Abstract
The invention provides processing technology for improving the cleaning performance of a cleaning blade. The cleaning blade comprises an adhesive tape part provided with a working face contacted with the surface of a photosensitive drum. The processing technology comprises a method for cleaning the working face by using solvent-based cleaning agents capable of dissolving oil such as isopropyl alcohol. The solvent-based cleaning agents are used for processing the working face of the cleaning blade to remove foreign matters such as a release agent on the working face so as to increase the surface friction force of the working face; therefore, when the cleaning blade and the photosensitive drum work in a developer cartridge, carbon powder between the cleaning blade and the photosensitive drum cannot roll or generate other influence due to too smooth working face, so the cleaning performance of the cleaning blade is effectively improved and the print quality is effectively ensured.
Description
Technical field
The present invention relates to the laser printer technical field, particularly relate to a kind of treatment process that is used for the cleaning doctor in the laser printer developing agent box.
Background technology
Current, along with the continuous development of science and technology, the various parts technology that are used for laser printer developing agent box have obtained raising at full speed, and simultaneously, the carbon dust performance of using has at present also obtained very big improvement, and carbon powder particle is more and more littler, shape is also more and more round.Development along with the carbon dust technology; Cleaning doctor in the developer box but is faced with a great challenge and a difficult problem, and promptly the carbon dust particle diameter is more little, shape is round more, and the performance of the cleaning carbon dust of cleaning doctor is just poor more; The quality of prining just is difficult to guarantee that people just are difficult to satisfy to the requirement of output image quality.
Fig. 1 and Fig. 2 show cleaning doctor 2 in developer box with the working position of photosensitive drums 1 relation, the adhesive tape of cleaning doctor 2 is partly 22 close with photosensitive drums 1 relation in developer box.Referring to Fig. 3, cleaning doctor 2 comprises metal brandreth part 21 and adhesive tape part 22, and adhesive tape part 22 contacts through its workplace 221 and photosensitive drums 1 surface.For adhesive tape part 22, its one be PU (polyurethane) material, through the moulding of injection moulding extrusion way.Wherein, in adhesive tape partly in 22 forming processes, can residual fraction foreign matter (like oil substances such as release agents) on its workplace 221, make these workplace 221 smoother.Like this, in the course of the work, the carbon dust meeting that clips between cleaning doctor 2 and the photosensitive drums 1 produces because the workplace 221 of cleaning doctor 2 is too smooth rolls, thereby influences the clean-up performance of cleaning doctor 2, directly influences the quality of prining.
At present; Solve this type problem method one be through changing the thickness or the intensity of adhesive tape part; Make the elasticity of adhesive tape part increase, the contact pressure of photosensitive drum surface is realized, and the someone expects method that the workplace of adhesive tape part is handled as yet thereby strengthen the adhesive tape part.
Summary of the invention
The objective of the invention is to the defective to prior art, a kind of treatment process that improves cleaning performance of cleaning blade is provided, with effective assurance quality of prining.
For solving the problems of the technologies described above; Technical scheme below the present invention has adopted: design a kind of treatment process that improves cleaning performance of cleaning blade; Said cleaning doctor has comprised the adhesive tape part; This adhesive tape partly has the workplace that can contact with photosensitive drum surface, and said treatment process has comprised the clean method that the solvent-borne type detersive that utilizes the solubilized grease cleans said workplace.
Preferably, said solvent-borne type detersive is a white spirit.White spirit is a kind of a kind of petrolic solvent that from gasoline, extracts, and its formal name used at school is a normal heptane, and structural formula is CH3 (CH2) 5CH3, molecular weight 100.21; Colourless transparent liquid can be miscible with ether, acetone, chloroform, benzene and sherwood oil, water insoluble, dissolves in ethanol.White spirit effectively the dissolved oil lipid material, simultaneously can not react or damage the molecular structure of PU material again with the material of PU material.
Further, said clean method has comprised following steps: 1) pending cleaning doctor is fixed on the fixing tool, and makes said workplace up; 2) dip in a little said solvent-borne type detersive with non-dust cloth or nonwoven fabrics, and smear 3 to 5 times said workplace is unidirectional along the length direction of said adhesive tape part; 3) cleaning doctor after will smearing was placed on the ventilation more than 5 minutes, accomplished said treatment process.
Beneficial effect of the present invention is: the clean-up performance that 1) has improved cleaning doctor; 2) solved the quality problem bottleneck of prining that causes because of cleaning doctor; 3) treatment process of the present invention can be implemented under common environment, and is very convenient; 4) detersive obtains easily, and one chemical solvent shop all can be buied, and cost is comparatively cheap.

Fig. 2 is the cross-sectional view of fit structure shown in Figure 1.
Fig. 3 is the stereographic map of the cleaning doctor in the middle of Fig. 1.
Embodiment
A kind of embodiment of treatment process of the present invention is to utilize white spirit that the workplace of adhesive tape part is cleaned, and mainly comprises following steps: 1) pending cleaning doctor is fixed on the fixing tool, and makes its workplace up; 2) dip in a little white spirit with non-dust cloth or nonwoven fabrics, and smear 3 to 5 times workplace is unidirectional along the length direction of adhesive tape part; 3) cleaning doctor after will smearing was placed on the ventilation more than 5 minutes, accomplished said treatment process.
Utilization of the present invention is handled the workplace 221 of cleaning doctor 2 such as the solvent-borne type detersive of white appliances wet goods solubilized grease; Remove the foreign matters such as release agent on the workplace 221; To increase the skin-friction force of workplace 221; Like this when cleaning doctor 2 and photosensitive drums 1 are worked in developer box; Carbon dust between cleaning doctor 2 and the photosensitive drums 1 is can be because of the workplace 221 of cleaning doctor 2 too smoothless and produce and roll or produce other influence, thereby has improved the clean-up performance of cleaning doctor 2 effectively, has effectively guaranteed the quality of prining.
Above-described only is preferred implementation 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, and these all belong to protection scope of the present invention.
