can obtain effective cooling while making pinch roller work, and the powdery row material characteristic while avoiding pinch roller excess Temperature to compressing tablet damages.
