Magnetic roller is an important mechanical component, widely used in various industrial fields, especially in printing and metal sorting.
Structure and function of magnetic roller
The magnetic roller is mainly composed of magnetic core, bracket, conductive wire and magnetic sleeve. The magnetic sleeve is composed of aluminum layer and coating, and the coating needs to have certain conductivity, wear resistance and roughness. The main functions of the magnetic roller include:
Adsorbing toner: The toner in the powder bin is attracted to the surface of the magnetic roller sleeve through the internal magnetic core.
Charging toner: The coating on the surface of the magnetic sleeve rubs against the toner particles and the polyurethane sheet on the powder discharge knife, so that the toner is charged with static electricity.
Adsorbing toner to the drum core: The charged toner is "jumped" between the magnetic roller sleeve and the drum core OPC surface through AC (alternating current) and DC (direct current) voltage, so that the "static latent image" on the drum core surface is adsorbed to the toner
