Embodiment

[0033] In this embodiment, the electrospinning rotary spinning device, such as figure 1 As shown, it includes a micro injection pump 7 , a syringe 6 , a bearing sleeve 5 , a bearing 4 , a needle 2 , a receiving plate 1 and a high voltage power supply 11 .

[0034] Injection tube 6 is arranged on microinjection pump 7 by clamp, as Figure 4 As shown, the bearing sleeve 5 has a stepped inner cavity, which includes a bearing connection cavity 51, a transition cavity 52 and an injection tube connection cavity 53 arranged in sequence. The inner diameter of the bearing connection cavity 51 is larger than the injection tube connection cavity. The inner diameter of the cavity 53, the transition cavity 52 is an inner cavity formed by the smooth transition from the bearing connection cavity 51 to the injection tube connection cavity 53, and the smooth transition protrudes outward, and the bearing sleeve 5 is used to connect the bearing 4 and the injection tube 6 , the inside of which i...

Abstract

The invention relates to an electrospinning rotary spinning device and a method of using the same, comprising a micro-injection pump, an injection tube, a bearing sleeve, a bearing, a needle, a receiving plate and a high-voltage power supply. The advantages of the present invention lie in: the electrospinning rotary spinneret device and its using method of the present invention, the tail of the needle head is connected with a bearing, the bearing rotational frictional resistance is small, and the bearing is easy to be replaced after wear; the needle tube in the device is divided into equal volumes. Several layers, each layer of spinning solution is under the same pressure to ensure the uniformity of spinning; the speed of the needle is controlled by the motor, and the speed can be adjusted according to the characteristics of different polymers, so as to change the degree of spinning of the fibers and improve the product quality. quality.

Description

technical field [0001] The invention belongs to the technical field of electrospinning, in particular to an electrospinning rotary spinneret and a using method thereof. Background technique [0002] Electrospinning has become one of the main ways to prepare nanofiber materials due to its simple manufacturing equipment, low spinning cost, variety of spinnable materials and controllable process. Electrospinning technology can directly and continuously prepare polymer nanofibers. It has the advantages of low equipment and experimental costs, convenient, simple and flexible operation, and high fiber yield. The fiber membrane prepared by electrospinning technology has high porosity, Network structure with large specific surface area. [0003] The potential application value of nanofibers provides a new development space for the development of its preparation technology, and also puts forward new requirements. However, nanofibers prepared by electrospinning technology are relati...
