Description

Technical Field

[0001] The utility model belongs to the technical field of detecting air leakage of basketballs, in particular to an air leakage detection device for basketball production. Background Art

[0002] In the prior art, after searching, it was found that the Chinese patent disclosed "CN202021837556.3", and its application number is "A basketball production leakage position detection device". This patent mainly benefits from the second motor, the nozzle, and the toggle roller. When working, the basketball is placed in a liquid storage tank with a nozzle on one side. The second motor drives the fan blade to rotate, so that the detection liquid is located at the bottom of the toggle roller to generate a vortex, and the basketball is attracted into the vortex. The water pump extracts the detection liquid and sprays it on both sides of the basketball through the outlet pipe and the nozzle. When the basketball is attracted into the vortex, the toggle roller contacts the top of the basketball and drives the basketball to move to one side of the receiving rack. When the basketball enters the top of the receiving rack, the electric telescopic rod drives the receiving rack to extend and observe the basketball. The second motor, the nozzle, and the toggle roller are set to make the basketball better contact with the detection liquid. When the detection liquid contacts the basketball, if the basketball is deflated, it will cause bubbles on its surface. The setting of the receiving rack facilitates better lifting of the basketball and better observation of the basketball. The device is simple to operate and has better use effect, greatly improves the speed of basketball detection, and is convenient for batch detection.

[0003] However, the device determines whether the basketball is leaking by observing the bubbling phenomenon on the surface of the basketball. When the air pressure inside the basketball is insufficient, the gas inside the basketball will not be able to leak out from the damaged position, so that when the basketball comes into contact with the detection liquid, no bubbling will occur on the surface or the bubbling phenomenon is not obvious, making it difficult to determine whether the basketball is leaking. At the same time, the basketball is moved during observation due to better contact with the detection liquid, which can easily affect the observation and judgment of the staff, resulting in an increased probability of misjudgment and reduced accuracy of the detection.

Since the third gear 32 and the fourth gear 36 are meshed with each other, the third gear 32 and the fourth gear 36 rotate synchronously. The third gear 32 drives the first rotating shaft 30 to rotate. After the classification block 29 blocks the discharge port of the slide 28, the rotation of the first rotating shaft 30 controls the swing of the classification baffle 31 to separate the leaking basketball from the complete basketball.

An air pressure detection port 8 and an air pressure detector 9 are provided to detect the air pressure inside the sealed box in a sealed state, and a certain amount of air is filled into the basketball. If the basketball leaks, the gas inside the basketball enters the sealed box through the leaking position, and the air pressure inside the sealed box increases, causing the value detected by the air pressure detector 9 to rise. On the contrary, if the basketball is intact, the detected value remains unchanged, thereby realizing accurate and convenient detection of whether the basketball is leaking, without moving the basketball. Combining air pressure detection and dynamic changes of gas in a closed environment, the use of numerical observation can more accurately judge and detect the leakage of the basketball, reduce the influence of external environmental factors on the test results, and improve the accuracy of detection.

[0039] By setting a lifting mechanism, the speed of the two output ends of the double-axis motor 18 is controllable. Under the drive of the double-axis motor 18, the output end of the double-axis motor 18 drives the first gear 19 to rotate. Since the first gear 19 and the second gear 25 are meshed with each other, the first gear 19 and the second gear 25 rotate synchronously. The first gear 19 drives the first pulley 22 to rotate.

The pulley 22 is connected, and the second threaded rod 21 is connected to the second pulley 23, so that the first threaded rod 20 and the second threaded rod 21 rotate synchronously. Since the top block 26 is threadedly connected to the first threaded rod 20 and the second threaded rod 21, the rotation of the first threaded rod 20 and the second threaded rod 21 drives the top block 26 to rise and fall, and the motor drives the top block 26 to rise and fall. The top surface of the top block 26 is inclined to the right, and the inclined surface of the top block 26 is used to lift the basketball in the sealed box, causing the basketball to lose balance and roll into the slide 28 for classification.

Under the cooperation of the third pulley 27, the fourth pulley 33 and the second belt 37, the third pulley 27 rotates synchronously with the fourth pulley 33. When the fourth pulley 33 drives the second rotating shaft 34 to rotate, the fourth gear 36 rotates synchronously with the second rotating shaft 34 fixed on the fixed block 35. The second rotating shaft 34 drives the fourth gear 36 to rotate. Since the third gear 32 and the fourth gear 36 are meshed with each other, the third gear 32 and the fourth gear 36 are meshed with each other. The fourth gear 36 rotates synchronously, and the third gear 32 drives the first rotating shaft 30 to rotate. The classification block 29 blocks the discharge port of the slide 28, so that the classification baffle 31 is swung by the rotation of the first rotating shaft 30 to separate the leaking and complete basketballs. The swing of the classification baffle 31 is controlled by a motor to screen out the leaking basketballs from the complete basketballs, which can more effectively manage the basketball inventory, improve management efficiency and the overall quality management level of the basketballs, and enable the staff to quickly repair the screened leaking basketballs to ensure the quality of the basketballs.
