Description
Technical field
This utility model relates to a kind of biomass granule fuel former, particularly a kind of biomass forming machine concentric shafts eccentric slot guiding mechanism.
Background technology
Ring mode granulation machine is by relatively rotating wood flour between ring mould and pressure roller, the loose biomass material such as straw powder material is pressed into dense granule, the service behaviour of granule-forming machine is had a major impact by die squash type biomass pellet fuel forming machine ring mould with the gap length of pressure roller, common clearance adjustment method is that pressure roller shaft is processed into eccentric shaft, i.e. pressure roller shaft two is fixed and be there is certain offset between the axis of rotation of axis that support end determines and pressure roller, when adjusting gap, stretch out side in pressure roller shaft and apply torque, make it be relatively fixed after pedestal rotates to an angle to position after minimum clearance between change die.On the one hand, architectural limitation, the bearing assembly installed in pressure roller is placed in the biomass moulding intracavity of closing, and material bears acutely extruding and friction at this intracavity so that intracavity dust concentration is big, sealing is poor, simultaneously, cavity temperature is higher, poor radiation, causes bearing assembly working environment the most severe, bearing is the most damaged, and equipment failure rate is high.On the other hand, not blocking with easy for installation during for making adjustment gap, centering type pressure roller shaft both sides install that axis hole gap is relatively big, and quality of fit is the highest, is producing often with serious vibration and shock, is affecting mould and pressure roller life-span, improve production cost.
Utility model content
The purpose of this utility model is to make up prior art defect, provide a kind of biomass forming machine solving tradition eccentric shaft type clearance adjustment mechanism drawback and synchronize clearance adjustment mechanism, in pressure roller shaft, each surface of revolution is concentric type, the bearing being arranged on pressure roller shaft two ends is isolated with discharge chambe, it is easy to seal and lubrication, it is possible to be effectively improved the working life of bearing；Pressure roller two supports, it is possible to ensure higher installation accuracy；Die gap is easy to adjust, and Adjustment precision is high, and pressure roller location is reliable.
This utility model be the technical scheme is that the forming cavity upper cover plate including band charging aperture, forming cavity lower cover, ring mould, press roll component, discharging opening, it is characterized in that: least one set concentric diacytic type press roll component is vertically installed in forming cavity, wedge shape constricted zone is formed between the maximum outer round surface of ring mould inner surface and each pressure roller, the two axial ends of pressure roller is coordinated with eccentric axis seat by sliding bearing respectively, there is eccentric distance in eccentric axis seat endoporus and its external cylindrical surface, on, lower eccentric axis seat by its external cylindrical surface respectively with forming cavity upper cover plate, the installing hole that forming cavity lower cover is corresponding matches assembling, constitute eccentric structure and constitute the two-end bearing support of pressure roller；Upper and lower eccentric axis seat is connected by synchronization control connecting plate.
Good effect of the present utility model is: pressure roller two supports, it is possible to ensure higher installation accuracy；Concentric shafts eccentric slot adjusts simple in construction, and die gap is easy to adjust, and Adjustment precision is high, and pressure roller location is reliable；The bearing being simultaneously attached to pressure roller two ends is isolated with forming room, it is simple to seals and lubricates, it is possible to be effectively improved the working life of bearing, improves the service life of equipment, reduces production cost.

Detailed description of the invention
See Fig. 1-3, four groups as shown in Figure 4 with one heart diacytic type press roll component 6 be vertically arranged in the ring membrane module 4 shown in Fig. 1, the inner chamber of ring membrane module 4 and forming cavity upper cover plate 3 and the forming cavity lower cover 2 component material forming cavity supported by frame 1；Equally distributed multiple spouts 7 on forming cavity upper cover plate 3, material is inserted by multiple spouts 7；Equipped with a set of press roll component 6 between each two spout, wedge shape constricted zone is formed between the maximum outer round surface of ring mould 4-2 inner surface and each pressure roller 6-1, the biomass material of feeding is compressed into compact formed concretion state by loose condition (of surface), and the nib from ring mould 4-2 is extruded out and forms shaped granule.
Seeing Fig. 3-5, often group press roll component is provided with pressure roller 6-1, and the two axial ends of pressure roller 6-1 is outside equipped with the sliding bearing 6-4, sliding bearing 6-4 coordinated is eccentric axis seat 6-2, arranges sealing lid 6-3 in the outer end of sliding bearing 6-4；The upper and lower eccentric axis seat 6-2 of the two axial ends of pressure roller 6-1 is equipped with connection boss, the upper and lower side of synchronization control plate 6-5 is connected by screw on the connection boss of upper and lower eccentric axis seat 6-2 (see the hole A of Fig. 4), upper and lower eccentric axis seat 6-2 is linked together, when ensureing to adjust gap, the motion of upper and lower eccentric axis seat is consistent, make its angle rotated identical, thus realize ring mould and pressure roller gap length uniformity vertically.
Upper and lower eccentric axis seat 6-2 is matched assembling by the installing hole that its external cylindrical surface is corresponding with upper cover plate 3 and lower cover 2 respectively.See Fig. 4, owing to the endoporus of eccentric axis seat is the most concentric with external cylindrical surface axis, there is certain eccentric amount e value, therefore eccentric axis seat symmetrical configuration face relative to the setting angle difference of ring mould time, whole press roll component can be made to change with ring mould radial position, when i.e. changing pressure roller with ring mould radial clearance, eccentric axis seat 6-2 can be made to rotate to an angle around its installing hole in the outside of the upper and lower cover plate in material forming chamber, the pressure roller coordinated with eccentric axis seat changes relative to the radial position of ring mould, thus realizes the adjustment of both gap lengths.When adjusting die gap length, rotate the eccentric axis seat 6-2 being arranged on upper cover plate shown in Fig. 3, then due to synchronization control connecting plate 6-5, upper and lower eccentric axis seat is coupled, the eccentric axis seat of lower cover also synchronous axial system, adjust to prepsetting gap.
