Abstract
The invention relates to a high-precision spiral feeding device which is used for a transporting, packaging and metering device of powder material. The device comprises a feeding cylinder with a vertical shaft and a feeding shaft which is arranged coaxially with the feeding cylinder; the outer surface of the feeding shaft is provided with a spiral feeding blade; a discharge hole is arranged at the lower end of the feeding cylinder; a radial interval through which the material can pass is arranged between the inner wall of the feeding cylinder and the brim of the spiral blade; a baffle plate is arranged at the lower end of the feeding cylinder; the discharge hole is formed within the range of the centre of the baffle plate axially opposite to the end surface of the feeding shaft; the closed part of the baffle plate around the discharge hole is axially opposite to the spiral feeding blade, and a gap through which the material moves in the radial direction is arranged between the lower end face of the feeding shaft and the baffle plate. According to the high-precision spiral feeding device, the technology prejudice that the discharge hole needs be opposite to the spiral feeding blade in the existing spiral feeding technology is overcome, and the precision of outputting the material is effectively improved.
Description
Technical field
The present invention relates to a kind of high-precision spiral feeding device, be used for conveying, packing and the metering outfit of granular material.
Background technology
In the conveying of granular material, packaging facilities and the metering outfit, often the output of granular material being carried out accurate measurement need be set, to guarantee the measuring accuracy in packing and the course of conveying.For granular material; The spiral conveyer structure is the material export structure of using always; The spiral conveyer structure of common axial discharging includes feeding tube cylindraceous and the feeding shaft that has helicallobe that is positioned at the feeding tube center; Have discharging opening in the feeding tube end, unobstructed for guaranteeing discharging, discharging opening must have axial part over against helicallobe usually.This spiral discharge device is when being rotated output function to granular material; The flow of material output is controlled by the rotating speed and the helical pitch of helicallobe fully; Because the degree of firmness of granular material zones of different are difficult to be consistent; Thereby cause the discharge uniformity of material to reduce, thereby the material output accuracy can't reach higher level, be difficult to adapt to the requirement that some are exported with high precision in a small amount.
Summary of the invention
Technical matters to be solved by this invention is, a kind of simple in structure, high-precision spiral feeding device that output accuracy is high is provided.
High-precision spiral feeding device of the present invention comprise feeding tube with vertical axle center and with the feeding shaft of the coaxial setting of feeding tube, the feeding shaft outside face is provided with defeated material helicallobe, the feeding tube lower end is provided with discharging opening; Has the spaced radial that can supply material to pass through between said feeding tube inwall and the helicallobe edge; Said feeding tube lower end is provided with baffle plate, and said discharging opening is opened at the baffle plate center shaft to the scope over against the feeding shaft end face, and the baffle plate enclosure portion around the discharging opening is axially over against defeated material helicallobe; Has the gap that can supply material to move radially between said feeding shaft lower surface and the baffle plate.
Said feeding tube is the taper of hypomere diameter less than the epimere diameter.
Said feeding shaft lower surface is provided with inner cavity, can be mobile certain spatial cache, the stability of raising material output of providing of material.
The diameter of said discharging opening is not more than the feeding shaft diameter, and is not less than 1/2nd of feeding shaft diameter.
The present invention has overcome that discharging opening must be over against the technological prejudice of defeated material helicallobe in the defeated material technology of existing spiral; With helicallobe over against end face seal; And, make material before arriving discharging opening, bear the extruding between helicallobe and the end baffle earlier with the entity part of discharging opening over against the feeding shaft center, when slowing down its flowing velocity; Make it have consistent degree of firmness; Under the squeese pressure effect between the material, move laterally to discharging opening again, reduced the material output order of magnitude that the helicallobe spinning movement produces, thereby improved the precision of material output effectively; Because material semen deposition degree is mainly adjusted through the mode of gap between adjustment feeding shaft lower surface and the baffle plate and then the suffered squeese pressure of change material; The helical pitch of basic and defeated material spiral is irrelevant, so helicallobe need not accurately to cooperate with the feeding tube inwall, has not only reduced difficulty of processing; Simultaneously can use the bigger taper feeding tube of volume; Improve the space flowing power of material,, help improving output accuracy to guarantee the homogeneity of granular material degree of firmness.
Description of drawings
Fig. 1 is the axial section structural representation of the embodiment of the invention.
The specific embodiment
As shown in the figure, this high-precision spiral feeding device comprise feeding tube 1 with vertical axle center and with the feeding shaft 2 of the coaxial setting of feeding tube, the feeding shaft outside face is provided with defeated material helicallobe 3, the feeding tube lower end is provided with discharging opening 4; Has the spaced radial 5 that can supply material to pass through between said feeding tube 1 inwall and helicallobe 3 edges; Feeding tube 1 lower end is provided with baffle plate 6, and discharging opening 4 is opened at the baffle plate center shaft to the scope over against the feeding shaft end face, and the baffle plate enclosure portion around the discharging opening 4 is axially over against defeated material helicallobe 3; Has the gap 7 that can supply material to move radially between feeding shaft 2 lower surfaces and the baffle plate 6.Feeding tube 1 is the taper of hypomere diameter less than the epimere diameter.Feeding shaft 2 lower surfaces are provided with inner cavity 8, can be mobile certain spatial cache, the output stability of raising material of providing of material.The diameter of discharging opening 4 is not more than the feeding shaft diameter, and is not less than 1/2nd of feeding shaft diameter, according to different materials, can regulate output accuracy through the size that changes discharging opening.
In the working process of the present invention; The granular material that is contained in the feeding tube moves down under the driving of defeated material helicallobe; Owing to stopping of baffle plate is squeezed granular material; And reaching certain degree of firmness, the horizontal squeese pressure effect between material is moved to the discharging opening output at center then.Through regulating the gap between output shaft lower surface and the baffle plate, can regulate the order of magnitude of discharging, the stable discharging of lesser amt can improve the discharging precision effectively.Through the practical adjustments test, traditional relatively screw conveying device, the output of its granular material is more prone to adjust the precision that reaches higher.
