Description
Technical Field
The invention relates to the technical field of regeneration processes, in particular to a regeneration process of a magnetic roller.
Background
The toner cartridge is the most central consumable part of the laser printer, more than 70% of imaging components are concentrated in the toner cartridge in the laser printer, and the quality of printing is determined by the toner cartridge in fact to a great extent. The magnetic roller is one of important parts in the toner cartridge, and the roughness of the surface of the magnetic roller can influence the printing quality and is one of the parts which have the greatest influence on the blackness of the printing quality. After a period of use, the graphite coating on the surface of the magnetic roller is basically worn completely, so that the magnetic roller loses the original surface roughness, a large friction force is generated between the magnetic roller without the surface roughness and a powder discharging knife, and then the carbon powder on the surface of the magnetic roller cannot well obtain enough charge, the carbon powder with insufficient charge presents serious light-color and color-cast printing defects in the printing process, and at the moment, a new magnetic roller needs to be replaced. If the replaced waste magnetic roller is directly discarded, the environment is polluted, and great resource waste is caused, so that the waste magnetic roller needs to be recycled and reused at present. If the surface roughness of the magnetic roller can be processed to reach the established parameter standard and the printing quality of the magnetic roller is even better than the brand new printing quality of the magnetic roller under the condition of matching with other parts, the benefit is very considerable.
