AI Technical Summary
Existing electrospinning collection devices suffer from problems such as nanofiber membrane deformation and uneven collection due to uneven solvent evaporation in large-scale industrial production. Existing solutions, such as edge warm airflow assistance, infrared heating baking, and dense exhaust devices, have limitations and cannot achieve uniform collection and morphology optimization of nanofiber membranes.
The design employs a combination of a collection conveyor belt, an exhaust unit, and a heating unit. By setting heating coils and heat transfer chambers on the collection conveyor belt, and combining them with a flexible isolation plate to divide the space into a control space, and using the exhaust device to create negative pressure, uniform desorption and evaporation of the solvent are achieved. Combined with the contact heat transfer of the heat transfer unit, uniform deposition of nanofibers is ensured.
This method achieves uniform collection and optimization of the macroscopic morphology of nanofiber membranes, avoids fiber membrane deformation caused by solvent accumulation, and improves fiber deposition efficiency and overall membrane uniformity.
