AI Technical Summary
Existing powder coating machines experience unstable powder flow rates and uneven powder supply when the equipment vibrates or the air source pressure fluctuates, which is especially problematic in high humidity or dusty environments.
A magnetic powder supply module is adopted, which uses the magnetic field generated by the electromagnetic coil to attract and guide the powder. Combined with a negative pressure fan and a stirring structure, it suppresses powder accumulation and sedimentation, and achieves the following technical solution for powder: By setting up the negative pressure fan 2, filtered gas can be drawn in through the pipeline to form airflow driving force. When the electromagnetic coil 301 is working, the magnetic field attracts and guides the powder, which counteracts the influence of external vibration and airflow disturbance and maintains a stable powder supply.
It achieves stable control of powder flow rate in high temperature, high humidity or dusty environments, with coating thickness error of less than ±5μm, and is suitable for spraying complex structures and adaptable to multi-variety small-batch production.
