Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of electronic imaging photography, specifically relates to a processing box and stirring frame subassembly for image forming equipment. BACKGROUND

[0002] The processing box is a box which can be detachably installed in the main machine of the image forming equipment, and as a whole unit, the processing box comprises a powder container body for containing toner. Figure 1 And Figure 2 As shown in Figs. 1 and 2, the powder container body 100 and the powder container body cover 101 together form a closed shell, and the inside can contain toner. The powder container body 100 is provided with a powder outlet 100a, and the toner in the powder container body 100 can be transported outward through the powder outlet 100a. In order to prevent toner leakage and pollution, the processing box will usually be provided with a sealing film 102 at the powder outlet 100a before leaving the factory. The sealing film 102 is attached to the outside of the powder outlet 100a, sealing the powder outlet 100a to prevent toner from leaking out of the powder outlet 100a. One end of the sealing film 102 extends outside the powder container body 100, and when in use, the end of the sealing film 102 extending outside the powder container body 100 needs to be pulled outward to tear off the sealing film 102, so that the sealing film 102 and the outer wall of the powder outlet 100a are separated, thereby opening the powder outlet 100a, and the toner can be transported to the developing component through the powder outlet 100a. This structure of sealing the powder outlet with a sealing film requires manual tearing of the sealing film during use, which is cumbersome and inconvenient, so a processing box that is more convenient for users to use needs to be designed to reduce the degree of user operation. SUMMARY

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0005] The stirring frame subassembly of the processing box comprises a stirring frame, a stirring frame gear provided at a gear assembly end of the stirring frame, and stirring blades provided on the stirring frame. The gear assembly end comprises a first assembly part and a second assembly part located outside the first assembly part, and the outer diameter of the first assembly part is larger than that of the second assembly part. The stirring frame gear has an assembly hole matched with the gear assembly end, and the assembly hole is a through hole with an inner diameter matched with the outer diameter of the first assembly part.

[0006] The stirring frame subassembly described above further comprises the following: during printing detection of the processing box, the stirring frame gear is sleeved on the second assembly part and can rotate freely; and during installation and use of the processing box, the stirring frame gear is sleeved on the first assembly part and can drive the stirring frame to rotate around its own axis.

[0007] The stirring frame assembly as described above, further, the second assembly portion is cylindrical.

[0008] As described above, the stirring frame assembly further has the first assembly portion having a cross-sectional shape of a polygon, and the shape of the assembly hole is adapted to the shape of the first assembly portion.

[0009] As described above, the stirring frame assembly further comprises: a limiting protrusion protruding radially along the gear assembly end is provided between the first assembly portion and the second assembly portion; and the stirring frame gear is provided with a gap corresponding to the limiting protrusion.

[0010] As described above, the stirring frame assembly, further, the cross-sectional shape of the first assembly portion is polygonal, the shape of the assembly hole is adapted to the shape of the first assembly portion; the gear assembly end is provided with a deformation seam extending along the axial direction of the gear assembly end, and the deformation seam divides the gear assembly end into two symmetrical halves.

[0011] The present utility model also provides a processing box, comprising: a powder silo body, the powder silo body having a powder outlet; and also comprising the aforementioned stirring frame assembly; the stirring frame is rotatably arranged around its own axis in the powder silo body, and the stirring blade includes a connecting portion that is snap-connected to the stirring frame and a sealing portion that seals the powder outlet.

[0012] As described above, the processing box may optionally have a plurality of snap-on posts arranged at intervals on the stirring frame, and the connecting portion of the stirring blade may have an assembly hole corresponding to the snap-on post, wherein the aperture of the assembly hole is smaller than the diameter of the snap-on post; the snap-on post is passed through the assembly hole to enable the stirring blade and the stirring frame to be snap-connected.

[0013] As described above, the processing box, optionally, the top of the buckle group is truncated cone-shaped, the bottom of the buckle column is cylindrical, the diameter of the bottom is smaller than the diameter of the top, and the aperture of the assembly hole is smaller than the diameter of the top.

[0014] As described above, in the processing box, optionally, the stirring blade is a PVC blade.

[0015] It can be seen from the above technical scheme that for the processing box that uses the stirring blade as a sealing film to seal the powder outlet, the utility model provides assembly parts with different outer diameters at the gear assembly end of the stirring frame, so that the stirring frame has different states when the stirring frame gear is assembled at different assembly ends. When performing printing inspection, the stirring frame gear is assembled on the second assembly part, and the stirring frame can rotate freely without driving the stirring frame to rotate, thereby maintaining the sealing state of the stirring blade on the powder outlet and preventing carbon powder from leaking from the powder outlet; after completing the printing inspection, the stirring frame gear is assembled on the first assembly part, and the stirring frame gear can drive the stirring frame to rotate, tearing off the stirring frame blade connected to the stirring frame from the powder outlet, releasing the seal on the powder outlet, so that the carbon powder can be transported to the developing component through the powder outlet without manual tearing, which is easy to use and meets the needs of printing inspection before the processing box leaves the factory and the need to maintain good sealing after leaving the factory.

[0032] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings. DETAILED DESCRIPTION

[0033] The present invention is described in detail below in conjunction with the accompanying drawings. When describing the embodiments of the present invention in detail, for the sake of convenience, the drawings showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. It should be noted that the drawings are simplified and use non-precise scales, which are only used to facilitate and clearly assist in explaining the purpose of the embodiments of the present invention. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated; the terms "front", "back", "bottom", "upper", "lower", "front", "back", "left", "right", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

[0034] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, it can mean a fixed connection, a detachable connection, or an integral connection; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean internal communication between two components; it can mean a wireless connection or a wired connection. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0035] In order to prevent the developer from leaking, causing pollution, and affecting the user experience, the existing processing box will use a sealing film to seal the powder outlet of the processing box before leaving the factory. The user will manually tear off the sealing film before use, and then install the processing box into a printer or other image forming device for use. In order to reduce the user's operating steps and improve the user experience, the applicant proposed a processing box (application number 2024226601140), which improved the stirring blade to be able to seal the powder outlet. Before use, the end of the stirring blade of the processing box is pasted on the powder outlet of the powder bin body to seal the powder outlet as a sealing film. After the processing box is installed and used, as the stirring frame rotates, the stirring blade is driven by the stirring frame and rotates with it. During the rotation of the stirring frame, the stirring blade can be torn off the powder outlet, so that the developer can be output from the powder outlet to achieve printing.

[0036] However, the processing box needs to be tested for printing after assembly. During the printing test, a small amount of toner is manually added to the cavity where the developing roller is located for printing test. The toner in the powder bin does not need to be used. Therefore, the stirring blade cannot be torn off from the powder outlet as a sealing film during the printing test. That is, the powder outlet must be kept in a good sealing state before the user uses it. Therefore, it is necessary to solve the problem of whether the structure that uses the stirring blade to seal the powder outlet can still maintain a sealed state after the printing test.

[0037] In response to the above problems, the utility model provides a stirring frame assembly and a processing box, which can automatically tear off the sealing film at the powder outlet when the processing box is used, reducing the user's operation steps. At the same time, the sealing film will not be torn off during printing and testing, and a good seal can be maintained.

[0038] like Figure 3 and Figure 4 As shown, the process cartridge of this embodiment includes a powder silo body 1, a powder silo body cover 2, a stirring frame 3, a stirring frame gear 4, and a stirring blade 5. When assembled, the powder silo body 1 and the powder silo body cover 2 form a closed box body that can accommodate toner. The powder silo body 1 is provided with a powder outlet 1a, through which the toner can be discharged.

[0039] The stirring frame 3 is rotatably arranged around its own axis in the powder bin body 1, and the stirring frame gear 4 is arranged at one end of the stirring frame 3. For the sake of convenience, the end of the stirring frame 3 on which the stirring frame gear is assembled is defined as the gear assembly end. The stirring frame gear 4 can rotate under the drive of an external driving force, thereby driving the stirring frame 3 to rotate around its own axis. The stirring blade 5 is arranged on the stirring frame 3 and can rotate together with the stirring frame 3. The stirring frame gear 4 of this embodiment is engaged with a double transmission gear 6, which transmits the rotational driving force of the image forming device such as a printer to the stirring frame gear 4, and drives the stirring frame 3 to rotate through the stirring frame gear 4.

[0040] The stirring blade 5 of this embodiment is a PVC blade, and the stirring blade 5 has a connecting portion 5a fixed to the stirring frame 3 and a sealing portion 5b ( Figure 4 The size of the sealing portion 5b can at least cover the powder outlet 1a. The connecting portion 5a is connected to the stirring frame 3, and the sealing portion 5b is pasted on the powder outlet 1a.

[0041] like Figure 5 As shown, when the process cartridge is not installed and used, the sealing portion 5b of the stirring blade 5 is attached to the powder outlet 1a, sealing the powder outlet 1a. This prevents toner from being transported out through the powder outlet 1a and prevents leakage. When the process cartridge is installed in the image forming apparatus and begins use, the stirring frame gear 4 receives the rotational drive force from the image forming apparatus and rotates, driving the stirring frame 3 to rotate together. The stirring frame 3 further drives the stirring blade 5 connected thereto to rotate.

[0042] like Figure 6 and Figure 7 As shown, as the stirring blade 5 rotates, it is pulled away from the powder outlet 1a. When the stirring frame 3 drives the stirring blade 5 to rotate until the sealing portion 5b completely leaves the powder outlet 1a, the powder outlet 1a is opened, allowing the toner to pass through the powder outlet 1a. After the sealing portion 5b separates from the silo wall surrounding the powder outlet 1a, it rotates within the powder silo body 1 along with the stirring frame 3, stirring the toner within the powder silo body 1 and transporting the toner through the powder outlet 1a to the developing unit, thus achieving automatic separation of the sealing structure at the powder outlet.

[0043] Since the stirring blade 5 has a sealing portion that seals the powder outlet 1a, it is wider than the conventional stirring blade (the length direction of the stirring blade is the axial direction of the stirring frame), and the PVC material is softer than the conventional PET material. When stirring the carbon powder, it has a better contact with the powder hopper body, can stir the carbon powder that contacts the inner wall of the powder hopper body, reduce the carbon powder adhering to the inner wall of the powder hopper body, reduce the residual amount of carbon powder in the powder hopper body, and improve the utilization rate of the carbon powder.

[0044] In order to prevent the stirring blade from being torn off from the powder outlet when the processing box is performing printing detection, a two-stage assembly structure is adopted between the stirring frame gear and the stirring frame in this embodiment. Figure 8 As shown, the gear assembly end 3a of the stirring frame 3 of this embodiment has a first assembly portion 3a-1 and a second assembly portion 3a-2. The second assembly portion 3a-2 is located outside the first assembly portion 3a-1 (the side closer to the midpoint of the stirring frame is the inner side, and the side farther from the midpoint of the stirring frame is the outer side). The outer diameter of the second assembly portion 3a-2 is smaller than the outer diameter of the first assembly portion 3a-1.

[0045] like Figure 9 As shown, the agitator gear 4 is machined with an assembly hole 4a that mates with the gear assembly end 3a. The assembly hole 4a is a through hole that extends through the agitator gear 4 along the axis of the agitator gear 4. The inner diameter of the assembly hole 4a matches the outer diameter of the first assembly portion 3a-1 (i.e., the inner diameter of the assembly hole 4a is larger than the outer diameter of the second assembly portion 3a-2). When the assembly hole 4a of the agitator gear 4 and the first assembly portion 3a-1 are matched together, the agitator gear 4 and the agitator 3 can be assembled together. When the agitator gear 4 is mounted on the second assembly portion 3a-2, because the outer diameter of the first assembly portion 3a-1 is larger than the outer diameter of the second assembly portion 3a-2, the inner diameter of the assembly hole 4a matches the outer diameter of the first assembly portion 3a-1, that is, the inner diameter of the assembly hole 4a is larger than the outer diameter of the second assembly portion 3a-2. Therefore, the agitator gear 4 can rotate freely when mounted on the second assembly portion 3a-2 without causing the agitator 3 to rotate with it.

[0046] Based on the above assembly structure of the stirring frame gear 4 and the stirring frame 3, when the process box is assembled and the printing test is completed, as shown in FIG. Figure 10 As shown, the stirring frame gear 4 is assembled on the second assembly part 3a-2. In this way, even if the stirring frame gear 4 is driven to rotate by the double transmission gear 6 meshing with it, it will not drive the stirring frame 3 to rotate together, thereby preventing the sealing portion 5b of the stirring blade 5 from being torn off the powder outlet 1a. After completing the printing inspection, the assembler pushes the stirring frame gear 4 inward so that the stirring frame gear 4 is sleeved on the first assembly part 3a-1. Since the inner diameter of the assembly hole 4a of the stirring frame gear 4 is adapted to the outer diameter of the first assembly part 3a-1, the assembly hole 4a and the first assembly part 3a-1 are matched together. When the stirring frame gear 4 rotates, it can drive the stirring frame 3 to rotate together, and the stirring frame 3 can operate normally.

[0047] Preferably, in order to prevent the stirring frame gear 4 from moving from the first assembly portion 3a-1 to the second assembly portion 3a-2, affecting the normal use of the process cartridge, a limiting convex portion 3a-3 is provided between the first assembly portion 3a-1 and the second assembly portion 3a-2, and the limiting convex portion 3a-3 protrudes radially along the gear assembly end 3a. Figure 9As shown, the stirring frame gear 4 is machined with gaps 4b corresponding to the limiting protrusions 3a-3. The number and shape of the gaps 4b correspond to the number and shape of the limiting protrusions 3a-3. When the stirring frame gear 4 is adjusted to the position where the gaps 4b and the limiting protrusions 3a-3 are aligned, the limiting protrusions 3a-3 can pass through the gaps 4b. At this time, the stirring frame gear 4 can be pushed inward, so that the stirring frame gear 4 moves from the second assembly part 3a-2 to the first assembly part 3a-1. The limiting protrusions 3a-3 limit the stirring frame gear 4. When the stirring frame gear 4 is mounted on the first assembly part 3a-1, the limiting protrusions 3a-3 can prevent the stirring frame gear 4 from retreating outward from the first assembly part 3a-1 to the second assembly part 3a-2. In addition to preventing the stirring frame gear 4 from sliding from the first assembly portion 3a-1 to the second assembly portion 3a-2, the limiting protrusion 3a-3 can also prevent the stirring frame gear 4 from sliding from the second assembly portion 3a-2 to the first assembly portion 3a-1.

[0048] Furthermore, in this embodiment, the cross-sectional shape of the first assembly portion 3a-1 is quadrilateral, the cross-sectional shape of the assembly hole 4a of the stirring frame gear 4 is also correspondingly quadrilateral, and the cross-sectional shape of the second assembly portion 3a-2 is circular. The polygonal shape of the first assembly portion 3a-1 and the corresponding polygonal shape of the assembly hole 4a facilitate the assembly between the first assembly portion 3a-1 and the assembly hole 4a. As long as the shapes of the two are compatible, they can be assembled together. Once the stirring frame gear 4 is mounted on the second assembly portion 3a-1, it can drive the stirring frame 3 to rotate, reducing the error requirements between the assembly dimensions and eliminating the need for high machining precision. The second assembly portion 3a-2 is cylindrical (circular in cross-sectional shape), and the inner diameter of the assembly hole 4a is also larger than the outer diameter of the second assembly portion 3a-2. When mounted on the second assembly portion 3a-2, the stirring frame gear 4 can rotate freely without driving the stirring frame 3 to rotate or tearing the sealing portion of the stirring blade from the powder outlet.

[0049] Furthermore, when the cross-sectional shape of the first assembly part 3a-1 is polygonal, such as a square, etc., in order to allow the air avoidance 4b to pass through the limiting protrusion 3a-3 and at the same time play a limiting role, the gear assembly end 3a is processed with a deformation seam 3a-4 extending along the axial direction of the gear assembly end 3a. The deformation seam 3a-4 divides the entire gear assembly end 3a (first assembly part, second assembly part) into two symmetrical halves. When the gear assembly end 3a is squeezed inward, the two symmetrical halves of the gear assembly end 3a can be slightly deformed inward, so that the air avoidance 4b can pass through the limiting protrusion 3a-3 smoothly, and restore its shape after the air avoidance 4b passes through the limiting protrusion 3a-3, so that the air avoidance 4b can no longer pass through the limiting protrusion 3a-3, and the agitator gear 4 is blocked by the limiting protrusion 3a-3, and the agitator gear cannot retreat to the second assembly part 3a-2, thereby playing a limiting role.

[0050] In other embodiments, if the cross-sectional shape of the first assembly portion is circular, that is, cylindrical, a deformation seam may not be provided. As long as the gear of the stirring rack is rotated until the positions of the avoidance and the limiting protrusion are staggered, the limiting protrusion can limit the stirring rack gear. When the avoidance and the limiting protrusion are aligned, the avoidance can pass through the limiting protrusion, thereby moving the stirring rack gear.

[0051] The following describes the process of using the process box of this embodiment in conjunction with the accompanying drawings. When the process box is assembled, the stirring frame gear 4 is installed on the second assembly part 3a-2 of the gear assembly end 3a of the stirring frame 3. Figure 4 and Figure 10 As shown, when printing detection is performed, the double transmission gear 6 and the stirring frame gear 4 are engaged. When the stirring frame gear 4 rotates under the drive of the double transmission gear 6, it idles on the second assembly part 3a-2 and does not drive the stirring frame 3 to rotate together. Before the user uses the processing cartridge, the stirring frame gear 4 is pushed inward and the stirring frame gear 4 is sleeved on the first assembly part 3a-1, as shown in FIG. Figure 11 and Figure 12 As shown, the stirring frame gear 4 and the stirring frame 3 are formally assembled together. When the double transmission gear 6 drives the stirring frame gear 4 to rotate, the stirring frame gear 4 will drive the stirring frame 3 to rotate together, and then tear the sealing part of the stirring frame blade from the powder outlet, and the developer can be transported outward from the powder outlet to achieve normal printing function.

[0052] Optionally, the stirring blade 5 of this embodiment is connected to the stirring frame 3 by a buckle. Figure 13 、 Figure 14 and Figure 15 As shown, a plurality of snap columns 7 are arranged at intervals on the stirring frame 3. The top 7a of the snap column 7 of this embodiment is truncated cone-shaped, and the bottom 7b of the snap column 7 is cylindrical, and the diameter of the bottom 7b of the snap column 7 is smaller than the diameter of the top 7a. An assembly hole a is processed on the connecting portion 5a of the stirring blade 5, and the assembly hole a and the snap column 7 are correspondingly arranged. The snap column 7 is passed through the assembly hole a to realize the snap connection between the stirring blade 5 and the stirring frame 3. The aperture of the assembly hole a is smaller than the diameter of the top 7a of the snap column 7, so that after the stirring blade 5 and the stirring frame 3 are connected, the stirring blade 5 will not fall off the stirring frame 3.

[0053] The stirring blade is connected to the stirring frame by a snap-fit ​​connection. Compared with ultrasonic welding and gluing, the assembly structure is simpler and the cost is lower. The one-piece molding of the product can better control the size and is more stable in use.

[0054] The above description of disclosed embodiments enables one of ordinary skill in the art to make or use the application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
