Abstract
The utility model relates to a screw feed mechanism, in particular to a screw conveying mechanism of a screw feed weigher, which comprises a screw tube body with a feed hole and a discharge hole; a screw shaft driven by a motor is arranged in the screw tube body; and screw blades are arranged on the screw shaft. The screw conveying mechanism is characterized in that the horizontal screw shaft at the discharge hole is a plain shaft. The utility model mainly solves the technical problem of easy material accumulation and blocking at the discharge hole of the existing structure during the material sticking and discharge and has the characteristics of stable conveying flow rate particularly for the screw electronic weigher for continuous accumulative weighing.
Description
Technical field
The utility model relates to screw feed mechanism, particularly a kind of spiral conveying mechanism of screw feeder scale.
Background technology
Screw feeder scale (also claiming spiral electronic scales, spiral burden balance, reamer scale) is by helical blade push feed continuously in helical tube body of rotation, belongs to a kind of of continuous integration Automatic balance.It is applicable to that mainly fed distance is shorter, and operational throughput is not that the continuous integration of very big powder or granule thing is weighed.Convey materials is based on powdery, and it is big not to be suitable for viscosity, moisture height, and chiseling property of mill is big, and is hard but be afraid of the material that breaks up, and fed distance generally should not surpass 3m.The temperature of convey materials generally is no more than 200 ℃.The screw feeder biggest advantage is that cell body is airtight, and is simple in structure, compact, and the convey materials loss is little, but and the higher thermal material of delivery temperature.This equipment is widely used in industries such as building materials, chemical industry, metallurgy.
The helix transporting device structure of existing convey materials is such: it comprises the helical tube body with charging aperture and discharging opening, this helical tube body is equipped with by motor-driven screw axis, on this screw axis basically constant pitch distributing and have the helical blade of identical sense of rotation.During use, by the rotation of motor-driven screw axis, the material of charging aperture input advances by helical blade and is transported to discharging opening.But the spiral conveying mechanism of above-mentioned existing screw feeder scale in use has following shortcoming:
1. it is big not to be suitable for viscosity, and chiseling property of mill is big, hard but be afraid of the material that breaks up;
2. pile up putty easily by discharging opening during the discharging of adhesion material;
3. feed flow is stable inadequately;
4. very sensitive to the material overload.
The utility model content
The purpose of this utility model is to provide a kind of spiral conveying mechanism of screw feeder scale, it mainly solves existing structure is piled up putty easily by discharging opening when the discharging of adhesion material technical matters, especially, have the stable characteristics of feed flow for the weigh spiral electronic scales of usefulness of continuous integration.
The technical solution of the utility model is as follows:
A kind of spiral conveying mechanism of screw feeder scale, it comprises the helical tube body with charging aperture and discharging opening, is equipped with in this helical tube body by motor-driven screw axis, installs on this screw axis by helical blade; It is characterized in that: the structure of described flat spin axle at the discharging opening place is optical axis.
The spiral conveying mechanism of described screw feeder scale is characterized in that: described screw axis top discharge mouth is opposite to the sense of rotation of the helical blade between the screw axis far-end bearing with discharging opening to the helical blade at near-end bearing place.
The spiral conveying mechanism of described screw feeder scale is characterized in that: the pitch B of described helical blade by the charging aperture end is less than the pitch A of front end helical blade.
Compare with existing structure, the advantage that the utility model had is:
1. because the structure of screw axis at the discharging opening place is optical axis, on-bladed, be convenient to the discharging of adhesion material, do not stop up, make the convey materials constant flow;
2. because the helical blade spiral of screw axis at the end bearing place at discharging opening place is reverse acting spiral, can protect end bearing;
3. because screw axis at the reverse acting spiral of discharging opening place end convolution blade, can not cause extruding and putty by the opposite end cover, keep material unimpeded;
4. because the pitch of leaning on the charging aperture end less than front end conveyor screw blade pitch, is unlikely to make material too much to be deposited in charging aperture, can not cause extruding and putty by the opposite end cover.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure:
The 1-helical tube body;
The 11-charging aperture;
The 12-discharging opening;
The 2-screw axis;
31,32-helical blade.
Embodiment
See also Fig. 1, the utility model discloses a kind of spiral conveying mechanism of screw feeder scale.As shown in the figure: it comprises the helical tube body 1 with charging aperture 11 and discharging opening 12, is equipped with in this helical tube body 1 by motor-driven screw axis 2, installs on this screw axis 2 by helical blade; It is characterized in that: described flat spin axle 2 is optical axises in the structure at discharging opening 12 places.
Described screw axis 2 top discharge mouths 12 are opposite to the sense of rotation of the helical blade 32 between the screw axis far-end bearing with discharging opening 12 to the helical blade 31 at near-end bearing place.
The pitch B of described helical blade 32 by charging aperture 11 ends is less than the pitch A of front end helical blade 32.
In the utility model device uses, be transferred material from charging aperture 11 chargings, rotation by screw axis 2, helical blade 32 by dextrorotation drives material toward discharging opening 12 propellings, the pitch B of charging aperture 11 place's helical blades is less than the pitch A of front end conveyor screw blade, be unlikely to make material too much to be deposited in charging aperture 11, can not cause extruding and putty by the opposite end cover; Screw axis 2 is optical axis, on-bladed in the structure at discharging opening 12 places, is convenient to the discharging of adhesion material, does not stop up, and makes the convey materials constant flow; Helical blade 32 between charging aperture and discharging opening is dextrorotation blades; be convenient to the propelling of material in the material chamber; and the helical blade 31 of material discharging opening 12 near-end bearing portions is left-handed blades; material can be realized reverse propulsion at this place; so that protection end bearing; can not cause extruding and putty by the opposite end cover, keep material unimpeded.
Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
