Abstract

The invention discloses a device for preparing nanofibers by a differential split-flow centrifugal spinning method. The device mainly comprises a motor support, a high-speed motor, a coupling, a rotator, a continuous feed device, an infrared temperature sensor, a conveyer belt roller set, an electromagnetic heater, a roller bearing block, a rotator bearing, a spinning manifold, conveying cord fabric, a rolling device and a take-up device. The motor support is fixedly arranged on the bottom bin of the spinning manifold and is used for fixing the high-speed motor; the rotator is driven to rotate at a high speed by the high-speed motor through the coupling and the rotator bearing; the continuous feed device is fixedly arranged at the top end of the spinning manifold; a discharge hole of the continuous feed device is arranged at the upper end of the rotator in an eccentric way, and a small interval is kept between the discharge hole and the upper end of the rotator. By combining a fluid differential structure and a reinforced fluid reduced conical surface, the control on the reduced degrees and centrifugal forces of fluids with different viscosity is realized, and meanwhile, a simple and efficient solution is provided to batch nanofiber preparation of solution or melt by the continuous feed device, an indirect heating device and the continuous take-up device.

Description

technical field [0001] The invention relates to a device for preparing nanofibers by using a differential split flow centrifugal spinning method, which belongs to the field of spinning and forming. Background technique [0002] With the rapid development of nanotechnology, the demand for devices and processes for preparing nanofibers in batches is becoming more and more urgent, and the application research is becoming more and more prosperous.
