AI Technical Summary
Existing rod-shaped material screening devices use mechanical levers, which can easily cause mechanical damage to the surface of corn ears, affecting product quality.
The non-contact air-blowing sorting method is adopted. The air supply component controls the airflow of the air outlet to blow out the defective material from the corresponding outlet. The combination of multiple independent outlets and air outlets achieves accurate screening.
It avoids mechanical damage, ensures product quality, and enables precise screening of materials with different defects, thus improving operational convenience.
