Description

Technical Field

[0001] The utility model application relates to the technical field of image formation, in particular to a powder cartridge. Background Art

[0002] Electronic imaging equipment is a device that forms images on recording materials through electrophotographic imaging processing technology, such as: electronic photographic copiers, laser printers, electronic photographic printers, fax machines, word processors, etc. A toner cartridge for supplying developer (such as toner) can be detachably installed inside it. As the developer continuously participates in electronic imaging, when the developer in the toner cartridge is exhausted, the user needs to replace the toner cartridge in time or inject new developer into the toner cartridge, which makes the toner cartridge one of the frequently replaced consumable parts in electronic imaging.

[0003] In the prior art, the powder cartridge is installed and removed in a developer receiving device for receiving developer in an electronic imaging device, and each installation and removal operation of the powder cartridge in the developer receiving device involves connecting and disconnecting the powder outlet of the powder cartridge with the powder receiving port of the developer receiving device.

[0004] Figure 1 The present invention is an exploded view of a powder cartridge that can be detachably mounted on a developer receiving device disclosed in the prior art. The powder cartridge 1 comprises: a powder cartridge body 2 for containing developer, a powder discharge structure 3 located at a first end 21 in the length direction of the powder cartridge body 2, and a slide plate 4 that slides relative to the powder discharge structure 3, wherein the powder discharge structure 3 comprises an upper flange portion 3a, a lower flange portion 3b, and the powder discharge structure 3 also comprises a stirring frame 9, a powder mixing portion, a powder discharge port and other structures for discharging the developer in the powder cartridge body 2, and different structures can be designed according to different discharge principles. Figure 2a-2c middle, Figure 2a is a schematic structural diagram of a developer receiving device 8; Figure 2b is a partially enlarged cross-sectional view of the developer receiving device 8; Figure 2c The developer receiving device 8 at least includes a developer receiving portion 11, which includes a developer receiving port 11a, a coupling portion 11b for opening and closing the developer receiving port 11a, and a sealing member 13, wherein a baffle 15 located at the developer receiving port 11a is used to open and close the developer receiving port 11a, and the developer receiving port 11a and the baffle 15 are in an open and closed state by driving the developer receiving portion 11 to rise and fall through the coupling portion 11b, thereby opening and closing the developer receiving port 11a, and an elastic member 12 may also be provided to enable the coupling portion 11b to rise and fall under the elastic force of the elastic member 12. Figure 3a-3c, the guide rail structure on the lower flange portion 3b of the powder discharge structure 3 and the process of the guide rail structure being used to lift the joint portion 11b in the developer receiving device 8 to open the developer receiving port 11a of the developer receiving device 8 are shown. The guide rail structure includes a rising first portion 3b2 and a second portion 3b4. As the powder cartridge 1 is installed in the direction of arrow A, the joint portion 11b is guided to rise by the first portion 3b2, and the baffle 15 is opened at the same time, so that the developer receiving port 11a is opened, and the second portion 3b4 continues to move to the position where the powder discharge port (not shown) in the powder cartridge is fully opened, so that the powder discharge port in the powder cartridge and the developer receiving port 11a form a through developer discharge channel. In the process of disassembling the powder cartridge, similarly, when the powder cartridge 1 moves in the opposite direction B of the installation direction A, the slide plate 4 in the powder cartridge closes the powder discharge port, and the baffle 15 is closed at the same time, that is, the developer receiving port 11a is closed. However, in the process of moving the joint 11b guided by the second part 3b4 of the guide rail, since the developer receiving port 11a has been fully opened and has risen to a sufficient height, it will successively fit the corresponding parts of the bottom of the powder discharge structure 3 and the slide plate 4 and continue to move along the A / B direction with the installation / disassembly action of the powder cartridge. Even if the seal and position are aligned, relative displacement is still inevitable. Since the developer is an extremely light particulate powder, it is easy for the elastic deformation of each seal to be affected by the elastic force when the relative displacement occurs due to vibration, causing the developer to fly.

[0051] This embodiment provides a powder cartridge that can be detachably installed in an electronic imaging device. The powder cartridge of the present application is similar to the installation method of the powder cartridge of the prior art, and is also installed on the developer receiving device 8 located in the electronic imaging device, such as Figure 2a-2c .

[0052] Reference Figure 4-Figure 8 As shown, the powder barrel 1 includes a shell 7, a powder barrel body 2 and a powder discharge structure 3. The powder barrel body 2 in this embodiment is generally a long cylindrical structure. In the extension direction of the length of the powder barrel body 2, the two ends of the powder barrel body 2 are respectively a first end 21 and a second end, the first end 21 is a powder discharge end, and the powder barrel body 2 has a accommodating cavity inside for storing developer. When the powder barrel 1 is installed in an electronic imaging device, the powder barrel body 2 can be driven to rotate around its rotation axis L in the electronic imaging device. The powder discharge structure 3 is connected to the first end 21, and is used to discharge the developer in the powder barrel body 2 into the electronic imaging device to participate in the development. The shell 7 is coated on the powder discharge structure 3.

[0053] Further, Figure 6As shown, a large gear ring 22 and a small gear ring 23 are provided on the powder cartridge body 2. The large gear ring 22 can be engaged with the electronic imaging device to obtain a rotational driving force from the electronic imaging device, thereby driving the powder cartridge body 2 to rotate around its rotation axis L and relative to the powder outlet structure 3, and the small gear ring 23 rotates with the rotation of the large gear ring 22.

[0054] Further, if Figure 6 , Figure 7 As shown, the powder discharge structure 3 includes an upper flange portion 3a, a lower flange portion 3b, and a stirring frame (not shown), a powder mixing portion, a powder discharge pipe 16 and other structures for discharging the developer in the powder cylinder body 2.

A first hook 3a3 is arranged on one side close to the round shaft, which also protrudes toward the installation direction A.

[0055] In addition, refer to Fig. 9 , Fig.10 As shown, the powder discharging structure 3 further includes a gear unit 30 and a torsion spring 40; the gear unit 30 includes a coupling gear portion 31, a gear portion 32 and a support portion 33. The coupling gear portion 31 includes a first gear 311, a second gear 313 and an intermediate coupling shaft 312, the first gear 311 and the second gear 313 are respectively sleeved on both ends of the intermediate coupling shaft 312, the coupling gear portion 31 is clamped on the lower flange portion 3b, and one end thereof is connected to the first end 21 of the powder cartridge body 2, and the second gear 313 thereon is meshedly connected with the small gear ring 23 on the powder cartridge body 2, and rotates with the rotation of the small gear ring 23.

[0056] The gear part 32 is sleeved on the small diameter part 3a1 of the circular shaft, and has a gear part 322 and a toothless part 323. The gear part 322 can be meshed with the first gear 311 and rotates with the rotation of the first gear 311. However, when the toothless part 323 rotates to match the first gear 311, the gear part 32 will not receive the rotational force from the first gear 311, and the gear part 32 will stop rotating. The gear part 32 is also protrudingly provided with a second hook 321, which is arranged opposite to the first hook 3a3.

[0057] The support portion 33 is provided with a support plate 332, a communication pipe 331 and a rack 333. The support plate 332 has a first portion 332a and a second portion 332b, and the first portion 332a and the second portion 332b are vertically connected; the communication pipe 331 passes through the second portion 332b, and is cylindrical in shape, with a communication inlet 331a at one end and a communication outlet 331b at the other end. When replenishing toner, the communication inlet 331a can be connected to the powder outlet 16a on the powder outlet structure 3, and the toner flows into the developer receiving port 11a through the communication outlet 331b; the rack 333 is protrudingly arranged on the first portion 332a away from the second portion 332b. The end of the part 332b is meshed with the gear part 322 on the gear part 32; the paddles 334 are respectively arranged at both ends of the second part 332b, and are perpendicular to the second part 332b and extend in a direction parallel to the rotation axis L. The bottom of each paddle has a horizontal surface 334b ​​and an inclined surface 334a, the horizontal surface 334b ​​and the inclined surface 334a are connected, and one of the inclined surfaces 334a extends obliquely along the installation direction A, and the other inclined surface 334a extends obliquely in the opposite direction of the installation direction A.

[0058] The support portion 33 is disposed in the notch portion 3b1 of the lower flange portion 3b and can move up and down in the notch portion 3b1. The support portion 33 is at least partially disposed below the powder discharge structure 3 and can abut against the developer receiving port 11a and the baffle 15.

[0059] The torsion spring 40 is sleeved on the large diameter portion 3a2 of the circular shaft, one end of which is engaged with the first hook 3a3, and the other end is engaged with the second hook 321. When filling with carbon powder, the gear part 322 rotates with the first gear 311, and the torsion spring 40 is compressed; after filling, the gear part 322 meshes with the first gear 311 again under the action of the torsion spring 40.

[0060] Furthermore, if Fig.11 As shown, a powder outlet pipe 16 is also provided in the powder outlet structure 3. The powder outlet pipe 16 is cylindrical, and the connecting pipe 331 can be inserted in the middle thereof. A powder outlet port 16a is also provided on the side wall of the powder outlet pipe 16, which is close to the bottom of the upper flange portion 3a and can be connected with the connecting inlet 331a on the connecting pipe 331 when filling carbon powder.

[0061] Specifically, in order to better illustrate the process of joining the powder cartridge 1 with the developer receiving portion 11 of the developer receiving device 8, as shown in FIG. Fig.12A rectangular coordinate system is established in the figure, wherein the axial direction of the powder cartridge is the X-axis direction, the direction perpendicular to the axial direction X of the powder cartridge is the Y-axis direction, and the direction perpendicular to the X-axis and Y-axis directions is the Z-axis direction, wherein the installation direction of installing the powder cartridge 1 from the outside to the joint 11 is +X, and the disassembly direction is -X; the direction of the gear unit 30 pointing to the notch 3b1 is +Y, and vice versa is -Y; the rest is the Z-axis, the +Z direction is roughly upward, and the -Z direction is roughly downward.

[0062] When the powder cartridge 1 is loaded into the electronic imaging device along the +X direction, the gear unit 30 first reaches an initial state where it starts to connect with the developer receiving part 11 of the electronic imaging device. At this time, the gear unit 30 is located above the developer receiving port 11a, and the baffle 15 of the electronic imaging device located above the developer receiving port 11a is in a closed state. The gear unit 30 and the baffle 15 and the developer receiving port 11a are in a spaced state (first position), and the spring 12 of the developer receiving device 8 is in a released free state.

[0063] For more details, refer to Fig.13 As shown in the cross-sectional view, the powder outlet 16a of the powder outlet structure 3 is sealed by the connecting pipe 331 and is thus in a sealed state. Similarly, the connecting inlet 331a on the connecting pipe 331 is also sealed by the powder outlet pipe 16 and is thus in a sealed state. The paddle 334 is not in complete contact with the baffle 15, and the connecting outlet 331b is not in contact with the developer receiving port 11a. However, at this time, the axial core line of the connecting pipe 331 is roughly coaxial with the center line of the developer receiving port 11a, and the baffle 15 is also in a closed state covering the top of the developer receiving port 11a, that is, the developer receiving port 11a of the developer receiving portion 11 is in a closed state.

[0064] As the electronic imaging device starts to drive the powder cartridge 1 to rotate, the small gear ring 23 starts to rotate, driving the second gear 313 to rotate, and then the shaft gear portion 31 starts to rotate. At this time, the shaft gear portion 31 transmits the driving rotational force to the gear portion 32. The rotational force on the gear portion 32 causes the rack 333 to move downward, and the paddle 334 will slowly extend into the space between the baffles 15. The inclined surface 334a on the paddle 334 gradually contacts the baffle 15. Fig.14 , Fig.15 As shown, at this time, the paddle 334 is in a state of just contacting the baffle 15.

[0065] When the electronic imaging device drives the powder cartridge 1 to continue rotating, the rack 333 also continues to move downward, and the paddle 334 opens the baffle 15 on the electronic imaging device under the action of the inclined surface 334a, and the developer receiving port 11a is immediately opened, and then the communication pipe 331 moves downward, and its communication outlet 331b also moves downward and is inserted into the developer receiving port 11a of the developer receiving portion 11. At this time, the communication inlet 331a is connected with the powder outlet 16a (second position). Fig.17 Until the toothless portion 323 on the gear portion 32 rotates to fit with the first gear 311, the powder cartridge 1 will slip on the toothless portion 323 if it continues to rotate.

[0066] refer to Figure 18-Figure 21 , the positional relationship between the baffle 15 and the related components of the gear unit 30 is described in detail from the closed state to the open state.

[0067] The gear unit 30 includes a communication inlet 331a and a communication outlet 331b arranged relative to the communication inlet 331a in the Z direction, the communication inlet 331a contacts and cooperates with the powder outlet 16a of the powder cartridge; the communication outlet 331b contacts and cooperates with the developer receiving port 11a of the developer receiving portion 11 of the developer receiving device 8; so that the developer stored in the powder cartridge body 2 can be discharged to the developer receiving port 11a of the developer receiving device 8 through the powder outlet 16a and the communication inlet 331a and the communication outlet 331b. Fig.18 , Fig.19 As shown, in the first position, the gear unit 30 does not contact the baffle 15, that is, the inclined surface 334a and the horizontal surface 334b ​​on the paddle 334 do not contact the baffle 15. At this time, the powder outlet 16a, the communication inlet 331a, the communication outlet 331b and the developer receiving port 11a are not connected.

[0068] like Fig. 20 , Fig.21 As shown in FIG. 1 , in the second position, the baffle 15 is in an open state. At this time, the gear unit 30 contacts the baffle 15, that is, the horizontal surface 334b ​​on the paddle 334 enters the space between the two opposing baffles, and the inclined surface 334a abuts against the baffle 15 to push the baffle 15 to both sides, and the developer receiving port 11a is exposed ( Fig.17 As shown), the communication outlet 331b is inserted into the developer receiving port 11a, and at this time, the powder outlet 16a, the communication inlet 331a, the communication outlet 331b and the developer receiving port 11a are connected.

[0069] The following is a more detailed description of the continuous working process

[0070] When the powder cartridge 1 is installed into the developer receiving device 8 in the electronic imaging device, the gear unit 30 can be moved to the top of the developer receiving portion 11, and when it is continuously installed into the developer receiving device 8 along the +X direction, the gear unit 30 first moves to a position (i.e., the first position) where the axis of the connecting pipe 331 is roughly coaxial with the center line of the developer receiving port 11a, and remains stationary. When the electronic imaging device is turned on, the gear of the powder cartridge 1 is driven to rotate, thereby driving the powder cartridge 1 to rotate, and the powder cartridge 1 can work normally, the small gear ring 23 starts to rotate, driving the second gear 313 to rotate, and then the shaft gear part 31 rotates, at this time, the shaft gear part 31 transmits the driving rotational force to the gear part 32, and the rotational force on the gear part 32 causes the rack 333 to move downward, the torsion spring 40 is compressed, and the paddle 334 slowly extends into the space between the two oppositely arranged baffles 15, and the inclined surface 334a on the paddle 334 gradually contacts the baffle 15. When the electronic imaging device drives the powder cartridge 1 to continue rotating, the rack 333 continues to move downward, and the paddle 334 starts to push the baffle 15 under the action of the inclined surface 334a, so that the baffle 15 on the developer receiving device 8 rotates around its rotation axis, thereby opening the baffle 15, and the developer receiving port 11a is exposed from the baffle 15 along the +Z direction and moves a certain distance. At this time, the connecting outlet 331b moves downward to align with the developer receiving port 11a coaxially and inserts into the developer receiving port 11a of the developer receiving device 8. At this time, the connecting inlet 331a is also connected with the powder outlet 16a, so that the powder cartridge powder outlet 16a, the connecting pipe 331, and the developer receiving port 11a are coaxially aligned, so that the developer in the powder cartridge is discharged into the electronic imaging device. At this time, the toothless portion 323 on the gear portion 32 is in slipping engagement with the first gear 311.

[0071] When the developer in the powder cartridge body 2 is used up and the powder cartridge 1 needs to be taken out, the door cover (not shown) of the electronic imaging device is opened, and the powder cartridge 1 is manually rotated in the opposite direction. Under the action of the rotational force and the torsion spring 40, the gear portion 322 on the gear portion 32 engages with the first gear 311 again. Driven by the gear portion 32, the rack 333 moves upward, that is, the support portion 33 moves upward, and is disengaged from the contact between the developer receiving port 11a and the baffle 15. The gear unit 30 returns to the initial state, thereby returning the developer receiving port 11a to the initial position in the -Z direction, and the baffle 15 is closed. Then the powder cartridge 1 is taken out.

[0072] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
