Description

Technical Field

[0001] The utility model relates to the technical field of image formation, in particular to a processing box. Background Art

[0002] An image forming device is an imaging device that forms a visible image on a recording medium by an imaging principle, including an electrophotographic copier, an electrophotographic printer, an LED printer, etc. An image forming device generally includes a processing cartridge detachably mounted therein, and the processing cartridge, as a consumable part, often needs to be replaced.

[0003] In the prior art, a processing box usually consists of a developing box and a photosensitive drum box, which are connected in a specific manner to form a whole. The developing box is generally composed of a powder bin, a stirring frame, a powder feeding roller, a developing roller, a gear train and other components, thereby providing developer to the photosensitive drum box. The photosensitive drum box is generally composed of a waste powder bin, a cleaning blade, a charging component, a photosensitive drum and the like, wherein the photosensitive drum receives the developer provided by the developing roller to develop the electrostatic latent image.

[0004] Usually, a power receiving member is provided at one end of the processing box to receive the driving force of the main component of the image forming device. In the prior art, a processing box is disclosed, in which the end of the photosensitive drum adopts a universally rotatable power receiving member, so that it can be flexibly rotated during the process of meshing with the power output member of the main component to prevent jamming. However, this method of solving the jamming problem during the meshing process by universal rotation has disadvantages, that is, during the driving force transmission process, the power receiving member has too large a rotation freedom, which easily leads to unstable driving force transmission, and the structure of the universal rotation setting is particularly complex, which increases the production cost.

The force-bearing portion is configured to receive the force from the protrusion so as to move or rotate on a plane perpendicular to the first direction; when the force-bearing portion leaves the protrusion, the power receiving member extends out along the first direction to reset and engage with the power receiving member.

[0014] In some embodiments, the transmission part is configured to be non-rotatable, and receives the force from the force-bearing part through the inclined surface and moves along the first direction, thereby driving the power receiving member to contract toward the inside of the box body along the first direction.

[0106] Embodiment 1

[0107] The utility model provides a processing box 100, which is used for being detachably installed in a mounting portion 200 of a main component of an image forming device. The processing box 100 can be installed in the mounting portion 200 along a mounting direction.

[0108] In order to better illustrate the various components of the box body 110, the following is established: Figure 1 The axes of the three-dimensional rectangular coordinate system shown in the figure, the X-axis, the Y-axis, and the Z-axis are perpendicular to each other, the length direction of the box body 110 (i.e., the first direction) is set as the X-axis direction, the direction from the non-driving end 112 to the driving end 111 is the +X-axis direction, the direction in which the processing box is installed to the image forming device (i.e., the second direction) is set as the +Y-axis direction, and the direction perpendicular to the X-axis direction and the Y-axis direction is set as the Z-axis direction.

[0109] See also Figure 1 The side walls of the mounting portion 200 are provided with guide rails 202 respectively. The guide rails 202 are arranged along the mounting direction Y and are used to guide the installation of the processing box 100. A power output member 204, a tube control member 205 and a protrusion 203 are arranged on one side of the mounting portion 200. The power output member 204 is used to output driving force to the processing box 100, and the tube control member 205 can be used to guide the processing box 100 to be installed in the mounting portion 200. The protrusion 203 is arranged on the mounting portion 200 and is used to interact with the processing box 100 during installation, so that the power receiving member 120 can shrink in the axial direction to avoid the power output member 204 and prevent it from being stuck. Then the protrusion 203 leaves the processing box 100, and the power receiving member 120 extends in the axial direction to engage with the power output member 204.

[0110] See also Figure 2 , Figure 5The processing box 100 includes a box body 110, a photosensitive drum, a developing roller, a developing gear 124, a drum bracket 130 and a photosensitive drum driving assembly. The box body 110 has a driving end 111 and a non-driving end 112 opposite to each other in the length direction of the box body 110. The photosensitive drum is installed on the box body 110 along the length direction of the box body 110 and can rotate around its rotation axis. The developing roller is installed on the box body 110 along the length direction of the box body 110 and can rotate around its rotation axis. The developing gear 124 is fixedly arranged at the end of the developing roller. The drum bracket 130 is arranged at the driving end 111 of the box body 110, and has an arc-shaped outer surface 131 at the front end facing the installation direction.

[0111] See also Figure 2-5 The photosensitive drum driving assembly includes a power receiving member 120, a rotating transmission member 122, a photosensitive gear 123, a connecting member 125, a force-bearing portion 140, a transmission portion, a rotating reset member 172 and an axial shift reset member 171. In this embodiment, the transmission portion includes an axial shift member 154 and a bracket 180.

[0112] The power receiving member 120 is rotatably disposed on the drum bracket 130 and is coaxially connected to the photosensitive drum for receiving the driving force of the power output member 204 and transmitting the driving force to the photosensitive drum through the connecting member 125 and the rotating transmission member 122. Figure 5 , the power receiving member 120 is provided with an axial hole 121, and the connecting member 125 passes through the axial hole 121, and its two ends are clamped in the strip grooves on the inner wall of the rotating transmission member 122, so that the power receiving member 120 and the rotating transmission member 122 are connected in a transmission manner in the rotation direction. Since the axial hole 121 has a length in the axial direction, the power receiving member 120 can move axially relative to the connecting member 125 through the axial hole 121, that is, the power receiving member 120 can move relative to the connecting member 125 and the rotating transmission member 122 along the rotation axis. The rotating transmission member 122 is fixedly connected to the photosensitive drum to transmit driving force to the photosensitive drum. The photosensitive gear 123 is fixedly connected to the rotating transmission member 122 (specifically, it is integrally formed in this embodiment, and it can also be fixedly connected after being separately formed in other embodiments), and the photosensitive gear 123 is meshed with the developing gear 124, thereby transmitting driving force to the developing roller.

[0113] The force-bearing part 140 is a rod-shaped member, which is rotatably arranged at the end of the box body 110 around a rotation axis parallel to the first direction. One end of the force-bearing part 140 is a force-bearing end 141, and the other end is a pushing end 142. When the force-bearing end 141 receives the force of the protrusion 203, the force-bearing part 140 rotates on the YZ plane perpendicular to the X axis and acts on the pushed part 155 of the shaft moving part 154 through the pushing end 142. The rotation reset member 172 is used for rotation reset of the force-bearing part 140, which can be a torsion spring, which is sleeved on the force-bearing part 140.

[0114] The shaft shifting member 154 is arranged on the drum bracket 130, and can move relative to the drum bracket 130 in the axial direction (that is, in the direction of the rotation axis of the power receiving member 120), but cannot rotate relative to the drum bracket 130. The shaft shifting member 154 can be provided with a rib 157, and the drum bracket 130 is provided with a slide groove 134, and the rib 157 is arranged in the slide groove 134 and guided by the slide groove 134 so as to move in the axial direction. Specifically, the shaft shifting member 154 includes a bracket 180 and a pushed portion 155 fixed to each other. The power receiving member 120 is installed in the bracket 180, and can rotate relative to the bracket 180, but cannot move axially relative to the bracket 180. The pushed portion 155 is a rod-shaped member with one end connected to the bracket 180, and the other end of which is used to interact with the pushing end 142 of the force-bearing portion 140, so as to convert the rotational movement of the force-bearing portion 140 into the axial movement of the shaft shifting member 154. Specifically, the pushed part 155 and the pushing end 142 of the force-bearing part 140 are respectively provided with matching inclined surfaces (the inclined surfaces in this specification can be straight inclined surfaces or curved inclined surfaces), and through the interaction of the inclined surfaces, the rotational motion of the force-bearing part is converted into axial movement of the shaft moving member 154.

[0115] The axial displacement restoring member 171 is connected to the power receiving member 120, and is used to push the power receiving member 120 and the axial displacement member 154 to extend and reset along the axial direction. The axial displacement member 154 can further push the force receiving part 140 to rotate and reset through the inclined surface 158 of the pushed part 155, or the force receiving part 140 is further provided with a restoring member to reset it. The axial displacement restoring member 171 can be a spring.

[0116] The installation process of the process cartridge 100 of this embodiment is as follows:

[0117] The process box 100 moves along the guide rail 202 (see Figure 6 ) until it contacts the protrusion 203 (see Figure 7), the force-bearing end 141 of the force-bearing part 140 is pushed to the left by the protrusion 203, so that the pushing end 142 of the force-bearing part 140 rotates to the right and acts on the inclined surface 158 of the pushed part 155 of the axial displacement part 154 through the inclined surface, so that the axial displacement part 154 moves axially and pushes the power receiving part 120 to shrink toward the inside of the box body 110 along the axial direction of the rotation axis. The power receiving part 120 shrinks and can avoid the power output part 204 that is about to hit, preventing the two from colliding or getting stuck. The processing box 100 continues to move along the guide rail 202 to the final position, and the power receiving member 120 moves with the processing box 100 to a position where the axis of the power output member 204 coincides. The two are relative but not engaged. At this time, since the protrusion 203 leaves the force-bearing part 140, the force on the force-bearing part 140 disappears, and it rotates and resets under the action of the rotation reset member 172, and the force applied to the shaft shifting member 154 also disappears. Under the action of the shaft shifting reset member 171, the power receiving member 120 and the shaft shifting member 154 extend axially and reset to the initial position, and the power receiving member 120 is engaged with the power output member 204 (see Figure 8 The shaft moving member 154 pushes the force receiving portion 140 to rotate and reset through the inclined surface 158 of the pushed portion 155 .

[0118] The control method of the utility model is to control the power receiving member 120 to first shrink axially during the installation of the processing box 100, and then extend axially to engage with the power output member 204 after the processing box 100 is installed in place. This can prevent the power receiving member 120 and the power output member 204 from colliding or getting stuck during the installation process, resulting in a situation where they cannot engage, thereby improving the installation smoothness of the processing box 100. At the same time, the power receiving member 120 does not need to be set as a universal rotation, and its structure is simple and the driving force transmission is stable.

[0119] See also Fig. 9 In the present embodiment, the drum bracket 130 has an arc-shaped outer surface 131 at the front end facing the installation direction, and the shortest distance between the arc-shaped outer surface 131 and the rotation axis of the power receiving member 120 is L2 (that is, the radius of the arc-shaped outer surface 131), and the shortest distance between the pushing end 142 of the force-bearing part 140 and the rotation axis of the power receiving member 120 is L1. When the force-bearing part 140 is in the initial position and when the force-bearing part 140 moves under the force of the protrusion 203, that is, no matter where the force-bearing part 140 is, L1≥L2 is satisfied. In the present embodiment, specifically, L1=L2.

[0120] Since the location of the pushing end 142, that is, the force-bearing part 140 and the axial displacement part 154, is set far away from the power receiving part 120 and the position of the tube control part 205 of the installation part 200, the force-bearing part 140 can be prevented from interfering with the tube control part 205 during movement, so that the processing box 100 can be smoothly installed and used, and the influence of the force-bearing part 140 on the power receiving part 120 when transmitting the driving force can be reduced, which can better ensure the stable transmission of the driving force.

[0121] This embodiment also provides a variant implementation:

[0122] See also Fig.10 In this modified embodiment, L1>L2, so that the force-bearing portion 140 can be further away from the tube control unit 205 and the power receiving unit 120, preventing the force-bearing portion 140 from interfering with the tube control unit 205 during movement, so that the processing box 100 can be smoothly installed and used, and the influence of the force-bearing portion 140 on the power receiving unit 120 when transmitting the driving force can be reduced, which can better ensure the stable transmission of the driving force.

[0123] In other embodiments, the force-bearing portion 140 may not satisfy L1 ≥ L2.

[0124] Embodiment 2

[0125] This embodiment is substantially the same as the embodiment, and the main difference is that the movement of the force-bearing part 140 is not rotation but linear movement, specifically, linear movement on the YZ plane perpendicular to the X axis. In addition, in this embodiment, the shaft moving member 154 and the bracket 180 are integrally arranged, that is, the bracket 180 is not separately arranged, and the bracket 180 is directly formed on the shaft moving member 154.

[0126] See also Figure 11-15 The photosensitive drum driving assembly of this embodiment includes a power receiving member 120, a rotating transmission member 122, a photosensitive gear 123, a connecting member 125, a limiting portion 132, a force receiving portion 140, a transmission member, an axial shifting and restoring member 171, and a moving and restoring member 190, wherein the transmission member includes an axial shifting member 154. The arrangement of the rotating transmission member 122, the photosensitive gear 123, and the connecting member 125 is the same as that of the first embodiment, and will not be repeated.

[0127] See also Fig.12 The limiting portion 132 is a sheet-like covering member fixed to the end of the box body 110 and / or the drum bracket 130, which at least partially covers the force-bearing portion 140 to prevent the force-bearing portion 140 from axially escaping from the processing box 100.

[0128] The force-bearing part 140 is a rod-shaped component, which is arranged at the end of the box body 110 and can move linearly relative to the box body 110. The direction of the linear movement can be the direction of approaching or moving away from the power receiving part 120. One end of the force-bearing part 140 is a force-bearing end 141, and the other end is a pushing end 142. The pushing end 142 is provided with an inclined surface. When the force-bearing end 141 receives the force of the protrusion 203, the force-bearing part 140 moves along a straight line and acts on the pushed part 155 of the axial displacement part 154 through the inclined surface of the pushing end 142.

[0129] The movable reset member 190 is used to push the force receiving portion 140 to return to the initial position when the protrusion 203 leaves the force receiving portion 140. The movable reset member 190 can be a spring, one end of which abuts against the force receiving portion 140 and the other end abuts against the box body 110.

[0130] The shaft shifting member 154 is arranged on the drum bracket 130, and can move relative to the drum bracket 130 in the axial direction (that is, in the direction of the rotation axis of the power receiving member 120), but cannot rotate relative to the drum bracket 130. Specifically, the shaft shifting member 154 includes a bracket 180 and a pushed portion 155 fixed to each other. In this embodiment, the bracket 180 and the pushed portion 155 are integrally formed, and in other embodiments, they can also be separately formed and fixedly connected. The power receiving member 120 is installed in the bracket 180, and can rotate relative to the bracket 180, but cannot move axially relative to the bracket 180. A stopper 181 can be used to prevent the power receiving member 120 from moving axially relative to the bracket 180. The pushed portion 155 is a rod-shaped member connected to the bracket 180 at one end, and the other end is used to interact with the pushing end 142 of the force-bearing portion 140, so as to convert the linear motion of the force-bearing portion 140 into the axial movement of the shaft shifting member 154. Specifically, the pushed part 155 and the pushing end 142 of the force-bearing part 140 are respectively provided with matching inclined surfaces. Through the interaction of the inclined surfaces, the rotational movement of the force-bearing part 140 is converted into axial movement of the axial displacement member 154. In order to achieve a movement different from that of Example 1, the inclination direction of the inclined surface of this embodiment is different from that of Example 1.

[0131] The shaft shift reset member 171 is connected to the power receiving member 120 and is used to push the power receiving member 120 and the shaft shift member 154 to extend and reset along the axial direction. The shaft shift reset member 171 can be a spring.

[0132] The installation process of the process cartridge 100 of this embodiment is as follows:

[0133] The processing box 100 moves along the guide rail 202 until it abuts against the protrusion 203. The force-bearing end 141 of the force-bearing part 140 is pushed by the protrusion 203, causing the force-bearing part 140 to move downward in a straight line, and its pushing end 142 moves accordingly and acts downward on the inclined surface 158 of the pushed part 155 of the axial displacement member 154 through the inclined surface, causing the axial displacement member 154 to move axially and push the power receiving member 120 to retract toward the inside of the box body 110 along the axial direction of the rotation axis. The power receiving member 120 retracts and can avoid the power output member 204 that is about to collide with it, thereby preventing the two from colliding or getting stuck. The processing box 100 continues to move along the guide rail 202 to the final position, and the power receiving member 120 moves with the processing box 100 to a position coincident with the axis of the power output member 204. The two are relative but not engaged. At this time, since the protrusion 203 leaves the force-bearing part 140, the force acting on the force-bearing part 140 disappears. Under the action of the moving reset member 190, the force-bearing part 140 moves upward in a straight line and resets. The force applied to the axial shifting member 154 also disappears. Under the action of the axial shifting reset member 171, the power receiving member 120 and the axial shifting member 154 extend axially and reset to the initial position, and the power receiving member 120 is engaged with the power output member 204.

[0134] See also Fig.16 In the present embodiment, the drum bracket 130 has an arc-shaped outer surface 131 at the front end facing the installation direction, and the shortest distance between the arc-shaped outer surface 131 and the rotation axis of the power receiving member 120 is L2 (that is, the radius of the arc-shaped outer surface 131), and the shortest distance between the pushing end 142 of the force-bearing part 140 and the rotation axis of the power receiving member 120 is L1. When the force-bearing part 140 is in the initial position and after the force-bearing part 140 moves under the force of the protrusion 203, that is, no matter where the force-bearing part 140 is, L1≥L2 is satisfied.

[0135] Since the location of the pushing end 142, that is, the force-bearing part 140 and the axial displacement part 154, is set far away from the power receiving part 120 and the position of the tube control part 205 of the installation part 200, the force-bearing part 140 can be prevented from interfering with the tube control part 205 during movement, so that the processing box 100 can be smoothly installed and used, and the influence of the force-bearing part 140 on the power receiving part 120 when transmitting the driving force can be reduced, which can better ensure the stable transmission of the driving force.

[0136] Embodiment 3

[0137] This embodiment is basically the same as the second embodiment, except that: the force bearing portion 140 (see Figure 20-21 ) and the shaft shifting member 154 (see Fig.18 ) is slightly different in appearance and structure from that of the second embodiment, but its working principle is the same as that of the second embodiment, which will not be described in detail here.

[0138] Specifically, Fig. 20 As shown, in this embodiment, a mounting groove 170b is provided on the driving end 111 of the box body 110, and the mounting groove 170b extends to the drum bracket 130. The force-bearing part 140 is movably mounted in the mounting groove 170b.

[0139] See also Fig.17 A guide post 170a is provided on the processing box. When the processing box is installed in the installation portion, the guide post 170a can move in the guide rail 202, so that the processing box can be correctly installed in the image forming device.

[0140] The end of the force-bearing part 140 extending out of the box body 110 has a roughly conical structure and has two fourth inclined surfaces 161b. When the processing box is installed in the mounting part of the image forming device, the protrusion 203 will abut against the force-bearing part 140, and the fifth inclined surface 220a on the protrusion 203 will abut against the fourth inclined surface 161b. The protrusion 203 pushes the force-bearing part 140 to move in the mounting groove 170b, and the force-bearing part 140 can push the power receiving part 120 to extend and retract.

[0141] See also Figure 22-23 The image forming device is also provided with a swing rod 230, which can be pushed to swing in the image forming device, and the swing rod 230 can shield the power output member 204 provided in the image forming device, so as to prevent the power output member 204 from being damaged or falling into impurities when not in use, thereby affecting the transmission. Specifically, a shielding cover 231 is provided at the end of the swing rod 230, and the other end of the swing rod 230 is movably connected to the inner wall of the mounting portion, so that the swing rod 230 can swing freely. When the swing rod 230 swings, the shielding cover 231 can rotate to the position of the power output member 204 to shield the power output member 204.

[0142] See also Fig.19 In this embodiment, the box body 110 is further provided with a protrusion 153a. When the process box is installed in the image forming device, the protrusion 153a can push the swing rod 230 to expose the power output member 204 in the image forming device. The power output member 204 can be connected to the power receiving member 120 to achieve drive transmission. Specifically, the protrusion 153a is arranged at the driving end of the box body 110. Preferably, as shown in FIG. Fig.19 As shown, the protrusion 153a is disposed on the drum bracket 130, the protrusion 153a is an arc-shaped protrusion and is disposed around the power receiving member 120, and the arc-shaped protrusion 153a and the power receiving member 120 are disposed concentrically; as shown Fig.24 As shown, when the processing box is installed in the image forming device, the protrusion 153a can push the swing rod 230 to swing, so that the power receiving member 120 in the image forming device is exposed for transmission connection with the power receiving member 120.

[0143] Embodiment 4

[0144] This embodiment is substantially the same as Embodiments 1 and 2, and the main difference lies in that: in Embodiments 1 and 2, the transmission part (including the axial shifting member 154, or including the axial shifting member 154 and the bracket 180) is configured to be non-rotatable and can only move along the first direction, in this embodiment, at least part of the transmission part (specifically the rotating part 150) can rotate, specifically, the transmission part includes the rotating part 150 and the axial pushing part 160, the axial pushing part 160 is configured to be non-rotatable, and the rotating part 150 is used to receive the force from the force-bearing part 140 and rotate, thereby acting with the axial pushing part 160, so that the rotation of the rotating part 150 is converted into a contraction movement of the power receiving part along the first direction.

[0145] See also Figure 25-28 The photosensitive drum driving assembly includes a power receiving member 120, a rotating transmission member 122, a photosensitive gear 123, a connecting member 125, a force-bearing portion 140, a rotational reset member 172, a rotating component 150, a transmission portion, a second rotational reset member 170 and an axial shift reset member 171, wherein the transmission portion includes a rotating component 150 and an axial push portion 160.

[0146] The power receiving member 120 is rotatably disposed on the drum bracket 130 and is coaxially connected to the photosensitive drum for receiving the driving force of the power output member 204 and transmitting the driving force to the photosensitive drum through the connecting member 125 and the rotating transmission member 122. Fig. 27 and Fig.28 , the power receiving member 120 is provided with an axial hole 121, and the connecting member 125 passes through the axial hole 121, and its two ends are clamped in the inner wall of the rotating transmission member 122, so that the power receiving member 120 and the rotating transmission member 122 are connected in a transmission manner in the rotation direction. Since the axial hole 121 has a length in the axial direction, the power receiving member 120 can move axially relative to the connecting member 125 through the axial hole 121, that is, the power receiving member 120 can move relative to the connecting member 125 and the rotating transmission member 122 along the rotation axis. The rotating transmission member 122 is fixedly connected to the photosensitive drum to transmit driving force to the photosensitive drum. The photosensitive gear 123 is fixedly connected to the rotating transmission member 122 (specifically, it is integrally formed in this embodiment, and it can also be fixedly connected after being separately formed in other embodiments), and the photosensitive gear 123 is meshed with the developing gear 124, thereby transmitting driving force to the developing roller.

[0147] The force-bearing part 140 is a rod-shaped member, which is rotatably arranged at the end of the box body 110. One end of the force-bearing part 140 is a force-bearing end 141, and the other end is a pushing end 142. When the force-bearing end 141 receives the force of the protrusion 203, the force-bearing part 140 rotates and acts on the pushed part 152 of the rotating component 150 through the pushing end 142. The rotation reset member 172 is used for rotation reset of the force-bearing part 140, which can be a torsion spring, which is sleeved on the force-bearing part 140.

[0148] The rotating component 150 is arranged on the drum bracket 130, and it can rotate around the rotation axis of the power receiving member 120 relative to the drum bracket 130, and can also move axially along the rotation axis relative to the drum bracket 130. The rotating component 150 includes a circular ring portion 151, a pushed portion 152 and an action portion 153 fixed to each other. The circular ring portion 151 is rotatably arranged on the drum bracket 130 and is coaxial with the power receiving member 120. The action portion 153 is an axial protrusion 203 formed on the circular ring portion 151. The pushed portion 152 is a rod-shaped member with one end connected to the circular ring portion 151, and the other end is used to interact with the pushing end 142 of the force-bearing portion 140.

[0149] The shaft pushing portion 160 is a protrusion fixedly arranged on the drum bracket 130, which is used to force the action portion 153 of the rotating member 150 to move axially. The drum bracket 130 can also be provided with a limiting portion 132 to prevent the rotating member 150 from escaping from the processing box 100 when moving axially.

[0150] The second rotation reset member 170 is sleeved on the power receiving member 120 and connected to the rotating member 150, and is used for rotation reset of the rotating member 150. The second rotation reset member 170 can be a torsion spring. One end of the second rotation reset member 170 is inserted into the bracket 180, and the other end is in contact with the rotating member 150.

[0151] The axial displacement restoring member 171 is connected to the power receiving member 120 and is used to push the power receiving member 120 to extend and restore along the axial direction. The axial displacement restoring member 171 can be a spring.

[0152] The photosensitive drum drive assembly may further include a bracket 180, the power receiving member 120 is rotatably mounted on the bracket 180, the bracket 180 is disposed in the annular portion 151, and the bracket 180 and the annular portion 151 can move synchronously in the axial direction, so that when the rotating component 150 moves in the axial direction, the power receiving member 120 can be driven to move synchronously in the axial direction through the bracket 180. When the power receiving member 120 is reset in the axial direction under the action of the axial displacement reset member 171, the power receiving member 120 can also be driven to reset in the axial direction through the bracket 180.

[0153] The installation process of the process cartridge 100 of this embodiment is as follows:

[0154] The process box 100 moves along the guide rail 202 (see Fig.29 ) until it contacts the protrusion 203 (see Fig.30 ), the force-bearing end 141 of the force-bearing part 140 is pushed to the left by the protrusion 203, and its pushing end 142 rotates to the right accordingly and acts on the pushed part 152 of the rotating part 150, the rotating part 150 rotates clockwise, and the acting part 153 rotates accordingly to a position abutting against the axial pushing part 160. Under the forced push of the axial pushing part 160, the rotational motion of the rotating part 150 is converted into axial motion, pushing the bracket 180 to shrink axially toward the inside of the box body 110, thereby driving the power receiving part 120 to shrink axially toward the inside of the box body 110. The contraction of the power receiving part 120 can avoid the power output part 204 that is about to hit, to prevent the two from colliding or getting stuck. The processing box 100 continues to move along the guide rail 202 to the final position, and the power receiving member 120 moves with the processing box 100 to a position that coincides with the axis of the power output member 204. The two are relative but not engaged. At this time, since the protrusion 203 leaves the force-bearing portion 140, the force applied to the force-bearing portion 140 disappears, and it is rotated and reset under the action of the rotation reset member 172, and the force applied to the rotating member 150 also disappears. Under the action of the second rotation reset member 170, the rotating member 150 is rotated and reset to the initial position, and the action portion 153 rotates and leaves the shaft push portion 160, and the axial thrust applied to the action portion 153 disappears. Under the action of the shaft displacement reset member 171, the power receiving member 120 is extended and reset in the axial direction, thereby engaging with the power output member 204 (see Fig.31 ).

[0155] The control method of the utility model is to control the power receiving member 120 to first shrink axially during the installation of the processing box 100, and then extend axially to engage with the power output member 204 after the processing box 100 is installed in place. This can prevent the power receiving member 120 and the power output member 204 from colliding or getting stuck during the installation process, resulting in a situation where they cannot engage, thereby improving the installation smoothness of the processing box 100. At the same time, the power receiving member 120 does not need to be set as a universal rotation, and its structure is simple and the driving force transmission is stable.

[0156] See also Fig.32 In the present embodiment, the drum bracket 130 has an arc-shaped outer surface 131 at the front end facing the installation direction, and the shortest distance between the arc-shaped outer surface 131 and the rotation axis of the power receiving member 120 is L2 (that is, the radius of the arc-shaped outer surface 131), and the shortest distance between the pushing end 142 of the force-bearing part 140 and the rotation axis of the power receiving member 120 is L1. When the force-bearing part 140 is in the initial position and when the force-bearing part 140 moves under the force of the protrusion 203, that is, no matter where the force-bearing part 140 is, L1≥L2 is satisfied. In the present embodiment, specifically, L1=L2.

[0157] Since the location of the pushing end 142, that is, the location where the force is applied to the force-bearing portion 140 and the rotating component 150, is arranged away from the power receiving member 120 and also away from the location of the tube control unit 205 of the mounting portion 200, the force-bearing portion 140 can be prevented from interfering with the tube control unit 205 during movement, so that the processing box 100 can be smoothly installed and used, and the influence of the force-bearing portion 140 on the power receiving member 120 when transmitting the driving force can be reduced, so as to better ensure the stable transmission of the driving force.

[0158] This embodiment also provides a variant implementation:

[0159] See also Fig.33 In this modified embodiment, L1>L2, so that the force-bearing portion 140 can be further away from the tube control unit 205 and the power receiving unit 120, preventing the force-bearing portion 140 from interfering with the tube control unit 205 during movement, so that the processing box 100 can be smoothly installed and used, and the influence of the force-bearing portion 140 on the power receiving unit 120 when transmitting the driving force can be reduced, which can better ensure the stable transmission of the driving force.

[0160] Embodiment 5

[0161] This embodiment is substantially the same as the fourth embodiment, and the main difference is that: in the fourth embodiment, the shaft pusher 160 is fixedly arranged on the drum bracket 130, and in this embodiment, the shaft pusher 160 is arranged to be able to move along the first direction relative to the drum bracket 130. In the fourth embodiment, the rotating component 150 is able to move along the first direction, and in this embodiment, the rotating component 150 is arranged not to be able to move along the first direction. When the rotating component 150 rotates, the shaft pusher 160 interacts with the rotating component 150 through the inclined surface, so that the rotational motion of the rotating component 150 is converted into the movement of the shaft pusher 160 along the first direction, and the shaft pusher 160 drives the power receiving member 120 to contract along the first direction.

[0162] See also Figure 34-39 The photosensitive drum driving assembly of this embodiment includes a power receiving member 120, a rotating transmission member 122, a photosensitive gear 123, a limiting portion 132, an axial displacement limiting member 127, a force receiving portion 140, a transmission portion, an axial displacement reset member 171 and a moving reset member 190, wherein the transmission portion includes a rotating member 150 and an axial pushing portion 160. The arrangement of the rotating transmission member 122 and the photosensitive gear 123 is the same as that of the first embodiment, and will not be repeated.

[0163] See also Fig.35 In this embodiment, the limiting portion 132 is implemented as a sheet-like covering member fixed to the end of the box body 110 and / or the drum bracket 130, which at least partially covers the pushed portion 152 of the rotating component 150 to prevent the rotating component 150 from axially escaping from the processing box 100.

[0164] See also Fig.36 The inner wall of the rotating transmission member 122 is provided with an axial shift guide portion 129, and the power receiving member 120 is provided with an axial shift matching portion 128. The axial shift guide portion 129 matches the axial shift matching portion 128, so that the power receiving member 120 is connected to the rotating transmission member 122 in a transmission manner in the rotation direction and is movably connected in the axial direction, so that the driving force is transmitted to the photosensitive drum through the rotating transmission member 122, and the power receiving member 120 can be allowed to move along the direction of the rotation axis. Specifically, the axial shift guide portion 129 can be an axial protrusion, and the axial shift matching portion 128 can be an axial groove, or vice versa.

[0165] The force-bearing part 140 is a rod-shaped component, which is arranged at the end of the box body 110 and can move linearly relative to the box body 110. One end of the force-bearing end 141 is the force-bearing end 141, and the other end is the pushing end 142. When the force-bearing end 141 receives the force of the protrusion 203, the force-bearing part 140 moves in a straight line and acts on the pushed part 152 of the rotating part 150 through the pushing end 142.

[0166] The movable reset member 190 is used to push the force receiving portion 140 to return to the initial position when the protrusion 203 leaves the force receiving portion 140. The movable reset member 190 can be a spring, one end of which abuts against the force receiving portion 140 and the other end abuts against the box body 110.

[0167] The rotating component 150 is arranged on the drum bracket 130, and it can rotate around the rotation axis of the power receiving member 120 relative to the drum bracket 130, but cannot move axially along the rotation axis relative to the drum bracket 130. The rotating component 150 includes a circular ring portion 151, a pushed portion 152 and an action portion 153 fixed to each other. The circular ring portion 151 is rotatably arranged on the drum bracket 130, coaxial with the power receiving member 120, and the power receiving member 120 is rotatably arranged in the circular ring portion 151. The action portion 153 is an inclined surface formed on the outer circumferential surface of the circular ring portion 151. The pushed portion 152 is a rod-shaped member with one end connected to the circular ring portion 151, and the other end thereof is used to interact with the pushing end 142 of the force receiving portion 140. In order to facilitate the transmission of the pushed portion 152 and the pushing end 142, the pushed portion 152 and the pushing end 142 can be provided with matching inclined surfaces to make the movement smoother.

[0168] The shaft pusher 160 is arranged on the drum bracket 130, and can move axially relative to the drum bracket 130 and cannot rotate around the rotation axis. Specifically, the shaft pusher 160 is an annular structure, which is sleeved outside the rotating component 150. An axial rib 161 is arranged on the outer circumferential surface of the shaft pusher 160, and a matching slide groove 134 is arranged on the drum bracket 130. The rib 161 is guided by the slide groove 134 and can only move axially. The shaft pusher 160 is provided with an inclined surface that is matched with the action portion 153. The shaft pusher 160 and the rotating component 150 interact with each other through the inclined surface, so that the rotational motion of the rotating component 150 is converted into the axial movement of the shaft pusher 160.

[0169] The axial displacement restoring member 171 is connected to the power receiving member 120 and is used to push the power receiving member 120 to extend and restore along the axial direction. The axial displacement restoring member 171 can be a spring.

[0170] See also Fig.37 and 38 The axial displacement limiter 127 is arranged on the end of the power receiving member 120 extending out of the rotating transmission member 122. Specifically, it can be fixedly engaged on the power receiving member 120 through an annular groove on the end of the power receiving member 120. The axial displacement limiter 127 can abut against the outside of the end of the rotating transmission member 122 to limit the axial limit extension position of the power receiving member 120, thereby preventing the power receiving member 120 from extending too much out of the box body 110 in the axial direction and detaching from the processing box 100.

[0171] The installation process of the process cartridge 100 of this embodiment is as follows:

[0172] The processing box 100 moves along the guide rail 202 until it abuts against the protrusion 203. The force-bearing end 141 of the force-bearing part 140 is pushed by the protrusion 203 so that the force-bearing part 140 moves downward in a straight line, and its pushing end 142 moves accordingly and acts downward on the pushed part 152 of the rotating component 150. The rotating component 150 rotates, and the acting part 153 rotates accordingly and interacts with the axial pushing part 160 through the inclined surface. The axial pushing part 160 is pushed by the acting part 153 to move axially, and the rotational movement of the rotating component 150 is converted into the axial movement of the axial pushing part 160. The axial pushing part 160 pushes the power receiving part 120 to shrink axially toward the inside of the box body 110. The contraction of the power receiving part 120 can avoid the power output part 204 that is about to hit, thereby preventing the two from colliding or getting stuck. The processing box 100 continues to move along the guide rail 202 to the final position, and the power receiving member 120 moves with the processing box 100 to a position that coincides with the axis of the power output member 204, and the two are relative but not meshed. At this time, since the protrusion 203 leaves the force-bearing part 140, the force on the force-bearing part 140 disappears, and it is reset upward under the action of the moving reset member 190, and the force applied by the force-bearing part 140 on the rotating member 150 also disappears. Under the action of the shaft shift reset member 171, the power receiving member 120 and the shaft pusher 160 are both extended and reset in the axial direction, and the power receiving member 120 is meshed with the power output member 204. At the same time, since the action part 153 is pushed by the shaft pusher 160, and the rotating member 150 cannot move in the axial direction, under the interaction of the inclined surface, the axial movement of the shaft pusher 160 is converted into the rotational movement of the rotating member 150, and the rotating member 150 is reset to the initial position.

[0173] See also Fig.39 In the present embodiment, the drum bracket 130 has an arc-shaped outer surface 131 at the front end facing the installation direction, and the shortest distance between the arc-shaped outer surface 131 and the rotation axis of the power receiving member 120 is L2 (that is, the radius of the arc-shaped outer surface 131), and the shortest distance between the pushing end 142 of the force-bearing part 140 and the rotation axis of the power receiving member 120 is L1. When the force-bearing part 140 is in the initial position and after the force-bearing part 140 moves under the force of the protrusion 203, that is, no matter where the force-bearing part 140 is, L1≥L2 is satisfied.

[0174] Since the pushing end 142 is located at the location where the force-bearing part 140 and the rotating part 150 are subjected to force, the pushing end 142 is arranged away from the power receiving part 120 and the position of the tube control part 205 of the mounting part 200, which can prevent the force-bearing part 140 from interfering with the tube control part 205 during movement, so that the processing box 100 can be smoothly installed and used, and the influence of the force-bearing part 140 on the power receiving part 120 when transmitting the driving force can be reduced, which can better ensure the stable transmission of the driving force.

[0175] Embodiment 6

[0176] This embodiment is generally the same as embodiments one to five, and the main differences are: first, in embodiments one to five, the force-bearing portion acts on the convexity, while in this embodiment, the force-bearing portion acts on the guide rail; second, in embodiments one to five, the force-bearing portion is configured to move or rotate on a plane perpendicular to the first direction after receiving the force, while in this embodiment, the force-bearing portion is configured to contract along the first direction after receiving the force.

[0177] In this embodiment, the transmission part only includes a bracket 180, which is sleeved on the periphery of the power receiving member 120. The bracket 180 is engaged with the power receiving member 120 and can move along the axial direction of the photosensitive drum 121a together with the power receiving member 120, and the power receiving member 120 can rotate relative to the bracket 180.

[0178] Specifically, in this embodiment, the bracket 180 is a roughly square convex block, which has a stepped hole 1311a passing through it along the axial direction of the photosensitive drum 121a. One end of the power receiving member 120 is a receiving tooth, and the other end is a cylindrical structure, and a radial protrusion 1312a is provided on the cylindrical structure. The diameter of the radial protrusion 1312a is larger than the small aperture part of the stepped hole 1311a and smaller than the large aperture part of the stepped hole 1311a. The axial direction of the power receiving member 120 is consistent with the axial direction of the photosensitive drum 121a. When the power receiving member 120 is installed in the bracket 180, the cylindrical structure part can pass through the stepped hole 1311a in the bracket 180, and the radial protrusion 1312a can be connected to the larger aperture part of the stepped hole 1311a and is restricted by the small aperture part of the stepped hole 1311a. Figure 45-Figure 48 The power receiving member 120 is also provided with a slot 1312c, which is engaged with the locking member 181. The locking member 181 is larger than the diameter of the stepped hole 1311a, so that the bracket 180 is located between the locking member 181 and the radial protrusion 1312a in the X-axis direction, that is, the bracket 180 cannot move relative to the power receiving member 120, so that when the bracket 180 receives external force and moves along the X-axis direction, it can drive the power receiving member 120 to move together.

[0179] The drum bracket 130 is provided with an extension hole 152a, and the power receiving member 120 can extend through the extension hole 152a of the drum bracket 130 to be transmission-connected with the power output member 204 of the image forming device to rotate the transmission member 122. A slide groove 134 is provided on the side wall of the extension hole 152a, and a slider 1311b is provided on the outer side of the bracket 180. The slider 1311b of the bracket 180 is installed in the slide groove 134 and can move relative to the slide groove 134, so that the bracket 180 is supported on the drum bracket 130 and can drive the power receiving member 120 to move relative to the drum bracket 130.

[0180] like Figure 41-43As shown, the processing box also includes a force-bearing portion 140, which is also arranged at the driving end 111 with the power receiving member 120. Preferably, the force-bearing portion 140 is installed on the drum bracket 130, and the force-bearing portion 140 can move along the axial direction (X-axis direction) of the photosensitive drum 121a on the drum bracket 130, that is, it is consistent with the moving direction of the power receiving member 120, and the distance between the force-bearing portion 140 and the axis of the photosensitive drum 121a remains unchanged during the movement. Specifically, in this embodiment, the force-bearing portion 140 is a block structure with a roughly square structure, and the drum bracket 130 is installed on the box body 110 to form a mounting groove 170b for mounting the force-bearing portion 140 with the box body 110. The mounting groove 170b is recessed on the drum bracket 130 along the axial direction of the photosensitive drum 121a, and the size of the force-bearing portion 140 is slightly smaller than the size of the mounting groove 170b, so that the force-bearing portion 140 can be installed in the mounting groove 170b and move along the axial direction of the photosensitive drum 121a.

[0181] Further, refer to Fig.42 , Fig.43 The processing box further includes a movable reset member 190, by which the force receiving portion 140 can be reset after being moved along the axial direction (X-axis direction) of the photosensitive drum 121a on the drum bracket 130. Specifically, as Fig.42 As shown, in this embodiment, the movable reset member 190 is a spring, and the movable reset member 190 is arranged along the axial direction of the photosensitive drum 121a, and is arranged between the force-bearing part 140 and the box body 110, one end of which abuts on the bottom of the mounting groove 170b along the axial direction of the photosensitive drum 121a, and the other end abuts on the force-bearing part 140, so that when the force-bearing part 140 moves (retracts) along the axial direction of the photosensitive drum 121a relative to the drum bracket 130 and the mounting groove 170b, the force-bearing part 140 presses the movable reset member 190 to store force, so that the movable reset member 190 can provide the force-bearing part 140 with an elastic force to reset along the axial direction of the photosensitive drum 121a. In some embodiments, the movable reset member 190 can also be arranged between the force-bearing part 140 and the drum bracket 130, as long as it can provide a reset elastic force for the force-bearing part 140, and the specific setting position and method are not limited.

[0182] Furthermore, refer to Fig.41The force-bearing portion 140 is also in contact with or connected to the power receiving member 120. The force-bearing portion 140 can receive the action of the control unit 205 of the image forming device. When the force-bearing portion 140 moves along the axial direction (X-axis direction) of the photosensitive drum 121a on the drum bracket 130, it can push the power receiving member 120 to move (retract) on the rotating transmission member 122. Specifically, in this embodiment, a connecting arm 1311c is also provided on the bracket 180. The connecting arm 1311c extends outward from one side of the bracket 180 which is roughly in the shape of a square protrusion. When the bracket 180 is installed in the extension hole 152a of the drum bracket 130, the connecting arm 1311c can extend into the mounting groove 170b of the drum bracket 130. When the force-bearing portion 140 is installed in the mounting groove 170b, the connecting arm 1311c is located between the bottom of the mounting groove 170b and the force-bearing portion 140. The force portion 140 is engaged with the connecting arm 1311c, so that when the force portion 140 moves in the mounting groove 170b along the axial direction (X-axis direction) of the photosensitive drum 121a, it can push the connecting arm 1311c to move in the axial direction (X-axis direction) of the photosensitive drum 121a, that is, the bracket 180 can move in the axial direction (X-axis direction) of the photosensitive drum 121a on the drum bracket 130, thereby driving the power receiving member 120 to retract at one end of the photosensitive drum 121a (moving in the -X-axis direction). Alternatively, in some other embodiments, the force portion 140 can be designed as an integral unit with the connecting arm 1311c, and when the bracket 180 is installed in the extension hole 152a of the drum bracket 130, the connecting arm 1311c and the force portion 140 are extended into the mounting groove 170b for installation.

[0183] Furthermore, a clearance portion 220 is further provided on the guide rail 202 of the mounting portion 200. When the processing cartridge is installed on the mounting portion 200, the processing cartridge moves along the guide rail 202, and the guide rail 202 of the mounting portion 200 squeezes the force-bearing portion 140, that is, the guide rail 202 of the mounting portion 200 presses the force-applying portion 140, thereby pushing the force-bearing portion 140 to move along the axial direction (-X axis direction) of the photosensitive drum 121a, driving the power receiving member 120 to move. The member 120 retracts to prevent the power receiving member 120 from interfering with the power output member 204 of the mounting portion, and when the force receiving member 140 reaches the avoiding portion 220 on the guide rail 202, the force receiving member 140 is not squeezed, and the force receiving member 140 is reset by the elastic force of the moving reset member 190, and the power receiving member 120 is extended on the drum bracket 130 by the elastic force of the axial shift reset member 171, and is engaged with the power output member 204 of the image forming device, thereby transmitting the driving force. Specifically, as Fig.50As shown, in the present embodiment, the avoidance portion 220 is a groove provided on the guide rail 202 of the mounting portion 200. When the processing box is installed on the mounting portion 200, the guide column 170a of the processing box can be inserted into the guide rail 202, so that the processing box can be installed along a specified installation track, and when the processing box is installed, the force-bearing portion 140 also moves along the track on the guide rail 202 of the mounting portion 200, and the avoidance portion 220 is provided on the guide rail 202 of the mounting portion 200 and falls on the track passed by the force-bearing portion 140, so that when the processing box is installed on the mounting portion 200, the force-bearing portion 140 can fall into the avoidance portion 220 along the track, so that the force-bearing portion 140 is avoided, and the power receiving member 120 can extend to engage with the power output member 204 of the image forming device to receive the driving force.

[0184] For further information, see Fig.49 The force-bearing part 140 is provided with a protrusion 161a on the side away from the photosensitive drum 121a. When the force-bearing part 140 is installed in the mounting groove 170b, the protrusion 161a extends out of the drum bracket 130. When the processing box is installed in the mounting part 200, the protrusion 161a is set on the side close to the guide rail 202. The protrusion 161a abuts against the guide rail 202 of the mounting part 200, so that the force-bearing part 140 is pressed and moved, and the power receiving part 120 retracts along the -X axis direction. When the protrusion 161a extends into the avoidance part 220 so that the force-bearing part 140 is not squeezed by the guide rail 202, the power receiving part 120 can extend out of the drum bracket 130 and engage with the power output part 204. Specifically, in this embodiment, the protrusion 161a is a substantially inverted trapezoidal structure protruding from the force-bearing portion 140 in the X-axis direction, that is, the protrusion 161a is provided with transition slopes on both sides along the guide rail 202 to prevent the protrusion 161a from getting stuck when contacting the guide rail 202, so that the guide rail 202 can smoothly press the protrusion 161a. Alternatively, in some other embodiments, the protrusion 161a can also be other shapes protruding from the force-bearing portion 140 in the X-axis direction, which is not limited here.

[0185] The installation process of the processing box provided by the utility model on the image forming device is as follows:

[0186] refer to Figure 51-Figure 52 , align the guide column 170a of the processing box with the guide rail 202 in the mounting part 200, and push the processing box to move along the guide rail 202. At this time, the protrusion 161a of the force-bearing part 140 abuts against the guide rail 202 of the mounting part 200, and the force-bearing part 140 moves axially (-X axis direction) along the photosensitive drum 121a and retracts into the mounting groove 170b, while driving the power receiving part 120 to retract into the rotating transmission part 122 along (-X axis direction), so that there is no interference between the power receiving part 120 and the power output part 204 of the image forming device, so that the processing box can be installed in place, and the power receiving part 120 and the power output part 204 can engage smoothly.

[0187] refer to Fig.52 When the processing box is pushed to continue moving forward on the guide rail 202 of the installation part 200, the force-bearing part 140 reaches the position of the avoiding part 220. At this time, the power receiving part 120 of the processing box corresponds to the position of the power output part 204 in the image forming device, and the force-bearing part 140 is no longer pressed at the position of the avoiding part 220. The force-bearing part 140 is reset in the direction away from the photosensitive drum 121a (+X axis direction) by the elastic force of the movable reset part 190 and returns to the initial position before installation, so that the power receiving part 120 is no longer retracted by force. The power receiving part 120 is extended in the direction away from the photosensitive drum 121a by the elastic force of the axial shift reset part 171. The power receiving part 120 is engaged with the power output part 204 of the image forming device, so that the processing box can receive the driving force of the image forming device, and the installation of the processing box is completed at this time.

[0188] Embodiment 7

[0189] like Figure 53 to Figure 59 As shown, another processing box is provided in this embodiment case, and the difference between this embodiment case and embodiment case six is ​​that: in this embodiment case, the structure of the force-bearing part 140 is different from that in embodiment six, and the force applied to the force-bearing part 140 is no longer the guide rail 202, but the tube control part 205 installed on the side wall of the mounting part 200. When the processing box is installed on the mounting part 200, the force-bearing part 140 is acted on by the tube control part 205, so that the force-bearing part 140 pushes the power receiving part 120 to move in the axial direction of the photosensitive drum 121a and retract into the rotating transmission part 122.

[0190] Specifically, in this embodiment, the force-bearing portion 140 is a convex block disposed on one side of the bracket 180. Preferably, the force-bearing portion 140 and the bracket 180 are an integrally formed structure, which is disposed along the axial direction of the photosensitive drum 121a, and in the axial direction of the photosensitive drum 121a, the side of the force-bearing portion 140 away from the photosensitive drum 121a protrudes from the drum bracket 130, and the portion of the force-bearing portion 140 protruding from the drum bracket 130 is disposed in the +Y axis direction relative to the power receiving member 120. The pipe control 205 is a push block disposed on the mounting portion 200, and correspondingly, the pipe control 205 is disposed in the +Y axis direction relative to the power output member 204 in the mounting portion 200, so as to cooperate with the force-bearing portion 140 to retract the power receiving member 120 without interfering with the power output member 204. Furthermore, a notch 251 is provided on the tube control unit 205. When the processing box is installed in the mounting portion 200, the tube control unit 205 abuts against the protruding portion of the force-bearing portion 140, and can push the force-bearing portion 140 to move in the axial direction of the photosensitive drum 121a, so that the bracket 180 drives the power receiving member 120 to move in the axial direction (-X axis direction) of the photosensitive drum 121a and retract into the rotating transmission member 122. When the processing box continues to be installed in the mounting portion 200, the force-bearing portion 140 can correspond to the position of the notch 251, and the force-bearing portion 140 is no longer pressed by the tube control unit 205. Under the action of the axial shift reset member 171, the bracket 180 is reset, so that the force-bearing portion 140 extends into the notch 251, and the power receiving member 120 extends in the axial direction (+X axis direction) to engage with the power output member 204 to receive the driving force of the image forming device. In some other embodiments, the force-bearing portion 140 may also be detachably assembled with the bracket 180 , as long as the force-bearing portion 140 can drive the bracket 180 to move in the axial direction of the photosensitive drum 121 a , and the specific assembly method is not limited here.

[0191] Further, refer to Figure 57 to Figure 59, the force-bearing portion 140 has a first inclined surface 162 and a second inclined surface 163, and the tube control unit 205 is provided with a third inclined surface 252. When the process cartridge is installed on the mounting portion 200 and the force-bearing portion 140 can correspond to the position of the notch 251, the second inclined surface 163 can fit with the third inclined surface 252, so that the force-bearing portion 140 can smoothly enter the notch 251. Specifically, in the present embodiment, the force-bearing portion 140 is configured as a triangular prism on the side away from the photosensitive drum 121a, so that the first inclined surface 162 and the second inclined surface 163 are provided in the Y-axis direction, and the notch 251 is a concave portion formed by the tube control unit 205 in the X-axis direction, and the third inclined surface 252 is provided on one side. When the process cartridge is installed on the mounting portion 200, the first inclined surface 162 on one side of the force-bearing portion 140 first abuts against the end of the tube control unit 205, and the end of the tube control unit 205 acts on the first inclined surface 162, generating a component force in the -X-axis direction on the force-bearing portion 140, so that The force-bearing portion 140 moves in the -X-axis direction, and the force-bearing portion 140 pushes the power receiving member 120 to move in the -X-axis direction and retract into the rotating transmission member 122. As the processing box continues to be installed, the triangular prism-shaped top of the force-bearing portion 140 abuts against the end of the force-applying portion 250, and when the processing box continues to be installed, the triangular prism-shaped top of the force-bearing portion 140 can completely enter the recess 251 along the third inclined surface 252. At this time, the second inclined surface 163 is in contact with the third inclined surface 252, so that the force-bearing portion 140 is not pressed and can be reset, and the power receiving member 120 extends out and engages with the power output member 204.

[0192] The installation process of the processing box provided by the utility model on the image forming device is as follows:

[0193] refer to Fig.57 , align the processing box guide column 170a with the guide rail 202 in the installation part 200, and push the processing box to move along the guide rail 202. At this time, the tube control part 205 abuts against the force-bearing part 140, specifically, the end of the tube control part 205 abuts against the first inclined surface 162 on one side of the force-bearing part 140, and the force-bearing part 140 is pressed to move along the axial direction (-X axis direction) of the photosensitive drum 121a and retract into the installation groove 170b, and the force-bearing part 140 drives the power receiving part 120 to retract into the rotating transmission part 122 along the axial direction of the photosensitive drum 121a, and there is no interference between the power receiving part 120 and the power output part 204 of the image forming device, so that the processing box can be installed in place, and the power receiving part 120 and the power output part 204 can be smoothly engaged.

[0194] refer to Figure 58 to Figure 59When the processing box is pushed to continue to move forward on the guide rail 202 of the installation part 200, the top of the triangular prism of the force-bearing part 140 abuts against the end of the tube control 205, and when the processing box 100 is further installed, the top of the triangular prism of the force-bearing part 140 moves along the third inclined surface 252 into the recess 251. At this time, the power receiving part 120 of the processing box corresponds to the position of the power output part 204 in the image forming device, and the force-bearing part 140 is no longer pressed at this position, and the force-bearing part 140 is no longer A force is applied to the bracket 180 in the axial direction of the photosensitive drum 121a, so that the power receiving component 120 no longer moves toward the non-driving end 112 of the box body 110, and the power receiving component 120 is reset in the direction away from the photosensitive drum 121a (+X axis direction) through the elastic force of the axial displacement reset component 171, and returns to the initial position before installation. The power receiving component 120 engages with the power output component 204 of the image forming device, so that the processing box receives the driving force of the image forming device, and the processing box installation is now completed.

[0195] In this implementation case, the other structures of the processing box are consistent with those in the first implementation and will not be described here.

[0196] The processing boxes of embodiments six and seven arrange the force-bearing parts to drive the driving head to move in the same direction when receiving the pressing force of the image forming device, that is, the driving head can be directly driven to axially extend and retract, and the extension and retraction of the receiving head driven by the processing box can be controlled without the need for an intermediate force conversion and transmission process, thereby controlling its disengagement and engagement with the driving head of the image forming device, and also allowing the processing box to be smoothly loaded and unloaded from the image forming device, thereby solving the problems in the prior art where the driving head structure is relatively complex and the driving head may be affected by insufficient or unstable driving force received, thereby causing problems such as the processing box installation being stuck and the driving head being unable to engage.

[0197] The above are only some embodiments of the present invention. For those skilled in the art, without departing from the inventive concept of the present invention, several modifications and improvements can be made, or the above technical solutions can be freely combined, including the technical features between the above different embodiments, which all belong to the protection scope of the present invention.
