Details Introduction

Spiral electronic scale is a tool that uses a rotating spiral as a material propulsion and conveying tool, continuously conveying materials in a closed tube while controlling and measuring the conveying process. This series of spiral electronic scales has a reasonable structure, stable and reliable operation, good sealing, no dust flying, no leakage, a conveying length of 1-5.5 meters, high conveying efficiency, and easy maintenance. 

螺旋电子秤是以旋转螺旋作为物料推进输送工具,在密闭管道内连续输送物料,同时对输送过程进行控制与计量的设备。该系列螺旋电子秤结构合理、运行稳定可靠、密封性好,无粉尘飞扬与物料泄漏现象,输送长度可达 1-5.5 米,输送效率高且维护便捷。
 

Features /产品特点
1. Specially designed for measuring and controlling powdered materials. 

专为粉状物料的计量与控制设计
2. The feeding spiral has a unique stable flow structure, and the powder evenly sinks across the entire feeding port section, making it less prone to arching and material flushing. 

进料螺旋采用独特稳流结构,粉体可沿进料口全截面均匀下沉,不易起拱、冲料
3. The cycloidal pinwheel reduction motor ensures long-term stable operation. 

采用摆线针轮减速电机,保障设备长期稳定运行
4. The steady flow spiral adopts a variable pitch structure and an outlet overflow method, effectively solving the problem of material flushing (double tube steady flow is used for production>60T/H). 

稳流螺旋采用变螺距结构及出料溢流方式,有效解决冲料问题(产量>60 吨 / 小时时采用双管稳流)
5. The measuring spiral scale adopts a direct weighing structure with three high-precision sensors (tension), which successfully solves the error caused by lever weighing and greatly improves the measuring accuracy. 

计量螺旋秤采用三传感器(拉力式)直接称重结构,成功解决杠杆称重产生的误差,大幅提升计量精度
6. Adopting a digital acquisition module with an effective resolution of up to 1 million; Collection rate of 50 times per second; Annual drift less than 50PPM; The temperature drift is less than 50PPM.

Working Principle / 工作原理

Spiral electronic scales are divided into spiral electronic measuring scales and spiral electronic batching scales, mainly composed of spiral scale body, speed sensor, weighing sensor, signal transmitter, frequency converter (this configuration is not available for measuring scales), control regulator, motor and other parts.
螺旋电子秤分为螺旋电子计量秤螺旋电子配料秤两大类,主要由螺旋秤体、速度传感器、称重传感器、信号变送器、变频器(计量秤无此配置)、控制调节器及电机等部件构成。
When the spiral scale transports materials, the weighing sensor converts the weight of the material on the weighing section into a voltage signal and sends it to the signal transmitter. The speed sensor converts the measured rotation speed of the spiral blade shaft into a pulse signal and sends it to the signal transmitter as well.
当螺旋秤输送物料时,称重传感器会将称重段的物料重量转化为电压信号,并传送至信号变送器;速度传感器则把检测到的螺旋叶片轴转速转化为脉冲信号,同样发送至信号变送器。
The signal transmitter performs preliminary calculations and processing on these two signals, which are then converted into digital signals and transmitted to the control regulator through a standard RS-485 communication interface. The control regulator further processes and calculates the signals, and finally displays the instantaneous flow rate and cumulative flow rate of the material passing through the spiral scale.
信号变送器对两路信号进行初步运算处理后,将其转换为数字信号,通过标准 RS-485 通讯接口传输至控制调节器;控制调节器进一步处理运算,最终显示出流经螺旋秤物料的瞬时流量与累计流量。
