【正文】 制約著整個生產的產品質量和產量，因此應對配料過程的質量和產量控制給予足夠重視。當散落在輸送皮帶機上的物料通過秤體時，秤體中的稱重傳感器和測速傳感器分別把重量毫伏信號和帶速脈沖信號通過接線盒送往皮帶秤儀表自動配料系統的總體設計思想為：皮帶輸送機投入運行前，輸送皮帶上物料流量的設定值由操作人員在鍵盤上設定。微機配料控制系統在生產中的應用不僅可以提高配料質量和產量，也大大減輕了崗位工人的勞動強度，提高了生產效率。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 puter 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 importantThe 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 onechip puter 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 pare 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 differenc
