Carbon powder conveying mechanism of laser printer

Abstract

The invention relates to a carbon powder conveying mechanism of a laser printer. The conveying mechanism comprises: a powder bin box which can be independently and detachably arranged in a printer shell, is matched with a powdered ink bin of a toner cartridge main body, is communicated with the powdered ink bin, and is used for storing powdered ink and conveying the powdered ink into the powdered ink bin; a conveying part arranged in the powder bin box and used for pushing and conveying the powdered ink in the powdered ink bin box into the powdered ink bin; and a driving assembly connected with the conveying piece and drives the conveying piece to carry out powdered ink conveying action. The carbon powder conveying mechanism of the laser printer is provided with the powder bin independent of a developing roller, so that a user can conveniently fill powder or reduce the replacement cost of the powder bin by himself / herself, smooth supply of carbon powder in the printing working process can be ensured, and the conditions of powder clamping and powder leakage are avoided.

Description

technical field [0001] The invention relates to the technical field of laser printers, and also relates to a toner conveying mechanism of the laser printer. Background technique [0002] The toner cartridge mechanism used in the existing laser printer is mainly divided into an integrated toner cartridge structure and a split toner cartridge structure. The one-piece toner cartridge structure integrates the imaging unit and the developing unit in the toner cartridge, and the user needs to replace the whole toner cartridge or refill it by himself after using up the toner in the toner cartridge. Due to the many internal components of the toner cartridge, the replacement cost is high, and if the user fills the toner cartridge by himself, it is easy to cause powder jam or leakage during printing due to improper operation, which will affect the printing effect or pollute the printed image. However, in the existing split-type toner cartridge structure, the powder bin and the develo...

AI Technical Summary

Problems solved by technology

Due to the many internal components of the toner cartridge, the replacement cost is high, and if the user fills the toner cartridge by himself, it is easy to cause powder jams or leakage during printing due to improper operation, which will affect the printing effect or pollute the printed image

However, in the existing split-type toner cartridge structure, the powder bin and the developing roller are usually separated into one component. When the toner in the toner bin is used up, the powder bin and the developing roller need to be replaced at the same time, and the replacement cost is relatively high, and Usually, the toner bin and developing roller are arranged in the printer casing. When replacing the toner bin, you need to open the cover at the corresponding position on the printer, which is inconvenient to operate. You need to open the printer cover and then take out the toner bin.
