The anti-roll weighing sensor is accumulated through the junction box and transmitted to the weighing instrument, which displays the weight of the material in the current weighing in real time through A/D conversion. The displayed weight data is transmitted to PLC through serial communication, and the PLC compares the collected weight of the weighing module with the weight set in the touch screen (or computer) of the electronic scale to control the action of the whole reaction kettle. It adopts high-performance configuration software, has a complete Chinese interface, and has real-time data display, flow and temperature control curves, alarm and operation records, complete production reports and other management functions.
020-34563445The weighing module plays a very important role in the Batching system, as it can provide real-time feedback on the actual weight to the control system. The control system uses real-time weight data to achieve precise capacity determination. Simultaneously utilizing the automated proportioning of collected weight signals, employing data computation and automatic adjustment to ensure accurate measurement of weight signals. It has functions such as human-computer interaction, communication, display and storage, printing, and various related operation screens such as data and graphic display, status monitoring, data input, and information storage. Real time process data monitoring, simulation display of process flow, real-time data recording and viewing, operator permission setting, process parameter setting, setting of operation process event alarms, and switching between manual and automatic control can be achieved.
The core part of the weighing module is the CPU, which communicates with the modules installed on the rack through the rack backplane bus. Under the premise of hardware self-test, module installation inspection and program scanning are carried out, and I/O module values are stored and regularly updated. The analog module polls each module of the equipment and continuously updates each channel. After the program execution is completed, the results are directly input and output, and even if the HMI fails, it will not affect the normal operation of the system. At the same time, the weighing sensor has the functions of interlocking control of itself and surrounding systems, controlling the operation status of internal motors, various Feeders, baffles, material doors, measuring buckets and other components of the control system, detecting the operation status of the state sensor, real-time monitoring and alarm reporting of the on-site situation, timely transmitting the operation status of the system to the upper computer and accepting full supervision from the upper computer.
The weighing module comprises a base component, a sensor component assembled on the base component, and a pressure plate component connected to the sensor component. The weighing module is characterized in that the pressure plate component comprises an upper pressure plate and an adjusting screw connected to the upper pressure plate; The support plate is equipped with adjustment screw holes, and the adjustment screw columns are connected to the adjustment screw holes to adjust the relative distance between the support plate and the upper pressure plate. The support plate is set in a square shape, and the support plate includes a main board body mounted on the board and a screw hole plate fixed to the main board body. The adjustment screw hole penetrates the screw hole plate, and the main board body is equipped with a clearance hole set coaxially with the adjustment screw hole. The area of the main board body is larger than that of the screw hole plate, and the support plate includes four installation holes surrounding the adjustment screw holes. The adjustment screw columns are connected to the upper pressure plate in a spiral manner. The adjustment screw hole is equipped with a relatively set clamping surface, which is located between the upper pressure plate and the support plate. Adjust the pitch configuration of the screw to 1mm~3mm, and align the centerline of the screw with the pressure centerline of the sensor component. The sensor components are configured as cantilever beam sensors or column sensors, and there are at least three Weighing modules. The support plate is used to connect to the material container, and the support plate of each weighing module is independently adjusted to the same height. The sensor components are connected to the weighing instrument.
