Description

Technical field

[0001] The utility model relates to a mounting structure of a toner cartridge powder scraper. [Background Technology]

[0002] In actual use, some users may experience black shadows on the printed paper after using the printer for a period of time. The main reason for this is a large amount of toner residue on the scraper surface. The solution to this problem is to disassemble the toner cartridge and clean the toner on the scraper surface. However, the toner cartridge is composed of many rollers, which is difficult to disassemble and install. In addition, the photosensitive roller is very fragile, so it is necessary to be very careful when disassembling the toner cartridge. [Utility Model Content]

[0003] The purpose of the utility model is to overcome the above problems. We provide a mounting structure for a toner cartridge scraper. The scraper with this mounting structure can clean the carbon powder on the scraper surface without disassembling the toner cartridge.

[0004] To achieve the above-mentioned purpose, the utility model provides an installation structure for a toner cartridge scraper, which includes a shell and a scraper. A mounting groove is provided inside the shell, and the two ends of the mounting groove extend to both sides of the shell. The scraper has a sliding connection portion that is slidably connected to the mounting groove. A disassembly opening is provided on one side of the shell corresponding to the position of the scraper, and the disassembly opening is for the scraper to pass through. The scraper is provided with a plug whose size matches the disassembly opening.

[0005] In one or more embodiments, the plug is provided with a pull handle outside the shell.

[0006] In one or more embodiments, the cross-section of the mounting slot is T-shaped, and the cross-section of the sliding portion is T-shaped.

[0007] In one or more embodiments, an arc-shaped transition surface is provided at the corner position of the sliding portion.

[0008] In one or more embodiments, the scraper blade includes a blade holder and a blade body, the blade holder is provided with a blade groove, a portion of the blade body is embedded in the blade groove, and the blade body is fixed to the blade holder by screws.

[0009] In one or more embodiments, the mounting slot is located above the scraping end of the scraper blade.

[0010] Compared with the background technology, the present invention has the following advantages: when the printer prints a black shadow on the paper, the scraper can be pulled out from the inside of the toner cartridge through the disassembly port without disassembling the toner cartridge, and the toner cartridge can be reinstalled after cleaning the carbon powder on the surface.

Brief Description of the Drawings

[0011] Figure 1 This is a schematic diagram of the structure of the powder scraper after installation in this embodiment;

[0012] Figure 2 This is a structural schematic diagram of the scraper blade disassembly process in this embodiment. [Specific implementation method]

[0013] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0014] See attached Figure 1-2 The present application provides an installation structure for a toner cartridge scraper, which includes a shell 1 and a scraper. A mounting slide 2 is provided inside the shell 1, and the two ends of the mounting slide extend to both sides of the shell 1. The scraper has a sliding portion 3 that is slidably connected to the mounting slide 2. With the cooperation of the sliding portion and the mounting slide, the user can easily slide and install and remove the scraper. Preferably, the mounting slide 2 is located above the scraping end of the scraper, and a disassembly opening is opened on one side of the shell corresponding to the position of the scraper. The disassembly opening is for the scraper to pass through, and a plug 4 of a size matching the disassembly opening is provided on the scraper. Through the disassembly opening, the user can remove or install the scraper, and the plug is used to seal the disassembly opening after the scraper is installed.

[0015] The plug 4 is provided with a handle 5 outside the shell. The handle can facilitate the user to pull out the scraper. The structure of the handle is "L" shape or "T" shape, which can be selected according to actual needs and is not limited here.

[0016] The cross section of the installation chute 2 is T-shaped, and the cross section of the sliding portion 3 is also T-shaped. This structure can limit the scraper blade to be slid and disassembled only along the direction of the installation chute.

[0017] The corners of the sliding portion 3 are provided with arc-shaped transition surfaces 6 , which can help the sliding portion slide more smoothly.

[0018] The scraper knife includes a knife seat 7 and a knife body 8. The knife seat is provided with a knife groove, and a part of the knife body is embedded in the knife groove. The knife body is fixed to the knife seat by screws. The use of screws for fixing has the advantages of easy installation and disassembly, which is convenient for replacing when the scraper knife is damaged.

[0019] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
