The material tower Weighing system can monitor the changes in material weight in real time, convert it into data information through the weighing module and summarize it in the central processing unit, recording the material consumption at different stages of various production from the data level. Based on the weighing data of the material tower and combined with the growth curve of production, a more scientific batching method can be optimized to continuously improve the material conversion rate of production, enhance the output ratio of the entire industry, fundamentally achieve the digital improvement of the industry, and realize cost reduction and efficiency improvement in materials.

The material is stably fed into the material tower for weighing. It is carried from the discharge port by the wheel spoke spiral to the discharge port. The powder material falls freely under the effect of gravity. Before the material leaves the material tower for weighing, the system detects the speed signal of the spoke material tower weighing through a rotary encoder, collects the material mass signal through the weighing module, and at the same time adopts a feedforward scheme to store the screw load value in the control system. Before the material is discharged, it is compared with the set flow value of the system to control the frequency of the variable frequency speed regulation motor. This feedforward control achieves high-precision difference compensation, which can correct any fluctuations with high accuracy. After processing and calculation by the control system, the actual flow rate of the material is obtained. By adjusting the rotational speed of the spoke screw, stable and quantitative feeding of the material and high-precision measurement are realized.

The support structure of the material tower mainly consists of Weighing modules, sensor junction boxes, weighing instruments and other components. The weighing module is a new type of weighing unit formed by integrating high-precision sensors, load transmission devices and installation connection devices, etc. Through the material tower support structure of the weighing module, the screw conveyor operates within a complete cycle. When the material in the weighing material tower reaches the lower weighing limit position, the feeding equipment is activated (or an alarm prompts manual feeding) to add material. The material in the raw material bin is quickly lowered into the weighing material tower. When the set upper limit value is reached, it is closed. The weight reduction value of the material in the weighing material tower within a unit of time is detected Calculate the actual flow rate of the material. According to the set target flow rate, perform PID regulation on the frequency converter controlling the unloading equipment to achieve the control purpose of tracking the actual flow rate to the target flow rate. The accuracy and control precision of weighing have been improved by adjusting the blanking time and difference compensation points through the blanking rate.
