Description

Technical Field

[0001] The utility model relates to the field of printer accessories, in particular to a toner cartridge with a double-layer cleaning scraper. Background Art

[0002] The toner drum is a thin, cylindrical component of a copier, coated with toner. It functions similarly to a printer cartridge. The most critical component of a good laser printer is the drum, also known as the photosensitive drum. It not only determines print quality but also the cost of the printer. In a laser printer, over 70 percent of the imaging components are concentrated in the drum, and print quality is largely determined by the drum itself.

[0003] There is a scraper in the toner cartridge that scrapes the drum core. The scraper is mainly responsible for removing the toner remaining after the image is transferred from the photosensitive drum. During the printing or copying process of the printer or copier, the toner forms an image on the toner drum and then transfers it to the copy paper. During this process, some toner will remain on the toner drum. If this part is not removed, it will be transferred to the next copy paper when the next copy is made, which will affect the copy effect and quality of the next copy. At this time, a device is needed to remove the toner remaining on the toner drum after the copier has copied a page. This device is a toner drum scraper. The quality of a scraper is very important. It directly determines the copy quality and the service life of the toner drum. Traditional toner drum scrapers are generally rigid single-layer scrapers with large force. Repeated scraping will cause damage to the toner drum, and the single-layer scraper is also less convenient to install. Based on this, the utility model proposes a toner cartridge with a double-layer cleaning scraper. The toner cartridge utilizes a combined scraper assembly, which can provide floating support for the entire scraper, avoiding damage to the toner cartridge caused by rigid scraping. The scraper is installed through a locking pin and a connecting pin, and has better disassembly and assembly. The scraper adopts a combination of a front scraper and a rear scraper, and has better strength and service life. Utility Model Content
