Abstract
The utility model relates to a kind of positive feed and demolding structure of twin-roll coal dust single lead screw ex truding briquetting machine.Comprise that there is the cylinder of many row's die cavitys on two surfaces, cylinder end is equipped with gear wheel, is connected with pinion, bevel gear, sprocket wheel feeding screw.Push rod, roller, axle are connected, and realize and force to follow the tracks of charging, extrusion modling stripping structure.Have rational in infrastructure, Wu Simei district, force follow the tracks of charging, forced stripper mechanism, performance safety is reliable, moulded coal pressure is large, quality is good, the advantage that intensity is high can be widely used in the industry that civilian, industrial various powders need moulding.
Description
Technical field
The utility model belongs to a kind of coal dust single lead screw ex truding briquetting machine, relates in particular to a kind of force to follow the tracks of charging, the Enforced stripping structure of extrusion modling.
Background technology
Existing coal dust extruder, to drive two cylinders in relative rotation by motor through transmission system, on cylinder surface, be covered with half mould die cavity, coal dust adds between two cylinders, after being brought into die cavity, arrive horizontal position extrusion modling, in the time that shaping mould cavity turns over centre bit, it is large that two die cavity spacing become gradually with the rotation of cylinder, makes moulding ball automatically leave die cavity and fall down.The shortcoming of this structure coal dust extruder is: 1,, because coal dust proportion is little, angle of repose is large, there is no mobility, is difficult for entering die cavity, is difficult to be formed with the coal briquette of certain pressure; 2, all in coal dust, add a certain proportion of binding agent for making coal dust can push balling-up; 3, the die cavity fineness of two cylinders not etc., the coal dust amount inequality entering, the coal briquette of extruding to the bonding force of two die cavitys not etc., there will be coal briquette to be bonded in the groove of certain cylinder, impact continues charging extruding, causes overload; 4, between the adjacent die cavity of cylinder surface, be larger area dead band, this part coal dust is compressed on cylinder surface, and more pressure is thicker, harder, causes extruding overload, damages structure.
Summary of the invention
The purpose of this utility model is the defect existing for above-mentioned existing coal dust ball press, and charging, Enforced stripping structure are followed the tracks of in a kind of pressure that there is no dead band proposing.
The purpose of this utility model is achieved in that and comprises that two bored rolls in relative rotation, cylinder surface have many row's short cylindrical shape die cavitys, and the fixing gear wheel of cylinder end is connected with pinion, and pinion is contained on little axle.Bevel gear on little axle is connected with the bevel gear on vertical shaft, and the hinge wheel on sprocket wheel and feeding screw on vertical shaft is joined by chain, follows the tracks of charging, extrusion structure thereby realize; Push rod is separately housed in die cavity, and push rod end is equipped with roller, is connected with cam fixing in axle, and axle and cylinder have eccentric e at α angle place, thereby realize Enforced stripping structure.
The utlity model has following advantage: |
1, between the column type die cavity of cylinder surface, there is no dead band, there is minimizing power consumption, the advantage that can not transship part of damage.
2, feeding screw can be synchronizeed with drum speed ceaselessly continuous feed, can realize the finished product of certain pressure intensity.
3, Enforced stripping structure, can realize pressure large, and intensity is high, not the excellent results of sticking to mould.
4, rational in infrastructure, easily manufacture safe ready, few easy workout part.
Brief description of the drawings
Fig. 1 is that charging extrusion pressing type schematic diagram is followed the tracks of in pressure of the present utility model.
Fig. 2 is forced stripper mechanism schematic diagram of the present utility model.
