Embodiment Construction

[0011] The vacuum centrifugal electrospinning device proposed by the present invention mainly includes eight devices of transmission, feeding, heating, sealing, spinning, collecting, temperature control and box. Firstly, the spinning device (2) is connected to the high voltage positive electrode, and the insulating collecting plate (19) is connected to the high voltage negative electrode, so that a stable electric field is formed between the spinning device and the collecting device. Determine the required spinneret diameter, use the plugging needle ( figure 2 ) to block unneeded spinnerets. Connect to the power supply, turn on the infrared thermometer (18), close the door of the vacuum box, and lock the locking buckle (1-1); the gas inside the vacuum box (1) is drawn out from the exhaust port (1-2) to ensure the vacuum Spend. When the pressure indication is stable, start the servo motor (4) to drive a pair of gears to move, the large and small gears (5, 13) drive the hollow...

Abstract

The invention discloses a vacuum centrifugal static spinning device, which mainly consists of eight major systems including a transmission system, a feeding system, a heating system, a sealing system, a spinning system, a collecting system, a temperature control system and a box body system, and is used for melt or solution centrifugal electrostatic spinning. The transmission system drives a yarn spraying device to rotate at a high speed, a receiving device is connected with a high-voltage power supply, the heating device heats polymer particles, a melt is stored in the yarn spraying device, an infrared temperature measuring instrument measures the temperature through emitting infrared rays and feeds back the result to the heating system for controlling the spinning temperature, under the effect of centrifugal force and electrostatic force, the melt is spun out, and nanometer level fiber is formed on the collecting device. In the whole spinning process, a transmission device, a feeding device and a magnetic fluid sealing device are positioned in a protection box body, the heating device, the yarn spraying device, the collecting device and a temperature control device are positioned in a vacuum box. The vacuum centrifugal static spinning device has the advantages that no disturbance of jet flow in vacuum environment can be ensured, and the goal of more stably preparing high-performance and high-quality nanometer fiber is achieved.

Description

technical field [0001] The invention belongs to the research field of electrospinning, and in particular relates to a centrifugal electrospinning device in which a spinning device and a collecting device are both located in a vacuum box. Background technique [0002] Nanofibers have good properties and can be widely used in medicine, filters, sensors and daily life. At present, the preparation methods of nanofibers include: wet and dry spinning, electrospinning, centrifugal spinning, molecular spinneret spinning, laser high temperature burning spinning, etc. Electrospinning is considered to be the most effective method for producing large quantities of continuous nanofibers due to its simple device, convenient operation, and low cost. Electrospinning is divided into solution electrospinning and melt electrospinning. Solution electrospinning has been widely studied because of its mild conditions, simple equipment, and fine fibers. However, the spinning efficiency of this m...
