Description

Technical Field

[0001] The utility model relates to the technical field of toner cartridges, and particularly to a toner cartridge with low cost and easy assembly. Background Art

[0002] In the manufacturing process of existing toner cartridges, in order to reduce costs and improve production efficiency, a modular production method is usually adopted. These modules are quickly assembled through an automated production line to achieve mass production. A common toner cartridge structure mainly includes a powder bin assembly, a waste powder bin assembly, and end cap assemblies installed at both ends thereof. In order to ensure accurate alignment between these components, positioning posts are designed at both ends of the powder bin assembly and the waste powder bin assembly. These positioning posts match corresponding grooves on the end cap assemblies, thereby achieving precise assembly between the components.

[0003] However, the inventor found a problem in practice: due to the limitations of the injection molding process, the positions of the positioning posts may have slight deviations. This deviation may cause the end cap assemblies to not be fully aligned when fixing the powder bin assembly and the waste powder bin assembly, and further cause looseness of the toner cartridge during use. This looseness will affect the printing quality, resulting in discontinuous or missing parts in the printed document (i.e., the "white skipping" phenomenon). Therefore, the existing positioning method has certain limitations and defects in the production process.

[0004] Therefore, it is imperative to redesign a toner cartridge with low cost and easy assembly. Summary of the Utility Model

[0005] Aiming at the defects of the above-mentioned existing technology, the utility model provides a toner cartridge with low cost and easy assembly, aiming to solve the problem of white skipping during printing caused by deviation of positioning posts in the existing toner cartridge.

[0006] To achieve the above object, the technical solution adopted by the utility model is: a toner cartridge with low cost and easy assembly, including a powder bin main body and a waste powder bin main body matched with the output end of the powder bin main body. First side cover modules are arranged at both ends of the powder bin main body, and second side cover modules are arranged at both ends of the waste powder bin main body. The first side cover module is provided with a matching inclined surface and an extension section extending from the matching inclined surface to the second side cover module. An inner positioning groove adapted to the extension section is arranged in the second side cover module. An elastic component is arranged in the extension section, one end of the elastic component is connected to the inner wall of the inner positioning groove, and the fixing holes at the corresponding positions of the extension section and the inner positioning groove are fixed by cooperation of connecting pieces.

[0007] Based on the above, the beneficial effects of a low-cost and easily assembled toner cartridge are as follows: it solves the problem of white skipping during printing caused by the deviation of the positioning posts in the prior art; specifically, the present utility model ensures the accurate alignment between the powder bin main body and the waste powder bin main body by setting an elastic positioning structure. Even if there are slight dimensional deviations during the injection molding process, these deviations can be compensated by the deformation of the elastic components. At the same time, the extension section of the first side cover module is directly adapted to the inner positioning groove of the second side cover module, avoiding the instability between the powder bin main body and the waste powder bin main body caused by the positioning deviation during the injection molding process in the original design, ensuring the printing quality and avoiding the problem of white skipping during printing.

[0008] Furthermore, the elastic component includes a positioning post and a positioning spring fitted on the positioning post. A positioning groove is provided on the extension section. The positioning post is arranged on the matching inclined surface and is located within the positioning groove.

A drum core positioning end platform is also provided on the waste powder bin gear side cover, and a drum core structure is positioned on the drum core positioning end platform.

[0013] Based on the above, the beneficial effects of the waste powder bin gear side cover are to cooperate with the powder bin gear side cover to complete the positioning of one end of the toner cartridge; the beneficial effects of the waste powder bin conductive side cover are to cooperate with the powder bin conductive side cover to complete the positioning of the other end of the toner cartridge; the beneficial effects of the inner positioning groove are to cooperate with the extension section to improve the assembly accuracy and stability; the beneficial effects of the drum core positioning end platform are to fix the drum core structure; the beneficial effects of the drum core structure are to achieve the precise transmission and distribution of toner.
