Description

Processing box

Technical Field

The application relates to the field of printing technology, in particular to a processing box.

Background

An electrophotographic image forming apparatus is a device that forms an image on a recording material by an electrophotographic image forming process technique, for example: electrophotographic copiers, laser printers, electrophotographic printers, facsimile machines, word processors, and the like.

An electronic imaging device generally includes a main body (not shown), and a process cartridge detachably mounted in the main body. In the related art, as shown in fig. 1, a driving member 100 is provided in a main body of an electronic imaging device, and a power receiving member 101 is provided at one end in a longitudinal direction (X direction) of a process cartridge 1. In order to facilitate engagement of the driving member 100 and the power receiving member 101, the power receiving member 101 is generally provided in a structure (a gimbal structure) swingable in an arbitrary direction with respect to the longitudinal direction of the process cartridge 1, and the power receiving member 101 is swung toward the mounting direction of the process cartridge 1 by a torsion spring during mounting of the process cartridge 1 into the main body.

Specifically, as shown in fig. 2, the power receiving member 101 is connected to the hub 102, and the power receiving member 101 can oscillate in any direction with respect to the axis of the hub 102. The power receiving member 101 swings in the Y direction (mounting direction of the process cartridge 1) by the torsion spring 103. During mounting of the process cartridge 1 into the electronic imaging device, the driving member 100 abuts against the power receiving member 101, thereby swinging the power receiving member 101 in the reverse direction of the Y direction with respect to the axis of the hub 102. When the process cartridge 1 is moved to a position where the axis of the hub 102 is substantially coaxial with the axis of the driving member 100, the power receiving member 101 swings in the reverse direction of the Y direction with respect to the hub 102 to a position where the rotation axis of the power receiving member 101 is substantially coaxial with the rotation axis of the hub 102 by the driving member 100. At this time, the power receiving part 101 is engaged with the driving part 100, and the power receiving part 101 receives the rotational force from the driving part 100 and transmits the rotational force to the hub 102, and the hub 102 rotates other gears engaged therewith through gears provided on the circumferential surface thereof, thereby transmitting the rotational force to the other rotating parts.

However, since the power receiving member 101 can swing with respect to the hub 102, the power receiving member 101 is liable to shake during power transmission, resulting in insufficient stability of transmission of the rotational force, affecting the developing quality of the process cartridge 1. Moreover, the connection between the power receiving member 101 and the hub is relatively complex, and the assembly is not convenient.

Detailed Description

In the prior art, as shown in fig. 1, a first support shaft 21 and a second support shaft 22 are provided at both ends in the longitudinal direction (direction parallel to the X direction) of a first casing 2 of a process cartridge 1, and a first support hole 31 and a second support hole 32 are provided at both ends in the longitudinal direction (direction parallel to the X direction) of a second casing 3 of the process cartridge 1 corresponding to the first support shaft 21 and the second support shaft 22, respectively. The first housing 2 is rotatably supported on the second housing 3 by supporting the first support shaft 21 on the first support hole 31 and supporting the second support shaft 22 on the second support hole 32. Preferably, the developing unit 23 is provided on the first casing 2, the photosensitive unit 33 is provided on the second casing 3, and the developing unit 23 of the first casing 2 is separated from the photosensitive unit 33 of the second casing 3 by rotating the first casing 2 relative to the second casing 3 when the process cartridge 1 is in the non-operating state, so that the developing unit 23 is prevented from being deformed by being pressed by the photosensitive unit 33 for a long time.

Example 1

The present embodiment provides a process cartridge structure that enables a process cartridge to be mounted in a main body of an electronic image forming apparatus while a power receiving member of the process cartridge can be engaged with a driving member in the electronic image forming apparatus, the process cartridge is simple in structure, convenient to assemble, and stable in rotational force transmission.

The first housing 2 will be described below as an example.

As shown in fig. 3, the power receiving element 104 in this embodiment is provided integrally with the hub 1041, and the power receiving element 104 does not rotate relative to the hub 1041 during the power transmission, thereby stabilizing the transmission of the rotational force.

As shown in fig. 4, the power receiving member 104 is provided at one end of the first casing 2 in the X direction, a first pushed portion 24 is provided at one end of the first casing 2 opposite to the X direction, and a first pushing portion 34 is provided at one end of the second casing 3 opposite to the X direction, corresponding to the first pushed portion 24 of the first casing 2. Preferably, the first pushed portion 24 is a protrusion extending in the opposite direction of the X direction of the first housing 2, and one side of the first pushed portion 24 along the rotation direction of the first housing 2 relative to the second housing 3 is provided as a inclined sliding surface 25, and when the first housing 2 rotates by a set angle relative to the second housing 3, the inclined sliding surface 25 of the first pushed portion 24 abuts against the first pushing portion 34 of the second housing 3.

As shown in fig. 5, the first casing 2 is provided with a second pushed portion 26, and the main body of the electronic imaging device is provided with a second pushing portion 11 capable of abutting against the second pushed portion 26. When the process cartridge 1 is mounted in the main body of the electronic imaging device, the second pushing portion 11 is brought into abutment with the second pushed portion 26 of the first casing 2 by controlling the second pushing portion 11 to move in the Z direction, and the first casing 2 is pushed to rotate relative to the second casing 3.

After the second pushing portion 11 pushes the first casing 2 to rotate by a set angle with respect to the second casing 3, as shown in fig. 6, the inclined surface 25 of the first pushed portion 24 provided on the first casing 2 abuts against the first pushing portion 34 provided on the second casing 3. As the second pushing portion 11 continues to push the first casing 2, as shown in fig. 7, the first pushing portion 34 applies a force to the inclined slide surface 25 of the first pushed portion 24, so that the first casing 2 is moved in the X direction, and the power receiving member 104 provided at one end of the first casing 2 in the X direction is engaged with the driving member 100.

Of course, the first pushing portion 34 may be provided on the main body of the electronic imaging device, which is not limited in this embodiment.

Preferably, the diameters of the first and second support holes 31 and 32 are larger than the diameters of the first and second support shafts 21 and 22, respectively, so that the first housing 2 can move relative to the second housing 3 in a direction perpendicular to the length direction of the second housing 3. A third pushed portion (not shown) may be further provided on the first casing 2, and a third pushed portion (not shown) may be provided on the second casing 3. When the process cartridge 1 is taken out, a force is applied to the second casing 3 first, so that the second casing 3 moves in a direction perpendicular to the longitudinal direction of the second casing 3 with respect to the first casing 2, thereby bringing the third pushing portion into abutment with the third pushed portion and pushing the first casing 2 to move in the opposite direction of the X direction. Thereby disengaging the power receiving member 104 from the drive member 100. The action mode between the third pushing part and the third pushed part can refer to the action mode between the first pushing part and the first pushed part.

Of course, when the user takes out the process cartridge 1, the user may directly apply a force to the first casing 2 in the opposite direction of the X direction to move the first casing 2 in the opposite direction of the X direction, thereby disengaging the power receiving member 104 from the driving member 100.

Alternatively, as shown in fig. 4, an elastic member 27 is further provided at one end of the first housing 2 in the X direction, and the elastic member 27 applies an elastic force against the first housing 2 in the X direction. Preferably, the elastic member 27 is a spring, which is sleeved on the second support shaft 22, and one end of the spring abuts against the first housing 2, and the other end abuts against the second housing 3.

When the first housing 2 moves in the X direction, as shown in fig. 7, the spring is pressed, so that a force opposite to the X direction is applied to the first housing 2. When the second pushing portion 11 does not act on the first casing 2, the force applied to the first casing 2 by the spring moves the first casing 2 in the reverse direction of the X direction, thereby disengaging the power receiving member 101 from the driving member 100.

Further, since the power receiving member 101 of the process cartridge 1 is slowly moved in the radial direction of the driving member 100 with respect to the driving member 100 during engagement with the driving member 100, if the driving member 100 is in a rotated state when the power receiving member 101 is engaged with the driving member 100, the driving member 100 is brought into contact with the end of the driving pawl 1011 protruding in the X direction of the power receiving member 101 a plurality of times. If the driving pawl 1011 cannot be retracted, the driving member 100 may damage the driving pawl.

In order to avoid the above, in the present embodiment, the driving force receiving member is provided in a structure that is retractable with respect to the hub in the axial direction of the hub. Specifically, as shown in fig. 8, the power receiving part 105 is provided with a positioned portion 106 and a positioning catching groove 1051. Preferably, the positioned portion 106 has a cylindrical structure, and the positioning catching groove 1051 is provided on a circumferential surface of the opposite end of the power receiving member 105 in the X direction. The pin 107 passes through the power receiving member 105 in the radial direction of the power receiving member 105, with both ends thereof being located outside the power receiving member 105. Corresponding to the positioned portion 106 of the power receiving part 105 and both ends of the pin 107, a positioning portion 110 and a limit chute 111 are provided in the hub 109, and preferably, the positioning portion 110 is a cylindrical hole extending in the axial direction of the hub, and the diameter thereof is substantially the same as that of the positioned portion 106. The limit chute 111 is disposed in the positioning portion 110. An elastic member 108 is also provided between the power receiving part 105 and the hub 109, and preferably the elastic member 108 is a spring.

As shown in fig. 9, in the process of mounting the power receiving member 105 to the hub 109, the spring is first sleeved on the power receiving member 105, and then the power receiving member 105 is mounted in the positioning portion 110 of the hub 109, and the power receiving member 105 is slid in the X direction relative to the hub 109 by the engagement of the positioned portion 106 of the power receiving member 105 with the positioning portion 110 of the hub 109; both ends of the pin 107 enter into limit sliding grooves 111 of the hub 109, thereby limiting the rotation of the power receiving member 105 relative to the hub 109; one end of the spring abuts against the power receiving member 105 and the other end abuts against the hub 109, so that a force in the X direction is applied to the power receiving member 105, and the power receiving member 105 is projected in the X direction. After the positioning slot 1051 passes through the hub 109, the clip spring 112 is mounted to the positioning slot 1051 to position the power receiving member 105 to prevent the power receiving member 105 from being disengaged from the hub 109.

By providing the power receiving member in a structure that is retractable in the axial direction of the hub 109 with respect to the hub 109, the power receiving member can be retracted after the driving pawl of the power receiving member contacts the driving member, thereby avoiding the driving member and preventing the driving member from damaging the driving pawl.

Further, another structure may be employed to prevent the drive member from damaging the drive pawl of the power receiving member. Specifically, as shown in fig. 10, the second pushed portion 26 is rotatably supported on the first housing 2 through a rotation shaft 261, and an elastic member (not shown) is further provided between the first housing 2 and the second pushed portion 26, and applies a force to the second pushed portion 26 to rotate the second pushed portion 26 around the rotation shaft 261 in the opposite direction of the N direction to a set position, preferably, the elastic member is a spring. The first housing 2 is further provided with a first contact portion 29, and the second housing 3 is further provided with a second contact portion 39, and the first contact portion 29 and the second contact portion 39 are preferably protrusions having a certain elasticity.

When the second pushing portion 11 pushes the first housing 2 to rotate to a set angle in the M direction relative to the second housing 3, the second abutting portion 39 on the second housing 3 abuts against the first abutting portion 29 on the first housing 2 and blocks the rotation of the first housing 2; if the second pushing portion 11 continues to move in the Z direction, since the first housing 2 does not rotate, the second pushing portion 11 pushes the second pushed portion 26 to rotate in the N direction around the rotation shaft 261, the spring abutting against the second pushed portion 26 is pressed, and the pressing force is transmitted to the second abutting portion 39 through the first housing 2 and the first abutting portion 29. As the second pushing portion 11 moves along the Z direction, the spring abutting against the second pushed portion 26 is pressed more and more, so that the acting force between the first abutting portion 29 and the second abutting portion 39 is also increased, and the degree of deformation of the first abutting portion 29 and the second abutting portion 39 is also increased. When the first abutting portion 29 and the second abutting portion 39 are deformed to a certain extent, the first abutting portion 29 can directly pass over the second abutting portion 39, and the blocking effect of the second abutting portion 39 on the first housing 2 disappears. Under the action of the spring abutting against the second pushed portion 26, the first housing 2 is quickly moved to a predetermined position, so that the power receiving member of the second housing 2 is quickly engaged with the driving member, and thus, in the process of engagement of the power receiving member with the driving member, the number of times of contact between the driving pawl of the power receiving member and the driving member is reduced, so that the driving member is prevented from damaging the driving pawl of the power receiving member.

Example two

In this embodiment, the pushed portion is provided on the first casing or the second casing, and the pushing portion is provided in the main body of the electronic imaging device, and after the process cartridge is mounted in the electronic imaging device, the power receiving member is engaged with the driving member by controlling the pushing portion to move relative to the first casing or the second casing to push the first casing or the second casing to move in the longitudinal direction.

The present embodiment is also described taking the first housing 2 as an example. For ease of illustration, some of the structures in the drawings are not shown.

As shown in fig. 12 and 13, a fourth pushed portion 28 is provided on one side of the first housing 2 in the X direction, and a fourth pushed portion 12 is provided in the main body of the electronic imaging device, preferably, the fourth pushed portion 12 is a push rod structure, and one end thereof in the P direction is provided with a sloping slide surface 13. When the process cartridge 1 is mounted in the electronic imaging device, by controlling the fourth pushing portion 12 to move in the P direction, the inclined sliding surface 13 of the fourth pushing portion 12 is brought into abutment with the fourth pushed portion 28 of the first casing 2, and the second casing 2 is pushed to move in the X direction, so that the power receiving member 104 is engaged with the driving member 100.

Preferably, the fourth pushing part 12 and the second pushing part 11 are provided in a linkage structure, or the fourth pushing part 12 and the second pushing part 11 are directly provided as a whole. By setting the positions of the second pushing portion 11 and the fourth pushing portion 12, the fourth pushing portion 12 pushes the first housing 2 to move in the X direction to a position where the power receiving member 104 engages with the driving member 100 after the second pushing portion 11 pushes the first housing 2 to rotate by a certain angle with respect to the second housing 3. When it is necessary to take out the process cartridge 1, the reverse contraction of the fourth pushing portion 12 in the P direction is controlled so that the first casing 2 can be moved in the reverse direction of the X direction, disengaging the power receiving member 104 from the driving member 100.

Alternatively, the fourth pushing part 12 and the door cover of the electronic imaging device are arranged in a linkage structure, or the fourth pushing part 12 and the door cover of the electronic imaging device are directly arranged as a whole. When the process cartridge 1 is mounted in the main body of the electronic imaging device, the fourth pushing portion 12 protrudes in the P direction with the door cover closed, thereby pushing the first casing 2 to move in the X direction, and engaging the power receiving member 104 with the driving member 100. When the door is opened, the fourth pushing portion 12 is contracted in the reverse direction of the P direction, thereby enabling the first housing 2 to move in the reverse direction of the X direction, disengaging the power receiving member 104 from the driving member 100.

Preferably, as shown in fig. 3 and 12, an elastic member 27 is further provided at one end of the first housing 2 in the X direction, and the elastic member 27 applies an elastic force to the first housing 2 in the opposite direction of the X direction. Preferably, the elastic member 27 is a spring, which is sleeved on the second support shaft 22, and one end of the spring abuts against the first housing 2, and the other end abuts against the second housing 3.

In this embodiment, the structure of the power receiving component may refer to the first embodiment, and the description of this embodiment is omitted.

In the above two embodiments, when the power receiving part is provided on the second housing 3, the structure of the second housing 3 can be referred to as the structure of the first housing 2 as well. In addition, the shapes and positions of the pushed portion and the pushing portion may be determined according to the specific structure of the process cartridge, and the embodiment is not limited.

The first positioning protrusion a604 is provided on one side of the side plate a601a opposite in the aY direction and protrudes in the opposite direction of the aY direction; the second positioning protrusion a603 is provided at one side of the side plate a601a in the aY direction and protrudes in the aY direction, and the second positioning protrusion a603 is provided as a slant sliding surface toward one side in the aX direction. The first pushing part in the electronic imaging device is an inner wall a120 opposite to the first positioning protrusion a604, and the second pushing part is an extension plate a121 extending on an inner wall opposite to the second positioning protrusion a603 in the electronic imaging device. Preferably, the first positioning protrusion a604 is provided in a structure capable of elastically expanding and contracting in the aY direction or is directly made of an elastic material, so that the first positioning protrusion a604 is prevented from obstructing the movement of the process cartridge a60 to the second position.

When the process cartridge a60 is mounted in the electronic image forming apparatus, as shown in fig. 16, the inner wall a120 of the electronic image forming apparatus abuts against the first positioning protrusion a604 of the process cartridge a60, thereby pushing the whole of the process cartridge a60 to be offset in the aY direction by a distance so that the process cartridge is in the first position. At this time, the power receiving part a747 also moves a distance in the aY direction so as to avoid the driving part a100, and there is an overlap of the second positioning protrusion a603 and the protruding plate a121 in the aX direction. When the process cartridge a60 is moved to the point where the rotational axis of the power receiving member a747 approaches the rotational axis of the driving member a100, and there is an overlap of the power receiving member a747 and the driving member a100 in the aY direction, the inclined surface of the second positioning boss a603 of the process cartridge a60 abuts against the projecting plate a121 in the electrophotographic image forming apparatus, and as the process cartridge a60 continues to move in the aX direction, the projecting plate a121 pushes the second positioning boss a603 against the movement in the aY direction, i.e., pushes the process cartridge a60 against the movement in the aY direction, so that the power receiving member a747 is projected to engage with the driving member a100, at which time the process cartridge a60 is in the second position, as shown in fig. 17.

Of course, in the above embodiment, the first positioning protrusion a604 may not be provided with an elastic structure or made of an elastic material, and a groove capable of accommodating the first pushed portion may be preset on the inner wall of the electronic imaging device, and the opening of the groove faces the aY direction, so that when the second positioning protrusion a603 of the process cartridge is moved reversely in the aY direction by the action of the protruding plate a121, the first positioning protrusion a604 enters the groove, thereby preventing the first positioning protrusion a604 from obstructing the process cartridge from moving to the second position.

Of course, the first pushed portion and the second pushed portion may be disposed at other positions of the process cartridge, and the first pushed portion and the second pushed portion may be disposed at other positions of the electronic imaging device, specifically, may be determined according to the structures of the electronic imaging device and the process cartridge.

When it is necessary to take out the process cartridge from the electronic image forming apparatus, the process cartridge cannot be moved in the aY direction by the projecting plate a121, the power receiving member a747 is disengaged from the driving member a100, and the engaged power receiving member is engaged with the driving member, so that the process cartridge cannot be moved in the aX direction relative to the driving member, and is taken out from the electronic image forming apparatus.

In order to avoid the above, the present embodiment also provides a driving assembly capable of moving a distance in a direction perpendicular to the aY direction with respect to the process cartridge while maintaining the rotation axis of the power receiving member parallel to the aY direction. After the process cartridge is taken out of the electronic image forming apparatus by a distance in the reverse direction of the aX direction, the force of the protruding plate a121 on the process cartridge disappears, and the power receiving member can be moved in the aY direction together with the process cartridge, thereby disengaging the power receiving member from the driving member of the electronic image forming apparatus, and the process cartridge can be taken out of the electronic image forming apparatus.

Specifically, as shown in fig. 18, the drive assembly includes a power receiving member a757, a hub a740, and a connecting member a744 for connecting the power receiving member a757 and the hub a 740. The hub a740 is rotatably supported on the first housing a601 for receiving a rotational force and transmitting the rotational force to a rotating member within the process cartridge. A connection portion a742 is provided on a side of the hub a740 opposite to the aY direction, and a first chute a743 is provided on a side of the connection portion a742 opposite to the aY direction. Preferably, the length direction of the first sliding groove a743 is perpendicular to the rotation axis of the hub a740 (the rotation axis of the hub a740 is parallel to the aY direction). The first slide rail a745 engaged with the first slide groove a743 is provided on a side of the connection member a744 facing the connection portion a742, and the first slide groove a743 of the connection portion a742 is engaged with the first slide rail a745 of the connection member a744 to keep the rotation axis of the connection member a744 parallel to the rotation axis of the hub a740 and to slide in a direction perpendicular to the rotation axis of the hub a740 with respect to the connection portion a 742. A second slide groove a746 is provided at one side of the connection member a744 opposite to the aY direction, and a second slide rail a748 is provided at one end of the power receiving member a757 in the aY direction to be engaged with the second slide groove a746, preferably, the length direction of the second slide groove a746 is perpendicular to the rotation axis of the hub a740 and perpendicular to the length direction of the first slide groove a743. The second slide groove a746 of the connection member a744 is engaged with the second slide rail a748 of the power receiving member a757, so that the rotation axis of the power receiving member a757 is parallel to the rotation axis of the connection member a744, and the connection member a744 can be moved in a direction perpendicular to the rotation axis of the power receiving member a 757. That is, the rotation axis of the power receiving member a757 can be kept parallel to the rotation axis of the hub a740, and the power receiving member a757 can be moved relative to the hub a740 in a direction perpendicular to the rotation axis of the hub a 740.

When the process cartridge is moved in the reverse direction of the aX direction during the process of taking out the process cartridge from the electronic image forming apparatus, as shown in fig. 19, the power receiving member a757 is still kept engaged with the driving member, and the boss a740 is moved in the reverse direction of the aX direction together with the process cartridge, and after the process cartridge is moved by a set distance, the protruding plate a121 provided in the electronic image forming apparatus is out of contact with the second positioning boss a603 provided on the first casing a601, and the first positioning boss a604 pushes the process cartridge to move in the aY direction by the inner wall a120 of the electronic image forming apparatus, so that the power receiving member a757 is also moved in the aY direction to a position disengaged from the driving member a100, and the process cartridge is smoothly taken out from the electronic image forming apparatus.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
