一种软包装凹版印刷机带回风主、支管道的烘箱快干装置
By introducing an airflow circulation system consisting of a supply fan and a return fan into the oven's fast drying device, and combining this with an adjustment mechanism to regulate the airflow direction and intensity, the problems of insufficient air intake and uneven air pressure distribution were solved. This achieved efficient drying and optimized energy consumption, prevented film deformation, improved drying efficiency, and shortened the drying cycle.

AI Technical Summary
Existing oven-drying devices suffer from problems such as insufficient air intake and low return air efficiency, resulting in prolonged drying cycles, reduced drying efficiency, and increased energy consumption.
An airflow circulation system employing both supply and return air fans directs airflow onto the printing film through air knife nozzles and branch ducts. Combined with an adjustment mechanism, the airflow direction and intensity are regulated to form an inlet chamber and an outlet chamber, achieving uniform airflow distribution and circulation.
It improves the problems of insufficient air intake and uneven air pressure distribution, avoids film deformation caused by uneven temperature, improves drying efficiency, shortens the drying cycle, and balances the contradiction between drying efficiency and energy consumption.
