Description

Improvement type galley roller

Technical Field

The utility model relates to the technical field of printing rollers, in particular to an improved printing roller.

Background

At present, most of heating methods of plate roller printing machines needing to heat plate rollers are electric heating methods, and mainly heat a roller body through heat radiation generated by an electric heating rod arranged inside the roller body. However, because the plate roller needs to rotate continuously during working, heat transfer is slow, the mechanism is easy to loosen and fall off, heat reduction shortens the service life of the heating chamber, the common method is to reinforce the heating rod, and the stability of the heating chamber is improved by using a relatively complex fixing structure, but practice proves that the stability of the heating chamber cannot be effectively improved by the complex structures, and the complex structures still need to be improved.
