Existing these toner cartridges leave the factory and when using, the surface of photosensitive drum and charging roller all is to keep contact connection state all the time, cause photosensitive drum and charging roller to squeeze each other for a long time and easily deform, and the adsorbate on charging roller surface ( Such as paper dust) is also easy to contaminate the photosensitive drum; this will greatly reduce the print quality of the toner cartridge and shorten the service life of the toner cartridge

Embodiment Construction
[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0020] Such as Figure 1 to Figure 4 as shown in:
[0021] The structure for separating the photosensitive drum and the charging roller according to the embodiment of the present invention includes a left separating part 1 and a right separating part 2, and a left insertion hole 3 and a right insertion hole 4 arranged on the left and right sides of the toner drum shell. Wherein, the left separating part 1 and the right separating part 2 are bolts, and are inserted into the left jack 3 and the right jack 4 respectively, and are connected with the left and right ends of the charging roller 6 to supp...

The invention relates to a photosensitive drum and charging roller separation structure. The photosensitive drum and charging roller separation structure comprises a left separation part and a right separation part, as well as a left plughole and a right plughole; the left plughole and the right plughole are formed in the end faces of the left and right sides of the shell of a selenium drum; the left separation part and the right separation part both are bolts and are inserted into the left plughole and the right plughole, respectively, and therefore, bearings at the left and right two ends of the charging roller can be supported and the photosensitive drum and the charging roller can be separated from each other. In this, the photosensitive drum and the charging roller can be kept in the separated state when the selenium drum leaves the factory or in a non-used state; as a result, the photosensitive drum and the charging roller can be prevented from deformation due to mutual squeezing for a long time, and the photosensitive drum also can be protected from being polluted by objects adsorbed on the surface of the charging roller; the printing quality of the selenium drum is guaranteed and the service life of the selenium drum is longer; besides, the photosensitive drum and charging roller separation structure is simple, easy to produce and process, and low in cost.
Description
technical field [0001] The invention belongs to the technical field of toner cartridges, in particular to a structure for separating a photosensitive drum and a charging roller. Background technique [0002] At present, a photosensitive drum and a charging roller are arranged inside the toner cartridges on the market, and the bearings at both ends of the photosensitive drum and the charging roller are installed on the toner cartridge shell. Existing these toner cartridges leave the factory and when using, the surface of photosensitive drum and charging roller all is to keep contact connection state all the time, cause photosensitive drum and charging roller to squeeze each other for a long time and easily deform, and the adsorbate on charging roller surface ( Such as paper dust) is also easy to contaminate the photosensitive drum; in this way, the print quality of the toner cartridge will be greatly reduced and the service life of the toner cartridge will be shortened. Con...
