Description

Technical Field

[0001] The invention relates to the technical field of ball table cloth textile fabric production, in particular to a ball table cloth textile fabric surface pilling testing device and method. Background Art

[0002] During the production process of tablecloth textile fabrics, surface pilling tests are required to roughly estimate the service life of the fabrics. The Martindale method is primarily used for testing. The Martindale method involves subjecting a circular tablecloth sample to a Lissajous figure-like relative motion (multi-directional friction) against a standard abrasive (usually standard wool felt or a specific fabric) under a specified pressure. The sample is then compared with the standard pilling sample to determine the pilling rating of the tested circular sample. This method is simple to operate and provides accurate test results.

[0003] However, in the actual test process, only friction is performed, and there is no simulation of the actual use of the table tennis table cloth textile fabric. In particular, during the use of the table tennis table cloth textile fabric, collisions between the table tennis balls and the table tennis table cloth textile fabric often occur, which will cause the test results to be closer to the theory. In addition, during the test process, if wrinkles appear on the table tennis table cloth textile fabric sample, it will seriously affect the subsequent test results and need to be adjusted in time. However, during the test, there is no device that can detect whether wrinkles appear on the circular sample of the table tennis table cloth. Moreover, during the test, the standard abrasive is fixed on a smaller fixing seat. Long-term friction is likely to cause cracks to appear at the corners of the standard abrasive and the fixing seat, which will also seriously affect the subsequent test results. There is also no device to detect whether cracks appear at the corners of the standard abrasive and the fixing seat. Therefore, a surface pilling test device and method for table tennis table cloth textile fabric are provided. Summary of the Invention

[0013] A testing method for a device for testing surface fuzzing and pilling of a tablecloth textile fabric comprises the following steps:

[0014] S1. First, the ball table cloth textile fabric samples and standard abrasives;

[0015] S2. Mounting the prepared tablecloth textile fabric sample on a sample holder, and mounting the prepared standard abrasive on a friction holder;

[0016] S3. Select appropriate weights and place them on the pressure threaded rod;

[0017] S4. Start the main body, drive the shaking plate to start moving, and start the test operation;

[0018] S5. During the test, the motor is started to make the gravity ball fall on the tablecloth textile fabric sample to simulate the actual working environment of the tablecloth textile fabric;

[0019] S6. After the test is completed, turn off the motor and the body, remove the rubbed tablecloth textile fabric sample, observe the changes in the tablecloth textile fabric sample, and compare it with the standard pilling sample to complete the pilling rating of the tablecloth textile fabric sample, and then complete the test of the tablecloth textile fabric.

[0020] The beneficial effects of the present invention are:

The gravity ball and the table tennis table fabric will counteract each other, which will simulate the situation when the table tennis table fabric is actually used, thereby improving the accuracy of the test results.

[0022] 2. In addition, during this process, the translation frame will be driven to move back and forth, and the motion trajectories of the first connecting rod and the gravity ball will change, which will eventually cause the landing point of the gravity ball (i.e., the connection point between the gravity ball and the tablecloth textile fabric sample) to continuously change, and ultimately, most of the positions of the tablecloth textile fabric sample can be struck, thereby improving the knocking simulation effect;

[0023] 3. Then, during the above working process, the driven plate is always located on the upper side of the tablecloth textile fabric sample and contacts the tablecloth textile fabric sample. The first pressure sensor sends an electrical signal. If the tablecloth textile fabric sample becomes wrinkled, the driven plate will move upward, thereby causing the electrical signal sent by the first pressure sensor to change, thereby alerting the relevant staff.

[0024] 4. At the same time, the first connecting rod will also cause the gravity ball to rotate. Since there are depressions on both sides of the gravity ball, when the gravity ball and the tablecloth textile fabric sample are against each other, the depressions on the side walls of the gravity ball may be against the tablecloth textile fabric sample, thereby simulating the situation when a broken table ball and the tablecloth textile fabric are against each other, thereby improving the simulation effect;

[0025] 5. Finally, during the test, the right-angle rod is always against the standard abrasive, causing the second pressure sensor to send out a corresponding electrical signal, which will form a detection operation on the edge of the standard abrasive. If the edge of the standard abrasive is damaged, the electrical signal sent by the second pressure sensor will change, which can alert the relevant staff. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] See Figures 1-16 A device for testing the surface fuzzing and pilling of a tablecloth textile fabric comprises a main body 1, a plurality of shock-absorbing plates being fixedly connected to the lower side of the main body 1 to improve the overall stability of the device, a plurality of sample fixing seats 2 being fixedly connected to the upper side of the main body 1, a sample threaded cylinder 6 being threadedly connected to the outer side of each sample fixing seat 2, a shaking plate 3 being further installed on the upper side of the main body 1, a plurality of movable seats 4 being fixedly connected to the upper side of the shaking plate 3, the number and position of the movable seats 4 being opposite to the sample fixing seats 2, a pressure threaded rod 7 being slidably connected to each movable seat 4, a weight 5 being placed on the upper side of the pressure threaded rod 7, a friction fixing seat 8 being fixedly connected to the lower side of the pressure threaded rod 7, and a friction threaded cylinder 9 being threadedly connected to the outer side of the friction fixing seat 8;

[0044] First, a driving assembly for controlling the movement of the shaking plate 3 is installed in the main body 1. The driving assembly includes a working motor, a main shaft, an X-axis cam, a Y-axis cam, a phase adjuster, a lever arm, and a gear set. There are two main shafts, and the ends of the two main shafts are respectively equipped with an X-axis cam and a Y-axis cam. When a test operation is required, the working motor is started, and the working motor drives the main shaft to rotate. Under the action of the gear set, the speed of the Y-axis main shaft is made 2:1 with the speed of the X-axis main shaft. Then the X-axis main shaft rotates through the X-axis cam to push the horizontal lever arm to drive the shaking plate 3 to reciprocate left and right, and the Y-axis main shaft rotates through the Y-axis cam to push the vertical lever arm to drive the shaking plate 3 to reciprocate back and forth. Finally, under the vector superposition of the X-axis simple harmonic vibration and the Y-axis simple harmonic vibration, the motion trajectory of the shaking plate 3 is formed, that is, the Lissajous figure motion trajectory. This technical means is an existing mature technical means. When a test operation is required, first prepare a ball table cloth textile fabric sample and a standard abrasive of appropriate size, and then prepare the ball table cloth textile The fabric sample is installed on the sample fixing seat 2, the prepared standard abrasive is installed on the friction fixing seat 8, the sample threaded cylinder 6 is screwed on the sample fixing seat 2, so that the ball table cloth textile fabric sample is fixed on the sample fixing seat 2, the friction threaded cylinder 9 is screwed on the friction fixing seat 8, so that the standard abrasive is fixed on the friction fixing seat 8, then, a weight 5 of appropriate weight is selected, the weight 5 is placed on the pressure threaded rod 7, the working motor is started, the working motor drives the movable plate 11 to shake, the movable plate 11 drives the movable seat 4, the pressure threaded rod 7 and the friction fixing seat 8 to shake as a whole, and the friction fixing seat 8 drives the standard abrasive to shake, during this process, the standard abrasive is always offset against the ball table cloth textile fabric sample, and the test operation of the ball table cloth textile fabric sample is started, after a period of time, the working motor is turned off, the ball table cloth textile fabric sample after friction is taken out, and the ball table cloth textile fabric sample is compared with the standard pilling sample to complete the pilling rating of the ball table cloth textile fabric sample, and then the test of the ball table cloth textile fabric is completed;

[0045] A simulation component is installed on the upper side of each sample fixing seat 2. The simulation component includes two circular plates 13 slidably installed on the upper side of the sample threaded cylinder 6. The upper sides of the two circular plates 13 are rotatably connected to the moving rod 12. The upper sides of the moving rod 12 are commonly fixedly connected to the moving plate 11. The lower side of the moving plate 11 is fixedly connected to two fixed plates 23. The side walls of the two fixed plates 23 are fixedly connected to fixed rods 37. The outer side of the fixed rod 37 is sleeved with a limit frame 24. A connecting plate 29 is slidably connected in the limit frame 24. The connecting plate 29 is rotatably connected to the first connecting rod 25. The outer side of the first connecting rod 25 is fixedly connected to the gravity ball 15. A power component for controlling the movement of the first connecting rod 25 and the limit frame 24 is installed on the lower side of the moving plate 11. The power component includes a motor 19 fixedly installed on the lower side of the moving plate 11. The outer side of the output shaft of the motor 19 is fixedly connected to a reciprocating wire drum 21, and the outer side of the reciprocating wire drum 21 is threadedly connected to a reciprocating wire ring 26. The outer side of the reciprocating wire ring 26 is fixedly connected to a second connecting rod 28, and the outer side of the second connecting rod 28 is fixedly connected to a moving frame 22. The first connecting rod 25 runs through the moving frame 22. Two positioning plates 20 are symmetrically fixedly connected to the lower side of the moving plate 11. The side walls of the two positioning plates 20 are slidably connected to slide plates 27. The slide plates 27 and the reciprocating wire ring 26 are fixedly connected. The positioning plate 20 is fixedly connected to a translation frame 36 through a telescopic sleeve 34. The translation frame 36 is rotatably connected to the limit frame 24. The side wall of the translation frame 36 is fixedly connected to a first rack 35. Two half gears 33 are fixedly connected to the outer side of the output shaft of the motor 19. The two half gears 33 are respectively meshed with the first rack 35;

[0046] First, the distance between the two circular plates 13 is smaller than the diameter of the sample fixing seat 2. When the ball table cloth textile fabric sample is tested, the pressure threaded rod 7 will shake. When the pressure threaded rod 7 and the movable plate 11 collide with each other, the movable plate 11 will move relative to the sample threaded tube 6. The movement here refers to annular sliding, which is similar to rotation and will not hinder the installation and movement of the friction fixing seat 8. Secondly, during the test, the motor 19 is started. The motor 19 first drives the reciprocating wire tube 21 to rotate. Since the slide plate 27 and the positioning plate 20 on the outside of the reciprocating wire ring 26 are connected to slide up and down, and the reciprocating wire ring 26 and the reciprocating wire tube 21 are threadedly connected, the reciprocating wire ring 26 will move up and down. The reciprocating wire ring 26 drives the movable frame 22 up and down through the second connecting rod 28. The movable frame 22 drives the first connecting rod 25 and the gravity ball 15 to move up and down. In the process of the gravity ball 15 moving up and down, the gravity ball 15 and the ball table cloth textile fabric sample collide with each other. , which will cause the table tennis ball and the table tennis table cloth textile fabric to collide during use. At the same time, the motor 19 drives the half gear 33 to rotate. When the half gear 33 and the first rack 35 are engaged, the half gear 33 drives the first rack 35 to move in the direction close to the motor 19. The first rack 35 drives the translation frame 36 to move in the direction close to the motor 19. The translation frame 36 drives the lower end of the limit frame 24 to deflect. Since the fixed rod 37, the fixed plate 23 and the movable plate 11 are in a fixed state, the limit frame 24 will move along the fixed rod 37, and then the first connecting rod 25 will change the movement trajectory of the first connecting rod 25 and the gravity ball 15 during the up and down movement. Ultimately, the landing point of the gravity ball 15 (that is, the connection point between the gravity ball 15 and the table tennis table cloth textile fabric sample) will continue to change, which can eventually form a knock on most positions of the table tennis table cloth textile fabric sample, thereby improving the knocking simulation effect;

[0047] Furthermore, during the above working process, it should be noted that when the first rack 35 is not engaged with the half gear 33, the angle formed by the limit frame 24 and the translation frame 36 is less than 90 degrees, and even after the first rack 35 is engaged with the half gear 33, when the first rack 35 is just disconnected from the half gear 33 (at this time, the lateral distance between the translation frame 36 and the motor 19 is the smallest), the angle formed by the limit frame 24 and the translation frame 36 is also less than 90 degrees. Therefore, after the half gear 33 and the first rack 35 are disconnected, under the action of the gravity of the gravity ball 15, the translation frame 36 will move away from the motor 19, that is, the translation frame 36 returns to its initial position.

[0048] A detection assembly is installed on the outside of the translation frame 36. The detection assembly includes an active plate 38 that slides through the translation frame 36. A driven plate 39 is slidably connected to the lower side of the active plate 38. A first pressure sensor 42 is fixedly connected between the driven plate 39 and the active plate 38. A first spring 43 is also fixedly connected between the driven plate 39 and the active plate 38. The first spring 43 is a light spring that is easy to deform. A top plate 44 is fixedly connected to the upper side of the translation frame 36. A rotating shaft 45 is rotatably connected to the lower side of the top plate 44. A driven gear 41 is fixedly connected to the outer side of the rotating shaft 45. A second rack 40 is fixedly connected to the upper side of the active plate 38. The second rack 40 is meshed with the driven gear 41, the outer side of the rotating shaft 45 is fixedly connected to a rotating plate 47, the outer side of the translation frame 36 is fixedly connected to a fixed block 49, the side wall of the translation frame 36 is slidably connected to a horizontal plate 48, a second spring 14 is fixedly connected between the horizontal plate 48 and the fixed block 49, the upper side of the horizontal plate 48 is fixedly connected to a vertical plate 46, the outer side of the first connecting rod 25 is fixedly connected to the eccentric rod 32, the eccentric rod 32 and the first connecting rod 25 are in an eccentric state, the outer side of the first connecting rod 25 is fixedly connected to a fixing ring 30, and a first torsion spring 31 is fixedly connected between the fixing ring 30 and the connecting plate 29;

[0049] First, the first pressure sensor 42 is a component that can sense pressure and convert pressure into an electrical signal to transmit to the staff. It is a relatively mature component in real life, so no unnecessary details are given. Secondly, in the process of testing the ball table cloth textile fabric sample, the driven plate 39 is always against the ball table cloth textile fabric sample. Under the obstruction of the ball table cloth textile fabric sample, the first pressure sensor 42 will send out a corresponding electrical signal. In this process, if the ball table cloth textile fabric sample is wrinkled, the driven plate 39 will move upward, which will cause the electrical signal sent by the first pressure sensor 42 to change, thereby alerting the corresponding staff. In addition, in the process of testing the ball table cloth textile fabric sample, the translation frame 36 will move relative to the motor 19. Since the active plate 38 is always slidingly connected to the inner wall of the sample threaded tube 6 The sliding connection here means that an annular groove is opened on the inner wall of the sample threaded barrel 6, and a first connecting slide rod is slidably connected in the annular groove, and an arc groove is opened on the outer side of the active plate 38, and a second connecting slide rod is slidably connected in the arc groove, and a connecting rod is fixedly connected between the second connecting slide rod and the first connecting slide rod). Therefore, during the movement of the translation frame 36, due to the curvature of the sample threaded barrel 6, the driven plate 39 and the active plate 38 will move as a whole relative to the translation frame 36, and the movement direction of the active plate 38 is perpendicular to the movement direction of the translation frame 36. The active plate 38 drives the second rack 40 to move, and the second rack 40 drives the driven gear 41 to rotate. The driven gear 41 drives the rotating shaft 45 and the rotating plate 47 to rotate, and the driven plate 39 moves back and forth all the time, which can expand the overall detection range of the driven plate 39. In this process, when the rotating plate 47 and the cross plate 48 are against each other, Figure 14 From the perspective of , the horizontal plate 48 will move to the right. While the horizontal plate 48 stretches the second spring 14, the horizontal plate 48 drives the vertical plate 46 to move. The vertical plate 46 and the eccentric rod 32 are against each other, so the eccentric rod 32 is squeezed to rotate around the first connecting rod 25. The first connecting rod 25 drives the gravity ball 15 to rotate. Since there are depressions on both sides of the gravity ball 15, when the gravity ball 15 and the table cloth textile fabric sample are against each other, the side wall of the gravity ball 15 may be depressed and against the table cloth textile fabric sample, thereby simulating the situation when a broken billiard ball and the table cloth textile fabric are against each other, thereby improving the simulation effect.

[0050] And it should be noted that, first of all, there are two main reasons for the formation of wrinkles. The first is that there is a gap between the ball table cloth textile fabric sample and the sample threaded cylinder 6 and the sample fixing seat 2, and the contact between the ball table cloth textile fabric sample and the sample threaded cylinder 6 and the sample fixing seat 2 is poor. When the friction operation is performed between the standard abrasive and the table cloth textile fabric sample, the table cloth textile fabric sample is displaced relative to the sample threaded cylinder 6 and the sample fixing seat 2, thereby generating wrinkles. The second is that the quality of the ball table cloth textile fabric sample is extremely poor. Only after a period of time after the friction test operation begins, the ball table cloth textile fabric sample is damaged. In the subsequent friction operation, The ball table cloth textile fabric sample is displaced relative to the sample threaded tube 6 and the sample fixing seat 2, thereby generating wrinkles. Of course, it is also possible that the above two situations occur at the same time. Secondly, the driven plate 39 is a polyvinyl chloride (PVC) foam board, which is light and hard. The driven plate 39 is located on the upper side of the ball table cloth textile fabric sample and is offset against the ball table cloth textile fabric sample. When the ball table cloth textile fabric sample is wrinkled, firstly, the ball table cloth textile fabric sample is thicker than other fabrics, and secondly, the driven plate 39 is lighter. Therefore, when the ball table cloth textile fabric sample is wrinkled, the driven plate 39 will completely move upward.

[0051] A standard abrasive detection assembly is installed on the outside of the friction fixing seat 8. The standard abrasive detection assembly includes a threaded ring 16 threadedly installed on the outside of the pressure threaded rod 7. A rotating ring 10 is rotatably connected to the outside of the threaded ring 16. A second torsion spring is fixedly connected between the rotating ring 10 and the threaded ring 16. A plurality of second pressure sensors 17 are fixedly connected to the lower side of the rotating ring 10. A right-angle rod 18 is fixedly connected to the lower side of the second pressure sensor 17.

[0052] First, the structure, function, and principle of the second pressure sensor 17 are the same as those of the first pressure sensor 42. Second, it should be noted that Figure 2 、 Figure 5 These are schematic diagrams of the device before the tablecloth textile fabric sample is installed. Figure 16After installing the tablecloth textile fabric sample, the connection diagram of the friction fixing seat 8, the gravity ball 15, and the movable plate 11 is shown. Before installing the standard abrasive, the threaded ring 16 is rotated, and the threaded ring 16 drives the rotating ring 10 and the second pressure sensor 17 to move upward as a whole until the right-angle rod 18 and the standard abrasive on the outside of the friction fixing seat 8 just touch each other. Then, during the movement of the friction fixing seat 8 and the pressure threaded rod 7, the movable plate 11 will move, and after starting the motor 19, the gravity ball 15 will move up and down. During the up and down movement, the gravity ball 15 may come into contact with the rotating ring 10, causing the rotating ring 10 to rotate relative to the threaded ring 16, resulting in deformation of the second torsion spring. The rotating ring 10 drives the right-angle rod 18 to rotate, and the right-angle rod 18 always comes into contact with the standard abrasive, causing the second pressure sensor 17 to emit a corresponding electrical signal, thereby detecting the edge of the standard abrasive. If the edge of the standard abrasive is damaged, the electrical signal emitted by the second pressure sensor 17 will change, thereby alerting the relevant staff.

[0053] A testing method for a device for testing surface fuzzing and pilling of a tablecloth textile fabric comprises the following steps:

[0054] S1. First, the ball table cloth textile fabric samples and standard abrasives;

[0055] S2, mounting the prepared tablecloth textile fabric sample on the sample holder 2, and mounting the prepared standard abrasive on the friction holder 8;

[0056] S3. Select a suitable weight 5 and place it on the pressure threaded rod 7;

[0057] S4, start the body 1, drive the shaking plate 3 to start moving, and start the test operation;

[0058] S5. During the test, the motor 19 is started to allow the gravity ball 15 to fall on the ball table cloth textile fabric sample, simulating the actual working environment of the ball table cloth textile fabric;

[0059] S6. After the test is completed, the motor 19 and the body 1 are turned off, the tablecloth textile fabric sample after friction is removed, the changes of the tablecloth textile fabric sample are observed, and compared with the standard pilling sample, the pilling rating of the tablecloth textile fabric sample is completed, and then the test of the tablecloth textile fabric is completed.

[0060] In the present invention, when a test operation is required, first prepare a ball table cloth textile fabric sample and a standard abrasive of appropriate size, then install the prepared ball table cloth textile fabric sample on the sample fixing seat 2, install the prepared standard abrasive on the friction fixing seat 8, screw the sample threaded cylinder 6 on the sample fixing seat 2 to fix the ball table cloth textile fabric sample on the sample fixing seat 2, screw the friction threaded cylinder 9 on the friction fixing seat 8 to fix the standard abrasive on the friction fixing seat 8, then select a weight 5 of appropriate weight, place the weight 5 on the pressure threaded rod 7, start the working motor, and work. The motor drives the movable plate 11 to shake, and the movable plate 11 drives the movable seat 4, the pressure threaded rod 7 and the friction fixed seat 8 to shake as a whole, and the friction fixed seat 8 drives the standard abrasive to shake. During this process, the standard abrasive is always offset against the ball table cloth textile fabric sample, and the ball table cloth textile fabric sample is tested. After a period of time, the working motor is turned off, the ball table cloth textile fabric sample after friction is taken out, and the ball table cloth textile fabric sample is compared with the standard pilling sample to complete the pilling rating of the ball table cloth textile fabric sample, thereby completing the test of the ball table cloth textile fabric;

[0061] During the test, the motor 19 is started. The motor 19 first drives the reciprocating wire drum 21 to rotate. Since the slide plate 27 and the positioning plate 20 on the outside of the reciprocating wire ring 26 are connected by sliding up and down, and the reciprocating wire ring 26 and the reciprocating wire drum 21 are threadedly connected, the reciprocating wire ring 26 will move up and down. The reciprocating wire ring 26 drives the moving frame 22 to move up and down through the second connecting rod 28. The moving frame 22 drives the first connecting rod 25 and the gravity ball 15 to move up and down. In the process of the gravity ball 15 moving up and down, the gravity ball 15 and the ball table cloth textile fabric sample will offset each other, which will cause the table ball and the ball table cloth textile fabric to collide during use. At the same time, the motor 19 drives the half gear 33 to rotate. Between the half gear 33 and the first rack When the first rack 35 is engaged with the first gear 35, the half gear 33 drives the first rack 35 to move in the direction close to the motor 19, and the first rack 35 drives the translation frame 36 to move in the direction close to the motor 19, and the translation frame 36 drives the lower end of the limit frame 24 to deflect. Since the fixed rod 37, the fixed plate 23 and the movable plate 11 are in a fixed state, the limit frame 24 will move along the fixed rod 37, and then the first connecting rod 25 will change the movement trajectory of the first connecting rod 25 and the gravity ball 15 during the up and down movement, and finally the landing point of the gravity ball 15 (that is, the connection point between the gravity ball 15 and the tablecloth textile fabric sample) will change continuously, and finally most of the positions of the tablecloth textile fabric sample can be knocked, thereby improving the knocking simulation effect;

[0062] During the test of the ball table cloth textile fabric sample, the driven plate 39 is always against the ball table cloth textile fabric sample. Under the obstruction of the ball table cloth textile fabric sample, the first pressure sensor 42 will send a corresponding electrical signal. During this process, if the ball table cloth textile fabric sample is wrinkled, the driven plate 39 will move upward, thereby causing the electrical signal sent by the first pressure sensor 42 to change, which can alert the corresponding staff. In the process of testing the ball table cloth textile fabric sample, the translation frame 36 will move relative to the motor 19. Since the active plate 38 is always in sliding connection with the inner wall of the sample threaded tube 6 (the sliding connection here refers to the The inner wall of the cylinder 6 is provided with an annular groove, in which a first connecting slide bar is slidably connected, and an arc groove is provided on the outer side of the active plate 38, in which a second connecting slide bar is slidably connected, and a connecting rod is fixedly connected between the second connecting slide bar and the first connecting slide bar). Therefore, during the movement of the translation frame 36, the driven plate 39 and the active plate 38 will move as a whole relative to the translation frame 36, and the active plate 38 will drive the second rack 40 to move, and the second rack 40 will drive the driven gear 41 to rotate, and the driven gear 41 will drive the rotating shaft 45 and the rotating plate 47 to rotate, and the driven plate 39 will move back and forth all the time, which can expand the detection range of the driven plate 39 as a whole. In this process, when the rotating plate 47 and the cross plate 48 are against each other, Figure 14 From the perspective of , the horizontal plate 48 will move to the right. While the horizontal plate 48 stretches the second spring 14, the horizontal plate 48 drives the vertical plate 46 to move. The vertical plate 46 and the eccentric rod 32 are against each other, so the eccentric rod 32 is squeezed to rotate around the first connecting rod 25. The first connecting rod 25 drives the gravity ball 15 to rotate. Since there are depressions on both sides of the gravity ball 15, when the gravity ball 15 and the table cloth textile fabric sample are against each other, the side wall of the gravity ball 15 may be depressed and against the table cloth textile fabric sample, thereby simulating the situation when a broken billiard ball and the table cloth textile fabric are against each other, thereby improving the simulation effect.

[0063] During the movement of the friction fixing seat 8 and the pressure threaded rod 7, the movable plate 11 will be caused to move, and after starting the motor 19, the gravity ball 15 will be caused to move up and down. During the up and down movement of the gravity ball 15, the gravity ball 15 may be against the rotating ring 10, thereby causing the rotating ring 10 to rotate relative to the threaded ring 16, causing the second torsion spring to deform, and the rotating ring 10 drives the right-angle rod 18 to rotate. The right-angle rod 18 is always against the standard abrasive, thereby causing the second pressure sensor 17 to send a corresponding electrical signal, which will form a detection operation for the edge of the standard abrasive. If the edge of the standard abrasive is damaged, the electrical signal sent by the second pressure sensor 17 will change, thereby alerting the corresponding staff.
