Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic spinning production, in particular to an assembled needle-free spinning head device. Background Art

[0002] The rotating spinning head refers to the lower part of the spinning electrode immersed in the solution in the solution tank, and the solution is brought to the upper spinning area by the rotation of the spinning electrode, and a jet is generated under the action of the high voltage electric field to perform electrostatic spinning. The cover plate on the solution tank is used to seal the solution tank. The fewer the openings, the slower the solvent evaporates and the more stable the solution.

[0003] The cover plate on the solution tank has two sizes of openings. The long holes allow the spinning electrode to pass through, and the slits allow the spinning electrode connecting rod to pass through. The slits correspond to the connecting rods one by one. When the spinning head rotates, two rows of long holes are required, one row for the spinning electrode to rotate into the solution tank, and the other row for the spinning electrode to rotate out of the solution tank.

[0004] The existing rotating spinning heads are all integral, and the rotating shaft and spinning electrodes cannot be disassembled. As a result, in actual use, there will be multiple rows of spinning electrodes on the spinning head. In order for the spinning electrodes to pass through the cover plate for installation, it is usually necessary to open more than 3 rows of long holes on the cover plate, otherwise the spinning cannot be installed through the cover plate. If there are too many openings, more solution will be exposed to the air, resulting in faster solvent evaporation and accelerated deterioration of the solution. At the same time, the spinning electrodes on the spinning head can only be parallel to the rotating shaft. Other angles require larger holes in the cover plate to allow the spinning head to be installed. The number of rows of spinning electrodes on the spinning head cannot be too many, otherwise the cover plate will have too many holes and lose its sealing effect.

[0005] Based on the above reasons, the utility model provides an assembled needleless spinning head device. Utility Model Content
