The two ends of the first curve section 75 are connected with the two ends of the second curve section 76 through a rising section 77 and a sinking section 78, the rising section 77 and the sinking section 78 are transition curve sections for connecting two circumferential curves with different radiuses, and the distance between any point of the transition curve section and the center point of the wheel axle of the curve wheel 7 is smaller than the radius of the first curve section 75 and larger than the radius of the second curve section 76.

In addition, a swing limiting frame 57 is arranged on the lower end face of the card lifting supporting plate 51, a swing groove 58 is arranged in the swing limiting frame 57, and a roller is arranged on the movable end of the second swing arm 56 and is arranged in the swing groove 58 in a sliding mode. The end close to the hinged end of the card lifting support plate 51 is a near end part, and the end far away from the hinged end of the card lifting support plate 51 is a far end part. A pressing portion 571 is provided on a proximal end portion of the swing restricting frame 57, and forms a lower notch 581 for the swing groove 58. In this technical solution, the roller on the movable end of the second swing arm 56 rolls relative to the swing groove 58, so that the matching accuracy between the movable end of the second swing arm 56 and the card lifting support plate 51 can be limited. When the roller on the movable end of the second swing arm 56 is at the distal end of the swing groove 58, the two ends of the card raising support plate 51 are leveled and are in a horizontal state. During the turning down of the card raising blade 51, the roller on the movable end of the second swing arm 56 moves from the distal end portion to the proximal end portion of the swing groove 58. In the process, besides the self gravity action of the card lifting supporting plate 51, the roller on the movable end of the second rocker arm 56 can enter the lower notch to press the swing limiting frame 57 downwards to promote the card lifting supporting plate 51 to turn downwards, so that the problem that the card lifting supporting plate 51 cannot be well butted with the card storage groove 32 due to the fact that the card lifting supporting plate is blocked under the gravity action only can be avoided.

In a further preferable scheme, a first arc-shaped groove 511 is arranged on the lower end surface of the card raising supporting plate 51 above the lower notch. The first arc-shaped groove is arranged to increase the space above the lower notch, so that the situation that the tile lifting supporting plate 51 cannot be turned down to the lowest position due to insufficient top space of the roller is avoided. A second arc-shaped groove 512 is arranged on the lower end face of the tile lifting supporting plate 51 above the far end part of the swing limiting frame 57, and the arc-shaped curve of the second arc-shaped groove 512 takes the swing axle center of the second swing arm 56 as the circle center. The second arc-shaped groove is arranged to avoid errors existing in the process of mechanism rotation, and in the second arc-shaped groove, the roller cannot change the supporting height of the tile lifting supporting plate 51, so that the problem that the tile lifting supporting plate 51 is unstable due to small-angle errors in the process of mechanism assembly can be avoided.

The operation transmission process of the card lifting assembly 5 is as follows: the driving motor 6 drives the curve wheel 7 to rotate, the third sliding block 522 in the tile lifting connecting rod 52 rotates relative to the cam groove, so that the tile lifting connecting rod 52 swings around the hinged end of the tile lifting connecting rod as a center, the other end of the tile lifting connecting rod 52 drives the linkage rod 54 to slide relative to the sliding seat 53 and further drives the double-rocker-arm component to swing, and the movable end of the second rocker arm 56 in the double-rocker-arm component abuts against the tile lifting supporting plate 51 and drives the tile lifting supporting plate 51 to rotate. In the above scheme, one end of the tile lifting connecting rod 52 is hinged to the bracket, the other end of the tile lifting connecting rod 52 is movably connected with the linkage rod 54, and the third sliding block 522 in the middle of the tile lifting connecting rod 52 is matched with the cam groove, so that the swing path defined by the cam groove can be enlarged on the movable end of the tile lifting connecting rod 52, and the movement of the linkage rod 54 is realized. Therefore, the lifting requirement of the tile lifting supporting plate 51 can be met only by the small curve wheel 7 and the small cam groove under the structure, and further optimization of the internal space of the mahjong machine is facilitated. Specifically, when the third slide 522 of the card lifting link 52 is located opposite the second curved section 76 of the cam slot, the card lifting blade 51 is flush with the mahjong table when in the horizontal position. When the third slide 522 of the card raising link 52 is located at the first curved section 75 of the cam groove, the movable end of the card raising support plate 51 is at the lowest stage and abuts against the card storage groove 32. When the third slide block 522 of the card lifting link 52 is relatively positioned at the lifting section 77 or the sinking section 78 of the cam groove, the movable end of the card lifting support plate 51 is in the process of lifting or descending.

In the above embodiment, the card feeding assembly 4 and the card lifting assembly 5 are driven to operate by independent driving assemblies respectively. In another embodiment, the card feeding assembly 4 and the card lifting assembly 5 are driven by the same set of driving assemblies. Specifically, the driving assembly includes a driving motor 6 and a curve wheel 7 connected to an output shaft of the driving motor 6, wherein a cam groove circumferentially arranged along an axis of the cam wheel 7 is disposed on a lower end surface of a wheel body of the curve wheel 7, and a third slider 522 disposed on a rod body of the tile lifting link 52 is limited in the cam groove of the curve wheel 7. And the side surface of the wheel body of the curve wheel 7 is provided with gear teeth meshed with the transmission gear 45. The driving motor 6 drives the curve wheel 7 to rotate, and the cam groove in the curve wheel 7 drives the tile lifting connecting rod 52 to swing around the hinged end of the cam groove, so that the tile lifting supporting plate 51 rotates finally; meanwhile, the gear teeth on the curved wheel 7 drive the transmission gear 45 to rotate, and finally the card feeding pushing head 42 on the movable end part of the card feeding pushing rod 41 can move along the track of the card storage groove 32. The same group of driving components are adopted for driving operation, the number of operating mechanisms inside the mahjong machine can be reduced, the cost is reduced, and the size of the mahjong machine can be reduced. However, since the card-loading assembly 4 and the card-lifting assembly 5 need to cooperate, the above solution also needs to define the structure of the curved wheel 7, which is as follows:

the gear teeth on the curve wheel 7 include a first tooth portion 71 and a second tooth portion 72 which are relatively independent and located on the same circumferential line, and a first notch portion 73 and a second notch portion 74 are provided between the first tooth portion 71 and the second tooth portion 72. The first tooth portion 71, the first notch portion 73, the second tooth portion 72, and the second notch portion 74 sequentially form a loop in the rotation direction of the curve wheel 7 (clockwise direction in fig. 7). The circumferential angle of the first tooth part 71 is greater than that of the second tooth part 72, and more specifically, two radial tangent lines l are tangential to the edge of the transmission gear 45 and take the hinged end of the mahjong tile rocker arm 43 as the center of a circle; the two radial tangents divide the tooth part of the transmission gear 45 into a first tooth section 453 with a circle center angle larger than 180 degrees and a second tooth section 452 with a circle center angle smaller than 180 degrees, the first tooth section 453 is used for being meshed with the first tooth part 71 for transmission, and the arc length of the first tooth section 453 is equal to that of the first tooth part 71; the second tooth section 452 is for meshing engagement with the second tooth portion 72, and the arc length of the second tooth section 452 is equal to the arc length of the second tooth portion 72.

The first tooth part 71 is axially opposite to the first curve section 75, the circumferential angle alpha 1 of the first tooth part 71 is smaller than the circumferential angle beta 1 of the first curve section 75, when the third slide block 522 passes through the first curve section 75, the movable end of the card lifting support plate 51 keeps in a butt joint state with the card storage groove 32, meanwhile, the first tooth part 71 is in meshing transmission with the first tooth section 453 of the transmission gear 45, the transmission gear 45 rotates and drives the card feeding push head 42 to be pushed to the outlet end from the inlet end of the card storage groove 32 by means of the card feeding rocker arm 43; the card lifting support plate 51 must be kept stationary during the whole card loading process, so that the circumferential angle α 1 of the first tooth portion 71 is smaller than the circumferential angle β 1 of the first curve segment 75.

The second notch portion 74 is axially opposite to the lifting section 77, and the circumferential angle α 2 of the second notch portion 74 is greater than the circumferential angle β 2 of the lifting section 77. When the third sliding block 522 passes through the lifting section 77, the movable end of the card lifting supporting plate 51 is gradually lifted, at this time, the second notch part 74 passes through the transmission gear 45, the transmission gear 45 does not rotate, so that the position of the card feeding pushing head 42 at the outlet end of the card storage groove 32 is unchanged, and the card feeding pushing head blocks the mahjong cards from sliding down the slope. Therefore, in the above scheme, after the card lifting supporting plate 51 is lifted, the card pushing head 42 is retracted, and therefore the circumferential angle α 2 of the second notch 74 is larger than the circumferential angle β 2 of the lifting section 77.

The second tooth portion 72 is axially opposite to the second curved section 76, and the circumferential angle α 3 of the second tooth portion 72 is smaller than the circumferential angle β 3 of the second curved section 76. The third slider 522 maintains the card lifting blade 51 in a horizontal position as it passes through the second curved section 76. Meanwhile, the second tooth portion 72 is meshed with the second tooth section 452 of the transmission gear 45 for transmission, and the transmission gear 45 rotates and drives the card pushing head 42 to return from the outlet end to the inlet end of the card storage slot 32 by means of the card pushing rocker arm 43.

The first notch portion 73 is axially opposite to the sinking segment 78, and the circumferential angle α 4 of the first notch portion 73 is greater than the circumferential angle β 4 of the sinking segment 78. When the third sliding block 522 passes through the sinking section 78, the movable end of the card lifting supporting plate 51 gradually descends, at this time, the first notch portion 73 passes through the transmission gear 45, the transmission gear 45 does not rotate, so that the position of the card feeding pushing head 42 at the inlet end of the card storage slot 32 is unchanged, and the card feeding process can be performed only after the card lifting supporting plate 51 descends, so that the circumferential angle α 4 of the first notch portion 73 is larger than the circumferential angle β 4 of the sinking section 78. And further, the card raising supporting plate 51 is in a card holding state during the raising process, and the card raising supporting plate 51 is in an idle state during the sinking process, so in order to ensure the stability of the card holding state, it is preferable that the path of the raising section 77 is longer than that of the sinking section 78, so that the raising process can be slowed down, and the stability of the card holding state can be ensured. The circumferential angle β 2 of the lifting section 77 is therefore greater than the circumferential angle β 4 of the sinking section 78.

Based on the slope card-playing device which adopts the same group of driving components to drive the card-feeding component 4 and the card-lifting component 5 to operate, the specific slope card-playing method comprises the following steps:

step 2: the driving motor 6 continues to drive the curve wheel 7 to continue rotating; in this step, the third slider 522 passes through the first curved section 75 of the cam slot, and the position of the card raising support plate 51 is unchanged; meanwhile, the first tooth part 71 is meshed with the first tooth section 453 of the transmission gear 45 for transmission, so that the transmission gear 45 rotates, the transmission gear 45 drives the mahjong tile feeding rocker arm 43 to swing for a certain angle along the hinged end of the transmission gear in the rotating process, and the mahjong tiles are pushed to the tile lifting supporting plate 51 by the mahjong tile feeding pushing head 42 from the inlet end of the tile storage groove 32;

and step 3: the driving motor 6 continues to drive the curve wheel 7 to continue rotating; in this step, the third slider 522 passes through the lifting section 77 of the cam groove, the tile lifting connecting rod 52 swings around the hinged end thereof as the center, the other end of the tile lifting connecting rod 52 drives the linkage rod 54 to slide relative to the sliding seat 53 (close to the direction of the double rocker arm part), and further drives the double rocker arm part to swing, the movable end of the second rocker arm 56 in the double rocker arm part abuts against the tile lifting supporting plate 51 and drives the tile lifting supporting plate 51 to lift, and finally the tile lifting supporting plate 51 is flush with the table top of the mahjong machine; in the process, the second notch part 74 passes through the transmission gear 45, and the transmission gear 45 does not rotate, so that the position of the card feeding pushing head 42 at the outlet end of the card storage groove 32 is unchanged;

and 4, step 4: the driving motor 6 continues to drive the curve wheel 7 to continue rotating; in this step, the third slide 522 is in the second curve section 76 of the cam groove, and the position of the card raising support plate 51 is unchanged; meanwhile, the second tooth part 72 is meshed with the second tooth section 452 of the transmission gear 45 for transmission, so that the transmission gear 45 rotates, the transmission gear 45 drives the mahjong tile feeding rocker arm 43 to swing for a certain angle along the hinged end in the rotating process, and the mahjong tile feeding pushing head 42 is reset from the outlet end to the inlet end of the mahjong tile storage groove 32.
