Biomass block-making machine mould roller gap stepless regulator
Technical field
The utility model relates to biomass block-making machine, more specifically, is a kind of biomass block-making machine mould roller gap stepless regulator.
Background technology
Biomass block-making machine is that a kind of compression by pretreated biomass castoff makes plant equipment that is efficient, environment-friendly fuel.Ring mold type biomass briquetting machine has the advantages such as productivity ratio is high, energy consumption is lower, becomes the main flow equipment of current biomass curing molding gradually.But this equipment deposits the problem that in use critical piece pressure roller and ring mould wear and tear gradually, after wearing and tearing, ring mould and pressure roller (mould roller) gap increase, and when mould roller gap increases, the raw material pulverized cannot enter discharging channel holes, and then charging is had an impact, cause producing stopping.The ring mold type biomass briquetting machine of prior art, its pressure roller shaft is an eccentric shaft, and rotatable pressure roller shaft regulates the gap between pinch roller and module, but above-mentioned clearance adjustment method often adjusts secondary ring mould and a nip, need to adjust multiple locking nut, coordinate link many, the gap adjustment degree of accuracy is low, on the one hand consuming time, effort, on the other hand, very high requirement is proposed to the technical ability of operator, once adjust improper, the service behaviour of cuber will be had a strong impact on; And above-mentioned clearance adjustment method often occurs that mechanical oscillation make nut loosening in actual applications, and causes the increase in mould roller gap, and then impact is produced.
Summary of the invention
The utility model for the deficiency of the gap adjustment inconvenience of existing ring mold type biomass briquetting machine pressure roller and ring mould, and provide one make mould roller gap adjustment convenient, accurately, biomass block-making machine mould roller gap stepless regulator reliably.
The technical scheme in the invention for solving the technical problem is: a kind of biomass block-making machine mould roller gap stepless regulator, comprises driven wheel, eccentric bushing and retreat stop block; Described driven wheel is fixedly connected with gear shaft, be arranged on below connecting plate by gear shaft and nut, the eccentric bushing engaged with it is arranged in the pressure roller shaft of biomass block-making machine, pressure roller is arranged on eccentric bushing by bearing, retreat stop block is bolted on connecting plate side, and the teeth of retreat stop block are meshed with the teeth of eccentric bushing.
This biomass block-making machine mould roller gap provided by the utility model stepless regulator, when needing adjustment pressure roller and ring die clearance, first unclamp nut, unload retreat stop block, rotational driving gear again, regulate pressure roller and ring die clearance by the bias of eccentric bushing, stop operating after gap reaches the value needing to adjust and fix retreat stop block.Compared with prior art, its structure is simple, can realize mould roller gap step-less adjustment, and can avoid the mould roller space change because mechanical oscillation cause, meet ring mold type biomass briquetting machine manufacturing technique requirent better.
