Automatic batching system A common weighing device that uses negative pressure to attract material into a weighing device for weighing. It can effectively improve production efficiency and product quality. During the weighing process, the pressure inside the container is lower than the external atmospheric pressure, so the material is attracted into the weighing container. When the material reaches the set weight, the weighing container will automatically stop attracting and complete the weighing process.
020-34563445The Batching system consists of a set of industrial management system, a set of PLC electrical control system, and N sets of single loop closed-loop control loop. Each closed-loop control loop consists of a spiral conveyor, a weighing display, a weighing sensor, a frequency converter and a field control box. There is also a communication interface with the host computer. Transfer to the speed control hopper scale, the weight signal to the weighing instrument. The weight signal of the load is calculated and processed by the weighing instrument to obtain the weight of the material, which is displayed on the weighing display.
Weighing instrument and variable frequency governor control screw conveyor speed to form a closed-loop control, weighing instrument built-in intelligent software regulator can set high, medium and low feed to ensure the accuracy of the ingredients. Three sets of output signals are used to control the frequency converter, and then control the feed speed of the screw Feeder, so as to achieve the purpose of accurate batching. The weighing instrument can set the feed amount manually, or the ratio can be set through the two-way communication between the computer and the instrument. Communicate with PLC through serial port. According to the actual process of batching process, the industrial computer reflects the running status of loading, batching, feeding and related equipment in the form of dynamic pictures. When there is an over-limit fault during operation, will appear Chinese alarm and start the alarm (sound and light), or stop the machine, or change the warehouse. can make control status analysis according to the running data. The dynamic batching process of the system is reflected by different color histogram. According to the operation data, the industrial computer can assign the ratio or the feeding amount, and truly reflect the state of the dosing. It also has other functions, such as class report, daily report, monthly report, annual report and other functions. It provides convenience for management.
