ROUNDEL TIP OF SWIRL GUN FOR SEALANT COATING

摘要

PURPOSE: Provided is a roundel tip of swirl gun for sealant coating in which nipple is inserted into the through hole of the supporting ball so that the nipple carries on the precession motion around the support ball and changes the width of the spiral bead of the sealant by changing the position of the above support ball. CONSTITUTION: The roundel tip comprises: a flexible pipe like tube (1) made of metal and resin complex; a hallow shaft motor (2) which tube is extended to the bottom part; a revolving eccentric housing (3) with eccentric through hole which is attached to the hallow shaft motor and makes eccentric axis of interior cylinder; a circular nipple support layer (4) situated in above eccentric through hole with the central through hole; a metal pipe type nipple (5) located and extended to the bottom in the through hole of nipple support layer, upper part of which is connected to the tube so that sealant moves inside; support ball (6) of circular type supporting nipple which is inserted into the through hall and angle control device (7) to support the revolving the support ball. As the hallow shaft motor revolves, the eccentric housing revolves, nipple support layer revolves eccentrically, the nipple moves in precession motion around the above support ball and the angle of above precession motion is controlled by the angle control device.
