Description

Technical Field

[0001] The present invention belongs to the technical field of developing roller cleaning, and particularly relates to an automatic cleaning device for a developing roller. Background Art

[0002] The developing roller is an important core component in the toner cartridge and is one of the components that have the greatest impact on the image density. When producing the developing roller, the mandrel needs to be placed in a mold, and semiconductive rubber is injected into the mold for foaming treatment. After foaming, the semiconductive rubber cures on the surface of the mandrel to form an elastic layer. After trimming the elastic stock head of the developing roller and placing the developing roller on a grinding machine for grinding treatment, rubber chips and burrs will remain on the surface of the developing roller. Therefore, it is necessary to clean the surface of the developing roller.

[0003] For example, the utility model patent with the patent authorization announcement number: CN222175096U discloses an automatic cleaning device for a developing roller, including a base and a developing roller main body. A connecting frame is arranged on the top of the base, and the developing roller main body is located inside the connecting frame. Limiting frames are arranged on both the left and right side walls of the developing roller main body, and threaded shafts extending to the inside thereof are arranged on both the left and right side walls of the connecting frame. For this automatic cleaning device for a developing roller, by setting a cleaning component, the developing liquid in the developing liquid storage tank is sprayed on the surface of the developing roller main body through the cooperation of a fluorine-lined pipe, a fluorine-lined three-way pipe, a fluorine-lined telescopic hose, and an annular spray pipe by starting a micro fluorine-lined pump. The servo motor is started to drive the threaded rod to rotate through the output shaft, so that the threaded block drives the cleaning ring to move to clean the surface of the developing roller main body.

[0004] Based on the retrieval of the patent authorization announcement number and combined with its deficiencies, it is found that:

[0005] For the existing cleaning devices for cleaning developing rollers, it is necessary for workers to install a single developing roller on the cleaning device to achieve the cleaning treatment of the developing roller by the cleaning device. However, in the actual cleaning process, since the number of developing rollers that need to be cleaned in the factory is huge, and the cleaning device can only clean a single developing roller, the cleaning speed of the cleaning device for the developing roller cannot keep up with the manufacturing speed of the developing rollers produced by the factory, thereby affecting the overall production speed and production efficiency of the developing rollers in the factory. Summary of the Invention

Detailed implementation manners

[0037] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features, and their effects of the present invention as follows.

[0038] Please refer to Figures 1 - 14, this embodiment provides an automatic cleaning device for a developing roller, including a frame 1, and further including a placement housing 2. The placement housing 2 is placed on the frame 1. The placement housing 2 is provided with a plurality of placement grooves 201 at equal intervals along its axial direction. The placement grooves 201 are used for placing the developing roller 3. A grasping system and a cleaning component 6 are sequentially arranged along the moving direction of the placement housing 2. The grasping system includes a slide rail 4 and a grasping component 5. The slide rail 4 is horizontally arranged on the top of the frame 1 in parallel. The axial direction of the slide rail 4 is consistent with the sliding direction of the placement housing 2. The grasping component 5 is slidably arranged on the slide rail 4. The grasping component 5 grasps the developing roller 3 in the placement housing 2 to the cleaning component 6 for cleaning treatment. By setting the placement housing 2, the placement housing 2 can place a plurality of developing rollers 3 at one time. The placement housing 2 is placed on the frame 1, so that the placement housing 2 moves to the grasping system. Then, the grasping component 5 grasps all the developing rollers 3 in the placement housing 2 to the cleaning component 6 for cleaning treatment, enabling the cleaning device of this solution to clean a plurality of developing rollers 3 at one time, greatly improving the cleaning speed and efficiency, and solving the problem that in the actual cleaning process, due to the large number of developing rollers 3 that need to be cleaned in the factory, and the cleaning device can only clean a single developing roller 3, resulting in the cleaning speed of the cleaning device for the developing roller 3 not being able to keep up with the manufacturing speed of the developing rollers 3 produced by the factory, thus delaying the overall production speed and efficiency of the developing rollers 3 in the factory.

[0039] Specifically, the grasping component 5 of this solution includes a grasping plate 501 and a plurality of grasping units 7. The grasping plate 501 is slidably arranged on the slide rail 4. The grasping units 7 are arranged on the grasping plate 501 in a liftable manner. The plurality of grasping units 7 are in one-to-one correspondence and match with the plurality of developing rollers 3. Any one of the grasping units 7 is used to grasp the corresponding developing roller 3. By setting the grasping units 7 and the grasping plate 501, the grasping units 7 realize the grasping of the corresponding developing roller 3 by lowering the height. Then, the grasping units 7 return to their original height, and the grasping plate 501 starts to slide along the slide rail 4, enabling the grasping units 7 to move the developing roller 3 to the cleaning component 6 for cleaning treatment.

[0040] Specifically, the grasping component 5 of this solution further includes a plurality of telescopic units 8. The plurality of telescopic units 8 are in one-to-one correspondence and match with the plurality of grasping units 7. Any one of the telescopic units 8 is connected to the corresponding grasping unit 7. The telescopic unit 8 includes a hollow fixed rod 801, a sliding rod 802, and a telescopic spring 803. The fixed rod 801 is vertically arranged on the grasping plate 501. One end of the sliding rod 802 is coaxially slidably arranged in the fixed rod 801. The telescopic spring 803 is arranged in the fixed rod 801. The two ends of the telescopic spring 803 are respectively connected to the sliding rod 802 and the fixed rod 801. The other end of the sliding rod 802 is connected to the grasping unit 7. The telescopic unit 8 is set in this solution. By controlling the sliding of the sliding rod 802, the lifting movement of the grasping unit 7 is realized.

[0041] According to the above embodiments, the grasping unit 7 of this solution is used to grasp the developing roller 3, and the telescopic unit 8 controls the grasping unit 7 to descend to a specified height, facilitating the grasping unit 7 to grasp the developing roller 3; in the actual process of manufacturing the developing roller 3 in a factory, developing rollers 3 with various different diameter sizes will be produced. Therefore, when the developing roller 3 is placed on the placement housing 2, there may be a situation where the diameter sizes of the developing rollers 3 on the placement housing 2 are different from each other; in this case, the heights of the central axes of the respective developing rollers 3 placed on the placement housing 2 are also different from each other. In order to enable the telescopic unit 8 to control the corresponding grasping unit 7 to a specified height and achieve the grasping of the corresponding developing roller 3 by the grasping unit 7, a common solution currently is to provide a number of driving devices. The number of driving devices corresponds to and matches the number of telescopic units 8 one by one. Any one of the driving devices is arranged on the grasping plate 501, and the output end of the driving device is connected to the corresponding sliding rod 802. It should be noted that the driving device needs to have the function of identifying the distance between the grasping unit 7 and the corresponding developing roller 3, and also needs to have the function of controlling the corresponding sliding rod 802 to perform lifting and sliding. By providing the driving device, the lifting movement of the sliding rod 802 to a specified height can be achieved, and thus the control of the height of the grasping unit 7 can be realized;

[0042] However, the setting of the above driving device structure will greatly increase the cost of the entire cleaning equipment. Moreover, the device in this solution is used in a cleaning workshop where the water vapor humidity is relatively high. When measuring the distance between the driving device's gripping unit 7 and the corresponding developing roller 3, due to the presence of water vapor, it greatly affects the measurement accuracy of the distance between the gripping unit 7 and the corresponding developing roller 3. Based on this, in order to reduce the design cost of the entire cleaning equipment and at the same time improve the accuracy of the gripping unit 7 in gripping the corresponding developing roller 3, the gripping assembly 5 in this solution further includes a gripping pump 502, a hydraulic tank 503 filled with hydraulic oil inside, and several hollow connecting rods 504. The fixed rod 801 and the sliding rod 802 together form a hydraulic space with variable volume. It should be noted that the space of the hydraulic space is not interconnected with the internal space of the fixed rod 801 where the telescopic spring 803 is located. The gripping pump 502 and the hydraulic tank 503 are both arranged on the gripping plate 501. The two ends of the gripping pump 502 are respectively connected to the hydraulic tank 503 and any one of the hydraulic spaces. There is a connecting space between adjacent two fixed rods 801. Several connecting rods 504 are in one-to-one correspondence and matching with several connecting spaces. Any one of the connecting rods 504 is arranged in the corresponding connecting space, and the two ends of the connecting rod 504 are respectively interconnected with two hydraulic spaces. By setting the gripping pump 502, when the gripping pump 502 starts to work, it can pump the hydraulic oil in the hydraulic tank 503 into any one of the hydraulic spaces, so that the corresponding telescopic unit 8 starts to work. Until the sliding rod 802 of the telescopic unit 8 slides to the specified height and then stops moving, the volume of this hydraulic space no longer changes. At this time, the gripping pump 502 continues to work, and the overflowing hydraulic oil will flow to the remaining hydraulic spaces through the connecting rod 504. Similarly, until the sliding rods 802 of the remaining telescopic units 8 slide to the specified height and then stop moving, at this time the oil pressure in the hydraulic space will continue to rise. After the oil pressure in the hydraulic space reaches a certain critical value, the gripping pump 502 stops working until all the gripping units 7 reach the specified height positions. It should be noted that this solution is also provided with a hydraulic sensor. The hydraulic sensor is arranged in any one of the hydraulic spaces. When the hydraulic sensor detects that the oil pressure in the hydraulic space reaches the preset value, the hydraulic sensor is communicatively connected to the gripping pump 502 and can control the gripping pump 502 to stop working.

[0043] It should be noted that according to the description of the above embodiments, in order to achieve the function that the sliding rod 802 stops moving after reaching the specified height, the grasping unit 7 of this solution is also provided with an abutting plate 513. The abutting plate 513 is horizontally connected to the sliding rod 802. When the sliding rod 802 moves towards the bottom, the abutting plate 513 slides along with the sliding of the sliding rod 802. It should be noted that after the housing 2 to be placed moves to the bottom of the grasping system on the frame 1, when looking from top to bottom, the abutting plate 513 is located at one end of the corresponding developing roller 3. When the sliding rod 802 moves to the specified height, at this time, the abutting plate 513 is abutted against one end of the developing roller 3, restricting the abutting plate 513 from continuing to move towards the bottom. Similarly, the sliding rod 802 will be restricted from continuing to slide towards the bottom.

[0044] It should also be noted that the housing 2 for placement in this solution is provided with a plurality of placement grooves 201 for placing the developing roller 3. In order to ensure that the housing 2 for placement in this solution can place developing rollers 3 with different diameters, the width of the placement groove 201 is greater than the diameter size of the largest developing roller 3 that can be produced in the factory; at the same time, in order to ensure that after the developing rollers 3 with different diameter sizes are placed in the placement groove 201, the position of the central axis of the developing roller 3 can always be on the same vertical plane as the position of the symmetric central axis of the corresponding placement groove 201, the bottom of the placement groove 201 in this solution is provided with a symmetric arc, and the diameter size of the arc at the bottom of the placement groove 201 is greater than the diameter size of the largest developing roller 3 that can be produced in the factory.

[0045] At the same time, it is also worth noting that in order to ensure that the developing roller 3 does not tilt after the abutting plate 513 abuts against one end of the developing roller 3, two sets of the grasping systems in this solution are movably arranged, and the two sets of grasping systems are arranged oppositely. The two sets of grasping systems are respectively in one-to-one correspondence with the two ends of the developing roller 3. Any one of the grasping systems is used to grasp one end of the developing roller 3. Through such a setting, the abutting plates 513 of the two sets of grasping systems move synchronously and can abut against the two ends of the same developing roller 3 at the same time, and can restrict the developing roller 3 from tilting when it cooperates with the abutting plate 513.

[0046] Specifically, after the sliding rod 802 moves to the specified position, the grasping unit 7 can grasp one end of the corresponding developing roller 3. The specific structure of the grasping unit 7 is as follows: The grasping unit 7 includes a lifting plate 701 and two clamping blocks 702. The lifting plate 701 is connected to the sliding rod 802. The two clamping blocks 702 are slidably arranged at both ends of the lifting plate 701 respectively, and the two clamping blocks 702 can jointly clamp the core shaft of one end of the developing roller 3; By setting the two clamping blocks 702, the two clamping blocks 702 can jointly clamp the core shaft of one end of the developing roller 3 through sliding. It should be noted that the height dimension of the clamping block 702 in this solution is greater than the maximum diameter dimension of the core shaft of the developing roller 3, and the top surface of the clamping block 702 is on the same horizontal plane as the bottom surface of the abutting plate 513; To avoid ambiguity, it should be noted that the grasping of one end of the developing roller 3 by the grasping unit 7 in this solution refers to grasping the core shaft of one end of the developing roller 3.

[0047] Furthermore, in order to control the movement of the clamping block 702, the grasping unit 7 in this solution further includes two driving units 9 and a connecting disk 703. The connecting disk 703 is rotatably arranged on the lifting plate 701. The two driving units 9 are respectively arranged at both ends of the connecting disk 703 relatively. The two driving units 9 are in one-to-one correspondence and matching with the two clamping blocks 702, and any one driving unit 9 is connected to the corresponding clamping block 702; The driving unit 9 includes a main body rod 901 with a hollow interior, a driving rod 902 and a driving spring 903. The main body rod 901 is arranged at one end of the connecting disk 703. One end of the driving rod 902 is slidably arranged in the main body rod 901. The driving spring 903 is arranged in the main body rod 901. The two ends of the driving spring 903 are respectively connected to the main body rod 901 and the driving rod 902. The other end of the driving rod 902 is connected to the clamping block 702; By setting the main body rod 901 and the driving rod 902, when the driving rod 902 starts to slide along the axial direction of the main body rod 901, it will drive the connected clamping block 702 to move, thereby realizing the clamping of the core shaft of the developing roller 3 by the two clamping blocks 702 together. Similarly, since the core shaft diameter dimensions of each developing roller 3 are different, the sliding distances required for the driving rods 902 of each actual driving unit 9 are different. In order to enable each driving unit 9 to control the corresponding clamping block 702 to clamp the corresponding core shaft of the developing roller 3, the commonly used solution at present is to set a number of control devices. The number of control devices is in one-to-one correspondence and matching with the number of driving units 9. Any one control device is arranged on the connecting disk 703, and the output end of the control device is connected to the driving rod 902. It should be noted that the control device needs to have the function of identifying the distance between the clamping block 702 and one end of the core shaft of the developing roller 3, and also needs to have the function of controlling the driving rod 902 to slide. By setting the control device, the sliding of the driving rod 902 can be realized, and then the clamping block 702 can be controlled to clamp the core shaft of the developing roller 3.

[0048] However, the setting of the above control device structure will greatly increase the cost of the entire cleaning equipment. Moreover, the place where this solution's device is used is inside a cleaning workshop, where the water vapor humidity is relatively high. When the control device measures the distance between the clamping block 702 and the core shaft of the corresponding developing roller 3, due to the presence of water vapor, it greatly affects the measurement accuracy of the distance between the clamping block 702 and the core shaft of the corresponding developing roller 3. Based on this, in order to reduce the design cost of the entire cleaning equipment and, at the same time, improve the accuracy of the clamping block 702 grasping the core shaft of the corresponding developing roller 3, the grasping unit 7 of this solution further includes a hollow connecting rod 704 and a connecting hose 705. The driving rod 902 and the main body rod 901 together form a variable-volume space. The two ends of the connecting hose 705 are respectively communicated with the volume space and the hydraulic space. The connecting rod 704 is respectively communicated with the volume spaces of the two driving units 9 of the same grasping unit 7. Through such a setting, first, hydraulic oil will be filled in the hydraulic space. After each hydraulic space is filled, it means that the sliding rod 802 has driven the corresponding grasping unit 7 to slide to the specified height at this time. After the oil pressure in the hydraulic space rises to the specified oil pressure range, the hydraulic oil in the hydraulic space will continue to flow into any one of the volume spaces, causing the corresponding driving unit 9 to start working. Until the driving rod 902 of the driving unit 9 slides to the specified position, after the two clamping blocks 702 jointly clamp the core shaft of the corresponding developing roller 3, the driving rod 902 of this driving unit 9 stops sliding, and the volume of this volume space no longer changes. At this time, the grasping pump 502 continues to work, and the hydraulic oil overflowing in any one of the hydraulic spaces will flow into the corresponding volume space through the connecting hose 705, realizing the driving and clamping of the clamping block 702 by each driving unit 9.

[0049] In addition, it is also worth noting that in order to ensure that after the sliding rods 802 of each telescopic unit 8 slide to the specified height, then control the corresponding driving unit 9 to drive the clamping block 702 to clamp the core shaft of the developing roller 3. The grasping unit 7 of this solution further includes a relief valve 706. The relief valve 706 is hermetically arranged at the connection between the connecting hose 705 and the hydraulic space. By setting the relief valve 706, until the volume in the hydraulic space no longer changes and the oil pressure in the hydraulic space reaches the oil pressure at which the relief valve 706 operates, the relief valve 706 opens, and the hydraulic oil in the hydraulic space will flow through the relief valve 706 into the corresponding volume space.

[0050] Furthermore, since this solution ensures that the two abutting plates 513 jointly and synchronously abut against the two end spindles of the developing roller 3, the developing roller 3 will not tilt when the abutting plates 513 press on it. Therefore, when actually filling hydraulic oil into each hydraulic space, to ensure that the two relatively arranged abutting plates 513 of the two grasping systems can synchronously press on the spindle of the same developing roller 3, it is necessary to ensure that the volume of one hydraulic space does not change before the hydraulic oil can flow into another hydraulic space. Based on this, this solution also includes several limiting valves, which are in one-to-one correspondence with several connecting rods 504. Any limiting valve is arranged inside the corresponding connecting rod 504. The function of the limiting valve not only restricts the hydraulic oil to flow in only one direction, but also can control the limiting valve to open only when the oil pressure in the hydraulic space reaches a certain level, so as to realize the flow of hydraulic oil from one hydraulic space to another. At the same time, it is also worth noting that the oil pressure force required to drive the limiting valve to open is less than the oil pressure force required to drive the overflow valve 706 to open.

[0051] In addition, this solution also includes a lifting unit 10, which includes a lifting cylinder 1001 and a sliding plate 1002. The sliding plate 1002 is slidably arranged on the slide rail 4 along the axial direction of the slide rail 4. The lifting cylinder 1001 is vertically arranged on the sliding plate 1002, and the output end of the lifting cylinder 1001 is connected to the grasping plate 501. Through such a setting, after the grasping unit 7 grasps the spindle of the developing roller 3, the lifting cylinder 1001 starts to work, driving the height of the grasping plate 501 to rise, so that the developing roller 3 is separated from the placing housing 2, which is convenient for the subsequent grasping unit 7 to control the movement of the developing roller 3 to the cleaning assembly 6 for cleaning. It is worth noting that before the grasping unit 7 grasps the spindle of the developing roller 3, the lifting cylinder 1001 controls the height of the grasping plate 501 to drop, which is convenient for the grasping unit 7 to control the height to grasp the spindle of the developing roller 3.

[0052] After the cleaning assembly 6 finishes cleaning the developing roller 3, the grasping unit 7 still needs to control the developing roller 3 to be placed back into the placing housing 2 again. The specific method is as follows: First, the sliding plate 1002 slides to directly above the placing housing 2, and then the lifting cylinder 1001 starts to work, driving the height of the grasping plate 501 to drop, so that the developing roller 3 is completely placed back into the placing housing 2 again. Then, it is necessary to drive the two clamping blocks 702 to jointly release their clamping effect on the spindle of the developing roller 3, and then control the telescopic unit 8 to return to its original position.

[0053] Based on this, in order to achieve the effect of jointly releasing the clamping of the mandrel of the developing roller 3 by the two clamping blocks 702, the grasping assembly 5 of this solution further includes a number of return units, a return housing 509 with a hollow interior, and a return valve 510. The return housing 509 is provided with a return outlet, and the return outlet is in communication with the hydraulic tank 503. The return valve 510 is sealingly arranged at the communication point between the return outlet and the hydraulic tank 503. The return housing 509 is also provided with a number of return inlets. The number of return inlets, the number of volume spaces, and the number of return units are respectively in one-to-one correspondence and match. The return unit includes a return pipe 511 and a return check valve 512. Both ends of the return pipe 511 are respectively in communication with the corresponding volume space and the corresponding return inlet. The return check valve 512 is arranged in the return pipe 511. It should be noted that the function of the return check valve 512 only allows the hydraulic oil located in the volume space to flow into the return housing 509, and the hydraulic oil located in the return housing 509 cannot flow into the volume space. By providing the return valve 510, when the return valve 510 is opened, the return valve 510 releases the sealing relationship between the volume space and the hydraulic tank 503, and the hydraulic oil located in the volume space flows into the hydraulic tank 503. At this time, due to the action of the driving spring 903, the driving rod 902 returns to its original position, so that the two clamping blocks 702 jointly release the clamping effect on the mandrel of the developing roller 3. When the return valve 510 is closed, the return valve 510 re-locks the sealing relationship between the volume space and the hydraulic tank 503, and the hydraulic oil located in the volume space cannot flow into the hydraulic tank 503.

[0054] Similarly, in order to restore the sliding rod 802 to its original position, the grasping assembly 5 of this solution further includes a number of fluid discharge units, a fluid discharge housing 505 with a hollow interior, and a fluid discharge valve 506. The fluid discharge housing 505 is provided with a fluid discharge outlet, and the fluid discharge outlet communicates with the hydraulic tank 503. The fluid discharge valve 506 is sealingly arranged at the connection between the fluid discharge outlet and the hydraulic tank 503. The fluid discharge housing 505 is further provided with a number of fluid discharge inlets. The number of fluid discharge inlets, the number of hydraulic spaces, and the number of fluid discharge units are respectively in one-to-one correspondence and match. The fluid discharge unit includes a fluid discharge pipe 507 and a fluid discharge check valve 508. Both ends of the fluid discharge pipe 507 communicate with the corresponding hydraulic space and the corresponding fluid discharge inlet respectively. The fluid discharge check valve 508 is arranged in the fluid discharge pipe 507. It should be noted that the function of the fluid discharge check valve 508 only allows the hydraulic oil in the hydraulic space to flow into the fluid discharge housing 505, and the hydraulic oil in the fluid discharge housing 505 cannot flow into the hydraulic space. By providing the fluid discharge valve 506, when the fluid discharge valve 506 is opened, the fluid discharge valve 506 releases the sealing relationship between the hydraulic space and the hydraulic tank 503, and the hydraulic oil in the hydraulic space flows into the hydraulic tank 503. At this time, due to the acting force of the telescopic spring 803, the sliding rod 802 returns to its original position again. When the fluid discharge valve 506 is closed, the fluid discharge valve 506 re-locks the sealing relationship between the hydraulic space and the hydraulic tank 503, and the hydraulic oil in the hydraulic space cannot flow into the hydraulic tank 503.

[0055] Specifically, the cleaning assembly 6 of this solution includes a cleaning frame 601, a cleaning motor 602, a cleaning roller 603, a driven roller 604, a conveyor belt 605, and a cleaning belt 606. Along the axis direction of the slide rail 4, the cleaning frame 601 is arranged behind the frame 1, and the cleaning frame 601 is located at the bottom of one end of the slide rail 4. The cleaning roller 603 is rotatably arranged at one end of the cleaning frame 601, the driven roller 604 is rotatably arranged at the other end of the cleaning frame 601, the conveyor belt 605 is rotatably sleeved on the cleaning roller 603 and the driven roller 604, the cleaning belt 606 is sleeved on the top of the conveyor belt 605, the cleaning motor 602 is arranged on the cleaning frame 601, and the output end of the cleaning motor 602 is coaxially connected to the cleaning roller 603 to control the rotation of the cleaning roller 603, thereby driving the cleaning belt 606 to rotate. When the grasping system moves the developing roller 3 directly above the cleaning belt 606, after the developing roller 3 is tangentially matched with the cleaning belt 606, the rotation of the cleaning belt 606 can clean the rubber chips and burrs attached to the developing roller 3, realizing the cleaning treatment of the developing roller 3.

[0056] Further, the cleaning component 6 of the present solution further includes a scraper 607 and a storage box 608 with a hollow interior. The scraper 607 is inclined and arranged inside the cleaning frame 601. One end of the scraper 607 is arranged in mutual contact with the cleaning belt 606. The storage box 608 is arranged inside the cleaning frame 601, and the position of the storage box 608 is at the place where the scraper 607 and the cleaning belt 606 are in mutual contact. By providing the scraper 607, the scraper 607 can scrape off the rubber chips and burrs attached to the cleaning belt 606, realizing the cleaning treatment of the cleaning belt 606. The function of the storage box 608 is to collect the rubber chips and burrs scraped off by the scraper 607.

[0057] According to the above embodiments, in order to improve the cleaning effect of the cleaning belt 606 on the developing roller 3, when the cleaning belt 606 and the developing roller 3 are in mutual contact, the developing roller 3 also needs to rotate. Based on this, it is also required that the grasping unit 7 of the present solution also has a rotating structural effect; specifically, the grasping unit 7 of the present solution further includes a rotating motor 514 and a rotating disk 515. The rotating motor 514 is arranged on the lifting plate 701, the output end of the rotating motor 514 is coaxially connected to the rotating disk 515, the rotating disk 515 is rotatably arranged on the lifting plate 701, and the rotating disk 515 is provided with a rotating groove. The connecting disk 703 is rotatably arranged in the rotating groove; by providing the rotating motor 514, when the rotating motor 514 starts to work, it can drive the rotating disk 515 to rotate, and then realize that the rotating disk 515 drives the connecting disk 703 to rotate synchronously, so as to realize that the grasping unit 7 controls the developing roller 3 to rotate.

[0058] It should be noted that since the gripping unit 7 in this solution needs to ensure that the two clamping blocks 702 are in a state of jointly clamping the core shaft of the developing roller 3 before rotation, based on this, the gripping unit 7 in this solution further includes two locking units 11. The two locking units 11 of the same gripping unit 7 are in one-to-one correspondence and matching with the two driving units 9 of the same gripping unit 7. Any one locking unit 11 is connected to the corresponding driving unit 9. The driving unit 9 further includes a pressing rod 904 and a limiting block 905 connected coaxially. The locking unit 11 includes a locking spring 1101 and a locking rod 1102. The main body rod 901 is provided with a pressing groove and a limiting groove. The two ends of the limiting groove are respectively communicated with the volume space and the pressing groove. The limiting block 905 is slidably arranged in the limiting groove, and the pressing rod 904 is slidably arranged in the pressing groove. Moreover, the outer diameter size of the limiting block 905 is equal to the inner diameter size of the limiting groove, and the outer diameter size of the pressing rod 904 is equal to the inner diameter size of the pressing groove. Such a setting can ensure that the hydraulic oil in the volume space will not overflow from the pressing groove and the limiting groove during the sliding process of the limiting block 905 and the pressing rod 904; and the outer diameter size of the limiting block 905 is greater than the outer diameter size of the pressing rod 904. Such a setting can limit the sliding distance of the pressing rod 904; in addition, the locking rod 1102 is slidably arranged on the connecting disc 703, and the sliding direction of the locking rod 1102 coincides with the sliding direction of the pressing rod 904. The two ends of the locking spring 1101 are respectively connected to the locking rod 1102 and the connecting disc 703. One end of the pressing rod 904 extending out of the pressing groove is connected to one end of the locking rod 1102. The other end of the locking rod 1102 can lock or release its abutting and matching relationship with the rotating disc 515; through such a setting, under normal conditions, due to the acting force of the locking spring 1101, the locking rod 1102 will push the pressing rod 904 to move towards the inside of the pressing groove, so that the locking rod 1102 releases its abutting and matching relationship with the rotating disc 515. Even if the rotating disc 515 rotates at this time, it cannot drive the connecting disc 703 to rotate; only when the volume space is filled with hydraulic oil and the hydraulic oil reaches the rated oil pressure, due to the acting force of the hydraulic oil on the pressing rod 904, the pressing rod 904 will drive the locking rod 1102 to slide, so that the locking rod 1102 locks its abutting and matching relationship with the rotating disc 515. At this time, when the rotating disc 515 rotates, it can drive the connecting disc 703 to rotate together. It should be noted that the hydraulic oil in the volume space of this solution reaching the rated oil pressure means that the hydraulic oil pressure acting force in the volume space has realized the movement of the control driving rod 902, and the two clamping blocks 702 can jointly achieve the clamping effect on the core shaft of the developing roller 3.

[0059] In addition, it should be noted that the abutting plate 513 and the clamping block 702 in this solution are both arranged on the connecting disc 703. Therefore, when the connecting disc 703 starts to rotate, it can drive the abutting plate 513 and the clamping block 702 to rotate together.
