A developer receiving container

Abstract

The invention discloses a developer receiving container, comprising a container body, a rotating shaft located in the container body; The container body is provided with a powder outlet. The rotatingshaft is provided with a powder scraping blade for scraping the toner out of the powder outlet, and a plurality of groups of spiral blade groups arranged at equal intervals along the axial direction of the rotating shaft; Each helical blade group includes a first blade, a second blade, and a second blade on opposite sides of the rotating shaft. The first blade is positioned on a side of the secondblade adjacent to the powder outlet; The first blade and the second blade both comprise straight segments, and the ends of the straight segments are connected with spiral segments. The spiral segmentspirally extends along the circumferential direction of the inner cavity of the container; A spiral segment rotation track of any one of the first blades at least partially overlaps with a straight segment rotation track of an adjacent second blade; The rotational trajectory of the helical section of the second blade is located between the rotational trajectory of the straight section of the second blade and the rotational trajectory of the straight section of the adjacent second blade. The rotational trajectory of the helical section of the second blade is located between the rotational trajectory of the straight section of the second blade and the rotational trajectory of the adjacent straight section of the second blade. Compared with the prior art, the invention has the advantages ofsimple structure, fast and uniform material feeding, and less friction and 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
