Abstract

A process cartridge, including a process cartridge housing, a photosensitive drum driving component, a driving force receiver, a flange component and a control mechanism. Opening parts are arranged on the driving force receiver and a retaining component is arranged on the process cartridge. When the control mechanism controls the driving force receiver to retract, the retaining component keeps the driving force receiver at a position noninterferential with a driving head of an image forming device. The driving force receiver and the flange component of the process cartridge are disengaged in a retracting state. In this state, the driving force receiving protrusion do not interfere with the front end column body of a machine driving head, and the process cartridge can be mounted and dismounted more smoothly.

Description

FIELD OF THE INVENTION [0002] The present disclosure relates to a process cartridge, photosensitive drum driving component.
BACKGROUND [0003] A process cartridge for an imaging device can be detachably installed within a main frame of the imaging device and, as a whole unit, comprises a photosensitive assembly and at least one processing means such as charging means, developing means, cleaning means, or the like. The process cartridge is detachably installed within the main frame of the imaging device for convenience of maintenance. An electrophotographic imaging device functions in the following manner: an electrostatic latent image is formed by selectively exposing the electrophotographic photosensitive assembly which is uniformly charged by a charger under light from the imaging device; the electrostatic latent image is developed with a developing means using a toner into a toner image; the toner image thus formed is transferred onto a recording medium by a transferring means to form an image on a recording material.
[0004] Generally, a driving force receiving device is arranged on the photosensitive component of the process cartridge and is engaged with a machine driving device in the image forming device so as to drive the photosensitive component to rotate and drive the whole process cartridge to work. However, the photosensitive component needs to be detachably mounted in the image forming device together with the process cartridge, therefore, when the process cartridge is taken out of the image forming device, it is required that the driving force receiving device is disengaged from the machine driving device so as to ensure that the process cartridge can be smoothly taken out of the image forming device; and when the process cartridge is mounted into the image forming device to carry out printing operation, it is required that the driving force receiving device is engaged with the machine driving device so as to ensure that the photosensitive component smoothly receives driving force.
[0005] In the prior art, many manufacturers adopt an extendable driving force receiving device, and a control mechanism for controlling extending and retracting of the driving force receiving device is arranged at one side of the process cartridge to realize engagement between the driving force receiving device and a machine driving device when the process cartridge works and disengagement between the driving force receiving device and the machine driving device when the process cartridge is dismounted. In a recent application of a patent with the publication number of CN204044516 by the applicant, a process cartridge is disclosed, a control mechanism is arranged at one side of the process cartridge and is configured as a pressing rod. When the process cartridge is mounted in the image forming device, the pressing rod is matched with a rail of the image forming device so as to control the extending and retracting of the driving force receiving device. In order not to change the using habit of a customer, a jacking block is arranged at a side end of the process cartridge, and can automatically jack up the process cartridge when a door of the image forming device is opened, so as to control the driving force receiving device to retract, thus facilitating dismounting of the process cartridge from the image forming device. However, the above mentioned structure has the following defects: the extendable stroke of the extendable driving force receiving device is usually restricted by the stroke of the control mechanism, and under the condition that the extendable stroke of the driving force receiving device is restricted, as the rotary stopping position of the driving force receiver of the driving force receiving device is not restricted, when the process cartridge is mounted or dismounted, if the driving force receiving protrusion of the driving force receiver is roughly coincided with or parallel to the mounting direction, the driving force receiving protrusion may interfere with a driving head in the machine driving device, and the process cartridge cannot be normally mounted and dismounted.Therefore, it is urgent to develop a new process cartridge to solve the problems above.
SUMMARY [0006] In order to solve the problems in the technical solution above, the present disclosure is implemented through the following technical solution. In general terms the present disclosure is directed to various embodiments of a process cartridge. In one embodiment, a process cartridge detachably mounted in an image forming device including a driving head includes a process cartridge housing, and a photosensitive drum driving component arranged at one side of the process cartridge housing. The photosensitive drum driving component includes a driving force receiver, which can be engaged with the driving head.
[0007] The photosensitive drum driving component also includes a flange component, wherein the driving force receiver can transfer driving force to the flange component. There is a control mechanism in the photosensitive drum driving component. The control mechanism receives external force of the image forming device to control the driving force receiver to extend and retract. When the control mechanism controls the driving force receiver to extend, the driving force receiver can transfer driving force to the flange component, and when the control mechanism controls the driving force receiver to retract, the driving force receiver can idle relative to the flange component.
[0008] Also, the photosensitive drum driving component includes a retaining component, which is arranged on the process cartridge and is configured to limit a rotary stopping position of the driving force receiver when the driving force receiver can idle relative to the flange component.
[0009] In one embodiment, a limiting part abutting against the retaining component is arranged on the driving force receiver, and the cross section of the limiting part is non circular. The limiting part may include a protrusion part and an abutment part, wherein the protrusion part and the abutment part extend for different distances from the axis of the driv4 ing force receiver along the radial direction of the driving force receiver. The distance which the abutment part extends from the axis of the driving force receiver along the radial direction of the driving force receiver is shorter than the distance which the protrusion part extends from the axis of the driving force receiver along the radial direction of the driving force receiver. When the driving force receiver can idle relative to the flange component, the retaining component abuts against the abutment part to limit the rotary stopping position of the driving force receiver.
[0010] In one embodiment, driving protrusions are arranged on the driving force receiver, driving force transmission protrusions are arranged on the flange component, and both the driving protrusions and the driving force transmission protrusions include guide inclined planes. A plurality of the driving protrusions and a plurality of the driving force transmission protrusions are provided. The driving force transmission protrusions extend along a direction parallel to the axial direction of the flange component.
[0011] In certain embodiments, a first driving block and a second driving block are detachably arranged on the driving force receiver. The first driving block and the driving force receiver can rotate relative to each other. The first driving block is configured to receive the force which Is from the control mechanism and is used for moving the driving force receiver in an extending-retracting direction. The second driving block and the driving force receiver are fixed in the rotation direction, and the second driving block is configured to transfer the driving force to the flange component. In one embodiment, the plurality of the driving force transmission protrusions are arranged on the second driving block. The retaining component may be a torsional spring in certain embodiments. When the driving force receiver rotates, the retaining component does not rotate synchronously with the driving force receiver.
[0012] In certain embodiments, the process cartridge may further include a holder. A locating column is arranged on the holder, and the retaining component is arranged on the locating column.
[0013] After adoption of the technical solution above, the driving force receiver and the flange component of the process cartridge in the present disclosure are disengaged in a retracting state, and the retaining component is arranged at the side end of the process cartridge and the limiting part is arranged on the driving force receiver. After the retaining component is matched with the limiting part and when the driving force receiver is in the retracting state, the driving force receiver, under the action of the retaining component, is always at a position non-interferential with a front end column body of a machine driving head. Thus, the process cartridge can be mounted and dismounted more smoothly.

[0040] As shown in Figs. 5A-5B, when the driving force receiver 21 of the process cartridge in the present disclosure is in an extending state under the action of the elastic force of the second elastic element 24, the driving protrusions 23b of the second driving block 23 are engaged with the driving force transmission protrusions 25b of the flange component 25, and at this moment, the driving force receiver 21 receives driving force and can drive the flange component 25 to rotate together .
[0041] As shown in Figs. 6A-6B, when the driving force receiver 21 of the process cartridge in the present disclosure is in a retracting state under the action of external force FI of the pressing rod 31, the driving protrusions 23b of the second driving block 23 are disengaged with the driving force transmission protrusions 25b of the flange component 25, and at this moment, the driving force receiver 21 can idle relative to the flange component 25, that is, the driving force receiver 21 can rotate freely around its rotating shaft without driving the flange component 25 to rotate.
[0042] In this embodiment, the second driving block 23 and the driving force receiver 21 are arranged separately, the second driving block 23 is configured as a middle component, and the driving force receiver 21can transfer a driving force to the flange component 25 by the middle component. It will be appreciated by those skilled in the art that the driving force receiver 21 and the second driving block 23 can also be configured as one component which is directly engaged with the flange component 25, to transfer the driving force to the flange component 25.
[0043] As shown in Fig. 1 and Fig. 7, a holder 18 is further arranged at a side end of the process cartridge and includes an opening 18a and a retaining component mounting part 18b.The driving force receiver 21 is configured to have at least one part positioned in the opening 18a, the retaining component mounting part 18b is configured as a positioning column, and the retaining component 19 is installed on the retaining component mounting part 18b.
[0044] As shown in Fig. 4 and Fig. 7, the driving force receiving protrusion 21a comprises jaw parts 21al and opening parts 21a2. The jaw parts 21al and the opening parts 21a2 are arranged alternately along the circumferential direction of the driving force receiver 21.The jaw parts 21al are configured to be engaged with a driving jaw 111 {refer to Fig. 9B) of the machine driving head 110 so as to receive driving force, and the opening parts 21a2 are configured to dodge a front end column body 112 (refer to Fig. 9B) of the machine driving head 110 and are formed between the two jaw parts 21al.
[0045] As shown in Fig. 7 and Fig. 10, the driving force receiver 21 includes the limiting part 21b, and the cross section of the driving force receiver 21 at the limiting part 21b is a non-circular cross section. The limiting part 21b comprises a protrusion part 21bl and an abutment part 21b2, and the protrusion part 21bl and the abutment part 21b2 extend different distances from the axis Y of the driving force receiver 21 along the radial direction of the driving force receiver 21.The abutment part 21b2 is configured as a plane abutting against one end 19a of the retaining component 19, and the protrusion part 21bl is configured as a protrusion which is protruded from the radial direction of the driving force receiver 21 and has a non-circular cross section. The retaining component 19 in this embodiment is configured as a torsional spring, therefore, under the condition that the driving force receiver 21 can idle, the retaining component 19, when getting contact with the protrusion part 21bl, can urge the driving force receiver 21 to rotate so as to ensure that the retaining component 19 abuts against the abutment part 21b2. As shown in Fig. 10, when one end 19a of the retaining component 19 abuts against the abutment part 21b2, the through direction of the opening parts 21a2 is parallel to the mounting direction X of the process cartridge. It is a preferred embodiment in this embodiment that the through direction of the opening parts 21a2 is parallel to the mounting direction X of the process cartridge. In order to prevent the driving force receiving protrusion 21a from interfering with the front end column body 112 of the machine driving head 110, after the retaining component 19 abuts against the abutment part 21b2, the angle between the through direction of the opening parts 21a2 and the mounting direction X of the process cartridge is not 90 degrees, and at this position, it can be ensured that under the condition that the retracting stroke of the driving force receiver 21 is restricted, the jaw parts 21al of the driving force receiver 21 do not interfere with the machine driving head 110 during mounting and dismounting. [0046] In this embodiment, the through direction of the opening parts 21a2 is an extension direction of the opening parts 21a2 between the jaw parts 21al, two jaw parts 21al are arranged symmetrically. It will be appreciated by those skilled in the art that the driving force receiver 21 can also include a plurality of jaw parts, and when the driving force receiver 21 includes a plurality of jaw parts, the opening parts in this embodiment refer to opening parts formed between the two jaw parts which are engaged with a driving jaw 111 of the machine driving head.
[0047] In this embodiment, the limiting part 21b can be arranged on the driving force receiver 21 in a way that the driving force receiver 21 includes the limiting part 21b or the limiting part 21b is mounted on the driving force receiver 21.
[0048] When the driving force receiver 21 is in a retracting state under the action of the external force FI of the pressing rod 31, the driving protrusions 23b of the second driving block 23 is disengaged from the driving force transmission protrusions 25b of the flange component 25, therefore, the driving force receiver 21 can idle relative to the flange component 25,and at this moment, the retaining component 19 applies a force to the limiting part 21b to enable the driving force receiver 21 to rotate, then the abutment part 21b2 rotates to abut against the retaining component 19.At this moment, the through direction of the opening parts 21a2 is roughly parallel to the mounting direction X of the process cartridge. Therefore, in this case, the driving force receiving protrusion 21a cannot interfere with the front end column body 112 of the machine driving head 110, and the process cartridge can be mounted and dismounted smoothly.
