Description
Technical field
The present invention relates to a kind of biomass granule fuel former, particularly a kind of concentric eccentric shaft of biomass forming machine
Clearance adjustment mechanism.
Background technology
Ring mode granulator is by the relative rotation between ring moulds and pressure roller by the loose biomass material such as wood chip, straw powder material
It is pressed into dense granule, the gap length of die squash type biomass pellet fuel forming machine ring moulds and pressure roller is to granule-forming machine
Service behaviour have a major impact, common clearance adjustment method is that pressure roller shaft is processed into eccentric shaft, i.e. pressure roller shaft two is fixed
Certain offset be present between axis and the axis of rotation of pressure roller that support end determines, when adjusting gap, stretch out one in pressure roller shaft
Side applies torque, it is relatively fixed after pedestal rotates to an angle and is positioned between change die after minimum clearance.On the one hand, tied
Structure limits, and the bearing assembly of installation is placed in the biomass moulding intracavitary of closing in pressure roller, and material bears acutely to extrude in the intracavitary
With friction so that intracavitary dust concentration is big, sealing is poor, meanwhile, cavity temperature is higher, poor radiation, causes bearing assembly work
It is extremely severe to make environment, bearing is easily damaged, and equipment failure rate is high.Do not block when on the other hand, to make adjustment gap and the side of installation
Just, centering type pressure roller shaft both sides mounting shaft hole gap is larger, and fit precision is not high, with serious vibration and is hit often in production
Hit, influence mould and pressure roller life-span, improve production cost.
The content of the invention
The invention aims to make up prior art defect, there is provided one kind solves traditional eccentric shaft type gap adjustment
The biomass forming machine synchronization clearance adjustment mechanism of mechanism drawback, each surface of revolution is concentric type in pressure roller shaft, installed in pressure roller shaft
The bearing at both ends is isolated with discharge chambe, is easy to seal and is lubricated, and can effectively improve the working life of bearing；Pressure roller both ends branch
Hold, higher installation accuracy can be ensured；Die gap is easy to adjust, and Adjustment precision is high, and pressure roller positioning is reliable.
The technical solution adopted in the present invention is：Including the forming cavity upper cover plate with charging aperture, forming cavity lower cover, ring
Mould, press roll component, discharging opening, it is characterized in that：At least one set of diacytic type press roll component with one heart is vertically installed in forming cavity, ring moulds
Wedge-shaped constricted zone is formed between the maximum outer round surface of inner surface and each pressure roller, the two axial ends of pressure roller pass through sliding bearing respectively
Coordinate with eccentric axis seat, eccentric axis seat endoporus has eccentric distance with its external cylindrical surface, and upper and lower eccentric axis seat passes through its outside cylinder
Mounting hole corresponding with forming cavity upper cover plate, forming cavity lower cover is engaged assembling respectively in face, forms eccentric structure and forms and presses
The two-end bearing support of roller；Upper and lower eccentric axis seat is connected by synchronous adjustment connecting plate.
The positive effect of the present invention is：Pressure roller two supports, higher installation accuracy can be ensured；Concentric shafts eccentric slot
Adjust simple in construction, die gap is easy to adjust, and Adjustment precision is high, and pressure roller positioning is reliable；Simultaneously installed in the axle at pressure roller both ends
Hold and isolate with forming room, be easy to seal and lubricate, the working life of bearing can be effectively improved, improve the service life of equipment,
Reduce production cost.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is that ring moulds are held to be assembled on the upper and lower cover plate of forming cavity by the spring bearing of upper end and the shaft with gear of lower end and shown
It is intended to.Sequence number in figure：Forming cavity lower cover 2, forming cavity upper cover plate 3, ring moulds component 4, shaft with gear hold 4-1, spring bearing 4-3,
Press roll component 6, spout 7.
Fig. 2 is ring moulds component axonometric drawing.Sequence number in figure：Shaft with gear holds 4-1, ring moulds 4-2, spring bearing 4-3.
Fig. 3 is press roll component axonometric drawing.Sequence number in figure：Pressure roller 6-1, eccentric axis seat 6-2, closure 6-3, sliding bearing 6-
4, synchronous adjustment connecting plate 6-5.
Fig. 4 is press roll component top view.
Fig. 5 is the axonometric drawing of connecting plate.
Embodiment
See Fig. 1-3, four groups as shown in Figure 3 concentric diacytic type press roll component 6 be vertically arranged to the ring moulds component 4 shown in Fig. 1
It is interior, inner chamber and forming cavity upper cover plate 3 and the component material forming cavity of forming cavity lower cover 2 supported by frame 1 of ring moulds component 4；
Equally distributed multiple spouts 7, material are inserted by multiple spouts 7 on forming cavity upper cover plate 3；Between each two spout
Equipped with a set of press roll component 6, wedge-shaped constricted zone is formed between ring moulds 4-2 inner surfaces and each pressure roller 6-1 maximum outer round surface,
The biomass material of feeding is compressed into compact formed concretion state by loose condition (of surface), and is squeezed from the nib on ring moulds 4-2
Press out to form shaped granule.
See Fig. 3-5, every group of press roll component is provided with pressure roller 6-1, sliding bearing 6-4 of the pressure roller 6-1 two axial ends equipped with cooperation,
It is eccentric axis seat 6-2 outside sliding bearing 6-4, closure 6-3 is set in sliding bearing 6-4 outer end；In pressure roller 6-1 two axles
Connection boss is equipped with the upper and lower eccentric axis seat 6-2 at end, synchronous adjustment plate 6-5 upper and lower side is connected by screw upper and lower
On eccentric axis seat 6-2 connection boss（See Fig. 4 hole A）, upper and lower eccentric axis seat 6-2 is linked together, ensures adjustment gap
When up and down eccentric axis seat motion it is consistent, the angle for rotating it is identical, and so as to realize ring moulds, gap length is equal vertically with pressure roller
It is even consistent.
Upper and lower eccentric axis seat 6-2 is matched with upper cover plate 3 and 2 corresponding mounting hole of lower cover respectively by its external cylindrical surface
Charge-coupled dress.See Fig. 4, due to endoporus and the external cylindrical surface axis decentraction of eccentric axis seat, certain eccentric amount e value be present, thus it is eccentric
The shaft base structure plane of symmetry with respect to ring moulds setting angle difference when, can cause whole press roll component become with ring moulds radial position
Change, that is, when changing pressure roller with ring moulds radial clearance, eccentric axis seat 6-2 can be made on the outside of the upper and lower cover plate of material forming chamber around it
Mounting hole rotates to an angle, and the radial position of ring moulds relative with the pressure roller that eccentric axis seat coordinates changes, so as to realize two
The adjustment of person's gap length.When adjusting die gap length, the eccentric axis seat 6-2 that upper cover plate is arranged on shown in Fig. 3 is rotated, then
Because synchronous adjustment connecting plate 6-5 couples upper and lower eccentric axis seat, the eccentric axis seat of lower cover also synchronous axial system, adjust to default
Gap.
