Description

Technical Field

[0001] The invention relates to the technical field of wear resistance detection, in particular to a wear resistance detection device for a polyurethane screen. Background Art

[0002] Wear resistance testing of designed polyurethane screens is an important part of ensuring the quality of polyurethane screens. Through testing, the wear resistance of the screen can be evaluated to ensure that it can withstand long-term friction and wear in actual use, thereby ensuring the service life and stability of the screen. And the wear resistance test results can provide a scientific basis for the optimization of design and production processes. By understanding the wear resistance of the screen, the material formula and production process can be adjusted to improve the wear resistance and service life of the screen and reduce production costs.

[0003] In the prior art, the wear resistance detection device for polyurethane screen applies pressure to the surface of the screen to be tested through a grinding disc, and then calculates the thickness of the screen surface after thinning after a fixed friction time, so as to judge the wear resistance of the screen to be tested. However, this scheme can only obtain the final performance of the simulated friction in the experimental stage. In actual use, the wear comes from the screen material. Therefore, the reliability and effectiveness of the detection environment will deviate from the actual application. If a large amount of screen material is directly used for field experimental detection, part of the screen material will be screened out and filtered, resulting in a large amount of material preparation in the early stage to be able to simulate completely and realistically, which has high operation difficulty and ultimately the wear state detection accuracy of the screen to be tested itself is also insufficient.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] See also Figures 1 to 7The present invention provides the following technical solutions: a polyurethane screen wear-resistant detection device, comprising a detection device body and a screen to be tested 15, the detection device body comprising a driving mechanism 1, a stacking mechanism 2, a detection component 16 and a vibration component 17, the bottom of the driving mechanism 1 is welded with a fixed seat 6, the bottom of the stacking mechanism 2 is welded with a movable seat 23, the side welder of the movable seat 23 has a positioning column 25, and the movable seat 23 is embedded in the interior of the fixed seat 6 through the positioning column 25, the detection component 16 and the vibration component 17 are both inserted on the inner wall of the stacking mechanism 2, and the detection component 16 and the vibration component 17 are ... One end of the component 16 is welded and fixed to the stacking mechanism 2, one end of the vibration component 17 is rotatably connected to the inner wall of the stacking mechanism 2, the interior of the driving mechanism 1 is divided into a detection cavity 3 and a screening interlayer 4, the screen 15 to be tested is annular in structure as a whole, and the screen 15 to be tested is embedded in the driving mechanism 1, the detection cavity 3 and the screening interlayer 4 are separated by the screen 15 to be tested, the edges of the detection component 16 and the vibration component 17 are both against the inner area of ​​the screen 15 to be tested, and the vibration component 17 is symmetrically installed on both sides of the detection component 16. The wear-resistant detection device is used to test the wear resistance of the polyurethane screen to be tested.

[0029] When the present invention is used, the driving mechanism 1 and the stacking mechanism 2 are first separated, and then the screen mesh 15 to be tested, which is cut into a long strip, is embedded into the interior of the driving mechanism 1 from the side. Since the polyurethane screen mesh itself has a certain elasticity, the screen mesh 15 to be tested can be directly pushed into the interior of the slot 37 from the notch pre-opened on the side of the support ring until a completely annular state is formed and the slot 37 is completely filled, and the installation is completed. After installation, the sieve material for detection is put into the interior of the driving mechanism 1, and the stacking mechanism 2 is pushed to connect it with the driving mechanism 1. At this time, the driving mechanism 1 can be started, and the sieve mesh 15 to be tested installed on the inside is driven by the driving mechanism 1 to rotate. During the rotation process, the surface of the sieve mesh 15 to be tested is continuously contacted and rubbed with the internal sieve material, and the wear state of the sieve mesh 15 to be tested during operation is detected in real time through the detection component 16 on the top, thereby obtaining the wear resistance data of the sieve mesh 15 to be tested.

[0030] In this embodiment, the driving mechanism 1 includes a motor 10 and a housing 11. A support collar 9 is sleeved on one end of the surface of the housing 11. A first bracket 8 is welded to the bottom of the support collar 9. A conical plate 5 is welded to the inner wall of the housing 11. An inner support ring 14 and an outer support ring 12 are welded to the side of the conical plate 5. An inner gear ring 13 is integrally formed on the inner wall of the outer support ring 12. A slot 37 is provided inside the inner support ring 14 and the outer support ring 12. Both sides of the screen 15 to be tested are embedded in the slot 37. A notch is provided on the surface of the inner support ring 14 and the outer support ring 12. The screen 15 to be tested is inserted into the inner support ring 14 and the outer support ring 12 from the notch. The real screen material used in actual application is directly used for continuous wear detection, and the screen material part also includes large-volume materials that can be filtered and small-volume materials that can pass through the screen, ensuring that the experimental test results achieve the purpose of complete simulation, thereby improving the reliability and effectiveness of the final test results.

[0031] Specifically, since the sieve 15 to be tested is supported and connected by the inner support ring 14 and the outer support ring 12, the detection cavity 3 and the screening interlayer 4 can be blocked. When the sieve 15 to be tested is driven to rotate by the driving mechanism 1, the sieve material inside the detection cavity 3 is continuously passed through the surface of the sieve 15 to be tested, and finally falls toward the side of the screening interlayer 4, simulating the wear state during actual use. Since the sieve 15 to be tested is always rotated and transferred as a whole, the internal part of the sieve 15 to be tested will continue to generate friction with the sieve material. The support ring 9 is used to support and fix the motor 10 to ensure that the motor 10 can drive the entire outer shell 11 and the internal sieve 15 to be tested to rotate after the rotation.

[0032] In this embodiment, the stacking mechanism 2 includes a front baffle 18 and a recovery channel 20. An inner convex plate 21 is integrally formed on the inner wall of the front baffle 18. A recovery groove 19 is provided on the inner wall of the front baffle 18. The recovery channel 20 is provided on the inner side of the recovery groove 19. A circulation hole 22 is provided in the middle of the inner convex plate 21. The interior of the recovery channel 20 is partially connected to the circulation hole 22. The inner wall of the front baffle 18 rests on the edge of the outer shell 11 and the outer support ring 12. There are three conical plates 5, and the tip of each conical plate 5 rests on the inner wall of the front baffle 18. The conical plates 5 are used to guide the screened material entering the screening interlayer 4 into the recovery groove 19. A second bracket 24 is welded to the bottom of the outer side of the front baffle 18, and the bottom of the second bracket 24 is welded to the surface of the movable seat 23. The bottom of the first bracket 8 is welded to the surface of the fixed seat 6. A positioning hole 7 is provided on the side of the fixed seat 6, and the positioning column 25 is used to be embedded in the positioning hole 7. The stacking mechanism 2 is used to greatly reduce the amount of screening materials required, and the screened screening materials can be reused. Therefore, even if completely real screening materials are used instead of grinding workpieces to perform wear tests on the surface of the screen 15 to be tested, the ratio of large volume to small volume screening materials in the screening materials can still be kept constant during the entire test process. Therefore, while maintaining a high simulation detection effect, the demand for screening materials is also greatly reduced, reducing the difficulty of early material preparation.

[0033] Specifically, since three groups of conical plates 5 are arranged inside the screening interlayer 4, and the ends of the conical plates 5 are against the front baffle 18, as the conical plates 5 and the outer shell 11 rotate, the sieve materials that pass through the surface of the sieve 15 to be tested can be continuously concentrated inside the screening interlayer 4, and then blocked and pushed by the conical plates 5, so that this part of the sieve materials can be lifted from the side toward the top, and finally transferred to the area of ​​the recovery trough 19, and then fall from the inside of the recovery trough 19 to the inside of the recovery channel 20, and then fall along the recovery channel 20 again from the middle circulation hole 22 into the detection cavity 3, and be remixed with other parts of the sieve materials for testing, so that the sieve materials with less material can always simulate the wear of the real sieve 15 to be tested when screening materials.

[0034] In this embodiment, the detection assembly 16 includes a plug-in shaft 30, a detection sleeve 31 and a support guide roller 33. The detection sleeve 31 is welded on the surface of the plug-in shaft 30. A telescopic hole 32 is opened on the top of the detection sleeve 31. A lifting column 34 is embedded in the telescopic hole 32. A spring rod 35 is inserted at the bottom of the lifting column 34. A pressure module 36 is pressed on the bottom of the spring rod 35. The support guide roller 33 is sleeved on the top of the lifting column 34, and the support guide roller 33 is used to press on the surface of the screen 15 to be tested. The plug-in shaft 30 is fixedly connected to the inner wall of the front baffle 18. The vibration assembly 17 includes a rotating shaft 26 and a cam 27. One end of the rotating shaft 26 is sleeved with a support bearing 29, and the other end of the rotating shaft 26 is welded with a cam 27. The surface of the rotating shaft 26 is keyed to a gear 28. The gear 28 is used to mesh with the inner gear ring 13, the edge of the cam 27 is used to contact the inner wall of the screen 15 to be tested, and one end of the rotating shaft 26 is embedded in the inner wall of the front baffle 18 through the support bearing 29. By driving the vibration component 17 and the detection component 16 in conjunction with the driving mechanism 1, the wear state of the screen 15 to be tested can be monitored and processed in real time in the form of pressure detection, and no additional power equipment is required to ensure that the screen material stuck in the mesh of the screen 15 to be tested can be cleaned and processed, so as to avoid the interference of the stuck material on the pressure data used for detection, so that the final detection result is more accurate.

[0035] Specifically, when the sieve 15 to be tested is driven to rotate by the driving mechanism 1, the inner gear ring 13 on the inner side of the outer support ring 12 can be synchronously matched with the gear 28, thereby driving the rotating shaft 26 to rotate. After the rotating shaft 26 rotates, the cam 27 is driven to rotate. The cam 27 collides with the inner wall of the sieve 15 to be tested quickly and frequently with the help of the raised structure, thereby causing the sieve 15 to vibrate. With the help of the vibration, the part of the sieve material stuck in the mesh falls downward, and the sieve 15 to be tested is subsequently moved to the vibrated cleaned part. When the detection component 16 is in the detection component 16, the detection component 16 presses the top lifting column 34 and the supporting guide roller 33 against the inner side of the screen 15 to be tested through the spring rod 35. As the wear state of the screen 15 to be tested becomes more severe and thinner, the supporting height of the supporting guide roller 33 gradually moves up, and then the pressure data detected by the pressure module 36 at the bottom will gradually decrease, and then the wear state of the current screen 15 to be tested can be judged by the detected pressure data, and the vibration components 17 on both sides can be cooperated to reduce the detection interference of the screen material stuck inside the mesh on the supporting guide roller 33.
