Description

Technical Field

[0001] The invention relates to a spinning electrode, in particular to a reciprocating electrostatic spinning electrode. Background Art

[0002] Electrospinning technology is a polymer processing technology that forms ultrafine fibers under the action of a high-voltage electric field. The principle of electrospinning technology: First, the polymer solution or melt is charged with high-voltage static electricity of several thousand to tens of thousands of volts. The charged polymer droplets are accelerated at the Taylor cone pole of the capillary under the action of the electric field force. When the electric field force is large enough, the polymer droplets overcome the surface tension to form a spray stream. During the spray process, the solvent evaporates or solidifies, and finally falls on the receiving device to form a fiber felt similar to a non-woven fabric. Electrospinning technology can easily prepare polymer ultrafine fibers with a diameter of more than ten nanometers to several hundred nanometers. So far, nearly 100 kinds of polymers have been successfully used to produce ultrafine fibers through electrospinning. The resulting products have the characteristics of high specific surface area, high porosity and good three-dimensional effect. They have very broad application prospects in the fields of tissue biotechnology, textile engineering, medical and health care, and have received increasing attention from the scientific community.

[0003] From the principle of electrospinning technology, it can be seen that the spinning device of electrospinning affects the arrangement order and uniformity of the fibers in electrospinning, and plays an important role in the output and quality of the fibers. Therefore, the spinning device of the electrospinning equipment is one of the important factors affecting the production efficiency and fiber diameter distribution of industrial electrospinning.

[0004] The electrospinning device introduced in patent authorization announcement No. CN214142626U "An electrospinning device" includes at least one desktop electrospinning machine, each coating head is provided with at least one liquid supply hole, and the liquid to be coated is introduced into the inner cavity of the coating head through the liquid supply hole; an electrode steel wire, both ends of which pass through the inner cavity of the coating head to be immersed in the liquid to be coated; and a rotating mechanism, the coating head and the electrode steel wire are both loaded on the rotating mechanism, and the rotating mechanism can drive the coating head and the electrode steel wire to rotate along the circumference of the desktop electrospinning machine.

[0005] However, the above technical solution has at least the following defects: since the electrode steel wire passes through the coating head, the coating head will have some structures on the upper part of the electrode steel wire. During the spinning process, the coating head follows the transmission mechanism, and the components located in the upper area of ​​the electrode steel wire will repeatedly scratch the electrospun fibers, which will affect the spinning efficiency and cause some electrospun fibers to aggregate to form large fiber bundles. After the large fiber bundles are broken, they will attach to the electrospun fibers, which will inevitably lead to uneven spinning and uneven appearance and quality of electrospun products.

[0006] In view of the shortcomings of the prior art, technicians in this field urgently need to develop an electrospinning device to overcome the problems of uneven appearance and quality existing in the above-mentioned electrospinning devices. Summary of the invention
