Description

Technical Field

[0002] The corrugating roller is an important key part of the single-sided machine. The corrugating roller is divided into an upper corrugating roller and a lower corrugating roller. The upper and lower roller surfaces are both female, and the two rollers are paired and meshed.

[0003] For example, the Chinese authorized patent with announcement number CN219789478U (a new type of corrugated roller structure): including a roller body, end shafts are provided at both ends of the roller body, an inner cavity is provided inside the roller body, and an outer ring cavity is provided inside the roller body on the outer peripheral side of the inner cavity, a siphon is provided at one end of the roller body, and a valve tube is sleeved on the peripheral side of the siphon. The corrugated roller structure provided by the utility model is divided into an inner and outer ring cavity structure, steam first enters the outer ring cavity to preheat the roller body, and then enters the inner central cavity. Compared with the traditional roller body structure, the corrugated roller structure is heated evenly and the heating time is short. The corrugated roller is not easy to deform, which can ensure the normal, continuous and efficient production of corrugated paper.

[0004] However, most of the existing corrugated rollers are heated by high-temperature steam entering the roller body. It takes a long time for the high-temperature steam to heat the distant parts, and the nearby and distant parts will be heated unevenly; therefore, it does not meet the existing needs. In this regard, we have proposed a peripherally heated and highly wear-resistant corrugated roller. Utility Model Content
