Description
Technical field
The utility model relates to a kind of lash adjusting device, especially a kind of pressure roller and ring die clearance stepless adjustment device that is applicable to the circular mould biological substance curing formation machine.
Background technology
The biomass solid shaping machine is the equipment that is pressed into loose agricultural crop straw, crops industrial wood waste etc. bulk, bar-shaped and granular material.Especially ring mode biomass solid shaping machine has obtained using widely.The ring mode make-up machine has advantages such as productivity ratio height, forming, is to produce biomass moulding material enterprise preferred equipment.But there is critical piece pressure roller ring intermode serious wear problem in this equipment, and pressure roller wearing and tearing back makes ring mould and pressure roller (mould roller) gap increase, when mould rod gap increases, and material bed thickening, the pressure that needs during extruding increases, the also corresponding increase of energy consumption.And material bed blocked up, can cause in the crush zone material pressure is reduced, pressure roller can produce skidding on the ring mould, thereby is lowered into moulding mixture output, even can not press molding mass.The pressure roller wearing and tearing not only are lowered into the ratio of briquetting of moulding mixture to the influence in mould roller gap, increase production cost, and directly influence productivity ratio.Therefore, in equipment uses, realizing mould roller adjustable gaps scheme, is the research emphasis of present ring mode biomass solid shaping machine.
In existing ring mould and the nip adjusting device,, drive the rotation of eccentric shaft through rotating adjustable plate, thus the gap between adjustable ring mould and the pressure roller; Perhaps utilize locking nut to unclamp and locking, realize that mould roller gap adjusts thereby rotation activity card makes pressure roller and gap between ring mould inwall change.But above-mentioned two kinds mechanical oscillation occur and usually make nut loosening in practical application, and cause the increase in mould roller gap, thereby cause and can't produce; And many through adjustable plate adjusting cooperation link, the adjusting clearance gap is big, makes that the pressure roller and the gap of ring mould can not reliably be guaranteed, directly influences the quality of molding mass and stablizing of output.
Summary of the invention
The purpose of the utility model is the weak point that overcomes in the prior art, provides that a kind of simple in structure, gap adjustment is convenient, the stepless regulator of the pressure roller of dependable performance and ring die clearance.
For realizing above purpose; Pressure roller of the utility model and ring die clearance stepless regulator; Comprise that the elasticity that is fixedly connected on the main shaft clamps pivoted arm; Elasticity clamps two pressure roller assemblies that are arranged with on the pivoted arm, and the front end of two pressure roller assemblies is provided with by left-handed round nut and is fixedly coupled plate, and the middle part of connecting plate is provided with elasticity and clamps the thru-bolt that pivoted arm links to each other; It is rectangle that described elasticity clamps the pivoted arm middle part; Both sides are the reverse symmetry arc; The middle part that elasticity clamps pivoted arm has the centre bore that cooperates with main shaft key; The bilateral symmetry of centre bore has two side openings that match with two pressure roller assemblies respectively, and two side openings lean on arcuate directions one side to have the gap one, and the plane perpendicular with the gap is provided with soket head cap screw.
Described pressure roller assembly is made up of eccentric shaft and the pressure roller that is fixed on the eccentric shaft.
Beneficial effect:, when needing the adjustment roll-in, only need unclamp thru-bolt and round nut with the ring die clearance owing to adopted technique scheme; Position through adjustment pressure roller assembly; Make that the gap changes between pressure roller and the ring mould inwall, measure gap between pressure roller and the ring mould inwall, need lock soket head cap screw after the value of adjustment when the gap reaches; Stripped nut and thru-bolt are particularly useful for the biomass solid shaping machine simultaneously.Compared with present technology, it is simple in structure, can realize the stepless adjustment in gap, makes the gap adjustment between pressure roller and the ring mould convenient, practical, reliable.

The specific embodiment
An embodiment to the utility model is further described below in conjunction with accompanying drawing:
Like Fig. 1, shown in Figure 2, pressure roller of the utility model and ring die clearance stepless regulator mainly are made up of elasticity clamping pivoted arm 2, pressure roller assembly 3, connecting plate 4, round nut 5, thru-bolt 6.Elasticity clamps pivoted arm 2 and is connected on the main shaft 8 of cuber through double key system; Two pressure roller assembly 3 symmetries are located at elasticity and clamp on the pivoted arm 2; Pressure roller assembly 3 is made up of eccentric shaft 3-1 and the pressure roller 3-2 that is fixed on the eccentric shaft 3-1, and the pressure roller 3-2 of two pressure roller assemblies 3 matches with ring mould module 7 respectively.The front end of two pressure roller assemblies 3 is provided with by round nut 5 and is fixedly coupled plate 4, and the middle part of connecting plate 4 is provided with elasticity and clamps the thru-bolt 6 that pivoted arm 2 links to each other; Centrosymmetric two pressure roller assemblies 3 are fixed on elasticity through soket head cap screw 1 and clamp on the pivoted arm 2, with connecting plate 4 two pressure roller assembly 3 front ends are connected, and fix through round nut 5, and with thru-bolt 6 connection are pulled 4 and connect with main shaft.
As shown in Figure 3; Elasticity clamps pivoted arm 2 structure charts, and it is rectangle that described elasticity clamps pivoted arm 2 middle parts, and both sides are the reverse symmetry arc; The middle part that elasticity clamps pivoted arm 2 has the centre bore that cooperates with main shaft 1 key; The bilateral symmetry of centre bore has two side openings that match with two pressure roller assemblies 3 respectively, and two side openings lean on arcuate directions one side to have the gap one, are provided with soket head cap screw 1 with perpendicular plane, gap.Centre bore is connected on the cuber main shaft through two keys, and two side holes connects the pressure roller assembly.
