Abstract
The invention belongs to powder industry technical fields, and in particular to a kind of powder high-precision quantitative feeding method, including holder, feed bin, Weighing module, screw feeder system, control unit, it is characterised in that：Weighing module obtains the weight of screw feeder system and is transferred to control unit in real time, and control unit is using approximatioss interval, the repeatedly predetermined feeding coal of driving screw feeder system completion.After screw feeder system stops feed, its vibration is waited for stop, after the weight amount stabilization of Weighing module, control unit just carries out data analysis calculating, then sends out feeding signal next time to screw feeder system.Again and again repeat feed, weigh, analysis calculate, send out instruct this logical program, to realize high-precision quantitative be fed.
Description
Technical field
The invention belongs to powder industry technical fields, and in particular to a kind of powder high-precision quantitative feeding method.
Background technology
In laboratory, or toning occasion, very micro powder material can be usually used, such as 10mg~1g etc., such as
This micro powder is unable to reach required precision usually because the wall built-up of weighing container leads to very big error.Most have at present
The method of effect is exactly to use solvent dilution method, but many occasions do not allow to dilute, such as toning, experiment, Drug packing etc., this gives
The industrialization of scientific research, formulator or micro packaging brings prodigious technical difficulty.
Invention content
In order to solve the above technical problems, the present invention provides a kind of powder high-precision quantitative feeding method, this method can
To solve the problems, such as powder high-precision feed.The technical solution adopted by the present invention is：A kind of powder high-precision quantitative feeding method, packet
Include holder, feed bin, Weighing module, screw feeder system, control unit, it is characterised in that：Weighing module obtain in real time spiral to
The weight of material system is simultaneously transferred to control unit, and control unit is using approximatioss interval, the repeatedly completion of driving screw feeder system
Predetermined feeding coal.After screw feeder system stops feed, its vibration is waited for stop, after the weight amount stabilization of Weighing module, control
Unit processed just carries out data analysis calculating, then sends out feeding signal next time to screw feeder system.Screw feeder system
Feeding coal in 1 second is no more than the 50% of setting feeding coal.
Description of the drawings
Attached drawing 1 is the schematic diagram of the present invention, in figure：1- holders, 2- feed bins, 3- Weighing modules, 4- screw feeder systems, 5-
Control unit.
Specific implementation mode
Below in conjunction with the accompanying drawings 1, it elaborates to the present invention.As shown in Fig. 1：Powder material is contained in feed bin 2, when
When screw feeder system 4 receives the feeding signal that control unit 5 is sent out, powder material will be detached from by screw feeder system 4
Feed bin 2.Due to there is powder to leave feed hopper 2, the current weight value that control unit 5 is obtained from Weighing module 3 will change,
Control unit 5 is compared according to the situation of change of this gravimetric value with preset value, then obtains the future time of screw feeder system 4
The theoretical feeding coal of unit, and send out feeding coal signal to screw feeder system 4.After receiving feeding coal signal, in feed bin 2
Powder feed bin 2 is detached under the action of screw feeder system 4, due to having powder to leave feed hopper 2 again, control unit 5 is from title
The current weight value that molality block 3 obtains changes again, control unit 5 again according to this gravimetric value situation of change with it is default
Value compares, and then obtains the theoretical feeding coal of the future time unit of screw feeder system 4, and send out to screw feeder system 4
Go out feeding coal signal.So repeat again and again feed, weigh, analysis calculates, sends out and instructs this logical program, to real
Existing high-precision quantitative feed.
