Abstract
The utility model discloses a vertical spiral feeding device provided with an arc-shaped material-saving gate belonging to the package weighing field. The feeding device comprises a spiral housing body, in which is disposed a spiral rotating shaft. A material inlet port is disposed in an upper surface of the spiral housing body, and a material outlet port is disposed in a lower end. An arc-shaped gate is disposed on the material outlet port of the spiral housing body. By disposing the arc-shaped gate on the material outlet port, the arc-shaped gate can serve as a plugging mechanism of the spiral outlet, and the cylinder can serve as the driving mechanism of the arc-shaped gate. The feeding device provided in the utility model can solve the material leakage problem by using the angle of repose characteristic possessed by the powder particle materials effectively, and has advantages of simple structure and fast reaction speed.
Description
Technical field
The utility model belongs to packing weighing field, is specifically related to a kind of vertical spin drawing-in device.
Background technology
The vertical spin feeding is a kind of feeding form that is usually used in the general powder of flowing power, granule materials metering, and the vertical spin drawing-in device can keep materials flow even, flow speed stability, and can be through control screw shaft rotative speed, control flow velocity.
Tiny powder material finishes at feeding, after screw shaft stops operating, also has a small amount of material and flows out through gap between helicallobe and the spiral tube.For addressing this problem, several kinds of plugging mechanisms below general at present the employing 1. are designed to hollow with screw shaft, the middle pull bar of installing, and the awl cap is installed in the pull bar below, and when feeding finished, pull bar promoted, and the awl cap is sealed spiral outlet.Its plugging effect still can, but mechanism is complicated, requirement on machining accuracy is high; 2. in spiral outlet plate-turning door is set, when closing, turns on the door-plate and block spiral outlet, reach and cut the material purpose,, be prone to material folding when closing, be not closed completely because the plate-turning door closing direction is to meet to the materials flow direction; 3. horizontally rotate cover plate in the spiral outlet setting, cover plate is positioned at S. A. outlet next door, is parallel to screw shaft; Cover plate horizontally rotates, and the folding of control spiral outlet is because cover plate is dull and stereotyped; There is the gap in the middle of cover plate and the spiral outlet,, exists and leak the material phenomenon so shutoff is not tight.
Summary of the invention
The purpose of the utility model be to provide a kind of simple in structure, speed of response is fast, shutoff is tight, and can efficiently solve the Lou vertical spin drawing-in device that has the arcuate section bin gate of material problem.
The technical scheme of the utility model is following:
A kind of vertical spin drawing-in device that has the arcuate section bin gate, it comprises shaped spiral housing, is provided with screw shaft in the shaped spiral housing, and the upper surface of described shaped spiral housing is provided with inlet point, and the lower end is provided with discharging opening, and the discharging opening place of described shaped spiral housing is provided with arc-shaped door.
In the above-mentioned vertical spin drawing-in device that has an arcuate section bin gate: described arc-shaped door through the arc-shaped door axle mounting at the discharging opening place.
In the above-mentioned vertical spin drawing-in device that has an arcuate section bin gate: a side of described shaped spiral housing is fixed with cylinder block, is installed with cylinder through cylinder block, and the pull bar on the said cylinder and the edge of arc-shaped door are hinged through bearing pin.
The beneficial effect of the utility model is: through at the inlet point place arc-shaped door being set, as the spiral outlet plugging mechanism, utilize the driver train of cylinder as arc-shaped door again.The slope angle of repose characteristic that it is simple in structure, speed of response is fast and utilize powder body material self to be had efficiently solves Lou material problem.
Description of drawings
The vertical spin drawing-in device structural representation that has the arcuate section bin gate that Fig. 1 provides for the utility model;
Fig. 2 is the lateral plan of Fig. 1;
Among the figure: 1. arc-shaped door; 2. arc door-hinge; 3. cylinder; 4. cylinder block; 5. shaped spiral housing; 6. vertical spin axle; 7. discharging opening; 8. bearing pin; 9. inlet point.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further explain.
As shown in Figure 1, shaped spiral housing 5 is vertically placed, and its upper end is conical, is processed with inlet point 9 at shaped spiral housing 5 upper surfaces, and shaped spiral housing 5 lower ends are processed with discharging opening 7.Vertical spin axle 6 is installed in the shaped spiral housing 5, is installed with the screw-shaped blade on the vertical spin axle 6, it can be rotated whole vertical spin axle 6 by the driven by motor that is installed in the top.
Side at shaped spiral housing 5 is installed with cylinder block 4, through these cylinder block 4 fixed installation cylinders 3.Simultaneously arc-shaped door 1 is installed at discharging opening 7 places of shaped spiral housing 5 lower ends; As depicted in figs. 1 and 2; The circle centre position of this arc-shaped door 1 is installed on the shaped spiral housing 5 through arc door-hinge 2; Make arc-shaped door 1 can swing around arc door-hinge 2, hinge-point of the circular edges of arc-shaped door 1 design simultaneously, arc-shaped door 1 is hinged through bearing pin 8 with the pull bar on the cylinder 3 at that point.Flexible drive arc-shaped door 1 swing through cylinder 3 top rods makes discharging opening 7 open or closure.
Arc-shaped door 1 is hinged through bearing pin 8 with the pull bar on the cylinder 3 at that point, and the straight-line motion of cylinder 3 is converted into the circular movement of arc-shaped door 3, i.e. swing.
This installs mode of operation:
Initial position: cylinder 3 stretches out, arc-shaped door 1 is closed, and seals discharging opening 7, and vertical spin axle 6 is static.
When feeding begins, cylinder 3 withdrawals, driving arc-shaped door 1 is upwards swing of axle center with arc door-hinge 2, and arc-shaped door 1 is opened, and gets out of the way discharging opening 7, and after arc-shaped door 1 was opened fully, vertical spin axle 6 started, rotation, and material is carried to discharging opening from inlet point; When feeding finishes, 6 stalls of vertical spin axle, cylinder 3 stretches out simultaneously, drives arc-shaped door 1 and puts back initial position, and arc-shaped door 1 is closed, and seals discharging opening 7, stops material.Get back to initial condition, the process of finishing the work.
