Preferably, the powder bin behind the powder outlet is provided with an arc-shaped plate extending upwards, and one end of the rib, close to the arc-shaped plate, extends upwards to be attached to the front side wall surface of the arc-shaped plate.

Preferably, the rib is composed of an arc-shaped section, a first extension section connected to the front end of the arc-shaped section and a second extension section connected to the rear end of the arc-shaped section, the first extension section extends to the boss on the front side of the magnetic roller, and the second extension section extends upwards and is located on the boss on the rear side of the magnetic roller.

Preferably, the rib is integrally formed with the powder bin.

The utility model has the advantages of simple and reasonable structure, do not use the felt, improve production efficiency, compare with current technique, including the powder storehouse, be equipped with the boss that is used for bearing magnetism roller on the powder storehouse of the powder outlet left and right sides, be equipped with relatively on the boss make progress protruding with the rib that magnetism roller tip contacted, the rib leans on to form stifled powder space on the boss of inboard. The utility model discloses a set up bellied rib that makes progress and replace felt and magnetic roller to laminate mutually. Although the felt is somewhat deficient in adhesion and sealing properties with respect to the magnetic roller. However, due to the magnetic action of the magnetic roller, the carbon powder entering the powder blocking space can be coagulated to form powder blocks under the magnetic action of the magnetic roller. In this state, even if the rib and the magnetic roller are not adhered as closely as the felt, the coagulated carbon powder does not leak to the outside. And the arrangement of the ribs can reduce the installation steps of the felt and greatly improve the assembly efficiency.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

Referring to fig. 1 to 9, a felt-free powder bin structure includes a powder bin 10, bosses 110 for supporting a magnetic roller 20 are provided on the powder bin 10 on the left and right sides of a powder outlet 140, a rib 120 protruding upward relative to the bosses 110 and contacting with the end of the magnetic roller 20 is provided on the bosses 110, and a powder blocking space 150 is formed on the boss 110 on the inner side of the rib 120.

The utility model discloses a set up bellied rib that makes progress and replace felt and magnetic roller to laminate mutually. Although there is a certain lack in the adhesion and sealing properties with respect to the felt. However, due to the magnetic action of the magnetic roller, the carbon powder entering the powder blocking space can be coagulated to form powder blocks under the magnetic action of the magnetic roller. In this state, even if the rib and the magnetic roller are not adhered as closely as the felt, the coagulated carbon powder does not leak to the outside. And the arrangement of the ribs can reduce the installation steps of the felt and greatly improve the assembly efficiency.
