Problems solved by technology

However, most of the existing electrospinning devices currently use a single capillary to produce filaments, and the spinning efficiency is low.
The emergence of high-efficiency spinning nozzles has greatly improved the spinning efficiency, but it still cannot meet the needs of industrialization, and the spun fibers are distributed in a circular shape, which is not conducive to the collection and further processing of spun fibers. In addition, many high-viscosity melts are cooled rapidly after reaching the nozzle, making spinning difficult

Embodiment Construction

[0017] The present invention, a novel one-frame electrospinning nozzle, adopts such as figure 1 The schematic diagram of the device shown mainly includes a connector 1 and a drainage core 2 for guiding materials. The redistributed annular balance groove 7, the straight frame 3 directly connected with the drainage core 2 by screws, the flat groove surface 9 on the straight frame 3 for material flow, and the heating for the straight frame 3 Rods 6 and temperature sensors 5 for determining the temperature of the material on the nozzle, protrusions 10 for distributing the melt or solution, and tips 11 for forming the filaments.

[0018] The spinning solution or melt flows from the drainage groove 8 to the straight frame 3. When the solution or melt is evenly distributed on the protrusion 10, after the electrostatic field is applied, multiple jet streams 4 will be formed on the tip 11.

[0019] figure 1 and figure 2 Among them, the radius of the drainage groove 8 is 1.5mm, the ...

Abstract

The invention discloses a novel straight-strut electrostatic spinning spray nozzle, which belongs to the field of electrostatic spinning. The novel straight-strut electrostatic spinning spray nozzle comprises a connecting piece, a drainage core and a straight strut, wherein the connecting piece is in threaded connection with the drainage core; the drainage core is in screw connection with the straight strut; a drainage groove for material flow and an annular balancing groove for material redistribution are formed on the drainage core; a straight strut groove surface for material flow is formed on the straight strut; and the straight strut is provided with an independent temperature control device for heating, and after molten liquid or melts are distributed on the straight strut uniformly and an electrostatic field is added, multiple strands of spraying streams are formed at the top end of the straight strut. The novel straight-strut electrostatic spinning spray nozzle improves the efficiency of melt-electrostatic spinning greatly, and optimizes the arrangement structure of spinning fibers.

Description

technical field [0001] The invention relates to an electrostatic spinning device, which belongs to the field of electrostatic spinning. Background technique [0002] With the heating up of nanotechnology, electrospinning method has become one of the current research hotspots because it can prepare nanoscale fibers. The electrospinning method has been recognized as the simplest and most effective method for preparing nanofibers. At present, more than 30 kinds of polymers have successfully prepared ultrafine fibers through this method, and the smallest diameter reaches tens of nanometers. Regarding the research results of electrospinning, the relevant literature has increased exponentially in recent years. Electrospinning has a history of nearly 100 years since its appearance, but this technology has not yet been industrialized. [0003] The principle of electrospinning is to apply a high voltage between the nozzle and the receiving device to form an electric field between t...
