Carbon powder stirring structure and printer

Abstract

The invention relates to a carbon powder stirring structure. The carbon powder stirring structure comprises a shaft rod, a first stirring blade and a second stirring blade, wherein the shaft rod is connected between two end surfaces of a carbon powder bin in a swinging manner; the middle section of the shaft rod is continuously bent based on the plane where the first stirring piece is located, a first limiting piece is formed on the first stirring piece, and the first limiting piece tends to act upwards on the middle section of the shaft rod; the end portions of the two ends of the shaft rod are bent relative to the middle section of the shaft rod and extend based on the plane where the second stirring piece is located, the end portions of the shaft rod are clamped to the end portions of the second stirring piece, the second stirring piece is provided with a second limiting piece, and the second limiting piece tends to act downwards on the middle section of the shaft rod. The carbon powder stirring structure can realize reliable connection of the two stirring blades on the shaft rod without an additional tool. The invention relates to a printer applying the carbon powder stirring structure.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a carbon powder stirring structure, and also relates to a printer using the carbon powder stirring structure. Background technique [0002] The imaging device is the core component of the printer. The imaging device in the laser printer mainly includes the toner chamber, photosensitive drum, charging roller, and developing roller. When the laser printer is printing, the charging roller uniformly charges the surface of the photosensitive drum to obtain a certain potential on the surface of the photosensitive drum, and then the photosensitive drum is exposed to the laser beam carrying the image information, and then forms static electricity on the surface of the photosensitive drum. latent image. The toner in the toner chamber is evenly attached to the developing roller by the stirring blade and the action of the scraper. The photosensitive drum is developed by the developing rol...

AI Technical Summary

Problems solved by technology

It is so convenient to install the stirring blades on the stirring frame, which reduces the production cost of the stirring device, but the inertia is relatively large when the rotation works, it is inevitable that the tablet will be tripped, and the falling of the stirring blades is still unavoidable

At the same time, the shape of the stirring blade in this solution is simple, and it does not have a good guiding effect on the toner. Stirring for a long time will easily lead to poor supply of toner, which will lead to missing or abnormal printing images.

In addition, the stirring blade of this structure has no stirring effect on the toner at the toner outlet, which may easily cause the agglomeration of the toner at the toner outlet, which will affect the printed image

In addition, the connection between the stirring frame and the toner chamber is prone to powder leakage or frictional heat, which will cause the toner to agglomerate, resulting in abnormal printing images
