[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-8 An insulation resistance testing device for a photosensitive drum coating includes a carrier plate 1, a main controller 2 mounted on the carrier plate 1, an insulation resistance tester 3 mounted on the main controller 2, two positionally adapted first fixing plates 4 and second fixing plates 5 mounted on the carrier plate 1, clamping units for holding both ends of the photosensitive drum mounted on the first fixing plates 4 and second fixing plates 5, a drive motor 13 for driving the photosensitive drum to rotate mounted on one side of the first fixing plate 4, a first clamping member 6 connected to the photosensitive drum mounted on one side of the second fixing plate 5, and an adjustment seat 7 mounted on the carrier plate 1 that is positionally adjustable and adapted to the first fixing plates 4 and second fixing plates 5. The unit is provided with a third fixing plate 8 and a fourth fixing plate 9. A charging roller 10 adapted to the photosensitive drum is provided between the third fixing plate 8 and the fourth fixing plate 9. The charging roller 10 can rotate and has a second clamping member 11 at one end. The first clamping member 6 and the second clamping member 11 are both electrically connected to the insulation resistance tester 3. Each clamping unit includes a rotating frame 12 rotatably connected to the side of the first fixing plate 4 or the second fixing plate 5. Both sides of the rotating frame 12 are equipped with telescopic devices 14 with telescopic effect. The telescopic end of the telescopic device 14 is fixedly installed with a clamping frame 15 adapted to the side of the end of the photosensitive drum. The drive motor 13 drives one of the rotating frames 12 to rotate.

[0030] Specifically, when testing the insulation of the coating on the side of the photosensitive drum, the photosensitive drum is placed between the first fixed plate 4 and the second fixed plate 5. The telescopic device 14 is activated, and the telescopic end of the telescopic device 14 moves the clamping frame 15. Multiple clamping frames 15 clamp the two ends of the photosensitive drum. The negative terminal of the insulation resistance tester 3 is connected to the first clamping member 6 through a wire. Then, the charging roller 10 adapted to the photosensitive drum is rotatably installed between the third fixed plate 8 and the fourth fixed plate 9. The positive terminal of the insulation resistance tester 3 is connected to the second clamping member 11 through a wire. The position of the adjusting seat 7 is then adjusted. Adjust the charging roller 10 to bring it closer to the photosensitive drum and maintain the balance between the photosensitive drum and the charging roller 10. Start the drive motor 13 through the main controller 2. The output of the drive motor 13 drives the photosensitive drum to rotate. Observe the rotation of the photosensitive drum and the charging roller 10. Under normal circumstances, the rotation of the photosensitive drum can drive the charging roller 10 to rotate together. Turn on the insulation resistance tester 3, select the appropriate voltage range and resistance range, and after the resistance stabilizes, read and record the stable value. This value is the insulation resistance value of the coating of the photosensitive drum to be tested, so as to achieve the effect of insulation testing of the surface coating of the photosensitive drum.

[0031] As a technical optimization of this utility model, a first sliding block 16 is fixedly installed on the lower part of the second fixed plate 5, and a first sliding groove 17 adapted to the first sliding block 16 is opened on the upper part of the bearing plate 1. A first adjusting threaded rod 18 that is threadedly connected to the first sliding block 16 is passed through and rotatably connected on one side of the bearing plate 1. A first limiting nut 19 is threadedly connected to the side of the first adjusting threaded rod 18.

[0032] Specifically, rotating the first adjusting threaded rod 18 drives the first sliding block 16 to slide within the first sliding groove 17, which can adjust the distance between the second fixed plate 5 and the first fixed plate 4, enabling clamping tests on photosensitive drums of different lengths. Subsequently, locking the first limiting nut 19 limits and fixes the position of the second fixed plate 5, thereby improving the applicability of the testing device.

[0033] As a technical optimization of this utility model, a second sliding block 20 is fixedly installed on the lower part of the adjusting seat 7, and a second sliding groove 21 adapted to the second sliding block 20 is opened on the upper part of the bearing plate 1. A second adjusting threaded rod 22 that is threadedly connected to the second sliding block 20 is passed through and rotatably connected on one side of the bearing plate 1. A second limiting nut 23 is threadedly connected to the side of the second adjusting threaded rod 22.

[0034] Specifically, rotating the second adjusting threaded rod 22 drives the second sliding block 20 to move within the second sliding groove 21. The second sliding block 20 then moves the adjusting seat 7, pushing the charging roller 10 closer to the photosensitive drum. Subsequently, the second limiting nut 23 is locked to fix the position of the adjusting seat 7. This allows for testing of photosensitive drums of different sizes, thus improving the applicability of the testing device.

[0035] As a technical optimization of this utility model, a third sliding block 24 is fixedly installed on the lower part of the fourth fixing plate 9, and a third sliding groove 25 adapted to the third sliding block 24 is opened on the upper part of the adjusting seat 7. A third adjusting threaded rod 26 that is threadedly connected to the third sliding block 24 is passed through and rotatably connected to one end of the adjusting seat 7. A third limiting nut 27 is threadedly connected to the side of the third adjusting threaded rod 26.

[0036] Specifically, rotating the third adjusting threaded rod 26 drives the third sliding block 24 to slide within the third sliding groove 25. The third sliding block 24 moves the fourth fixing plate 9, enabling the installation of charging rollers 10 of different lengths. Tightening the third limiting nut 27 limits and fixes the position of the fourth fixing plate 9, enabling the installation and fixing of charging rollers 10 of different lengths, thus improving the applicability of the testing device.

[0037] As a technical optimization of this utility model, a fourth sliding block 28 is fixedly installed on the lower part of the third fixing plate 8, and a fourth sliding groove 29 adapted to the fourth sliding block 28 is opened on the upper part of the adjusting seat 7. A fourth adjusting threaded rod 30 that is threadedly connected to the fourth sliding block 28 is passed through and rotatably connected to the side of the adjusting seat 7. A fourth limiting nut 31 is threadedly connected to the side of the fourth adjusting threaded rod 30.

[0038] Specifically, rotating the fourth adjusting threaded rod 30 drives the fourth sliding block 28 to slide within the fourth sliding groove 29. The fourth sliding block 28 moves the third fixed plate 8, which adjusts the parallel position between the charging roller 10 and the clamped photosensitive drum, ensuring that the charging roller 10 can be driven to rotate when the photosensitive drum rotates. Then, the fourth limiting nut 31 is locked to limit and fix the position of the third fixed plate 8, thereby improving the testing effect of the testing device.

[0039] As a technical optimization of this utility model, a rotating shaft 32 is rotatably connected through the first fixing plate 4 and the second fixing plate 5. A polygonal limiting groove 33 is opened on the rotating frame 12 and the rotating shaft 32. A matching limiting block 34 is inserted into the limiting groove 33. A fixing bolt 35 with one end threadedly connected to the rotating shaft 32 passes through the limiting block 34.

[0040] Specifically, when it is necessary to install the rotating frame 12 or replace the rotating frame 12 later, align the upper limit groove 33 of the rotating frame 12 of the appropriate size with the upper limit groove 33 of the rotating shaft 32, insert the limiting block 34 into the limiting groove 33, and pass one end of the fixing bolt 35 through the limiting block 34. The other end of the fixing bolt 35 is threadedly connected to the rotating shaft 32, which facilitates the installation or replacement of the rotating frame 12 later.

[0041] As a technical optimization of this utility model, a safety cover 36 is hinged to the upper part of the support plate 1. After the photosensitive drum and charging roller 10 are adjusted, the safety cover 36 is rotated to completely cover the photosensitive drum and charging roller 10. The main controller 2 and insulation resistance tester 3 can only be opened after the safety cover 36 is closed, thereby improving the safety of the testing device.
