Description
Technical Field
The invention belongs to the technical field of printing consumable equipment, and particularly relates to a toner cartridge with a waste scraping blade.
Background
A toner cartridge, also known as a photosensitive drum, is generally composed of a base substrate made of aluminum, and a photosensitive material coated on the base substrate. In laser printers, more than 70% of the image forming components are concentrated in the cartridge, and the quality of printing is actually determined to a large extent by the cartridge. The cartridge determines not only the quality of the print, but also the amount of money the user spends during use.
The basic structure of a cartridge is generally composed of a base substrate made of aluminum, and a photosensitive material coated on the base substrate. Laser printers are currently in widespread use, with the toner cartridge being the primary component of the laser printer. The main core components of the cartridge include: the powder bin, the waste powder bin, the photosensitive drum, the charging roller, the developing roller, the powder feeding roller, the stirring frame, the cleaning scraper, the carbon powder sensor, the transmission mechanism and the like, wherein the transmission mechanism comprises a photosensitive drum gear, a developing roller gear, a powder feeding roller gear, a stirring frame gear and a plurality of transmission gears.
The carbon powder in the cartridge is the key to image during the printing process, and what is what the carbon powder will eventually form a document on the page. First we need to know what is called a latent image. The drum is a cylinder coated with an organic material (selenium, a rare element) on its surface, which is charged in advance, and when light is irradiated, a resistive reaction occurs at the irradiated portion. The transmitted data signals control the emission of laser, and the light scanning on the surface of the selenium drum is constantly changed, so that some places are irradiated, the resistance is reduced, the charges disappear, and other places are not irradiated by the light and still retain the charges, and finally, the surface of the selenium drum forms a latent image consisting of the charges.
In addition, the Chinese patent publication No. CN209373349U discloses a toner cartridge structure, which comprises a powder bin body, wherein a stirring frame is arranged in the inner cavity of the powder bin body, and a sensor is arranged on the inner wall of the powder bin body; the stirring frame comprises a rotary screw and a flexible sheet arranged on the rotary screw, and a magnetic sheet is arranged at one end of the rotary screw close to the sensor. However, the existing toner cartridge also has the problems that the generated waste toner is not easy to scrape out to influence the printing quality and the waste toner is inconvenient to clean.
In view of this, it is highly desirable to develop a cartridge with a waste scraping blade.
