The cleaning mechanism can clean the pressure plate, the sealing gasket tube and the space formed by the ceramic tile glaze, and can clean up the debris caused by the wear of the grinding balls, the debris caused by the wear of the ceramic tiles and other debris in the sealing gasket tube, thereby making the test results of the present invention more accurate and improving the accuracy of subsequent wear resistance tests on other ceramic tiles. The screening mechanism can screen the grinding balls added to the sealing gasket tube and can screen out the grinding balls that are no longer suitable for the wear resistance test of the ceramic tiles. Before conducting the wear resistance test of the new ceramic tile glaze, the staff no longer needs to re-select the grinding balls suitable for the wear resistance test of the ceramic tiles one by one. They only need to add new grinding balls to the sealing gasket tube to replace the grinding balls that are no longer suitable for the wear resistance test. This can greatly shorten the test time of the present invention, shorten the test cycle of the ceramic tile glaze of the present invention, and solve the problem of cumbersome subsequent operations in the existing ceramic tile test.

[0018] Furthermore, by injecting water into the second through hole, water can flow into the third flow channel through the first flow channel, the second flow channel and the connecting flow channel, and can flush the inner flow channel wall of the third flow channel, thereby flushing the tiles, the sealing gasket tube, the grinding balls and the pressure plate. The flushing water can be discharged from the opened first through hole, and after washing, high-pressure air is introduced from the first through hole. The high-pressure air can blow away the remaining water from the second through hole in the opposite direction and can air-dry the tiles, the sealing gasket tube, the grinding balls and the pressure plate, completing the cleaning of the present invention by the cleaning mechanism. The cleaned sealing gasket tube can make the subsequent tiles more accurate when performing wear resistance testing, and can reduce the influence of debris, waste abrasives and other debris on the wear resistance test of the tiles.

[0019] Furthermore, before the screening mechanism screens the grinding balls, the high-pressure air injected into the sealing gasket cylinder through the first through hole can make the grinding balls approach the inner wall of the sealing gasket cylinder, and then the inflation of the first through hole is stopped, and the air is inflated from the second through hole. When the second through hole is inflated, it is more convenient for the first embedded slot, the first limiting hole, the second embedded slot and the second limiting hole to screen the grinding balls with different degrees of wear, so that the large grinding balls with light wear can be pressed against the first embedded slot, and the large grinding balls with heavy wear and the small grinding balls with light wear are left between the screening outer ring and the screening inner ring, and the small grinding balls with light wear can be pressed against the second embedded slot, while the small grinding balls with heavy wear will pass through the first embedded slot. The grinding balls are then moved through two limiting holes and blown into the screening inner ring. The screening outer ring and the screening inner ring are then retracted into the corresponding outer ring groove and inner ring groove through an external hydraulic device, thereby completing the screening of the grinding balls. The grinding balls remaining in the screening outer ring and the screening inner ring can continue to be used as grinding balls for wear resistance testing, while the grinding balls that are not brought into the outer ring groove and the inner ring groove by the screening outer ring and the screening inner ring are no longer suitable as grinding balls for wear resistance testing. As a result, before conducting a wear resistance test on a new ceramic tile glaze, the staff no longer needs to select the grinding balls one by one. Instead, they only need to select new grinding balls and add them to the sealing gasket cylinder, thereby greatly saving the testing time of the present invention and shortening the testing cycle of the ceramic tile glaze of the present invention.

[0026] like Figures 1 to 6 As shown, an embodiment of the present invention provides a device for testing the wear resistance of ceramic tiles, a device for testing the wear resistance of ceramic tiles, comprising a machine base 100, a grinding and pressing tank 200, a cleaning mechanism 400 and a screening mechanism. The machine base 100 is a support platform that performs periodic rocking motion through an external driving mechanism, and the table plate of the support platform can be a circular plate. A positioning frame 110 is provided on the machine base 100, and the positioning frame 110 is a square frame. There can be multiple positioning frames 110, and the multiple positioning frames 110 are evenly distributed circumferentially on the table surface of the support platform around the center of the table surface of the support platform. The positioning frame 110 is padded with a sealing gasket 120 that is compatible with the positioning frame 110. The sealing gasket 120 can be a rubber sheet. A ceramic tile 130 is placed on the sealing gasket 120, and the ceramic tile 130 is compatible with the positioning frame 110.

[0027] The grinding pressure tank 200 is arranged on the machine base 100 and above the ceramic tile 130. The grinding pressure tank 200 can press the glaze surface of the ceramic tile 130. The grinding pressure tank 200 includes a pressure plate 210, a sealing gasket cylinder 220 and grinding balls. The pressure plate 210 is installed on the machine base 100 by fasteners 300. The fasteners 300 include bolts 310 and straps 320. The straps 320 cover the top of the pressure plate 210. The bottom area of ​​the straps 320 is larger than the top area of ​​the pressure plate 210. The two ends of the straps 320 protrude from the top surface of the pressure plate 210 on a plane parallel to the top surface of the pressure plate 210. The part of the straps 320 protruding from the pressure plate 210 is detachably mounted on the machine base 100 by bolts 310. The sealing gasket cylinder 220 is installed at the bottom of the pressure plate 210 and pressed against the ceramic tile 130. The pressure plate 210 may be a circular plate, and the sealing gasket cylinder 220 may be a rubber cylinder coaxially arranged with the pressure plate 210 .

[0028] A protective tube 211 is fixedly connected to the bottom surface of the pressure plate 210, and the protective tube 211 is sleeved on the outside of the sealing gasket tube 220. The bottom end of the sealing gasket tube 220 abuts against the tile 130, and a gasket ring protrudes from the outside of the end abutting against the tile 130. The gasket ring is located at the bottom end of the protective tube 211 and abuts against the bottom end of the protective tube 211, thereby achieving protection of the sealing gasket tube 220 by the protective tube 211, so that the sealing gasket tube 220 is no longer affected by its own material and can abut against the tile glaze.

[0029] The pressure plate 210 is provided with a first through hole 212 axially communicating with the sealing gasket cylinder 220. Grinding balls are disposed within the sealing gasket cylinder 220 and are used to simulate the wear of the tile glaze. Based on the wear of the different tile glazes, the wear resistance of different tiles 130 can be classified.

[0030] The cleaning mechanism 400 is used to clean the space enclosed by the pressure plate 210 and the sealing gasket tube 220, and can clean the ground tile debris, grinding ball debris, grinding aids and other debris from the sealing gasket tube 220 and the pressure plate 210, thereby reducing the impact on the wear resistance level detection of the new tiles 130 and improving the accuracy of the wear resistance level detection of the new tiles 130.

[0031] The screening mechanism selects grinding balls suitable for re-grinding tile glazes for use in wear resistance testing of new tiles 130. This eliminates the need for workers to individually select grinding balls that meet the next screening requirements from the previously screened grinding press 200, speeding up the testing of tile glaze wear resistance and shortening the testing cycle. It also reduces the waste of grinding balls that meet the requirements.

[0032] It should be noted that, in the present invention, after cleaning by the cleaning mechanism 400 and screening by the screening mechanism, the grinding balls are removed from the tested tiles 130. The grinding balls remaining in the sealing gasket cylinder 220 or the pressure plate 210 are suitable for testing the wear resistance of new tiles 130, while the grinding balls remaining on the tiles 130 are no longer suitable for testing the wear resistance of new tiles 130. This approach eliminates the need for personnel to individually select grinding balls before testing the wear resistance of tile glaze surfaces. Instead, they simply replace the selected grinding balls that are no longer suitable for testing the wear resistance of tiles. This significantly shortens the wear resistance testing cycle for tile glaze surfaces in the present invention.

[0033] The operating principle of the present invention is: When using the present invention to test the wear resistance of a tile 130, the sealing gasket 120 must first be placed in the positioning frame 110, and the tile 130 to be tested must then be placed on the sealing gasket 120. The pressure plate 210, equipped with the sealing gasket cylinder 220, is then placed above the tile 130 to be tested, with the sealing gasket cylinder 220 pressed against the glaze surface of the tile 130 to be tested. The pressure plate 210 is then fixed to the base 100 using the fasteners 300, and an abrasive medium is then placed into the first through hole 212. The grinding media include grinding balls and grinding auxiliary materials. The grinding balls can be selected from two of the steel balls with ball diameters of 5mm, 4mm, 3mm, 2mm, and 1mm. One ball diameter is limited to 5mm and 4mm, and the other ball diameter is limited to 1mm, 2mm, and 3mm. Among them, the steel balls with large ball diameters have large mass and can produce high-intensity impact on the ceramic tile 130, and can simulate heavy wear scenarios such as heavy object scratches or hard object collisions on the ceramic tile 130; while the steel balls with small ball diameters can penetrate into the microstructure of the ceramic tile glaze, can detect the cumulative effect of fine scratches, and reflect the gradual wear in daily use.

[0034] After the grinding balls are placed into the sealing gasket cylinder 220, the first through hole 212 on the pressure plate 210 is closed by the cover, and then the base 100 is started. The base 100 drives the pressure plate 210 and the sealing gasket cylinder 220 to perform periodic horizontal swing motion, thereby starting to test the wear resistance of the tile glaze surface; After the pressure plate 210 and the sealing gasket cylinder 220 have been running for a period of time, the machine base 100 is stopped, and the space enclosed by the sealing gasket cylinder 220 and the pressure plate 210 is cleaned by the cleaning mechanism 400. Then, the grinding balls suitable for the wear resistance test of the new tiles 130 and the grinding balls unsuitable for the wear resistance test of the new tiles 130 are screened out by the screening mechanism.

[0035] After the screening mechanism has finished screening the grinding balls, the sealing gasket cylinder 220 is removed from the ground tile 130. The grinding balls are then removed from the tile 130 and their number and size recorded, completing the testing of the tile under test according to the present invention. However, the screened grinding balls remain stored within the sealing gasket cylinder 220 and the pressure plate 210 for use in the next wear resistance test of a new tile under test 130. This eliminates the need for staff to individually select grinding balls before testing the glaze wear resistance of a new tile under test 130. Staff only need to stock up on grinding balls suitable for the wear resistance test of the new tile 130. This reduces the time required to individually select suitable grinding balls, shortens the testing time, and shortens the testing cycle for the tile glaze according to the present invention. Furthermore, due to the function of the cleaning mechanism 400, when the present invention detects the glaze surface of the new ceramic tile 130, it is no longer affected by debris, sundries, etc. in the detection device, which can make the detection result of the present invention more accurate.

[0036] It should also be noted that while the grinding balls will experience some wear when testing the wear resistance of ceramic tiles 130, the degree of wear will never exceed 1 mm, so there are significant differences in ball size. When recording the size of the grinding balls, it is sufficient to simply record whether the balls are large or small, without having to record the specific diameter. For example, a 4 mm or 5 mm grinding ball is recorded as large, while a ball smaller than 4 mm is recorded as small. Furthermore, only two ball diameters are available for grinding ceramic tile glazes: only one large ball diameter can be selected, and only one small ball diameter can be selected. When testing the wear resistance of ceramic tile glazes, the ball diameters used are already determined. Simply by looking at the grinding balls remaining on the ceramic tile 130 after the test, it is easy to determine whether the grinding balls are large or small.

[0037] In summary, the cleaning mechanism and subsequent processing mechanism provided in the present invention can speed up the detection of the wear resistance of the ceramic tile 130 in the present invention, and has high detection accuracy, which can solve the problem of cumbersome subsequent processing work in the present invention.

[0038] In some embodiments, the cleaning mechanism 400 includes a second through hole 410, a first flow channel 420, a second flow channel 430, a third flow channel 440, and a connecting flow channel 450. The second through hole 410 is provided on one side of the pressure plate 210, and the first flow channel 420 is provided on the bottom of the pressure plate 210, and the first flow channel 420 is connected to the second through hole 410. The second through hole 410 can be an L-shaped through hole, one end of which opens to the side of the pressure plate 210 and the other end opens to the bottom surface of the pressure plate 210. The first flow channel 420 is an annular groove body, which is coaxially arranged with the pressure plate 210 and is close to the outer wall of the pressure plate 210.

[0039] The second flow channel 430 and the third flow channel 440 are respectively defined on the top and bottom annular surfaces of the sealing gasket cylinder 220. Both the second flow channel 430 and the third flow channel 440 are annular grooves. The second flow channel 430 communicates with the first flow channel 420 defined on the bottom surface of the pressure plate 210. A connecting flow channel 450 connects between the second flow channel 430 and the third flow channel 440. The connecting flow channel 450 is provided in a plurality and is evenly distributed along the length of the second flow channel 430.

[0040] In the present invention, the sealing gasket tube 220 is made of rubber. Since the top end of the sealing gasket tube 220 is fixedly connected to the pressure plate 210 and the bottom end only abuts against the tile 130, the material of the bottom end of the sealing gasket tube 220 is softer than that of the pressure plate 210. Also, because a protective tube 211 is provided on the outside of the sealing gasket tube 220, the inner channel wall of the third flow channel 440 is softer than the outer channel wall thereof.

[0041] After the present invention completes the test on the wear resistance of the ceramic tile glaze, the first through hole 212 is opened, and water with a certain pressure is injected into the second through hole 410 through a water pump. The water entering the second through hole 410 can enter the third flow channel 440 through the first flow channel 420, the second flow channel 430 and the connecting flow channel 450. Since the outer side of the sealing gasket tube 220 is reinforced by the protective tube 211, and there are no other obstructions on the outer side of the flow channel wall inside the third flow channel 440, the water entering the third flow channel 440 can bend the flow channel wall inside the third flow channel 440, and can flush out the debris sandwiched inside the third flow channel 440, thereby The third flow channel 440 is connected to the inner tube of the sealing gasket tube 220. The water entering the third flow channel 440 enters the inner tube of the sealing gasket tube 220 through the inner flow channel wall of the third flow channel 440, and then fills the sealing gasket tube 220, and finally flows out from the first through hole 212. In the process of water flowing through the sealing gasket tube 220 and the pressure plate 210, the water can flush the grinding balls, grinding aids, tile 130 debris, grinding ball debris and other debris in the sealing gasket tube 220. The water mixed with debris and other debris can be discharged from the pressure plate 210 and the sealing gasket tube 220 from the first through hole 212, thereby completing the cleaning of the sealing gasket tube 220 of the present invention.

[0042] The clean sealing gasket cylinder 220 can make the subsequent wear resistance test of the ceramic tile 130 more accurate, and can reduce the impact of debris, waste abrasives and other debris on the wear resistance test of the ceramic tile 130.

[0043] After flushing the sealing gasket tube 220, high-pressure air is introduced into the first through hole 212. The high-pressure air flows out of the second through hole 410 in the opposite direction of the water flow, thereby drying the pressure plate 210, the sealing gasket tube 220, and the grinding balls. When the high-pressure air is hot air, the present invention can be dried. The dried sealing gasket tube 220 can be directly used to test the wear resistance of new tiles 130.

[0044] The cleaning mechanism 400 can eliminate the need for workers to clean the sealing gasket cylinder 220, the pressure plate 210 and the grinding balls one by one, thereby reducing the tedious operations that still need to be performed after the inspection of the present invention is completed, and solving the problem of tedious operations.

[0045] In some embodiments, the grinding balls are divided into large grinding balls and small grinding balls. The large grinding balls have a diameter of 5 mm or 4 mm, while the small grinding balls have a diameter of 3 mm, 2 mm, or 1 mm. The specific selection is determined by the physical properties of the test sample, i.e., the ceramic tile 130 to be tested. The large grinding balls are heavier and can produce high-intensity impacts on the ceramic tile glaze, simulating heavy wear and tear, such as scraping by heavy objects or collisions with hard objects. The small grinding balls are smaller and can penetrate deeply into the microstructure of the ceramic tile glaze, enabling the detection of the cumulative effect of fine scratches, reflecting the gradual wear and tear during daily use, and testing the durability of the ceramic tile glaze's microstructure.

[0046] When testing the wear resistance of the glaze surface of the ceramic tile 130 to be tested, large and small grinding balls are arranged in the sealing gasket cylinder 220 , which can detect the wear resistance of the glaze surface of the ceramic tile to be tested under the periodic swinging action of the machine base 100 .

[0047] In some embodiments, as Figures 5 to 10 The screening mechanism includes an outer screening ring 511, an inner screening ring 521, and a third through hole 700. The pressure plate 210 has an outer ring groove 510 and an inner ring groove 520 coaxially disposed with the pressure plate 210 on the side facing the sealing gasket cylinder 220. The outer ring groove 510 has a larger radius than the inner ring groove 520. The outer screening ring 511 and the inner screening ring 521 are slidably disposed in the outer ring groove 510 and the inner ring groove 520, respectively.

[0048] The third through hole 700 is opened on the outer wall of the pressure plate 210. The axial direction of the third through hole 700 is parallel to the bottom plane of the sealing gasket tube 220, and the third through hole 700 is connected with both the outer ring groove 510 and the inner ring groove 520. The hole wall of the third through hole 700 close to the top surface of the pressure plate 210 is connected with the bottom of the outer ring groove 510 and the inner ring groove 520.

[0049] An external hydraulic device is connected to one end of the third through hole 700 away from the outer ring groove 510 and the inner ring groove 520. The external hydraulic device can provide hydraulic pressure to the third through hole 700, thereby controlling the lifting and lowering of the screening outer ring 511 and the screening inner ring 521 in the corresponding outer ring groove 510 and the inner ring groove 520.

[0050] Furthermore, a first ball hole 610 and a second ball hole 620 are respectively formed on the screening outer ring 511 and the screening inner ring 521. The first ball hole 610 is used to screen out large grinding balls suitable for grinding and testing ceramic tile glazes, and the second ball hole 620 is used to screen out small grinding balls suitable for grinding and testing ceramic tile glazes.

[0051] When the machine base 100 performs periodic horizontal swinging motion, the first ball hole 610 can screen out large grinding balls that match it, and the second ball hole 620 can screen out small grinding balls that match it. The large grinding balls and small grinding balls that match the first ball hole 610 and the second ball hole 620 can enter the corresponding ball holes, and after the screening of the grinding balls is completed, they remain in the sealing gasket tube 220 and the pressure plate 210 to be used as grinding balls for the next time, and the grinding balls left after screening are collected for other uses.

[0052] After the glaze surface inspection of the ceramic tile 130 is completed, the present invention does not need to clean the sealing gasket tube 220 and its internal space again, nor does it need to select all the grinding balls. As long as the required new grinding balls are added to the sealing gasket tube 220, the next wear resistance inspection of the ceramic tile 130 can be carried out. This can reduce the time required for inspecting the wear resistance of the ceramic tile 130 and shorten the inspection cycle.

[0053] Furthermore, a first ball hole 610 is defined at an end of the screening outer ring 511 away from the bottom of the outer ring groove 510. A plurality of first ball holes 610 are defined in the screening outer ring 511, and the plurality of first ball holes 610 are evenly spaced about the central axis of the screening outer ring 511. A second ball hole 620 is defined at an end of the screening inner ring 521 away from the bottom of the inner ring groove 520. A plurality of second ball holes 620 are defined in the screening inner ring 521, and the plurality of second ball holes 620 are evenly spaced about the central axis of the screening inner ring 521.

[0054] The first ball hole 610 includes a first engaging slot 611 and a first limiting hole 612. The first engaging slot 611 and the first limiting hole 612 are interconnected and respectively close to the outside and inside of the screening outer ring 511. In a direction perpendicular to the length of the first ball hole 610, the diameter of the first engaging slot 611 is equal to the diameter of the large grinding ball and larger than the diameter of the first limiting hole 612. The second ball hole 620 includes a second engaging slot 621 and a second limiting hole 622. The second engaging slot 621 and the second limiting hole 622 are interconnected and respectively close to the outside and inside of the screening inner ring 521. In a direction perpendicular to the length of the second ball hole 620, the diameter of the second engaging slot 621 is equal to the diameter of the small grinding ball and larger than the diameter of the second limiting hole 622.

[0055] The bottom surfaces of the outer screening ring 511 and the inner screening ring 521 are both annular, and the first and second ball holes 610, 620 are respectively defined in their respective bottom surfaces. Therefore, the cross-section of the first engaging slot 611, perpendicular to the length of the first ball hole 610, is not a complete circle, but rather a figure formed by a long major arc and a line segment enclosing both ends of the long major arc. Similarly, the cross-section of the second engaging slot 621, perpendicular to the length of the second ball hole 620, is a figure formed by another long major arc and a line segment connecting both ends. Driven by an external hydraulic device, the outer screening ring 511 and the inner screening ring 521 can be moved above the ceramic tile 130. Since the extended lines of the long major arcs of the cross-sections of the first and second engaging slots 611, 621 are both tangent to the top surface of the ceramic tile 130, the large grinding balls can now enter the corresponding first engaging slot 611, while the small grinding balls can enter the corresponding second engaging slot 621.

[0056] It should be noted that in order to make the extension lines of the long arc sections of the first embedding slot 611 and the second embedding slot 621 tangent to the upper surface of the tile 130 at the same time, the position of the cross-sectional center of the second ball hole 620 on the screening inner ring 521 should be below the cross-sectional center of the first ball hole 610 on the screening outer ring 511 in the axial direction of the screening inner ring 521.

[0057] In a direction perpendicular to the length of the first ball hole 610, the diameter of the first limiting hole 612 is slightly smaller than the diameter of the first locking slot 611, but larger than the diameter of the small grinding ball. In a direction perpendicular to the length of the second ball hole 620, the diameter of the second limiting hole 622 is slightly smaller than the diameter of the second locking slot 621. When the grinding balls are inspecting the glaze surface of ceramic tiles, they may frequently come into contact with abrasive materials, ceramic tile debris, and other debris, causing wear on the grinding balls. The diameter of the worn grinding balls will be smaller than that of the normal, new grinding balls, but they will have the same diameter as those that can pass through the first limiting hole 612. This allows the first limiting hole 612, which is slightly smaller than the diameter of the first embedding slot 611, to screen the large grinding balls. Only the large grinding balls that are not worn or have very little wear can be blocked by the first limiting hole 612. Both the large and small grinding balls that are severely worn can pass through the first limiting hole 612. Similarly, only the small grinding balls that are severely worn can pass through the second limiting hole 622 and enter the screening inner ring 521.

[0058] When testing the wear resistance of a tile 130 to be tested, the present invention raises the screening outer ring 511 and the screening inner ring 521 via an external hydraulic device, allowing the large and small grinding balls within the sealing gasket cylinder 220 to move freely on the tile glaze surface. The machine base 100 then drives the tile 130 to be tested, the pressure plate 210, and the sealing gasket cylinder 220 to perform periodic rocking motion on a horizontal plane. After the machine base 100 has operated for a period of time, the machine base 100 no longer drives the tile 130 to move. Then, the second through hole 410 is opened and water is passed into the second through hole 410. The water can enter the first flow channel 420, the second flow channel 430, the connecting flow channel 450 and the third flow channel 440, and then the inner flow channel wall of the third flow channel 440 is opened and the water is flushed into the sealing gasket cylinder 220, thereby flushing the sealing gasket cylinder 220, the pressure plate 210, the grinding balls, the inner screening ring 521 and the outer screening ring 511, thereby achieving cleaning of the present invention. After water is introduced into the second through hole 410 for a period of time, the water supply is stopped, and a high-pressure air blower is then used to introduce high-pressure gas into the first through hole 212. The high-pressure gas is eventually discharged from the second through hole 410. During the introduction of high-pressure air, the grinding balls are able to move around the inner wall of the sealing gasket tube 220 under the action of the high-pressure air flow. After the high-pressure air has been introduced for a period of time, the grinding balls will adhere to the inner wall of the sealing gasket tube 220. Afterwards, the outer screening ring 511 and the inner screening ring 521 are gradually lowered by an external hydraulic device. When the extended line of the long superior arc of the cross section of the outer screening ring 511 is tangent to the upper surface of the tile 130, air flow to the first through hole 212 is stopped, and high-pressure gas is instead introduced into the second through hole 410. The high-pressure gas entering the second through hole 410 can rush into the sealing gasket cylinder 220 through the inner flow channel wall of the third flow channel 440. At this time, all the grinding balls in the sealing gasket cylinder 220 can be pushed by the gas. Since the first through hole 212 is a single air outlet, the grinding balls pushed gradually move closer to the first through hole 212. As the grinding balls approach the first through-holes 212, the small grinding balls and the heavily worn large grinding balls can enter the gap between the screening inner ring 521 and the screening outer ring 511 through the first ball holes 610, while the lightly worn large grinding balls can enter the first embedded slots 611 adapted thereto and, under the action of the high-pressure airflow, can be pressed against the first embedded slots 611. The heavily worn small grinding balls can enter the screening inner ring 521 through the second ball holes 620, while the lightly worn small grinding balls can enter the second embedded slots 621 adapted thereto and, under the action of the high-pressure airflow, can be pressed against the second limiting slots. After high-pressure air has been introduced into the second through-hole 410 for a period of time, the external hydraulic device drives the screening outer ring 511 and the screening inner ring 521 to rise to the corresponding outer ring groove 510 and inner ring groove 520. Due to the action of the high-pressure airflow, the large grinding balls in the first embedded groove 611 and the small grinding balls in the second embedded groove 621 are subjected to a force in the direction toward the first through-hole 212, and thus are tightly pressed against the corresponding embedded grooves. When the screening inner ring 521 and the screening outer ring 511 rise, the grinding balls are still subjected to a force in the direction toward the first through-hole 212, so that the grinding balls that meet the screening requirements can enter the outer ring groove 510 and the inner ring groove 520. After the screening outer ring 511 and the screening inner ring 521 bring the grinding balls with less wear into the outer ring groove 510 and the inner ring groove 520, the inflation into the second through hole 410 is stopped, and then the restriction of the fastener 300 on the pressure plate 210 is released, and the remaining grinding balls in the sealing gasket tube 220 are collected, thus completing the complete detection of the ceramic tile 130 according to the present invention.

[0059] It should be noted that when testing the wear resistance of the glaze of the ceramic tile 130, the loss of the grinding balls is very small, and there is a large difference in the ball diameters of the large grinding balls and the small grinding balls. There is no situation where the large grinding balls are worn too severely and become equivalent to the diameter of the small grinding balls. That is, the large grinding balls with a large degree of wear can only be located in the gap between the screening outer ring 511 and the screening inner ring 521, and will not enter the screening inner ring 521 through the second ball hole 620.

[0060] Furthermore, a plurality of first channels 5111 are provided at the bottom of the screening outer ring 511, and the plurality of first channels 5111 are evenly distributed around the central axis of the screening outer ring 511, and the plurality of first channels 5111 and the plurality of first ball holes 610 are arranged in sequence at intervals on the bottom of the screening outer ring 511; a plurality of second channels 5211 are provided at the bottom of the screening inner ring 521, and the plurality of second channels 5211 are evenly distributed around the central axis of the screening inner ring 521, and the plurality of second channels 5211 and the plurality of second ball holes 620 are arranged in sequence at intervals on the bottom of the screening inner ring 521.

[0061] The aperture of the first channel 5111 is smaller than that of the first clamping slot 611 , but larger than that of the second clamping slot 621 . The aperture of the second channel 5211 is smaller than that of the second clamping slot 621 .

[0062] The cross-sectional aperture of the first channel 5111 can be similar to the aperture size of the first limiting hole 612, which makes it easier for large and small grinding balls with severe wear to pass through the screening outer ring 511. The cross-sectional aperture of the second channel 5211 can be similar to the aperture size of the second limiting hole 622, which makes it easier for small grinding balls with severe wear to enter the gap between the screening inner rings 521.

[0063] The provision of the first channel 5111 and the second channel 5211 enables the present invention to more quickly screen out grinding balls that meet the wear resistance test, thereby accelerating the testing process of the present invention.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
