Description
Technical field
The invention belongs to powder industry technical fields, and in particular to a kind of continuous, uniform, the accurate charging gear of powder.
Background technique
Continuous-feeding, essence with the continuous development of the industries such as fine chemistry industry, pharmacy, food, daily use chemicals, coal, to powder
True measuring requirement is higher and higher.It is suitble to the common charging gear of powder to have screw feeder and vibrating feed in modern industrial production
Device is most widely used especially with screw feeder.The basic principle is that the rotation of the helical axis using installation helical blade, makes object
Material generates the relative motion along helicoid, and material is acted on by the frictional force of hopper and dosing tube wall to be revolved together with spiral
Turn, and axially promoted along helical axis, realizes the quantitative conveying of material, pass through the revolving speed of rotating electric machine, spiral spacing and feed
The size of pipe can calculate or be determined by experiment delivery rate.The method is suitable for the rough feed of a large amount of powders, can not
Guarantee feed precision.Currently, having developed the screw feeder system of integrated Weighing system and frequency control motor, i.e. basis in the market
Powder weight required for process units and feed time calculate charging rate, preset motor speed, pass through the reality of Weighing system
The gap of numeric feedback practical charging value and theoretical values is surveyed, then motor speed is adjusted to control charging speed by frequency conversion frequency modulator
Degree keeps practical charging value and theoretical values close as far as possible.The deficiency of the method is that feeding system precision is not high, energy consumption is high, place
The problems such as managing low efficiency.
In the experiment of modern industry, lab scale and pilot process, it is often necessary to the process of industrial time production is imitated, to guarantee
The accuracy and reliability of experimental data, it is necessary to which accurate, continuous, even feeding, at present laboratory and scientific research are carried out to powder
Institutes is also usually fed using manual weighing, short cycle, multiple manual intervention mode.
Summary of the invention
In order to solve these technical problems, a kind of the present invention provides powders continuous, uniform, accurate charging gear leads to
It crosses using the design of cleverly structure, high-precision weighing sensor type selecting and control unit setting, while solving with small vibration, smart
The technical issues of really weighing and continuous uniform are fed several aspects.The technical solution adopted by the present invention is that: a kind of powder is continuous, equal
Even, accurate charging gear, including weighing sensor 1, pedestal 2, collector 3, feed hopper 4, dispenser 5, bracket 6, shaft coupling
7, driving device 8, control unit 9, it is characterised in that: feed hopper 4, dispenser 5, bracket 6, shaft coupling 7 and driving device 8 are installed
On the top of pedestal 2；1 one end of weighing sensor is mounted on the lower part of pedestal 2, and the other end supports collector 3.Weighing sensor 1
Arrangement quantity on pedestal 2 is 1~8.Current rewinding weight is transferred to control unit 9 in real time by weighing sensor 1, control
Unit 9 obtains current rewinding weight and carries out the revolving speed of control driving device 8 after data processing, and driving device 8 passes through shaft coupling 7
Dispenser 5 is driven to rotate.
Detailed description of the invention
Attached drawing 1 is schematic structural view of the invention.In figure: 1- weighing sensor, 2- pedestal, 3- collector, 4- feed hopper, 5-
Dispenser, 6- bracket, 7- shaft coupling, 8- driving device, 9- control unit.
Specific embodiment
Below in conjunction with attached drawing 1, elaborate to the present invention.As shown in Fig. 1: pedestal is the basic branch of whole device
Support frame frame, collector are placed on the bottom of pedestal, collect the powder material fallen from feed hopper.Control unit can independently be put
It sets, can also be fixed on the base.1 ~ 8 high-precision weighing sensor is arranged in the bottom of pedestal, weighing sensor it is more,
Precision is lower, considers from stability and accuracy synthesis, and arrangement 2~3 best.Feed hopper and bracket are mounted on the top of pedestal,
Driving device is fixed on bracket center, and is connect with dispenser by shaft coupling.
Powder material is contained in feed hopper, and when driving device driving dispenser rotation, powder material will be dropped into uniformly
In collector, due to there is powder to enter collector, the weight value that control unit obtains in real time from weighing sensor will change, control
Unit processed can be compared according to the changing rule of weight value with preset value, and the theoretical rotational speed value for then obtaining driving device is concurrent
Driving signal out, to realize accurate feeding.
Driving device can be realized using modes such as stepper motor, servo motor, magnetic drives, while can also be used and be subtracted
Fast machine increases torque.
Control unit can be using PLC or single-chip microcontroller as data processing module, using touch screen or instrument or PC conduct
Human-computer interaction interface.
By described above it is found that obtaining real-time weight value using high-precision weighing sensor, control unit realizes data
Processing, dispenser realizes even feeding, final to realize the continuous, uniform of powder, accurate feeding.
