AI Technical Summary

Technical Problem

In the existing technology, PC black masterbatch hardens and clumps due to temperature drop during the process of being transported from the internal mixer to the extruder, and gets stuck in the single screw feed port, affecting production continuity and product quality.

Method used

Design a single-screw-based feeding device that uses multiple sets of arc-shaped heating elements evenly distributed along the axial direction to form a continuous heating zone. It is equipped with an independent temperature sensor and a water-cooling structure to ensure that the material temperature is stable within the optimal flow range. At the same time, a fixing mechanism and a sealing ring are used to prevent material leakage and vibration.

Benefits of technology

It achieves high efficiency and stability in material conveying, prevents clumping, ensures production continuity, reduces energy consumption by more than 30%, extends equipment life, and improves production flexibility and product quality.
