The side wall of the bottom plate 112 is provided with a hinge rod 114 at the end corresponding to the material pouring port, the bottom plate 112 is movably mounted on the bearing horizontal frame 111 through the hinge rod 114, and the bottom plate 112 is driven by the turnover mechanism 3 to turn over around the bearing horizontal frame 111 through the hinge rod 114.
The length of the bottom plate 112 is the same as the distance between the bottom plate 112 and the dry powder discharge port 5, the dry powder discharge port 5 is positioned right above the bottom plate 112, and the baffles 113 on the three sides of the bottom plate 112 and the dust-proof folding assembly 12 together form an enclosure for dust prevention.
The weighing assembly 2 comprises a plurality of pressure sensors 21 uniformly distributed on a bottom plate 112, and the pressure sensors 21 are used for measuring the weight of the received dry powder in real time.
In order to improve the accuracy of the dry powder weight measurement of the material receiving mechanism 1, the material receiving mechanism 1 is composed of a bottom plate 112 and a baffle 113 surrounding the three sides of the bottom plate 112, the baffle 113 can play a role in dust prevention and dry powder blowing, and the dust prevention folding assembly 12 is also one of the structures for dust prevention.
When the bottom plate 112 is in the horizontal position, when the dust-proof folding assembly 12 is unfolded, an enclosure ring for preventing dust flying is formed with the baffle 113, and when the bottom plate 112 is driven by the turnover mechanism 3 to be gradually turned over to the vertical state, the dust-proof folding assembly 12 is folded under the action of the pull rope 124, the end part of the pool groove 11 forms a side opening for transferring dry powder, and the dry powder on the bottom plate 112 is transferred from the side opening.
It should be noted that, in the present embodiment, the receiving mechanism 1 is provided as a reversible structure, and the main purpose thereof is: because this embodiment is mainly used for through the dry powder unloading weight in the detection fixed time interval, whether the dry powder ejection of compact workshop section that the reamer corresponds breaks down, along with the accumulation of dry powder, will surpass the loading range of pond groove 11 at last, like this, the dry powder will spill over from the pond groove 11, and finally influences the judgement to the dry powder unloading weight in the unit interval, consequently need will accomplish the dry powder transfer of a weighing cycle to carry out the judgement of next weighing cycle.
Therefore, as shown in fig. 4, the specific control management system 4 includes a data processing unit 41, a timing unit 42, a data receiving unit 43 and an alarm unit 44, wherein the timing unit 42 is used for counting the weighing cycles of the single completion of the weighing operation, the data receiving unit 43 receives the output signal of the pressure sensor 21 once every same time interval, and the data processing unit 41 establishes the curve relationship between the time point and the pressure value in each weighing cycle.
The data processing unit 41 regulates the alarm unit 44 to work according to the curve relation between the time point and the pressure value, and the data processing unit 41 regulates the turnover mechanism 3 to work to perform dry powder transfer processing when a weighing cycle is completed.
When weighing is started, a single weighing period is determined according to the dry powder loading capacity of the tank 11 and the small powder speed, the timing unit 42 starts timing when the tank 11 resets and the pressure sensor 21 detects that the dry powder falls, and in the weighing period, the data receiving unit 43 receives the output signal of the pressure sensor 21 once at the same time interval, determines the dry powder weight discharged by the reamer at the same time interval, and accordingly determines the curve relation between different time points and pressure values in the weighing period.
It should be noted that, since the dry powder on the reamer continuously falls, when the tank 11 is reset, the pressure sensor 21 should immediately detect the falling of the dry powder, at this time, the timing unit 42 starts to time, and if the timing unit 42 does not start to time beyond the set time, it is determined that the reamer is out of order, and the regulation and control alarm unit 44 starts to alarm.
When the weight of the reamer discharged in a set time interval is in a linear relation with the time point, after a weighing period is finished, the data processing unit 41 regulates and controls the turnover mechanism 3 to work to carry out dry powder transfer processing when the weighing period is finished, and when the turnover mechanism 3 is reset, the next weighing period is carried out.
Meanwhile, in order to further improve the accuracy of judging the powder blanking of the data processing unit 41 in the stage of stable powder blanking, in the embodiment, based on the weighing cycle completed circularly, the functional relationship between the time point and the pressure value in the weighing cycle is determined, that is, after the data processing unit 41 completes a plurality of weighing cycles circularly, the standard weights corresponding to a plurality of time points in one weighing cycle are predicted, the data processing unit 41 compares the standard weight at each time point with the actual weighed pressure value, and the data processing unit 41 regulates and controls the operation of the alarm unit 44 according to the comparison result.
When the actual weighing pressure values determined by the time points according to the functional relationship are far smaller than the standard weight, the quality problem of the reamer is caused, the blockage of the reamer and the fracture failure of the reamer are caused, and it is particularly noted that the method is suitable for the condition that the powder supply is stable, the blanking stability is determined directly according to the difference between the standard weight and the actual weight at the time points in one weighing period, and compared with the determination of the curve relationship between the time point and the pressure value in each weighing period, the method is more accurate, because under the condition that the blockage of the reamer is caused, the condition that the time point and the pressure value in the weighing period are in a linear relationship may exist, but the total blanking amount is reduced. Therefore, the embodiment improves the stability and accuracy of powder blanking weighing detection.
