[0002] An electronic belt weighing device is a metering device used for automated and continuous weighing of bulk solid materials transported on a belt conveyor. It primarily consists of a load cell, a speed sensor, an instrument, and a scale frame. The scale frame defines the weighing section. As the material passes through the weighing section, the load cell detects its weight and generates a weight signal. The speed sensor provides a series of pulses proportional to the belt speed. The instrument receives the weight and speed signals, integrates them, and displays the instantaneous and cumulative flow values.

[0003] The existing electronic belt weighing device has gradually exposed its shortcomings during use, which are mainly manifested in the following aspects: the existing electronic belt weighing device has low adaptability and complex installation. Specifically, the belt conveyor models used for weighing different types of solid materials are different. The width and angle of the conveyor belts of different models of belt conveyors are different, and the height difference between the conveyor belt and the roller bracket and the width of the roller bracket are also different. However, the same model of electronic belt weighing device can only be adapted to a specific model of belt conveyor, so the adaptability is low, and the existing electronic belt weighing device is usually fixed to the roller bracket of the belt conveyor by welding. The welding process is not only complicated but also difficult to disassemble later.

[0027] The speed measuring roller 10 cooperates with the two adjustment components 9 to adapt to conveyor belts of different widths and angles.
