Description

Technical Field

[0001] This utility model relates to the technical field of photosensitive drum testing equipment, specifically a photosensitive drum abrasion resistance testing device. Background Technology

[0002] The photosensitive drum, also known as a toner cartridge, is a core component in office equipment such as laser printers and copiers. Its wear resistance directly affects the lifespan of the equipment and the print quality. During the research and development of the photosensitive drum, it is necessary to conduct precise tests on the wear resistance of the surface coating of the photosensitive drum to ensure that the product quality meets the standards.

[0003] Currently, the abrasion resistance of toner cartridges is measured through printer printing tests. There is no dedicated equipment for testing toner cartridge abrasion resistance. Generally, the abrasion resistance of the toner cartridge is judged by the wear on the surface of the toner cartridge and the print quality after a long period of printing after printing a certain number of standard test pages. Using a printer to test the abrasion resistance of toner cartridges is time-consuming and causes significant paper wear. It generally takes 4 hours to print 10,000 pages, which is time-consuming. For drum cores with better abrasion resistance, it is necessary to print 100,000 pages before the drum core shows significant wear. Testing the abrasion resistance of photosensitive drums is not only time-consuming but also consumes a lot of material, increasing the cost of photosensitive drum abrasion resistance testing. Therefore, there is an urgent need in this field to improve the photosensitive drum abrasion resistance testing device to overcome the shortcomings of the existing technology. Utility Model Content

[0027] Please see Figures 1-6 A photosensitive drum wear resistance testing device includes a base 1 and a toner drum body 8 to be tested. A support seat 2 is provided on the upper part of the base 1. A first fixing plate 3 and a second fixing plate 4 are fixedly installed on the upper part of the support seat 2. A movable fixing plate 5 adapted to the second fixing plate 4 is slidably connected to the upper part of the support seat 2. A rotating shaft 30 is rotatably connected to both the second fixing plate 4 and the movable fixing plate 5. A toner drum clamp 7 adapted to the end of the toner drum body 8 is fixedly installed on one side of the rotating shaft 30. A drive motor 6 for driving the toner drum clamp 7 to rotate is fixedly installed on one of the first fixing plates 3. A friction clamp 9 is provided on the upper part of the base 1, with one side abutting against the side of the toner drum body 8 after being clamped. The device also includes a main controller 10 for controlling the overall device. A first fixing seat 11 is fixedly installed on the upper part of the base 1. A first sliding block 12 is fixedly installed on the lower part of the movable fixing plate 5. A first sliding groove 13 adapted to the first sliding block 12 is opened on the upper part of the first fixing seat 11. A first adjusting threaded rod 14 is rotatably connected through one end of the first fixing seat 11. The first adjusting threaded rod 14 passes through the first sliding block 12 and is threadedly connected to it. The first limiting nut 15 is threadedly connected to the outer side of the first adjusting threaded rod 14. The first turntable 16 is fixedly installed at the outer side of the first adjusting threaded rod 14. The first handle 17 is rotatably connected to one side of the first turntable 16. A coupling 28 is provided between the output end of the drive motor 6 and the rotating shaft 30 on the second fixed plate 4. A bearing assembly 29 is provided on the side of the rotating shaft 30. Several sliding seats 26 are fixedly installed on the upper part of the base 1. The support seat 2 is slidably connected to the upper part of the several sliding seats 26. A three-axis cylinder 27 with telescopic effect is fixedly installed between the support seat 2 and the base 1.

[0028] Specifically, the main controller 10 is equipped with an air pressure adjustment knob, a drive motor 6 speed adjustment knob, a start switch, and a pause switch. The three-axis cylinder 27 is connected to an external air pump pipeline. The air pressure adjustment knob is used to control the pressure of the three-axis cylinder 27. The drive motor 6 speed adjustment knob is used to adjust the speed of the drive motor 6. The start switch is used to turn on the drive motor 6, and the pause switch is used to stop the drive motor 6. When it is necessary to test the wear resistance of the toner cartridge, the toner cartridge clamp 7, which is adapted to the end of the toner cartridge, is fixedly installed on the second fixed plate 4 and the movable fixed plate 5. The toner cartridge clamp 7 can be a pneumatic gripper or the like in the existing known technology. The toner cartridge clamp 7 only needs to be able to clamp the end of the toner cartridge. One end of the toner cartridge is engaged with the toner cartridge clamp 7 position on the second fixed plate 4. By rotating the first handle 17, the first handle 17 drives the first turntable 16 to rotate. The first turntable 16 drives the first adjusting threaded rod 14 to rotate. When the first adjusting threaded rod 14 rotates, it drives the first sliding block 12 to slide in the first sliding groove 13. A sliding block 12 drives the movable fixing plate 5 closer to the second fixing plate 4. The drum clamp 7 on the movable fixing plate 5 is positioned at the other end of the drum and clamps and fixes the other end of the drum. Then, the first limit nut 15 is locked to limit and fix the position of the movable fixing plate 5. Then, the drive motor 6 is turned on. The output end of the drive motor 6 drives the coupling 28 to rotate. The coupling 28 drives the drum body 8 to rotate. The bearing assembly 29 is an aluminum alloy round flange double bearing, which plays a fixed support role and reduces rotational friction. Then, the three-axis cylinder 27 is turned on. The three-axis cylinder 27 drives the support seat 2 to move towards the friction clamp 9. The support seat 2 slides on the upper part of the sliding seat 26. The drum body 8 approaches the friction clamp 9 and contacts and rotates. Timing is started. When the equipment has worked for a specified time, the pause button is pressed. Then, the drum body 8 is removed and the reduction of the film layer on the surface of the drum body 8 is measured. This reduces the cost of abrasion resistance testing of the photosensitive drum and improves the efficiency of abrasion resistance testing of the photosensitive drum.

[0029] As a technical optimization of this utility model, a second fixed seat 18 is fixedly installed on the upper part of the base 1, a second sliding block 19 is provided at one end of the friction clamp 9, a second sliding groove 20 adapted to the second sliding block 19 is opened on the upper part of the second fixed seat 18, a second adjusting threaded rod 21 extending into the second sliding groove 20 is rotatably connected through one end of the second fixed seat 18, the second adjusting threaded rod 21 passes through the second sliding block 19 and is threadedly connected to it, a second limiting nut 22 is threadedly connected to the outer side of the second adjusting threaded rod 21, a second turntable 23 is fixedly installed at the outer end of the second adjusting threaded rod 21, a second handle 24 is rotatably connected to one side of the second turntable 23, a connecting block 25 is fixedly installed at one end of the friction clamp 9, and the connecting block 25 is fixedly installed to the second sliding block 19 by fasteners.

[0030] Specifically, when it is necessary to perform wear resistance tests on different positions on the toner cartridge body 8, the second handle 24 is rotated, which drives the second turntable 23 to rotate. When the second turntable 23 rotates, the second adjusting threaded rod 21 rotates accordingly. The second adjusting threaded rod 21 drives the second sliding block 19 to slide in the second sliding groove 20. The second sliding groove 20 drives the friction clamp 9 to move accordingly. Then, the second limiting nut 22 is locked to limit and fix the position of the friction clamp 9. This allows wear resistance tests to be performed on different positions on the toner cartridge body 8, increasing the range of wear resistance tests on the toner cartridge body 8. The friction clamp 9 is fixedly installed on the upper part of the second sliding block 19 through the cooperation of fasteners and connecting blocks 25, which facilitates the installation or later replacement of the friction clamp 9.
