Description
Technical field
The present invention relates to charging roller technical fields, more particularly, to a kind of charging roller and its manufacturing process.
Background technique
Charging roller is widely used in printer, duplicator, facsimile machine field, and printer, duplicator, facsimile machine are to pass through charging
Roller forms electrostatic latent image to photosensitive drum charging, exposure, and the electrostatic latent image portion on carbon dust to photosensitive drums is then transmitted by developer roll
Point, which is transmitted to heat-shaping on paper and forms final printing character image.General it of existing charging roller includes gold
Belong to axle center and covers the conductive rubber invested outside metal axle.
Existing charging roller is all to be molded one layer of elastic layer on the surface of metal core, then the surface spraying of elastic layer again
The special insulating layer of upper one kind；However, since the combination effect between insulating layer and elastic layer is bad, if insulating layer somewhere has
One small pin hole, then the charge on one line of aperture axial direction may be arrived by pin hole to conductive layer when charging to OPC
Electrode and leak.OPC can not effectively charge, and a black line is shown as on printed product.
Therefore it needs to improve.
Summary of the invention
In view of the deficienciess of the prior art, the object of the present invention is to provide a kind of surfaces to pass through aging process, it is not easy to
The charging roller punctured by electric current.
To achieve the goals above, the technical scheme adopted by the invention is that:
The surface of a kind of charging roller, including metal core, the metal core has an elastic polyurethane layer, the elastic polyurethane layer
Surface carry out aging process by UV machine, make 60 ~ 66 ° of shore hardness of its surface, resistance is 0.1 ~ 5M Ω.
Another kind of the invention is designed to provide a kind of manufacturing process of charging roller.
To achieve the goals above, the technical scheme adopted by the invention is that:
A kind of manufacture craft of charging roller, which comprises the following steps:
(1) metal core is cleaned up, and by drying equipment by its skin drying, is put together in containing box stand-by；
(2) metal core is put into injection mold, is molded an elastic polyurethane layer on the surface of metal core；
(3) charging roller obtained in step (2) is put into UV machine, is irradiated using UV lamp to elastic polyurethane layer,
Product is constantly rotated simultaneously, and UV lamp uniform irradiation makes the surface aging of charging roller by photocuring reaction.
After adopting the above structure, the invention has the advantages that compared with the prior art, 1, charging roller of the invention,
Elastic layer selects polyurethane material, environmentally friendly odorlessness；2, it is handled using UV photocuring, forms one on the surface of elastic polyurethane layer
Sheet resistance and stable insulating layer, are greatly improved the service life of charging roller, will not lead to the problem of black line；3, production convenience,
Without spraying, improve production environment, it is more environmentally-friendly.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is overall structure diagram of the invention.
Specific embodiment
It is only below presently preferred embodiments of the present invention, is not intended to limit the scope of the present invention.
The surface of a kind of charging roller as shown in Figure 1, including metal core, the metal core has an elastic polyurethane layer,
The surface of the elastic polyurethane layer carries out aging process by UV machine, makes 60 ~ 66 ° of shore hardness of its surface, resistance is
0.1~5MΩ。
When manufacturing charging roller, metal core is cleaned up first, and is concentrated its skin drying by drying equipment
It is placed in containing box stand-by；Metal core after cleaning, drying is put into injection mold, on the surface of metal core, injection molding one is poly-
Urethane elastic layer；The charging roller that surface is molded with elastic polyurethane layer is put into UV machine, using UV lamp to polyurethane bullet
Property layer is irradiated, while product is constantly rotated, UV lamp uniform irradiation, by photocuring reaction, makes the table of charging roller
Face aging.
Charging roller of the invention, elastic layer select polyurethane material, environmentally friendly odorlessness；And by using UV photocuring
Processing forms a sheet resistance and stable insulating layer on the surface of elastic polyurethane layer, and charging roller is greatly improved uses the longevity
Life, will not lead to the problem of black line；Entire production process is very convenient, does not have to spraying process, improves the production environment in workshop, reduces
Harm to direct labor, and it is more advantageous to environmental protection.
The above is only a preferred embodiment of the present invention, for those of ordinary skill in the art, according to the present invention
Thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as to the present invention
Limitation.
