Description

Dismounting device for paper guide roller bearing Technical Field The utility model relates to the technical field of smoke ventilator equipment, in particular to a dismounting device for a paper guide roller bearing. Background When producing and manufacturing cigarettes, the cigarette paper, tipping paper and forming paper on the filter stick are all required to be supplied in large quantity, so the paper tape supply is a core process of the cigarette machine equipment, and the paper guiding roller is widely applied to the cigarette machine equipment based on the characteristics of being capable of changing the paper tape path, stabilizing the paper tape tension and the like. In the operation process of the smoke machine equipment, the paper guide roller is always in contact with the running paper tape and generates relative friction force, so that residues such as paper powder and paper scraps are accumulated at the paper guide roller, when part of residues enter the paper guide roller, the paper guide roller is easy to damage, the paper guide roller is inflexible to rotate, the paper tape is further broken, equipment is stopped due to the failure, and the equipment efficiency is influenced, so that the bearing needs to be replaced in time.
