It is made of polyurethane rubber or silicone rubber. It is also one of the main components that cause wear on the drum. Usually, the cleaning scraper is installed by fixing the positioning screws on both sides. The cross-section of the polyurethane sheet of the scraper is parallel and close to the "7"-shaped felt on the waste toner bin, so as to cooperate with the drum core. However, in the actual production and use process, it is found that whether it is manually pasted or pasted by a robot, there will be a certain deviation in the felt, which makes the felt of the toner cartridge be affected during use. There will be a certain proportion of polyurethane sheets at both ends of the cleaning scraper hanging on the side of the felt and not rebounding, causing the polyurethane sheet on the cleaning scraper to deform and warp, resulting in the drum core rotating unsmoothly, resulting in the defect of blade flipping and powder accumulation during printing. Summary of the invention

The waste powder bin plastic part is a fixed part of the outer shell of the toner cartridge. There is a shelled waste powder trough in the middle of the waste powder bin plastic part to collect waste powder, and slide grooves are provided at both ends of the upper left side of the waste powder trough; the felt seat is installed on the slide groove, and the whole is a plastic plate with a "7" shape on the top and a "bow" symmetrical plastic part on the bottom. The clamping material of the tail is a plastic with a certain elasticity, which is installed in the clamping groove of the slide groove of the waste powder bin plastic part; the felt is a "7" shaped felt with the same thickness as the polyurethane sheet, and the felt is elastic. Two pieces of felt are pasted on a toner cartridge. , respectively pasted on the corresponding "7"-shaped plastic plates on the felt seat; the cleaning scraper is composed of a metal base and a polyurethane sheet, the polyurethane sheet and the metal base are pasted in parallel to fix the relative position, and are fixed on the plastic part of the waste powder bin by screws, and the side of the polyurethane sheet of the cleaning scraper is in close contact with the side of the felt; the drum core is an organic photoconductor composed of an aluminum tube and a photosensitive material, which is installed on the plastic part in parallel with the cleaning scraper and in close contact with the polyurethane sheet of the cleaning scraper, and at the same time, a section of arc surface at both ends of the drum core is in close contact with the top surface of the felt.
[0005] Preferably, a locking groove is opened at the lower part of the slide groove, so that the felt seat can move back and forth smoothly on the slide groove.
[0006] Preferably, because the distance L1 from the lower cross-section of the "7"-shaped plastic plate of the felt seat to the upper cross-section at the top of the slide groove, the distance L2 from the upper cross-section of the bottom of the slide groove to the first cross-section of the "bow"-shaped plastic part from bottom to top is equal to the distance L3 from the positioning groove to the lower cross-section at the bottom of the slide groove, after the position of the felt seat is determined, the felt seat can be pressed down to fix the felt, thereby making the felt flush with the cleaning scraper.
[0007] When in use, first stick the felt on the "7" position corresponding to the felt seat, and then fix the cleaning scraper to the plastic part of the waste powder bin with screws, and then move the felt seat back and forth on the slide groove to ensure that the side of the felt and the side of the polyurethane sheet of the cleaning scraper are tangent and confidential. At this time, the felt can be pressed down together with the felt seat, so that the tail of the felt seat leaves the positioning slot and is finally stuck and fixed at the bottom of the slide groove. Since the thickness of the felt is the same as that of the polyurethane sheet and the felt is elastic, there is no gap on the edge of the felt after the drum core is installed in place, and the polyurethane sheet of the cleaning scraper has space to deform under force, and the upper surface of the polyurethane sheet of the cleaning scraper always remains on the same plane as the top of the felt, and there will be no situation of non-rebound resulting in blade flipping and powder accumulation.
[0008] The beneficial effect of the present invention is that the polyurethane sheet of the cleaning scraper will not be hung on the felt during the use of the toner cartridge, resulting in the situation of no rebound, blade flipping and powder accumulation. BRIEF DESCRIPTION OF THE DRAWINGS
