Description

Technical Field

[0001] The utility model relates to the technical field of sheet material processing, and specifically, is a sheet material drying device. Background Art

[0002] Sheets may absorb or adsorb moisture during production and processing. For example, copper foil needs to be immersed in the plating solution during electroplating. Whether it is metal sheets, plastic sheets, paper sheets or wooden sheets, the presence of moisture may have a negative impact on their subsequent processing or performance. Drying can effectively remove free water and some bound water inside and on the surface of the sheet, preventing problems caused by sudden evaporation of moisture due to heat during subsequent processing, ensuring good physical and chemical stability, optimizing processing performance, meeting specific application requirements, and preventing various quality problems caused by moisture.

[0003] In the current existing technology, the drying device for sheets generally uses an integrated oven with multiple sections of heating tubes or heating rods that use heat radiation to achieve drying. After drying, an air cooling device is used for cooling. This structure has high energy consumption, low thermal efficiency, and occupies a large area. It is also unable to dry both sides of the sheet. At the same time, the structure of the integrated oven is not conducive to the subsequent maintenance of the equipment, resulting in an increase in the cost of sheet production and processing.
