[0034] In order to more clearly understand the above-mentioned purposes, features and advantages of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0036] Example:

[0037] like Figure 1-5 As shown, in this embodiment, a thumbwheel ball loading structure is provided, including a ball collecting mechanism, a thumbwheel member 1, a ball loading mechanism 4 and a driving mechanism 5;

[0038] The ball collecting mechanism has a ball collecting cavity 301, the upper ball mechanism 4 has an upper ball channel 404, the upper ball channel 404 is communicated with the ball collecting cavity 301, the driving end of the driving mechanism 5 is connected to the dial member 1, and the dial member 1 is in the ball collecting cavity 301;

[0039] The dial component 1 is provided with a dial slot 101 and an arch-breaking component 102 . The arch-breaking component 102 is relatively arranged above the dial slot 101 .

[0040] The driving mechanism 5 of the present embodiment drives the dial member 1 to rotate, pushing the table tennis balls in the ball collecting cavity 301 into the upper ball channel 404 one by one, and gradually rising up through the mutual squeezing and pushing of the table tennis balls, and then transporting the table tennis balls to the serving component of the table tennis serving machine, so that the table tennis balls smoothly enter the serving position. At the same time, because the dial member 1 has an arch-breaking member 102, the table tennis balls accumulated in the ball collecting cavity 301 can be broken and stirred, so that the accumulated table tennis balls are dispersed and enter the dial slot 101 in turn, so that they can smoothly enter the upper ball channel 404, so as to achieve the purpose of smooth serving.

[0041] The specific structure of the thumbwheel member 1 of this embodiment is as follows:

[0042] It includes a paddle wheel shaft 103 and a paddle wheel piece 104. The paddle wheel shaft 103 is connected to the driving end of the driving mechanism 5. There are more than two paddle wheel pieces 104, which are evenly distributed on the side of the paddle wheel shaft 103 with the axis of the paddle wheel shaft 103 as the center. A paddle wheel slot 101 is formed between adjacent paddle wheel pieces 104, and a broken arch piece 102 is arranged on the top of the paddle wheel shaft 103.

[0043] At the same time, the arch breaking member 102 is a Y-shaped plate structure, the bottom of the arch breaking member 102 is connected to a dial plate 104, the side of the arch breaking member 102 is connected to the top of the dial shaft 103, and the arch breaking member 102 has a V-shaped notch 1021, which is set in a direction away from the dial shaft 103.

[0044] When the arch-breaking member 102 breaks and stirs the ping-pong balls accumulated in the ball collecting cavity 301 , the protruding tip structure on the top can separate the accumulated ping-pong balls, and the structure of the V-shaped notch 1021 plays a guiding role, so that the dispersed ping-pong balls can flow down along the V-shaped notch 1021 into the dial slot 101 .

[0045] The ball collecting mechanism of this embodiment includes a ball collecting seat 2 and a ball collecting plate 3 . The ball collecting plate 3 is connected to the ball collecting seat 2 , and the ball collecting cavity 301 is disposed in the ball collecting plate 3 .

[0046] Specifically, the ball collecting seat 2 is provided with a ball collecting guide part 201 and a ball collecting mounting part, the ball collecting plate 3 is arranged on the ball collecting mounting part, the ball collecting guide part 201 is arranged on both sides of the ball collecting mounting part, and the guide end of the ball collecting guide part 201 is arranged toward the ball collecting plate 3.

[0047] Specifically, the ball loading mechanism 4 includes a ball lane seat 401, a ball lane cover plate 402 and a ball lane cover 403;

[0048] The ball lane seat 401 has a slot, the ball lane cover plate 402 is connected to the ball lane seat 401 and covers the slot, the ball lane cover plate 402 and the slot form an upper ball channel 404, and the ball lane cover 403 is connected to the bottom of the ball lane cover plate 402;

[0049] The ball collecting cavity 301 has a ball dividing slope 405 communicating with the upper ball channel 404, and the ball lane blocking cover 403 is located above the ball dividing slope 405 and forms a ball dividing channel 407 with the ball dividing slope 405;

[0050] The extension direction of the upper ball channel 404 is perpendicular to the plane where the ball collecting cavity 301 is located.

[0051] In the above structure, according to Figure 3 The ball trajectory shows that, because the extension direction of the ball channel 404 is perpendicular to the plane where the ball collecting cavity 301 is located, the table tennis ball output from the ball loading mechanism 4 can fall into the ball collecting cavity 301 well because the table tennis ball is naturally subjected to vertical downward force under the action of gravity and cooperates with the structure of the ball collecting guide 201, which greatly reduces the phenomenon of the table tennis ball not falling into the ball collecting cavity 301 and causing "catching nothing". At the same time, the ball dividing slope 405 is provided to cooperate with the ball dividing channel 407 formed by the ball lane blocking cover 403 to play a guiding effect, so that the table tennis ball can enter the ball loading channel 404 more smoothly.

[0052] In this embodiment, bolts for connection are provided between the ball lane cover plate 402 and the ball lane seat 401, and magnetic suction parts for connection are provided between the ball lane cover 403 and the ball lane cover plate 402. All of the above are detachable structures, which are convenient for disassembly, assembly and maintenance.

[0053] In this embodiment, a ball cavity 406 is provided at the lower end of the ball track seat 401. The ball cavity 406 is used to connect the ball distribution channel 407 and the upper ball channel 404. The cross section of the ball cavity 406 is semicircular.

[0054] According to the above structure, when the driving mechanism 5 drives the dial member 1 to rotate, the ball distribution channel 407 and the guiding structure of the goal cavity 406 are used to move the table tennis ball like a "snail shell" (refer to Figure 3 and Figure 5The ball is transported to the ball-uptake channel 404 of the ball-serving machine according to the rotation trajectory and the semicircular arc surface of the goal cavity 406 and by reasonably utilizing the space to transport the table tennis ball to the ball-uptake channel 404 of the ball-serving machine.

[0055] The driving mechanism 5 of this embodiment is a driving motor.

[0056] This embodiment also provides a table tennis serving machine, including the above-mentioned thumbwheel ball-loading structure.

[0057] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
