AI Technical Summary

Technical Problem

Existing air curtain filters are prone to dust accumulation, affecting ventilation efficiency and equipment lifespan, and cannot adapt to the feeding requirements of different sizes of fern fiber.

Method used

The system uses a dual-head motor-driven drive shaft and cam mechanism to automatically knock and clean the filter screen. Combined with springs and support shafts, it enhances the dust removal effect. The system also releases ions through the ion generator to prevent static electricity. The adjustment mechanism can adjust the feed width and height to accommodate different sizes of fern root.

Benefits of technology

It effectively prevents dust blockage, extends the service life of the air curtain machine, ensures ventilation effect, prevents dust diffusion, and improves the versatility and adaptability of the equipment.
