Abstract
Disclosed is a nozzle block applied to an electrospinning device. At least one piercing unit (means of piercing) having a diameter smaller than the inner diameter of a spinning nozzle is coaxially disposed inside the spinning nozzle in order to prevent solidification of a solution at a tip of the spinning nozzle. The present disclosure includes a first cleaning mechanism for cleaning the spinning nozzle by reciprocating the piercing unit and the spinning nozzle relative to each other so that the tip of the spinning nozzle is unclogged, and a second cleaning mechanism for cleaning aggregates deposited around and outside the tip of the spinning nozzle through chemical cleaning and/or physical cleaning when the electrospinning process is temporarily stopped or after the electrospinning process is completed.
