Problems solved by technology

[0003] However, existing nanofiber yarn production devices still have many disadvantages in actual use. For example, traditional electrospinning devices mostly use spinnerets similar to the size of syringe needles, so the Taylor cone formed on the top of the spinneret is generally Small droplets about 1 mm in diameter
In the electrospinning process, only a single jet is sprayed from the top of the small droplet, and the yield of nanofibers is low.

Abstract

The invention discloses a nanofiber yarn production device, and particularly relates to the field of nanofiber production.The nanofiber yarn production device comprises a box body, a partition plate is fixedly embedded in the middle of the interior of the box body, a production cavity and a spinning cavity which are symmetrically distributed about the partition plate are formed in the box body, and a feeding hopper is installed on one side of the top of the production cavity in a penetrating mode; a rotary drum roller blind is rotationally installed in the spinning cavity, and electrostatic plates are fixedly embedded in the two sides of the spinning cavity. Through the vertical reciprocating motion of the vertical rod, the function that the pressurizing spinning mechanism completes nanofiber production is achieved, the function that the recycling mechanism recycles a solution in the spinning cavity is also achieved, resource waste is reduced, the double-spraying nozzle reciprocates up and down along with the vertical rod, intermittent air spraying or liquid spraying of the double-spraying nozzle is achieved, and the production efficiency is improved. Not only can sprayed nanofibers be protected, but also liquid drops condensed on the needle tube spray head can be cleared through compressed airflow, so that the cleaning function is achieved, and the practicability of the device is greatly improved.

Description

technical field [0001] The invention relates to the technical field of nanofiber production, more specifically, the invention relates to a production device for nanofiber yarns. Background technique [0002] Electrospinning technology is a technology that uses electrostatic force to generate jets from polymer solutions or melts and finally solidifies them into nanofibers. The main principle of this technology is to first make the polymer solution or melt form surface curved droplets, liquid column films, bubbles, crater-like bulges, etc., and then use the electrostatic force to eject jets from the top of the curved surface. The jet flies to the negative plate under the action of electric field force, surface tension, etc., during which it is stretched and thinned, the solvent evaporates, the jet solidifies into nanofibers and finally deposits on the receiving plate to form a nanofiber mat. The diameter of nanofibers obtained by electrospinning technology ranges from tens of...
