Description
Technical field
The utility model relates to printer ink powder box technical field; Specifically, relate to a kind of printer ink powder box powder cartridge scraper, be particularly useful for color laser printer; Be used for evenly and keep the electrical consistance of ink powder the ink powder sheaing, and be can local replacing the split blade type structure.
Background technology
The groundwork principle of laser printer of the prior art is:
As shown in Figure 5, mainly by cloth electricity wheel 1, photosensitive drums 2, the ink powder that magnetic roller 3 prints content distributes, and magnetic roller 3 is developing apparatuss of the prior art, is made up of magnetic core and the sleeve that is sleeved on the magnetic core outside.During work; At first by cloth electricity wheel 1 distributed charge, make current potential initialization on the photosensitive drums 2, in order to the irradiation of laser beam; Thereafter; Utilize laser want images printed data to be radiated at the electrostatic latent image zone on the photosensitive drums 2 that is full of electric charge, the electrostatic latent image zone is produced the different potential data by record, causes the CHARGE DISTRIBUTION that is similar to exposure effect.And ink powder is owing to receive the sleeve surface of the effect absorption left magnetic roller 3 of magnetic field force; And along with controlling the rotation of powder device and forming certain thickness ink powder in sleeve surface, ink powder moves to the electrostatic latent image zone of photosensitive drums 2 then, and this electrostatic latent image is developed; Promptly fill uniform ink powder developer in the zone that image or literal are arranged; At last, will pass through image that developer fills or words transfer printing to medium, get final product through photographic fixing again.Therefore, the thickness and the uniformity coefficient on developer left magnetic rollers such as ink powder 3 surfaces with directly influencing the picture quality that forms on the photosensitive drums 2, finally influence printing effect.
Therefore, need to use control powder mechanism to come powder outlet quantity is carried out in good time adjusting, guarantee as much as possible that promptly the thickness of powder delivery is consistent with uniformity coefficient.
Control powder mechanism contacts the uniformity coefficient that guarantees powder delivery through powder cartridge scraper or powder delivery cutter with magnetic roller 3, but As time goes on, powder cartridge scraper or powder delivery cutter and magnetic roller all have certain wearing and tearing, and the uniformity coefficient of powder delivery and thickness also can be affected.
The utility model patent of ZL201020572935.4 discloses " a kind of control powder device that is used for the laser printer toner cartridge "; This utility model is through being provided with spongy elastic body on knife rest; And coat the mode of film on spongy elastomeric surface, powder delivery is regulated.This utility model patent comes the mismachining tolerance or the rigging error of knife rest, spongy elastic body itself are compensated through utilizing spongy elastomeric elastic deformation, compared to prior art, improves to a certain extent really.
But still there is certain defective in above-mentioned patent, and film and spongy elastic body itself that promptly spongy surface of elastomer coats still can wear and tear, thereby influence the homogeneity of later stage powder delivery and the consistance of thickness.
The utility model patent of ZL200420122272.0 discloses a kind of powder cartridge scraper of powder box; Comprise a support bar and a scraping plate part; This scraping plate part is to be formed by scraper plate body coating layer protective layer on integral surface; And this scraping plate part is fixed on this support bar, and is extruded with a cloth scraping end, so as to the sheaing carbon dust.But there is defective equally in this utility model patent, and promptly scraping plate part is a scraper plate that is strip on the whole, is close to the surface of left magnetic roller 3 and scrapes powder.Will be appreciated that the scraper plate of strip is fitted through long with magnetic roller 3, local wearing and tearing must occur, scraper plate itself also certain distortion can occur, causes with the applying on magnetic roller 3 surfaces not tight.
Therefore, in order to overcome the deficiency of prior art, adapt to the needs of reality, be necessary to design a kind of powder cartridge scraper of novel printer ink powder box, be intended to keep for a long time the homogeneity of powder delivery and the consistance of thickness.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, adapts to the needs of reality, and a kind of printer ink powder box powder cartridge scraper is provided.
In order to realize the purpose of the utility model, the technical scheme that the utility model adopts is:
A kind of printer ink powder box powder cartridge scraper; Comprise scraping plate part; One side of said scraping plate part top is provided with the back up pad that is used for support scratch board portion, and the top and the back up pad of said scraping plate part are fastenedly connected, and said scraping plate part is the split blade type structure; Staircase structural model through sidewall between each burst of said scraping plate part is nested type combination successively, and the forward and backward surface of each burst of said scraping plate part is all in same plane.
Said scraping plate part is an elastic plate.
The top of said scraping plate part is fastenedly connected through rivet and back up pad.
Said back up pad is that sheet metal and having is used for and electrically passes to the connecting hole that device is connected, and the outside surface of said scraping plate part is provided with the metallic conduction coating.
Said metallic conduction coating is a silver coating.
The beneficial effect of the utility model is:
1. novel structure; Scraping plate part be designed to the split blade type structure; And the staircase structural model through sidewall between each burst is nested type combination successively, and such structure is than the whole strip structure of prior art middle scraper portion; Local distortion and distortion can not take place, and promptly can not hang less than ink powder owing to regional area twists perk.And, nested combination between each burst, the leakage that can not occur scraping in the powder is scraped;
2. scraping plate part is made up of each burst, even wearing and tearing appear in indivedual burst, also can change individually;
