The belt batching automatic weighing control system refers to a control and management system that uses various automatic control technologies to complete the corresponding production processes such as conveying, weighing, and proportioning of one or more raw materials. It is used for bulk material production batching and can provide information-based production management functions. The system plays an important role in improving production efficiency, quality, and management level in modern industrial production.
The reason why the automatic weighing control system for belt batching can play an important role in production batching and management relies on various advanced structural devices in the system. The structural composition of the system includes not only hardware but also software. A complete belt batching automatic weighing control system mainly consists of batching electronic belt scales, instruments, control cabinets, industrial control computers, and upper computer software systems.
(1) Ingredient electronic belt scale
The ingredient electronic belt scale automatically and continuously weighs, measures, and accumulates bulk materials passing through the belt, with the main function of conveying and measuring. The weighing part includes a weighing sensor, a weighing bridge, and a speed sensor. The weighing sensor detects the weight of the conveyed material, the weighing bridge is a force transmission structure, and the speed sensor detects the belt speed. In practical work, the belt scale uses a constant speed measurement method to change the material flow rate by adjusting the feeding speed.
(2) Instruments and control cabinets
The control instrument is the core of weighing and control processing operations, receiving weight signals from weighing sensors and speed signals from speed sensors, calculating instantaneous flow and cumulative measurement, and having multiple functions such as data acquisition, status judgment, data processing, operation display, flow output, pulse output, standard communication, etc.
The instrument communicates with the industrial control computer through an interface, and transmits the flow signal to the industrial control computer. The industrial control computer compares the flow signal with the system set value and controls the speed of the on-site feeding motor to achieve the purpose of controlling the flow rate of a certain material, that is, to achieve quantitative feeding.
Multiple instruments can be centrally installed in the control cabinet for convenient on-site management and operation.
(3) Control device
The control device of the belt batching automatic weighing control system includes software and hardware, including electrical control cabinet, operation box, actuators, etc. The system relies on PLC to complete quantitative control. As the upper computer, the industrial computer can be connected to the PLC through a communication interface to control the operation mode of the PLC and output switch control signals to control the start and stop of the belt motor.
The main functions of the monitoring software include: automatic control of the weighing process based on production formulas and output targets, and calculation of frequency converter adjustment and control.
(4) Upper computer software system
The upper computer software system includes monitoring software, which can view on-site production ingredient data, equipment operation data, fault and abnormal record information, set formula parameters, etc. The software system interface adopts a menu style, with simple and convenient operation, to control and manage the entire ingredient system.
The design structure of Guonuo Technology's belt batching automatic weighing control system is reasonable, and the software and hardware modules are reasonable. It is customized according to the actual production process needs of users, providing efficient and accurate batching while improving the level of management informatization.
