The material of the upper and lower corrugated rolls of the carton machinery

    The upper corrugating roller and the lower corrugating roller are the key components of corrugation forming. Usually the position of the lower corrugated roller is fixed, and the upper corrugated roller pressurizes the lower corrugated stick by means of spring, air pressure or oil pressure. The lower corrugated roller is the active roller, and the upper corrugated roller is driven by the meshing of the corrugated teeth of the roller and the lower corrugated roller.

    The material of the corrugated roller and the processing corrugated roller wear faster. After a certain period of use, the shape of the corrugated cardboard will change, making the thickness of the processed corrugated cardboard thinner, thereby reducing the compressive strength of the cardboard and affecting the quality of the corrugated cardboard. Therefore, there are strict requirements on the material, surface quality and heat treatment of the corrugated roll. The selection of corrugated roller directly affects the strength, rigidity and service life of the roller body.
