The screening and weighing system comprises a multi-stage screen 8 and a grading weigher 9, the multi-stage screen 8 is arranged below the second-stage weigher 7, and the multi-stage screen 88 is connected with the grading weigher 9 through a chute.
And a humidity sensor is arranged in the drying and stirring machine 5.
The first-stage weigher 4, the second-stage storage bin 6 and the grading weigher 9 are connected with a central control machine 10 through RS485 interfaces.
The system randomly samples by a sampler at the head part (middle part) of the adhesive tape machine and then enters a first-stage metering bin (the maximum volume of the bin is 10kg) through a chute, and a first-stage weighing device under the first-stage metering bin weighs the sampling weight required by the test specification and then enters a drying stirrer to be dried and uniformly stirred.
Weighing the required sampling weight of the grouped sampling by the secondary weighing device, then screening and selecting the aggregate of all levels of grading by the test screening system, and weighing the aggregate of all levels of grading by the screened and graded aggregate entering the tertiary weighing device through the chute. And finally, transmitting the data of each weighing device to a data acquisition module through 4-20 mm serial port communication, transmitting the data acquired by the data acquisition module to a PLC memory through an RS485 communication interface for storage, transmitting the data in the PLC memory to data processing software through Ethernet, and transmitting the test analysis result to an upper computer of a central control room through the Ethernet after the data processing software performs data statistical analysis.
The electric control principle is as follows:
after the upper computer sends out the automatic test signal, PLC automatic control sampler starts. Carry out weight monitoring to the sample that the sampler was taken by weighing system, after sample weight reached the required sample weight of standard, weighing system feeds back to the PLC signal, and PLC sends out stop drive signal to the sampler, stops the sampler. The automatic dry-mixing machine that sends into of sample that the sampler was got, PLC starts through several seconds interval back automatic control dry-mixing machine, dry humidity transducer spreads the interior dry and wet degree of mixer in the dry-mixing machine, when dry humidity reaches the regulation action value in the mixer, feed back to the PLC signal this moment, PLC receives after the signal, send the drive signal who stops dry-mixing machine, the relay action stops dry-mixing machine, PLC automatic control dry-mixing machine stops and opens the radial gate, put into automatic weighing device with the even sample of stoving stirring, automatic weighing device weighs sample weight this moment, sample weight data is gathered by data collector and is transmitted to the PLC memory, the data this time is stored to the PLC memory, PLC will do the numerical value calculation for the first time this moment, obtain the sample moisture content. Then opening of PLC control second grade feed bin radial gate, after the ejection of compact reaches the division weight that the standard required, send PLC with weight data by weighing sensor, by PLC control blowing radial gate closing, the sample that gets into screening plant this moment is required sample volume. After the step is finished, the PLC automatically controls the screening device to be started, the samples are screened and graded, and the screening device is automatically stopped after the screening device runs for 4 minutes. Obtaining the grading weight of each grade, collecting and recording the grading weight data of each grade, accumulating all the grading weights to obtain an accumulated value, recording the accumulated data, transmitting the accumulated data and the grading data of each grade to a PLC memory, finishing the collection of all the data, reading the data in the memory by the PLC, and performing corresponding operation to obtain the grading occupation ratio of each grade.
