Abstract
The utility model discloses a toner cartridge of a laser printer, which comprises a carbon powder bin, carbon powder loaded in the carbon powder bin, and a magnetic roller and a powder control device which are arranged on the carbon powder bin. A photosensitive drum is arranged above the magnetic roller, and a cleaning scraper and a charging roller are arranged on the photosensitive drum. The cleaning scraper comprises a cutter frame, an upper blade and a lower blade, wherein both the upper blade and the lower blade are mounted on the upper and the lower sides of the cutter frame respectively and are not in contact with each other. A brush strip is pasted on the upper blade and in a position opposing to the photosensitive drum, during the operation, not only the surface of the photosensitive drum is prevented from being damaged, but also residual carbon powder can be removed well, the stability of printing quality is improved greatly, and the service lives of the photosensitive drum and a printer are prolonged.
Description
Technical field
The utility model printer field relates to a kind of new pattern laser printer toner cartridge.
Background technology
The surface coating of the photosensitive drums of printer is very easily damaged, is scratched.The image processing system of printer is in print procedure, and the magnetic image still has carbon dust to remain in photosensitive drum surface after being transferred on the recording chart from photosensitive drums, thereby need utilize cleaning doctor to remove residual carbon dust.General cleaning doctor comprises cutter and a slice blade; Blade and photosensitive drums only have a contact point; With residual carbon dust clean the time, cleaning doctor often applies bigger pressure at the contact point place to photosensitive drum surface, often produces the photosensitive drum surface wearing and tearing of contact point place; Shorten the serviceable life of photosensitive drums and printer, reduce the stability of print quality.Thereby study to have and neither damage photosensitive drum surface, can well know the printer toner cartridge of the cleaning doctor of residual carbon dust again, be an important research project.
The utility model content
The utility model technical matters to be solved is the deficiency that overcomes prior art; A kind of new pattern laser printer toner cartridge is provided; Has good cleaning doctor; Neither damage photosensitive drum surface, can well know residual carbon dust again, improve the stability of print quality and the serviceable life of photosensitive drums and printer.
The technical solution of utility model is following:
A kind of new pattern laser printer toner cartridge comprises toner, is loaded on the carbon dust in the toner and is arranged at the magnetic roller and control powder device on the toner;
Said magnetic roller top is provided with photosensitive drums, and photosensitive drums is provided with cleaning doctor, photosensitive drums and charging roller;
Said cleaning doctor comprises knife rest, cutter and bottom knife, and cutter and bottom knife are installed in the upper and lower both sides of knife rest respectively;
The bottom of said cutter is pasted with the hairbrush bar.
Beneficial effect:
The utility model laser printer toner cartridge; Its cleaning doctor comprises a knife rest and upper and lower two blades, and upper and lower two blades are installed in the upper and lower both sides of knife rest respectively, do not contact mutually; Cutter and photosensitive drums opposite position are pasted with the hairbrush bar; Can guarantee neither to damage photosensitive drum surface, can well know residual carbon dust again, improve the stability of print quality and the serviceable life of photosensitive drums and printer.
Description of drawings
Fig. 1 is the laser printer toner cartridge synoptic diagram of the utility model.
1 is toner among the figure, and 2 is carbon dust, and 3 are control powder device, and 4 is the magnetic roller, and 5 is photosensitive drums, and 6 is cleaning doctor, 61 knife rests, and 62 is bottom knife, and 63 is cutter, and 64 is the hairbrush bar, and 7 is charging roller.
Embodiment
Below will combine accompanying drawing and specific embodiment that the utility model is explained further details:
As shown in Figure 1, a kind of new pattern laser printer toner cartridge comprises toner, is loaded on the carbon dust in the toner and is arranged at the magnetic roller and control powder device on the toner; Said magnetic roller top is provided with photosensitive drums, and photosensitive drums is provided with cleaning doctor, photosensitive drums and charging roller; Said cleaning doctor comprises knife rest, cutter and bottom knife, and cutter and bottom knife are installed in the upper and lower both sides of knife rest respectively; The bottom of said cutter is pasted with the hairbrush bar.
During operation, the hairbrush bar of cutter contacts with photosensitive drum surface respectively with bottom knife, and in cleaning course, along with the rotation of photosensitive drums, the carbon dust of photosensitive drum surface at first passes through the wiper of hairbrush bar, reaches homogeneous thickness.Then bottom knife is adjusted to suitable length; Can not need under the very big pressure carbon dust to strike off with photosensitive drum surface; Neither damage photosensitive drum surface, can well know residual carbon dust again, improved the stability of print quality and the serviceable life of photosensitive drums and printer greatly.
