MULTIFUNCTIONAL SPRAY APPARATUS WHICH AUTOMATICALLY MOVES ACCORDING TO SKEWNESS OF STRIP AND SPRAYS CLEANING SOLUTION CORRESPONDINGLY TO WIDTH OF STRIP TO ENHANCE DETERGENCY ON SURFACE OF STRIP

摘要

PURPOSE: To provide a multifunctional spray apparatus with enhanced detergency on the surface of strip, wherein the apparatus enables spray position to be moved according to skewness degree of strip, performs spraying operation correspondingly to width of strip and enables spray nozzles to be moved up and down so that the surface of strip is cleaned more uniformly. CONSTITUTION: The multifunctional spray apparatus comprises a slider(204) connected to a frame(217) in such a way that the slider is slid side to side by a pinion(202) driven by a motor(201) and a rack(203) engaged with the pinion; a cover(205) which is installed in front of the slider, and in which a space is formed so that a cleaning solution is supplied into the space; and a nozzle part connected to the front side of the cover, wherein a screw(209) rotationally operated by a motor(206) is installed in the inner space of the cover, cleaning solution spray range adjusting operation plates(208a,208b) are connected onto the screw, and the nozzle part comprises a screw rotationally operated by a motor(301), gears engaged with screw parts on the screw, cams(309) installed coaxially with the gears, wheels slid with the cams, and a plural spray nozzles(314) moved up and down by action of springs.
