Detailed Description
Example one
Embodiment 1 of the present invention will be described below with reference to fig. 1 to 2. The processing box comprises a waste powder bin unit 1 and a powder bin unit 2, wherein the waste powder bin unit 1 comprises a photosensitive drum 4, a charging roller 9, a cleaning scraper 16 and the like, and the powder bin unit 2 comprises a developing roller 5, a powder feeding roller 6, a powder discharging blade 15, a developing bin 17, a powder bin 18, a stirring frame 10 and the like, and the structure is similar to that of the traditional processing box. In addition to this, the waste powder bin unit 1 has a waste powder outlet 12, a flexible waste powder collecting bag 3 containing waste powder, a peripheral wall of an inlet of the flexible waste powder collecting bag 3 being sealingly connected with a peripheral wall of the waste powder bin unit 1, and waste powder can be transferred to the flexible waste powder collecting bag 3 through the passage. In more detail, the two ends of the flexible waste toner collecting bag 3 are sealed by sealing members through sealing engagement with the injection-molded member and the ends of the photosensitive drum 4. And the axial both sides of income powder mouth of flexible waste powder collection bag 3 structure are provided with the injection molding with clean scraper 16 fixed connection to and with the spacing fixed connection's of sealing doctor-bar injection molding, and the tip of two injection moldings is connected with two tip cooperations of processing box respectively to realize the cooperation of flexible waste powder collection bag 3 and injection molding and be connected. When the carbon powder in the powder bin unit 2 of the processing box is used, the waste carbon powder enters the flexible waste powder collecting bag 3 from the photosensitive drum 4 through the cleaning of the cleaning scraper 16, and after a certain amount of the carbon powder is accumulated, the carbon powder in the powder bin 18 is pushed to move towards the developing bin 17, so that the carbon powder in the powder bin unit is more completely consumed while the carbon powder is conveyed.
