Description

Technical Field

[0001] The present invention relates to the technical field of nanofiber preparation, and particularly to a wire winding device for electrospinning. Background Art

[0002] The wire winding device for electrospinning is a key component for realizing the efficient collection of nanofibers. The rotating cylinder collector is the most common wire winding device. By rotating a metal cylinder or disk, centrifugal force is generated to evenly wind the fibers on the surface. During the electrospinning process, a high-voltage electric field (usually 10 - 30 kV) causes the polymer solution / melt to form a Taylor cone at the needle tip. The jet is stretched and refined under the action of the electric field force and finally moves towards the collector in the form of nanofibers. At this time, the collector acts as a grounded electrode, and the electric field distribution on its surface directly affects the deposition path of the fibers.

[0003] The existing publication number: CN211999991U. This utility model discloses an anti-tangling wire winding device for electrospinning. A first rotating rod is rotatably connected between the upper and lower inner walls of the left square frame. A guiding roller is rotatably sleeved on the surface of the first rotating rod, and a plurality of grooves are formed on the surface of the guiding roller. A multi-layer partition is arranged inside the right square frame, and each partition layer is provided with a cavity. Two rotating shafts are rotatably connected between the upper and lower inner walls of each cavity. Two first gears meshing with the same second gear are respectively fixedly sleeved on the corresponding rotating shaft surfaces. A wire winding cylinder is arranged between two adjacent trays on the same axis in one group, and a wire unwinding cylinder is installed between two adjacent trays on the same axis in the other group. The base tape is wound on the wire unwinding cylinder, and the end of the base tape passes through between the receiving device and the spinneret, then bypasses the corresponding groove on the guiding roller, and finally is connected to the wire winding cylinder. The receiving device is spherical, and the concave surface of the sphere faces the spinneret. It solves the problem that the existing electrospinning is prone to tangling during winding, which affects the product quality, and improves the production efficiency.

[0004] However, during the electrospinning process, when the rotating cylinder collector drives the fiber orientation deposition through the centrifugal force generated by the rotation speed, when the rotation speed exceeds the critical value, the centrifugal force will exceed the adhesion force (van der Waals force, electrostatic attraction) between the fiber and the collector surface and the electric field binding force, resulting in the "wire throwing" phenomenon where the fiber detaches from the collection surface. This phenomenon will significantly reduce the fiber deposition uniformity, cause deviation in the areal density of the nanofiber membrane, and affect the mechanical properties and functional consistency of the fiber products.
