AI Technical Summary
Traditional infusion bag dewatering devices have problems such as dewatering blind spots, poor applicability, easy damage to the conveying posture, and high cost. Especially in high-speed conveying or multi-row parallel operation, it is difficult to effectively remove water stains on the surface of the soft bag and maintain stability.
Employing a double-sided three-dimensional airflow design and lifting components, the system utilizes an array of first and second air knives combined with a perforated conveyor belt to achieve efficient double-sided water removal from the infusion bag. The lifting components are adaptable to different models, ensuring stable conveying posture and reducing bag displacement caused by airflow.
It achieves efficient double-sided water removal from infusion bags, is suitable for various delivery postures, reduces production costs, and improves water removal effect and equipment stability, making it more versatile.
