TECHNICAL FIELD

[0001] The utility model relates to printer accessory technical field especially relates to a printing selenium drum magnetic roller. BACKGROUND

[0002] The background of printing selenium drum magnetic roller relates to one of the key components of the printer, which plays a crucial role in the printing process. The selenium drum magnetic roller, also known as a developing roller or magnetic roller, is usually set inside the selenium drum of the printer, especially at the outlet of the carbon powder bin. This design allows the magnetic roller to effectively contact the carbon powder and perform its function. The magnetic roller is typically composed of a core shaft, an aluminum tube (or steel shaft), a transmission head, and a conductive bracket head. In traditional processes, the aluminum tube surface is sprayed with a layer of coating to enhance its performance. The main function of the core shaft is to adsorb the carbon powder inside the selenium drum, which can be achieved as long as the core shaft has a certain area of magnetic material. However, the traditional core shaft design often has the entire core shaft with magnetism, which not only leads to unnecessary material consumption but also increases the manufacturing cost. In the publication number CN212060878U, an intelligent printing selenium drum magnetic roller is disclosed. When in use, the carbon powder is pushed into the inside of the discharge pipe by the discharge wheel, and the carbon powder is sent to the upper surface of the conductive rubber surface layer through the discharge end of the discharge pipe. The carbon powder is uniformly guided by the buckle plate, but the guiding effect of the buckle plate on the carbon powder is limited, which adversely affects the quality of the final product.
