Embodiment Construction

[0011] The present invention is described in further detail below:

[0012] The present invention proposes a centrifugal electrospinning device, which mainly includes a high-voltage power supply, spinning components, feeding components, temperature measuring components and receiving components, such as figure 1 shown. The high-voltage power supply (11) is connected to the continuously rotating liquid storage tank (7) through a spring (9), and the receiving part is a conductive receiving net (8) located on the circumference of the spinning part, which is mainly used to receive the fiber (3). The receiving part is installed On the device frame (10), the frame is grounded so that a high voltage electrostatic field is created between the spinning unit and the receiving unit. The spinning part consists of a motor (1), a transmission device (12), a coupling (13), a rotating shaft (14), and a liquid storage tank (7). The transmission device is composed of bevel gears to realize spee...

Abstract

The invention discloses a centrifugal electrostatic spinning device. The centrifugal electrostatic spinning device mainly comprises a high voltage electrostatic generator, a spinning component, a feeding component, a temperature measurement component and a receiving component, wherein the high voltage electrostatic generator is connected with the spinning component through a spring. The spinning component is composed of a motor, a drive device, a coupling, a rotating shaft and a liquid storage groove, and heated in an infrared mode. The feeding component is a small extruder and mainly provides polymer liquid for the liquid storage groove. The temperature measurement component is a thermocouple which is directly inserted into the liquid storage groove. The receiving component is a receiving net arranged on the periphery of the spinning component. The centrifugal electrostatic spinning device has the advantages that ultrafine of electrostatic spinning polyester fibers by a combined action of centrifugal force and electrostatic force is utilized, efficiency of electrostatic spinning is greatly improved, and mass production of the electrostatic spinning is promoted to achieve.

Description

technical field [0001] The invention relates to a centrifugal electrostatic spinning device, which belongs to the field of electrostatic spinning. Background technique [0002] With the continuous heating up of nanotechnology research, the application of nanofibers has become more and more extensive. Electrospinning, as a simple and efficient method for preparing continuous nanofibers, has attracted widespread attention of researchers. However, how to obtain a large number of fibers with a diameter of less than 500 nanometers has become a bottleneck in the field of electrospinning research. [0003] The basic principle of electrospinning is to use electrostatic force as traction force to prepare ultrafine fibers. So far, solution electrospinning has achieved mass production of fibers, but melt electrospinning still cannot produce fibers with a diameter of less than 500nm in large quantities. The present invention introduces centrifugal force on the basis of electrostatic f...
