The utility model is more fully illustrated below with embodiment.The utility model can be presented as it is a variety of not
Same form, is not construed as the exemplary embodiment for being confined to describe here.
For ease of explanation, space relative terms such as " on ", " under " " left side " " right sides " can be used herein, for saying
The element or feature shown in bright figure is relative to another element or the relation of feature.It should be understood that except in figure
Outside the orientation shown, spatial terminology is intended to include the different azimuth of device in use or operation.If for example, in figure
Device is squeezed, be stated as being located at other elements or feature " under " element will be located into other elements or feature " on ".Cause
This, exemplary term " under " both upper and lower orientation can be included.Device can be positioned otherwise（It is rotated by 90 ° or is located at
Other orientation）, can correspondingly be explained used herein of the relative explanation in space.
As shown in Figure 1 to Figure 3, the powder dosing system in the present embodiment, including hopper 1, cabinet 2, the first spiral
Feeder 6, the second feeding screw 8 and buffer bin 7.Hopper 1 is arranged on the top of cabinet 2, and hopper 1 is provided below master and gone out
Material mouth, is connected by main discharge nozzle 11 with the charging aperture of the first feeding screw 6；The discharging opening of first feeding screw 6 is expected with buffering
The charging aperture connection of storehouse 7；The discharging opening of buffer bin 7 and it is connected, is finally exported from batching pipe 10 with the charging aperture of the second feeding screw 8
To proportion container.Said structure passes sequentially through pipeline connection, and is fixed by the frame in cabinet 2；The bottom of cabinet 2 is provided with branch
Leg 3.The bottom of buffer bin 7 is provided with weighing sensor 12.The volume of hopper 1 is larger, can accommodate more powders.Due to gravity
With the vibration of equipment, bottom powder density irregularity can be caused, or even there is also caking phenomenon.Powder in hopper 1 is first
Stirring through augering screw in feeding screw 6, it is more consistent that powder becomes density again, falls into buffer bin 7.It is slow
Slug storage capacity is smaller, and discharging is very fast, and powder is not easy aggregation, and density is more consistent；By controlling the second feeding screw 8
Augering screw rotating speed, and can more accurately control the discharging speed of powder.For the ease of automatically controlling, equipment is also configured with electrically
Part.Electric part can just be repeated no more here using the scheme control of the prior art such as PLC, SCM system.
Hopper 1, the first feeding screw 6, the propulsion of the liner and feeding screw of the second feeding screw 8 in equipment
Screw rod outer surface is nylon material.Nylon material is corrosion-resistant, coefficient of friction is small；Above-mentioned part is contacted with powder, using nylon
Material can be with the life-span of elongate member, it is to avoid material erosion falls to pollute powder., can be from stainless steel as pushing away in order to improve intensity
Enter the skeleton of screw rod.
When being broken down in order to avoid the first feeding screw 6 or the second feeding screw 8, the powder in hopper 1 is too late
When processing cause fail and waste material, be correspondingly arranged on auxiliary feed ports above the discharging opening of the second feeding screw 8；Material
The auxiliary discharging opening and auxiliary feed ports of the bottom of bucket 1 can also be used as auxiliary by aiding in discharge nozzle 5 to connect with flexible pipe connection
Pipeline；And section door is provided with auxiliary piping（Not shown in figure）.In order to adjust the flow of powder and avoid occurring pipeline
Block, it should which vibrator 4 is set on auxiliary piping.When breaking down, section door is opened, powder is led from auxiliary discharge nozzle 5
Go out to batching pipe 10 and export.The flow of powder is adjusted by adjusting the Oscillation Amplitude of vibrator 4.
Section door can be that manually-operated gate can also be electrically-controlled valve or Pneumatic valve；From reliability and cost consideration, preferred manual
Valve.
The control accuracy requirement of first feeding screw 6 is not high, not only can conveniently realize open loop by driving stepper motor
Control, and the vibration produced during stepper motor rotation also makes powder loose, is conducive to powder density to tend to consistent；Second spiral
The control accuracy requirement of feeder 8 is high, the anglec of rotation should be fed back by rotary encoder, using frequency converter closed-loop control.
In view of the second feeding screw 8 discharging speed more preferably greater than the discharging speed of the first feeding screw 6, originally set
The power of the first feeding screw 6 alternatively should be more than the power of the second feeding screw 8；To obtain higher sexual valence
Than.It is of course also possible to first feeding screw 6 is designed as into power with the second feeding screw 8 and structure is identical, using watching
Motor driving is taken, it is convenient to exchange；Use time is longer, and the second feeding screw 8 of precise decreasing is mounted above, and is used as
One feeding screw 6 is used；Improve the service life of accessory.
In order to keep the powder consistent in density into the second feeding screw 8 as far as possible, it should by the volume of buffer bin 7
It is designed as 1/10th of the volume less than hopper 1.And the weight of buffer bin 7, regulation the are measured by weighing sensor 12
The discharging speed of one feeding screw 6, keeps the position in storehouse of powder in buffer bin 7 highly stable.
As shown in figure 4, weighing sensor mounting bracket 13 is fixed in frame, biography of weighing is connected by weighing sensor 12
The top of sensor mounting bracket 13 and buffer bin 7.Weighing sensor 12 can also be connected into weighing sensor mounting bracket 13 to ease up
The bottom in slug storehouse 7.Weighing sensor 12 is also configured as one group, gathers signal jointly using 2 or 3 sensors, enters
Row feedback, not only contributes to reduce error, improves feedback accuracy, can also make the stress balance of buffer bin 7.Buffer bin 7
And second connected with flexible pipe 9 between feeding screw 8, it can be vibrated using being flexible coupling in reduction system to weighing sensor 12
Interference.
To facilitate installation, in embodiment groove can also be opened up in the fixing side of vibrator 4 and connecting tube；The groove
External diameter of the size preferably with connecting tube match；Avoid vibrator 4 from deviateing connecting tube, influence vibrating effect.
Powder metering feeding device in embodiment be particularly suitable for use in heavy dose of dispensing when, the addition of low dose of powder.It is logical
Cross and accurate low dose of powder is persistently added in mixed heavy dose of dispensing so that blending process can continuously be run；
Compared to it is existing must into tank dispensing equipment, not only efficiency high, and the utilization rate of material and equipment greatly improves.
Above-mentioned example is only intended to illustrate the utility model, in addition, also a variety of different embodiments, and these
Embodiment be all those skilled in the art after comprehension the utility model thought it is also envisioned that therefore, no longer arrange one by one herein
