Abstract
The utility model discloses a pair-roller type hob grinder which comprises a housing, a motor and two roller shafts, wherein the upper end of the housing is provided with a material inlet, the lower end of the housing is provided with a material outlet, two ends of each roller shaft are respectively provided with a bearing, an external bearing room is fixedly arranged on a housing body, belt pulleys or chain wheels are arranged on the shaft ends of one sides of the roller shafts and are in driving connection with the motor, rollers are arranged on the roller shafts, the rollers are provided with roller teeth and tooth grooves along the axial direction, the roller teeth and the tooth grooves are triangular, and the roller teeth and the tooth grooves of the two rollers are arranged with one another in an interlaced way. Radial grooves are formed in the conical surfaces of the roller teeth to form a knife edge. According to the pair-roller type hob grinder disclosed by the utility model, the two rollers are driven by the motor or other engines, and are oppositely rotated, and a material is put into the material inlet formed above the two rollers, and is quickly crushed under the action of the extruding and the shearing kneading between the two rollers, so that the production efficiency can be improved, the grinder is good in a material smashing effect, and the grinder is good in adaptability.
Description
Technical field
The utility model relates to a kind of pair roller type hobboing cutter pulverizer, belongs to the size reduction machinery technical field.
Background technology
At present, two roll bodies of known pair roller type pulverizer are cylinders, pull out groove on the face of cylinder, the parallel placement of two rollers, disc is circumscribed, and the defective of this kind pulverizer is pulverizer when work, and granule materials easily skids between two rollers, frictional heating increases energy consumption, and the specific yield energy consumption is high.
The utility model content
For defects, the utility model provides a kind of pair roller type hobboing cutter pulverizer, and the processing materials conformability is good, and crushing effect is desirable, and production efficiency is high.
To achieve these goals, the technical solution of the utility model is: a kind of pair roller type hobboing cutter pulverizer, comprise casing, motor, roll shaft, and the casing upper end arranges charging aperture, the lower end arranges discharging opening.Described roll shaft is two, end, roll shaft two ends arranges bearing, the outer bearing chamber that arranges is fixedly mounted on the housing, on the one side shaft end of roll shaft belt pulley or sprocket wheel are set, be connected with motor-driven, on the described roll shaft roller be set, described roller arranges roller tooth and teeth groove vertically, described roller tooth and teeth groove are triangle, and roller tooth and the teeth groove of two rollers are staggered.
Further, on the described roller tooth conical surface radial groove is set, forms blade.
As to improvement of the present utility model, described casing is divided into the capable guide rail of horizontalization, described casing is divided into left shell and right shell body, described left shell and right shell body are mobile at closed slide by mobile device, the right-hand member of right shell body arranges baffle plate, elastic device is set on the baffle plate and the right shell body wall offsets; The left end of left shell arranges the screw mandrel adjusting device, is connected with left shell.
Further, described elastic device is spring.
Further, described screw mandrel adjusting device comprises a Fixed Nut, and the screw mandrel and the left shell that pass Fixed Nut are hinged, and the rotation handwheel is set on the other end of screw mandrel.
Pair roller type hobboing cutter pulverizer of the present utility model, two rollers are driven by motor or other engine, opposite direction rotating, material drops into from the charging aperture of two rollers top, the effect that between two rollers, is squeezed, shears, rubs, material is by broken rapidly.Housing can be divided into left and right housing, the left shell left end arranges screw screw mandrel adjusting device, can regulate the gap of two rollers, thereby regulate the fineness degree of pulverizer crushing material, the right-hand member of right shell body arranges elastic retaining device, the spring of stop device is selected the larger spring of elastic force, under normal duty, right shell body is not mobile, and the gap between two rollers does not change, when being mingled with harder impurity in the material, right shell body can in time move right, harder impurity passes through between two rollers smoothly, does not damage roll surface, thereby guarantees the safe operation of pulverizer.Pulverizer production efficiency of the present utility model is high, and crushing material is effective, and conformability is good.
