AI Technical Summary
Existing paper tube drying equipment suffers from severe heat loss and is prone to paper tube accumulation and jamming.
The system employs a combination of components such as a limiting frame, heating element, conveying element, and circulating pump to form a closed drying space and heat circulation system. The top opening is sealed by a top cover, and the circulating pump extracts and recycles hot air. The unloading motor and conveying motor control the conveying speed and position of the paper tube to prevent accumulation.
It effectively reduces heat loss, prevents paper tube accumulation and material jamming, and improves drying efficiency and quality.
