[0002] In the production process of metal furniture, the metal workpiece bent and formed needs to be painted on its surface to ensure the appearance and corrosion resistance of the workpiece. Currently, workers usually hang the workpiece on a hanger during the painting process. After painting, a high-temperature baking equipment is needed to ensure the firmness and glossiness of the coating. However, during the processing of metal furniture, especially after the pre-treatment steps such as phosphating and washing, there is often a certain amount of moisture remaining on the surface and pores of the metal workpiece. Therefore, after the pre-treatment of the workpiece, the workpiece needs to be dried to dry the surface of the workpiece before using the spraying equipment to spray the surface of the workpiece. This avoids the ineffective contact between the coating and the metal surface during the spraying process due to the lack of timely removal of moisture from the surface of the workpiece, which reduces the adhesion of the coating. However, in the existing technology, two sets of heating and drying devices are needed during the process of drying the surface of the workpiece, painting the workpiece, and high-temperature baking after spraying, which increases the cost of equipment.
