This utility model relates to a drying device with a ventilation structure. The upper and lower support plates of its support frame are densely covered with ventilation holes, breaking through the airflow obstruction of traditional solid support plates. This allows hot air to circulate without dead zones within the drying chamber, directly acting on the upper and lower surfaces and internal gaps of the copper-clad laminate roll material. This ensures uniform heating of the roll material and avoids localized over-curing or incomplete drying.
