toner container

Abstract

The invention provides a toner container, which includes a container main body, an end cap, a driving member, an annular gate member, a guide rod and a protective cover, wherein the toner container also includes a positioning cover, which is arranged in a cylindrical shape with a bottom for positioning The bottom wall of the cover is provided with a through hole, the cylindrical part passes through the through hole, the positioning cover can be slidably set outside the end cover along the cylindrical part, and the positioning cover is provided with an annular gate on the second end surface located outside the opening. The fixed part adjacent to the piece, the positioning cover is also provided with a first lock part, and the bottom wall of the protective cover is provided with a fixed column facing inward. the second locking part. Through the fixed fit between the positioning cover, the protective cover and the ring gate, there is no mechanical loss or attenuation of elastic force, and the airtightness of the powder outlet can be guaranteed even during the bumpy transportation process, which is conducive to improving the airtight performance of the toner container .

Description

technical field [0001] The invention relates to the field of electrophotographic imaging, in particular to a toner container for supplying toner to electrophotographic imaging equipment. Background technique [0002] An electrophotographic imaging device usually has an image processing unit and a developing unit, and uses developer such as toner provided by the developing unit to develop the electrostatic latent image formed on the image processing unit to form a visible image on paper and other media. Wherein, toner powder is used as a consumable item and needs to be constantly replenished into the electrophotographic imaging device. Generally, a toner container containing a certain amount of toner, which is detachably mounted to the developing unit in the electrophotographic imaging device, is used to supply the developing unit with toner. [0003] refer to figure 1 and figure 2 , figure 1 and figure 2 It is an exploded view and a sectional view of a carbon powder c...

Problems solved by technology

[0008] However, because the sealing of the ring gate 16 to the powder outlet 123 mainly depends on the biasing force of the spring 17, and when the toner container is used for a long time, it will inevitably affect the elastic recovery force of the spring 17, so the carbon powder is recovered. When the toner container is regenerated, the spring 17 needs to be replaced, and the replaced spring also needs to be of higher quality, which will inevitably increase the cost of recycling or producing the toner container

In addition, when the elastic recovery force of the spring 17 was weakened, when the toner container was extracted from the imaging device, the ring gate member 16 was prone to loose sealing of the powder outlet 123, and then the toner was easily leaked. Toner leakage can also occur in the imaging device, or during bumpy transportation, causing pollution to the environment
