Description
Technical Field
The utility model relates to a printing consumables field indicates a scraper device that uses with laser printer selenium drum cooperation especially.
Background
A contact developing selenium drum for laser printer is composed of laser beam emitted by laser, acousto-optic deflecting modulator, binary image-text lattice information from computer, character generator, 9 HF oscillators controlled by signals generated by synchronizer, frequency synthesizer and power amplifier, and acousto-optic modulator. The modulated light beam is emitted into the multi-surface rotating mirror, and then is focused by the wide-angle focusing mirror and then is emitted onto the surface of the selenium drum through the light guide, so that the angular velocity scanning is changed into linear velocity scanning, and the whole scanning process is completed. The surface of the selenium drum is firstly charged by a charging electrode to obtain a certain potential, then the surface of the selenium drum is exposed by a laser beam carrying image-text image information, so that an electrostatic latent image is formed on the surface of the selenium drum, the electrostatic latent image is developed by a magnetic brush developer, the latent image is converted into a visible toner image, the toner is transferred onto plain paper under the action of an electric field of a transfer electrode when passing through a transfer area, and finally the toner is fixed by a preheating plate and a high-temperature hot roller, so that characters and images are fused on the paper. Before printing the image-text information, the cleaning roller removes the ink powder which is not transferred, the electricity-eliminating lamp removes the residual charge on the drum, and the drum is thoroughly cleaned by the cleaning paper system, so that a new working cycle can be started.
The scraper and the mounting plate of the existing laser printer are generally arranged on the same plane, and the connection strength between the scraper and the mounting plate is not enough. Because the scraper is long, thin and wide, the phenomenon of 'jumping' of the scraper is easy to occur when the surface of the toner cartridge is cleaned, and the matching precision of the surface of the toner cartridge and the scraper is not enough due to the phenomenon of 'jumping', so that the local powder spraying phenomenon of the toner cartridge is caused, and the whole printing quality is influenced. Therefore, the flexibility requirement of the scraper and the rigidity requirement of the installation between the installation plate and the scraper are problems to be solved at the same time.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the purpose of the application is to provide a novel toner cartridge scraper device, which can not only avoid the phenomenon of 'jumping over' when powder is discharged from the surface of a toner cartridge, thereby avoiding the phenomenon of powder spraying on the local part of the toner cartridge and ensuring the printing quality.
According to an aspect of the present application, in order to achieve the above technical effects, the present application provides the following technical solutions:
design a novel selenium drum scraper device, include: the scraper and the mounting plate are rectangular, the thickness of the mounting plate is more than or equal to 1.2mm, and mounting holes are respectively formed in two ends of the mounting plate; the scraper is in an L-shaped right-angle structure, and the thickness of the scraper is smaller than that of the mounting plate; one side of the scraper is fixedly attached to one side of the mounting plate and is vertical to each other, and the mounting hole and the scraper blade are not on the same horizontal plane.
Owing to adopt and design the scraper for right angle "L" shape, be set for being more than or equal to 1.2mm with the mounting plate thickness, closely laminate fixedly and both each other for technical scheme such as perpendicular with the vertical one side of scraper, make the selenium drum scraper device of this application compare with prior art and have: the connection degree that the laminating was very inseparable and had strengthened the cutter between scraper and the mounting panel is strong, and the stability that the scraper group will has also obtained the reinforcing, "jump sword" phenomenon can not appear when going out the powder to the selenium drum surface to stopped the local phenomenon of dusting of appearing of selenium drum, also made the selenium drum surface better with scraper cooperation precision, guaranteed the quality of whole printing.
In order to obtain better technical effect, the application also has the following technical characteristics:
in some embodiments, to meet the flexibility requirements of the scraper and the rigidity requirements of the mounting between the mounting plate and the scraper, the scraper is provided as a metal sheet and slightly shorter than the mounting plate, the mounting plate is provided as a metal plate, and the scraper is bonded or spliced or riveted or welded on one side of the mounting plate.
In some embodiments, in order to facilitate the adjustment of the contact position of the scraper and the surface of the toner cartridge, the toner can be discharged from the surface of the toner cartridge more completely, and the mounting hole is designed to be oval.
In some embodiments, to facilitate replacement and maintenance of the doctor blade assembly, a mounting plate is removably disposed on the powder hopper with the outer side of the doctor blade in mating contact with the developer roller surface.
In some embodiments, the material of the scraper can be selected from iron or aluminum or stainless steel sheets according to different requirements of toughness and rigidity of product models and functions, and the mounting plate is made of the iron or aluminum or stainless steel sheets in order to enhance the stability of the scraper group.
In some embodiments, in order to facilitate the adjustment of the contact position of the scraper with the surface of the toner cartridge, it is preferable that the mounting holes at the two ends of the mounting plate are designed to be round holes at one end and elliptical holes at the other end.
