Adhesive applicator for manufacturing core, core manufacturing apparatus, and adhesive application method using same

Abstract

The present invention discloses an adhesive applicator for manufacturing a core, a core manufacturing apparatus, and an adhesive application method using the same. The adhesive applicator includes: a nozzle body having at least one adhesive outlet; and a nozzle plug movably provided inside the nozzle body in order to open/close the adhesive outlet. The adhesive outlet includes a nozzle hole for discharging the adhesive from the inside to the outside of the nozzle body, and the nozzle plug includes a plug body movably provided inside the nozzle body to selectively block the nozzle hole, and a plug tip formed to protrude on a fore-end surface of the plug body. The fore-end surface of the plug body has a flat surface which faces the nozzle hole and is orthogonal to an axis of the nozzle hole. According to the present invention, since processing precision and processing easiness of the nozzle plug for opening/closing the adhesive outlet and the adhesive outlet can be enhanced, an adhesive application amount applied to the material by the adhesive applicator having a plurality of adhesive outlets can be uniformly managed.
