Description

Technical Field

[0001] This utility model relates to the field of printing consumable recycling and reprocessing technology, and in particular to an OPC photosensitive drum recycling and reprocessing device. Background Technology

[0002] With the widespread use of electronic office equipment, the usage of OPC photoconductor drums is increasing daily. Because OPC photoconductor drums gradually wear down during use, their performance deteriorates after reaching a certain point, leading to reduced print quality, thus requiring regular replacement. Currently, most methods for handling discarded OPC photoconductor drums are rather crude, failing to fully utilize their recyclable resources and resulting in waste. Furthermore, some simple processing methods may pollute the environment; existing OPC photoconductor drum recycling technologies have many shortcomings. For example, there is a lack of efficient and non-damaging methods for removing the accessories at both ends of the OPC photoconductor drum; cleaning the inner wall of the OPC photoconductor drum tube is ineffective, failing to completely remove residual toner and impurities; and the polishing process for the outer wall of the OPC photoconductor drum tube is poorly automated, with inconsistent polishing results, making it difficult to meet the quality requirements for reuse. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an OPC photosensitive drum recycling and reprocessing equipment. This equipment enables the scrapped OPC photosensitive drum to be re-polished and cleaned to meet the standard of reuse.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model of OPC photosensitive drum recycling and reprocessing equipment uses a combination of hook and impact components to remove accessories at both ends of the OPC photosensitive drum. It can adapt to the removal needs of different types of accessories, improve the efficiency and success rate of accessory removal, and fix the OPC photosensitive drum with the first cylinder clamp, effectively avoiding damage to the drum body during accessory removal, which is beneficial to the subsequent reprocessing of the drum body and ensures the quality of recycling and reprocessing.

[0017] 2. The OPC photosensitive drum recycling and reprocessing equipment of this utility model has a steel wire brush in the primary cleaning component that, with the cooperation of a power motor and a cylinder clamp, can penetrate deep into the OPC photosensitive drum tube to perform powerful cleaning, initially removing a large amount of toner and impurities attached to the inner wall of the tube, laying a good foundation for subsequent cleaning.

Detailed Implementation

[0030] The present invention will be further described in detail below through specific embodiments. The following embodiments are only descriptive and not limiting, and should not be used to limit the protection scope of the present invention.

[0031] like Figure 1 , Figure 2As shown, an OPC photosensitive drum recycling and reprocessing device includes a first conveying platform 2 and a second conveying platform 10. A feeder 1 is provided on one side of both the first conveying platform 2 and the second conveying platform 10. The feeder 1 on the first conveying platform 2 is used to convey the OPC photosensitive drum 20 to be processed to the first conveying platform 2, and the feeder 1 on the second conveying platform 10 is used to convey the pre-processed OPC photosensitive drum 20 from the first conveying platform 2 to the second conveying platform 10. In this embodiment, the feeder 1 is an extraction conveyor. A pre-processing mechanism 3 is provided on the first conveying platform 2 to remove the accessories 22 at both ends of the OPC photosensitive drum 20. The second conveying platform 10 is sequentially provided with a first cleaning mechanism 11 for cleaning the inner wall of the OPC photosensitive drum 20 tube 21 and a second cleaning mechanism 15 for polishing the outer wall of the OPC photosensitive drum 20 tube 21, respectively cleaning and polishing the inner and outer walls of the OPC photosensitive drum 20 tube 21 to meet the requirements of recycling and reprocessing.

[0032] The pretreatment mechanism 3 includes a hook member 4 and an impact member 9, which are sequentially arranged on one side of the first conveying platform 2. A first cylinder clamp 23 for fixing the OPC photosensitive drum 20 is provided on the first conveying platform 2. The hook member 4 and the impact member 9 work together to remove different types of attachments 22 at both ends of the OPC photosensitive drum 20 using different methods, while the first cylinder clamp 23 ensures the stable fixation of the OPC photosensitive drum 20 during the removal of attachments 22. By using the hook member 4 and the impact member 9 in conjunction with the first cylinder clamp 23, the attachments 22 at both ends of the OPC photosensitive drum 20 can be removed efficiently and stably.

[0033] like Figure 3 , Figure 4 As shown, the hook component 4 includes a pull rod 5, a first cylinder 7, and a second cylinder 8. A hook is provided at the end of the pull rod 5. The first cylinder 7 is movably connected to the pull rod 5 and is used to drive the pull rod 5 up and down. The tail end of the pull rod 5 is movably connected to the second cylinder 8 and is used to drive the pull rod 5 back and forth. The first cylinder clamp 23 fixes the OPC photosensitive drum 20. The hook at the end of the pull rod 5 passes through the baffle 6 and enters the accessory 22 at the tail end of the OPC photosensitive drum 20. Driven by the first cylinder 7 and the second cylinder 8, the hook pulls the accessory 22 off the tail end of the OPC photosensitive drum 20. The accessory 22 hits the baffle 6, which blocks the removed accessory 22, causing it to fall off, and the pull rod 5 disengages from the accessory 22. By controlling the up-and-down and back-and-forth movements of the pull rod 5 by the first cylinder 7 and the second cylinder 8 respectively, the position of the hook can be flexibly adjusted to accurately hook and pull off the accessory 22 at the tail end of the OPC photosensitive drum 20.

[0034] When the OPC photosensitive drum 20 is conveyed to the corresponding position of the hook 4, the first cylinder clamp 23 actuates, firmly fixing the OPC photosensitive drum 20 onto the first conveying platform 2. At this time, the first cylinder 7 drives the pull rod 5 downward, aligning the hook at the end of the pull rod 5 with the tail accessory 22 of the OPC photosensitive drum 20. Then, the second cylinder 8 pushes the pull rod 5 forward, and the hook passes through the baffle 6 and enters the accessory 22. Next, the first cylinder 7 and the second cylinder 8 work together to pull the tail accessory 22 of the OPC photosensitive drum 20 off the drum body. For some ferrule-type tail accessories 22, this hooking method can remove them accurately and efficiently.

[0035] The pull rod 5 can be made of high-strength alloy steel to ensure sufficient strength and resistance to deformation during pulling. The shape of the hook can be customized according to the shape of the accessory 22 at the tail end of the OPC photosensitive drum 20, for example, designed as a hook-shaped structure that matches the slot of accessory 22, facilitating precise hooking of accessory 22. The first cylinder 7 and the second cylinder 8 can be high-precision pneumatic actuators. By controlling their air intake and air pressure, the up-and-down and back-and-forth movement of the pull rod 5 can be precisely controlled to ensure that the hook can accurately hook and pull off accessory 22. In actual operation, parameters can be preset for different models of OPC photosensitive drums 20 so that the cylinder action can be adapted to remove accessories 22 of different specifications.

[0036] baffle 6 is a position adjustment baffle 6, meaning that the position of baffle 6 can be adjusted.

[0037] The striking component 9 includes a telescopic cylinder 24 and a first cylinder clamp 23 that fixes the OPC photosensitive drum 20. The end of the telescopic cylinder 24 extends into the OPC photosensitive drum 20. Through the rapid telescopic movement of the telescopic cylinder 24, the front end of the OPC photosensitive drum 20 is struck, knocking off the front accessory 22. For accessories 22 that are not suitable for removal by hooking, the striking method using the telescopic cylinder 24, with the first cylinder clamp 23 fixing the OPC photosensitive drum 20, ensures the stability of the drum body during the striking process, thereby accurately knocking off the front accessory 22.

[0038] If the attachment 22 at the tail end of the OPC photosensitive drum 20 is not suitable for hooking and removal, such as for attachments 22 that are firmly bonded, the OPC photosensitive drum 20 will be conveyed to the striking element 9. During operation, the extension speed and force of the telescopic cylinder 24 can be adjusted according to the material and bonding strength of the attachment 22 to ensure that the attachment 22 is effectively knocked off without damaging the OPC photosensitive drum 20. For example, for plastic attachments 22 with high bonding strength, the force and number of strikes of the telescopic cylinder 24 can be appropriately increased.

[0039] A buffer rubber pad can be installed at the end of the telescopic cylinder 24. This protects the internal structure of the OPC photosensitive drum 20 from damage during impact and enhances the stability and effectiveness of the impact. The first cylinder clamp 23 can be adjustable to accommodate OPC photosensitive drums 20 of different diameters. When fixing the OPC photosensitive drum 20, a pressure sensor can detect the pressure applied by the clamp to ensure that the pressure is appropriate, ensuring that the photosensitive drum is firmly fixed without deforming the drum body due to excessive pressure.

[0040] like Figure 5 , Figure 6 As shown, the first cleaning mechanism 11 includes a primary cleaning component 12, a secondary cleaning component 13, and a tertiary cleaning component 14, which are sequentially arranged on the second conveying platform 10. Through the sequential action of these three different cleaning components, the inner wall of the OPC photosensitive drum 20 tube 21 is cleaned progressively and thoroughly to achieve a better cleaning effect.

[0041] The primary cleaning component 12 includes a wire brush 26, a second cylinder clamp 25, a third cylinder 27, and a power motor 28. The second cylinder clamp 25 is mounted on the second conveying platform 10 and is used to secure the OPC photosensitive drum 20. The power motor 28 is connected to a rotating shaft, and the wire brush 26 is sleeved on the rotating shaft. The third cylinder 27 drives the power motor 28 to move the wire brush 26 inside the tube 21 of the OPC photosensitive drum 20, allowing the wire brush 26 to penetrate and clean the inner wall of the tube 21. The power motor 28 rotates the wire brush 26, and the insertion depth of the wire brush 26 is adjusted by the third cylinder 27.

[0042] When the OPC photosensitive drum 20 is conveyed to the primary cleaning component 12, the second cylinder clamp 25 presses the OPC photosensitive drum 20 to prevent it from shaking during the cleaning process. The power motor 28 starts, driving the connected rotating shaft to rotate, which in turn causes the wire brush 26 sleeved on the rotating shaft to rotate at high speed. The third cylinder 27 adjusts the insertion depth of the wire brush 26, so that the wire brush 26 fully contacts the inner wall of the OPC photosensitive drum 20 tube 21, cleaning away the large amount of toner and larger particulate impurities adhering to the inner wall.

[0043] The hardness and length of the steel wire brush 26 can be selected according to the material of the inner wall of the OPC photosensitive drum 20 tube 21 and the amount of impurities. For cases where the inner wall material is hard and there are many impurities, harder and longer bristles can be selected. The third cylinder 27 can be a servo cylinder, which, through precise control of its stroke, allows the steel wire brush 26 to penetrate deeply and fully contact the inner wall of the OPC photosensitive drum 20 tube 21. The power motor 28 can be equipped with a speed adjustment device to adjust the rotation speed of the steel wire brush 26 according to the actual cleaning effect, achieving the best cleaning efficiency.

[0044] The secondary cleaning component 13 includes a nylon brush 30, a fourth cylinder clamp 29, a fifth cylinder 31, and a power motor 28. The fourth cylinder clamp 29 is mounted on the second conveying platform 10 and is used to press and hold the OPC photosensitive drum 20. The power motor 28 is connected to a rotating shaft, and the nylon brush 30 is sleeved on the rotating shaft. The cylinder clamp pushes the power motor 28 to move the nylon brush 30 inside the tube 21 of the OPC photosensitive drum 20, cleaning the inner wall of the tube 21. The power motor 28 drives the nylon brush 30 to rotate, and the fifth cylinder 31 adjusts the insertion depth of the wire brush 26, allowing the wire brush 26 to penetrate deeply and contact the inner wall of the tube 21 of the OPC photosensitive drum 20. The nylon brush 30 is softer than the steel wire brush 26. After the initial cleaning with the steel wire brush 26, the secondary cleaning component 13 uses the nylon brush 30 to further clean the inner wall of the tube 21. This allows for better removal of residual fine impurities and minor stains without damaging the inner wall of the drum, further improving the cleanliness of the inner wall of the tube 21. For stubborn stains that have formed on the inner wall of the tube 21 due to long-term use, the nylon brush 30 can remove them through closer contact and rotating friction.

[0045] The bristle density and softness of the nylon brush 30 need to be carefully selected to ensure that it can effectively remove the residue that the steel wire brush 26 failed to clean, without scratching the inner wall of the OPC photosensitive drum 20 tube 21. Similar to the primary cleaning component 12, the power motor 28 is also equipped with a speed adjustment device, and the fifth cylinder 31 is also a servo cylinder to precisely control the working position and force of the nylon brush 30. In addition, an appropriate amount of cleaning fluid can be added to the bristles of the nylon brush 30 to further improve the cleaning effect.

[0046] The third-stage cleaning component 14 includes a high-pressure air source 35, a high-pressure nozzle 33, a sixth cylinder clamp 32, and a seventh cylinder 34. The sixth cylinder clamp 32 is mounted on the second conveying platform 10 and clamps the OPC photosensitive drum 20. The high-pressure air source 35 is connected to the high-pressure nozzle 33. The seventh cylinder 34 drives the high-pressure nozzle 33 to move, blowing high-pressure gas into the OPC photosensitive drum 20 to clean the residual debris in the inner wall of the OPC photosensitive drum 20 tube 21. After cleaning by the first-stage cleaning component 12 and the second-stage cleaning component 13, the third-stage cleaning component 14 uses the powerful impact of high-pressure gas to blow out the residual micro-debris that is difficult to clean deep inside the inner wall of the OPC photosensitive drum 20 tube 21, ensuring that the cleanliness of the inner wall of the OPC photosensitive drum 20 tube 21 reaches a high standard.

[0047] After secondary cleaning, the OPC photosensitive drum 20 reaches the position of the tertiary cleaning component 14. The sixth cylinder clamp 32 presses the OPC photosensitive drum 20 again, and the high-pressure air source 35 delivers high-pressure gas to the high-pressure nozzle 33. The high-pressure nozzle 33 accurately blows the gas into the interior of the OPC photosensitive drum 20, blowing out the fine debris remaining after primary and secondary cleaning. In actual operation, the pressure of the high-pressure air source 35 can be adjusted according to the cleaning requirements to ensure effective removal of all residual debris from the inner wall of the tube 21. For OPC photosensitive drums 20 with higher cleaning requirements, the pressure of the high-pressure air source 35 can be appropriately increased.

[0048] The high-pressure air source 35 can be an air compressor. To ensure the cleanliness of the blown gas, a gas filter can be installed at the rear end of the air compressor to remove impurity particles from the gas and prevent them from re-contaminating the OPC photosensitive drum 20. The nozzle shape and angle of the high-pressure nozzle 33 can be optimized according to the internal structure of the OPC photosensitive drum 20 tube 21 so that the high-pressure gas can be blown evenly to all parts of the inner wall of the tube 21.

[0049] like Figure 7 As shown, the second cleaning mechanism 15 includes a strip-shaped paper tray 16 wound with a polishing paper strip, a first driving pressure roller 17, a second driving pressure roller 18, and a bidirectional driving pressure roller 19. The polishing paper strip passes through the gap between the first driving pressure roller 17, the second driving pressure roller 18, and the OPC photosensitive drum 20, then passes through the bidirectional driving pressure roller 19 and falls into the waste paper bag recycling bin. The transmission direction of the polishing paper strip is opposite to the rotation direction of the OPC photosensitive drum 20. This mechanism, through the cooperation of different driving pressure rollers, ensures that the polishing paper strip makes full contact with the outer wall of the OPC photosensitive drum 20 tube 21 and generates relative motion, achieving polishing of the outer wall of the tube 21. The reverse transmission of the polishing paper strip helps to improve the polishing effect. The polished waste paper falls into the recycling bin for centralized processing. By using reverse polishing, wear marks and other defects on the outer wall of the OPC photosensitive drum 20 tube 21 are effectively removed, achieving fine polishing of the outer wall.

[0050] The OPC photosensitive drum 20 is conveyed from the second conveyor platform 10 to the second cleaning mechanism 15. The mechanism arm places the OPC photosensitive drum 20 onto the first drive roller 17 and the second drive roller 18. A strip paper reel 16, wound with abrasive paper, begins to release the abrasive paper strip. The abrasive paper strip passes sequentially through the gap between the first drive roller 17, the second drive roller 18, and the OPC photosensitive drum 20. At this time, the first drive roller 17 and the second drive roller 18 rotate, causing the abrasive paper strip to make close contact with the outer wall of the OPC photosensitive drum 20 tube 21. Simultaneously, the OPC photosensitive drum 20 itself also rotates. Since the transmission direction of the abrasive paper strip is opposite to the rotation direction of the OPC photosensitive drum 20, relative motion occurs between them, thereby abrading the outer wall of the OPC photosensitive drum 20 tube 21. After passing through the bidirectional drive roller 19, the abrasive paper strip falls into the waste paper bag recycling bin. During operation, the rotation speeds of the first drive roller 17, the second drive roller 18, and the bidirectional drive roller 19 can be adjusted according to the actual condition of the outer wall of the OPC photosensitive drum 20 tube 21 to control the polishing force and effect. For OPC photosensitive drums 20 with numerous defects on the outer wall of the tube 21, the roller speed can be appropriately increased to enhance the polishing effect. Polishing paper tapes of different roughness can also be replaced as needed to meet different polishing requirements. For OPC photosensitive drums 20 with severe surface damage, coarse polishing can be performed first using a higher roughness polishing paper tape, followed by finer polishing with a finer tape.

[0051] In practical applications, the strip paper tray 16 can be designed as an automatic winding structure. When the polishing paper strip reaches a certain length, triggering the corresponding length sensor, the equipment control system automatically starts the winding device to replace the polishing paper strip, achieving automatic supply of polishing paper strip and improving the continuity and automation of equipment operation. The material selection of the polishing paper strip depends on the specific condition of the outer wall of the OPC photosensitive drum 20 tube 21. For severely worn outer walls, coarser sandpaper-like polishing paper strips can be used to enhance polishing force; for relatively minor worn outer walls, finer-grit abrasive paper can be used to achieve fine polishing and avoid over-polishing that could damage the photosensitive drum.

[0052] The surfaces of the first and second drive rollers 17 and 18 that contact the polishing paper belt can be made of rubber with a certain degree of elasticity and friction. The rubber material increases the friction between the polishing paper belt and the roller, ensuring that the polishing paper belt, after being drawn from the strip paper tray 16, stably passes through the gap between itself and the OPC photosensitive drum 20 without slippage or deviation. Simultaneously, torque sensors can be installed at the shafts of the first and second drive rollers 17 and 18 to monitor the torque experienced by the drive rollers as they drive the polishing paper belt. When abnormal torque changes occur, such as jamming or excessive tension in the polishing paper belt, the torque sensor feeds a signal back to the equipment control system. The system then promptly adjusts the speed of the drive rollers or regulates the tension of the polishing paper belt to ensure the stability of the polishing paper belt transmission.

[0053] The bidirectional drive pressure roller 19 plays a crucial role in the transmission of the polishing paper belt. It must ensure the paper belt continues to move stably backward after contacting the OPC photosensitive drum 20, and also ensure the paper belt passes smoothly through itself and falls into the waste paper bag recycling bin. To better adapt to the transmission needs of the polishing paper belt under different conditions, the bidirectional drive pressure roller 19 can be designed with a pressure-adaptive structure. For example, pressure sensors can be installed at both ends of the bidirectional drive pressure roller 19 to detect the tension of the polishing paper belt in real time. When the tension of the polishing paper belt changes, the bidirectional drive pressure roller 19 automatically adjusts the pressure on the polishing paper belt through its internal pressure regulating device, ensuring the polishing paper belt is always in a suitable transmission state and preventing problems such as the polishing paper belt becoming loose and affecting the polishing effect, or the paper breaking due to excessive tension.

[0054] The working principle of this utility model:

[0055] The OPC photosensitive drum 20 to be processed in the workpiece hopper is conveyed to the first conveyor platform 2 via the feeder 1. The hooking device 4 and striking device 9 on the first conveyor platform 2 pre-process the OPC photosensitive drum 20 by hooking off and striking off the accessories 22 at the front and rear ends of the tube body 21 of the OPC photosensitive drum 20, and then the OPC photosensitive drum is placed in the workpiece cage. The OPC photosensitive drum in the workpiece cage is then placed in the workpiece hopper of the melting tank car. The pre-processed OPC photosensitive drum 20 is then conveyed to the first conveyor platform 2 via the feeder 1. The second conveying platform 10 cleans the inner wall of the tube 21 of the OPC photosensitive drum 20 through the first-level cleaning component 12, the second-level cleaning component 13, and the third-level cleaning component 14 respectively. The OPC photosensitive drum is taken out from the second conveying platform 10 by the robot arm 36 and placed in the polishing station of the second cleaning mechanism 15 by the robot arm 36. Then, the outer wall of the tube 21 of the OPC photosensitive drum 20 is polished by the second cleaning mechanism 15. The processed OPC photosensitive drum 20 is stacked on the stacking rack by the robot arm 36.
