Automatic batching and weighing system system Now, along with the development of science and technology, Automatic batching and weighing system has been widely used in metallurgy, coal, chemicals, building material industry, etc. Automatic batching and weighing system can be set according to the input ratio and flow control of material flow, thereby achieve control of product quality and yield of the objective is to realize the automatic production process, and intelligent, enterprise's scientific management, safe and stable production and energy consumption is the important technical means. Computer control system in the production of ingredients used not only can improve the yield and quality ingredients and greatly reduce the labor intensity, and post to improve production efficiency.

Belt batching system is a continuous totalizing automatic weighing instrument. It has played a critical role in coal, chemical industry, metallurgy, building materials, food and other sectors that are crucial to national economy and people's livelihood. The cumulative control of some mixed materials batching is realized by batching scale. This accurate cumulative control can cut down the cost of manufacture, improve the quality of the product and enhance the efficiency of labor.

Automatic batching and weighing system is a kind of integrating transportation, measuring, mixing in an online automatic weighing apparatus measured dynamic. This system consists of one or more ingredients belt scales, can show not only transient flow and total amount of conveyor belt, can also according to the value of the instantaneous flow deviation to adjust to the size of the feed to flow, constitute a closer setting control system, and achieve constant flow of purpose. Along with the rapid development of industrial production, electronic belt scale increasing demand of burdening system, was widely applied in a pan of metallurgy, power, chemical industry, food industry etc of process control. At the same time, along with the computer technology and the rapid development of the automatic control technology, the system application technology more advanced, more extensive, field can take the scheme is more

agile diversity, and, due to the system often costly, users of the actual conditions are also different. Therefore, careful, choose a reasonable, perfect, economic solution appears especially important

The structures of the belt scales ingredients consists mainly of transmission mountings, weighing transducer speed sensor, scale, active roller, driven roller, conveyor belt conveyors, drag, adjusting devices, equipment etc. When the scattered in conveyor belt scale body through the material on the weighing scale body, the speed sensor and sensor signal and the weight of millivolt belt speed pulse signal through the junction box to strap balance meter.

The overall design philosophy of the Automatic batching and weighing system of the belt is: Before the belt conveyer is put into operation, the settlement value of the flow of the supplies is established on the keyboard by the attenbant to carry on the belt. After the system is put into normal running, loading signal of the belt that the one-chip computer samples and the speed signal leaves, walk belt speed signal and belt instantaneous weight, unit of length is it can calculate out belt twinkling of an eye flow F of supplies to multiply (t) . The flow can be in charge of the number and show, offer the craft data to attenbant to consult in the twinkling of an eye. 8031 systems and then compare the actual value of the flow instead of the establishing value, calculate out controlling amount vi after PID regulates operation, and then change into the electric current and output the signal, and then enlarged and controlled leading the open angle of silicon controlled rectifier, realize regulating the function of the electricity electromechanical magnetism clutch excitation electric current of slippery difference, thus regulate the rotational speed of the slippery difference electrical machinery of executive body, enable transporting the flow of supplies on belts to stabilize in the adjacent place of settlement value as much as possible, have a good static index and dynamic performance.

Automatic batching and weighing system is widely applied in industrial and agricultural production and social life in all areas. Especially the metallurgy, coal,
