A kind of control method of above-mentioned accurate measuring device, the enabling side weighed using two-door multifrequency and pulsed high-frequency vibration
Formula controls emptying door blowing, comprising the following steps:
1, program setting: setting should claim value, thick title value, set the opening time and frequency values of two emptying doors；
2, weigh metering: metering starts, and control unit passes through the corresponding driving mechanism of two emptying doors of control according to setting value
Movement, realization control the opening and closing of corresponding emptying door, are slightly claimed, when weighing value is greater than or equal to thick title setting value,
Stop the work that the first emptying door corresponds to driving mechanism, the first emptying door is closed, and the movement of the second emptying door remains unchanged；
When weighing value, which is greater than or equal to, to claim value, stop the work that the second emptying door corresponds to driving mechanism, the second blowing
Door is closed, this weighing terminates, and after weighing hopper blowing, is recycled into metering next time and is weighed.
Specifically, the emptying door 3 and 5 of the present embodiment, one of them claims emptying door to be thick, another claims emptying door to be thin,
The present embodiment claims emptying door using the first emptying door 3 as thick, and the second emptying door 5 claims emptying door as thin, illustrates.Referring to figure
3 be the electrical schematic diagram of the utility model, and Fig. 4 is the control sequential figure of the present embodiment, the partial process view of Fig. 5 the present embodiment.
The present embodiment setting is slightly to claim carefully to claim to illustrate for blowing door switch 2 times in blowing door switch 1 time time, serial vein when in Fig. 4
The punching 1 i.e. time sequential pulse of the first emptying door 3, time sequential pulse 2 are the time sequential pulse of the second emptying door 5.
Initial two emptying door is closed state, initially enters thick title mode, and the first emptying door 3 and the second emptying door 5 are logical
It crosses and movement is opened and closed according to time sequential pulse, the first emptying door 3 is i.e. thick to claim emptying door carefully to claim blowing relative to the second emptying door 5
The low frequency time blanking of door big flow, the second emptying door 5 is small flow high frequency time blanking, and the two carries out slightly claiming blowing jointly, works as weighing
When being worth more than or equal to thick title value is set, claim mode into thin, controller is right by logical operation control the first emptying door 3 of stopping
The work of driving mechanism is answered, the first emptying door 3 is i.e. thick to claim emptying door to close, and the movement of the second emptying door 5 remains unchanged, lasting to carry out
The small flow blanking of high frequency time realizes accurate weighing to improve material metering accuracy.When weighing value, which is equal to, to claim value, stop
Only the work of the corresponding driving mechanism of the second emptying door 5, the second emptying door 5 are closed, this weighing terminates, after 2 blowing of weighing hopper, follows
Ring enters metering next time and weighs, and circuits sequentially, realizes material weighing.
Wherein, after material accurate measurement weighs, for weighing value greater than when should claim value, setting should claim value to be weighed certainly according to more
Dynamic adjustment should claim value that should claim to be worth as what is weighed next time, and when weighing value, which is again equal to, to claim value, and value should be claimed to restore initial
Setting value.
Enabling amplitude, that is, enabling gap size of emptying door is controlled by the size of opening time in the application.
Embodiment two
Referring to Fig. 6, the present embodiment and embodiment one the difference is that: in the control method of accurate measuring device, slightly
Under title mode, the first emptying door 3 is identical with the opening time of the second emptying door 5, frequency, is all made of big flow low frequency time blanking,
Convenient for the quick decentralization of material, measurement efficiency is improved.
When weighing value, which is greater than or equal to, sets thick title value, into when carefully claiming mode, the first emptying door 3 is closed, and second puts
Bin gate 5 is controlled by controller, is changed to small flow high frequency time blanking, is reached when should claim value, and the second emptying door 5 is closed, this weighing
Terminate.
After 2 blowing of weighing hopper, it is recycled into metering next time and weighs, when slightly claiming mode, two drain hoppers are all made of big flow
Low frequency time blanking, when carefully claiming mode, the first emptying door 3 is closed, and the second emptying door 5 becomes small flow high frequency time blanking, until claiming
Magnitude, which reaches, should claim to be worth, and circuit sequentially, and realize material weighing.
Embodiment three
Referring to Fig. 7, the present embodiment and embodiment one the difference is that: enter thin when claiming mode, the first emptying door 3 closes
It closes, the second emptying door 5 is controlled by controller, and opening time, amplitude and the frequency of the second emptying door 5 are with should claim value and weighing value
Between difference reduce and respectively correspond shortening, reduction and raising, with that should claim to be worth closer to weighing value, weighing accuracy is increasingly
Height, to effectively further increase accurate measurement effect.The corresponding contracting of opening time, amplitude and the frequency of second emptying door 5
The short, degree that reduces and improve is on can be premised on blanking.
Example IV
Referring to Fig. 8, the present embodiment and embodiment two the difference is that: enter thin when claiming mode, 3 He of the first emptying door
Second emptying door 5 is controlled by controller, and the opening time, amplitude and frequency of the two are with the difference that should claim between value and weighing value
Value reduces and corresponds to shortening, reduction and raising, and with that should claim to be worth closer to weighing value, weighing accuracy is higher and higher, thus effectively
Further increase metering precision and measurement efficiency.The opening time of the emptying door, amplitude and frequency be corresponding to be shortened, reduce and
The degree of raising is on can be premised on blanking.
Although example and having described the embodiments of the present invention, the common field technique personnel of ability are come
It says, it can be appreciated that under the premise of not departing from the principles of the present invention and spirit, the utility model might also say that there are many become
Change, modification, replacement and variant, the protection scope of the utility model is by claims and its equivalents.
