Description

Technical Field

[0001] This utility model relates to the field of laser printer technology, and in particular to a high-support printer cleaning scraper. Background Technology

[0002] During the printing process, after the toner image is transferred from the photosensitive drum to the recording paper, some toner remains on the surface of the photosensitive drum, so it is necessary to use a cleaning blade to remove the residual toner.

[0003] A typical cleaning blade consists of a blade holder and a blade. The two ends of the blade holder are fixed inside the toner cartridge with bolts, and the blade is glued to the blade holder. During use, the blade is prone to shaking, resulting in poor installation stability. This can affect the contact between the blade and the photosensitive drum, making it unable to effectively scrape off the residual toner on the photosensitive drum, causing toner leakage. Consequently, the printer will require frequent maintenance, affecting its use. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a high-support cleaning blade for printers that can increase the support strength of the blade holder, facilitate assembly and use, and further improve stability.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A high-support printer cleaning blade includes a blade holder and a blade body assembly. The blade body assembly includes a blade body, an upper clamping plate, and a lower clamping plate. The blade body is disposed between the upper clamping plate and the lower clamping plate and is fixedly connected to the upper clamping plate and the lower clamping plate. The cutting edge of the blade body is located on the outside of the upper clamping plate and the lower clamping plate.

[0007] The blade holder has L-shaped mounting ends at both ends. Several support ribs are spaced apart on the blade holder. The blade body assembly is placed on the support ribs. The upper clamp of the blade body assembly extends outward to form an extension end. The mounting end and the extension end are arranged opposite each other and have mounting holes. The mounting end and the extension end are fixedly connected to the toner cartridge by bolts.

[0008] In this way, the upper and lower clamping plates and the blade body form a blade body assembly. The upper and lower clamping plates provide a certain support for the blade body. Several support ribs are set on the blade holder. The strength and stability of the blade holder are increased by setting the support ribs. Connecting the blade body assembly to the blade holder can provide high support for the blade body, so that the blade body can better contact the photosensitive drum and scrape off the residual toner on the surface of the photosensitive drum.

[0009] The two sides of the blade body are fixedly connected to the upper clamping plate and the lower clamping plate by adhesive.

[0010] The lower clamping plate is fixed with several connecting nuts. The upper clamping plate, the blade body, and the lower clamping plate are provided with through holes that pass through the inner holes of the connecting nuts. The connecting bolts pass through the through holes and are connected to the connecting nuts by threads.

[0011] The tool holder has positioning pins fixed at both ends, and the lower clamping plate has positioning holes at both ends that are engaged with the positioning pins.

[0012] The tool holder is fixed with several locking nuts. The upper clamping plate, the tool body and the lower clamping plate are provided with through holes through the inner holes of the locking nuts. The locking bolt passes through the through holes and is connected to the locking nuts by threads.

[0013] In summary, this high-support printer cleaning blade has the advantages of increasing the strength of the blade holder support, facilitating assembly and use, and further improving stability. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. In the description of the present invention, it should be understood that directional terms such as "upper," "lower," "top," and "bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0019] like Figure 1-4 As shown, a high-support printer cleaning blade includes a blade holder 1 and a blade body assembly 2. The blade body assembly includes a blade body 3, an upper clamping plate 4, and a lower clamping plate 5. The blade body is disposed between the upper clamping plate and the lower clamping plate, and the blade body is fixedly connected to the upper clamping plate and the lower clamping plate. The cutting edge of the blade body is located on the outside of the upper clamping plate and the lower clamping plate.

[0020] The blade holder has L-shaped mounting ends at both ends. Several support ribs 6 are spaced apart on the blade holder. The blade body assembly is placed on the support ribs. The upper clamp of the blade body assembly extends outward to form an extension end. The mounting end and the extension end are arranged opposite each other and have mounting holes 7. The mounting end and the extension end are fixedly connected to the toner cartridge by bolts.

[0021] In this way, the upper and lower clamping plates and the blade body form a blade body assembly. The upper and lower clamping plates provide a certain support for the blade body. Several support ribs are set on the blade holder. The strength and stability of the blade holder are increased by setting the support ribs. Connecting the blade body assembly to the blade holder can provide high support for the blade body, so that the blade body can better contact the photosensitive drum and scrape off the residual toner on the surface of the photosensitive drum.

[0022] In practice, the two sides of the blade body are fixedly connected to the upper and lower clamping plates respectively by adhesive. This facilitates connection.

[0023] In practice, the lower clamping plate is fixed with several connecting nuts 8, and the upper clamping plate, the blade body, and the lower clamping plate are provided with through holes 9 directly opposite the inner holes of the connecting nuts. The connecting bolts pass through the through holes and are connected to the connecting nuts by threads. The cooperation between the connecting bolts and connecting nuts improves the overall integrity of the blade body assembly.

[0024] In practice, positioning pins 10 are fixed at both ends of the tool holder, and positioning holes 11 are provided at both ends of the lower clamping plate to engage with the positioning pins. This facilitates the assembly of the tool body assembly and the tool holder.

[0025] In practice, several locking nuts 12 are fixed on the tool holder. The upper clamping plate, the tool body, and the lower clamping plate are provided with through holes 13 that pass through the inner holes of the locking nuts. The locking bolt passes through the through holes and is connected to the locking nuts by threads. Before installation on the toner cartridge, the tool holder and the tool body assembly are connected to form a whole. Then, the bolt passes through the mounting hole and is connected to the toner cartridge for easy installation.

[0026] The locating pins, locking nuts, and connecting nuts are all positioned directly opposite the spacing between adjacent support ribs to avoid interference. Connecting bolts and locking bolts are not shown.

[0027] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
