[0028] Also includes:

[0029] The vertical pole 9 is integrally formed and set on the upper end of the support base 2. The front end face of the vertical pole 9 is provided with a water platform 10. The water platform 10 is provided with an inner sliding groove 14. The inner sliding groove 14 is movably provided with a sliding plate 12. The sliding plate 12 is provided with four ball holes 13.

[0030] An embedded wall groove 16 is provided on the inner wall of one side of the inner sliding groove 14, and an electromagnet 17 is fixedly installed inside the embedded wall groove 16 by nail-free adhesive.

[0031] There are two ball-laying frames 4, which are located on both sides of the support base 2. A discharge frame 5 is integrally formed on one outer wall of the ball-laying frame 4.

[0032] The ball groove 3 is located on one side of the electronic scale 7, and the ball groove 3 and the support base 2 are an integral structure.

[0033] In use, if a tennis ball cannot pass through the ball-passing hole, it indicates that the tennis ball does not meet the specifications and has a raised defect on the surface. After the tennis ball passes through the ball-passing hole, it falls into the ball-dropping box. The electronic scale is set to zero in advance. After the tennis ball falls into the ball-dropping box, the electronic scale weighs it. Based on the weight value, it is determined whether the tennis ball has a surface dent defect. Finally, tennis balls that have passed the first two steps of inspection are placed into the ball-rolling trough. The tennis ball is manually pushed to roll, and it is judged whether there is any unevenness in the rolling process, which improves the comprehensiveness of the tennis ball surface inspection.

[0034] Please see Figure 2 and Figure 4 A switch 11 is installed at the upper end of the water platform 10, and a power supply box 15 is installed at the rear end of the vertical pole 9. Both the output and input ends of the switch 11 are equipped with power-on wiring 19. The two power-on wiring 19 are electrically connected to the electromagnet 17 and the power supply box 15, respectively. The switch 11 installed at the upper end of the water platform 10 is used to control the power supply start and stop of the electromagnet 17.

[0035] Please see Figure 2 and Figure 4 The output terminal of the power supply box 15 is electrically connected to the input terminal of the switch 11, and the output terminal of the switch 11 is electrically connected to the input terminal of the electromagnet 17.

[0036] Please see Figure 1A ball discharge groove 6 is provided at the starting end of the discharge frame 5. The discharge frame 5 is connected to the ball release frame 4 through the ball discharge groove 6. The ball discharge groove 6 at the starting end of the discharge frame 5 facilitates the discharge of tennis balls from the discharge frame 5.

[0037] Please see Figure 4 The bottom of the inner sliding groove 14 is provided with an inner through groove 18, which is connected to the ball hole 13. The inner through groove 18 at the bottom of the inner sliding groove 14 facilitates the falling of the tennis ball.

[0038] Please see Figure 4 The movable slide 12 is attached to the water platform 10 by an electromagnet 17.

[0039] Please see Figure 3 The diameters of the four spherical holes 13 increase sequentially.

[0040] Working principle: In use, to test the size of the tennis ball, select one of the four ball-passing holes 13 to test the ball. Push the movable slide plate 12 to move the ball-passing hole 13 directly above the inner through groove 18, and press the switch 11 to power the power box 15 to supply power to the electromagnet 17. The electromagnet 17 generates a magnetic force to attract and fix the movable slide plate 12. Since tennis balls are mostly of different sizes, the selected ball-passing hole 13 is of standard diameter. When the tennis ball cannot pass through the ball-passing hole 13, it indicates that the tennis ball does not meet the specifications and has a protruding defect on the surface. After passing through the ball-passing hole 13, the tennis ball falls into the ball-falling box 8. The electronic scale 7 is set to zero in advance. After the tennis ball falls into the ball box 8, the electronic scale weighs it. Based on the weight value, it is determined whether the tennis ball has surface dents or defects. Finally, the tennis ball that has passed the first two steps of inspection is placed into the ball rolling groove 3. The tennis ball is manually pushed to roll, and it is judged whether there are any irregularities in the rolling process. This improves the comprehensiveness of the tennis ball surface inspection. Finally, the inspected tennis ball is put into the ball placing frame 4. The two ball placing frames 4 are used to separate qualified and unqualified tennis balls. They are discharged through the two discharge frames 5 respectively, completing the use of the surface inspection device for tennis ball production.
