Description

Technical Field

[0001] The present invention relates to a process box which is detachably installed in an imaging device. Background Art

[0002] A process cartridge is a cartridge that can be detachably loaded into the main body of an imaging device, and the cartridge includes, as an integral unit, an electrophotographic photosensitive component and at least one of the processors such as a charger, a developer, a cleaner, etc. Since the process cartridge is detachably mounted relative to the main body of the device, it is convenient for the maintenance of the device. An electrophotographic imaging device using an electrophotographic imaging method works as follows: the electrophotographic photosensitive component uniformly charged by the charger is selectively exposed to light from the imaging device to form an electrostatic latent image, the latent image is developed into a toner image by a developer using a toner, and the formed toner image is transferred to a recording medium by a transfer device to form an image on the recording material.

[0003] In the prior art, many manufacturers use a retractable power receiving device, and a control mechanism for controlling the retraction of the power receiving device is set on one side of the processing box to achieve the engagement of the power receiving device with the drive head in the imaging device when the processing box is working, and the disengagement of the power receiving device from the drive head when the processing box is disassembled. For example, Chinese patent publication number CN102385300A discloses a control mechanism, which includes a control rod that can rotate around a fulcrum on the box body and a spring that controls the rotation of the control rod. The control mechanism can control the retraction of the power receiving part on the processing box to achieve engagement and disengagement with the machine drive drive device. In this structure, when the size of the processing box is further limited so that the retraction stroke of the above-mentioned power receiving part is limited, it will cause the power receiving part to be unable to completely disengage from the drive head in the imaging device, resulting in difficulty in removing the processing box.

[0004] In addition, Chinese patent publication number CN105843008A discloses a driving force receiving assembly for a photosensitive drum, which uses a combination of a position adjustment device and a rotation device to adjust the installation angle of the power receiving part when it is installed in the imaging device, and uses the power receiving part to swing to both sides to achieve the disengagement of the power receiving part from the driving head in the imaging device. Since the power receiving part cannot swing 360 degrees, this will result in the power receiving part not being able to swing normally at certain angles and being unable to disengage. At the same time, the power receiving part may also swing during the power transmission process, resulting in unstable power transmission. Summary of the invention

[0005] The object of the present invention is to provide a processing box to solve the technical problem in the prior art that the power receiving part in the processing box cannot normally engage and disengage with the driving head in the imaging device due to size limitations.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] A processing box is detachably installed in an imaging device having a rotatable drive head and an openable and closable machine door cover along an installation direction, and the processing box includes:

[0008] case,

[0009] A power receiving part, capable of receiving the force of the driving head;

[0010] A rotatable component, which is rotatably supported by the housing and can receive the force of the power receiving part to rotate;

[0011] The process cartridge is mounted in the image forming apparatus along an axis direction substantially perpendicular to the rotatable member.

[0012] It is characterized in that the power receiving part has a first state and a second state relative to the driving head, the first state is a state in which the power receiving part abuts against the driving head after the processing box is installed in the imaging device and the machine door cover is closed, the abutting state refers to a state in which the axis of the power receiving part is not coaxial with the axis of the driving head, the second state is a state in which the power receiving part is meshed with the driving head, the second state means that the power receiving part is approximately coaxial with the driving head and the power receiving part can receive driving force from the driving head for rotating the rotating part, and when the power receiving part is in the first state relative to the driving head, as the imaging device drives the driving head to rotate, the power receiving part can move from the first state to the second state relative to the driving head.

[0013] Furthermore, the shell is also provided with a force-bearing portion capable of receiving the machine door cover.

[0014] Furthermore, an elastic component is provided between the force-bearing portion and the shell.

[0015] Further, in the axial direction of the rotating member, no matter the power receiving portion is in the first state or the second state relative to the driving head, at least a portion of the power receiving portion overlaps with the driving head.

[0016] Furthermore, the driving head is provided with a power output arm, and when the driving head rotates, the power output arm can apply force to the power receiving part so that the power receiving part moves from a first state to a second state relative to the driving head.

[0017] Furthermore, the power receiving part is provided with a claw part which can be combined with the power output arm, and the claw part has a facing part facing the axis of the power receiving part, and when the driving head rotates, the power output arm can pass over the facing part.

[0018] Further, when the driving head rotates, the power receiving portion can force the driving head to retract in the direction of its own rotation axis.

[0019] Furthermore, a power output arm is provided on the driving head, and a claw portion which can be combined with the power output arm is provided on the power receiving portion. When the driving head rotates, the driving head is retracted in the direction of its own rotation axis by pressing the power output arm by the claw portion.

[0020] Furthermore, a pair of claws are provided on the power receiving part, an opening is formed between the pair of claws, and the processing box is also provided with an adjusting component that can adjust the position of the power receiving part so that the penetration direction of the opening faces the driving head when the processing box is installed in the imaging device.

[0021] Furthermore, the process cartridge is provided with an auxiliary disassembly member, and when the process cartridge is taken out from the imaging device, the auxiliary disassembly member is rotatable.

[0022] Furthermore, the driving head has a power output arm, and the power receiving part has a claw that can engage with the power output arm. When the processing box is installed in the image forming device and the power receiving part and the driving head are in contact but not coaxial, the power output arm can touch the claw and drive the power receiving part to rotate when the driving head rotates.

[0023] A processing box as described in claim 1, characterized in that the drive head has a power output arm, the power receiving part has a claw part that can engage with the output arm, and the claw part can move in a direction intersecting the rotation axis of the power receiving part.

[0024] After adopting the above scheme, when the power receiving part in the processing box interferes with the driving head in the imaging device, the power receiving part is driven to rotate by the driving head through the contact between the power receiving part and the driving head to overcome the interference state and achieve smooth installation, and the processing box is taken out by tilting to ensure smooth removal of the processing box. The technical problem that the power receiving part in the processing box cannot normally engage and disengage with the driving head in the imaging device in the prior art is solved.

[0044] The following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0045] Example 1

[0046] like Figure 1 The processing box of the present invention comprises a housing 1 having a developer containing portion, a handle 7 arranged at the rear end of the housing, a rotating component (not shown in the figure) arranged at the front end of the housing 1, the rotating component can be a photosensitive drum or a developing roller, and a driving component 10 arranged at the side end of the housing 1. The driving component 10 can receive the driving force in the imaging device and drive the above-mentioned rotating component to rotate. The processing box is also provided with a force receiving portion 2 arranged on the same side as the driving component 10.

[0047] like Figure 2 , which is a schematic diagram of the exploded structure of the processing box of the present invention on the side of the force-bearing part 2, a mounting part 5 is provided on the housing 1, one end of the first elastic member 3 abuts against the mounting part 5 and the other end abuts against the force-bearing part 2, and the cover plate 4 covers the force-bearing part 2 and the first elastic member 3 to prevent the force-bearing part 2 and the first elastic member 3 from coming out. The driving assembly 10 includes a power receiving part 11, which has a pair of claws 11a protruding along the rotation axis direction of the power receiving part.

[0048] like Figures 2 to 4As shown, the driving head 50 in the imaging device includes a pair of power output arms 50a. When the process cartridge is installed into the imaging device along the direction of arrow D in the figure, the power receiving portion 11 may have two states relative to the driving head 50. The first state is as follows: Figure 3 As shown, Figure 3 When the penetration direction X of the opening formed between a pair of claws 11a faces the drive head, and the power output arm 50a of the drive head 50 stays at a position that does not interfere with the claws 11a, the power receiving part 11 can directly pass through the drive head 50 and stay at a position coaxial with the drive head 50. When the machine door cover of the imaging device is closed, the imaging device drives the drive head 50 to rotate and engages with the power receiving part 11 to drive the power receiving part to rotate. In other words, this first state refers to the state in which the power receiving part 11 does not interfere with the drive head 50 in the imaging device during the installation of the processing cartridge. The second state is as follows Figure 4 As shown, in this state, the claw 11a of the power receiving part 11 will interfere with the driving head 50. At this time, when the machine door cover of the imaging device is closed, the machine door cover will press the force-bearing part 2 to keep the power receiving part 11 in contact with the driving head 50. When the imaging device drives the driving head 50 to rotate, the power output arm 50a of the driving head 50 will contact the claw 11a of the power receiving part 11 and make the power receiving part 11 rotate a certain angle. When the power receiving part 11 rotates to Figure 3 At the same time, the drive head 50 also rotates to the position Figure 3 When the power receiving part 11 is in the position where the driving head 50 is located, the power receiving part 11 will pass through the driving head 50 and stay at a position coaxial with the driving head 50 and then engage with the driving head 50 to receive the driving force. Optionally, the force-bearing part 2 can also receive the force of other positions in the imaging device except the machine door cover to keep the power receiving part 11 in contact with the driving head 50. In addition, the force-bearing part 2 can also be fixedly arranged on the shell 1, and the force-bearing part can receive the force of the elastic mechanism in the imaging device to keep the power receiving part 11 in contact with the driving head 50. In some imaging devices, the installation direction of the processing box installed in the imaging device is obliquely downward along the direction of gravity. In this state, the force-bearing part 2 may not be arranged on the processing box, and the gravity of the processing box can be used to achieve the contact between the power receiving part 11 and the driving head 50.

[0049] like Figure 5 and Figure 6As shown, the imaging device has a left side plate 101 and a right side plate 102, the processing box is supported between the left side plate 101 and the right side plate 102, and the housing 1 of the processing box can be tilted and moved between the left side plate 101 and the right side plate 102. When it is necessary to take out the processing box, the machine door cover in the imaging device is opened, and the handle 7 is grasped to pull the processing box outward. Since the power receiving part 11 and the drive head 50 are in a meshing state at this time, the processing box will use the junction point of the power receiving part 11 and the drive head 50 as a fulcrum, and the processing box will be smoothly taken out in a posture of rotating and tilting around the above-mentioned junction point.

[0050] Example 2

[0051] Next, the second embodiment of the process cartridge of the present invention is described. The difference between the second embodiment of the present invention and the first embodiment is that an adjustment mechanism is added to adjust the matching position of the power receiving portion 11 and the driving head 50. Figure 7 As shown, the driving component 10 in the second embodiment of the present invention is provided with an regulated portion 11b with an elliptical cross section on the power receiving portion 11, and a flange 15 is used to receive the driving force of the power receiving portion 11 and transmit it to the rotatable component in the processing box. An adjusting component positioning member 13 is also provided near the power receiving portion 11, and the adjusting component positioning member 13 can cooperate with the shell of the processing box to prevent it from rotating with the power receiving portion 11. The adjusting component 14 is installed in the adjusting component positioning member 13. In this embodiment, the adjusting component 14 is configured as a torsion spring, one end of which abuts against the adjusting component positioning member 13 and the other end abuts against the regulated portion 11b on the power receiving portion 11. At the same time, the power receiving portion 11 is configured to have a certain free gap relative to the flange 15 in the rotation direction. The adjusting component 14 can adjust the position of the power receiving portion 11 to the following by cooperating with the regulated portion 11b. Figure 3 The state shown can ensure that each time the process cartridge is installed into the imaging device along the installation direction D, the penetration direction of the opening formed between the pair of claws 11a is installed in a posture facing the drive head 50. This arrangement can reduce the probability of interference between the power receiving part 11 and the drive head 50 when the process cartridge is installed into the imaging device, and can also reduce the angle at which the power receiving part 11 needs to be rotated by the drive head 50, which can make the installation of the process cartridge smoother and increase the service life of the drive head.

[0052] Example 3

[0053] Next, embodiment 3 of the processing box of the present invention is described. The difference between embodiment 3 of the processing box of the present invention and embodiment 2 is that when the power receiving part of the processing box contacts the driving head in the imaging device, the power receiving part of the processing box also has a certain amount of activity, so that when the driving head rotates, the power output arm of the driving head can cut into between a pair of claws of the power receiving part.

[0054] Specifically, Figures 8 to 10 As shown, the claw portion 11a has a facing portion 11a2 facing the rotation axis of the power receiving portion 11 and a side surface 11a1 adjacent to the facing portion. The drive head 50 also includes a front end column portion 50b arranged at the lower end of the power output arm 50a. The pre-engagement state of the power receiving portion 11 and the drive head 50 in this embodiment is the same as that in Example 2, in which a part of the front end column portion 50b of the drive head 50b first cuts into the gap formed between the pair of claw portions 11a, and then the power output arm 50a will contact the side surface 11a1 of the claw portion 11a. In this embodiment, after the machine door cover of the printer is closed, the printer drives the drive head 50 to rotate. Since the power receiving part 11 is configured to have a certain amount of activity, the power output arm 50a of the drive head 50 will force the claw 11a of the power receiving part to move along the direction of arrow R in the figure. The direction of arrow R is the direction in which the claw 11a moves away from the axis in a direction perpendicular to the axis of the power receiving part. Then the power output arm 50a cuts into the open gap formed between a pair of claws 11a and contacts the facing part 11a2. As the drive head 50 rotates further, the power output arm 50a slides over the facing part 11a2, and the claw 11a moves along the S direction opposite to the R direction in the figure. Finally, the power receiving part 11 and the drive head 50 are as shown in FIG. Fig.10 The figure shows a normal meshing state, which refers to a state in which the power receiving part 11 is substantially coaxial with the driving head 50 .

[0055] Example 4

[0056] Next, a fourth embodiment of the process cartridge of the present invention will be described. Figures 11 to 13 As shown, the difference between this embodiment and the first embodiment is that when the power receiving part 11 and the driving head 50 are in a pre-engaged state and in contact, after the driving head 50 rotates, the power receiving part 11 is no longer driven to rotate by the driving head 50, but the driving head 50 is moved in the axial direction so that the power receiving part 11 is engaged with the driving head 50. Specifically, in this embodiment, Fig.11 As shown, the drive head 50 of the imaging device is configured to be elastically movable, and a second elastic component 51 is provided between the drive head 50 and the inner wall of the imaging device, and the second elastic component enables the drive head 50 to be telescopically movable in the direction of its own rotation axis. When the machine door cover of the printer is closed, the drive head 50 begins to rotate, and through the abutment between a side surface 11a1 of the claw portion 11a of the power receiving portion 11 and the power output arm 50a of the drive head 50, the drive head 50 can overcome the elastic force of the second elastic component 51 and move along the direction of the arrow M in the figure, and the M direction is the direction of the rotation axis of the drive head 50 and the M direction is the direction away from the claw portion 11a. As the drive head 50 retracts, the power output arm 50a will ultimately retract to a side surface 11a1 of the claw portion 11a (see Fig.11 ) disengagement position, which refers to a position in which the power output arm 50a does not contact the side 11a1 of the claw 11a in the axial direction of the power receiving part 11 and is no longer blocked by the side 11a1. At this position, the power output arm 50a of the drive head 50 will pass over the claw 11a from the top of the claw 11a. After the power output arm 50a passes over the claw 11a, the elastic force of the second elastic component 51 pushes the drive head 50 to extend axially toward the claw 11a. Finally, the power receiving part 11a and the drive head 50 enter the position as shown in the figure. Fig.13 The normal meshing state shown in FIG. 1 refers to a position where the power receiving part 11 and the driving head 50 are substantially coaxial.

[0057] Example 5

[0058] Next, a description will be given of Embodiment 5 of the process cartridge of the present invention. This embodiment differs from Embodiments 1 to 4 in that a part of the shape of the driving claw 11a of the driving force receiving member 11 is changed. Fig.14 As shown, in this embodiment, the facing portion 11a21 on the claw portion 11a of the power receiving portion 11 facing the axis of the power receiving portion 11 is set to an outwardly expanding conical shape. In other words, along an axial square perpendicular to the power receiving portion 11, the distance between the above-mentioned facing portion 11a21 and the axis of the power receiving portion 11 increases as the distance between the facing portion 11a21 and the flange 15 in the axial direction increases. Such a setting allows the power output arm 50a of the drive head 50 to be more flexibly cut into the gap formed between the pair of claw portions 11a, so that the power receiving portion 11 can be more flexibly and conveniently moved from the pre-engaged state to the engaged state with the drive head 50.

[0059] Example 6

[0060] Next, Embodiment 5 of the process cartridge of the present invention will be described. Fig.15 As shown, since a blocking component 60 is provided on the right side plate where the drive head 50 in some existing imaging devices is located, the blocking component 60 is rotatably provided on the right side plate 102, and a locking component (not shown in the figure) is also provided on the top plate (not shown in the figure) adjacent to the right side plate 102 to lock the blocking component 60 so that it cannot rotate. When the processing box is installed along the right side plate, it is necessary to first unlock the locking component provided on the right side plate 102 so that the blocking component 60 can resume rotation before continuing to be installed, and the locking component is a protruding structure installed in a groove in the top plate of the imaging device. Since the processing box in this embodiment needs to be tilted when taking out the imaging device, an auxiliary disassembly component is provided on the processing box. As shown in FIG. Fig.16As shown, in this embodiment, the housing of the process cartridge is provided with an auxiliary disassembly member mounting portion 1a, the auxiliary disassembly member 20 is provided with a through hole 20a, the through hole 20a is mounted on the auxiliary disassembly member mounting portion 1a and is rotatable, and the third elastic component 21 is provided between the auxiliary disassembly member 20 and the housing 1, one end of which abuts against the first end abutting portion 1c on the housing, and the other end abuts against the second end abutting portion 20c of the auxiliary disassembly member 20. The housing is also provided with a limiting portion 1b, which is used to contact with the limited portion 20b on the auxiliary disassembly member 20 to limit the position of the auxiliary disassembly member 20. When the process cartridge is initially installed in the imaging device, the auxiliary disassembly member 20 is limited to an initial position under the combined action of the third elastic member 21 and the limiting portion 1b on the housing. The initial position allows the locking member pusher 20d provided on the auxiliary disassembly member 20 to slide into the protruding structure in the groove provided in the top plate of the imaging device to unlock the locking member in the imaging device when the process cartridge is installed in the imaging device, so that the blocking member 60 resumes the rotation function, and the process cartridge pushes the blocking member 60 to rotate to complete the installation. When the process cartridge needs to be removed, the auxiliary disassembly member 20 can be removed as shown in the figure. Figure 6 The auxiliary disassembly member 20 overcomes the elastic force of the third elastic member 21 and rotates, so that the process cartridge will not be out of contact with the locking member in the imaging device even when the process cartridge is in a tilted state, so that the process cartridge can be removed smoothly. When the process cartridge is completely removed from the imaging device, the auxiliary disassembly member 20 is re-restricted to the initial position under the joint action of the elastic member 21 and the limiting portion 1b on the housing to facilitate the installation of the next one.

[0061] Example 7

[0062] Next, the embodiment 6 of the process cartridge of the present invention is described. Fig.17 and Fig.18As shown, the difference between this embodiment and embodiment 1 is that the force-bearing part in embodiment 1 is cancelled in this embodiment, and the power receiving part in this embodiment is arranged to be movable in a direction perpendicular to its own rotation axis. In this embodiment, a fourth elastic member 31 is arranged on the bracket 30 supporting the power receiving part 1101, one end of the fourth elastic member 31 abuts the bracket 31, and the other end abuts the power receiving part 1101, and a cover plate 32 covers the fourth elastic member 31 to prevent the fourth elastic member 31 from falling off. In order to realize the movement of the power receiving part 1101 in a direction perpendicular to its own axis, preferably, the power receiving part is arranged into a power receiving part 1101a, a power transmission part 1101c and an intermediate connecting part 1101b. A claw portion 1101a2 and a first sliding protrusion 1101a1 are provided on the power receiving part 1101a, a first guide groove 1101b1 and a second guide groove 1102b2 are provided on the intermediate connecting part 1101b, a second sliding protrusion 1101c and an axle pin mounting hole 1101c1 are provided on the power transmitting part 1101c, and an axle pin 1101d is installed in the axle pin mounting hole 1101c1. The axle pin 1101d can transmit the driving force of the power transmitting part 1101c to the flange 15. Among them, the power transmission part 1101c is installed in the flange 15 and fixed relative to the flange, the first sliding protrusion 1101a and the first guide groove 1101b1 cooperate and can slide relative to each other, the second guide groove 1101c2 and the second guide groove 1101b2 cooperate and can slide relative to each other, the extension directions of the first guide groove 1101b1 and the second guide groove 1102b2 intersect each other, preferably intersect each other at 90 degrees, such an arrangement can make the power receiving part 1101a move freely without directional restriction in a direction perpendicular to the rotation axis of the power receiving part 1101 relative to the power transmission part 1101c. In this embodiment, the fourth elastic member 31 is used to control the movement of the power receiving part 1101a. When the processing box is installed in the imaging device, when the power receiving part 1101a is in contact with the drive head 50 (see Figure 4 ) interferes, the power receiving part 1101a is pressed by the drive head 50 to overcome the elastic force of the fourth elastic member 31 and move. When the machine door cover is closed and the drive head 50 is rotated by the imaging device drive head, as the drive head 50 rotates, the fourth elastic member 31 will push the power receiving part 1101a in the direction close to the drive head 50 to achieve the engagement between the claw 1101a2 and the power output arm 50a of the drive head 50. In this embodiment, it is preferred to divide the power receiving part 1101 into three parts to achieve the effect of moving the power receiving part in a direction perpendicular to its own rotation axis. Optionally, the power receiving part can also be made into an integral part to move. After the power receiving part is set to move as a whole, it is only necessary to reserve enough space for the power receiving part to move in the hollow part of the flange.

[0063] In the above embodiments, the power receiving part is arranged to be immovable relative to the rotatable part in the axial direction of the rotatable part. In other words, in the first state, the claw of the power receiving part has a first distance relative to the rotatable part, and in the second state, the claw of the power receiving part has a second distance relative to the rotatable part. The above-mentioned first distance is set to be equal to the second distance. Compared with the prior art in which the power receiving part is arranged to be a retractable structure relative to the rotatable part, the stability of power transmission between the power receiving part and the rotatable part can be greatly increased.

[0064] The processing box provided by the present invention, when the power receiving part in the processing box interferes with the driving head in the imaging device, the power receiving part is driven to rotate by the driving head through the contact between the power receiving part and the driving head to overcome the interference state and achieve smooth installation, and the processing box is taken out by tilting to ensure smooth removal of the processing box. The technical problem that the power receiving part in the processing box cannot normally engage with and disengage from the driving head in the imaging device in the prior art is solved.
