Normal > "Hot-press reclaimed corrugating roller" is a method of regenerating corrugated rollers that are discarded after use. This technology enables corrugating rollers to reach and exceed the specifications of the original corrugating roller. Normal > Hot-press sleeve technology Renewed corrugating roller Normal> The principle is to turn all the enamel teeth of the corrugating roll away, and then hold the mandrel to hold the mandrel and then re-build the teeth so that it can reach the original factory's performance indicators. Now it has been successfully established in China. By combining the surface hardening treatment technology, the surface hardness of the reproducible corrugated roller rake tooth can reach more than HRC58 and the depth of the hard layer reaches 1.2mm . The method for regenerating and repairing corrugating rollers is suitable for various corrugated rollers produced by different packaging machinery factories used in various carton factories, and has a wide application prospect. The technology can avoid the occurrence of crushing and tooth breakage during use and prolong the service life of the corrugating roller. The material cost saved by refurbishing the corrugating roller through this method is equivalent to 20% of the selling price of the new roller . Normal > Discussion on the methods of repairing corrugated rolls in the past Normal > Each manufacturer often uses a reduced corrugating roller's outer length to ensure a high repair method to repair worn corrugating rollers. As shown in Fig. 1, since the pitch becomes smaller, t > t1 >t2 , the paper shrinkage rate of the core paper is increased, and the paper is wasted. Table 1 shows an example of a C roller.
