The weighing automatic logic Feeding machine completes the automatic and manual proportioning control of materials such as powder and liquid. Mixing powder and slurry simultaneously results in fast mixing speed. The feeding sequence can be adjusted arbitrarily to meet the process requirements. Theoretical calculation and manual correction of formula. The graphical interface displays the ingredient working conditions, making the operation intuitive. Implement the recording, printing, and report generation of proportioning data. Automatic and manual control for arch breaking. Intelligent diagnosis of wiring faults in Weighing modules, accurate positioning of faulty weighing modules and wiring, and automatic tracking of tare weight. Remote data browsing and printing. Temperature and pre curing temperature are automatically controlled. When all materials are added to the mixing kettle for reaction, due to the chemical reaction, a certain amount of time and temperature are required. The automatic feeding system automatically controls the temperature of the kettle mixture. When it is lower than the production process control temperature, the system sends an instruction to open the solenoid valve of the steam pipe to add steam. When the set temperature is reached, the solenoid valve is automatically closed (optional). The system is easy to expand.

The measurement of powder is stored in the raw material warehouse above the batching building, and a pneumatic disc valve is installed at the bottom of the warehouse. The outlet of the disc valve is connected to the spiral Feeder, and the outlet of the spiral feeder is flexibly connected to the batching hopper scale. The measurement of powder adopts the cumulative measurement method. Measure the powder in sequence according to the requirements of the process flow and formula. The metering and mixing of powder liquid and slurry are concentrated and qualified in the kettle, and then pumped into the slurry metering tank. The system achieves automatic measurement of slurry by controlling the start and stop of pumps and slurry motors. Add automatic tracking and compensation components to the system software design. According to the switch characteristics, the "pre closing" advance amount is automatically adjusted. The feeding system is turned off in advance before the material weight reaches the target value. After the weighing value stabilizes, the system automatically adjusts and replenishes the material based on the difference between the set value and the actual ingredient weight to ensure the accuracy of material measurement. To avoid interference signals from the weighing module signal, a low-pass filtering circuit and a power DC/DC isolation circuit have been added to the hardware circuit to minimize electromagnetic interference and impact. On the software side, VC is used to develop the underlying data acquisition thread, and oversampling and digital filtering algorithms are adopted to eliminate illegal sampling values and ensure the accuracy of the measurement circuit.

The weighing instrument can effectively prevent interference from the mains power frequency signal. The MODBUS fieldbus digital transmission method is used between the weighing instrument and the system to completely eliminate errors generated during the transmission process. At the same time, the adoption of fieldbus makes it very easy to expand the system, which can be expanded at any time according to future production needs without increasing significant costs. After the mixing kettle is prepared according to a certain ratio, it is added to the mixing kettle for stirring, and the temperature of the mixture is raised by injecting high-temperature steam. The temperature of the mixture directly affects the quality of the finished material. Therefore, an electric valve is installed on the steam pipeline and a mobile temperature Measurement system is installed next to the mixing kettle. The system measures the temperature of the mixing kettle in real time and automatically closes the steam valve when the temperature reaches the set value. This can ensure product quality and prevent energy waste caused by delayed valve closure, which helps to reduce production costs of the product.

The mixing kettle adopts a digital temperature measurement IC to measure the temperature inside the mixing kettle tank. The weighing terminal is connected to the data transmission radio through a data cable, and the temperature data is sent to the data transmission receiver of the Batching system. The system is connected to the receiver through a communication interface to obtain the real-time temperature of the kettle and display it on the system screen in real time. At the same time, the system controls the opening and closing of the steam charging electric valve according to the temperature. The statistics and remote storage of ingredient data are first stored in the local database of the ingredient system. The ingredients are equipped with standard Ethernet interfaces and connected to the enterprise management system through Ethernet cables. Generally, there will be a certain distance between the ingredients and the management office, with wiring exceeding 100m, which is greater than the allowable distance for Ethernet Category 5 cables. Therefore, installing a network switch between the ingredients and the management office can expand the effective connection distance to 160m and meet the needs of remote data sharing in the system. Due to the large amount of dust in the production environment of ingredients, printers and other equipment are prone to malfunction. Therefore, the printer equipment is placed in a management office with a relatively good environment, and the network printing function is used to realize the statistics, printing, and storage of production reports. The Sorting machine is equipped with production management and statistical software in the management office system.
