[0047] like Figures 1 to 9 As shown in the embodiment of this utility model, the tilting card-feeding device of the automatic mahjong machine includes a card-pushing mechanism 200 and a card-lifting mechanism 100.

[0048] In this embodiment, the tile-pushing mechanism 200 includes a tile-pushing bracket 210, a tile-pushing component 220, and a tile-pushing motor for driving the tile-pushing component 220. The tile-pushing bracket 210 is provided with a tile-pushing groove 215 for storing mahjong tiles. The tile-pushing groove 215 includes a tile inlet 2152 and a tile outlet 2151, and the tile-pushing groove 215 has an arc-shaped curved structure with a bending angle greater than 180° from the tile inlet 2152 to the tile outlet 2151. The tile-pushing component 220 includes a tile-pushing head, which moves in the tile-pushing groove 215 to push the mahjong tiles toward the tile outlet 2151. The tile pusher 210 includes a tile pusher base 211, an outer ring baffle 212, and an inner ring baffle 213. The outer ring baffle 212 and the inner ring baffle 213 are mounted on the tile pusher base 211, and the outer ring baffle 212, the inner ring baffle 213, and the tile pusher base 211 together form a tile pusher groove 215. The outer ring baffle 212 and the inner ring baffle 213 define the movement trajectory of the mahjong tiles in the tile pusher groove 215, and the distance between the outer ring baffle 212 and the inner ring baffle 213 allows the mahjong tiles to move smoothly between them.

[0049] In some other embodiments, the card-pushing mechanism 200 may also be the card-pushing mechanism 200 described in Chinese Utility Model Patent No. CN200966910Y, entitled "Slope Card-Pushing Device for Fully Automatic Mahjong Machine". In this patent, four arc-shaped card-pushing grooves arranged in a windmill shape are provided below the mahjong machine table.

[0050] In the embodiment, the card lifting mechanism 100 is installed on the pushing bracket 210, the card lifting mechanism 100 comprises a card lifting motor 120 and a card lifting plate 110, the pushing bracket 210 further comprises a card lifting plate mounting portion 214, the card lifting plate mounting portion 214 is formed by extending one end of the pushing base 211 in a direction away from the card outlet 2151, the card lifting plate mounting portion 214 has a swing space for the swing lifting of the card lifting plate 110, one end of the card lifting plate 110 is rotationally connected to the card lifting plate mounting portion 214, and the card lifting motor 120 is used to drive the card lifting plate 110 to swing and lift so as to make the other end of the card lifting plate 110 to lift. The card lifting motor 120 is installed at the lower end of the central region of the pushing base 211.

[0051] In the embodiment, the card lifting motor 120 and the pushing motor are independent of each other, the card lifting motor 120 is used to drive the card lifting plate 110 to move, and the pushing motor is used to drive the pushing component 220 to move.

[0052] In the embodiment, the card lifting mechanism 100 further comprises a driving wheel 130, a fork 140 and a card lifting connecting rod 150, the driving wheel 130 is provided with a pushing block 131, the card lifting connecting rod 150 is provided with a protruding block 151, the pushing block 131 pushes the fork 140 to make the fork 140 drive the card lifting connecting rod 150 to move in a first direction, the pushing block 131 pushes the protruding block 151 to make the card lifting connecting rod 150 move in a second direction opposite to the first direction, the rotation of the driving wheel 130 drives the pushing block 131 to alternately push the protruding block 151 and the fork 140, so as to make the card lifting connecting rod 150 reciprocate and drive the card lifting plate 110 to swing and lift. The fork 140 is provided with a pushing rod 141, the pushing block 131 pushes the pushing rod 141 to make the fork 140 move. The fork 140 can be linear motion or rotation.

[0053] The movement of the card lifting connecting rod 150 in the first direction makes the card lifting plate 110 to swing and descend, the swing and descent of the card lifting plate 110 makes one end of the card lifting plate 110 to connect the card outlet 2151 of the pushing groove 215, and the mahjong tile is pushed onto the card lifting plate 110 by the pushing head. The movement of the card lifting connecting rod 150 in the second direction makes the card lifting plate 110 to swing and ascend, and the swing and ascent of the card lifting plate 110 lifts the mahjong tile to the table surface of the automatic mahjong machine.

[0054] The tilting card feeding device of the embodiment can make the card lifting link 150 reciprocate to drive the card lifting plate 110 to swing and lift by the alternate poking of the protrusions 151 on the card lifting link 150 and the fork 140 by the poking block 131 on the driving wheel 130, so that the card lifting mechanism 100 does not need to use a cam with a complex shape, the design of the fork 140 and the protrusion 151 is relatively simple, thereby effectively reducing the design difficulty and production cost of the card lifting mechanism 100 and the tilting card feeding device; at the same time, since the driving wheel 130 pokes the fork 140 intermittently, there is no direct transmission connection relationship between the two, which can avoid transmission loss caused by direct transmission of the two, and more importantly, the arrangement of the driving wheel 130 and the fork 140 makes that there is no alignment installation position relationship between the two, so that there is no need to design the assembly or avoiding structure related to each other between the two, and the two do not need to be aligned during assembly, which further simplifies the design, production and assembly difficulty of the card lifting mechanism 100 and the tilting card feeding device.

[0055] In one embodiment, as shown in Figure 6 、 Figure 8 The card lifting mechanism 100 further comprises a card lifting rocker arm 160, the card lifting rocker arm 160 is rotationally connected to the card pushing support 210, one end of the card lifting rocker arm 160 is connected to the card lifting plate 110, and the other end of the card lifting rocker arm 160 is connected to the card lifting link 150, the movement of the card lifting link 150 drives the card lifting rocker arm 160 to swing to make the card lifting plate 110 swing and lift.

[0056] The transmission connection mode of the card lifting rocker arm 160 with the card lifting plate 110 and the card lifting link 150 can refer to the Chinese utility model patent with the publication number CN209967649U and the name of card storage and lifting device.

[0057] Through the above arrangement, the reciprocating movement of the card lifting link 150 can be converted into the swing and lift of the card lifting plate 110 through the swing of the card lifting rocker arm 160, so as to complete the pushing and lifting of mahjong tiles in cooperation with the card pushing mechanism 200.

[0058] In one embodiment, as shown in Figure 2 、 Figure 5 、 Figure 7 、 Figure 9 The fork 140 is rotationally connected to the card pushing support 210, and the fork 140 is linked with the card lifting link 150 to make the fork 140 swing.

[0059] The movement distance of the card lifting link 150 is determined by the rotation angle of the fork 140 and the length of the force arm between the fork 140 and the card lifting link 150, so that the parameters of the fork 140 can be reasonably designed and adjusted according to actual needs to meet the needs of different tilting card feeding devices.

[0060] Compared with the mode that the straight-line motion of the fork 140 drives the card lifting link 150, the fork 140 is rotationally connected to the card pushing support 210, and the motion of the fork 140 does not need to be guided through a guide mechanism, thereby saving the corresponding cost; and the fork 140 swings in linkage with the card lifting link 150, so that the fork 140 can drive the card lifting link 150 to move, and the reverse motion of the card lifting link 150 can push the fork 140 to reset, thereby eliminating the need to design a reset device for the fork 140, and further simplifying the design difficulty and cost of the card lifting mechanism 100.

[0061] In one embodiment, as shown in Figures 2 to 5 、 Figure 7 、 Figure 9 , the fork 140 is provided with a first transmission member 142, and the card lifting link 150 is provided with a second transmission member 154, and the first transmission member 142 is transmissionally and slidingly connected to the second transmission member 154.

[0062] Since the fork 140 swings, the motion direction of the card lifting link 150 is not completely consistent with that of the fork 140, so that the straight-line distance between the first transmission member 142 and the second transmission member 154 changes with the swinging motion of the fork 140, and the transmissionally sliding connection between the first transmission member 142 and the second transmission member 154 enables them to be transmissionally connected while changing the connection position, thereby avoiding the transmission connection failure of the two members due to the change of the straight-line distance between them, and ensuring the effective transmission between the fork 140 and the card lifting link 150.

[0063] In one embodiment, as shown in Figure 3 、 Figure 5 、 Figure 7 、 Figure 9 , the first transmission member 142 is a transmission groove, and the second transmission member 154 is a transmission pin, and the transmission pin is slidingly connected in the transmission groove.

[0064] Specifically, the card lifting link 150 is provided with a base 153 protruding toward the fork 140, and the transmission pin is connected to the base 153. The length of the transmission groove is greater than the diameter of the transmission pin, so that the transmission pin can slide in the transmission groove. The swinging motion of the fork 140 causes the groove wall of the transmission groove to act on the transmission pin and drive the card lifting link 150 to move, and the reset motion of the card lifting link 150 causes the transmission pin to act on the groove wall of the transmission groove and drive the fork 140 to reset.

[0065] In other embodiments, the first transmission member 142 can also be a transmission pin, and the second transmission member 154 can also be a transmission groove.

[0066] In this way, the first transmission member 142 and the second transmission member 154 can be kept in transmission connection within the swing movement range of the shifting fork 140, which helps to improve the movement response speed of the card lifting link 150 when the card lifting plate 110 is switched to be lifted or lowered.

[0067] In another embodiment, the first transmission member 142 and the second transmission member 154 can also be a combination of a transmission pin and a transmission rod.

[0068] Specifically, one of the first transmission member 142 and the second transmission member 154 is a transmission rod, and the other is a transmission pin abutting on the transmission rod. The swing movement of the shifting fork 140 and the linear movement of the card lifting link 150 make the transmission pin slide between the two ends of the transmission rod with a force, so that the first transmission member 142 and the second transmission member 154 are kept in sliding connection during the movement of the card lifting link 150.

[0069] Through the cooperation of the transmission rod and the transmission pin, the transmission structure between the shifting fork 140 and the card lifting link 150 is simpler, which helps to reduce the cost.

[0070] In one embodiment, as shown in Figures 2 to 4 , Figure 7 , Figure 9 The lifting block 131 is provided with a positioning convex arc surface 132, and the convex block 151 is provided with a positioning concave arc surface 152. The positioning convex arc surface 132 and the positioning concave arc surface 152 are in concave-convex cooperation to lock the card lifting link 150.

[0071] The concave-convex cooperation of the positioning convex arc surface 132 and the positioning concave arc surface 152 means that the two arc surfaces are concentric. When the lifting block 131 drives the convex block 151 to move in the second direction, the positioning convex arc surface 132 and the positioning concave arc surface 152 are in concave-convex cooperation. When the card lifting link 150 moves to the terminal position of card lifting, the lifting block 131 can slide relative to the convex block 151 without driving the convex block 151 to move, thereby limiting the continuous movement of the card lifting link 150. At the same time, the concave-convex cooperation of the positioning convex arc surface 132 and the positioning concave arc surface 152 makes the positioning convex arc surface 132 block on the positioning concave arc surface 152, thereby limiting the movement of the card lifting link 150 to the first direction. Since the card lifting plate 110 has mahjong tiles stacked thereon, the card lifting plate 110 has a tendency to swing downward, but the card lifting link 150 is limited to move, so that the card lifting link 150 limits the movement of the card lifting plate 110, and the card lifting plate 110 is locked in the card lifting state.

[0072] In the concave-convex cooperation between the positioning convex arc surface 132 and the positioning concave arc surface 152, a gap is not provided between the two, but due to the machining precision and assembly error, the positioning convex arc surface 132 and the positioning concave arc surface 152 are inevitably provided with a gap in at least part of the positions. Although this part of the gap can cause slight displacement or shaking of the positioning concave arc surface 152 relative to the positioning convex arc surface 132, the displacement or shaking does not affect the concave-convex cooperation between the positioning convex arc surface 132 and the positioning concave arc surface 152 to lock the raised tile plate 110 in the raised tile state, or has little effect on the raised tile plate 110 locked in the raised tile state.

[0073] The concave-convex cooperation between the positioning convex arc surface 132 on the dial block 131 and the positioning concave arc surface 152 on the convex block 151 locks the raised tile plate 110 in the raised tile state, avoids the raised tile plate 110 from descending due to the gravity of the mahjong tiles in the raised tile state, and enables the raised tile plate 110 to stably support the mahjong tiles, thereby improving the reliability and stability of the raised tile mechanism 100.

[0074] In one embodiment, as shown in Figure 5 , Figure 6 , Figure 8 The raised tile mechanism 100 further includes a first sensor 171, and the dial fork 140 is provided with a sensing unit. The first sensor 171 detects the raised tile termination position of the raised tile connecting rod 150, and the first sensor 171 is triggered by the sensing unit in the concave-convex cooperation process between the positioning convex arc surface 132 and the positioning concave arc surface 152.

[0075] When the first sensor 171 is triggered by the sensing unit, the raised tile motor 120 stops rotating, so that the raised tile plate 110 is kept in the raised tile state, and due to the concave-convex cooperation between the positioning convex arc surface 132 and the positioning concave arc surface 152, the raised tile plate 110 can be stably maintained in the raised tile state.

[0076] In this embodiment, the first sensor 171 is a Hall element, and the sensing unit is a magnetic piece. Referring to Figure 5 , the dial fork 140 is provided with a mounting hole 143 for mounting the sensing unit.

[0077] In other embodiments, the first sensor 171 can also be a photoelectric sensor, and the sensing unit is a through hole provided on the dial fork 140.

[0078] By providing the first sensor 171, the raised tile plate 110 stops the raised tile motor 120 after lifting the mahjong tiles onto the table surface of the automatic mahjong machine, and at the same time, the first sensor 171 is triggered in the concave-convex cooperation process between the positioning convex arc surface 132 and the positioning concave arc surface 152, so that the raised tile plate 110 can be locked in the raised tile state, avoiding the raised tile plate 110 from swinging and descending due to the gravity of the mahjong tiles, and further improving the operation reliability and stability of the raised tile mechanism 100.

[0079] Furthermore, due to the swinging motion of the shift fork 140, the shift fork 140 is in a fixed position when the first sensor 171 is triggered. Therefore, only one sensing unit needs to be provided on the shift fork 140, thereby reducing costs.

[0080] In one embodiment, such as Figure 5 , Figure 6 , Figure 8 As shown, the card-raising mechanism 100 also includes a second sensor 172, which is triggered by the sensing unit at the card-lowering termination position of the card-raising plate 110. The first sensor 171 and the second sensor 172 are mounted on the same circuit board 170.

[0081] The tile-lifting mechanism 100 can detect through the second sensor 172 that the tile-lifting plate 110 is in the position of connecting with the tile-pushing groove 215, thereby stopping the rotation of the tile-lifting motor 200. At the same time, the detection signal of the second sensor 172 can also serve as the start signal of the tile-pushing component 220. The tile-pushing component 220 operates to push the mahjong tiles in the tile-pushing groove 215 to the tile-lifting plate 110 for the tilting tile-loading device to load the tiles.

[0082] In this embodiment, the sensing unit is a magnetic component, and the second sensor 172 is a Hall element.

[0083] In some other embodiments, the second sensor 172 may also be a photoelectric sensor, with the sensing unit being a through hole provided on the shift fork 140.

[0084] By setting the second sensor 172, the lifting motor 200 can be stopped when the lifting plate 110 descends to the connecting push plate slot 215. The detection signal of the second sensor 172 can also be used as the start signal of the push plate mechanism 200, so that the lifting mechanism 100 can cooperate with the push plate mechanism 200 to complete the pushing and lifting of the tilting plate feeding device. The first sensor 171 and the second sensor 172 are mounted on the same circuit board 170, which simplifies the assembly process and reduces the assembly cost.

[0085] Furthermore, due to the swinging motion of the shift fork 140, the shift fork 140 is in a fixed position when the second sensor 172 is triggered. Therefore, only one sensing unit needs to be provided on the shift fork 140, thereby reducing costs.

[0086] In one embodiment, such as Figure 4 As shown, there are multiple paddle blocks 131, which are circumferentially distributed on the drive wheel 130.

[0087] Specifically, referring to the figure, there are two paddle blocks 131, which are evenly distributed circumferentially on the drive wheel 130.

[0088] In some other embodiments, the pushing blocks 131 can also be arranged in three or more.

[0089] It can be understood that, due to the presence of the sensors, the pushing blocks 131 do not need to be evenly distributed circumferentially on the driving wheel 130.

[0090] By arranging the pushing blocks 131 on the driving wheel 130, the number of rotations of the tile lifting motor 200 in one reciprocating cycle of the tile lifting link 150 is reduced, thereby reducing the frequency and intensity of use of the tile lifting motor 200 and increasing the service life of the tile lifting motor 200.

[0091] In one embodiment, as shown in Figure 2 , Figure 7 , Figure 9 the driving wheel 130 and the shifting fork 140 are arranged on the side of the tile lifting link 150 away from the tile pushing groove 215.

[0092] Since the bottom of the tile pushing groove 215 is the bottom shell of the automatic mahjong machine, there is no space for installing other components below the tile pushing groove 215, and the top of the tile pushing groove 215 is the table panel of the automatic mahjong machine, which also has no space for installing other components. At the same time, since the tile pushing groove 215 is curved at an angle greater than 180°, the driving mechanism, control components are installed in the central region of the arc-shaped tile pushing groove 215. Arranging the driving wheel 130 and the shifting fork 140 on the side of the tile lifting link 150 away from the tile pushing groove 215 is to arrange the driving wheel 130 and the shifting fork 140 in the above-mentioned installation region, so that the driving components in the inclined tile lifting device can be arranged more compactly, avoiding the additional increase in the height of the inclined tile lifting device.

[0093] Through the above arrangement, the height of the driving wheel 130 and the shifting fork 140 is avoided to increase the height of the inclined tile lifting device, and the components inside the inclined tile lifting device can be more compact.

[0094] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Those skilled in the art should understand that the present application includes but is not limited to the contents described in the above specific embodiments and the drawings. Any modification that does not deviate from the functional and structural principles of the present application shall be included in the scope of the claims.
