Description

Technical Field

[0001] This utility model relates to the field of testing device technology, and more specifically, to an OPC abrasion resistance testing device that is easy to adjust pressure. Background Technology

[0002] In laser printers, the OPC (Organic Photoconductor) drum is the core photoelectric conversion component of the toner cartridge. Its performance directly affects the printer's imaging quality and equipment lifespan. The OPC drum is usually made of conductive aluminum cylinder as the base material and coated with an organic photoconductor material. The wear resistance of the OPC drum has become an important indicator for measuring its service life and the reliability of the printing equipment. In order to accurately evaluate the wear resistance of OPC materials, it is necessary to design a test device that can simulate the friction and pressure environment under actual working conditions.

[0003] However, the OPC abrasion test device lacks an effective placement mechanism when placing OPC parts, making them prone to displacement or loosening during testing, which affects the accuracy of the test results. At the same time, the OPC abrasion test device lacks an effective pressure detection and adjustment mechanism during testing, making it impossible to monitor and adjust pressure changes in real time during the testing process, which also affects the accuracy of the test results.

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

[0005] To address the problems in related technologies, this utility model proposes an OPC abrasion resistance testing device that facilitates pressure adjustment, thereby solving the problems of existing OPC abrasion resistance testing devices lacking an effective placement mechanism when placing OPC parts and lacking an effective pressure detection and adjustment mechanism.

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

[0007] An OPC abrasion resistance testing device with easy pressure adjustment includes a test platform with a placement mechanism. The placement mechanism includes a motor on one side of the test platform and a bearing seat on the other side of the test platform. A placement cylinder is provided at one end of the bearing seat and the motor. A placement shaft is provided inside the placement cylinder. An OPC component is sleeved on the surface of the placement shaft. An adjustment mechanism is provided on the surface of the OPC component.

[0008] Furthermore, in order to better adjust the pressure of the grinding wheel, the adjustment mechanism includes a grinding wheel on the surface of the OPC component, a placement seat in contact with the inside of the grinding wheel, a cantilever connected to one side of the placement seat, a limiting screw threaded onto the cantilever, one end of the limiting screw in contact with one end of the placement seat, a pressure sensor on the cantilever, a pressure adjustment plate in contact above the pressure sensor, and an electric telescopic rod on the pressure adjustment plate.

[0009] Furthermore, to better secure the electric telescopic pole, a mounting bracket is connected to one end of the pole, and the mounting bracket is connected to the test bench.

[0010] Furthermore, in order to better adjust the cantilever, a rotating rod is provided at one end of the cantilever, and the two ends of the rotating rod are connected to the inner sides of the fixed frame.

[0011] Furthermore, in order to better restrict the pressure regulating plate, guide grooves are provided on both sides of the cantilever, and the interior of the guide grooves is slidably connected to the pressure regulating plate.

[0012] Furthermore, in order to better restrict the placement shaft, a placement opening is provided on the placement cylinder, and a limiting cover is hinged inside the placement opening. A fixing latch is provided between the limiting cover and one side of the placement cylinder.

[0013] Furthermore, to better improve the anti-slip properties of the test platform, multiple support bases are installed underneath the test platform, and anti-slip pads are installed under the support bases.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) The OPC parts to be tested can be placed by the placement mechanism set on the test bench, which can maintain the stable position and posture of the OPC parts and prevent displacement or loosening. This ensures that the contact state between the OPC parts and the grinding wheel remains consistent during the test, thereby ensuring the accuracy of the test results. At the same time, the adjustment mechanism set on the placement mechanism can not only realize the automatic adjustment and precise control of the pressure, but also avoid blind testing caused by the invisibility of the pressure, which greatly improves the controllability of the test process and the accuracy of the test results. It is also beneficial to understand the changes in the test pressure in real time, and the grinding wheel can be separated from the OPC parts when not testing.

[0016] (2) The placement opening and the limiting cover in the placement cylinder make the installation and fixing of OPC parts extremely convenient. At the same time, the limiting cover in the placement opening can improve the convenience of OPC parts installation and ensure its stability during the testing process. Attached Figure Description

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.

A fixing buckle 8 is provided on one side of the limiting cover 7 and the placement cylinder 203 for fixing the limiting cover 7. The placement cylinder 203 contains the placement shaft 204 for placing the OPC part 205. The surface of the placement shaft 204 is fitted with the OPC part 205 for wear resistance testing.

[0028] Example 2:

[0029] like Figures 1-2 , Figure 4 , Figure 5 As shown, according to an embodiment of the present invention, an OPC wear resistance testing device with easy pressure adjustment is provided with an adjustment mechanism 3 on the surface of the OPC component 205. The adjustment mechanism 3 includes a grinding wheel 301 on the surface of the OPC component 205 for performing wear testing on the surface of the OPC component 205. The grinding wheel 301 is in contact with a placement seat 302 for placing the grinding wheel 301. A cantilever 303 is connected to one side of the placement seat 302 for mounting the placement seat 302. A rotating rod 5 is provided at one end of the cantilever 303 for connecting the cantilever 303. The two ends of the rotating rod 5 are connected to the inner sides of the fixed frame 4. Guide grooves 6 are provided on both sides of the cantilever 303 for guiding the pressure adjustment plate 306. The interior of the guide groove 6 is connected to the pressure adjustment plate. A sliding connection is made at 306. A limiting screw 304 is threaded onto the cantilever 303 to limit the grinding wheel 301. One end of the limiting screw 304 contacts the inside of one end of the placement seat 302. A pressure sensor 305 is installed on the cantilever 303 to detect pressure data. The pressure sensor 305 is equipped with a display screen (not shown in the figure) in actual use. The display screen is installed on the fixed frame 4. A pressure regulating plate 306 is in contact above the pressure sensor 305 to regulate the pressure of the pressure sensor 305. An electric telescopic rod 307 is installed on the pressure regulating plate 306 to drive the pressure regulating plate 306 and facilitate pressure adjustment. One end of the electric telescopic rod 307 is connected to the fixed frame 4, and the fixed frame 4 is connected to the test bench 1.

[0030] The electric telescopic pole 307, pressure sensor 305, display screen, and motor 201 are electrically connected to a controller (not shown in the figure) during actual use. The controller is a PLC (programmable logic controller) or a microcontroller. The specific working control program of the controller is written and set according to the actual situation, which is conducive to the precise control of the electrically connected electrical components. The above structure is electrically connected to an external power supply during actual use.

[0031] The electric telescopic rod 307, pressure sensor 305, display screen, grinding wheel 301, motor 201, and OPC component 205 are existing technologies and will not be described in detail. The specific model and specifications need to be selected and determined according to the actual specifications of the device.

[0032] 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.

[0033] In summary, with the help of the above-mentioned technical solution of this utility model, when using it, the operator puts the OPC part 205 to be tested on the placement shaft 204 and inserts the placement shaft 204 into the placement cylinder 203. Then, the placement cylinder 203 is sealed and fixed by the limiting cover 7 and the fixing buckle 8 to ensure that the OPC part 205 will not shift or loosen during the test. At the same time, the operator places the grinding wheel 301 on the placement seat 302 and then adjusts the limiting screw 304 so that the limiting screw 304 contacts the inside of the placement seat 302, which facilitates the restriction of the grinding wheel 301.

[0034] After placement, the placement shaft 204 is rotated by the motor 201 to simulate the movement state of the OPC part 205 in actual use. Then, the pressure regulating plate 306 is driven to move downward or upward by the electric telescopic rod 307. At the same time, one end of the pressure regulating plate 306 moves in the guide groove 6 of the cantilever 303 to ensure that there is no shaking or deviation during the pressure adjustment process. When the pressure regulating plate 306 moves downward, it drives the cantilever 303 to rotate on the rotating rod 5, so that the grinding wheel 301 presses on the surface of the OPC part 205.

[0035] The pressure sensor 305 installed on the cantilever 303 monitors the pressure data applied by the grinding wheel 301 to the OPC component 205 in real time and displays it on the display screen (not shown in the figure). When the pressure sensor 305 detects that the pressure deviates from the set value, the controller automatically adjusts the extension and retraction of the electric telescopic rod 307 to restore the pressure to the target value and ensure the accuracy of the test process.

[0036] After the test, the electric telescopic rod 307 drives the pressure regulating plate 306 to move upward. When the pressure regulating plate 306 moves upward, it drives the cantilever 303 to rotate on the rotating rod 5, so that the grinding wheel 301 is separated from the OPC component 205, avoiding unnecessary wear caused by prolonged contact. The test table 1 is placed securely by the support base 9 and the anti-slip pad 10 to prevent the device from sliding or vibrating during the test, ensuring the reliability of the test results.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
