Description

Technical Field

[0001] This utility model relates to the field of automatic mahjong machine technology, and in particular to the stacking mechanism of an automatic mahjong machine. Background Technology

[0002] The stacking and pushing mechanism in existing tilting automatic mahjong machines can be specifically referenced in Chinese Utility Model Patent Publication No. CN222641206U, entitled "An Arc-Shaped Mahjong Machine and Its Pushing Mechanism." The tile-bearing cam is driven by a motor to rotate horizontally. The cam has a tile-bearing curved groove, and the tile-bearing seat has a tile-bearing bearing that rolls into the groove. The rotation of the cam causes the bearing to roll to different positions on the groove, thus raising the tile-bearing seat to different heights.

[0003] The tile holder is used to receive the mahjong tiles pushed by the tile feeding mechanism. The tile holder is at different heights when receiving the first and second mahjong tiles to facilitate the triggering and recognition of the mahjong tile sensor. Therefore, the tile holder needs to be raised and lowered during operation.

[0004] In the existing technology, the card-bearing cam's card-bearing curve groove directly drives the card-bearing seat. Therefore, the height difference between the high and low positions in the card-bearing curve groove is large (at least the thickness of a mahjong tile). This results in the card-bearing cam occupying a large space in the height direction of the stacking mechanism, increasing the overall height of the stacking mechanism and the tilting card-feeding device. Utility Model Content

[0005] This utility model proposes a stacking and pushing mechanism, a tilting card-loading device, and an automatic mahjong machine with tilting card loading to overcome the shortcomings of the prior art, thereby solving the technical problem that the card-bearing cam occupies a large amount of space in the height direction of the stacking and pushing mechanism in the prior art.

[0006] To achieve the above technical objectives, the present invention proposes a stacking and pushing mechanism, including a card-bearing seat, a card-bearing swing rod, a card-bearing wheel, and a stacking and pushing motor unit. The side of the card-bearing wheel is provided with a card-bearing curved groove. The card-bearing swing rod includes a hinged end, a free end connected to the card-bearing seat, and a first transmission pin disposed between the hinged end and the free end. The first transmission pin drives the card-bearing curved groove. The stacking and pushing motor unit drives the card-bearing wheel to rotate, causing the card-bearing curved groove to drive the first transmission pin to move up and down. The movement of the first transmission pin causes the card-bearing swing rod to drive the card-bearing seat to move up and down.

[0007] The stacking mechanism of this utility model achieves its up-and-down swing of the card-bearing swing rod through the cooperation of the first transmission pin and the card-bearing curved groove. The first transmission pin is located between the hinge end and the free end of the card-bearing swing rod. The hinge end of the card-bearing swing rod is rotatably connected to the hinge point, and the free end of the card-bearing swing rod is connected to the card-bearing seat. The card-bearing swing rod forms a power arm from the hinge end to the first transmission pin and a resistance arm from the hinge end to the free end. The length of the power arm is less than the length of the resistance arm, making the card-bearing swing rod a lever that requires more effort. Under the condition that the lifting and lowering amplitude of the card-bearing seat is the same, the distance required for the first transmission pin to move up and down is reduced, and the height difference between the high and low positions in the card-bearing curved groove is reduced (making it less than the thickness of a mahjong tile). This allows the thickness of the card-bearing wheel to be reduced, thereby reducing the space occupied by the card-bearing wheel in the height direction of the stacking mechanism and reducing the overall height of the stacking mechanism and the tilting card-bearing device. At the same time, this arrangement makes the slope of the card-bearing curved groove driving the first transmission pin to move up and down more gentle, reducing the force between the card-bearing curved groove and the first transmission pin, and reducing the friction between the two.

[0008] Preferably, the first transmission pin is fitted with a bearing or roller that rolls into contact with the groove wall of the bearing groove.

[0009] By adopting the aforementioned technical solution, direct friction between the first transmission pin and the bearing groove is avoided, and sliding friction is transformed into rolling friction with less friction, thereby improving the service life of the first transmission pin and the bearing groove.

[0010] Preferably, the card holder has a first side surface parallel to the swing direction of the card holder lever, the first side surface is provided with a sliding groove, and the free end is provided with a connector extending laterally in the direction of the sliding groove, the connector extending into the sliding groove and being connected to the sliding groove in a transmission manner.

[0011] By adopting the aforementioned technical solution, the depth of the connector extending into the groove remains unchanged during the swing of the bearing swing rod, thereby improving the reliability of the transmission connection between the bearing swing rod and the bearing seat.

[0012] Preferably, the bearing groove includes an ascending section, a first horizontal section, a descending section, and a second horizontal section connected end to end along the rotation direction of the bearing wheel, so that the bearing groove surrounds the side of the bearing wheel. The ascending section drives the first transmission pin to rise, the first horizontal section keeps the first transmission pin in a high position, the descending section drives the first transmission pin to fall, and the lowest point of the descending section and the second horizontal section keep the first transmission pin in a low position.

[0013] By adopting the aforementioned technical solution, the card-bearing curved groove is designed to surround the side of the card-bearing wheel, so that the stacking and pushing motor completes the stacking and pushing of cards in one revolution, reducing the design difficulty of the stacking and pushing mechanism. Furthermore, the card-bearing curved groove includes an ascending section, a first horizontal section, a descending section, and a second horizontal section connected end to end. Each section is used to cooperate with other components of the tilting card-bearing device to complete the stacking and pushing of cards in the stacking and pushing mechanism, and to ensure that the card-bearing seat is in a stable working position during the stacking and pushing of cards, thereby improving the stability of the stacking and pushing mechanism in completing the stacking and pushing operation.

[0014] Preferably, the second horizontal segment includes a card-pushing segment connecting the descending segment, the card-pushing segment smoothly transitioning to the descending segment, and the card-pushing segment being higher than the lowest point of the descending segment.

[0015] By adopting the aforementioned technical solution, the lifting area of ​​the card holder can be lowered as a whole. That is, the installation position of the card holder can be lowered, thereby freeing up some space above the card holder for other components of the stacking mechanism, so that the overall height of the stacking mechanism can be further reduced.

[0016] Preferably, the stacking mechanism further includes a first sensor, and the bearing wheel is provided with a first sensing unit and a second sensing unit.

[0017] One end of the first transmission pin is located at the end of the rising segment or in the first horizontal segment, and the first sensing unit triggers the first sensor. One end of the first transmission pin is located at the lowest point of the falling segment, and the second sensing unit triggers the first sensor.

[0018] By adopting the aforementioned technical solution, and by setting a first sensor and a first sensing unit and a second sensing unit on the card-bearing wheel to trigger the first sensor, the tilting card-bearing device can accurately control the lifting height of the card-bearing seat by detecting the rotation position of the card-bearing wheel, thereby improving the accuracy of the stacking operation of the stacking mechanism.

[0019] Preferably, the stacking mechanism further includes a card-pushing lever that swings horizontally. One end of the card-pushing lever is rotatably connected to the card storage bracket, and the other end of the card-pushing lever is provided with a card-pushing head. A card-pushing groove is provided in the middle of the card-pushing lever, and a second transmission pin is provided on the upper end face of the card-bearing wheel. The second transmission pin is placed in the card-pushing groove to drive the card-pushing lever to swing.

[0020] By adopting the aforementioned technical solution, the pusher arm is set to swing horizontally above the bearing wheel, so that the bearing arm and the pusher arm move in different directions, avoiding interference between their movements and reducing the design difficulty of the stacking mechanism.

[0021] Preferably, the stacking mechanism further includes a second sensor, which is triggered when the pusher head is in the initial position, and a third sensing unit is provided on the card-bearing wheel for triggering the second sensor.

[0022] By adopting the aforementioned technical solution, and by setting a second sensor and a third sensing unit for triggering the second sensor, it is easier to control the stacking mechanism more accurately and improve the reliability of the stacking mechanism operation.

[0023] Preferably, the stacking motor unit includes a vertically arranged motor shaft, which drives the bearing wheel to rotate horizontally.

[0024] This utility model also proposes a tilting card loading device, including a card storage bracket, which has a card storage slot. The card storage slot includes a card inlet and a card outlet, and has an arc-shaped curved structure with a bending angle greater than 180° from the card inlet to the card outlet. The tilting card loading device also includes a stacking mechanism of any of the above technical solutions, which is installed on the card storage bracket.

[0025] The tilting license plate loading device of this utility model, because it adopts the stacking mechanism of any of the above-mentioned technical solutions, has all the technical effects of all the above-mentioned technical solutions.

[0026] Preferably, the upper surface of the card-bearing wheel is higher than the card inlet in the height direction of the card storage bracket. The card-bearing swing arm includes a first swing arm and a second swing arm. The hinged end is located on the first swing arm, and the free end is located on the second swing arm. The second swing arm extends downward from one end of the first swing arm and connects to the card-bearing seat.

[0027] This arrangement of the card-bearing swing arm allows the card-bearing wheel to be mounted close to the card storage bracket, thereby increasing the overlap range between the card-bearing wheel, the stacking motor unit, and the card storage bracket in the height direction, and further reducing the overall height of the tilting card-bearing device.

[0028] This utility model also proposes an automatic mahjong machine with tilted card-adding mechanism, including the tilted card-adding device as described in any of the above technical solutions.

[0029] Since the automatic mahjong machine with tilted card-feeding of this utility model adopts the tilted card-feeding device of any of the aforementioned technical solutions, the automatic mahjong machine has all the technical effects of the aforementioned technical solutions.

However, the following embodiments are only preferred embodiments of the present utility model and not all of them.

[0048] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0049] like Figures 3 to 4As shown, the automatic mahjong machine stacking mechanism 200 proposed in this embodiment includes a tile-bearing seat 220, a tile-bearing swing rod 250, a tile-bearing wheel 230, and a stacking motor unit 210. The tile-bearing wheel 230 has a tile-bearing curved groove 240 on its side. The tile-bearing swing rod 250 includes a hinged end 251, a free end 252 connecting the tile-bearing seat 220, and a first transmission pin (not shown) disposed between the hinged end 251 and the free end 252. The first transmission pin drives the tile-bearing curved groove 240. The stacking motor unit 210 drives the tile-bearing wheel 230 to rotate, causing the tile-bearing curved groove 240 to drive the first transmission pin to move up and down. The movement of the first transmission pin causes the tile-bearing swing rod 250 to drive the tile-bearing seat 220 to move up and down. The tile-bearing swing rod 250 is provided with a first transmission pin mounting hole 253 for mounting the first transmission pin.

[0050] Since the bearing swing arm 250 achieves its up-and-down swing through the cooperation of the first transmission pin and the bearing curved groove 240, and the first transmission pin is located between the hinge end 251 and the free end 252 of the bearing swing arm 250, the swing arm 250 swings around the hinge end 251, causing the free end 252 to drive the bearing seat 220 to move. The bearing swing arm 250 from the hinge end 251 to the first transmission pin forms a power arm, and the bearing swing arm 250 from the hinge end 251 to the free end 252 forms a resistance arm. The length of the power arm is less than the length of the resistance arm, making the bearing swing arm 250 a lever that requires more effort. The bearing seat 220 rises and falls at the same amplitude. In this way, the distance required for the first transmission pin to move up and down is reduced, and the height difference between the high and low positions in the tile-bearing curved groove 240 is reduced (making it less than the thickness of a mahjong tile). This allows the thickness of the tile-bearing wheel 230 to be reduced, thereby reducing the space occupied by the tile-bearing wheel 230 in the height direction of the stacking mechanism 200 and reducing the overall height of the stacking mechanism 200 and the tilting tile-feeding device. At the same time, this arrangement makes the slope of the tile-bearing curved groove 240 driving the first transmission pin to move up and down more gentle, thereby reducing the force between the tile-bearing curved groove 240 and the first transmission pin and reducing the friction between them.

[0051] In this embodiment, the hinge end 251 of the card-bearing swing arm 250 can be rotatably connected to the stacking motor unit 210, or it can be rotatably connected to the card storage bracket 100 of the tilting card-bearing device.

[0052] Automatic mahjong machines are typically equipped with four sets of tilting tile-feeding devices. Each tilting tile-feeding device includes a tile storage bracket 100, and a stacking mechanism 200 is mounted on the tile storage bracket 100. In this embodiment, the tile storage bracket 100 has a tile storage slot 110, which has a tile inlet 111 and a tile outlet 112. The tile storage slot 110 has an arc-shaped curved structure with a bending angle greater than 180° from the tile inlet 111 to the tile outlet 112, allowing the four sets of tilting tile-feeding devices to be positioned at the corners of the automatic mahjong machine. Furthermore, the four sets of tilting tile-feeding devices are independently configured and do not overlap.

[0053] In other embodiments, the tilting card-dispensing device of the automatic mahjong machine can also adopt the card-pushing mechanism described in Chinese Utility Model Patent No. CN200966910Y, entitled "Slope Card-Dispensing Device for Fully Automatic Mahjong Machine". In this patent, four arc-shaped card-pushing grooves 262 arranged in a windmill shape are provided below the mahjong machine table.

[0054] The tile holder 220 is used to cooperate with the tile feeding mechanism in the tilting tile feeding device to receive the mahjong tiles pushed by the tile feeding mechanism and complete the stacking and pushing operation of the mahjong tiles. The tile feeding device of the automatic mahjong machine can be referred to Chinese Utility Model Patent with publication number CN210409490U, entitled "Title Stacking Mechanism and Mahjong Machine Tile Feeding Device".

[0055] The stacking and pushing mechanism 200 also includes a mahjong tile sensor. The tile holder 220 is in a high position to receive the first mahjong tile. After the first mahjong tile triggers the sensor, the tile holder 220 descends to a low position to receive the second mahjong tile. After the second mahjong tile triggers the sensor, the stacking and pushing mechanism 200 pushes the mahjong tile into the tile storage slot 110. The tile pushing component in the stacking and pushing mechanism 200 will be described in subsequent embodiments. The lifting and lowering of the tile holder 220 is used to complete the stacking action in the stacking and pushing operation, that is, to stack two mahjong tiles on the tile holder 220. The tile pushing component is used to complete the pushing action in the stacking and pushing operation, that is, to push the mahjong tiles stacked on the tile holder 220 into the tile storage slot 110 of the tilting tile feeding device.

[0056] In this preferred embodiment, a bearing or roller that rolls into contact with the groove wall of the bearing curved groove 240 is sleeved on the first transmission pin.

[0057] In one embodiment, based on all the foregoing embodiments, such as Figure 3 , Figure 4 As shown, the card holder 220 has a first side 221 parallel to the swing direction of the card holder swing rod 250. The first side 221 is provided with a groove 222. The free end 252 is provided with a connector 2521 extending laterally in the direction of the groove 222. The connector 2521 extends into the groove 222 and is connected to the groove 222 in a transmission manner.

[0058] This design ensures that the depth of the connector 2521 extending into the slide groove 222 remains constant during the swing of the bearing swing rod 250, thereby improving the reliability of the transmission connection between the bearing swing rod 250 and the bearing seat 220.

[0059] In this embodiment, the slide 222 extends horizontally, and the length of the slide 222 is greater than the diameter of the connector 2521, so that the connector 2521 is in different positions in the slide 222 during the swing of the bearing swing rod 250.

[0060] In some other embodiments, the groove 222 may also be an inclined extension.

[0061] In one embodiment, based on all the foregoing embodiments, the card-pushing component in the stacking mechanism 200 will be described, such as... Figure 2 , Figure 3 As shown, the stacking mechanism 200 also includes a horizontally swinging card-pushing lever 260. One end of the lever 260 is rotatably connected to the card storage bracket 100, and the other end is provided with a card-pushing head 261. A card-pushing groove 262 is provided in the middle of the lever 260. A second transmission pin (not shown) is provided on the upper end face of the card-bearing wheel 230. The second transmission pin is placed in the card-pushing groove 262 to drive the lever 260 to swing back and forth. The upper end face of the card-bearing wheel 230 is provided with a second transmission pin mounting hole 231 for mounting the second transmission pin.

[0062] In this embodiment, a bearing or roller that rolls into the push plate groove 262 is mounted on the second transmission pin.

[0063] The reciprocating swing of the pusher lever 260 is used to push the mahjong tiles on the tile holder 220 into the tile inlet 111, and resets after the pushing action is completed, freeing up space on the tile holder 220 to hold the tiles.

[0064] By setting the pusher arm 260 to swing horizontally above the bearing wheel 230, the bearing arm 250 and the pusher arm 260 move in different directions, avoiding interference between their movements and reducing the design difficulty of the stacking mechanism 200.

[0065] In one embodiment, based on the foregoing embodiments, such as Figure 3 , Figure 4 As shown, the stacking motor unit 210 includes a vertically arranged motor shaft 2111, which drives the bearing wheel 230 to rotate horizontally.

[0066] The horizontal rotation of the card-bearing wheel 230 enables the second transmission pin on its upper end face to engage with the card-pushing swing arm 260 for transmission, and the card-bearing transmission groove 240 on its side face to engage with the card-bearing swing arm 250 for transmission, thereby completing the stacking operation of the stacking mechanism 200.

[0067] In one embodiment, based on all the foregoing embodiments, such as Figure 3 , Figures 6 to 9As shown, the card-bearing curved groove 240 includes an ascending section 241, a first horizontal section 242, a descending section 243, and a second horizontal section 244 connected end-to-end along the rotation direction of the card-bearing wheel 230, such that the card-bearing curved groove 240 surrounds the side of the card-bearing wheel 230. The ascending section 241 drives the first transmission pin to rise, and the first horizontal section 242 connects to the ascending section 241, so that the card-bearing seat 220 is in a high position to receive the first mahjong tile. The descending section 243 drives the first transmission pin to descend, and the card-bearing seat 220 descends from the high position to the low position. The lowest point of the descending section 243 puts the card-bearing seat 220 in a low position to receive the second mahjong tile. The second horizontal section 244 connects to the descending section 243, and the second horizontal section 244 puts the card-bearing seat 220 in a low position, which is used to cooperate with the card-pushing component in the stacking and pushing mechanism 200 to complete the card-pushing action of pushing the mahjong tile on the card-bearing seat 220 into the card-inlet 111.

[0068] The card-bearing curved groove 240 is designed to surround the side of the card-bearing wheel 230, so that the card-bearing wheel 230 completes the card stacking and pushing of the stacking and pushing mechanism 200 in one rotation, reducing the design difficulty of the stacking and pushing mechanism 200. In addition, the card-bearing curved groove 240 includes an ascending section 241, a first horizontal section 242, a descending section 243 and a second horizontal section 244 connected end to end. Each section is used to cooperate with other components of the tilting card-bearing device to complete the card stacking and pushing of the stacking and pushing mechanism 200, and to keep the card-bearing seat 220 in a stable working position during the card stacking and pushing action, thereby improving the stability of the stacking and pushing mechanism 200 in completing the stacking and pushing action.

[0069] In a preferred embodiment, such as Figure 8 , Figure 9 As shown, the second horizontal segment 244 includes a card-pushing segment 2441 that connects to the descending segment 243. The card-pushing segment 2441 and the descending segment 243 have a smooth transition, and the card-pushing segment 2441 is higher than the lowest point of the descending segment 243.

[0070] The tile holder 220 is in a low position to receive the second mahjong tile and to cooperate with the tile pusher to push the mahjong tile into the tile inlet 111.

[0071] In this embodiment, the low position includes a first low position and a second low position. The first low position is lower than the second low position. When one end of the first transmission pin is at the lowest point of the descending segment 243, the card holder 220 is in the first low position. When one end of the first transmission pin is in the pushing segment 2441, the card holder 220 is in the second low position.

[0072] In other words, after receiving the second mahjong tile, the tile holder 220 is slightly raised, and then, in conjunction with the tile pushing component, pushes the mahjong tile into the tile inlet 111.

[0073] In this way, the lifting area of ​​the card holder 220 can be lowered as a whole, that is, the installation position of the card holder 220 can be lowered relatively, thereby freeing up some space above the card holder 220 for other components of the stacking mechanism 200, so that the overall height of the stacking mechanism 200 can be further reduced.

[0074] Other components of the stacking and pushing mechanism 200 include a card pusher head 261 and a card holder 220, which can provide some space for the card pusher head 261 of the card pusher lever 260, allowing the position of the card pusher head 261 to be lowered.

[0075] In another preferred embodiment, such as Figure 4 , Figure 6 , Figure 7 As shown, the stacking mechanism 200 also includes a first sensor 300, and the bearing wheel 230 is provided with a first sensing unit 310 and a second sensing unit 320. One end of the first transmission pin is located at the end of the rising section 241 or in the first horizontal section 242, and the first sensing unit 310 triggers the first sensor 300. One end of the first transmission pin is located at the lowest point of the falling section 243, and the second sensing unit 320 triggers the first sensor 300.

[0076] The tilting tile-feeding device also includes a main control board. During one stacking process of the stacking mechanism 200, the first sensor 300 is triggered by the first sensing unit 310 and sends a first trigger signal to the main control board. The tilting tile-feeding device controls the tile-feeding mechanism to deliver the first mahjong tile to the tile-bearing seat 220. The first sensor 300 is triggered by the second sensing unit 320 and the main control board sends a second trigger signal. The tilting tile-feeding device controls the tile-feeding mechanism to deliver the second mahjong tile to the tile-bearing seat 220.

[0077] In this device, the first sensing unit 310 and the second sensing unit 320 trigger the same signal generated by the first sensor 300. The main control board can control the operation of each component in the tilting license plate issuing device based on whether the signal sequence number sent by the first sensor 300 is odd or even. Alternatively, the main control board can reset the signal sequence number of the first sensor 300 to zero after the first sensor 300 sends two trigger signals, thereby controlling the operation of each component in the tilting license plate issuing device based on the first and second signals.

[0078] By setting a first sensor 300 and setting a first sensing unit 310 and a second sensing unit 320 on the card-bearing wheel 230 to trigger the first sensor 300, the tilting card-feeding device can accurately control the lifting height of the card-bearing seat 220 by detecting the rotation position of the card-bearing wheel 230, thereby improving the accuracy of the stacking operation of the stacking mechanism 200.

[0079] More preferably, the first sensor 300 and the bearing lever 250 are located on opposite sides of the bearing wheel 230.

[0080] Since the card-bearing swing arm 250 is connected to the card-bearing wheel 230 via the first transmission pin, the card-bearing swing arm 250 is located close to the card-bearing wheel 230. The first sensor 300 and the card-bearing swing arm 250 are located on opposite sides of the card-bearing wheel 230, which avoids interference between the card-bearing swing arm 250 and the first sensor 300, and also allows the distance between the first sensor 300 and the card-bearing wheel 230 to be set smaller, thereby improving the sensing accuracy of the first sensor 300.

[0081] In one embodiment, based on the aforementioned card-pushing component, such as... Figure 4 , Figure 6 , Figure 7 As shown, the stacking mechanism 200 also includes a second sensor 400, which is triggered when the pusher head 261 is in the initial position. The card-bearing wheel 230 is provided with a third sensing unit 410 for triggering the second sensor 400.

[0082] When the automatic mahjong machine is first turned on or after the stacking mechanism 200 completes the stacking operation, the pusher head 261 is in the initial position. The third sensing unit 410 keeps triggering the second sensor 400 so that the main control board can determine that the stacking mechanism 200 is at the working zero point, thereby facilitating the main control board to accurately control the operation of the stacking mechanism 200.

[0083] By setting a second sensor 400 and a third sensing unit 410 for triggering the second sensor 400, it is easier to control the stacking mechanism 200 more accurately and improve the reliability of the stacking mechanism 200 operation.

[0084] The detection heights of the first sensor 300 and the second sensor 400 are different, and the installation heights of the first sensing unit 310 and the second sensing unit 320 are different from those of the third sensing unit 410, thereby preventing the third sensing unit 410 from triggering the first sensor 300, and preventing the first sensing unit 310 and the second sensing unit 320 from triggering the second sensor 400.

[0085] The first sensor 300 and the second sensor 400 are mounted on the same circuit board, which simplifies the design and reduces costs.

[0086] In this embodiment, the initial position of the pusher head 261 is located above the card holder 220.

[0087] In this way, the pusher head 261 can limit the pushing of mahjong tiles onto the tile holder 220, preventing the automatic mahjong machine's tile feeding device from continuing to feed mahjong tiles onto the tile holder 220 when the stacking mechanism 200 stops working, thereby ensuring the reliability of the tilting tile feeding device.

[0088] In another preferred embodiment, such as Figure 3 , Figure 4As shown, the second sensor 400 and the bearing lever 250 are located on opposite sides of the bearing wheel 230.

[0089] Since the card-bearing swing arm 250 is connected to the card-bearing wheel 230 via the first transmission pin, the card-bearing swing arm 250 is located close to the card-bearing wheel 230. The second sensor 400 and the card-bearing swing arm 250 are located on opposite sides of the card-bearing wheel 230, which avoids interference between the card-bearing swing arm 250 and the second sensor 400, and also allows the distance between the second sensor 400 and the card-bearing wheel 230 to be set smaller, thereby improving the sensing accuracy of the second sensor 400.

[0090] This utility model also proposes a tilting license plate issuing device, such as... Figures 1 to 4 As shown, the stacking mechanism 200 includes all the aforementioned embodiments. The tilting card loading device of this embodiment includes a card storage bracket 100, which is provided with a card storage slot 110. The card storage slot 110 includes a card inlet 111 and a card outlet 112, and has an arc-shaped curved structure with a bending angle greater than 180° from the card inlet 111 to the card outlet 112. The stacking mechanism 200 is installed on the card storage bracket 100.

[0091] In one embodiment, such as Figures 2 to 4 As shown, in the tilting card-loading device based on the aforementioned embodiment, the upper end face of the card-bearing wheel 230 is higher than the card-inlet 111 in the height direction of the card storage bracket 100. The card-bearing swing arm 250 includes a first swing arm 254 and a second swing arm 255. The hinged end 251 is provided on the first swing arm 254, and the free end 252 is provided on the second swing arm 255. The second swing arm 255 extends downward from one end of the first swing arm 254 and connects to the card-bearing seat 220.

[0092] The arrangement of the card-bearing swing arm 250 allows the card-bearing wheel 230 to be mounted close to the card storage bracket 100, thereby increasing the overlap range between the card-bearing wheel 230, the stacking motor unit 210 and the card storage bracket 100 in the height direction, and further reducing the overall height of the tilting card-bearing device.

[0093] This utility model also proposes an automatic mahjong machine with tilted card-feeding, including the tilted card-feeding device of any of the foregoing embodiments.

Those skilled in the art should understand that this utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
