The planetary gear set 3 includes a sun gear 31 mounted on the push card output shaft 22, A plurality of planetary gears 32 circling around and meshing with the sun gear 31, a ring gear 33 meshing around the planetary gears 32 and centered on the axis L, and a planetary gear fixedly mounted on the planetary gears 32 The supporting plate 34 can drive the planet gears 32 to rotate along the ring gear 33 by the sun gear 31. In this embodiment, the planetary gear set 3 includes three planetary gears 32 meshing with the sun gear 31 and the ring gear 33 respectively. When the card output shaft 22 drives the sun gear 31 to rotate clockwise, the sun gear 31 drives the planetary gears 32 to rotate counterclockwise along the ring gear 33, and the planetary gears 32 drives the planetary gear support plate 34 to rotate counterclockwise.

The card pushing arm 4 is mounted on the planetary gear set 3 and one end is fixed on the upper surface of the planetary gear support plate 34, and the other end extends downward into the card pushing track groove 11, and the card pushing arm 4 is supported by the planetary gear set. 3 drives to make the other end of the planetary gear set 3 rotate along the card pushing track groove 11 instead. The lower end surface of the card pushing arm 4 is provided with a first magnetic induction element 41. When the card pushing arm 4 is not pushing cards, the first magnetic induction element 41 is located above the first Hall element 13 and is connected to the first Hall element. When the card pushing arm 4 is driven by the planetary gear support plate 34 to rotate counterclockwise for nearly one revolution and the card is pushed into place, the first magnetic sensor 41 is located above the second Hall element 14 and is connected to the second Hall element 14 Er element 14 is matched.

The upper end surface of the base 1 corresponding to the card raising slot 12 is higher than the upper end surface of the card pushing arm 4, which can block the card pushing arm when the first Hall element 13 and the second Hall element 14 are sensed failure. 4. Prevent the card pushing arm 4 from rotating excessively.

A second magnetic induction element 51 and a third magnetic induction element 52 are provided on one side of the card raising board 5. The raising board 5 has a fixed rotatably connected to the base 1 and located in the raising slot 12 The end 53 and a free end 54 opposite to the fixed end 53 and close to the card-distributing end 112 of the card pushing track slot 11. When the card raising board 5 is lowered into position, the second magnetic induction element 51 is matched with the third Hall element 15, and when the raising plate 5 is raised to position, the third magnetic induction element 52 is in phase with the fourth Hall element 16 match.

The raising group 6 is installed on the base 1 and can drive the raising board 5 to rotate. The raising group 6 includes a raising motor 61, a raising board support block 62, and a raising rocker 63.

The card raising motor 61 is fixed on one side of the raising slot 12 and has a raising output shaft 611 penetrating into the raising slot 12, and the raising board support block 62 is fixed on the lower end surface of the raising board 5 A slide groove 621 and a side wall 622 are provided on one side of the card raising plate support block 62. The card raising rocker arm 63 has a connecting end 631 connected to the card raising output shaft 611, and a connecting end 631 opposite to the card raising output shaft 611. The connecting end 631 is slidably disposed on the bearing 632 of the sliding groove 621. When the card raising rocker arm 63 is driven clockwise by the raising output shaft 611, the bearing 632 will rotate in the sliding groove 621 and drive the raising plate 5 to lower the free end 54 to prevent the The free end 54 of the card-up plate 5 has not fallen due to gravity. When the card-up rocker arm 63 reverses counterclockwise, if the fourth Hall element 16 fails to sense, the rib 622 can stop the card-up rocker arm 63 to prevent the upside-down rocker 63 from being over-reversed.

In order to further understand the operation process of the card loading mechanism of the new fully automatic mahjong machine, it is hereby explained that the state of this embodiment when used is as follows:

Before the mahjong machine's card promotion instruction is issued, the third magnetic induction element 52 on the card promotion board 5 matches the fourth Hall element 16, the free end 54 of the card promotion board 5 is located on the desktop, and the card pushing arm 4 is located above the first Hall element 13 and the first magnetic induction element 41 matches the first Hall element 13.

After the mahjong machine’s instruction to raise the card is issued, the raising output shaft 611 drives the raising rocker 63 to rotate clockwise, the free end 54 of the raising board 5 descends, and the second magnetic induction on the raising board 5 When the piece 51 senses the third Hall element 15, the card raising motor 61 stops, and the free end 54 of the card raising plate 5 is lowered into position.

Then the card pushing motor 2 rotates, driving the card pushing output shaft 22 to drive the sun gear 31 to rotate clockwise, and the sun gear 31 drives the planet gears 32 to rotate counterclockwise along the ring gear 33, and the planet gears 32 drive The planetary gear supporting plate 34 rotates counterclockwise, the card pushing arm 4 rotates counterclockwise with the planetary gear supporting plate 34, the card pushing arm 4 pushes a plurality of mahjong tiles arranged in two layers of upper and lower levels in the card pushing track slot 11 ( (Not shown in the figure) from the card entering end 111 of the card pushing track slot 11, along the card pushing track slot 11, sequentially pass through the card outlet end 112 and the entrance end 121 of the card raising slot 12 and then pass the card raising slot 11. The board 5 is pushed to the desktop. When the first magnetic sensor 41 on the card pushing arm 4 senses the second Hall element 14, the card pushing motor 2 stops rotating, and the card pushing arm 4 stops rotating. After a part of the mahjong tiles are pushed onto the table, the rest is placed diagonally on the top surface of the rising board 5.

Then, the card-raising motor 61 drives the card-raising output shaft 611 to drive the card-raising rocker arm 63 to reverse counterclockwise, so that the free end 54 of the card-raising plate 5 rises. When the third magnetic induction element 52 on the card raising plate 5 senses the fourth Hall element 16, the card raising motor 61 stops rotating, and the free end 54 of the card raising plate 5 rises into position. A part of the mahjong tiles on the top surface of the rising board 5 rises to the table, neatly juxtaposed with another part of the mahjong tiles that were previously pushed to the table.

Then, the card pushing motor 2 continues to rotate, driving the planetary gear set 3 to drive the card pushing arm 4 to rotate counterclockwise. When the first magnetic sensor 41 on the card pushing arm 4 senses the first Hall element 13, the card pushing motor 2 stops rotating, the card pushing arm 4 stops rotating, and the mahjong machine enters the next round of card shuffling cycle. middle.

In summary, in the card loading mechanism of the new automatic mahjong machine, the card pushing track groove 11 is small in size, the card pushing output shaft 22 is provided with the planetary gear set 3, and the card pushing arm 4 is mounted on the planetary gear set 3, the planetary gear set 3 drives the card pushing arm 4 to rotate, which greatly reduces the thrust loss of the card pushing motor 2 while ensuring the miniaturization and thinning of the mahjong machine. At the same time, a plurality of matched magnetic induction parts and Hall elements can be arranged to prevent the motor from being overloaded, extend the service life of the push brand motor 2, and facilitate the realization of fully automatic and precise control, so it can indeed achieve the purpose of new cost.

However, the above are only examples of the present model. When the scope of implementation of the present model cannot be limited by this, all simple equivalent changes and modifications made in accordance with the patent scope of the present model application and the contents of the patent specification still belong to This new patent covers the scope.
