Abstract
The invention relates to a repairing and regenerating method for recycling a powder-extracting knife. The powder-extracting knife comprises a knife rest and a blade, wherein the blade is in contact with a developing roller line and films are coated on the surface in the area from a contact line of a secondary blade of the blade and the developing roller to a joint of the blade and the knife rest. The repairing and regenerating method comprises the following steps: cleaning the surface of a to-be-repaired waste powder-extracting knife; measuring a distance from the contact line of the powder-extracting knife and the developing roller to the knife edge of the powder-extracting knife; cutting a knife film for the powder-extracting knife in a position where the contact line of the powder-extracting knife and the developing roller extends for a certain distance along the direction departing from the knife edge of the powder-extracting knife; and separating the knife film in the area from the knife edge of the powder-extracting knife to the cut part from the powder-extracting knife. The repairing and regenerating method provided by the invention is convenient in operation; the powder-extracting knife can be recycled and reused by performing the simple processes of measuring, scraping the knife film and removing the knife film; the generalization performance is strong; and the cost is saved and the waste is avoided.
Description
Technical field
The present invention relates to a kind of renovation process of printing consumables accessory, especially electrophotographic image forms the recycling method of the powder delivery cutter that uses in the device.
Background technology
The powder delivery cutter is the attrition component in the printing consumables, and its effect is a last powder amount of controlling carbon dust through contacting with developer roll.Concrete; When charging roller to photosensitive drum charging; The photosensitive drums exposure forms electrostatic latent image, contacts the last powder amount of control carbon dust with developer roll through the powder delivery cutter; Be sent to the electrostatic latent image part on the photosensitive drums to carbon dust, finally form the printing character image through heating and pressurizing after this carbon dust image is sent on the paper.
And after waste and old powder delivery cutter reclaims in whole industry, often occur that powder delivery cutter cutter film is aging, the cutter film scratches phenomenon, and vertical moulding can appear during these printing defects, have a strong impact on printing effect.And at present; When the powder delivery cutter reclaims, only adopt dust-free paper, non-dust cloth to be stained with inorganic or organic solvent carries out wiped clean to powder delivery cutter surface, this method can only clean powder delivery cutter surface carbon dust, foreign matter; The powder delivery cutter that causes major part to have above-mentioned defective can only be scrapped processing, causes significant wastage.
Summary of the invention
In view of this, be necessary, provide a kind of powder delivery cutter of new made recovery to obtain the recovery powder delivery cutter reparative regeneration method of utilizing again to the problem of mentioning in the background technology.
The objective of the invention is to realize through following technical scheme:
A kind of recovery powder delivery cutter reparative regeneration method; Said powder delivery cutter comprises knife rest and blade; Blade contacts with the developer roll line, and the equal overlay film of surface range from the junction of osculatory to the blade of blade and developer roll and knife rest of blade is characterized in that: may further comprise the steps:
Clean the surface of waste and old powder delivery cutter to be repaired;
Measure the distance of powder delivery cutter and developer roll osculatory to the powder delivery cutter edge of a knife, to away from powder delivery cutter edge of a knife direction extension a distance, scratch powder delivery cutter cutter film by the osculatory of powder delivery cutter and developer roll;
The powder delivery cutter edge of a knife to the cutter film of scratching part is separated from the powder delivery cutter.
To extending the 1-3cm place, scratch powder delivery cutter cutter film by powder delivery cutter and developer roll position contacting away from powder delivery cutter edge of a knife direction.
It is described that separation is to adopt to take off the separation of film instrument to the cutter film of scratching part from the powder delivery cutter with the powder delivery cutter edge of a knife.
It is described that separation is to adopt the artificial film method of taking off to separate to the cutter film of scratching part from the powder delivery cutter with the powder delivery cutter edge of a knife.
Compared to prior art, the invention has the advantages that:
The present invention is easy to operate, through simple measurement, the program that scrapes cutting die off, take off film, just can make and reclaim the powder delivery cutter and can utilize again, and generalization is strong, helps practicing thrift cost, avoids waste.

Fig. 1 is the process flow diagram of the embodiment of the invention;
Fig. 2 is powder delivery cutter and the xsect that contacts shape and the floor map of developer roll before the cutter film of scratching of the embodiment of the invention;
Fig. 3 is the planar structure synoptic diagram after the cutter film of powder delivery cutter is scratched.
Embodiment
As shown in Figure 1, a kind of recovery powder delivery cutter reparative regeneration method of present embodiment, it may further comprise the steps:
Clean the surface of waste and old powder delivery cutter 1 to be repaired: as shown in Figure 2; Powder delivery cutter 1 comprises knife rest 12 and blade 13; Blade 13 contacts with developer roll 2 lines, the equal overlay film of surface range from the junction of osculatory 3 to the blade 13 of blade 13 and developer roll 2 and knife rest 12 of blade 13;
As shown in Figure 2; Measure the distance of blade 13 with developer roll 2 osculatory 3 to the powder delivery cutter edges of a knife 11 of powder delivery cutter 1; To being that powder delivery cutter knife rest 12 directions are extended a distance 4 away from the powder delivery cutter edge of a knife 11 directions, scratch the cutter film of powder delivery cutter 1 by powder delivery cutter 1 and developer roll 2 osculatory 3;
As shown in Figure 3, with the powder delivery cutter edge of a knife 11 1 separation to the cutter film of scratching part from the powder delivery cutter.
Concrete, be by powder delivery cutter 1 and developer roll 2 osculatory 3 to extending the 1-3cm place away from the powder delivery cutter edge of a knife 11 directions, scratch the cutter film of powder delivery cutter 1.
The described cutter film of just scratching part separates to adopt from powder delivery cutter 1 takes off that the film instrument separates, and also can adopt manual type to separate.
The above embodiment has only expressed several kinds of embodiments of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with accompanying claims.
Claims (4)
1. one kind is reclaimed powder delivery cutter reparative regeneration method; Said powder delivery cutter comprises knife rest and blade; Blade contacts with the developer roll line, and the equal overlay film of surface range from the junction of osculatory to the blade of blade and developer roll and knife rest of blade is characterized in that: may further comprise the steps:
