[0025] Specifically, a filter plate 28 is provided inside the placement table 23 corresponding to the suction fan 27 , and a sealing cover is provided at the upper end of the filter plate 28 .

[0026] By adopting the above technical solution, it is possible to prevent a large amount of dust from adhering to the surface of the blades of the suction fan 27 and affecting the adsorption effect during long-term use, thereby ensuring the stability of the equipment.

[0027] Specifically, the positioning device 26 includes a guide groove 261, a pull rod 262, a limit spring 263 and an insert block 264, wherein a guide groove 261 is provided at the inner bottom end of the placement table 23, a pull rod 262 is provided inside the guide groove 261, a limit spring 263 is sleeved on the surface of the pull rod 262, and an insert block 264 is provided at one end of the pull rod 262.

[0028] By adopting the above technical solution, when installing the placement table 23, the pull rod 262 is pulled to drive the plug block 264 to move, and at the same time the limit spring 263 is compressed, and then the placement table 23 is placed on the surface of the slider at the upper end of the moving device 4 and the pull rod 262 is released.

[0030] When a ping-pong ball falls from the ball feeding tube 1, the suction fan 27 is started to perform exhaust work, so that the fallen ping-pong ball falls accurately into the ball placing groove 24 and is stably sucked into the ball placing groove 24 to prevent the fallen ping-pong ball from bouncing up, and when the mobile device 4 drives the placement table 23 to move, the ping-pong ball will not move, thereby ensuring the stability of subsequent hardness detection work, improving detection accuracy, and ensuring work quality.

[0031] Example 2

[0032] The present embodiment is different from the embodiment 1 in that: specifically, the convenient marking component 6 includes a fixed seat 61, an electromagnet 62, a suction block 63, a return spring 64, a mounting bracket 65 and a marking pen 66, wherein a fixed seat 61 is provided at the upper end of the movable plate 9, an electromagnet 62 is provided inside the fixed seat 61, a suction block 63 is provided at the bottom end of the electromagnet 62, a mounting bracket 65 is provided at the bottom end of the suction block 63, a return spring 64 is provided on the surface of the mounting bracket 65, and a marking pen 66 is provided at the bottom end of the mounting bracket 65.

[0033] By adopting the above technical solution, during the detection, the cylinder 8 pushes the movable plate 9 downward so that the sensor 7 contacts the ping-pong ball and continues to detect its force condition. When the sensor 7 is subjected to abnormal force, the electromagnet 62 inside the fixed seat 61 is powered off and no longer attracts the suction block 63. At this time, the reset spring 64 resets and pushes the marker 66 downward to mark the surface of the placement table 23, so that the staff can quickly identify the problem ball for processing. After moving downward for two seconds, the electromagnet 62 is powered on again to attract the suction block 63, so that the marker 66 rises again to prevent obstruction and interference to the moving placement table 23, thereby improving the convenience of equipment use and ensuring work quality.

[0034] Specifically, the mounting frame 65 is configured as a T-shaped frame, and a movable groove is provided inside the fixing seat 61 corresponding to the suction block 63 .

[0036] When this embodiment is in use: during detection, the cylinder 8 pushes the movable plate 9 downward so that the sensor 7 contacts the ping-pong ball and continues to detect its force condition. When the sensor 7 is subjected to abnormal force, the electromagnet 62 inside the fixed seat 61 is powered off and no longer attracts the suction block 63. At this time, the reset spring 64 resets and pushes the marker 66 downward to mark the surface of the placement table 23, so that the staff can quickly identify the problematic ball for processing. Two seconds after moving downward, the electromagnet 62 is powered on again to attract the suction block 63, so that the marker 66 rises again to prevent obstruction and interference to the moving placement table 23, thereby improving the convenience of equipment use and ensuring work quality.

[0037] The structure and use principle of the ball delivery tube 1, the moving device 4 and the sensor 7 in the utility model have been disclosed in a hardness detection device for table tennis ball production and processing disclosed in Chinese patent application No. 202222663870.X.

[0038] Working principle and use process of the utility model: when the utility model is used, hardness test is required in the process of producing table tennis balls. Before the test, the table tennis balls are first placed in the ball feeding tube 1 for loading, and then the placement table 23 is installed. The pull rod 262 is pulled to drive the insert block 264 to move, and at the same time, the limit spring 263 is compressed. Then, the placement table 23 is placed on the surface of the slider at the upper end of the moving device 4 and the pull rod 262 is released. At this time, the limit spring 263 is reset to allow the insert block 264 to be inserted into the slider to install the placement table 23, thereby improving the convenience of disassembly and assembly of the placement table 23, saving human resources, and reducing installation costs.

[0039] When a ping-pong ball falls from the ball delivery tube 1, the suction fan 27 is started to perform air extraction, so that the dropped ping-pong ball falls accurately into the ball placing groove 24 and is stably attracted to the ball placing groove 24, thereby preventing the dropped ping-pong ball from bouncing up and preventing the ping-pong ball from moving when the mobile device 4 drives the placing table 23 to move, thereby ensuring the stability of subsequent hardness testing work, improving the testing accuracy, and ensuring the work quality;

[0040] During the inspection, the cylinder 8 pushes the movable plate 9 downward so that the sensor 7 contacts the ping-pong ball and continues to detect its force condition. When the sensor 7 is subjected to abnormal force, the electromagnet 62 inside the fixed seat 61 is powered off and no longer attracts the suction block 63. At this time, the reset spring 64 resets and pushes the marking pen 66 downward to mark the surface of the placement table 23, so that the staff can quickly identify the problem ball for processing. After moving downward for two seconds, the electromagnet 62 is powered on again to attract the suction block 63, so that the marking pen 66 rises again to prevent obstruction and interference to the moving placement table 23, thereby improving the convenience of equipment use and ensuring work quality.
