I. Product Overview

The belt scale quantitative feeder is an intelligent industrial conveying and metering device integrating continuous material conveying, dynamic precision weighing, and automatic quantitative batching. It is specifically designed for powdery, granular, and small lump bulk materials. Relying on high-precision dynamic weighing technology and a frequency conversion intelligent control system, the equipment can monitor the instantaneous flow rate and cumulative conveying volume of materials in real time, automatically calibrate and adjust the feeding speed, and achieve constant, uniform, and quantitative material conveying. This completely solves the industry pain points of traditional manual feeding, such as low accuracy, material waste, imbalanced proportions, and low production efficiency. It is widely applicable to various industrial automated batching production lines and is a core supporting equipment for refined production, energy saving, and intelligent management in industrial and mining enterprises.

II. Working Principle

The equipment consists of a weighing bridge, high-precision weighing sensors, speed sensors, a frequency conversion drive system, intelligent control instruments, and a frame belt system. During operation, the belt carries the material at a uniform speed. The weighing sensors collect the material weight signal in real time, and the speed sensors simultaneously capture the belt speed signal. Both signals are transmitted to the intelligent control system in real time. The system accurately calculates the instantaneous flow rate and cumulative conveying volume of materials through a core algorithm, and automatically compares it with preset batching parameters. It dynamically adjusts the belt speed in real time through frequency conversion speed regulation, dynamically correcting the feeding amount. The entire process is closed-loop controlled, maintaining stable material feeding accuracy at all times, achieving fully automatic, uninterrupted, and high-precision quantitative feeding operations. III. Core Product Advantages

1. Precise Measurement, Controllable Error

Equipped with high-precision weighing sensors and employing dynamic weighing verification technology, the dynamic measurement accuracy is stably controlled within ±0.5%~±1.0%, with even higher static accuracy, meeting industrial high-precision batching production standards. The equipment supports long-term continuous operation, with stable and drift-free measurement data, effectively ensuring the accuracy of material proportioning on the production line and improving finished product quality.

2. Frequency Conversion Speed Regulation, Wide Adaptability

Utilizing an intelligent frequency conversion speed regulation control system, the belt speed can be flexibly adjusted, and the feeding flow rate adjustment range is wide, supporting multiple quantitative output levels from 0.5-200t/h. Feeding parameters can be freely set according to production process requirements. Whether for small-flow precision batching or large-flow continuous conveying, it can be smoothly adapted to various production conditions. 3. Stable operation, leak-proof and spill-proof: The entire machine adopts a reinforced carbon steel powder-coated frame, with a stable structure, strong load-bearing capacity, and no shaking or deviation during operation. Equipped with a dedicated annular skirted rubber belt, it effectively prevents spillage, leakage, and dust generation during the conveying of powdery and fine granular materials, reducing material loss, improving the workshop production environment, and boasting a low equipment failure rate, allowing for 24-hour continuous operation. 4. Intelligent linkage, high degree of automation: Equipped with intelligent digital display control instruments, it intuitively displays real-time data such as instantaneous flow rate, cumulative output, and operating parameters, making operation simple and convenient. It supports 4-20mA analog signals and RS485 communication, seamlessly connecting to the factory's DCS automation control system to achieve remote monitoring, parameter adjustment, and data traceability, adapting to the production needs of modern smart factories. It also features a built-in fault alarm function, automatically alerting users to equipment malfunctions for timely troubleshooting and maintenance. 5.
