Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a metal cutter and a toner cartridge. Background Art

[0002] The toner cartridge is a part of the copier, and its function is similar to that of the printer's ink cartridge. It is a thin cylinder with toner powder on the surface. There are two types of toner cartridges: integral (or integrated) and separate. In the separate toner cartridge, the toner powder and the photosensitive drum are placed on different devices. The photosensitive drum generally has a long lifespan, and can generally print up to 20,000 pages. You only need to replace the consumed toner powder, which greatly reduces the user's printing cost.

[0003] The cleaning blade in the toner cartridge, also called the cleaning knife, is a large blade that is in linear contact with the photosensitive drum to clean the toner that has not been completely transferred on the surface of the photosensitive drum and to block the toner that has not been completely transferred, so that the toner falls into the waste toner box; the powder discharge knife in the toner cartridge has the same structure as the cleaning blade, and is mainly used to rub with the magnetic roller (MR) to charge the toner particles and control the thickness of the toner layer on the surface of the magnetic roller cover, so that the toner is evenly transferred out; the powder discharge knife and cleaning blade on the market are generally divided into two types, one is composed of a metal base and a polyurethane sheet, and the other is composed of pure metal;

[0004] However, during the use of pure metal cleaning scrapers and powder discharge knives, due to their own physical properties, the knives themselves are cool. During use, the toner containing a certain amount of water will directly adhere to the knives. When the toner accumulates on the powder discharge knife, the font color of the printed data will be lighter; and when there is too much toner attached to the cleaning scraper, it is easy for the cleaning knife to fail to scrape the waste toner on the outer surface of the toner cartridge, and the presence of waste toner will affect the printed data;

[0005] Therefore, it is necessary to design a kind of metal cutter and toner cartridge that can reduce the carbon powder dependence cutter. Utility Model Content

[0006] In order to solve the above problems, the utility model provides a metal cutter and a toner cartridge to more accurately solve the above problems.

[0007] The utility model is realized by the following technical solutions:

[0008] The utility model proposes a metal tool, comprising a cleaning scraper and a powdering knife, wherein the cleaning scraper and the powdering knife each comprise two mounting ends and a plate body arranged between the two mounting ends, an extension plate being connected to the bottom or top of the plate body, the extension plate and the plate body being arranged in an L shape, the end of the extension plate being inclined downward or upward and forming a protrusion for outputting or scraping powder, and at least one heating element being arranged on the plate body.

[0009] Furthermore, in the utility model, the heating element comprises a ceramic heating plate.

[0010] Furthermore, the utility model provides circular holes on the plate body through which the positive and negative lead wires of the ceramic heating plate pass.

[0011] Furthermore, the utility model provides mounting holes on both mounting ends.

[0012] A toner cartridge comprises a shell, wherein any one of the metal cutters described above is arranged inside the shell.

[0013] The utility model further comprises a plurality of battery compartments arranged on the shell, wherein the battery compartments contain storage batteries connected to the heater and supplying power to the heater, and a battery cover is connected to the top of the battery compartments.

[0014] Beneficial effects of the utility model:

[0015] The setting of the heating element can heat the cleaning scraper and the powdering knife themselves. Due to the thermal conductivity of the cleaning scraper and the powdering knife themselves, the heat generated by the heating element will be quickly conducted to the cleaning scraper and the powdering knife, thereby increasing the temperature of the cleaning scraper and the powdering knife themselves. During the use of the heated cleaning scraper and the powdering knife, due to the change in their characteristics, they will heat up the environment in which the tool is located, and heat the carbon powder moved to the tool. The increase in ambient temperature and the temperature of the tool itself can effectively reduce the water content in the carbon powder, and the carbon powder with reduced water content is not easy to adhere to the tool; even if a certain amount of carbon powder adheres to the tool, due to the heat of the tool itself, the water molecules in the attached carbon powder will continue to evaporate, and the carbon powder attached to the tool will gradually reduce its viscosity due to the heat of the tool, and gradually fall off the tool.
