Description

Technical Field

[0001] The invention relates to the field of electronic imaging equipment consumables, in particular to a carbon powder cartridge. Background Art

[0002] An electronic photographic imaging device (printing equipment) includes an image processing unit and a powder cartridge assembly, a developer supply container (toner cartridge) and the powder cartridge assembly are detachably mated, the toner cartridge contains toner (developer / toner / toner), and the toner cartridge supplies toner to the image processing unit to form a visible image on a medium such as paper.

[0003] Since toner is a consumable item, it needs to be constantly replenished in the electronic photographic imaging device, and the toner cartridge that is detachably installed in the developing unit of the electronic photographic imaging device can often only load a certain amount of toner, so the toner cartridge needs to be replaced frequently; however, the toner cartridge matching assembly needs to be used for a long time, and the toner cartridge matching assembly needs to be matched with multiple different toner cartridges during its use cycle.

[0004] A Chinese invention patent application with publication number CN106019897A discloses a toner cartridge and developer supply system, in which the container body (developer supply chamber, cartridge body) is configured as a whole to be driven to rotate by a drive receiving portion 2d (driving force receiving portion). However, since the container body loaded with toner has a large weight and a large length dimension, the rotation of the container body has a large influence on the stability of the toner cartridge as a whole, causing the toner cartridge to shake relative to the powder cartridge mating assembly.

[0005] Furthermore, the scheme of CN106019897A is provided with a coupling portion 11b on the developer receiving portion 11 (toner receiving element), and is provided with coupling portions 3b2, 3b4 (unsealing guide rails) on the toner cartridge, and the coupling portions 3b2, 3b4 are used in conjunction with the coupling portion 11b to achieve the docking of the developer receiving port 11a (powder inlet) on the toner receiving element and the powder outlet on the toner cartridge. In this scheme, when the toner cartridge moves relative to the powder cartridge mating component, the toner receiving element can shake with the toner cartridge, so that the docking of the powder inlet and the powder outlet will not be separated due to the relative movement of the toner cartridge and the powder cartridge mating component, which is helpful to ensure good docking of the powder inlet and the disposal port to a certain extent.

[0006] However, when the toner cartridge shakes relative to the powder cartridge mating assembly, friction is likely to occur between the combining parts 3b2, 3b4 and the combining part 11b, which may cause excessive wear of the combining part 11b after long-term use, resulting in the combination parts 3b2, 3b4 and the combining part 11b being unable to ensure the normal docking between the powder inlet and the powder outlet, resulting in the docking between the powder inlet and the powder outlet being prone to toner leakage; in addition, if the relative movement of the toner cartridge and the powder cartridge mating assembly is too large, it may also cause the toner receiving part to be broken, causing damage to the printing device.

[0007] In addition, the solution of CN106019897A is provided with coupling parts 3b2 and 3b4 on both sides of its end shell cover. However, once the toner cartridge is tilted relative to the electronic photographic imaging device during the installation process, the coupling part 11b may be stuck with the coupling parts 3b2 and 3b4, and the toner cartridge cannot be smoothly installed in the electronic photographic imaging device. Summary of the invention

[0008] The purpose of the present invention is to provide a toner cartridge which is not prone to causing the combined part of the toner receiving member to be worn, is not prone to toner leakage after being matched with the toner receiving member, and is conducive to the long-term normal operation of the printing device.

[0009] In order to achieve the above-mentioned purpose, the toner cartridge provided by the present invention is used to be detachably installed in an electronic photographic imaging device, the electronic photographic imaging device includes a toner receiving member slidably arranged in a vertical direction, the top of the toner receiving member has a powder inlet; the toner cartridge includes a cartridge body, a toner conveying component and an end shell cover, the toner conveying component includes a spiral conveying frame and a driving force receiving part fixedly connected to each other, the driving force receiving part is cylindrical, and a powder discharge port is provided at the bottom of the end shell cover, the cartridge body, the driving force receiving part and the end shell cover are distributed in sequence along the axial direction of the cartridge body, the inner cavity of the cartridge body, the inner cavity of the driving force receiving part and the inner cavity of the end shell cover are connected to each other, and the spiral conveying frame extends from the inner cavity of the end shell cover to the inner cavity of the cartridge body In the cavity, the toner conveying component is rotatably connected to the barrel body relative to the axis, and the toner conveying component is rotatably connected to the end shell cover relative to the axis; the toner barrel also includes a support seat fixed to the barrel body, the support seat is used to support the electronic photographic imaging device, and the support seat limits the rotation of the barrel body relative to the electronic photographic imaging device; the end shell cover has an unsealing guide rail on at least one side along the first direction, the first direction is perpendicular to the axis, and the first direction is perpendicular to the vertical direction; the unsealing guide rail has a guiding slope, the guiding slope is inclined relative to the axis, and the guiding slope extends obliquely downward from one end close to the barrel body to the end away from the barrel body; accompanying the installation operation of the toner barrel, the guiding slope guides the toner receiving part to move upward in the vertical direction.

[0010] As can be seen from the above, when the toner cartridge is installed in the electronic photographic imaging device for printing operations, the toner cartridge is not easy to shake relative to the electronic photographic imaging device, is not easy to cause friction between the unsealing guide rail and the toner receiving element on the electronic photographic imaging device, and is not easy to cause the toner receiving element to be worn, which is beneficial to ensure that the toner receiving element can maintain its original size after long-term use. In this way, after the electronic photographic imaging device has been used for a long time, the combination of the toner receiving element and the unsealing guide rail can still ensure that the powder inlet of the toner receiving element and the powder discharge port of the toner cartridge are well connected, which is beneficial to reduce the risk of toner leakage.

[0011] A preferred solution is that the end shell cover has an unsealing guide track only on one side along the first direction.

[0012] As can be seen from the above, the unsealing guide rail is not easy to get stuck when cooperating with the toner receiving member, which is conducive to ensuring that the toner cartridge can be installed normally.

[0013] Another preferred solution is that the unsealing guide rail also has an upward supporting surface, and along the axial direction, the supporting surface extends from an end of the guiding inclined surface close to the cylinder body toward one side of the cylinder body.

[0014] As can be seen from the above, the cooperation between the supporting surface and the carbon powder receiving member is more conducive to ensuring that the powder discharge port and the powder inlet are well connected.

[0015] Another preferred solution is that the number of the support seats is at least two, the support seats are distributed along the axial direction, and the support seats are located at the lower side of the carbon powder cartridge.

[0016] Another preferred solution is that the peripheral wall of the barrel body is in a smooth cylindrical shape, the spiral conveying frame has a conveying plate extending spirally around the axis, and the radial outer end of the conveying plate is slidably matched with the inner peripheral wall of the barrel body.

[0017] It can be seen from the above that the barrel body has a supporting effect on the spiral conveyor frame, which is beneficial to improving the movement stability of the spiral conveyor frame, reducing the shaking degree of the toner barrel during printing operations, and reducing the wear of the unsealing guide rail on the toner receiving component.

[0018] Another preferred solution is that the toner cartridge also includes a connecting cartridge, the cartridge cavity of the connecting cartridge passes through along the axial direction, the connecting cartridge has a first cartridge section and a second cartridge section distributed along the axial direction, the diameter of the first cartridge section is greater than the diameter of the second cartridge section, the first cartridge section is fixedly and sealingly connected to the cartridge body, and the second cartridge section is sealed and rotatably connected to the driving force receiving portion.

[0019] As can be seen from the above, the provision of the connecting cylinder facilitates the installation of the spiral conveying frame into the cylinder body from the end of the cylinder body close to the end shell cover (the positive end of the Y-axis). Of course, in other schemes of the present invention, the separate connecting cylinder can also be eliminated, and an integrally formed structure including the cylinder body and the connecting cylinder of the present scheme can be adopted as the cylinder body of the other scheme. Of course, this requires a detachable end cover to be provided at the negative end of the Y-axis of the cylinder body, and the spiral conveying frame is installed into the inner cavity of the cylinder body from the end of the cylinder body away from the end shell cover (the negative end of the Y-axis).

[0020] A further solution is that the carbon powder cartridge also includes an annular sealing gasket, which is fixedly connected to the driving force receiving part, or the annular sealing gasket is fixedly connected to the connecting barrel; the outer circumferential wall of the second barrel section is provided with a mounting convex ring, which extends along the circumference of the second barrel section; the driving force receiving part has a third barrel section and a first annular step surface extending along the circumference of the third barrel section, the first annular step surface is located on the side of the third barrel section away from the barrel body along the axial direction, the first annular step surface faces the barrel cavity of the third barrel section, the third barrel section has a cantilevered clip, along the axial direction, the end of the cantilevered clip close to the barrel body is fixedly connected to the main structure of the third barrel section, the end of the cantilevered clip away from the barrel body is the cantilevered end, and the cantilevered end protrudes into the barrel cavity of the third barrel section; the third barrel section is sleeved on the outer circumferential wall of the second barrel section, along the axial direction, the cantilevered end abuts against the wall surface of the mounting convex ring facing the first barrel section, and the annular sealing gasket is sealed and squeezed between the end surface of the second barrel section facing away from the first barrel section and the first annular step surface.

[0021] A further solution is that the inner circumferential wall surface of the first barrel section and the inner circumferential wall surface of the barrel body are located on the same cylindrical surface.

[0022] Another preferred solution is that the end of the spiral conveying frame away from the barrel body is rotatably supported on the end shell cover by means of shaft hole matching.

[0023] As can be seen from the above, this is further beneficial to improving the movement stability of the toner conveying component, further beneficial to reducing the shaking degree of the toner cartridge during the printing process, and further beneficial to reducing the wear of the unsealing guide rail on the toner receiving component.

[0024] Another preferred solution is that, along the axial direction, the end of the end shell cover away from the barrel body has an end plate, the side of the end plate away from the barrel body has a first transmission gear, the spiral conveying frame is fixedly connected to the first transmission gear, and the combination of the spiral conveying frame and the first transmission gear is rotatably supported on the end plate in a shaft hole matching manner; a stirring frame is provided at the powder discharge port, the stirring frame is rotatably connected to the end shell cover, a second transmission gear is fixed on the stirring frame, and the first transmission gear is transmission-connected to the second transmission gear.

[0025] As can be seen from the above, the rotation of the spiral conveyor frame can drive the stirring frame to rotate, which is beneficial to ensure smooth discharge of powder from the powder discharge port. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Please refer to Figure 1 , Figure 3 and Figure 5 The peripheral wall of the barrel body 1 is smooth and cylindrical, and the spiral conveying frame 31 has a conveying plate 311 that spirally extends around the axis of the barrel body 1. The radial outer end of the conveying plate 311 is slidably matched with the inner peripheral wall of the barrel body 1; and the Y-axis positive end of the spiral conveying frame 31 is rotatably supported on the end shell cover 4 by means of a shaft hole. For details, please refer to Figure 3 The end shell cover 4 has an end plate 43, the spiral conveyor frame 31 is located on the negative side of the Y-axis of the end plate 43, and the positive side of the Y-axis of the end plate 43 is also provided with a first transmission gear 7. The rotating shaft of the first transmission gear 7 passes through the end plate 43 and is fixedly connected with the spiral conveyor frame 31.

The powder discharge port of the end shell cover 4 is provided with a stirring frame 8, and the stirring frame 8 is rotatably mounted on the end shell cover 4. The positive end of the Y-axis of the stirring frame 8 is connected with a second transmission gear 9, and the second transmission gear 9 is meshed with the first transmission gear 7 for transmission. In this way, the stirring frame 8 is driven to rotate by the rotation of the spiral conveyor frame 31, which is conducive to ensuring smooth powder discharge from the powder discharge port.

[0041] Please refer to Figure 3 and Figure 4 The connecting cylinder 2 has a first cylinder section 21 and a second cylinder section 22 distributed along the positive direction of the Y-axis. The diameter of the first cylinder section 21 is larger than the diameter of the second cylinder section 22. The first cylinder section 21 is fixedly and sealedly connected to the cylinder body 1. The inner circumferential wall surface of the first cylinder section 21 and the inner circumferential wall surface of the cylinder body 1 are located on the same cylindrical surface. The second cylinder section 22 is sealed and rotatably connected to the driving force receiving part 32.

[0042] For details, please refer to Figure 3 and Figure 4The outer peripheral wall of the second barrel section 22 is provided with a mounting protrusion ring 221 , which is located at the positive end of the Y-axis of the second barrel section 22 and extends along the circumference of the second barrel section 22 .

[0043] Please refer to Figure 3 and Figure 4 The carbon powder cartridge 100 further includes an annular sealing gasket 5, which is fixedly connected to the end surface of the positive end of the second barrel section 22 in the Y-axis direction. The negative end of the driving force receiving portion 32 in the Y-axis direction has a third barrel section 321 and a first annular step surface, the first annular step surface extends along the circumference of the third barrel section 321, the first annular step surface is located on the positive side of the third barrel section 321 in the Y-axis direction, the first annular step surface faces the barrel cavity of the third barrel section 321, and the third barrel section 321 has an overhanging buckle 321 1. The overhang buckle 3211 has an overhang portion 32111 extending along the Y-axis direction and a convex portion 32112 fixedly connected to the overhang portion 32111. The negative end of the overhang portion 32111 in the Y-axis is fixedly connected to the main structure of the third barrel section 321. The positive end of the overhang portion 32111 in the Y-axis is the overhang end. The convex portion 32112 is fixedly connected to the radial inner side of the positive end of the overhang portion 32111 in the Y-axis. The convex portion 32112 protrudes into the barrel cavity of the third barrel section 321.

[0044] The third barrel section 321 is sleeved on the outer peripheral wall of the second barrel section 22 , the clamping protrusion 32112 abuts against the negative side wall of the mounting protrusion ring 221 in the Y-axis direction, and the annular sealing gasket 5 abuts against the first annular step surface in a sealing manner.

[0045] In this embodiment, when the toner cartridge is in the printing process, the annular sealing gasket 5 rubs against the first annular step surface. Optionally, in other embodiments of the present invention, the annular sealing gasket 5 may also be fixedly connected to the first annular step surface, so that when the toner cartridge is in the printing process, the annular sealing gasket 5 rubs against the end face of the positive end of the Y-axis of the second barrel section 22.

[0046] Please refer to Figure 1 A first support seat 11 is connected to the negative side of the Z axis of the barrel main body 1, and a second support seat 23 is connected to the negative side of the Z axis of the connecting barrel 2. The first support seat 11 is integrally formed with the outer peripheral wall of the barrel main body 1, and the second support seat 23 is integrally formed with the outer peripheral wall of the connecting barrel 2. Both the first support seat 11 and the second support seat 23 are used for support on the printing device. The first support seat 11 and the second support seat 23 are used to limit the rotation of the barrel main body 1 and the connecting barrel 2 relative to the printing device. The arrangement of the first support seat 11 and the second support seat 23 is further beneficial to improving the stability of the toner cartridge 100 during use, and is further beneficial to reducing the shaking of the toner cartridge 100 during use.

[0047] Specifically, the first support seat 11 is located at the negative end of the Y-axis of the barrel body 1 .

[0048] Please refer to Figure 3 and Figure 4 The rotatable connection method between the driving force receiving part 32 and the end shell cover 4 can be set with reference to the rotatable connection method between the aforementioned connecting tube 2 and the driving force receiving part 32, that is, a mounting convex ring 322 is set on the outer peripheral wall of the positive end of the Y-axis of the driving force receiving part 32, and an overhanging buckle 42 and a second annular step surface are set on the negative end tube section of the Y-axis of the end shell cover 4. The overhanging buckle 42 abuts on the negative side wall of the Y-axis of the mounting convex ring 322. An annular sealing gasket 6 is fixed on the end face of the positive end of the Y-axis of the driving force receiving part 32, and the annular sealing gasket 6 abuts on the second annular step surface. The annular sealing gasket 6 is sealed and connected between the driving force receiving part 32 and the end shell cover 4. Of course, the rotatable connection method between the driving force receiving part 32 and the end shell cover 4 can also be set with reference to the existing technologies such as CN106019897A, which will not be repeated here.

[0049] Of course, please refer to Figure 3 The outer periphery of the driving force receiving portion 32 has driving teeth 3212, and the driving teeth 3212 are used to be connected to the gear transmission of the printing device to receive the driving force from the printing device, thereby driving the toner conveying component 3 to rotate. The external structure of the driving force receiving portion 32 can be set with reference to the prior art, for example, with reference to the driving receiving part 2d of CN106019897A, which will not be repeated here.

[0050] When the toner cartridge 100 is installed in a printing device for printing operations, the toner conveying component 3 conveys the toner in the inner cavity of the cartridge body 1 to the inner cavity of the end shell cover 4 through the spiral conveying frame 31. After the toner reaches the end shell cover 4, it is discharged from the powder outlet at the bottom of the end shell cover 4 to the powder inlet of the toner receiving component 202, thereby achieving the purpose of the toner cartridge 100 supplying toner to the printing device.

[0051] When the toner cartridge 100 of the present embodiment is installed in a printing device for printing, the cartridge body 1 and the end shell cover 4 remain stationary relative to the printing device, and the toner conveying component 3 rotates relative to the cartridge body 1 and the end shell cover 4. Since the cartridge body 1 does not rotate, the stability of the toner cartridge 100 is improved, the shaking degree of the toner cartridge 100 relative to the printing device is reduced, the friction between the mating protrusion 2022 and the unsealing guide rail 41 during printing is reduced, the wear of the mating protrusion 2022 is reduced, and the mating protrusion 2022 is ensured to maintain the original size after long-term use, so that the printing device can still be used after long-term use. The powder inlet and the powder outlet are well connected by matching the protrusion 2022 with the unsealing guide rail 41 of the toner cartridge 100; and, since the toner conveying component 3 of the present embodiment can be rotatably supported by the cartridge body 1 and the connecting cartridge 2 at the negative end of the Y-axis, and the toner conveying component 3 can be rotatably supported by the end shell cover 4 at the positive end of the Y-axis, the operation of the toner conveying component 3 is relatively stable, and the rotation of the toner conveying component 3 is not likely to cause the overall shaking of the toner cartridge 100, which is further beneficial to improving the operating stability of the toner cartridge 100, and further beneficial to ensuring the powder inlet and the powder outlet are well connected by matching the protrusion 2022 with the unsealing guide rail 41.

[0052] Optionally, the end shell cover 4 of the present invention can be provided with unsealing guide rails 41 on both sides of the X-axis direction. Preferably, the end shell cover 4 has an unsealing guide rail 41 only on one of the positive side wall of the X-axis or the negative side wall of the X-axis. This can avoid the mating protrusions 2022 on both sides not being at the same horizontal position or the toner cartridge 100 being tilted during the installation process, which may cause the toner cartridge 100 to get stuck during the installation process, and is conducive to ensuring a smooth installation process of the toner cartridge 100.

[0053] Finally, it should be emphasized that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
