An adjustable drying duct structure for packaging printing

An adjustable drying duct structure for packaging printing includes a drying chamber. The drying chamber has multiple hinges on its outer walls at both ends, each hinge having a door. Multiple air inlet valves are installed on the diversion pipe. The diversion pipe of this adjustable drying duct structure for packaging printing is connected to the drying machine's heating system via a first air inlet pipe, and to the drying ports via a first connecting pipe and air inlet valves. This allows control over the number of drying ports based on the drying chamber's operating status, ensuring efficient preheating while preventing excessive airflow that could lead to overheating. The fixed cover of the device has corresponding spiral holes, and a perforated plate is screwed to the fixed cover to form a spiral locking structure. This allows the perforated plate to filter hot air while facilitating periodic cleaning of the inside of the fixed pipe using its outer brush.
