Description

Technical Field

[0001] The invention relates to the field of electronic imaging, and in particular to a detachable processing box installed in an imaging device. Background Art

[0002] In an image forming apparatus such as a printer using an electrophotographic image forming method (electrophotographic process), an electrophotographic photosensitive member as an image bearing member is uniformly charged, and the charged photosensitive drum is selectively exposed to form an electrostatic image on the photosensitive member. The electrostatic image formed on the photosensitive member is visualized as a toner image using a toner in a developer. The toner image formed on the photosensitive member is transferred onto a recording material such as a recording sheet or a plastic sheet, and the toner image transferred onto the recording material is fixed onto the recording material by further applying heat and pressure to the toner image, thereby implementing image recording.

[0003] The image forming apparatus generally needs to supply developer and needs to maintain various types of process cartridges. In order to conveniently supply developer and maintain various types of process cartridges, a photosensitive member, a charging unit, a developing unit, a cleaning unit, and other units are collected in a box as a frame. The process cartridge thus formed has been put into practical use, and the process cartridge is detachably attached to the main body of the image forming apparatus.

[0004] In recent years, users expect to use processing boxes with faster printing speeds and print volumes. In order to increase the printing speed and print volume, the size of the processing box will be made larger, and larger photosensitive components and developing components will be used. At the same time, the developer containing portion for storing the developer in the processing box will also become larger, and a large waste developer recovery bin will need to be added. Therefore, the torque of the processing box will become larger. In order to prevent the driving components that drive the photosensitive components and the developing components to rotate from being damaged by the large torque, or to prevent the driving head that engages with the driving components in the imaging device from being damaged, the driving components that drive the photosensitive components and the developing components in the processing box will be separately arranged to reduce the torque borne by the driving components. In addition, due to the increase in the size and weight of the processing cartridge, the traditional method of relying on the user to directly install the processing cartridge into the main body of the imaging device and remove it from the main body by hand has become very inconvenient. Therefore, the existing imaging device for installing a large processing cartridge adopts a movable tray type installation method. A movable tray is provided in the imaging device. The tray is pulled out, the processing cartridge is installed into the tray and pushed into the imaging device. When taking out the processing cartridge, the tray is also directly pulled to pull the processing cartridge out of the imaging device.

[0005] For the above-mentioned large-sized dual-drive processing box, the prior art uses a universal head drive assembly, which transmits driving force to the photosensitive component and developing component in the processing box through a pivotable universal head structure. This structure is assembled by clamping the universal head into a flange, which may cause the universal head to fall off. Summary of the invention

[0006] The purpose of the present invention is to provide a processing box to solve the technical problem in the prior art that the universal head connected by clamping is easy to fall off from the flange.

The first driving assembly also includes an adjusting component, which is used to adjust the position of the first opening. When the processing box is installed in the imaging device, the first opening always faces the first driving head in the installation direction of the processing box.

[0021] Further, a biased portion is provided on the first power receiving part, the biasing member elastically abuts against the biased portion, and the biased portion is located between the axial inner side of the first power receiving part and the axial outer side of the first power transmitting part.

[0022] Further, the second driving assembly includes a second power receiving part, and the second power receiving part is configured to be immovable in the radial direction of the second driving assembly.

[0023] Further, the direction in which the first driving power receiving part moves in the radial direction on the first driving assembly forms an angle with the direction in which the process box is taken out of the imaging device.

In this structure, the driving assembly is positioned as a whole between the main frame and the side cover of the processing box and will not fall off, and the driving force transmission is stable.

[0042] In order to make the purpose, technical solution and technical effect of the embodiments of the present invention clearer, the technical solution of the processing box of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0043] Example 1

[0044] like Figures 1 to 3 As shown, the processing box B of the present invention is detachably installed in the imaging device A, and the driving side side plate 41 and the non-driving side side plate 42 supporting the processing box B are provided in the imaging device A. The openable and closable door 43 of the imaging device is opened to allow the disassembly and assembly of the processing box B and the tray 40 can be shifted (pulled out) from the inner position (inside) of the imaging device to the outer position (outside position) of the imaging device. The processing box B is detachable along the disassembly and assembly direction E for the tray 40. The C direction is the insertion direction (installation direction) of inserting the box B into the imaging device A, and is the moving direction of the tray 40. Strictly speaking, the box B moves in a series of directions including the horizontal direction and the vertical direction, but in this embodiment, the C direction is shown as a representative insertion direction (installation direction).

[0045] like Figures 4 to 7As shown, the processing box B includes a frame 1, a photosensitive member 2 that can carry an electrostatic latent image, and a developing member (not shown in the figure) for developing the electrostatic latent image on the above-mentioned photosensitive member 2. The processing box B is provided with a first driving assembly 10 and a second driving assembly 30 at the driving end of the frame 1. The first driving assembly 10 is used to drive the photosensitive member to rotate, and the second driving assembly 30 is used to drive the developing member to rotate. The first driving assembly 10 includes a first power receiving part 14, a first power transmission part 12, an intermediate part 13, a flange 11, a sleeve 15, a bracket 16, and a pressing block 17. Among them, the first power receiving part 14 is used to engage with the first driving head 70 in the imaging device to receive the driving force, and the second driving assembly 30 includes a second power receiving part for receiving the driving force of the second driving head 80 in the imaging device. The first power receiving part 14, the first power transmission part 12, and the middle part 13 constitute a cross slider coupling, wherein the middle part 13 connects the first power receiving part 14 and the first power transmission part 12, and the first power receiving part 14 can move in the radial direction of the first driving assembly 10 relative to the first power transmission part 12. In other words, the first power receiving part 14 can move in the direction perpendicular to the rotation axis of the photosensitive member relative to the photosensitive member. The first power transmission part 12 transmits the driving force to the photosensitive member 2 through the flange 11, and a power transmission protrusion 12a is provided on the first power transmission part 12, which abuts against the force column (not shown in the figure) on the inner circle side of the flange 11, and there is a free gap between the power transmission protrusion 12a and the force column, that is, there is a free gap between the first power transmission part 12 and the flange 11, so that the first power transmission part 12 has a certain free movement space relative to the flange 11. The bracket 16 is used to support the first drive assembly 10. Specifically, the bracket 16 supports the flange 11. The bracket 16 is fixed to the frame 1 by fastening components such as self-tapping screws. A guide groove 16a is provided on the bracket 16. A sleeve piece 15 is sleeved on the first power receiving part 14. The sleeve piece 15 can be moved along the guide groove 16a along the Figure 7 The sleeve 15 moves in the M direction, and the movement of the sleeve 15 drives the first power receiving part 14 to move together with it. A pressing block 17 covers the sleeve 15 and is fixed on the bracket 16 to prevent the sleeve 15 and the first power receiving part 14 from escaping from the bracket 16. An outermost cover 18 covers the entire first drive assembly 10, and an air avoidance hole 18a is provided on the outermost cover 18, and the first power receiving part 14 passes through the air avoidance hole 18a.

[0046] When the processing box B is installed into the imaging device along the installation direction C with the tray 40, the outer side surfaces of the first drive component 10 and the second drive component 30 can force the first drive head 70 and the second drive head 80 to retract to complete the installation of the processing box. In order to increase the transmission stability and axial positioning stability of the first drive component 10 and the second drive component 30, the first power receiving part 14 and the second power receiving part are arranged to be immovable relative to the flange 11 in the direction of its own rotation axis. At the same time, this design can also greatly simplify the structure of the first drive component 10 and the second drive component 30.

[0047] When the processing box B is removed from the imaging device along the C1 direction opposite to the installation direction C along the tray 40, since a cross-section 70a is provided on the first drive head 70 in the imaging device, and the imaging device positions the first drive head 70 so that the first drive head 70 will not rotate during the process of removing the processing box B, the cross-section 70a will cause the claw of the first power receiving part 14 to be stuck on the cross-section 70a, resulting in the first drive assembly being unable to disengage from the first drive head 70. In this embodiment, the moving direction M of the first power receiving part 14 in the radial direction of the drive assembly forms an angle δ with the removal direction C1 of the processing box B. Preferably, the angle δ is set between 10 degrees and 60 degrees. When the processing box B is removed along the C1 direction, the first power receiving part 14 moves along the M direction to slide out of the stuck point with the cross-section 70a, and smoothly disengages from the first drive head. Since the second drive head 80 in the imaging device is constructed to be able to rotate freely when the processing box B is disassembled along the C1 direction, the second drive head 80 can rotate a certain angle after the second drive assembly 30 is stuck during disassembly. Therefore, the second power receiving part in the second drive assembly 30 can be set to a structure that does not move in the radial direction. Preferably, making the second power receiving part into a structure that is movable in the radial direction will make the processing box smoother during the process of taking it out of the machine.

[0048] Example 2

[0049] Next, Example 2 of the present invention is described. Figure 8 As shown, the difference between embodiment 2 of the new processing box of the present embodiment and embodiment 1 is that an adjustment mechanism for adjusting the position of the first power receiving part 14 during the installation of the processing box and a biasing mechanism for biasing the first power receiving part 14 are added to the first driving component 10.

[0050] The adjustment mechanism includes an adjustment component seat 20 and an adjustment component 19 mounted on the adjustment component seat 20. Preferably, the adjustment component mounting seat 20 is positioned by the bracket 16 and cannot be moved in the rotation direction relative to the bracket 16. A pair of first power receiving claws 14a are provided on the first power receiving portion 14. The pair of first power receiving claws 14a are arranged at intervals in the circumferential direction of the first driving component 10. The pair of first power receiving claws form a first opening 14b in the circumferential direction of the first driving component 10. The adjustment component 19 is constructed as a torsion spring structure. The torsion spring is used to adjust the position of the opening 14b. By abutting against the adjusted portion (not shown in the figure) with a non-circular cross-sectional shape provided on the first power transmission portion 12, the first opening is always facing the first driving head in the installation direction of the processing box when the processing box is installed in the imaging device.

[0051] The biasing mechanism includes a biasing member 21 mounted on the pressure block 17, and a biased portion is provided on the first driving assembly 10, specifically, a biased portion 14c is provided on the first power receiving part 14, and the biasing member 21 is elastically abutted against the biased portion 14c. Preferably, the biased portion 14c is located between the axial inner side of the first power receiving part 14 close to the inner direction of the processing box and the axial outer side of the middle part close to the outer direction of the processing box.

[0052] Preferably, an adjustment mechanism for adjusting the position of the second power receiving part during the installation of the processing box can also be added to the second driving assembly 30.

[0053] Example 3

[0054] Next, Embodiment 3 of the present invention is described. Fig. 9 As shown, the frame 1 includes a photosensitive unit frame 1a and a developing unit frame 1b. A photosensitive drum (not shown in the figure) is rotatably supported in the photosensitive unit frame 1a, and a developing roller or a magnetic roller (not shown in the figure) for developing the electrostatic latent image on the surface of the photosensitive drum is rotatably supported in the developing unit frame 1b. A first driving assembly 10 is provided at one end of the photosensitive unit frame 1a, and a second driving assembly 30 is provided at one end of the developing unit frame 1b. The first driving assembly 10 is used to drive the photosensitive drum to rotate, and the second driving assembly 30 is used to drive the developing roller to rotate.

[0055] like Figures 10 to 14As shown, the first drive assembly 10 includes a first bracket 18, a first power receiving assembly B1, and a first power transmission assembly C1. The second drive assembly 30 includes a second bracket 31, a second power receiving assembly B2, and a second power transmission assembly C2. The first power receiving assembly B1 includes a first power receiving part 14, a first movable support component 20, and a first adjustment component 19. The second power receiving assembly B2 includes a second power receiving part 32, a second movable support component 33, and a second adjustment component. The first power transmission assembly C1 includes a first power transmission component 12 and a first flange 11. The second power transmission assembly C2 includes a second power transmission component 35 and a second flange 36.

[0056] The first power receiving assembly B1 is mounted on the first bracket 18 and can move along the first bracket 18 in a direction intersecting the axis of the first flange 11. A pair of first power receiving claws 1401 are provided on the first power receiving part 14, which are used to engage with the driving head 70 in the image forming device to receive the driving force. A card slot 2001 is provided on the first movable support member 20, and a card engaging portion 2001 that can be inserted into the card slot 2001 is provided on the first power receiving part 14. The first adjusting member 19 is mounted on the first movable support member 20, and the specific first adjusting member 19 is constructed as a first torsion spring 19, and a mounting seat 2002 is provided on the first movable support member 20. The spiral main body of the first torsion spring 19 is mounted on the mounting seat 2002, and one free end thereof abuts against the first movable support member 20. When the first power receiving part 14 is mounted in the first movable support member 20, the other free end of the first torsion spring 19 is moved to abut against the adjusted portion 1402 of the first power receiving part 14. The cross-sectional shape of the regulated portion 1402 is set to be roughly elliptical. Through the abutment between the regulated portion 1402 on the first power receiving portion 14 and the first adjusting torsion spring 19, the opening direction of the opening formed between the first power receiving claws 1401 when the processing box is installed in the image forming device can face the driving head 70 in the image forming device.

[0057] A first guide sliding protrusion 1801 is arranged on the first bracket 18, and a first guide sliding groove 2001 is arranged on the first movable support component 20. The first guide sliding groove 2001 cooperates with the first guide sliding protrusion 1801, so that the first movable support component 20 can be linked with the first power receiving part 14 to move relative to the first flange 11 in a direction intersecting with the axis of the first flange 11.

[0058] The first power receiving part 14 is also provided with a first power output coupling part 1404 and a bottom protrusion 1405, and the first power receiving part coupling part 1201 cooperating with the first power output coupling part 1404 and a recess 1202 matching with the bottom protrusion 1405 are provided on the first power transmission component 12. Specifically, the first power output coupling part 1404 is an arm extending in the circumferential direction of the first power receiving part 14, and the bottom protrusion 1405 is an arc-shaped protrusion extending in the axial direction of the first power receiving part 14. The first power transmission part 12 is also provided with a power transmission protrusion 1203 and a spherical part 1204, and the first flange 11 is provided with a spherical accommodating part 1101 capable of accommodating the spherical part 1204 and a power receiving groove 1102 capable of cooperating with the power transmission protrusion 1203. The spherical portion 1204 is inserted into the spherical receiving portion 1101 and prevented from coming out of the spherical receiving portion 1101. The power transmission protrusion 1203 cooperates with the power receiving groove 1102 to transmit the driving force of the first power receiving portion 14 to the first flange 11.

[0059] like Figures 11 to 13 As shown, when the first power receiving part 14 drives the first power transmission component 12 and the first flange 11 to rotate together, the above three components are coaxial. After the first power receiving part 14 moves a distance relative to the first flange 11 along a direction intersecting the axis of the first flange 11, the first power receiving part 14 drives the first power transmission component 12 to rotate relative to the first flange 11 through the cooperation between the bottom protrusion 1405 of the first power receiving part 14 and the recess 1202. Specifically, the first power transmission component 12 rotates around the spherical receiving portion 1101 of the first flange 11, and the axis L2 of the first power transmission component 12 is inclined to the axis L1 of the first flange 11 at an angle α. At this time, the first power output coupling part 1404 and the first power receiving coupling part 1201 are disengaged, and the first power receiving part 14 will no longer drive the first power receiving coupling part 1201 to rotate when rotating, that is, the first power receiving part 14 can rotate freely relative to the first flange 11. When the first power receiving part 14 moves from the offset position offset from the axis of the first flange 11 to the coaxial position, the first power output coupling part 1404 and the first power receiving coupling part 1201 can also be re-engaged through the cooperation of the bottom end protrusion 1405 and the recess 1202.

[0060] Combine the following Fig.14 , taking the first driving assembly 10 as an example, the process of installing and removing the process cartridge of the present invention in the image forming device is described. First, as Fig.14As shown in Figures a and b, the installation direction of the processing box is parallel to the direction of the arrow X in the figure. The first adjusting component 19 can adjust the opening direction of the opening formed between a pair of first power receiving claws 1401 of the first power receiving part 14 to face the columnar front end of the drive head 70 in the image forming device. When the pair of first power receiving claws 1401 do not interfere with the power output arm 70a of the drive head 70, the pair of first power receiving claws 1401 directly pass over the front end columnar portion of the drive head 70, and the drive head 70 directly engages with the first power receiving claws 1401 after being driven by the image forming device. When the pair of first power receiving claws 1401 interfere with the power output arm 70a, the inclined structure of the outer edge of the first power receiving claws 1401 can be used to force the drive head 70 to retract a certain distance. After being driven by the image forming device, the drive head 70 will also extend and engage with the first power receiving claws 1401. When the processing box is removed from the image forming device, as shown in FIG. Fig.14 As shown in Figures b and c, as the processing box is disassembled along the direction opposite to the X direction, the drive head 70 in the image forming device drives the first power receiving part 14 to move relative to the first flange 11 while maintaining engagement with the first power receiving part 14. Subsequently, the first power receiving part 14 will be disengaged from the first power transmission component 12, and the first power receiving part 14 can rotate freely relative to the first flange 11. Even if the drive head 70 interferes with the first power receiving part 14, the free rotation characteristic of the first power receiving part 14 can be utilized to avoid the interference state through the free rotation of the first power receiving part 14, and the processing box can be smoothly taken out.

[0061] In the processing box of the present invention, the second driving component 30 adopts the same structure as the first driving component 10. The only difference is that the first driving component 10 and the second driving component 30 respectively cooperate with different driving heads in the image forming device and drive different rotating parts in the processing box to rotate. During the installation and disassembly of the processing box, the process of the second driving component 30 and the first driving component 30 engaging and disengaging with the driving head in the image forming device is the same, which will not be repeated here.

[0062] like Fig.15 As shown, preferably, a biasing member is added to both the first drive assembly 10 and the second drive assembly 30 . Fig.15 Only the schematic structure of the cross-sectional view of the first drive component 10 is shown. The first biasing member 22 is arranged between the first power transmission component 12 and the first flange 11. When the first power receiving part 14 and the first power transmission component 12 are disengaged, the first biasing member 22 can bias the first power transmission component 12 so that the axis of the first power transmission component 12 is inclined with respect to the axis of the first flange 11 and maintained in the inclined state.

[0063] In the above embodiments 1 and 2, preferably, the radially movable part of the first drive assembly is specifically set as a cross-slide coupling structure. Optionally, the middle part can also be eliminated, and the first power receiving part and the first power transmission part are directly connected by relative sliding through the guide groove and the guide sliding block.

[0064] After adopting the above technical solution, the power receiving part in the driving assembly is disengaged from the driving head in the imaging device by means of translation. In this structure, the driving assembly is positioned as a whole between the main frame and the side cover of the processing box and will not fall off, and the driving force transmission is stable.

[0065] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
