Details Introduction

TDG speed regulating quantitative feeding scale is a dynamic weighing equipment produced by our company for continuous conveying, dynamic measurement, and controlled feeding of various block, particle, and powder materials (such as sand, limestone, coal, iron powder, clay, etc.). It can be widely used in industries such as cement, coal, metallurgy, chemical, building materials, grain, and feed. As a dynamic continuous metering and batching machine type automation control device, it provides accurate measurement data and control methods for production control and management in various industrial sites. 

本设备是我司研发的动态称重设备,适用于砂石、石灰石、煤炭、铁粉、黏土等各类块状、颗粒状、粉状物料的连续输送、动态计量与定量给料控制。可广泛应用于水泥、煤炭、冶金、化工、建材、粮食、饲料等行业。作为一款动态连续计量配料类自动化控制装置,它能为各工业现场的生产控制与管理,提供精准的计量数据与控制手段。

Working Principle
工作原理

The working mode of the TDG series speed regulating quantitative feeding scale is shown in Figure 1.

TDG 系列调速定量给料秤的工作方式如图 1 所示

The TDG series speed regulating quantitative feeding scale transports materials to the scale body through the material port regulator, and then completes the conveying measurement through the weighing section  of the scale body, with the belt speed regulation operation coordinated.

TDG 系列调速定量给料秤通过料口调节器将物料输送至秤体,随后经由秤体的称重段完成输送计量,同时配合皮带调速运行。

The series of feeding scales adopt a system structure where a set of measuring rollers is installed between two sets of cross spring plates, and the measuring and weighing roller is located at the center of the weighing section .

该系列给料秤采用的系统结构中,一组测量托辊架设于两组十字簧片之间,且测量称重托辊位于称重段的中心位置。

When there is no material on the belt scale body, the force applied to the weighing sensor is zero, that is, the tare weight  of the scale is zero (generally, the force applied to the weighing sensor is slightly greater than zero, that is, the starting pressure ).

当皮带秤体上无物料时,称重传感器所受的作用力为零,即秤的皮重等于零(通常情况下,称重传感器所受作用力略大于零,即初始压力)。

When materials are transported from the feed port to the discharge port, the gravity  of the materials is transmitted to the force - bearing point of the gravity sensor. The weighing sensor detects the gravity of the materials and converts it into an electrical signal  proportional to  for instrument processing.

物料从进料口输送至出料口的过程中,物料重力会传递至重力传感器的受力点。称重传感器对物料重力进行检测,并将其转换为与成正比的电信号,供仪表进行处理。
