Description of the drawings
Fig. 1 is the structured flowchart that a kind of premixed feed produces Automatic Burden Control System.
Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described further.Here it should be noted thatFor the explanation of these embodiments is used to help understand the utility model, but do not constitute to restriction of the present utility model.ThisOutward, as long as technical characteristic involved in the utility model disclosed below each embodiment does not constitute conflict each otherCan just be mutually combined.
A kind of premixed feed production Automatic Burden Control System is present embodiments provided, as shown in figure 1, the control systemIncluding proportioning machine mair motor, feeder motor, feeder valve motor, raw material cabin valve motor, frequency converter, material positionInductor, LOAD CELLS, PLC and PC, proportioning machine mair motor, feeder motor and feeder valve motor respectively withThe output end electrical connection of frequency converter, the input of frequency converter electrically connected with the output end of PLC, raw material cabin valve motor andPLC output ends are electrically connected, and material position inductor and LOAD CELLS are electrically connected with the input of PLC, and PLC passes through multirow string with PCMouth connection.
Raw material is stored in raw material cabin.When dispensing is needed, operating personnel set formula on PC, and instruction is sent outPLC is delivered to, and after PLC receives instruction, instruction is sent to the corresponding raw material cabin valve motor of the raw material in formula, by originalFeed bin valve is opened.Raw material is automatically fallen in weigher, and weighing information is uploaded to PLC by LOAD CELLS, is made by PLC and being sentencedDisconnected, when weighing weight reaches recipe requirements, PLC sends the instruction for closing raw material cabin valve to raw material cabin valve motor,Now raw material cabin valve closing.Material transport to feeder, the material position inductor arranged in the front of feeder are examined by transmission beltMaterial transport arriving signal being measured, signal being uploaded to into PLC, PLC to react and instruction is sent to feeder valve motorOPEN, feeder valve are opened.Raw material enters proportioning machine by feeder valve.During weighing, if weighing weightWhen amount is more than formulary requirements amount, PLC will send instruction to alarm of weighing, alarm equipment alarm of weighing.
Rotational speed detecting device and electric current measuring and calculating device are installed on proportioning machine mair motor.When the material inside proportioning machineWhen position inductor detects material information, which uploads information to PLC, and PLC responds, and sends instruction, frequency converter to frequency converterThe mair motor work of control proportioning machine.Rotational speed detecting device on proportioning machine mair motor and electric current measuring and calculating device, will be examined in real timeThe service data of the proportioning machine for measuring is uploaded to PLC, and PLC will be judged according to setting value.If the excessive PLC of electric current will be to changeFrequency device sends instruction, and control proportioning machine operation is slowed down.When no material in proportioning machine, PLC then sends to dispensing machine host and treatsMachine is instructed, so as to energy saving.
Rotational speed detecting device and electric current measuring and calculating device are installed on feeder motor.Rotational speed detecting device and electric current measuring and calculatingDevice can carry out monitor in real time to the working condition of feeder, and the data for detecting are uploaded to PLC, and these are counted by PLC againAccording to PC is uploaded, operating personnel can grasp the working condition of feeder by PC.
Current alarm is additionally provided with this control system, and is electrically connected with PLC output ends.The alarm of electric current report pointFor proportioning machine Main motor current alarm and feeder current of electric alarm.When proportioning machine Main motor current exceeds setting rangeWhen, PLC sends instruction, proportioning machine Main motor current alarm equipment alarm to proportioning machine Main motor current alarm；When feeder electricityWhen electromechanical stream exceeds setting range, PLC sends instruction to feeder current alarm, and feeder current alarm is reported to the police.
Rotating speed alarm is additionally provided with this control system, and is electrically connected with PLC output ends.Rotating speed alarm is divided into matches somebody with somebodyMaterial owner's motor speed alarm and feeder motor speed alarm.When proportioning machine mair motor rotating speed exceeds setting value, PLCInstruction, proportioning machine mair motor rotating speed alarm equipment alarm are sent to proportioning machine mair motor rotating speed alarm；When feeder motor speedBeyond setting value when, PLC sends instruction, feeder rotating speed alarm equipment alarm to feeder rotating speed alarm.Above in association with accompanying drawingEmbodiment of the present utility model is explained in detail, but the utility model is not limited to described embodiment.For thisFor the technical staff in field, in the case of without departing from the utility model principle and spirit, these embodiments are carried out manyPlant change, modification, replace and modification, still fall within protection domain of the present utility model.
