Problems solved by technology

However, the contact surface between the seal under the developing roller and the powder bin is a U-shaped surface. When the sealing film is pulled, due to the large interaction force between the sealing film and the sealing, and the seal and the U-shaped surface, the developing roller The adhesive friction between them is not large, and the seal is easily pulled out from under the developing roller, which affects the overall use of the toner cartridge

Abstract

The invention provides a sealing assembly for a carbon powder box as well as the carbon powder box and a recycling method thereof. The sealing assembly is arranged at one end, close to a sealing filmpulling outlet, of a developing roller; a sealing and fixing guide sheet is inserted in the sealing assembly; the sealing and fixing guide sheet is fixedly arranged above a groove in the surface of apowder bin, so that a gap is formed between the sealing and fixing guide sheet and the sealing assembly far away from one side of the developing roller, and a sealing film penetrates out of the gap and is guided to the outside of the sealing film pulling outlet opposite to the gap. By means of the sealing assembly, the sealing assembly can be prevented from being pulled out when the sealing film is pulled, so that a supporting effect of the sealing assembly on the developing roller is stabilized, and the carbon powder in the powder bin is further prevented from leaking out of the sealing assembly. The carbon powder box with the sealing assembly is recycled, and a process of rearranging the sealing film on an opening of the powder bin is simple to operate, so that the carbon powder box canbe recycled and manufactured again conveniently.

Description

technical field [0001] The invention relates to the technical field of toner cartridges, in particular to a sealing assembly for the toner cartridge, the toner cartridge and a recycling method thereof. Background technique [0002] Toner cartridges are one of the main printing consumables in laser printers, and their recycling is increasingly valued by producers and operators. [0003] A new type of toner cartridge that is currently on the market has a sealing film installed inside the powder bin, and the sealing film is separated from the opening of the powder bin by the rotation of the stirring frame inside the powder bin. However, it is not provided with sealing film pull-out outlets on both end caps of the toner cartridge, so that when it is recycled, a new sealing film must be re-set in the powder bin before it can be sealed. Its process operation is complex and cumbersome, if it is not handled properly, it will easily lead to powder leakage from the powder bin. [00...
