AI Technical Summary

Technical Problem

Existing drying equipment for aluminum electrolytic capacitor production suffers from uneven hot air distribution, resulting in inconsistent drying effects and incomplete or excessive drying in some areas.

Method used

The design incorporates a tumbling assembly and uniform hot air distribution. Combined with a hot air blower and a geared motor, the rotating shaft is driven by meshing gears, causing the drum to tumble at a low speed. This ensures that the capacitors are tumbled in all directions within the placement chamber, and moisture is promptly discharged through the vents. The water collection tank collects the moisture, achieving all-around drying.

Benefits of technology

This method achieves uniform drying of all surfaces of the capacitor casing, improving drying efficiency and quality, reducing moisture residue, lowering labor intensity, and avoiding problems such as incomplete drying or capacitors becoming damp again due to moisture residue.
