Description

Technical Field

[0001] This utility model relates to the field of charging rollers, and more specifically, to a charging roller cleaning device. Background Technology

[0002] Charging rollers are a new type of environmentally friendly charging method. This method reduces ozone generation, provides uniform charging, and is noiseless. It is widely used in laser printers and also has applications in low-speed copiers.

[0003] A search revealed an existing patent (publication number: CN221326936U) disclosing a charging roller cleaning device, relating to the field of printing equipment technology. The device includes: a housing, a charging roller, a photosensitive drum, a cleaning component, and a rotating component. The charging roller is located inside the housing, the photosensitive drum is located on one side of the charging roller, the cleaning component is located inside the housing near the charging roller for cleaning toner adhering to the charging roller, and the rotating component is located on the outer end of the housing. This charging roller cleaning device effectively removes toner adhering to the charging roller through the cleaning component, solving the problem that the contact surface between the charging roller and the cleaning cotton remains fixed. This increases the cleaning area of ​​the charging roller, facilitating the removal of toner and ensuring normal operation. The rotating component drives the charging roller to rotate, increasing the cleaning force and speeding up the cleaning process, thus improving cleaning efficiency. The inventors discovered the following problems with the existing technology during the development of this invention:

[0004] Existing charging rollers are typically cleaned after production and then packaged. The cleaning of existing charging rollers is usually done directly by machine. However, due to the different sizes of the charging rollers, the brushes may not make complete contact during cleaning, resulting in incomplete cleaning. Therefore, a cleaning mechanism is needed to clean charging rollers of different sizes. At the same time, the aforementioned cited patent documents do not propose any solutions to address the problem of cleaning charging rollers of different sizes.

[0005] Therefore, a charging roller cleaning device is proposed to address the above problems. Utility Model Content
