Inner peripheral heating corrugated roller

Abstract

The invention relates to an inner peripheral heating corrugated roller. The inner peripheral heating corrugated roller comprises a corrugated roller body, a plurality of groups of steam channels are arranged in the corrugated roller body, each group of steam channels is annularly and uniformly distributed around the center of the corrugated roller body and close to the outer wall surface of the corrugated roller body; each group of steam channel comprises more than four pipelines, the pipes point along the axis direction of the corrugated roller body, and the pipelines are sequentially in communication; and one end of the corrugated roller body is provided with a steam inlet channel and a steam return channel, and the two ends of each steam channel are in communication with the steam inletchannel and the steam return channel correspondingly. According to the inner peripheral heating corrugated roller, the steam channels are distributed on the wall of the corrugated roller body, due tothe fact that the steam channels are close to the outer wall surface of the corrugated roller body, the heating speed is high, and the heat loss is reduced.

Description

technical field [0001] The invention relates to a corrugated roller, in particular to a corrugated roller with inner peripheral heating. Background technique [0002] At present, the heating method of corrugated rollers used in corrugated cardboard equipment is: a thermal cylinder is installed inside the roller body. Due to the large internal space of the thermal cylinder, it takes a long time to be filled with saturated high-temperature steam, and, because the wall is thicker, the heat of the steam It also takes a long time to transfer to the surface of the roller body, increasing the loss of heat. In addition, due to the large temperature difference between the upper and lower sides of the roller body, the roller body is deformed. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the above-mentioned prior art, and provide a corrugating roll with inner peripheral heating that reduces heat loss, reduces deformation ...
