Abstract

The embodiment of the invention discloses a material control system. Based on the fact that the material control system comprises a feed device, a feed device motor frequency converter and a constant speed transmission belt, the material control system only comprises a weighing sensor and a controller, wherein the controller can calculate the instantaneous weight and cumulative weight of a load on the transmission belt according to data measured by the weighing sensor, and regulate feed amount of the feed device according to the instantaneous weight and cumulative weight of the load on the transmission belt. According to the material control system, a speed measurement sensor or an integrating meter are not needed to be arranged. All functions of the integrating meter are integrated in the controller in the current material control system. The amount of equipment of the material control system is decreased, the system cost is reduced greatly, the structure of the material control system is simplified, and the maintenance and calibration of the equipment are more convenient.

Description

technical field [0001] The invention relates to the field of industrial technology, in particular to a material control system. Background technique [0002] The material control system is used to control the feeding and transmission process of materials, such as figure 1 As shown, it includes feeding equipment 1, feeding equipment motor frequency converter 7, controller 6 and belt scales and other equipment, wherein the belt scale includes a transmission belt 2 for transporting materials, and a weighing machine arranged under the weighing surface of the transmission belt 2 A sensor 3 and a speed sensor 5, and an integrator 4 connected to the load cell 3 and the speed sensor 5 respectively. [0003] The load cell 3 measures the weight of the material discharged from the feeding device 1 to the transmission belt 2, and the totalizer 4 calculates the instantaneous weight and cumulative weight of the material on the transmission belt 2 according to the measurement data of the ...
