As shown particularly in fig. 8, the cam slot includes a first curved section 75, a second curved section 76, a raised section 77 and a lowered section 78. The first curve section 75 and the second curve section 76 are circumferential curve sections with the center of the axle of the curve wheel 7 as the center, and the circumferential radius of the first curve section 75 is larger than that of the second curve section 76.

In addition, a swing limiting frame 57 is provided on the lower end surface of the card lifting supporting plate 51, a swing groove 58 is provided in the swing limiting frame 57, and a roller is provided on the movable end of the second swing arm 56 and slidably disposed in the swing groove 58. The end close to the hinged end of the card raising tray 51 is a proximal end, and the end far from the hinged end of the card raising tray 51 is a distal end. The swing defining frame 57 has a pressing portion 571 provided at a proximal end portion thereof, the pressing portion forming a lower recess 581 for the swing groove 58. In this technical scheme, the roller on the movable end of the second rocker 56 rolls relatively to the swinging groove 58, so that the accuracy of the cooperation between the movable end of the second rocker 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, both ends of the card raising tray 51 are leveled in a horizontal state. During the process of turning down the card raising tray 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 this process, besides the self gravity action of the card lifting support 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, so as to promote the card lifting support plate 51 to turn downwards, and thus the problem that the card lifting support plate 51 cannot be well docked with the card storage groove 32 due to resistance only under the gravity action can be avoided.
In a further preferred embodiment, a first arc-shaped groove 511 is provided on the lower end surface of the card lifting support plate 51 above the lower recess. The first arc-shaped groove is arranged to increase the space above the lower notch, so that the situation that the card lifting supporting plate 51 cannot be turned down to the lowest position due to insufficient space at the top of the roller is avoided. A second arc-shaped groove 512 is arranged on the lower end surface of the card lifting supporting plate 51 above the distal end part of the swing limiting frame 57, and the arc-shaped curve of the second arc-shaped groove 512 takes the swing axis of the second swing arm 56 as the circle center. The second arc-shaped groove is arranged to avoid errors existing during mechanism assembly, and in the second arc-shaped groove, the supporting height of the idler wheel on the card lifting supporting plate 51 cannot be changed, so that the problem that the card lifting supporting plate 51 is unstable due to small angle errors during mechanism assembly can be avoided.
The operation and 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 card lifting connecting rod 52 rotates relative to the cam groove, so that the card lifting connecting rod 52 swings along the hinged end as the center, the other end of the card lifting connecting rod 52 drives the linkage rod 54 to slide relative to the sliding seat 53, and further drives the double rocker arm part to swing, and the movable end of the second rocker arm 56 in the double rocker arm part abuts against the card lifting supporting plate 51 and drives the card lifting supporting plate 51 to rotate. In the above scheme, one end of the card lifting link 52 is hinged on the bracket, the other end of the card lifting link 52 is movably connected with the linkage rod 54, and the third slider 522 in the middle of the card lifting link 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 card lifting link 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 by only needing smaller curve wheels 7 and cam grooves under the structure, thereby being beneficial to further optimizing the internal space of the mahjong machine. Specifically, when the third slider 522 in the tile-lifting link 52 is positioned opposite the second curved section 76 of the cam slot, the tile-lifting pallet 51 is flush with the table top of the mahjong machine when in the horizontal position. With the third slider 522 in the lift link 52 opposite the first curved segment 75 of the cam slot, the movable end of the lift blade 51 is at the lowermost segment and interfaces with the card slot 32. The movable end of the card raising blade 51 is in the process of being raised or lowered when the third slider 522 in the card raising link 52 is positioned opposite the raised or lowered section 77 or 78 of the cam slot.
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 loading assembly 4 and the card lifting assembly 5 are driven to operate by the same set of drive assemblies. Specifically, the driving assembly comprises 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 the axis of the lower end face of the wheel body of the curve wheel 7 is arranged on the lower end face of the wheel body of the curve wheel 7, and a third sliding block 522 is arranged on a rod body of the card lifting connecting rod 52 and is limited in the cam groove of the curve wheel 7. 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 a cam groove in the curve wheel 7 drives the card lifting connecting rod 52 to swing along the hinged end as the center, so that the card lifting supporting plate 51 is finally rotated; meanwhile, the gear teeth on the curve wheel 7 drive the transmission gear 45 to rotate, and finally the card feeding push head 42 on the movable end part of the card feeding push rod 41 can move along the track of the card storage groove 32. The same group of driving components are adopted for driving operation, so that the number of internal operation mechanisms of the mahjong machine can be reduced, the cost is reduced, and the volume of the mahjong machine can be reduced. However, since the card feeding assembly 4 and the card lifting assembly 5 need to cooperate, the above scheme also needs to limit the structure of the curve wheel 7, which is specifically as follows:
the gear teeth on the curve wheel 7 comprise a first tooth part 71 and a second tooth part 72 which are relatively independent and positioned on the same circumference, and a first notch part 73 and a second notch part 74 are arranged between the first tooth part 71 and the second tooth part 72. The first tooth portion 71, the first notch portion 73, the second tooth portion 72, and the second notch portion 74 sequentially constitute a cycle in the rotation direction of the cam 7 (clockwise direction shown in fig. 7). The circumferential angle α1 of the first tooth portion 71 is greater than the circumferential angle α3 of the second tooth portion 72, and more specifically, two radial tangential lines l are centered on the hinged end of the upper card rocker arm 43 and tangent to the edge of the transmission gear 45; the two radial tangential lines 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 meshed transmission with the first tooth part 71, and the arc-shaped length of the first tooth section 453 is equal to that of the first tooth part 71; the second tooth segment 452 is for meshing transmission with the second tooth portion 72, and the arc-shaped length of the second tooth segment 452 is equal to the arc-shaped length of the second tooth portion 72.
The first tooth 71 is axially opposite to the first curve segment 75, the circumferential angle α1 of the first tooth 71 is smaller than the circumferential angle β1 of the first curve segment 75, the movable end of the card lifting support plate 51 keeps in a butt joint state with the card storage groove 32 when the third slider 522 passes through the first curve segment 75, meanwhile, the first tooth 71 is meshed with the first tooth 453 of the transmission gear 45 for transmission, 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 virtue of the card feeding rocker arm 43; the card lifting pallet 51 must remain stationary throughout the card loading process, so that the first tooth 71 is disposed at a circumferential angle α1 that is smaller than the circumferential angle β1 of the first curved section 75.
The second notch 74 is axially opposite to the lifting section 77, and the circumferential angle α2 of the second notch 74 is greater than the circumferential angle β2 of the lifting section 77. When the third slider 522 passes through the lifting section 77, the movable end of the tile lifting supporting plate 51 is gradually lifted, and at this time, the second notch 74 passes through the transmission gear 45, and the transmission gear 45 does not rotate, so that the position of the tile feeding push head 42 at the outlet end of the tile storage groove 32 is unchanged, and the tile feeding push head stops the tile sliding slope. Therefore, in the above scheme, after the lifting of the card lifting plate 51 is completed, the card pushing head 42 is retracted, so that the circumferential angle α2 of the second notch 74 is set to be greater than the circumferential angle β2 of the lifting section 77.
The second tooth portion 72 is axially opposite to the second curved section 76, and a circumferential angle α3 of the second tooth portion 72 is smaller than a circumferential angle β3 of the second curved section 76. The third slider 522 maintains the card-lifting shoe 51 in a horizontal position as it passes over the second curved section 76. Simultaneously, the second tooth part 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 feeding push head 42 to reset from the outlet end to the inlet end of the card storage groove 32 by the card feeding rocker arm 43.
The first notch 73 is axially opposite to the sinking section 78, and the circumferential angle α4 of the first notch 73 is greater than the circumferential angle β4 of the sinking section 78. When the third slider 522 passes through the sinking section 78, the movable end of the card lifting support plate 51 gradually descends, and at this time, the first notch 73 passes through the transmission gear 45, and the transmission gear 45 does not rotate, so that the card feeding pusher 42 is located at the inlet end of the card storage slot 32, and after the card lifting support plate 51 is required to descend, the card feeding process can be performed, and therefore, the circumferential angle α4 of the first notch 73 is greater than the circumferential angle β4 of the sinking section 78. And further, the rising card supporting plate 51 is in a card bearing state in the rising process, and the rising card supporting plate 51 is in an empty load state in the sinking process, so in order to ensure the stability of the card bearing state, the path of the lifting section 77 is longer than the path of the sinking section 78, so that the lifting process can be slowed down, and the stability of the card bearing state is ensured. Thus, the circumferential angle β2 of the raised section 77 is greater than the circumferential angle β4 of the lowered section 78. Based on the slope card discharging device adopting the same group of driving components to drive and operate the card feeding component 4 and the card lifting component 5, the concrete slope card discharging method comprises the following steps:
step 1: after the mahjong tiles with a specified pier number are pushed to the mahjong tile storage groove 32 by the mahjong tile pushing device 2, the curve wheel 7 is driven to rotate by the driving motor 6; in this step, the third slider 522 swings through the sinking section 78 of the cam slot, the hinged end of the card lifting link 52 is taken as the center, the other end of the card lifting link 52 drives the linkage rod 54 to slide relative to the sliding seat 53 (deviating from the direction of the double rocker arm component), and further drives the double rocker arm component to swing, the movable end of the second rocker arm 56 in the double rocker arm component abuts against the card lifting support plate 51 and drives the card lifting support plate 51 to turn down, and finally the movable end of the card lifting support plate 51 is connected with the tail end of the card storage slot 32; in the process, the first notch 73 passes through the transmission gear 45, and the transmission gear 45 does not rotate, so that the position of the card feeding pusher 42 at the inlet end of the card storage groove 32 is unchanged;
step 2: the driving motor 6 continuously drives the curve wheel 7 to continuously rotate; in this step, the third slider 522 is positioned without change in the position of the card raising blade 51 as it passes over the first curved section 75 of the cam slot; simultaneously, the first tooth part 71 is meshed with the first tooth part 453 of the transmission gear 45 to drive the transmission gear 45 to rotate, the transmission gear 45 drives the tile feeding rocker arm 43 to swing a certain angle along the hinged end of the tile feeding rocker arm, and the tile feeding push head 42 pushes mahjong tiles onto the tile lifting support plate 51 from the inlet end of the tile storage groove 32;
step 3: the driving motor 6 continuously drives the curve wheel 7 to continuously rotate; in this step, the third slider 522 swings through the lifting section 77 of the cam groove, the hinged end of the card lifting link 52 is taken as the center, the other end of the card lifting link 52 drives the linkage rod 54 to slide relative to the sliding seat 53 (approaching 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 card lifting support plate 51 and drives the card lifting support plate 51 to lift, and finally the card lifting support plate 51 is flush with the table top of the mahjong machine; in the process, the second notch 74 passes through the transmission gear 45, and the transmission gear 45 does not rotate, so that the position of the card feeding push head 42 at the outlet end of the card storage groove 32 is unchanged;
step 4: the driving motor 6 continuously drives the curve wheel 7 to continuously rotate; in this step, the third slider 522 is positioned unchanged in the position of the card raising tray 51 at the second curved section 76 of the cam slot; meanwhile, the second tooth part 72 is meshed with the second tooth section 452 of the transmission gear 45 to drive the transmission gear 45 to rotate, and the transmission gear 45 drives the card feeding rocker arm 43 to swing a certain angle along the hinged end of the card feeding rocker arm, and the card feeding push head 42 is reset from the outlet end to the inlet end of the card storage groove 32.
