High-precision spiral metering technology for spiral powder packaging machine

The spiral metering device adopts advanced variable frequency speed regulation technology, which can accurately control the speed of the spiral shaft, thereby realizing precise regulation of the powder material flow rate. By cooperating with a high-precision weighing sensor, a closed-loop control system is formed to monitor the weight change of the material in real time, and automatically adjust the speed of the spiral according to the preset packaging weight, ensuring that the weight error of each bag of material is controlled within a very small range.

The design of the spiral blade has been carefully optimized, using a special curved surface shape and spiral line equation, so that the material can be evenly distributed and stably discharged during the conveying process, avoiding the accumulation, blockage and impact of the material, and further improving the accuracy and stability of the measurement. At the same time, according to the characteristics of different materials, such as density, fluidity, hygroscopicity, etc., the precise measurement of various powder materials can be achieved by replacing spiral blades of different specifications and shapes, which greatly improves the applicability and flexibility of the equipment.
