Corrugating Roll, as the most important part of corrugated cardboard production line, whose abrasion resistance and service life is the main technical index for measuring quality and economical efficiency, directly influences the economic benefits of manufacturer for corrugated cardboard .It is generally used 48CrMoA steel, after the surface heat treatment and cold treatment or surface treatment, the hardness is generally above HRC55.
Huatao provide Tungsten Carbide Corrugating Roll and Chrome corrugating roll.
The corrugated roller is the key parts of the single machine. The corrugated roller is divided into corrugated roller and lower corrugating roller, upper and lower roller surface are female shape, and two pair meshing assembly, the meshing gear transmission mechanism is different from the usual. Corrugated roll as a driving roller, shaft with gear motor via speed reducer drive corrugated roll rotation. Upper corrugating roller is driven roller, roller and roller on under the roller tooth meshing transmission. In order to make the corrugated paper, corrugated roll between corrugating molding, must exert some pressure on the corrugated roller. So the corrugated roller in addition to rotate around its axis. The mobile line and along the upper and lower corrugating roller axis. This move is applied through the cylinder radial pressure to the corrugated roller ends, the corrugated roller mesh generation nip pressure.
