Description

Technical Field

[0001] The present invention relates to the technical field of volleyball detection, and particularly relates to a multi-station detection device for volleyball air leakage troubleshooting. Background Art

[0002] Volleyball, volleyball is one of the ball games that uses both hands to perform actions such as serving, passing, setting, spiking, and blocking to organize offense and defense. The production process of volleyball includes inner bladder production, rubber folding and cutting: natural rubber is selected, after folding treatment, a press is used to cut it into the shape of a bladder. This step requires precise control of the cutting dimensions and shape to ensure that the bladder meets the requirements of subsequent production. Valve installation and inflation: install a valve on the inflation hole of the bladder, and then inflate it to a certain air pressure. The inflated bladder needs to be heated and cured to enhance its stability and durability. Quality inspection, appearance inspection: check the appearance of the volleyball, including aspects such as color, shape, and surface flatness, to ensure that the appearance of the volleyball meets the quality standards. Performance testing: test performance indicators such as the weight, elasticity, and roundness of the volleyball to ensure that the performance of the volleyball meets the requirements of competitions and use.

[0003] In the prior art, since the common detection method for volleyball is to detect the air leakage point of the volleyball by using the water inspection method, and the water inspection method requires putting the volleyball into water. However, when the air leakage at the damaged point of the volleyball is slow or there is only a tiny air leakage, the bubbles generated by the volleyball in the water will be very small and the rising speed will be slow, making it difficult to be accurately observed. Moreover, when the volleyball is soaked in water for a long time, the ball skin will absorb water, which will make the ball skin soft, expand, and may even cause the adhesion force between the ball skin and the internal structure to decrease. At the same time, water will enter the interior of the volleyball through the air nozzle or the air leakage point of the volleyball, causing internal structures such as the bladder and carcass to be affected by moisture, thus reducing the air leakage detection effect of the volleyball. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a multi-station detection device for volleyball air leakage troubleshooting to solve the problems raised in the above background art.

[0005] The above technical objects of the present invention are achieved through the following technical solutions:

[0006] A multi-station detection device for volleyball air leakage detection, including a detection table, on one side of the detection table is provided a cleaning bin; an air leakage detection component, arranged on the top surface of the detection table, used for detecting and troubleshooting air leakage of volleyballs. The air leakage detection component includes: a detection cylinder, the detection cylinder is fixedly installed on the top surface of the detection table, the detection cylinder is made of transparent material, a limiting ring is respectively arranged inside the detection cylinder and on the top surface of the detection cylinder, the two limiting rings are corresponding in position, and a plurality of detection gauzes are fixedly installed between the two limiting rings, used for detecting the air leakage direction of volleyballs. An air pump is fixedly installed on the top surface of the detection table, an air charging pipe is fixedly sleeved outside the air outlet of the air pump, and an inflation needle is fixedly sleeved on the inner circular wall surface of the air charging pipe, used for inflating volleyballs to detect whether the volleyballs leak air and are abnormally inflated. An installation frame is fixedly installed on one side of the detection table; an adjustment component for rotating the volleyball is arranged on the inner top surface of the installation frame; an adsorption component for restricting the volleyball is arranged on the top surface of the detection cylinder; a cleaning component for cleaning the volleyball is arranged on the top surface of the cleaning bin.

[0007] By adopting the above technical solution, through the arranged detection gauzes, when the staff conducts air leakage detection on volleyballs, first, the limiting rings and detection gauzes are placed inside the detection cylinder, and then the limiting ring at the upper end of the detection gauze is left on the top surface of the detection cylinder, so that the bottom surface of the limiting ring contacts the top surface of the detection cylinder, and then the detection gauzes are placed inside the detection cylinder. Subsequently, the staff puts the volleyball to be detected inside the detection cylinder, making the volleyball in the middle position surrounded by a plurality of detection gauzes. Then, the inflation needle is inserted into the inflation hole of the volleyball, and then the staff uses the air pump. After the air pump runs, it will inflate the volleyball, thus facilitating the inflation of deflated volleyballs. At the same time, after the air in the volleyball is sufficient, if there is an air leakage point in the volleyball, the leaked air will blow the detection gauzes. By observing the floating direction of the detection gauzes, this process not only facilitates the rapid inflation of deflated volleyballs, but also ensures that the volleyball reaches an appropriate air pressure state. After the air inside the volleyball is sufficient, if there is an air leakage point in the volleyball, then the air escaping from the air leakage point will blow the surrounding detection gauzes. At this time, the staff only needs to observe the floating direction of the detection gauzes to easily judge whether there is air leakage in the volleyball, thus facilitating the detection and troubleshooting of volleyball air leakage. During the volleyball air leakage detection process, by synchronously performing the inflation operation, the pressure level inside the volleyball can be significantly increased. This measure creates a more significant pressure difference between the inside and outside of the volleyball, thereby accelerating the air escape speed at the tiny leakage points and making it easier to be detected in time.

[0008] Preferably, the adjusting component includes: a mounting plate disposed on the inner top surface of the mounting frame. A rotating column is fixedly installed on the bottom surface of the mounting plate. The bottom surface of the mounting plate is provided with a first L-shaped frame, a second L-shaped frame, and a third L-shaped frame. A first gear is fixedly sleeved on the outer circumferential wall surface of the first L-shaped frame. A mounting tube is fixedly installed on the top surface of the second L-shaped frame. A second gear is fixedly sleeved on the outer circumferential wall surface of the mounting tube. A movable tube is fixedly installed on the top surface of the third L-shaped frame. A third gear is fixedly sleeved on the outer circumferential wall surface of the movable tube. The movable tube is movably sleeved with the mounting tube. The first L-shaped frame is movably sleeved with the mounting tube. A first trapezoidal column is disposed on one side of the first L-shaped frame. A second trapezoidal column is disposed on one side of the second L-shaped frame. A third trapezoidal column is disposed on one side of the third L-shaped frame.

A connecting hole is provided on one side of the stabilizing block. The connecting hole is movably sleeved with the movable column.

[0009] By adopting the above technical solution, after the staff places the volleyball below the adjusting disk, by rotating the first gear, the first gear drives the first L-shaped frame to rotate around the rotating column. Further, the rotation of the first L-shaped frame will drive one end of the first trapezoidal column to move. When the position of one end of the first trapezoidal column changes due to the pulling of the first L-shaped frame, the other end of the first trapezoidal column will pull the stabilizing block and the adjusting disk to move through the movable column. The other two stabilizing blocks on the adjusting disk are restricted by the second trapezoidal column and the third trapezoidal column. At this time, the position of the adjusting disk close to the first trapezoidal column will tilt upward, so that the overall adjusting disk can be tilted. Subsequently, by rotating the first gear back, the first L-shaped frame can drive the first trapezoidal column to reset the adjusting disk. The first L-shaped frame, the second L-shaped frame, and the third L-shaped frame can all perform independent rotational movements to tilt the adjusting disk in different directions, so as to facilitate the adjustment of the spherical position of the volleyball and detect different positions of the volleyball.

[0010] Preferably, the adsorption component includes: an adsorption frame disposed on the top surface of the detection cylinder. A negative pressure hole is provided on the top surface of the adsorption frame. A plurality of adsorption holes are provided on the inner circumferential wall surface of the adsorption frame. A mounting hole is provided on the top surface of the adjusting disk. A micro negative pressure vacuum pump is fixedly installed on the top surface of the adjusting disk. A negative pressure tube is fixedly sleeved on the outer circumferential wall surface of the air extraction port of the micro negative pressure vacuum pump. The negative pressure tube passes through the mounting hole and is fixedly sleeved with the negative pressure hole.

[0011] By adopting the above technical solution, through the adsorption rack provided, when the volleyball is at the bottom of the adjustment plate, the volleyball is made to fit the inner circle of the adsorption rack. Then, by using a micro negative pressure vacuum pump, the negative pressure air generated by the micro negative pressure vacuum pump will be transmitted to the surface of the volleyball through the negative pressure pipe and the adsorption holes, so that the volleyball can be sucked, facilitating the restriction of the volleyball and convenient for the staff to detect air leakage of the volleyball.

[0012] Preferably, a number of limiting columns are fixedly installed on the bottom surface of the mounting plate. An operating pipe is arranged on the outer wall surface of the limiting column. A first spur gear is meshed and connected to the outer wall surface of the first gear. A second spur gear is meshed and connected to the outer wall surface of the mounting pipe.

A bearing is fixedly sleeved on the inner wall surface of the operating pipe. The inner wall surface of the inner ring of the bearing is fixedly sleeved with the limiting column. An operating ring is fixedly sleeved on the outer wall surface of the operating pipe.

[0013] By adopting the above technical solution, through the operating rings provided, a number of operating rings and operating pipes respectively correspond to the first spur gear, the second spur gear and the third spur gear. By rotating one of the operating rings, the operating pipe can be driven to rotate, thus facilitating the rotational adjustment of the first gear, the second gear and the third gear.

[0014] Preferably, the cleaning assembly includes: a mounting column, which is arranged on the top surface of the cleaning bin. A number of support columns are fixedly installed on the outer wall surface of the mounting column. A positioning hole is opened on one side of the support column. A cleaning mesh cylinder is arranged on one side of the support column. A stabilizing column is fixedly installed on one side of the cleaning mesh cylinder. The stabilizing column is movably sleeved in the positioning hole. Two fixing rings are movably sleeved inside the cleaning mesh cylinder. A number of cleaning plates are fixedly installed between the two fixing rings. A cleaning brush is fixedly installed on one side of the cleaning plate.

[0015] By adopting the above technical solution, through the cleaning mesh cylinder provided, the staff can put a number of volleyballs into the inside of the cleaning mesh cylinder and make the volleyballs between the two fixing rings. Then, water is put into the cleaning bin. Then, by rotating the mounting column to drive the support column and the cleaning mesh cylinder to rotate, the volleyballs can roll between a number of cleaning brushes. At the same time, the cleaning mesh cylinder will enter the water inside the cleaning bin during rotation, thus facilitating the cleaning of the volleyballs and preventing the dirt on the surface of the volleyballs from blocking the air leakage holes of the volleyballs and affecting the detection effect.

[0016] Preferably, a fixed column is fixedly installed on one side of the cleaning mesh cylinder, a blocking column is arranged on one side of the cleaning mesh cylinder, a circular through hole is opened on one side of the blocking column, the circular through hole is movably sleeved with the fixed column, and a blocking frame is fixedly installed on the top surface of the cleaning chamber.

[0017] By adopting the above technical solution, through the arranged blocking column, the cleaning plate can be blocked by the blocking column to prevent the cleaning plate from falling out of the inside of the cleaning mesh cylinder. When the cleaning mesh cylinder rotates to the position of the detection table, the blocking column will be blocked by the blocking frame, and then the cleaning mesh cylinder continues to rotate, so that the blocking column can be moved away from one side of the cleaning mesh cylinder, so that the staff can remove the volleyball from the inside of the cleaning mesh cylinder.

[0018] Preferably, two support frames are fixedly installed on the top surface of the cleaning chamber, the mounting column is movably sleeved with the support frames, a first sprocket is fixedly installed at one end of the mounting column, a servo motor is arranged on one side of the cleaning chamber, and a second sprocket is fixedly installed at one end of the driving shaft of the servo motor. A chain is meshed with the outer circumferential wall surfaces of the first sprocket and the second sprocket.

[0020] Preferably, a fixing hole is opened on the top surface of the mounting frame, an electric push rod is fixedly sleeved on the inner circumferential wall surface of the fixing hole, and the telescopic rod of the electric push rod is fixedly installed with the mounting plate.

[0021] By adopting the above technical solution, through the arranged electric push rod, by using the electric push rod, the movement of the telescopic rod of the electric push rod will move the mounting plate and the adjusting disc downward, which is convenient for extending the volleyball into the inside of the detection cylinder for air leakage detection.

[0022] In summary, the present invention mainly has the following beneficial effects:

[0023] 1. By using the detection table, cleaning bin, detection cylinder, limiting ring, detection gauze, air pump, air filling tube and inflation needle in cooperation, the volleyball is placed in the middle position surrounded by several pieces of detection gauze. Then, the inflation needle is inserted into the inflation hole of the volleyball, and then the staff uses the air pump. After the air pump runs, it will inflate the volleyball, which is convenient for inflating a deflated volleyball. After the gas in the volleyball is sufficient, if there is a leakage point in the volleyball, the leaked air will blow the detection gauze. By observing the floating direction of the detection gauze, this process is not only convenient for quickly inflating a deflated volleyball, but also can ensure that the volleyball reaches an appropriate air pressure state. After the gas inside the volleyball is sufficient, if there is a leakage point in the volleyball, then the air escaping from the leakage point will blow the surrounding detection gauze. At this time, the staff only needs to observe the floating direction of the detection gauze to easily judge whether there is a leakage in the volleyball, so as to facilitate the leakage detection and troubleshooting of the volleyball;

[0024] 2. During the volleyball leakage detection process, by synchronously performing the inflation operation, the pressure level inside the volleyball can be significantly increased. This measure creates a more significant pressure difference between the inside and outside of the volleyball, thus accelerating the escape speed of air at the tiny leakage points and making it easier to be detected in a timely manner;

[0025] 3. By inflating the volleyball to make it return to its original shape, potential problems such as cracks, depressions or valve looseness hidden due to leakage become more obvious, making it easier to detect and diagnose the cracks in the volleyball. This method effectively avoids the drawbacks in the traditional water detection method, such as the small bubbles and slow rising speed, which make it difficult to observe the leakage point in a timely manner. At the same time, it also prevents another problem that may be caused by using water detection, that is, water enters the inside of the volleyball through the leakage point, causing the key structures such as the inner bladder and carcass inside to be affected by moisture, thereby reducing the bonding force of the internal structure of the volleyball and affecting the overall performance and service life of the volleyball;

[0026] 4. By rotating the first gear, first L-shaped frame, rotating column, first trapezoidal column, movable column, stabilizing block, adjusting disk, second trapezoidal column, third trapezoidal column, second L-shaped frame and third L-shaped frame in cooperation, the adjusting disk can be tilted in different directions, so as to facilitate the adjustment of the spherical position of the volleyball, so as to detect different positions of the volleyball;

[0027] 5. By using a micro negative pressure vacuum pump, the negative pressure air generated by the micro negative pressure vacuum pump will be transmitted to the surface of the volleyball through the negative pressure tube and adsorption holes, so that the volleyball can be sucked, which is convenient for restricting the volleyball and convenient for the staff to detect the leakage of the volleyball;

[0028] 6. By rotating the mounting column, the support column and the cleaning drum are driven to rotate, so that the volleyball can roll between several cleaning brushes. At the same time, the cleaning drum will enter the water inside the cleaning chamber during rotation, which is convenient for cleaning the volleyball and preventing the dirt on the surface of the volleyball from blocking the air leakage holes of the volleyball and affecting the detection effect.

The first L-shaped frame 12 is movably sleeved with the mounting pipe 15. A first trapezoidal column 20 is arranged on one side of the first L-shaped frame 12. A second trapezoidal column 21 is arranged on one side of the second L-shaped frame 14. A third trapezoidal column 22 is arranged on one side of the third L-shaped frame 17. Moving holes 24 are respectively opened on one side of the first L-shaped frame 12, the second L-shaped frame 14 and the third L-shaped frame 17. A rotating column 23 is respectively fixedly installed on one side of the first trapezoidal column 20, the second trapezoidal column 21 and the third trapezoidal column 22. The rotating column 23 is movably sleeved with the moving hole 24. Moving columns 25 are respectively fixedly installed on the other side of the first trapezoidal column 20, the second trapezoidal column 21 and the third trapezoidal column 22. An adjusting disc 26 is arranged on the bottom surface of the mounting plate 10. A number of stabilizing blocks 27 are fixedly installed on the top surface of the adjusting disc 26. A connecting hole 28 is opened on one side of the stabilizing block 27. The connecting hole 28 is movably sleeved with the moving column 25;

[0048] With the detection gauze 5 provided, when the staff conducts a leak detection on the volleyball, first, the limiting ring 4 and the detection gauze 5 are placed inside the detection cylinder 3. Then, the limiting ring 4 at the upper end of the detection gauze 5 is left on the top surface of the detection cylinder 3, making the bottom surface of the limiting ring 4 contact the top surface of the detection cylinder 3. After that, the detection gauze 5 is placed inside the detection cylinder 3. Subsequently, the staff places the volleyball to be detected inside the detection cylinder 3, making the volleyball in the middle position surrounded by several detection gauzes 5. Then, by inserting the inflation needle 8 into the inflation hole of the volleyball, and then the staff uses the air pump 6. After the air pump 6 operates, it will inflate the volleyball, thus facilitating the inflation of the deflated volleyball. At the same time, after the gas in the volleyball is sufficient, if there is a leak point in the volleyball, the leaked air will blow the detection gauze 5. By observing the floating direction of the detection gauze 5, this process not only facilitates the rapid inflation of the deflated volleyball but also ensures that the volleyball reaches an appropriate air pressure state. After the gas inside the volleyball is sufficient, if there is a leak point in the volleyball, then the air escaping from the leak point will blow the surrounding detection gauze 5. At this time, the staff only needs to observe the floating direction of the detection gauze 5 to easily judge whether there is a leak in the volleyball, thus facilitating the leak detection and troubleshooting of the volleyball. During the volleyball leak detection process, by simultaneously performing the inflation operation, the pressure level inside the volleyball can be significantly increased. This measure creates a more significant pressure difference between the inside and the outside environment of the volleyball, thereby accelerating the escape speed of the air at the tiny leak points and making it easier to be detected in a timely manner. At the same time, the inflation process also causes the volleyball to return to its original shape, making potential problems such as cracks, depressions, or air valve looseness hidden due to leakage become more obvious, and making the cracks in the volleyball easier to be discovered and diagnosed. This method effectively avoids the drawbacks existing in the traditional water detection method, such as the difficulty in observing the leak point in a timely manner due to small bubbles and slow rising speed.Meanwhile, another problem that may be caused by using water inspection is also prevented. Water enters the inside of the volleyball through the air leakage point, causing the key structures such as the inner bladder and the carcass inside to be affected by moisture, thereby reducing the bonding force of the internal structure of the volleyball and affecting the overall performance and service life of the volleyball. After the staff places the volleyball under the adjusting plate 26 through the provided adjusting plate 26, by rotating the first gear 13, the first gear 13 drives the first L-shaped frame 12 to rotate around the rotating column 11. Furthermore, the rotation of the first L-shaped frame 12 will drive one end of the first trapezoidal column 20 to move. When one end of the first trapezoidal column 20 changes its position under the pulling of the first L-shaped frame 12, the other end of the first trapezoidal column 20 will pull the stabilizing block 27 and the adjusting plate 26 to move through the movable column 25. The other two stabilizing blocks 27 on the adjusting plate 26 are restricted by the second trapezoidal column 21 and the third trapezoidal column 22. At this time, the position of the adjusting plate 26 close to the first trapezoidal column 20 will tilt upward, so that the overall adjusting plate 26 can be tilted. Subsequently, by rotating the first gear 13 back, the first L-shaped frame 12 can drive the first trapezoidal column 20 to reset the adjusting plate 26. The first L-shaped frame 12, the second L-shaped frame 14, and the third L-shaped frame 17 can all perform independent rotational movements, so as to tilt the adjusting plate 26 in different directions, thereby facilitating the adjustment of the spherical position of the volleyball and facilitating the detection of different positions of the volleyball.

[0050] Through the provided adsorption frame 36, after the volleyball is at the bottom of the adjustment plate 26, the volleyball is made to fit the inner circle of the adsorption frame 36. Then, by using the micro negative pressure vacuum pump 40, the negative pressure air generated by the micro negative pressure vacuum pump 40 will be transmitted to the surface of the volleyball through the negative pressure pipe 41 and the adsorption holes 38, thereby sucking the volleyball and facilitating the restriction of the volleyball, making it convenient for the staff to detect air leakage of the volleyball. Through the provided operation ring 35, several operation rings 35 and operation pipes 33 respectively correspond to the first straight gear 29, the second straight gear 30, and the third straight gear 31. By rotating one of the operation rings 35, the operation pipe 33 can be driven to rotate, thus facilitating the rotational adjustment of the first gear 13, the second gear 16, and the third gear 19.

[0051] Reference Figure 1 、 Figure 11 — Figure 16 The cleaning assembly includes a mounting post 42. The mounting post 42 is arranged on the top surface of the cleaning bin 2. A plurality of support posts 43 are fixedly installed on the outer circular wall surface of the mounting post 42. A positioning hole 44 is opened on one side of the support post 43. A cleaning mesh cylinder 45 is arranged on one side of the support post 43. A stabilizing post 53 is fixedly installed on one side of the cleaning mesh cylinder 45. The stabilizing post 53 is movably sleeved in the positioning hole 44. Two fixing rings 46 are movably sleeved inside the cleaning mesh cylinder 45. A plurality of cleaning plates 47 are fixedly installed between the two fixing rings 46. A cleaning brush 48 is fixedly installed on one side of the cleaning plate 47. A fixing post 50 is fixedly installed on one side of the cleaning mesh cylinder 45. A blocking post 49 is arranged on one side of the cleaning mesh cylinder 45. A circular through hole is opened on one side of the blocking post 49. The circular through hole is movably sleeved with the fixing post 50. A blocking frame 51 is fixedly installed on the top surface of the cleaning bin 2;

[0052] Through the provided cleaning mesh cylinder 45, the staff can place multiple volleyballs inside the cleaning mesh cylinder 45 and make the volleyballs between the two fixing rings 46. Then, water is put inside the cleaning bin 2. Subsequently, by rotating the mounting post 42 to drive the support post 43 and the cleaning mesh cylinder 45 to rotate, the volleyballs can roll between several cleaning brushes 48. At the same time, the cleaning mesh cylinder 45 will enter the water inside the cleaning bin 2 during rotation, thereby facilitating the cleaning of the volleyballs and preventing the dirt on the surface of the volleyballs from blocking the air leakage holes of the volleyballs and affecting the detection effect. The blocking post 49 can block the cleaning plates 47 to prevent the cleaning plates 47 from falling out of the inside of the cleaning mesh cylinder 45. When the cleaning mesh cylinder 45 rotates to the position of the detection table 1, the blocking post 49 will be blocked by the blocking frame 51. Then, as the cleaning mesh cylinder 45 continues to rotate, the blocking post 49 can be moved away from one side of the cleaning mesh cylinder 45, so that the staff can remove the volleyballs from the inside of the cleaning mesh cylinder 45.

[0053] Reference Figure 1 、 Figure 2 、 Figure 11 and Figure 12, two support frames 52 are fixedly installed on the top surface of the cleaning bin 2. The mounting column 42 is movably sleeved with the support frame 52. One end of the mounting column 42 is fixedly installed with a first sprocket 54. A servo motor 57 is arranged on one side of the cleaning bin 2. One end of the drive shaft of the servo motor 57 is fixedly installed with a second sprocket 55. A chain 56 is meshed and connected to the outer wall surfaces of the first sprocket 54 and the second sprocket 55. A fixing hole 58 is opened on the top surface of the mounting frame 9. The inner wall surface of the fixing hole 58 is fixedly sleeved with an electric push rod 59. The telescopic rod of the electric push rod 59 is fixedly installed with the mounting plate 10;

[0054] Through the provided electric push rod 59, by using the electric push rod 59, the movement of the telescopic rod of the electric push rod 59 will move the mounting plate 10 and the adjusting disc 26 downward, facilitating the insertion of the volleyball into the interior of the detection cylinder 3 for air leakage detection.

[0055] Working principle: Please refer to Figures 1 - 16As shown, through the provided detection gauze 5, when the staff conducts a leak detection on the volleyball, first, the restraint ring 4 and the detection gauze 5 are placed inside the detection cylinder 3, and then the restraint ring 4 at the upper end of the detection gauze 5 is left on the top surface of the detection cylinder 3, making the bottom surface of the restraint ring 4 contact the top surface of the detection cylinder 3. Then, the detection gauze 5 is placed inside the detection cylinder 3. Subsequently, the staff places the volleyball to be detected inside the detection cylinder 3, making the volleyball located at the middle position surrounded by several detection gauzes 5. Then, the inflation needle 8 is inserted into the inflation hole of the volleyball. Furthermore, the staff uses the air pump 6. After the air pump 6 operates, it will inflate the volleyball, thus facilitating the inflation of the deflated volleyball. At the same time, after the gas in the volleyball is sufficient, if there is a leak point in the volleyball, the leaked air will blow the detection gauze 5. By observing the floating direction of the detection gauze 5, this process not only facilitates the rapid inflation of the deflated volleyball but also ensures that the volleyball reaches an appropriate air pressure state. After the gas inside the volleyball is sufficient, if there is a leak point in the volleyball, then the air escaping from the leak point will blow the surrounding detection gauzes 5. At this time, the staff only needs to observe the floating direction of the detection gauze 5 to easily determine whether there is a leak in the volleyball, thus facilitating the leak detection and troubleshooting of the volleyball. During the volleyball leak detection process, by synchronously performing the inflation operation, the pressure level inside the volleyball can be significantly increased. This measure creates a more significant pressure difference between the inside and the outside environment of the volleyball, thereby accelerating the escape speed of the air at the tiny leak points and making it easier to be detected in a timely manner. At the same time, the inflation process also prompts the volleyball to return to its original shape, making potential problems such as cracks, depressions, or air valve looseness hidden due to leakage more obvious, and making the cracks in the volleyball easier to be discovered and diagnosed. This method effectively avoids the drawbacks existing in the traditional water detection method, such as the difficulty in observing the leak point in a timely manner due to small bubbles and slow rising speed. At the same time, it also prevents another problem that may be caused by using water detection, that is, water enters the inside of the volleyball through the leak point, causing the key structures such as the inner bladder and the carcass inside to be affected by moisture, thereby reducing the bonding force inside the volleyball structure and affecting the overall performance and service life of the volleyball.

[0056] Through the provided adjusting disk 26, after the staff places the volleyball below the adjusting disk 26, by rotating the first gear 13, the first gear 13 drives the first L-shaped frame 12 to rotate around the rotating column 11. Further, the rotation of the first L-shaped frame 12 will drive one end of the first trapezoidal column 20 to move. When one end of the first trapezoidal column 20 changes its position under the pull of the first L-shaped frame 12, the other end of the first trapezoidal column 20 will pull the stabilizing block 27 and the adjusting disk 26 to move through the movable column 25. The other two stabilizing blocks 27 on the adjusting disk 26 are restricted by the second trapezoidal column 21 and the third trapezoidal column 22. At this time, the position of the adjusting disk 26 close to the first trapezoidal column 20 will tilt upward, so that the whole adjusting disk 26 can be tilted. Subsequently, by rotating the first gear 13 in reverse, the first L-shaped frame 12 can drive the first trapezoidal column 20 to reset the adjusting disk 26. The first L-shaped frame 12, the second L-shaped frame 14, and the third L-shaped frame 17 can all rotate independently, so as to tilt the adjusting disk 26 in different directions, thereby facilitating the adjustment of the spherical position of the volleyball and facilitating the detection of different positions of the volleyball.

[0057] Through the provided adsorption frame 36, when the volleyball is at the bottom of the adjusting disk 26, the volleyball is made to fit with the inner circle of the adsorption frame 36. Further, by using the micro negative pressure vacuum pump 40, the negative pressure air generated by the micro negative pressure vacuum pump 40 will be transmitted to the surface of the volleyball through the negative pressure pipe 41 and the adsorption holes 38, so that the volleyball can be sucked, facilitating the restriction of the volleyball and facilitating the staff to detect the air leakage of the volleyball.

[0058] Through the provided cleaning net cylinder 45, the staff can put multiple volleyballs into the interior of the cleaning net cylinder 45 and make the volleyballs located between the two fixed rings 46. Further, water is put into the cleaning bin 2, and then by rotating the mounting column 42 to drive the support column 43 and the cleaning net cylinder 45 to rotate, the volleyballs can roll between several cleaning brushes 48. At the same time, the cleaning net cylinder 45 will enter the water inside the cleaning bin 2 during rotation, thus facilitating the cleaning of the volleyballs and preventing the air leakage holes on the surface of the volleyballs from being blocked by dirt, affecting the detection effect.
