Description

Technical Field

[0001] This utility model relates to the field of optical conductor technology, and more specifically, to an adjustable cantilever for OPC wear detection. Background Technology

[0002] In the field of laser printing technology, the organic photoconductor (OPC) drum, as a core component of the toner cartridge, plays a crucial role in print quality and printer lifespan. The OPC drum is made of organic photoconductor material, formed by coating a conductive aluminum cylinder with a specific photoelectric conversion material. Throughout the printing process, steps including charging, exposure, and development all take place on the OPC surface. However, in actual operation, the OPC surface is subjected to pressure and friction from components such as the charging roller, developing roller, cleaning blade, and toner, directly testing its abrasion resistance. Therefore, accurately measuring the abrasion resistance of the OPC surface is essential for assessing its lifespan.

[0003] Currently, there are two main methods in the industry for testing the surface abrasion resistance of OPC: one is to assemble the OPC onto a toner cartridge and perform actual printing tests, which, while intuitive, is time-consuming and consumes a large amount of printing paper; the other method is to use a Taber abrasion tester, but most existing Taber abrasion testers on the market are suitable for testing the abrasion of planar films, lacking specialized testing equipment for the abrasion characteristics of cylindrical OPC surfaces. These existing methods are either inefficient, resulting in high costs due to material waste, or unable to accurately simulate the wear and tear of OPC in real working environments.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in related technologies, this utility model proposes an adjustable cantilever for OPC wear detection to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] An adjustable cantilever for OPC wear detection includes a support base, a positioning column connected to one side of the support base surface, and a telescopic groove opened on the other side. An adjusting column is slidably installed inside the telescopic groove. A drive motor is installed on one side of the positioning column surface, and a rotating shaft is rotatably installed on one side of the adjusting column surface. The output ends of the rotating shaft and the drive motor are both connected to a support cover. An adjusting frame is provided on the surface of the support base, and a detection cantilever is rotatably installed inside the adjusting frame. A cantilever adjustment mechanism is provided between the detection cantilever and the adjusting frame.

[0008] Furthermore, in order to achieve rotational adjustment of the detection cantilever, the cantilever adjustment mechanism includes a rotating shaft connected to one end of the detection cantilever, a transmission worm gear connected to one end of the rotating shaft, and a transmission worm rotatably mounted on one side of the adjustment frame, with the transmission worm meshing with the transmission worm gear.

[0009] Furthermore, in order to adjust the pressure of the grinding wheel when it contacts the OPC drum during testing, a shrinkage groove is opened at one end of the testing cantilever. A lifting rod is slidably installed inside the shrinkage groove, and a bearing plate is connected to the end of the lifting rod. A telescopic spring is provided between the bearing plate and the shrinkage groove.

[0010] Furthermore, in order to perform wear detection on the OPC drum, a transmission groove is opened on the bottom surface of the support plate. An adjusting screw is rotatably installed inside the transmission groove. Adjusting plates are threaded to both sides of the adjusting screw. A clamping plate is rotatably installed on one side of the adjusting plate, and a grinding wheel is clamped and installed on one side of the clamping plate.

[0011] Furthermore, in order to adjust the position of the detection cantilever, an adjustment groove is opened on one side of the surface of the support base, and an adjustment screw is rotatably installed inside the adjustment groove. The bottom of the adjustment frame is threadedly connected to the adjustment screw.

[0012] Furthermore, in order to stably clamp both ends of the OPC drum to be tested within the support cover, the inner wall of the support cover has a mating groove, one side of the mating groove is threaded with a clamping bolt, and the end of the clamping bolt is rotatably mounted with a clamping block, which matches the mating groove.

[0013] Furthermore, in order to achieve elastic adjustment of the adjusting column within the telescopic groove, a return spring is installed inside the telescopic groove. The return spring is connected to one side of the adjusting column, and a control switch is installed on one side of the positioning column.

[0014] The beneficial effects of this invention are as follows: The OPC drum to be tested for wear is stably clamped at both ends within two support covers. Through the cantilever adjustment mechanism, the position of the testing cantilever on the support base and the rotation angle of the cantilever can be freely adjusted. This allows for adjustment of the contact position and pressure between the grinding wheel and the OPC drum surface during wear testing to meet different testing requirements. It can more accurately simulate the wear condition of OPC in actual use. Compared to traditional methods, this design not only reduces testing time and cost but also improves the accuracy and reliability of the measurement results. Attached Figure Description

[0024] 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.

[0025] According to an embodiment of the present invention, an adjustable cantilever for OPC wear detection is provided.

[0026] Example 1:

[0027] like Figures 1-6 As shown, an adjustable cantilever for OPC wear testing according to an embodiment of this utility model includes a metal support base 1. A positioning post 2 is connected to one side of the surface of the support base 1, and a telescopic groove 3 is opened on the other side. An adjusting post 4 is slidably installed inside the telescopic groove 3. A drive motor 5 is installed on one side of the surface of the positioning post 2, and a rotating shaft 6 is rotatably installed on one side of the surface of the adjusting post 4. The output ends of the rotating shaft 6 and the drive motor 5 are both connected to cylindrical support covers 7, which are used to place the two ends of the OPC drum to be tested inside the two support covers 7, and drive it to rotate continuously by the drive motor 5. An adjusting frame 8 is provided on the surface of the support base 1, and a testing cantilever 9 is rotatably installed inside the adjusting frame 8. A cantilever adjustment mechanism 10 is provided between the testing cantilever 9 and the adjusting frame 8, which is used to freely adjust the rotation angle and position of the testing cantilever 9 on the support base 1, so as to facilitate the simulation of different test requirements during OPC wear testing.

[0028] like Figures 1-6As shown, the cantilever adjustment mechanism 10 includes a detection cantilever 9 with one end connected to a rotating shaft 1001, and another end of the rotating shaft 1001 connected to a transmission worm gear 1002. A transmission worm 1003 is rotatably mounted on one side of the adjustment frame 8. The transmission worm 1003 meshes with the transmission worm gear 1002. By rotating the transmission worm 1003, the transmission worm 1003 drives the transmission worm gear 1002 and the rotating shaft 1001 to rotate and adjust, thereby realizing the free adjustment of the rotation angle of the detection cantilever 9. Through the self-locking property of the worm gear, the adjusted detection cantilever 9 can be stably maintained at a fixed angle. One end of the detection cantilever 9 has a contraction groove 1004, and a lifting mechanism is slidably installed inside the contraction groove 1004. The lifting rod 1005 has a support plate 1006 connected to its end. A telescopic spring 1007 is provided between the support plate 1006 and the shrinkage groove 1004. A transmission groove 1008 is opened on the bottom surface of the support plate 1006. An adjusting screw 1009 is rotatably installed inside the transmission groove 1008. A pair of adjusting plates 1010 are threaded to both sides of the adjusting screw 1009. A clamping plate 1011 is rotatably installed on one side of each adjusting plate 1010. A grinding wheel 1012 is clamped on one side of the clamping plate 1011. By rotating the adjusting screw 1009, the adjusting plate 1010 drives the clamping plate 1011 to move closer together and stably clamp the grinding wheel 1012. This is achieved by adjusting the detection cantilever 9. After rotation adjustment, the grinding wheel 1012 contacts the surface of the OPC drum to be tested. Then, by rotating the detection cantilever 9, the bearing plate 1006 compresses the telescopic spring 1007, causing the grinding wheel 1012 to press against the surface of the OPC drum, thereby adjusting the pressure when the grinding wheel 1012 contacts the OPC surface. An adjustment groove 11 is opened on one side of the support base 1. An adjustment screw 12 is rotatably installed inside the adjustment groove 11. The bottom of the adjustment frame 8 is threadedly connected to the adjustment screw 12. By rotating the adjustment screw 12, the adjustment frame 8 moves on the adjustment screw 12, thereby adjusting the position of the adjustment frame 8 and the detection cantilever 9 on the support base 1. The inner wall of the support cover 7 has a matching... The mating groove 13 has a threaded connection to a clamping bolt 14 on one side. A rubber clamping block 15 is rotatably installed at the end of the clamping bolt 14. The clamping block 15 matches the mating groove 13. After placing both ends of the OPC drum to be tested inside the support cover 7, the clamping blocks 15 stably clamp the two ends of the OPC drum by tightening the clamping bolts 14, thereby maintaining the stability of the OPC drum during wear testing. A return spring 16 is installed inside the telescopic groove 3. The return spring 16 is connected to one side of the adjusting column 4 and is used to automatically reset the adjusting column 4 after it slides in the telescopic groove 3 by its own elastic force. A control switch 17 is installed on one side of the positioning column 2 to control the switching of the drive motor 5.

[0029] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0030] In summary, with the help of the above-mentioned technical solution of this utility model, in actual use, the OPC drum to be tested for wear is placed inside the two support covers 7. By turning the clamping bolts 14, the clamping blocks 15 stably clamp the two ends of the OPC drum, thereby maintaining the stability of the OPC drum during wear testing. By rotating the transmission worm gear 1003, the transmission worm gear 1003 drives the transmission worm wheel 1002 and the rotating shaft 1001 to rotate and adjust, thereby realizing the free adjustment of the rotation angle of the detection cantilever 9. By turning the adjusting screw 12, the adjusting frame 8 moves on the adjusting screw 12, thereby adjusting the position of the adjusting frame 8 and the detection cantilever 9 on the support base 1, and adjusting the grinding wheel 1012 at the end of the detection cantilever 9 to the desired position. After positioning the grinding wheel 1012 in the appropriate position, bring it into contact with the surface of the OPC drum. Then, rotate the detection cantilever 9 by turning the transmission worm gear 1003, causing the bearing plate 1006 to compress the telescopic spring 1007, which in turn causes the grinding wheel 1012 to press against the surface of the OPC drum. This adjusts the pressure when the grinding wheel 1012 contacts the OPC surface. Once the required pressure is reached, start the transmission motor 5. The transmission motor 5 continuously drives the OPC drum to rotate through the support cover 7. At this time, through the contact between the OPC drum and the grinding wheel 1012, the OPC drum rotates while simultaneously driving the grinding wheel 1012 to rotate. After the two rotate and rub against each other for a fixed time, remove the OPC drum, weigh it, and compare its weight with that before wear, thus completing the wear test of the OPC drum.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
