Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0016] Such as figure 1 , figure 2 In the shown embodiment, an improved conductive side cover of the toner cartridge includes a side cover shell 1 and a conductive copper sheet. The conductive copper sheet includes the conductive copper sheet 2 of the powder outlet knife, the conductive copper sheet 3 of the developing roller and the conductive copper sheet 4 of the powder feeding roller. The side cover shell 1 is provided with three protruding support platforms arranged in the shape of a finished product, and the contact ends of the conductive copper sheet 2 of the powder discharge knife, the conductive copper sheet 3 of the developing roller and the conductive copper sheet 4 of the powder feeding roller are respectively arranged on the three support platforms. . A connecting copper sheet 6 is arranged between the contact end of the conduc...

The invention discloses an improved selenium drum conductive side cover which comprises a side cover shell and a conductive copper sheet, wherein the conductive copper sheet comprises a powder outlet blade conductive copper sheet, a developing roller conductive copper sheet and a powder feeding roller conductive copper sheet; the side cover shell is provided with three convex supporting tables arranged in the shape of a Chinese character 'Pin'; the contact ends of the powder outlet blade conductive copper sheet, the developing roller conductive copper sheet and the powder feeding roller conductive copper sheet are respectively arranged on the three supporting tables; a connecting copper sheet is arranged between the contact end of the powder outlet blade conductive copper sheet and the contact end of the developing roller conductive copper sheet; an insulating layer is arranged on the upper surface of the contact end of the powder outlet blade conductive copper sheet. The improved selenium drum conductive side cover has the benefits that the power supply of an external power supply to a powder outlet blade is cut off; as the powder outlet blade conductive copper sheet is connected with the developing roller conductive copper sheet through the connecting copper sheet, the developing voltage is lowered, and the problem that a gear wire appears in line printing is completely solved.
Description
technical field [0001] The invention relates to a toner drum component on a laser printer, in particular to an improved conductive side cover of the toner drum. Background technique [0002] The conductive side cover of some toner cartridges integrates the conductive copper sheet of the powder outlet knife, developing roller and powder feeding roller, which is the channel for the toner cartridge and external power supply. At present, the powder-discharging knife, the developing roller and the powder-feeding roller in this type of toner cartridge are generally powered by external power sources respectively. However, in daily use, such a structure has many problems with gear lines appearing in printing. Most of the existing patent documents on the conductive side cover of the toner cartridge are for improving the clamping structure, and it is generally difficult to find a technology that can solve such problems. For example, Chinese Patent Publication No.: CN203433269U, in t...
