Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, specifically to a coating machine drying oven. Background Technology

[0002] As a core drying device in the coating process, the technological development of coating ovens closely revolves around coating uniformity, drying efficiency, and energy optimization. Traditional ovens mostly employ hot air circulation systems, using a combination of heating elements and fans to transfer heat. However, in multi-layer coatings or applications with heat-sensitive substrates, they often face problems such as uneven temperature gradients, excessive energy consumption, and limited drying rates. Early designs relied heavily on static air duct layouts, which can easily lead to localized overheating or airflow short-circuiting, affecting the uniformity of coating crystallization. In recent years, with the application of precision coating technology in fields such as new energy battery separators and optical films, ovens have gradually introduced zoned temperature control, gradient air curtain designs, and waste heat recovery technologies. Simultaneously, they incorporate non-contact heating methods such as infrared radiation and microwave-assisted drying to reduce the impact of thermal stress on flexible substrates. However, existing technologies still suffer from bottlenecks such as insufficient multi-stage drying coordination, lagging humidity control, and limited intelligence, hindering the industrialization efficiency of high-solids content slurries or ultra-thin coatings. Current research focuses on multiphysics coupling simulation optimization, machine learning-based dynamic temperature and humidity control, and the development of low-energy-consumption, fast-response heating modules to meet the dual requirements of high-speed coating production lines for precise drying processes and green manufacturing.
