Description

Technical Field

[0001] This utility model relates to the field of powder dispensing blade technology, and in particular to a new type of high-strength toner cartridge powder dispensing blade. Background Technology

[0002] The toner ejector blade is one of the key developing components on the toner cartridge. It consists of a metal frame and a metal blade attached to the metal frame. When the toner cartridge is working, the toner ejector blade is needed to control the amount of toner ejected from the surface of the developing roller. The toner ejector blade also provides a certain pressure to the surface of the developing roller so that the toner on the surface of the developing roller is rubbed and becomes charged with sufficient charge when it passes through the metal blade.

[0003] The currently used toner blade is fixed to the corresponding position of the toner cartridge by screws to fix the metal frame. However, during use, since the metal blade is only glued to the metal frame, the glued joint is prone to cracking and lacks support. The metal blade will bend and deform during use, which will lead to uneven toner layer thickness on the surface of the developing roller and affect the normal use of the printer. 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 new type of high-strength toner drum toner discharge blade that can improve the uniformity of toner layer thickness, facilitate assembly and use, and has high stability.

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

[0006] A new type of high-strength toner cartridge dispensing blade includes a mounting frame and a metal blade. The mounting frame includes a base and a pressure plate. The metal blade is disposed between the base and the pressure plate. Mounting holes and insertion holes are formed at both ends of the pressure plate. The two ends of the base pass through the insertion holes and are bent to form bent ends. The bent ends are fitted with the pressure plate. The metal blade is welded to the base and the pressure plate. The bent ends are welded to the pressure plate.

[0007] In this way, compared to a single metal frame setup, this application uses a base and pressure plate to apply pressure to both sides of the metal blade, increasing the installation strength of the metal blade and providing support. During connection, both ends of the base pass through the insertion holes and fit against the pressure plate to form a whole, which is then welded together. Full welding can be used during welding to further improve the overall connection strength.

[0008] The pressure plate is fixedly installed with several spaced positioning cylinders, the metal blade has positioning holes that are directly opposite the positioning cylinders, and the base is fixedly installed with positioning pins that can be inserted and cooperate with the positioning cylinders.

[0009] The base is provided with a number of spaced support ribs that protrude from it. The support ribs are located below the metal blade and are in contact with the metal blade.

[0010] The pressure plate has a receiving groove that communicates with the insertion hole, and the bent end is located in the receiving groove.

[0011] The metal blade has adhesive between its two sides and the base and the pressure plate, respectively.

[0012] In summary, this high-strength new type of toner cartridge ejector blade has the advantages of improving the uniformity of toner layer thickness, facilitating assembly and use, and exhibiting high stability. Attached Figure Description

[0017] 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.

[0018] like Figure 1-4 As shown, a new type of high-strength toner cartridge dispensing blade includes a mounting frame and a metal blade 1. The mounting frame includes a base 2 and a pressure plate 3. The metal blade is disposed between the base and the pressure plate. Mounting holes 4 and insertion holes 5 are provided at both ends of the pressure plate. The two ends of the base pass through the insertion holes and are bent to form bent ends 6. The bent ends are in contact with the pressure plate. The metal blade is welded to the base and the pressure plate, and the bent ends are welded to the pressure plate.

[0019] In this way, compared to a single metal frame setup, this application uses a base and pressure plate to apply pressure to both sides of the metal blade, increasing the installation strength of the metal blade and providing support. During connection, both ends of the base pass through the insertion holes and fit against the pressure plate to form a whole, which is then welded together. Full welding can be used during welding to further improve the overall connection strength.

[0020] In practice, the pressure plate is fixedly equipped with several spaced positioning cylinders 7, the metal blade has positioning holes 8 that are directly opposite the positioning cylinders, and the base is fixedly equipped with positioning pins 9 that can be inserted and engaged with the positioning cylinders. The positioning cylinders, positioning holes, and positioning pins improve the installation accuracy of the metal blade.

[0021] In practice, the base is provided with a plurality of spaced-apart support ribs 10, which are located below and in contact with the metal blade. This facilitates the support of the metal blade.

[0022] In practice, the pressure plate has a receiving groove 11 that communicates with the insertion hole, and the bent end is located within the receiving groove. This prevents the bent end from protruding from the surface of the pressure plate, thus improving the overall shape and facilitating packaging and shipping.

[0023] In practice, adhesive is applied to both sides of the metal blade between it and the base and pressure plate, respectively, to improve the connection strength.

[0024] Specifically, the base is made of sheet metal or steel sheets and can be bent.

[0025] 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.
