Abstract
The utility model discloses a novel powder control device. According to the novel powder control device, a rubber strip is arranged on a knife rest and a hard thin sheet is arranged through the rubber strip. With the adoption of the structure, the elasticity needed by powder control is guaranteed through the rubber strip, and a plane degree of a working surface of the hard thin sheet can be ensured to meet powder control requirements through the precision of the hard thin sheet, so that the powder control is uniform; and the novel powder control device has the advantages of simple structure process, short production period and low production cost.
Description
Technical field
The utility model relates to a kind of laser printer, the novel control powder device in particularly a kind of laser printer.
Background technology
Jump type developing is present monochromatic monochrome laser printer a kind of visualization way commonly used, all adopts this kind mode like HP and Canon etc.In this structure, development section divides the work principle as shown in Figure 2, and developing apparatus comprises that developing element is magnetic roller 1a, and it is formed by rotating aluminum pipe and pipe internal fixation and by the magnetic core that certain magnetic pole distributes; Also comprise control powder device 2a; Because carbon dust is selected the magnetic mono-component powder for use, so a large amount of carbon dust of magnetic roller surface meeting absorption, when turning to the powder delivery cutter position along with aluminum pipe; Carbon dust can " being scraped " become uniform one deck to adhere to the left magnetic roller surface under the effect of powder delivery cutter; Simultaneously because of friction with going up certain electric charge, when carbon dust with aluminum tube surfaces turn to the electrostatic latent image district of photosensitive drum surface over against the position time, accomplish and develop thereby the effect through electric field force is pulled to photosensitive drum surface.
In this structure, because the developer roll surface is the aluminium of hard, therefore, present structure all adopts the process structure of pasting sheet rubber on the metal knife rest, and rubber has good springiness, control powder good stability, advantages such as good operability.But; Because it is very high when developing to the uniformity requirement of carbon dust; Therefore also very high to the uniformity coefficient and the elasticity requirement of sheet rubber, the tolerance of ordinary rubber sheet thickness is in 0.05mm, and the molded technology of common rubber pattern can not reach; Can only adopt the irrigated Polyurethane through centrifugal mode moulding of getting rid of sheet, cut again and paste on the knife rest.Aforesaid way complex process, production cycle are long, and be high to the raw-material quality requirements of rubber, thereby production cost is also high.
Summary of the invention
In order to overcome the deficiency of prior art, the utility model provides a kind of technology simple, with short production cycle, the control powder device that production cost is also low.
The utility model solves the technical scheme that its technical matters adopted:
A kind of novel control powder device comprises the knife rest that is arranged in the toner cartridge, and it is characterized in that: said knife rest is provided with rubber strip, and this rubber strip is provided with hard sheet.
Said rubber strip is installed on the knife rest through the mode of pasting.
Said rubber strip is one-body molded through the mode and the knife rest of mold pressing.
Said hard sheet is installed on the rubber strip through the mode of pasting.
Said rubber strip thickness is less than 2mm.
Said knife rest is the metal knife rest.
Said hard sheet is a bonding jumper.
Said hard sheet is a polyester sheet.
The beneficial effect of the utility model is: the utility model is provided with rubber strip on knife rest; Hard sheet is set on rubber strip, in the said structure, needed elasticity when having guaranteed the control powder through rubber strip; Again the accuracy guarantee through hard sheet self flatness of workplace of hard sheet meet the requirement of control powder; Thereby it is even to control powder, and said structure technology is simple, with short production cycle, and production cost is also low.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the synoptic diagram of old structure.
Embodiment
With reference to Fig. 1, the utility model discloses a kind of novel control powder device, comprise the knife rest 1 that is arranged in the toner cartridge, said knife rest 1 is provided with rubber strip 2, and this rubber strip 2 is provided with hard sheet 3.
As shown in the figure, institute is in this specific embodiment, and rubber strip 2 adopts bonding agent to be installed on the knife rest 1 through the mode of pasting; Hard sheet 3 is installed on the rubber strip 2 through the mode of pasting; Said structure is a preferred structure, and rubber strip 2 adopts bonding agent to stick on knife rest 1 and the rubber strip 2 respectively with hard sheet 3, has both reduced process; Be convenient to again install, certainly this structure also can adopt other mounting meanss such as rubber strip through mold pressing mode and knife rest is one-body molded or employing screw retention etc.Further, knife rest 1 is a metal knife rest 1, and metal knife rest 1 has good rigidly, the advantage that intensity is high.The elastic force that produces for the deformation that makes because of rubber strip 2 can meet job requirement; Rubber strip 2 thickness are less than 2mm; Rubber strip 2 materials can be NBR, BR, EPDM, silicon rubber etc., and in present embodiment, the material of rubber strip 2 is preferably silicon rubber; Because silicon rubber has excellent comprehensive performances, like advantages such as high chemical stability, good springiness.
In this specific embodiment, hard sheet 3 materials can be PE, PP, polyester sheet etc.In present embodiment, the material of hard sheet 3 is preferably polyester sheet, because polyester sheet has advantages such as good stability, wear-resisting acid and alkali-resistance.
In this specific embodiment, hard sheet can also be bonding jumper, and bonding jumper not only machining precision is high, and carbon dust and sheet metal friction back carbon dust carried charge height, thereby can improve print quality.
The principle of work of this device is following: carbon dust is owing to receiving that the magnetic field force effect is adsorbed on aluminium sleeve 4 surface and along with 4 rotations of aluminium sleeve; Rubber strip 2 in this device contacts with aluminium sleeve 4 lines through hard sheet 3 and pushes carbon dust; Thereby carbon dust is pushed into a layer thickness less than 2mm and uniform carbon dust layer; And be with electric charge, and shift carbon dust on the photosensitive drums 5 onto through the effect of electric field force again, accomplish developing process.
Above-mentionedly just some preferred embodiments of the utility model are illustrated and describe; But the embodiment of the utility model is not restricted to the described embodiments; As long as it reaches the technique effect of the utility model with essentially identical means, all should belong to the protection domain of the utility model.
