Description
Technical field
The utility model relates to a kind of ring die pelleter, belongs to the technical field of grain forming process equipment.
Background technology
In the market the operation principle of most ring die pelleter be through the materials such as feeder wood chip after treatment, stalk byMaterial guide mechanism is sent in granulating chamber mechanism and is encircled the workspace between mould and pressure roller, and ring mould turns clockwise with certain rotating speed, pressure rollerStart to turn clockwise by the frictional force of encircling in workspace between mould, pressure roller, material, material is extruded, compresses, and at mouldAfter hole pressurize a period of time, extrude from nib, cut off through cutting knife, form required particle.
As Chinese patent CN200945426 has announced a kind of wood processing machinery. This machinery comprises along transmission shafts to symmetry extremelyFew two rotatable milling rollers, the periphery of milling roller motion circle upwards has a ring mould, and one end of ring mould is fixed in frame, ringLarge outer little bellmouth in mould footpath is upwards distributing, the periphery of ring mould has the grain-cutter of circumferential rotation, and the periphery of grain-cutter has ring mouldCover, the top of ring mould cover is connected to charging aperture, is connected to discharging opening below. The footpath of this processing equipment ring mould upwards arranges interior large outer littleBellmouth, although this structure bellmouth can make discharging density increase, easily increases the radial pressure of ring mould, thereby causesMechanical wear distortion.
Chinese patent CN102784590 ring die pelleter, particularly a kind of ring die pelletizing that is mainly used in biomass granulatingMachine. The utility model include granulator main frame (1), ring mould (4), drive (6), main shaft (8), the empty axle of main frame (9),Pressure roller assembly (10), main shaft pressing plate (13), cutting knife (28), door closure (16), tooth axle (26), Compulsory feeder used (17), enterMaterial mouthful (21) and discharging opening (22), also include demarcation strip (14) and door closure pressing plate (15), and demarcation strip (14) is connected to masterThe main shaft pressing plate (13) of axle (8) one end is upper, and door closure pressing plate (15) is arranged on door closure (16) inner side, door closure pressing plate (15)Be movably connected with demarcation strip (14). The utility model is not recorded concrete structure and the relational structure of ring mould and pressure roller.
Chinese patent CN102248696 discloses a kind of biomass grain forming module, comprises ring mould and pressure roller, wherein: described inRing mould is provided with grain forming hole; The stitching surface of described ring mould is provided with ring mould engaging tooth, the stitching surface of described pressure roller be provided withThe intermeshing pressure roller engaging tooth of described ring mould engaging tooth, described grain forming hole be positioned at two adjacent described ring mould engaging tooths itBetween.
