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 detection. Background Art

[0002] Volleyball, volleyball is one of the ball sports 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, it is cut into the shape of a bladder using a press. This step requires precise control of the cutting size 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: Inspect 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 the game and use.

[0003] In the prior art, since the common method for detecting volleyball is to detect the air leakage point of the volleyball by using the water detection method, and the water detection 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 volleyball through the air nozzle or the air leakage point of the volleyball, making the internal structures such as the bladder and carcass damp, thus reducing the air leakage detection effect of the volleyball. Summary of the Invention

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

[0005] The above technical object of the present invention is achieved through the following technical solutions: A multi-station detection device for volleyball air leakage detection, including a detection table, a cleaning bin is arranged on one side of the detection table; an air leakage detection component is arranged on the top surface of the detection table for detecting and troubleshooting air-leaking volleyballs. The air leakage detection component includes: a detection cylinder 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. A number of detection gauzes are fixedly installed between the two limiting rings for detecting the air leakage direction of the volleyball. 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. A inflation needle is fixedly sleeved on the inner circular wall surface of the air charging pipe for inflating the volleyball to detect whether the volleyball leaks air and abnormal inflation. 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.

[0006] By adopting the above technical solution, through the arranged detection gauze, when the staff conducts air leakage detection on the volleyball, first, the limiting ring and the detection gauze 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 gauze is placed inside the detection cylinder. Subsequently, the staff puts the volleyball to be detected inside the detection cylinder, so that the volleyball is in the middle position surrounded by a number 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, which is convenient for inflating the deflated volleyball. At the same time, after the gas in the volleyball is sufficient, if there is an air 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 the deflated volleyball, but also can ensure that the volleyball reaches an appropriate air pressure state. After the gas in 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 gauze. At this time, the staff only needs to observe the floating direction of the detection gauze to easily judge whether there is an air leakage in the volleyball, which is convenient for detecting and troubleshooting the air leakage of the volleyball. During the air leakage detection of the volleyball, by synchronously performing the inflation operation, the pressure level inside the volleyball can be significantly increased. This measure makes the pressure difference between the inside and the outside environment of the volleyball more significant, thus accelerating the escape speed of the air at the tiny leakage point and making it easier to be detected in time.

[0007] 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.

An adjusting disc is disposed on the bottom surface of the mounting plate. A plurality of stabilizing blocks are fixedly installed on the top surface of the adjusting disc. A connecting hole is opened on one side of the stabilizing block. The connecting hole is movably sleeved with the movable column.

[0008] By adopting the above technical solution, after the staff places the volleyball below the adjusting disc, by rotating the first gear, the first gear drives the first L-shaped frame to rotate around the rotating column. Furthermore, 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 disc to move through the movable column. The other two stabilizing blocks on the adjusting disc are restricted by the second trapezoidal column and the third trapezoidal column. At this time, the position of the adjusting disc close to the first trapezoidal column will tilt upward, so that the overall adjusting disc can be tilted. Subsequently, by rotating the first gear in reverse, the first L-shaped frame can drive the first trapezoidal column to reset the adjusting disc. 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 disc in different directions, so as to facilitate the adjustment of the spherical position of the volleyball and detect different positions of the volleyball.

[0009] Preferably, the adsorption component includes: an adsorption frame disposed on the top surface of the detection cylinder. A negative pressure hole is opened on the top surface of the adsorption frame. A plurality of adsorption holes are opened on the inner circumferential wall surface of the adsorption frame. A mounting hole is opened on the top surface of the adjusting disc. A micro negative pressure vacuum pump is fixedly installed on the top surface of the adjusting disc. 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.

[0010] 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 the air leakage of the volleyball.

[0011] Preferably, a plurality of limit posts are fixedly installed on the bottom surface of the mounting plate. An operation pipe is arranged on the outer wall surface of the limit post.

An operation ring is fixedly sleeved on the outer wall surface of the operation pipe.

[0012] By adopting the above technical solution, through the operation rings provided, a plurality of operation rings and operation pipes respectively correspond to the first straight gear, the second straight gear and the third straight gear. By rotating one of the operation rings, the operation pipe can be driven to rotate, thus facilitating the rotation adjustment of the first gear, the second gear and the third gear.

[0013] Preferably, the cleaning assembly includes: a mounting post, which is arranged on the top surface of the cleaning bin. A plurality of support posts are fixedly installed on the outer wall surface of the mounting post. A positioning hole is formed on one side of the support post. A cleaning net cylinder is arranged on one side of the support post. A stabilizing post is fixedly installed on one side of the cleaning net cylinder. The stabilizing post is movably sleeved with the positioning hole. Two fixing rings are movably sleeved inside the cleaning net cylinder. A plurality of cleaning plates are fixedly installed between the two fixing rings. A cleaning brush is fixedly installed on one side of the cleaning plate.

[0014] By adopting the above technical solution, through the cleaning net cylinder provided, the staff can put a plurality of volleyballs into the inside of the cleaning net cylinder and make the volleyballs between the two fixing rings. Then, water is put into the cleaning bin. Then, by rotating the mounting post to drive the support posts and the cleaning net cylinder to rotate, the volleyballs can roll between a plurality of cleaning brushes. At the same time, the cleaning net 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.

[0015] Preferably, a fixing column is fixedly installed on one side of the cleaning net cylinder, a blocking column is arranged on one side of the cleaning net cylinder, a circular through hole is opened on one side of the blocking column, the circular through hole is movably sleeved with the fixing column, and a blocking frame is fixedly installed on the top surface of the cleaning bin.

[0016] 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 net cylinder. When the cleaning net cylinder rotates to the position of the detection table, the blocking column will be blocked by the blocking frame. Then, as the cleaning net cylinder continues to rotate, the blocking column can be moved away from one side of the cleaning net cylinder, so that the staff can remove the volleyball from the inside of the cleaning net cylinder.

[0017] Preferably, two support frames are fixedly installed on the top surface of the cleaning bin, the installation column is movably sleeved with the support frames, a first sprocket is fixedly installed at one end of the installation column, a servo motor is arranged on one side of the cleaning bin, and a second sprocket is fixedly installed at one end of the drive shaft of the servo motor.

[0019] 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.

[0020] 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.

[0021] In summary, the present invention mainly has the following beneficial effects: 1. By the mutual cooperation of the arranged detection table, cleaning bin, detection cylinder, limiting ring, detection gauze, air inflation pump, air inflation tube and inflation needle, the volleyball is located at the middle position surrounded by several detection gauzes. Then, by inserting the inflation needle into the inflation hole of the volleyball, and then the staff uses the air inflation pump. After the air inflation pump operates, it will inflate the volleyball, which is convenient for inflating the deflated volleyball. After the gas in the volleyball is sufficient, if there is an air 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 the collapsed 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 an air leakage point in the volleyball, then the air escaping from the air 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 an air leakage in the volleyball, so as to facilitate the air leakage detection and investigation of the volleyball; 2. 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 escape speed of air at the tiny leakage points and making it easier to detect them in a timely manner. 3. By inflating the volleyball to restore it to its original shape, potential problems such as cracks, depressions, or loose air valves hidden due to air leakage become more obvious, making it easier to discover and diagnose the cracks in the volleyball. This method effectively avoids the drawbacks of the traditional water detection method, such as the difficulty in observing the leakage 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 leakage point, causing 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. 4. By rotating the first gear, the first L-shaped frame, the rotating column, the first trapezoidal column, the movable column, the stabilizing block, the adjusting disc, the second trapezoidal column, the third trapezoidal column, the second L-shaped frame, and the third L-shaped frame in cooperation, the adjusting disc can be tilted in different directions, so as to facilitate the adjustment of the spherical position of the volleyball and detect different positions of the volleyball. 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 pipe and the adsorption holes, thereby sucking the volleyball and facilitating the restriction of the volleyball, making it convenient for the staff to detect the air leakage of the volleyball. 6. By rotating the mounting column to drive the support column and the cleaning net cylinder to rotate, the volleyball can roll between several cleaning brushes. At the same time, the cleaning net cylinder will enter the water inside the cleaning chamber during rotation, so as to facilitate the cleaning of the volleyball and prevent the dirt on the surface of the volleyball from blocking the air leakage holes of the volleyball and affecting the detection effect.

A third gear 19 is fixedly sleeved on the outer circular wall surface of the movable pipe 18. The movable pipe 18 is movably sleeved with the mounting pipe 15. 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. Movable 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. Rotating columns 23 are 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 columns 23 are movably sleeved with the movable holes 24. Movable 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 adjustment disc 26 is arranged on the bottom surface of the mounting plate 10. A plurality of stabilizing blocks 27 are fixedly installed on the top surface of the adjustment disc 26. Connecting holes 28 are opened on one side of the stabilizing blocks 27. The connecting holes 28 are movably sleeved with the movable columns 25; With the set detection gauze 5, 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, which is convenient for inflating 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 is not only convenient for quickly inflating the 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 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, which is convenient for conducting a leak detection and troubleshooting on the volleyball. During the leak detection of the volleyball, 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 time. At the same time, the inflation process also prompts the volleyball to return to its original shape, which makes potential problems such as cracks, depressions or valve looseness hidden due to air leakage become more obvious, making the cracks in the volleyball easier to be discovered and diagnosed. This method effectively avoids the disadvantages existing in the traditional water detection method, such as the difficulty in observing the leak point in time due to small bubbles and slow rising speed.Meanwhile, another problem that may be caused by using water detection 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 disc 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 disc 26 to move through the movable column 25. The other two stabilizing blocks 27 on the adjusting disc 26 are restricted by the second trapezoidal column 21 and the third trapezoidal column 22. At this time, the position of the adjusting disc 26 close to the first trapezoidal column 20 will tilt upward, so that the whole adjusting disc 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 disc 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 disc 26 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.

Then, water is put inside the cleaning bin 2, and then by rotating the mounting post 42 to drive the support posts 43 and the cleaning mesh cylinder 45 to rotate, the volleyballs can roll between a number of cleaning brushes 48. At the same time, the cleaning mesh cylinder 45 will enter the water inside the cleaning bin 2 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. The blocking post 49 can block the cleaning plate 47 to prevent the cleaning plate 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.

[0028] 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 driving shaft of the servo motor 57 is fixedly installed with a second sprocket 55. A chain 56 is meshed and connected to the outer circumferential 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 circumferential 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; By providing the 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 adjustment disc 26 downward, facilitating the insertion of the volleyball into the interior of the detection cylinder 3 for air leakage detection.

[0029] 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. 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 with the top surface of the detection cylinder 3. Subsequently, the detection gauze 5 is placed inside the detection cylinder 3. Then, 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, 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 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 valve looseness hidden due to air 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. Water enters the inside of the volleyball through the leak point, causing 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.

[0030] Through the provided adjusting disc 26, after the staff places the volleyball below the adjusting disc 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 due to 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 disc 26 to move through the movable column 25. The other two stabilizing blocks 27 on the adjusting disc 26 are restricted by the second trapezoidal column 21 and the third trapezoidal column 22. At this time, the position of the adjusting disc 26 close to the first trapezoidal column 20 will tilt upward, so that the overall adjusting disc 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 disc 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 disc 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.

[0031] Through the provided adsorption frame 36, when the volleyball is at the bottom of the adjusting disc 26, the volleyball is made to fit with 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, so that the volleyball can be sucked, facilitating the restriction of the volleyball and convenient for the staff to detect the air leakage of the volleyball.

[0032] 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. Then, water is put into the cleaning chamber 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 in the cleaning chamber 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 scope of the present invention is defined by the appended claims and their equivalents.
