Inspection of corrugator roll before installation
(1) clean and check the corrugated surface appearance of corrugator roller (including the quality of surface plating).
(2) clean and check all fastening parts of connection (including internal and external threads).
(3) check the outer diameter and middle height of corrugator roll (the whole roll surface is divided into more than five measuring points from both ends to the middle).The middle and high detection points are odd, and the middle and high data should be symmetrical on both sides.Measure with the outside diameter micrometer of corresponding specification (outside diameter micrometer can be bought commonly by electromechanical company).
(4) check the corrugator roll height.Needle type depth dial meter measurement (needle type depth dial meter is not currently bought in China, must be imported.Or may use the ordinary depth dial gauge to change the system).
(5) clean and check the outer diameter and appearance of each shaft gear of corrugator roll, and measure the outer diameter with the micrometer of corresponding specifications.
