Description

Technical Field

[0001] This utility model belongs to the field of toner cartridge technology, and in particular relates to a gear assembly for toner cartridges. Background Technology

[0002] In laser printers, more than 70% of the imaging components are concentrated in the toner cartridge. The print quality is actually largely determined by the toner cartridge, which not only determines the print quality but also how much money the user needs to spend during use.

[0003] Chinese patent discloses a toner cartridge gear transmission assembly (CN221650804U). The assembly includes a toner stirring shaft, a toner feeding roller, and a developing roller within the toner cartridge. A first transmission gear is mounted on the toner stirring shaft, a second transmission gear on the developing roller, and a third transmission gear on the toner feeding roller. The toner cartridge is equipped with a drive gear connected to the printer, and a linkage gear is also mounted on the cartridge. The linkage gear meshes with the first, second, and third transmission gears, respectively. The drive gear meshes with either the first, second, third, or linkage gear. When the printer drives the drive gear to rotate, it can rotate any one of the gears, thus driving all the gears to rotate together. This invention reduces the number of gears, reduces output torque, optimizes the assembly process, improves assembly efficiency, and reduces production costs. As the toner cartridge gear assembly is used, wear between the gears gradually increases, and debris flows between the gears with the lubricating oil, further increasing wear and reducing the service life of the gear assembly. Therefore, this invention provides a gear assembly for toner cartridges. Utility Model Content

[0004] The purpose of this invention is to address the problem that as gear assemblies are used for extended periods, debris increases the wear on the gears, and to propose a gear assembly for toner cartridges.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a gear assembly for a toner cartridge, comprising a toner cartridge, a protective cover fixedly installed on the side wall of the toner cartridge, an mounting cover fixedly installed on the side wall of the protective cover, a filter plate fixedly installed on the inner wall of the protective cover, and a rinsing assembly provided on the lower surface of the protective cover.

[0006] The flushing assembly includes a piston cylinder, the upper surface of which is fixedly connected to the lower surface of the protective cover. A fixed pipe is installed on the side wall of the piston cylinder, and an oil outlet pipe is installed at one end of the fixed pipe. A piston plate is slidably installed on the inner wall of the piston cylinder, and a connecting plate is fixedly installed on the side wall of the piston plate. A connecting rod is rotatably installed on the side wall of the connecting plate via a rotating shaft, and a rotating disk is rotatably installed at one end of the connecting rod via a rotating shaft.

[0007] As a further description of the above technical solution:

[0008] A movable rod is fixedly installed on the side wall of the rotating disk. A mounting plate is rotatably installed on the outer surface of the movable rod. The upper surface of the mounting plate is fixedly connected to the lower surface of the protective cover. A driven toothed sprocket is fixedly installed on the outer surface of the movable rod.

[0009] As a further description of the above technical solution:

[0010] One end of the fixed pipe extends into the interior of the protective cover, the oil outlet pipe is located inside the protective cover, and positioning plates are fixedly installed at both ends of the oil outlet pipe. One end of the positioning plate is fixedly connected to the inner side wall of the protective cover.

[0011] As a further description of the above technical solution:

[0012] A connecting pipe is installed on the upper surface of the piston cylinder, one end of which extends into the interior of the protective cover. One-way valves are fixedly installed on the inner walls of both the connecting pipe and the fixed pipe.

[0013] As a further description of the above technical solution:

[0014] A drive motor is fixedly installed on the inner wall of the mounting cover. A rotating rod is fixedly installed at the output end of the drive motor. One end of the rotating rod extends into the interior of the protective cover. A transmission gear and a drive sprocket are fixedly installed on the outer surface of the rotating rod.

[0015] As a further description of the above technical solution:

[0016] The drive sprocket is located inside the mounting cover. The drive sprocket and the driven sprocket are connected by a toothed chain drive. Several fixed gears are rotatably mounted on the inner wall of the protective cover via a rotating shaft. The side walls of the fixed gears are fixedly connected to the stirring shaft inside the toner drum. The transmission gears mesh with the fixed gears.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] 1. In this utility model, by providing a flushing component, the drive sprocket rotates, which in turn drives the driven sprocket to rotate via the toothed chain. The driven sprocket drives the movable rod to rotate on the inner wall of the mounting plate, and the movable rod drives the rotating disk to rotate. At this time, the connecting rod drives the piston plate to move back and forth inside the piston cylinder via the connecting plate. The lubricating oil filtered in the protective cover is drawn into the piston cylinder through the connecting pipe, and then the lubricating oil is transported to the oil outlet pipe through the fixed pipe. The lubricating oil is sprayed onto the gear through the oil outlet hole, so that the lubricating oil has a certain force to flush the gear assembly, clean the debris on the gear assembly, reduce the wear caused by debris on the gear assembly, and thus improve the protection of the gear assembly.

[0019] 2. In this utility model, by setting a filter plate, the lubricating oil will flow inside the gear assembly. The filter plate will filter out the debris in the lubricating oil, and the lubricating oil will fall to the bottom of the protective cover. This achieves the filtration of debris in the lubricating oil, reduces the flow of debris in the gear assembly, thereby reducing the wear between gear assemblies and improving the service life of the gear assembly.
