developer storage container

Abstract

The invention discloses a container for developer, which comprises a container body and a rotating shaft located in the container body; the container body is provided with a powder outlet. The rotating shaft is provided with a powder scraping sheet for scraping the carbon powder out of the powder outlet, and multiple sets of helical blade groups arranged at equal intervals along its axial direction; each helical blade group includes first blades located on both sides of the rotating shaft, The second blade; the first blade is located on the side of the second blade close to the powder outlet; the first blade and the second blade both include a straight section, and the end of the straight section is connected with a helical section; the helical section is along the circumferential direction of the inner cavity of the container Helical extension; the rotation track of the helical segment of any one first blade overlaps at least partially the rotation track of the straight segment of the adjacent second blade; Between the straight-line segment rotation tracks of the adjacent second blades. Compared with the prior art, the invention has the advantages of simple structure, fast and uniform material feeding, and less frictional heat generation.

Description

technical field [0001] The invention relates to the field of printing equipment, in particular to a developer container. Background technique [0002] The developer is generally used in electronic imaging equipment, such as printers and copiers, and the developer is generally loaded in a container, such as a toner cartridge. The current toner cartridge has a rotatable stirring shaft inside, and the stirring shaft generally plays the role of transporting toner (ie developer). Most of them have the defect of uneven feeding. In addition, the contact area between the spiral blade and the carbon powder is too large, resulting in excessive frictional heat generation between the carbon powder and the spiral blade. In addition, there is currently another solution for toner transmission: a developer container with a movable push plate, a screw working assembly is formed between the movable push plate and the rotating shaft, and when the rotating shaft rotates, the movable push plate...

Problems solved by technology

The current toner cartridge has a rotatable stirring shaft inside, and the stirring shaft generally plays the role of transporting toner (ie developer). Most of them have the defect of uneven feeding. In addition, the contact area between the spiral blade and the carbon powder is too large, resulting in excessive frictional heat generation between the carbon powder and the spiral blade.

In addition, there is currently another solution for toner transmission: a developer container with a movable push plate, a screw working assembly is formed between the movable push plate and the rotating shaft, and when the rotating shaft rotates, the movable push plate moves along the The inner cavity of the container moves to send the toner to the powder outlet; the structure of this scheme is more complicated, and during the moving process of the moving push plate, the friction between the moving push plate and the inner wall of the container is relatively large, resulting in too hot
