[0002] Electrospinning is a special fiber manufacturing process in which a polymer solution or melt is jet-spun in a strong electric field. Under the action of the electric field, the droplet at the needle tip changes from a spherical shape to a conical shape (i.e., a "Taylor cone"), and fiber filaments extend from the tip of the cone.

[0052] The present invention is based on Figure 6 , Fig.10 , Fig.11 The rotating pressing member 31 includes a connecting plate 45, a pressing rod 46, and a pressing rod pressing mechanism 47. The connecting plate 45 is hinged on the U-shaped frame 33. The pressing rod 46 is fixedly connected to the connecting plate 45 and pressed on the U-shaped pressing rod 44. The pressing rod pressing mechanism 47 is fixedly connected to the protruding end of the electric telescopic rod 27 and is slidably connected to the pressing rod 46.

[0053] The present invention is based on Fig.10 , Fig.11 , Fig.12The pressing rod pressing mechanism 47 includes a fixed support plate 48 and a driving block 49. The fixed support plate 48 is fixedly connected to the protruding end of the electric telescopic rod 27. A U-shaped groove 50 is provided on the fixed support plate 48. The driving block 49 is disposed in the U-shaped groove 50 and is rotatably connected to the fixed support plate 48. The pressing rod 46 slides through the center end of the driving block 49. When the electric telescopic rod 27 retracts, the fixed support plate 48 moves, driving the driving block 49 to move and rotate, thereby being able to press the U-shaped pressing rod 44 downward.

[0054] The present invention is based on Fig.13 A circular groove 51 is provided on the support seat 21, and a circular plate 52 rotatably connected to the support seat 21 is provided in the circular groove 51. The circular plate 52 contacts the end of the spinneret needle 8 opposite to the ejection end. The circular plate 52 is rotatably connected to the support seat 21 to facilitate full contact between the piston end of the spinneret needle 8 and the circular plate 52.

[0055] Principle of the present invention:

[0056] The spinneret needle 8 is placed between the lower pressure ring 41 and the upper pressure ring 42, and the electric telescopic rod 27 starts to contract, driving the fixed support plate 48 to move, and then driving the driving block 49 to move with the fixed support plate 48, and rotate while moving, so that there is a downward squeezing force on the pressing rod 46, and then the U-shaped pressing rod 44 is squeezed downward by the pressing rod 46, and then the U-shaped pressing frame 43 is squeezed downward, and then the upper pressure ring 42 is squeezed downward, and the spinneret needle 8 is fixed by the cooperation of the upper pressure ring 42 and the lower pressure ring 41.

[0057] During the process of fixing the spinneret needle 8, the electric telescopic rod 27 simultaneously drives the connecting circular plate 34 to move, and then drives the insulating plate 35 to move, so that the lead ring 36 moves with the insulating plate 35, so that the lead ring 36 is sleeved on the spinneret needle 8. When the lead ring 36 moves, it will drive the supporting round rod 38 to move in the moving groove 39. When the spinneret needle 8 is fixed, the supporting round rod 38 moves into the placement groove 40. The lower surface of the placement groove 40 is lower than the moving groove 39. Therefore, the supporting round rod 38 will fall downward, thereby driving the lead ring 36 to fall. When the lead ring 36 falls, it contacts the end of the spinneret needle 8 to achieve continuous conduction.

[0058] The above steps realize the fixing of the spinneret needle 8 and the connection between the spinneret needle 8 and the high-voltage power supply device 4.

[0059] Rotate the fixing bolt 20 to move up or down, thereby causing the rotating block 18 to rotate and the sliding block 19 to slide, causing the upper fixed support plate 15 to rotate around the rotating member 13, thereby achieving angle adjustment of the upper fixed support plate 15, thereby achieving angle adjustment of the spinneret needle 8.

[0060] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
