[0024] refer to Figure 1 ,2 As shown in Figure 3, this utility model provides a novel mahjong machine head, including a machine box 1, a dual-axis push-and-stacking wheel 2, a stacking component 3, and a pushing component 4.
[0025] The interior of the housing 1 is divided into two cavities, front and rear, by a partition 11. The front cavity is the first cavity 12, and the rear cavity is the second cavity 13. The partition 11 is provided with a strip hole 14, which is opened in the vertical direction.
[0026] The dual-axis card-stacking wheel 2 includes a rotating wheel 21, a first pin 21, and a second pin 22. The rotating wheel 21 is rotatably supported within a first cavity 12 via a rotating shaft. The first pin 21 and the second pin 22 are located on the outer side of the rotating wheel 21, distributed on different circumferences. The distance between the axis of the first pin 21 and the central axis of the rotating wheel 21 is greater than the distance between the axis of the second pin 22 and the central axis of the rotating wheel 21, and the length of the second pin 22 is greater than the length of the first pin 21. In this embodiment, the included angle between the centers formed by the first pin 21 and the second pin is 90°.
[0027] The card stacking component 3 is located outside the rotating wheel 21. The card stacking component 3 includes a card stacking body 31 and a card stacking seat 32. One end of the card stacking body 31 is rotatably supported on the inner wall of the first cavity 12, and the other end of the card stacking body 31 passes through the strip hole 14 on the partition plate 11 into the second cavity 13. The card stacking seat 32 is located at the end of the card stacking body 31 located within the second cavity 13. The card stacking body 31 has a card stacking trajectory hole 33. The first pin 21 and the second pin 22 pass through the card stacking trajectory hole 33 and slide in cooperation with the hole wall of the card stacking trajectory hole 33. The dual-axis card stacking wheel 2 is driven to rotate by a drive motor. Through the first pin 21 and the second pin 22, the card stacking body 31 can be driven to swing up and down around its axis, thereby causing the card stacking seat 32 to move up and down within the second cavity 13.
[0028] The card pusher 4 is located outside the card stacking unit 3. The card pusher 4 includes a card pusher body 41 and a card pusher head 42. The card pusher body 41 is located inside the first cavity 12. One end of the card pusher body 41 is rotatably supported on the inner side wall of the first cavity 12. The card pusher head 42 is located at the other end of the card pusher body 41. The card pusher head 42 is located on the upper outer side of the second cavity 13. The card pusher body 41 is provided with a card pusher track hole 43. The second pin 22 passes through the card pusher track hole 43 and slides in fit. As the second pin 22 rotates with the rotating wheel 21, it can drive the card pusher 4 to swing. When the card pusher 4 swings, its card pusher head 42 can slide over the second cavity 13, thereby pushing the stacked cards on the card stacking base 32 into the card storage slot of the mahjong machine table.
[0029] The rear side wall of the second cavity 13 is provided with a sensing hole, and a sensor 5 is provided at the sensing hole. The sensor 5 is used to sense whether the stacking of cards is completed each time. If the stacking of cards is completed, a push card instruction is given.
[0030] The working principle of the novel mahjong machine head provided in this embodiment is as follows:
[0031] During operation, the first mahjong tile enters the stacking base 32, and then the drive motor drives the rotating wheel 21 to rotate. The first pin 21 and the second pin 22 on the rotating wheel 21 cause the stacking body 31 to sink, and at the same time, the stacking base 32 also moves downward to the set position in the second cavity 13. The drive motor stops rotating. At this time, the second mahjong tile is pushed onto the stacking base 32 and stacked on top of the first mahjong tile. Then the drive motor starts working. Under the action of the first pin 21 and the second pin 22, the stacking body 31 drives the stacking base 32 to rise to the set position. Then, under the action of the second pin 22, the pusher body 41 drives the pusher head 42 to push the two stacked mahjong tiles into the storage slot of the mahjong machine. This cycle is repeated until the shuffling is completed.
[0032] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
