Description

Technical Field

[0001] The utility model relates to the technical field of selenium drums, in particular to a selenium drum structure with an adjustable selenium drum magnetic core roller. Background Art

[0002] Toner cartridges, also known as photosensitive drums, are key components in laser printers, copiers, fax machines and other equipment. The magnetic roller in the toner cartridge is composed of an aluminum tube and a magnetic core roller. During the printing process, the magnetic toner in the powder bin is adsorbed to the surface of the magnetic roller by the magnetic core roller, and then the powder knife evenly scrapes the toner on the surface of the magnetic roller to control the thickness of the toner layer on the surface of the magnetic roller. During the scraping process, the toner is charged by friction, and then the negatively charged toner particles are pushed to the electrostatic latent image area of ​​the OPC drum through the electric field force between the OPC drum and the magnetic roller.

[0003] In the traditional toner cartridge structure, if the magnetic pole position deviates after the core roller is installed, the toner cartridge needs to be disassembled, the core roller needs to be replaced or adjusted. This rework process is very cumbersome and consumes a lot of time and manpower, seriously affecting production efficiency. Frequent disassembly and replacement of the core roller will lead to an increase in the scrap volume of the core roller, increasing production costs. Utility Model Content
