Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic spinning, in particular to an electrostatic spinning device. Background Art

[0002] Electrospinning is a technology that uses electrostatic field forces to produce nanofibers. Its principle is that in a high-voltage electrostatic field, a charged polymer solution forms a Taylor cone under the action of the electric field force. When the electric field force is large enough, the charged droplets overcome the surface tension to form a charged jet, which is finally deposited and solidified on the collection mechanism to form a nanofiber structure. At present, the electrospinning method is the simplest and most cost-effective method for producing nanofibers, and the prepared fibers have the characteristics of small diameter, large specific surface area and high porosity. Therefore, it has a large application in many fields, such as the filtration industry, electronics, energy, catalysis, biomedicine and other fields, and has broad application prospects.

[0003] For example, the patent document with application number CN202220591682.8 discloses an electrospinning device, which arranges at least one of the isolation devices to be able to deflect around a first axis, and the first axis is parallel to the receiving surface, so that the deflection of the isolation device can drive the spinning mouth to move, and then the boundary position of the receiving area is moved, so that the range of the receiving area can be adjusted to adapt to receiving devices of different sizes, which can make the electrospinning device more versatile and avoid the need to cut and / or splice the receiving device when the range of the receiving area does not match the size of the receiving device, which can reduce the workload and reduce the loss of raw materials in production.

[0004] However, the existing electrospinning devices similar to the above documents still have the following shortcomings:

[0005] The distance between the nozzle and the receiving device and the spray angle of the existing device are not easy to adjust, which makes it difficult to adapt to different types of fiber production work and difficult to meet the needs of a certain field for fiber membranes. In addition, although the existing device can adjust the boundary position of the receiving area through the isolation device, as the isolation device tilts, its isolation effect will be affected, and the adjustment range is relatively limited.

[0006] Therefore, it is urgent to improve this shortcoming. The utility model studies and improves the existing structure and shortcomings, and provides an electrospinning device. Utility Model Content

[0026] The specific operation is as follows: the plate 1105 is driven to translate by the electric push rod 1104, so that the second rotating shaft 1103 slides along the arc groove 1106, thereby driving the connecting member 1101 to rotate around the first rotating shaft 1102, and then driving the mounting seat 12 and the electrode wire 13 to tilt, so as to adjust the inclination angle of the coating nozzle 14.
