As shown in figure 1: the device comprises a speed regulating motor 1, a hopper 2, a weighing sensor 3, a weighing area 4, a speed sensor 5, a displacement sensor 6, a belt 7, a driving motor 8,

transmitters

9, 10 and 13, an upper computer (namely a computer) 11 and a programmable controller 12.

2. Feeding/discharging unit

The selection of the feeding and discharging mechanism is determined according to the specific properties of the materials. The material is granular or blocky in shape structure, and a feeder with electromagnetic vibration is selected; the material form structure is a feeding machine in a spiral mode selected in a powder state. The latter scheme is adopted in the present example.

3. Electronic weighing unit

3.1 weighing mode: 1) the material has large viscosity, poor fluidity and large retardation by adopting a reduction method. At the beginning of the batch, the batch scale is now filled and the filled scale is tared to 0, and the negative value of the reduction in the discharge reading is the weight of the discharge. The present example employs a subtractive method.

2) The material has small viscosity and good fluidity and can adopt an incremental method. The feeding mechanism feeds the materials into an empty weighing hopper until the set weight of the formula is reached.

3.2 weight transmitter

This example employs a digital weight transmitter. The digital weighing transmitter adopts a split digital sensor and is added with various functions including calibration, tare processing and the like. The output of the digital weight transmitter has various choices, can weigh the net weight of the system, and simultaneously has a remote control function.

3.3 electronic weighing instrument

The intelligent weighing instrument is adopted in the embodiment, the intelligent weighing instrument can receive the signal of the sensor, complete the metering calculation and simultaneously receive the blanking amount setting signal of the control system, compare the weight data signal transmitted by the digital weight transmitter with the preset formula value of the digital weight transmitter, control the output state of each preset point through the comparison result and simultaneously convert the output state of each preset point into a relay contact form to be used as a batching control signal of the Programmable Logic Controller (PLC).

4. Dosing control unit

The batching control unit of the embodiment is a batching control system consisting of a PLC (programmable logic controller), a contactor/relay low-voltage control circuit and an upper computer (with a touch screen computer). The PLC is the core of the control of the whole batching system. The control flow chart is shown in figure 2.

In the embodiment, the weighing sensor transmits an analog signal to the digital transmitter, the intelligent pressure instrument processes the analog signal and transmits a weight signal to the PLC, and the PLC transmits received data to an upper computer program interface for displaying and monitoring; when automatic mixing and batching are carried out, an automatic control key is pressed down, the PLC starts a batching system feeding device through a relay/contactor control circuit, various materials required by the system are orderly added into the stirring device according to the original proportion in the PLC, and meanwhile, the real-time monitoring is carried out through data fed back by the transmission of the weighing sensor, the digital transmitter and the intelligent weighing instrument, and the on/off control is carried out on a feeding valve; after the charging process is finished, according to the preset material mixing delay time in the PLC, the PLC utilizes the low-voltage control circuit to open the stirring device, so that the materials are fully stirred. And then the PLC controls the sequential action of the discharging device to discharge materials from the stirring device and convey the materials to a tablet press or a packaging machine or a vacuum packaging machine for storage, thereby finishing the automatic batching and controlling the work of one period.

The main functions of the PLC program are as follows:

1) manual control: each control link can be independently operated, and a 'pause/continue' key can be allowed to be used, and each parameter of the batching system can be modified in a pause state;

2) automatic control: completing a complete cyclic control period of links such as feeding, stirring, discharging and the like; during the operation, only the 'pause/continue' key is controlled, and the 'manual' key is invalid, so that various batching parameters of the system cannot be temporarily modified;

3) setting zero: setting zero under the weighing condition, so that the display value is zero, and if the display information is wrong and exceeds the zero setting range, the zero setting action can not be carried out;

4) removing tare weight: under the condition of subtraction weighing, the displayed weight value can be deducted by taking the peeling key as the tare weight, and the original weight is recovered by clicking the key once again.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to this embodiment will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
