TECHNICAL FIELD
[0001] The utility model belongs to the technical field of wrapping wire manufacturing, specifically relates to drying device for polyimide film wrapping copper flat wire. BACKGROUND
[0002] In the manufacturing process of polyimide film wrapping copper flat wire, first, the copper flat wire needs to be polished to remove surface impurities and lay a smooth foundation for subsequent steps. Then, water washing and cleaning are performed to remove copper powder and other particles and chemicals that may be left over from the polishing process, ensuring the purity of the copper flat wire surface. Subsequently, the copper flat wire is dried to avoid adverse effects on subsequent wrapping processes.
[0003] When drying the copper flat wire, the drying effect is generally achieved by blowing dry, with the fan directly blowing dry towards the copper flat wire to accelerate evaporation of moisture. However, the copper flat wire has multiple surfaces and the blowing range of the fan is limited, making it difficult to ensure uniform and sufficient drying of the entire copper flat wire. If comprehensive drying is required, at least two fans need to be symmetrically distributed to dry the copper flat wire, so that the copper flat wire is blown from multiple angles at the same time, achieving a more comprehensive drying effect. If further improvement of drying progress is required, more fans need to be set up to dry different areas of the copper flat wire simultaneously, which is costly and resource-intensive, with low resource utilization.
