Description

Technical Field

[0001] The utility model relates to the technical field of selenium drum protection, in particular to a selenium drum protection device. Background Art

[0002] The toner cartridge is a crucial component in laser printers and copiers, used to transfer printed images and text onto paper. The toner cartridge contains photosensitive material. During the printing process, a laser beam forms an electrostatic image on the drum surface. This image is then adsorbed onto the drum by toner (toner), and then transferred to the paper through heat and pressure, completing the print. The quality and lifespan of the toner cartridge directly impact both print quality and cost.

[0003] For example, the Chinese patent with publication number CN213832836U proposes a toner cartridge protection device, which includes a toner cartridge body and a protective shell. The toner cartridge body includes an outer shell, a photosensitive roller, a rotating shaft and two clamping columns. The outer shell is provided with a card slot, and the protective shell is provided with a side plate, a card hook, two card plates and a receiving cavity. A positioning groove is opened in the middle of the side plate. The photosensitive roller is fixedly sleeved on the rotating shaft, and the rotating shaft is movably installed in the outer shell. The rotating shaft can rotate in the outer shell, and both ends of the rotating shaft protrude from the outer shell. The two clamping columns are fixed Installed on the shell, when the protective shell is fixedly engaged on the toner cartridge body, the two ends of the rotating shaft are engaged into the positioning grooves, the hooks are engaged into the card slots, the photosensitive roller is accommodated in the accommodating cavity, and the two card plates are engaged between the two card columns. The protective shell can protect the photosensitive roller well and ensure that the photosensitive roller will not be bumped during the transportation of the toner cartridge. However, in this solution, the photosensitive roller is protected along with the main body. During transportation, the protection ability is general and the photosensitive roller is easily damaged. For this reason, we propose a toner cartridge protection device. Utility Model Content
