Description

Technical Field

[0001] This utility model relates to the technical field of printer cartridges, and in particular to a cartridge that facilitates toner supply. Background Technology

[0002] Currently, when toner is transferred from the toner cartridge to the developing unit, the toner has poor flowability, resulting in toner accumulation and unstable print quality. Existing technology uses a stirring rack to stir and transfer the toner, but the stirring rack structure requires the addition of gears, which leads to high motor torque requirements and high costs. In addition, as the toner gradually decreases in the later stages of transfer, the toner has insufficient flowability, resulting in poor print quality. Utility Model Content

The developing unit is used to transport toner in the toner hopper to the surface of the photosensitive unit according to the electrostatic latent image. A toner carrier is inclinedly arranged in the toner hopper. The toner carrier is used to adjust the flow speed of the toner according to the amount of toner carried. The toner carrier is a fixedly connected deformable film or a rotatably connected movable plate. The deformable film has extensibility.

[0005] Furthermore, the powder hopper is divided into a first chamber and a second chamber by the deformable membrane, with the first chamber located above the second chamber.

[0006] Furthermore, the processing box also includes an upper sidewall and a lower sidewall, the upper sidewall being located above the lower sidewall and snapped onto the lower sidewall, and the powder hopper being formed in the upper sidewall and the lower sidewall.

[0007] Furthermore, a groove is provided on the lower sidewall, and a locking block that mates with the groove is provided on the upper sidewall.

[0008] Furthermore, one end of the movable plate is rotatably connected to the powder hopper, and an elastic element is provided between the other end of the movable plate and the bottom of the powder hopper.

[0009] Furthermore, the processing box also includes a left side wall and a right side wall, both of which have mounting holes. The left side wall and the right side wall are located on opposite sides of the movable plate. One end of the movable plate is provided with a rotating shaft, and the two ends of the rotating shaft are respectively fitted into the two mounting holes.

[0010] The beneficial effects of this utility model are:

[0024] Example 1:

[0025] like Figures 1 to 3 As shown, in this embodiment, the present invention includes a toner cartridge 1, a developing unit, and a photosensitive unit. The developing unit is used to transport toner from the toner cartridge 1 to the surface of the photosensitive unit based on the electrostatic latent image. A toner carrier is inclinedly disposed in the toner cartridge 1. The toner carrier is used to adjust the toner flow rate according to the amount of toner carried. The toner carrier is a fixedly connected deformable film 2, which has extensibility. Specifically, the developing unit transports toner from the toner cartridge 1 to the surface of the photosensitive unit based on the electrostatic latent image, and the photosensitive unit, in conjunction with the fixing assembly, transfers a predetermined image onto the printing medium, thereby completing image formation.

[0026] In contrast to the shortcomings of existing technologies, in this invention, the toner carrier portion inclined in the toner hopper 1 is a deformable film 2. The deformable film 2 has extensibility, and when the toner hopper 1 is not filled with toner, the deformable film 2 is in a straight inclined position (e.g., ...). Figure 2 As shown); when the toner cartridge 1 is in the toner-filled state, the gravity of the toner itself stretches the middle position of the deformable film 2 downward, forming a concave film state (as shown). Figure 3As shown in the diagram, when the processing box is working normally, the amount of toner gradually decreases. Due to the extensibility of the membrane, the deformable membrane 2 is pulled upward, thereby improving the flowability of the toner. Moreover, this technical solution does not require a separate stirring rack, which can reduce costs. At the same time, the tilted deformable membrane 2 can improve the flowability of the toner and ensure the stability of the printing quality. This makes the present invention have the advantages of reducing costs, improving toner flowability, and improving printing quality.

[0027] In this embodiment, the powder hopper 1 is divided into a first chamber 5 and a second chamber 6 by the deformable membrane 2, with the first chamber 5 located above the second chamber 6; the processing box further includes an upper sidewall 7 and a lower sidewall 8, with the upper sidewall 7 located above the lower sidewall 8 and snapped onto the lower sidewall 8, and the powder hopper 1 formed in the upper sidewall 7 and the lower sidewall 8; a groove 9 is provided on the lower sidewall 8, and a locking block 10 that cooperates with the groove 9 is provided on the upper sidewall 7.

[0028] Example 2:

[0029] The difference between this embodiment and Embodiment 1 lies in the specific structure of the toner carrier, as detailed below:

[0030] like Figures 4 to 5 As shown, in this embodiment, the toner carrier is a rotatably connected movable plate 3. Specifically, the flowability of the toner can be improved by directly adjusting the tilt of the movable plate 3; or, by providing an elastic element 14 between the movable plate 3 and the bottom of the toner hopper 1, the movable plate 3 can automatically adjust its tilt according to the weight of the toner.

[0031] In this embodiment, one end of the movable plate 3 is rotatably connected to the powder hopper 1, and an elastic element 14 is provided between the other end of the movable plate 3 and the bottom of the powder hopper 1; the processing box also includes a left side wall 11 and a right side wall 12, both of which have mounting holes 13. The left side wall 11 and the right side wall 12 are located on both sides of the movable plate 3, and a rotating shaft 15 is provided at one end of the movable plate 3. The two ends of the rotating shaft 15 are respectively fitted into the two mounting holes 13.

[0032] It should be noted that, since the toner carrier in the toner hopper 1 is a rotatably connected movable plate 3, when the toner hopper 1 is not filled with toner, the movable plate 3 is in an inclined position; when the toner hopper 1 is filled with toner, the movable plate 3 rotates downward due to the pressure of the toner on the elastic element 14, and the slope decreases; when the processing cartridge is working normally, the amount of toner gradually decreases, and the reaction force of the elastic element 14 causes the movable plate 3 to rotate upward, and the slope increases, so as to ensure that the amount of toner supplied is normal, thereby effectively improving the toner flowability and the stability of printing quality.

[0033] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
