On, stock bottle empty bottle weight information is sent to master control borad, master control borad record stock bottle empty bottle weight by weighing sensor；Will sampling
Bottle empty bottle is positioned on sampling weighing unit, and sampling bottle empty bottle weight information is sent to master control borad, master control by rapid weighing sensor
Plate records sampling bottle empty bottle weight.2）Place stock bottle and sampling bottle, liquid taken by start button, master control borad compare stock bottle weight with
Stock bottle empty bottle weight, if both weight are identical, stock bottle is considered as empty bottle, alarm equipment alarm, takes liquid end-of-job；Master control borad is read
Sampling bottle weight is taken, if sampling bottle weight is zero, is considered as no bottle and alarms, take liquid end-of-job；If stock bottle weight is more than original
Material bottle empty bottle weight and sampling bottle weight, which are not zero then to sample, to be continued, and wriggling pump work feeding, high-speed weighing sensor is read in real time
Sampling bottle gross weight is taken, master control borad calculates material weight in sampling bottle.3）Material is less than the first sampling amount in sampling bottle again when, peristaltic pump is with the
One sample rate works, and when material weighs to the first sampling amount in sampling bottle, the work of peristaltic pump reduction of speed, is taken with the second sample rate
Sample, when material weighs to the second sampling amount in sampling bottle, peristaltic pump is stopped at once, removes sampling bottle, first round sampling knot
Beam.4）Master control borad reads stock bottle weight, if material is again less than twice of the second sampling amount in stock bottle, alarm equipment alarm, if former
Expect that again more than or equal to twice of the second sampling amount, sampling continues material in bottle, starts the second wheel work.5）If be sampled as powder,
Use powder hopper and screw rod pump channel instead.
The present invention passes through the mutual cooperation between weighing sensor, rapid weighing sensor and master control borad three, master control borad
Verification is automatically performed according to gravity sensor and quick gravity sensor feedback information, when solving peristaltic pump long-time and taking liquid,
The shortcomings that pipeline is tired, and precision declines；By being realized to weighing for stock bottle with contrast without material alarm and clout early warning
Function；By weighing and contrasting to sampling bottle, no bottle alarm is realized, liquid is avoided and overflows without reason；By setting first
Sampling amount, the second sampling amount, the first sample rate and the second sample rate, when being nearly completed a quantitative liquid getting, peristaltic pump
Slow down, reduce and take liquid error；By closed-loop control, it ensure that solution will not be contaminated in proportioning.
