[0002] Existing mahjong machines are typically equipped with a stacking and pushing mechanism, which is typically equipped with a tile holder, a tile pusher, and a drive motor. The drive motor drives the tile holder to rise and fall, and the tile pusher to push the tiles. The tile holder is located at the card outlet of the loading mechanism. Its operating principle is as follows: when the tile holder is in the upper holding position, a mahjong tile falls from the card outlet of the loading mechanism onto the tile holder. The tile holder then descends to the lower holding position, and another mahjong tile falls onto the previous mahjong tile on the tile holder. The tile pusher then pushes the stack of these two mahjong tiles into the tile raising track slot until all the tiles are pushed into the track slot. During the raising of the tiles, the lifting motor drives the lifting mechanism to push the stack of mahjong tiles in the track slot toward the tabletop.

Therefore, they cannot be understood as limitations on the present invention.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, an integral connection, or a detachable connection; it can be the internal communication of two components; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] A mahjong machine in this embodiment includes four groups Figures 1-10 The rotary card-lifting mechanism shown in the figure includes a card-lifting base 20, a driving mechanism 10, a second swing rod 30 and a card-lifting driving member 40.

[0037] In this embodiment, the structure of the card raising seat 20 is as follows: Figure 6 As shown, it includes a card-lifting seat body 21 and an annular card-lifting groove 22 surrounding the card-lifting seat body 21. The annular card-lifting groove 22 has an inlet side and an outlet side, wherein the inlet side is located at the card outlet position of the card-loading mechanism 50, and the outlet side is connected to the card-lifting plate (not shown in the figure).

[0038] A unique feature of this embodiment is that a receiving area 23 is provided at the entrance of the annular tile-raising trough 22. During shuffling, mahjong tiles fall onto receiving area 23 from the exit of the loading mechanism 50. In this embodiment, a cushioning pad 28 is provided on receiving area 23 to reduce the noise caused by the tiles landing on the receiving area. The cushioning pad can be made of materials including, but not limited to, rubber, silicone, and felt.

[0039] In this embodiment, the main body 21 of the lifting seat is provided with a motor mounting position 24, a first hinge hole 25 and a second hinge hole 27. The first hinge hole 25 and the second hinge hole 27 have a height difference in the height direction, such as Figure 6As shown, a convex portion 26 is provided on the card-lifting seat body 21 , and a second hinge hole 27 is provided on the convex portion 26 .

[0040] As the special feature of this embodiment, Figure 7 As shown, the drive mechanism 10 of this embodiment includes a forward and reversible drive motor 11, a first one-way mechanism 13, a second one-way mechanism 14, a first drive member 15, and a second drive member 16. The first one-way mechanism 13 and the second one-way mechanism 14 are sleeved side by side on the output shaft 12 of the drive motor 11, the first drive member 15 is sleeved on the first one-way mechanism 13, and the second drive member 16 is sleeved on the second one-way mechanism 14.

[0041] The special feature of this embodiment is that the first one-way mechanism 13 and the second one-way mechanism rotate in opposite directions. Thus, when the drive motor 11 rotates in the forward or reverse direction, it can only drive one of the first drive member 15 and the second drive member 16 to rotate. When the direction of the drive motor is switched, the other drive member begins to rotate.

[0042] It should be noted that the first one-way mechanism and the second one-way mechanism both adopt existing mature one-way mechanisms, such as one-way bearings, one-way clutches, one-way ratchet mechanisms, etc. Their specific structures are not limited in this application, and one-way bearings are preferably used.

[0043] As a preferred implementation of this embodiment, Figure 8 As shown, the first driving member 15 of this embodiment is a first rocker arm, which includes a first rocker arm body 152, a connecting seat 151 located at one end of the first rocker arm body 152, and a driving portion 153 located at the other end of the first rocker arm body 152. The connecting seat 151 is sleeved on the first one-way mechanism 13. It should be noted that the shape of the driving portion is not limited and can, for example, be a common columnar structure, a protruding structure, a roller structure, or a rolling bearing.

[0044] Accordingly, the structure of the second swing arm 30 adapted to the first swing arm in this embodiment is as follows: Figure 9 The second rocker arm body 32, the card-pushing head 31 at one end of the second rocker arm body 32, and the hinge column 33 at the other end of the second rocker arm body 32 are shown. The hinge column 33 is rotatably connected to the first hinge hole 25 on the card-lifting seat body. The second rocker arm body is provided with a driving track groove 34 adapted to the driving portion 153. Preferably, the driving track groove 34 is annular, and the second rocker arm is driven by the first rocker arm to swing back and forth around the hinge column. It should be noted that the annular driving track groove is the preferred embodiment of this embodiment, and other track groove shapes that can achieve reciprocating swinging can also be adopted.

[0045] like Figure 1 As shown, in the initial state, the pusher 31 is located on the side of the receiving position 23 away from the annular raising groove. When two mahjong tiles fall onto the receiving position 23 from the card outlet of the card loading mechanism 50, the drive motor 11 is started to drive the first drive member 15 (first swing arm) to rotate, as shown in FIG. Figure 5 As shown, based on the adaptation relationship between the driving portion 153 and the driving track groove 34, the second swing rod 30 is driven to swing around the hinge column 33 to Figure 2 In the state shown, the pusher 31 pushes the stack 60 formed by the two mahjong tiles into the annular lifting groove. At this time, the drive motor 11 continues to rotate in the same direction. Since the driving track groove 34 is annular, the second swing rod 30 is driven to swing in the opposite direction and return to Figure 1 This process is repeated until all mahjong tiles are stored in the circular tile raising slot.

[0046] As a preferred implementation of this embodiment, Figure 4 As shown, the second driving member 16 of this embodiment is a gear, provided with an outer gear ring 161. Accordingly, the driving member for the brand upgrade adapted to the gear is as follows Figure 10 As shown, the card-lifting mechanism comprises a driving body 41, an inner gear ring 42 disposed on the driving body 41, a card-lifting and pushing unit 44, a connecting rod 45 connecting the card-lifting and pushing unit 44 to the driving body 41, and a hinge shaft 43 coaxial with the inner gear ring 42. The inner gear ring 42 meshes with the gear, and the hinge shaft 43 is rotatably connected to the second hinge hole 27 on the card-lifting base body 21. When the drive motor 11 drives the gear (second drive member) to rotate, the card-lifting drive member is driven by the second drive member to rotate about the hinge shaft based on the meshing relationship between the inner gear ring and the gear.

[0047] like Figure 3 As shown, when the shuffling is completed and the tiles need to be raised, the driving motor 11 drives the gear (second driving member) to rotate, and the rotation direction of the driving motor is opposite to the rotation direction when driving the first driving member. The tile raising and pushing unit 44 pushes the mahjong tile stack 60 in the annular tile raising slot out from the exit side, and the tile raising and pushing unit 44 rotates one circle to return to the original position. Figure 1 、 Figure 2 After reaching the position, the drive motor stops rotating.

[0048] In this embodiment, the card lifting and pushing portion 44 and the card pushing head 31 are staggered in the radial direction of the annular card lifting groove. Figure 9 As shown, the card pushing head 31 is provided with an escape groove 35 for accommodating the card lifting and pushing portion 44 to pass through.

[0049] In short, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
