Powder control structure of selenium drum

Abstract

The utility model discloses a toner cartridge powder control structure which comprises a powder bin shell, a magnetic developing roller, an elastic piece and a sponge strip, the magnetic developing roller is rotatably connected in the powder bin shell, the elastic piece is connected to the powder bin shell, the sponge strip is connected to the elastic piece, and the sponge strip is connected to the magnetic developing roller. And the sponge strip is propped against the magnetic developing roller under the driving of the elastic force of the elastic piece.

The powder control durability and effectiveness of the sponge strip are improved, and the printing quality can be improved.

Description

Technical Field

[0001] The utility model relates to the technical field of toner cartridges, and particularly relates to a toner control structure for a toner cartridge. Background Art

[0002] Generally, the existing toner control structure in a toner cartridge is to arrange a sponge abutted against one side of a developing roller. After long-term use of the sponge, its elastic ability decreases, resulting in a reduction in the toner control effect on the developing roller, which easily causes black edges during printing and reduces the printing quality. Therefore, how to design a toner control structure for a toner cartridge with enhanced durability of toner control ability has become an urgent technical problem to be solved. Summary of the Utility Model

[0003] In order to overcome the existing technical defects, the purpose of the utility model is to provide a toner control structure for a toner cartridge to solve the above technical problems.

[0004] The technical solution adopted by the utility model to solve the technical problems is as follows:

[0005] According to one aspect of the utility model, a toner control structure for a toner cartridge is designed, including: a powder bin housing, a magnetic developing roller, an elastic member, and a sponge strip. The magnetic developing roller is rotatably connected to the powder bin housing. The elastic member is connected to the powder bin housing, and the sponge strip is connected to the elastic member. The sponge strip abuts against the magnetic developing roller under the elastic force of the elastic member.

[0006] By adopting the above technical solution, when the sponge strip abuts against the magnetic developing roller for a long time and the elastic force of the sponge strip decreases, the elastic member can still ensure a good abutting effect between the sponge strip and the magnetic developing roller, ensuring that the toner control effect on the magnetic developing roller is not affected, increasing the durability and effectiveness of the toner control of the sponge strip, and improving the printing quality.

[0007] In order to better solve the above technical defects, the utility model also has a better technical solution:

[0008] In some embodiments, the sponge strip has a non-porous surface, and the sponge strip abuts against the magnetic developing roller through the non-porous surface. The non-porous surface is relatively smooth and has no pores, so it can prevent the toner from clogging the pores in the sponge strip and losing its elasticity. After the magnetic developing roller contacts and presses against the non-porous surface, the non-porous surface bends and deforms to fit onto the magnetic developing roller to form a surface contact, so it is easier to scrape and disperse the toner on the magnetic developing roller evenly, improving the printing quality.

[0009] In some embodiments, the elastic member is a long strip-shaped elastic sheet.

[0010] In some embodiments, the elastic member is a long strip-shaped elastic rubber strip.

[0011] In some embodiments, the elastic member is a plurality of elastic sheets arranged at intervals in a row.

[0012] In some embodiments, the elastic member is a plurality of elastic rubber strips arranged at intervals in a row. BRIEF DESCRIPTION OF THE DRAWINGS
