Detailed Description
Example one
The present embodiment provides an image forming apparatus in which a developing unit and a photosensitive unit of a process cartridge mounted in a main body of the image forming apparatus are brought into contact with each other when the image forming apparatus operates, and are separated from each other when the image forming apparatus stops operating.
As shown in fig. 1 and 2, the process cartridge includes a photosensitive unit 100 and a developing unit 200 separated from each other. The photosensitive unit 100 includes a first casing 101 and a photosensitive member 102 rotatably provided in the first casing 101, and a first power receiving member 103 is further provided on one end of the first casing 101 in the rotational axis direction of the photosensitive member 102, the first power receiving member 103 being for engagement with a first rotating member 10 provided on an inner wall of the main body 1 of the image forming apparatus; the developing unit 200 includes a second casing 201 and a developing member 202 rotatably disposed in the second casing 201, a second power receiving member 204 is further disposed at one end of the second casing 201 in a rotational axis direction of the developing member 202, the second power receiving member 204 is configured to engage with a second rotary member 20 disposed on an inner wall of the main body 1 of the image forming apparatus, a guide portion is further disposed at an end of the second casing 201 in a length direction thereof, the guide portion is configured to guide the developing unit 200 to be mounted in the main body 1 of the image forming apparatus, and in the present embodiment, the guide portion preferably includes a first guide post 206 and a second guide post 207.
When the image forming apparatus is operated, a motor (not shown) provided in the main body 1 of the image forming apparatus drives the first rotating member 10 and the second rotating member 20 to rotate, thereby transmitting a rotational force to the photosensitive member 102 and the developing member 202, rotating the photosensitive member 102 and the developing member 202. In this process, an optical device (not shown) provided in the main body 1 of the image forming apparatus forms an electrostatic latent image on the surface of the rotating photosensitive member 102; the rubber layer of the surface of the developing member 202 is brought into contact with the photosensitive member 102, thereby transferring a developer (not shown) of the rubber layer surface onto the surface of the photosensitive member 102, developing the electrostatic latent image on the surface of the photosensitive member 102, forming a visible developer image, which is transferred onto a recording medium by a transfer roller provided in the main body 1 of the image forming apparatus and fixed by a fixing roller.
The guide rails are further provided on two opposite inner walls of the main body 1 of the image forming apparatus, and the embodiment will be described by taking the guide rail on one inner wall as an example, and the following description can be referred to for the guide rail on the other inner wall. As shown in fig. 2, a first guide rail 12 for mounting the photosensitive unit 100 and a second guide rail 13 for mounting the developing unit 200 are provided on an inner wall (not shown) of the main body 1 of the image forming apparatus. When it is necessary to mount the developing unit 200 (in the direction Y) and the photosensitive unit 100 (in the direction X) into the main body 1 of the image forming apparatus, the door 2 of the image forming apparatus is opened, the photosensitive unit 100 is mounted into the main body 1 of the image forming apparatus along the first guide rail 12, and the first rotary member 10 is extended to engage with the first power receiving member 103; after that, the developing unit 200 is mounted into the main body 1 of the image forming apparatus along the second guide rail 13, the first guide post 206 and the second guide post 207 provided on the end portion of the second casing 201 are supported on the second guide rail 13 and slide along the guide groove 131 of the second guide rail 13, the developing unit 200 is slid to the bottom of the second guide rail 13 along the second guide rail 13, and the first guide post 206 is locked by the locking device 14, so that the relative position of the developing unit 200 and the second guide rail 13 in the developing unit mounting direction is fixed. Also, the distance between the upper positioning surface 82 and the lower positioning surface 81 of the guide groove 131 of the second guide rail 13 is substantially the same as the diameter of the second guide post 207, and therefore, the upper positioning surface 82 and the lower positioning surface 81 can prevent the second guide post 207 located in the guide groove 131 from swinging around the first guide post 206, that is, prevent the developing unit 200 from swinging around the first guide post 206, and fix the developing unit 200 and the second guide rail 13 relative to each other in the circumferential direction of the developing unit 200. By the above fixing manner, the relative position of the developing unit 200 and the second guide rail 13 is fixed.
In the present embodiment, the second guide rail 13 is provided as a movable structure, and a pushing member is provided in the main body 1 of the image forming apparatus to push the second guide rail 13 to move, or to push the developing unit mounted on the second guide rail 13 to move, thereby bringing the developing member 202 of the developing unit 200 into contact with or away from the photosensitive member 102 of the photosensitive unit 100.
The present embodiment will be described below by taking as an example the case where the urging member urges the developing unit 200 to bring the developing member 202 of the developing unit 200 into and out of contact with the photosensitive member 102 of the photosensitive unit 100.
As shown in fig. 2, the first guide rail 12 is fixedly provided on the inner wall of the main body 1 of the image forming apparatus, and the second guide rail is movably connected to the inner wall of the main body 1 of the image forming apparatus. Preferably, the second guide rail 13 is divided into the fixed portion 7 and the movable portion 8, and the movable portion 8 is located downstream of the fixed portion 7 in the mounting direction of the developing unit 200. The fixed part 7 of the second guide rail 13 is fixedly connected with the inner wall of the main body 1 of the image forming device, and the movable part 8 is rotatably connected with the first support shaft 6 on the inner wall of the main body 1 of the image forming device; a first elastic member and a stopper portion 11 are further provided on the inner wall of the main body 1 of the image forming apparatus, the first elastic member applies an elastic force to the movable portion 8 of the second guide rail 13 to rotate the movable portion 8 of the second guide rail 13 around the first support shaft 6 to a position abutting against the stopper portion 11, at this time, the developing member 202 of the developing unit 200 mounted on the movable portion 8 of the second guide rail 13 is separated from the photosensitive member 102 of the photosensitive unit 100, the movable portion 8 is at the first position, and the developing unit 200 is at the separated position. Specifically, the first elastic member is a tension spring 9, one end of the tension spring 9 is fixed to the main body 1 of the image forming apparatus, and the other end is connected to the movable portion 8 of the second guide rail 13, so that the movable portion 8 of the second guide rail 13 rotates clockwise around the first support shaft 6 to the first position.
As shown in fig. 2 and 3, the urging member is a push rod 4, and the push rod 4 is extended in the P direction or contracted in the reverse direction of the P direction by receiving a driving force from a motor in the main body 1 of the image forming apparatus. Specifically, the upper surface of the push rod is provided with a rack 42, the rack 42 is engaged with a gear 5 provided in the main body 1 of the image forming apparatus, and the moving direction of the push rod 4 is controlled by controlling the rotating direction of the gear 5. Of course, other ways of controlling the movement of the push rod 4 are possible, such as: the push rod is controlled to extend and contract by controlling the rotation of the cam. One end of the push lever 4 in the projecting direction (P direction) is provided with a pushing portion 41, a pushed portion 203 is provided on the second housing 201 of the developing unit 200, and the pushed portion 203 of the developing unit 200 at the separated position is opposed to the pushing portion 41 of the push lever 4. When the image forming apparatus starts a developing operation, as shown in fig. 4, the image forming apparatus controls the push rod 4 to extend in the P direction, the pushing portion 41 of the push rod 4 abuts against the pushed portion 203 of the developing unit 200, and pushes the developing unit 200 to move to a position where the developing member 202 of the developing unit 200 contacts the photosensitive member 102 of the photosensitive unit 100, at which time the second power receiving member 204 of the developing unit 200 engages with the second rotating member 20 provided in the main body 1 of the image forming apparatus, and the movable portion 8 of the second guide rail 13 also rotates to the second position about the first support shaft 6 by the developing unit 200.
When the image forming apparatus stops operating, the image forming apparatus controls the push rod 4 to move in the reverse direction of the P direction, the pushing portion 41 of the push rod 4 has no effect on the pushed portion 203 of the developing unit 200, and the second guide rail 13 in the second position rotates clockwise about the first support shaft 6 to the first position by the tension spring 9, thereby separating the developing member 202 of the developing unit 200 from the photosensitive member 102 of the photosensitive unit 100.
In order to avoid that the urging force between the developing member 202 and the photosensitive member 102 which are in contact with each other is too large or too small due to an excessive or insufficient extension of the push rod 4 in the P direction by an error to affect the developing quality of the process cartridge, the contact manner between the urging portion 41 of the push rod 4 and the urged portion 203 of the second housing 201 may be set to be elastic contact. Preferably, the pushed portion 203 is elastically connected with the second housing 201, that is, a second elastic member is disposed between the pushed portion 203 and the second housing 201, when the pushed portion 203 is acted by the pushing portion 41 to move the pushed portion 203 relative to the second housing 201, the pushed portion 203 compresses the second elastic member, and when the force of the pushing portion 41 on the pushed portion 203 disappears, the second elastic member pushes the pushed portion 203 to move to the original position. In this embodiment, the pushed portion 203 is rotatably supported on the second support shaft 208 of the second housing 201, the second elastic member provided between the pushed portion 203 and the second housing 201 is a spring 209, one end of the spring 209 abuts against the pushed portion 203, and the other end abuts against the second housing 201. When the push rod 4 is extended too long or under in the P direction, a substantially stable urging force is maintained between the developing member 202 and the photosensitive member 102 by the cushioning action of the spring 209.
Of course, the pushing portion 41 of the push rod may be elastically connected to the push rod 4, or the pushing portion 41 of the push rod 4 or the pushed portion 203 of the second housing 201 may be made of an elastic material.
Further, the farthest distance between the first guide post 206 and the second guide post 207 provided at one end of the second housing 201 is substantially equal to the length of the guide groove 131 of the second guide rail 13. After the push lever 4 pushes the developing unit 200 to move to the contact position, as shown in fig. 4, the upper positioning surface 82 and the lower positioning surface 81 of the guide groove 131 in the movable portion 8 and the separation surface 71 of the fixed portion 7 opposite to the movable portion 8 simultaneously contact the second guide column 207, preventing the developing unit 200 in the contact position from moving in the taking-out direction in the guide groove 131, thereby further fixing the developing unit 200.
Example two
The present embodiment provides an image forming apparatus in which the developing unit 200 and the photosensitive unit 100 of a process cartridge mounted in the main body 1 of the image forming apparatus are brought into contact with each other when the image forming apparatus operates, and are separated from each other when the image forming apparatus stops operating.
In this embodiment, the structures of the guide rail and the push rod are substantially the same as those of the first embodiment, and the difference is that, as shown in fig. 5, a separation member 212 and a third elastic member are provided on the second housing 201, the separation member 212 can rotate around a third support shaft 213, and can rotate to a separation position (such as the position shown in fig. 5) under the action of the third elastic member, in this embodiment, the third elastic member is a torsion spring 211, one end of the torsion spring 211 abuts against the separation member 212, and the other end abuts against the second housing 201. In the process of mounting the developing unit 200 to the second guide rail 13, the spacer member 212 on the second casing 201 abuts against the pressed portion 104 of the first casing 101 of the photosensitive unit 100, so that there is a force between the second casing 201 and the first casing 101, the force acts on the movable portion 8 of the second guide rail 13 through the developing unit 200, the movable portion 8 rotates to the first position, so that the separated state is maintained between the developing member 202 and the photosensitive member 102, and the developing unit 200 is at the separated position.
When the image forming apparatus starts to operate, the push rod 4 is extended to apply a force to the pushed portion 203, so that the force between the developing unit 200 and the photosensitive unit 100 is increased, and the spacer member 212 is pressed between the developing unit 200 and the photosensitive unit 100 to rotate about the third support shaft 213, so that the developing unit 200 swings about the first support shaft 6 in the counterclockwise direction toward the photosensitive unit 100 until the developing member 202 of the developing unit 200 comes into contact with the photosensitive member 102 of the photosensitive unit 100, and the developing unit 200 is in the contact position.
When the image forming apparatus stops operating, as shown in fig. 6, the urging force of the urging member 4 to the urged portion 203 is reduced, so that the urging force between the developing unit 200 and the photosensitive unit 100 is also reduced, and the spacer member 212 is rotated in the counterclockwise direction about the third support shaft 213, urging the developing unit 200 to move away from the photosensitive unit 100, and separating the developing member 202 from the photosensitive member 102.
In this embodiment, the tension spring 9 is not provided to pull the second guide rail 13 to the first position, but the second guide rail 13 is automatically brought to the first position by the self weight of the second guide rail 13 without being affected by an external force, so that the developing unit 200 can be mounted on the second guide rail 13. Alternatively, as shown in fig. 7, a surface of the movable portion 8 of the second guide rail 13 located above the guide groove 131, which is opposite to the fixed portion 7, is a diagonal surface 83, and the diagonal surface 83 overlaps with a portion of the guide groove 131 located in the fixed portion 7 in the installation direction of the developing unit 200 by restricting the rotation angle of the movable portion 8 so that the movable portion 8 is not located at the first position (i.e., when the portion of the guide groove 131 located in the fixed portion 7 and the portion of the guide groove 131 located in the movable portion 8 do not overlap). Thus, in the process of mounting the developing unit 200 into the main body 1 of the image forming apparatus, if the movable portion 8 is not in the first position, the first guide post 206 provided at the end of the second housing 201 comes into contact with the ramp surface 83 and applies a force to the ramp surface 83 to rotate the movable portion 8 clockwise about the first support shaft 6 to the first position, so that the first guide post 206 enters the guide groove 131 of the movable portion 8. Of course, if the movable portion 8 is not in the first position before the second guiding post 207 enters the guiding groove 131 of the movable portion 8, the action of the second guiding post 207 on the inclined sliding surface 83 is similar to that of the first guiding post 206, and will not be described again here.
Of course, the spacer member 212 in the second embodiment may be in contact with the main body 1 of the image forming apparatus, or may be provided on the photosensitive unit 100 or the main body 1 of the image forming apparatus and in contact with the developing unit 200. The specific configuration of the main body 1 and the process cartridge of the image forming apparatus may be determined, and the present embodiment is not limited thereto.
Of course, in the above two embodiments, the push rod 4 may also directly act on the second guide rail 13, so that the second guide rail 13 drives the developing unit 200 to move. In addition, the present application may also fix the second guide rail 13, and the first guide rail may be movable with respect to the main body 1 of the image forming apparatus, thereby bringing the developing member 202 of the developing unit 200 into contact with and away from the photosensitive member 102 of the photosensitive unit 100 by moving the photosensitive unit 100. Alternatively, the movable portion 8 of the second guide rail 13 may also move the developing unit 200 in a translational manner, thereby bringing the developing member 202 of the developing unit 200 into contact with and away from the photosensitive member 102 of the photosensitive unit 100.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
