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 toner box, the toner box and a recovery method thereof. By setting the sealing assembly at the end of the developing roller close to the sealing film pulling outlet, a sealing and fixing guide piece is inserted in the sealing assembly, and the sealing and fixing guide piece is fixed above the groove on the surface of the powder bin, so that the sealing and fixing guide piece is far away from the developing roller. A slit is formed between the sealing components on one side, allowing the sealing film to pass through the slit and lead to the exit of the sealing film pulling out opposite to the slit. Utilizing the sealing assembly can ensure that the sealing assembly is not pulled out when the sealing film is pulled, thereby stabilizing the supporting function of the sealing assembly on the developing roller, and further preventing the toner in the powder chamber from leaking from the position of the sealing assembly. When recovering the toner cartridge with the sealing assembly, the process of resetting the sealing film at the mouth of the powder bin is simple and convenient, which facilitates the recycling and manufacturing of the toner cartridge.

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...
