Problems solved by technology

[0003] In the existing rubber roller treatment process, the rubber layer is completely removed by turning process. During this process, the metal roller core will also be turned off by 1-2 mm. After repeated renovations, the outer diameter of the roller core will continue to decrease, usually 5 times. After that, it will be scrapped, and the factory has to produce a new roller core, resulting in waste of resources and increased costs; in addition, the dynamic balance of the roller core will also be affected after each treatment, and it needs to pass a dynamic balance test before it can be reused

Abstract

The invention discloses a roller core treatment process. The roller core treatment process comprises the following steps of turning a rubber layer on the surface of a roller core to a preset thickness, and then throwing away the rubber layer with sandpaper. Turning the metal roller core of a rubber roller is not required, tool wear is reduced, the outer diameter of the roller core before and afterprocessing remains unchanged, the dynamic balance is not affected, the rubber roller can be renovated for many times, the production cost is greatly reduced, and the production resources are saved.

Description

technical field [0001] The invention relates to the technical field of rubber roller refurbishment, in particular to a roller core treatment process. Background technique [0002] Rubber roller refers to a roller-shaped product made of metal or other materials as the core and covered with rubber after vulcanization. It is widely used in various industrial fields, such as papermaking, printing and dyeing, and metallurgy. During the use of rubber rollers, the surface rubber will age, or be corroded by solvents, inks, etc., or scratched by sharp objects, so it is necessary to refurbish the old rubber rollers. [0003] In the existing rubber roller treatment process, the rubber layer is completely removed by turning process. During this process, the metal roller core will also be turned off by 1-2 mm. After repeated renovations, the outer diameter of the roller core will continue to decrease, usually 5 times. After that, it will be scrapped, and the factory has to produce new r...
