Description

Technical Field

[0001] This utility model relates to the field of automatic mahjong machine technology, and in particular to a tilting tile-loading device for an automatic mahjong machine. Background Technology

[0002] An automatic mahjong machine with tilting tile feeding includes a tilting tile feeding device, which includes a lifting bracket and a stacking mechanism. The lifting bracket is provided with a tile storage slot for storing mahjong tiles. The stacking mechanism includes a tile-bearing wheel, a tile-bearing seat, a stacking motor, a tile-bearing wheel, and a tile-pushing lever. The rotation of the tile-bearing wheel drives the tile-bearing seat to move up and down, and the tile-pushing lever to push the tiles.

[0003] In existing automatic mahjong machines, the stacking motor in the tilting tile-feeding device is installed from bottom to top at the bottom of the lifting bracket. The motor shaft of the stacking motor passes through the bottom of the lifting bracket from bottom to top, the tile-bearing wheel is installed on the motor shaft, and the tile-bearing seat and the tile-pushing lever are installed on the upper part of the lifting bracket. For details, please refer to Chinese utility model patent with publication number CN222641206U, entitled "A Mahjong Machine with Arc-Shaped Tiles-Feeding and Its Tiles-Pushing Mechanism". Due to this design of the existing technology, the stacking motor and other stacking components in the stacking mechanism need to be installed on both sides of the lifting bracket. This results in the stacking mechanism being installed on the lifting bracket requiring at least two processes: bottom installation and top installation. This increases the number of operators required, and the semi-finished products being transferred between the two workstations increases the labor cost of assembly. Utility Model Content

[0004] This utility model proposes a tilting card-feeding device and an automatic mahjong machine with tilting card-feeding to overcome the shortcomings of the prior art, thereby solving the problem of high assembly difficulty caused by assembling the stacking motor and other stacking components on both sides of the lifting bracket in the prior art.

[0005] To achieve the above technical objectives, this utility model proposes a tilting card-loading device, including a card storage bracket. The card storage bracket includes an installation platform for supporting card-loading accessories and a card storage groove surrounding the outer periphery of the installation platform. The card storage groove 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.

[0006] The mounting platform has a first mounting surface on the same side as the card storage slot and a second mounting surface opposite to the first mounting surface. The card loading accessory includes a stacking motor unit and a stacking assembly driven by the stacking motor unit to perform stacking operations. The stacking motor unit has a first supporting flange. The mounting platform has a first mounting hole. The stacking motor unit passes through the first mounting hole from the first mounting surface to the second mounting surface. The first supporting flange is supported on the first mounting surface around the first mounting hole and connected to the mounting platform.

[0007] The tilting card-loading device of this utility model is provided with a first surface on the same side as the card storage slot and a second surface opposite to the first surface. The first surface is used to support a first support flange of the stacking motor unit, so that the mounting platform can support the stacking motor unit on the first surface side. This provides at least two assembly methods for the stacking motor unit and the stacking assembly: First, the stacking motor unit and the stacking assembly are respectively assembled onto the mounting platform on the first surface side; Second, the stacking motor unit and at least part of the stacking assembly are first assembled into a whole, and the whole or the whole and the remaining stacking assembly are assembled onto the mounting platform on the first surface side. In this way, the stacking motor unit and the stacking assembly can be assembled on the same side of the card storage bracket, and the assembly of the stacking motor unit and the stacking assembly does not need to be operated in two separate workstations. At the same time, the stacking motor unit can be assembled into a whole with at least part of the stacking assembly and then assembled onto the card storage bracket, further optimizing the assembly process. In addition, the stacking motor unit can also be disassembled on the first surface side, without needing to remove the card storage bracket and then disassemble the stacking motor unit from the second surface side of the card storage bracket as in the prior art.

[0008] Preferably, the card-loading accessory further includes a card-pushing motor and a card-pushing tray. The mounting platform has a third surface on the same side as the card storage slot and a fourth surface opposite to the first surface. The mounting platform has a second mounting hole. The card-pushing motor has a second supporting flange. The card-pushing motor passes through the second mounting hole from the third surface to the fourth surface. The second supporting flange is supported on the third surface around the second mounting hole and is fixedly connected to the mounting platform.

[0009] Using the aforementioned technical solution, similar to the principle of installing the stacking push motor unit and stacking push assembly on the same side of the mounting platform, the above-mentioned arrangement allows the push motor and push tray to be assembled on the same side of the card storage bracket. The assembly of the two does not require two separate workstations, and the replacement of the push motor does not require disassembling the card storage bracket. At the same time, the third surface is on the same side as the first surface, allowing the stacking push motor unit, stacking push assembly, push motor, and push tray to be assembled on the same side of the card storage bracket.

[0010] Preferably, the installation platform includes a first-level step and a second-level step on the same side as the card storage slot. The height of the first-level step on the installation platform is higher than that of the second-level step on the installation platform. The bottom of the card pusher is provided with a gear driven by a card pusher motor. The gear is installed on the first-level step. The first mounting hole is located on the second-level step. The orthographic projection of the gear overlaps with the orthographic projection of the stacking pusher motor unit.

[0011] By adopting the aforementioned technical solution, and by setting first-level and second-level steps of different heights, the installation height of the card pusher on the installation platform is higher than that of the stacking motor unit on the installation platform. The card pusher and the stacking motor unit have a certain overlap on the installation platform. This overlap allows the card pusher and the stacking motor unit to be assembled more compactly on the installation platform.

[0012] Preferably, the installation platform further includes a first limiting groove on the same side as the card storage slot, and the stacking and pushing assembly includes a card pushing swing rod with one end rotatably connected in the first limiting groove. The first limiting groove extends from one end of the second-level step to the first-level step, so that the orthographic projection of the gear overlaps with the orthographic projection of the card pushing swing rod.

[0013] Using the aforementioned technical solution, the limiting groove extends from one end of the second-level step to the first-level step, so that the installation height of the pusher arm on the installation platform is lower than the installation height of the pusher plate. The orthographic projection of the gear overlaps with the orthographic projection of the pusher arm, allowing the pusher plate and the pusher arm to be assembled more compactly on the installation platform.

[0014] Preferably, the first-level step has a first sidewall that connects to the second-level step, and the first sidewall forms a second limiting groove around the first mounting hole to limit the first supporting flange.

[0015] When the aforementioned technical solution is adopted, the stacked push motor unit is assembled onto the installation platform, and the first support flange is circumferentially positioned by the first positioning groove, which facilitates the assembly operation of the operator and reduces the assembly difficulty.

[0016] Preferably, the mounting platform further includes a three-tiered step on the same side as the card storage slot. The height of the first-tier step on the mounting platform is higher than that of the third-tier step on the mounting platform. The second mounting hole is located in the third-tiered step. The first-tiered step has a second sidewall that connects to the third-tiered step. The second sidewall circumferentially surrounds the second mounting hole to form a third limiting groove that limits the second supporting flange.

[0017] Using the aforementioned technical solution, when the pusher motor is assembled onto the installation platform, the second support flange is circumferentially positioned by the second positioning groove, which facilitates the assembly operation of the operator and reduces the assembly difficulty.

[0018] Preferably, the first mounting hole has a positioning groove on its wall and the first support flange has a positioning part that positions and cooperates with the positioning groove, so that the stacking motor unit is positioned on the mounting platform.

[0019] By adopting the aforementioned technical solution, the positioning groove and positioning rib can be used to more accurately position and assemble the stacking motor unit onto the installation platform, which helps to improve the assembly accuracy of the stacking motor unit and the matching accuracy between the stacking motor unit and the stacking assembly.

[0020] Preferably, the card storage bracket further includes a hollow structure surrounding the outer periphery of the mounting platform and connecting both ends of the card storage slot, the hollow structure extending into the inner side of the mounting platform to form the first mounting hole.

[0021] Using the aforementioned technical solution, the hollow structure on the storage bracket extends towards the inside of the mounting platform to form the first mounting hole, thus avoiding interference between the hole wall of the first mounting hole and the stacking operation of the stacking component.

[0022] Preferably, the stacking and pushing assembly includes a card-bearing wheel, a card-bearing swing rod, and a card-bearing seat. The stacking and pushing motor unit includes a stacking and pushing motor body with a motor shaft and a motor base for mounting the stacking and pushing motor body. The first support flange is disposed on the motor base. The card-bearing seat and the card-bearing swing rod are mounted on the motor base. A guide seat is provided on the motor base to guide the lifting direction of the card-bearing seat. The card-bearing wheel is mounted on the motor shaft, so that the card-bearing wheel, the card-bearing swing rod, the card-bearing seat, and the stacking and pushing motor unit are assembled into a whole and then installed on the mounting platform.

[0023] By adopting the aforementioned technical solution, since the bearing wheel, bearing swing arm, bearing seat, stacking motor body and motor base are all small parts, it is relatively easy to assemble multiple small parts into a whole; and since the installation platform can only provide limited installation and operation space for the stacking assembly and stacking motor unit, assembling the bearing wheel, bearing swing arm, bearing seat and stacking motor unit into a whole and then installing it onto the installation platform can greatly reduce the operational difficulty of assembling the stacking assembly and stacking motor unit onto the installation platform.

[0024] Preferably, the bearing swing arm swings up and down relative to the motor base, and the hole wall on one side of the first mounting hole is provided with a clearance groove to avoid the bearing swing arm.

[0025] By adopting the aforementioned technical solution, interference between the movement of the bearing swing arm and the wall of the first mounting hole is avoided.

[0026] This utility model also proposes an automatic mahjong machine with tilted card-feeding, which adopts any of the above-mentioned technical solutions for tilted card-feeding devices.

[0027] The automatic mahjong machine of this utility model, by adopting the tilting card-feeding device of any of the above-mentioned technical solutions, has all the technical effects of the above-mentioned technical solutions.

[0048] like Figures 1 to 6 As shown, the present invention proposes a tilting license plate loading device, including a license plate storage bracket 100. The license plate storage bracket 100 includes an installation platform 110 for carrying license plate loading accessories and a license plate storage slot 101 surrounding the outer periphery of the installation platform 110.

[0049] The card storage slot 101 includes a card inlet 1011 and a card outlet 1012, and the section from the card inlet 1011 to the card outlet 1012 has an arc-shaped curved structure with a bending angle greater than 180°, allowing the tilting card-feeding device to be installed at a corner of the automatic mahjong machine. The automatic mahjong machine has four sets of tilting card-feeding devices, which are independently set and do not overlap with each other.

[0050] The mounting platform 110 has a first surface 111 on the same side as the card storage slot 101 and a second surface opposite to the first surface 111. The card loading accessories include a stacking motor unit 200 and a stacking assembly 300 driven by the stacking motor unit 200 to perform stacking operations. The stacking motor unit 200 has a first support flange 221, and the mounting platform 110 has a first mounting hole 120. The stacking motor unit 200 passes through the first mounting hole 120 from the first surface 111 toward the second surface. The first support flange 221 is supported on the first surface 111 surrounding the first mounting hole 120 and is fixedly connected to the mounting platform 110.

[0051] The tile storage slot 101 is used to store mahjong tiles and has an upward-opening opening. The first surface 111 is on the same side as the tile storage slot 101. The stacking motor unit 200 is supported on the mounting platform 110 by the first surface 111, and the stacking motor unit 200 can be assembled onto the mounting platform 110 from the first surface side. Here, the first surface 111 refers to the surface on the mounting platform 110 that supports the first support flange 221, and the first surface side refers to the space above the first surface 111.

[0052] It should be noted that the first surface 111 provides support force to the stacking motor unit 200 by connecting to the first support flange 221. The support force can be provided by the first surface 111 to the first support flange 221 or by providing a frictional force with a support function. Therefore, the first surface 111 can be a plane, an inclined plane, or a vertical plane.

[0053] The stacking and pushing motor unit 200 includes a bottom end and a driving end. The bottom end passes through the first mounting hole 120, and the driving end is provided with a motor shaft 211. The stacking and pushing assembly 300 includes a card-bearing wheel 310, a card-bearing swing rod 330 and a card-pushing swing rod 340 driven by the rotation of the card-bearing wheel 310, and a card-bearing seat 320 that moves up and down driven by the card-bearing swing rod 330.

[0054] In some embodiments, the stacking and pushing motor unit 200 is assembled to the mounting platform 110 on the first surface side, exposing the motor shaft 211 on the first surface side. The card-bearing wheel 310, as a transmission component in the stacking and pushing assembly 300, is mounted to the motor shaft 211 on the first surface side. The card-bearing swing arm 330, the card-pushing swing arm 340, and the card-bearing seat 320 are assembled on the mounting platform 110 on the first surface side in a transmission connection with the card-bearing wheel 310, such that the stacking and pushing motor unit 200 and the stacking and pushing assembly 300 are assembled on the same side of the mounting platform.

[0055] In some other embodiments, the card-bearing wheel 310 may be first mounted on the motor shaft 211, and the card-bearing seat 320 and the card-bearing swing arm 330 may be mounted on the stacking and pushing motor unit 200 in a driving connection with the card-bearing wheel 310 to form a whole assembly, so that this whole assembly can be assembled onto the mounting platform 110 on the first surface side. The card-pushing swing arm 340 is mounted above the card-bearing wheel 310, so that the card-pushing swing arm 340 is also assembled onto the mounting platform 110 from the first surface side, so that the stacking and pushing motor unit 200 and the stacking and pushing assembly 300 are assembled on the same side of the mounting platform.

[0056] In some other embodiments, the card holder 320, card holder swing rod 330, card holder wheel 310, card pusher swing rod 340 and stacking pusher motor unit 200 may be assembled as a whole, and the whole assembly may be assembled onto the mounting platform 110 on the first surface side, so that the stacking pusher motor unit 200 and the stacking pusher assembly 300 are assembled on the same side of the mounting platform.

[0057] The tilting card-loading device of this utility model is provided with a first surface 111 on the same side as the card storage slot 101 and a second surface opposite to the first surface 111. The first surface 111 is used to support the first support flange 221 of the stacking motor unit 200, so that the mounting platform 110 can support the stacking motor unit 200 on the first surface side. This provides at least two assembly methods for the stacking motor unit 200 and the stacking assembly 300: First, the stacking motor unit 200 and the stacking assembly 300 are respectively assembled onto the mounting platform 110 on the first surface side; Second, the stacking motor unit 200 and at least part of the stacking assembly 300 are first assembled to form a whole, and this whole or the whole and the remaining stacking assembly 300 are then assembled together. The push assembly 300 is assembled to the mounting platform on the first surface side. In this way, the stacked push motor unit 200 and the stacked push assembly 300 can be assembled on the same side of the card storage bracket 100, and the assembly of the stacked push motor unit 200 and the stacked push assembly 300 does not need to be carried out in two separate workstations. At the same time, the stacked push motor unit 200 can be assembled with at least part of the stacked push assembly 300 as a whole before being assembled to the card storage bracket 100, which further optimizes the assembly process. In addition, the stacked push motor unit 200 can also be disassembled on the first surface side, without having to remove the card storage bracket 100 and then disassemble the stacked push motor unit 200 from the second surface side of the card storage bracket 100 as required by the prior art.

[0058] In this embodiment, the first support flange 221 is detachably connected to the mounting platform 110 by screws.

[0059] In some other embodiments, the first support flange 221 may also be connected to the mounting platform 110 by a snap-fit ​​connection.

[0060] In this embodiment, the stacking assembly 300 is used to perform the stacking operation. For example... Figure 5 , Figure 7 As shown, the stacking and pushing assembly 300 includes a tile holder 320, which is used to perform the stacking action in the stacking and pushing operation. The automatic mahjong machine also includes a tile feeding mechanism, which picks up tiles from the shuffling tray of the automatic mahjong machine and feeds them to the tile holder 320. The tile holder 320 is in a high position when receiving the first mahjong tile and in a low position when receiving the second mahjong tile. The stacking action refers to the lifting and lowering action of the tile holder 320 when receiving mahjong tiles. The stacking and pushing assembly 300 also includes a tile pushing lever 340, which is used to perform the pushing action in the stacking and pushing operation. When two mahjong tiles are stacked on the tile holder 320, the tile pushing lever 340 pushes the two mahjong tiles on the tile holder 320 into the tile inlet 1011 of the tile storage slot. The pushing action refers to this pushing action of the tile pushing lever 340.

[0061] Among them, the card-delivering mechanism can refer to the Chinese utility model patent with publication number CN210409490U, entitled "Card Stacking Mechanism and Card-Delivering Device for Mahjong Machine", and the Chinese utility model patent with publication number CN205699375U, entitled "Card-Delivering Mechanism for Fully Automatic Mahjong Machine".

[0062] The stacking and pushing component 300 can be referenced in the Chinese utility model patent with publication number CN222641206U, entitled "An Arc-Shaped Mahjong Machine and Its Pushing Mechanism".

[0063] In one embodiment, such as Figure 1 , Figure 2 , Figure 7 As shown in the aforementioned embodiment, the card-loading accessory further includes a card-pushing motor 400 and a card-pushing tray 500. The mounting platform 110 also has a third surface 112 on the same side as the card storage slot 101 and a fourth surface opposite to the third surface 112. The card-pushing motor 400 has a second supporting flange 410, and the mounting platform 110 has a second mounting hole 130. The card-pushing motor 400 passes through the second mounting hole 130 from the third surface 112 to the fourth surface. The second supporting flange 410 is supported on the third surface 112 around the second mounting hole 130 and is fixedly connected to the mounting platform 110.

[0064] The second support flange 410 is detachably connected to the mounting platform 110 by screws.

[0065] Similar to the principle of installing the stacking push motor unit 200 and the stacking push assembly 300 on the same side of the mounting platform 110, the above-mentioned arrangement allows the push card motor 400 and the push card tray 500 to be assembled on the same side of the card storage bracket 100. The assembly of the two does not require two separate workstations, and the replacement of the push card motor 400 does not require disassembling the card storage bracket 100. At the same time, the third surface 112 is on the same side as the first surface 111, so that the stacking push motor unit 200, the stacking push assembly 300, the push card motor 400 and the push card tray 500 can be assembled on the same side of the card storage bracket 100.

[0066] In this embodiment, the pusher motor 400 and the pusher plate 500 constitute the pusher mechanism. The working principle of the pusher mechanism can be referred to the Chinese utility model patent with publication number CN207928699U entitled "Ring Pusher Device for Automatic Mahjong Machine" and "Automatic Mahjong Machine", or the Chinese utility model patent with publication number CN205699378U entitled "Pick-up and Transport Device for Fully Automatic Mahjong Machine".

[0067] The tilting tile-loading device also includes a tile-lifting mechanism, and a tile-pushing mechanism that works in conjunction with the tile-lifting mechanism to push the mahjong tiles in the storage slot onto the table of the automatic mahjong machine. The tile-lifting mechanism can be found in Chinese invention patent application CN109011552A, entitled "A Fully Automatic Mahjong Machine," and Chinese invention patent application CN107982910A, entitled "A Tilting Tile-Lifting Mechanism for a Mahjong Machine and an Automatic Mahjong Machine."

[0068] In one embodiment, such as Figures 1 to 7 As shown, based on the previous embodiment, the installation platform 110 includes a first-level step 140 and a second-level step 150 on the same side as the card storage slot 101. The height of the first-level step 140 on the installation platform 110 is higher than the height of the second-level step 150 on the installation platform 110. The bottom of the card pusher 500 is provided with a gear 510 driven by the card pusher motor 400. The gear 510 is installed on the first-level step 140, and the first mounting hole 120 is located on the second-level step 150. The orthographic projection of the gear 510 overlaps with the orthographic projection of the stacked pusher motor unit 200.

[0069] The first surface 111 includes the upper surface of the first-level step 140 and the upper surface of the second-level step 150. Since the first-level step 140 is higher than the second-level step 150, the installation height of the card pusher 500 on the mounting platform 110 is higher than that of the stacked pusher motor unit 200. The difference in installation height between the two ensures that the gear 510 at the bottom of the card pusher 500 overlaps with the orthographic projection of the stacked pusher motor unit 200 without causing interference between the card pusher 500 and the stacked pusher motor unit 200. This allows the card pusher 500 and the stacked pusher motor unit 200 to be assembled more compactly on the mounting platform 110.

[0070] By setting a first-level step 140 and a second-level step 150 with different heights, the installation height of the card pusher 500 on the installation platform 110 is higher than that of the stacked pusher motor unit 200 on the installation platform 110. The card pusher 500 and the stacked pusher motor unit 200 have a certain overlap on the installation platform 110. This overlap allows the card pusher 500 and the stacked pusher motor unit 200 to be assembled more compactly on the installation platform 110.

[0071] In a preferred embodiment, such as Figures 2 to 7 As shown, the installation platform 110 also includes a first limiting groove 160 on the same side as the card storage slot 101. The stacking and pushing assembly 300 includes a card pushing lever 340 with one end rotatably connected in the first limiting groove 160. The first limiting groove 160 extends from one end of the secondary step 150 to the primary step 140, so that the orthographic projection of the gear 510 overlaps with the orthographic projection of the card pushing lever 340.

[0072] The pusher arm 340 is used to perform the pushing action in the stacking and pushing operation of the stacking and pushing assembly 300. The stacking and pushing assembly 300 also includes a card-bearing wheel 310. The pusher arm 340 is provided with a card-pushing groove 341. The upper end face of the card-bearing wheel 310 is provided with a first transmission pin that slides in the card-pushing groove 341. The stacking and pushing motor unit 200 drives the card-bearing wheel 310 to rotate, so that the first transmission pin drives the pusher arm 340 to perform a reciprocating card-pushing motion. The first limiting groove 160 is used to determine the installation position of the pusher arm 340, limit the swing range of the pusher arm 340, and support one end of the pusher arm 340.

[0073] The first limiting groove 160 extends from one end of the second-level step 150 to the first-level step 140, so that the installation height of the pusher arm 340 on the mounting platform 110 is lower than the installation height of the pusher plate 500. The orthographic projection of the gear 510 overlaps with the orthographic projection of the pusher arm 340, so that the pusher plate 500 and the pusher arm 340 can be assembled more compactly on the mounting platform 110.

[0074] In another preferred embodiment, such as Figures 2 to 6 As shown, the first step 140 has a first sidewall 141 that connects to the second step 150. The first sidewall 141 forms a second limiting groove 180 around the first mounting hole 120 to limit the first support flange 221.

[0075] When the stacked push motor unit 200 is assembled onto the mounting platform 110, the first support flange 221 is circumferentially positioned by the second limiting groove 180, which facilitates the assembly operation of the operator and reduces the assembly difficulty.

[0076] In another preferred embodiment, such as Figures 2 to 7 As shown, the installation platform 110 also includes a three-level step 170 on the same side as the card storage slot 101. The first-level step 140 on the installation platform 110 is higher than the third-level step 170 on the installation platform 110. The second mounting hole 130 is located in the third-level step 170. The first-level step 140 has a second sidewall 142 connecting the third-level step 170. The second sidewall 142 circumferentially surrounds the second mounting hole 130 to form a third limiting groove 190 that limits the second support flange 410.

[0077] When the pusher motor 400 is assembled onto the mounting platform 110, the second support flange 410 is circumferentially positioned by the third limiting groove 190, which facilitates the assembly operation of the operator and reduces the assembly difficulty.

[0078] In one embodiment, such as Figure 3 , Figure 9As shown, based on all the aforementioned embodiments, the first mounting hole 120 is provided with a positioning groove 122 on the hole wall, and the first support flange 221 is provided with a positioning rib 222 that positions and cooperates with the positioning groove 122, so that the stacking motor unit 200 is positioned on the mounting platform 110.

[0079] In this embodiment, the positioning groove 122 includes a first positioning groove 1221 and a second positioning groove 1222. The lower surface of the first support flange 221 is provided with a positioning rib 222, which includes a first positioning rib 2221 and a second positioning rib 2222. The first positioning rib 2221 is positioned and fitted in the first positioning groove 1221, and the second positioning rib 2222 is positioned and fitted in the second positioning groove 1222, so that the stacking motor unit 200 is positioned on the mounting platform 110.

[0080] The positioning groove and positioning rib work together to enable the stacking motor unit 200 to be more accurately positioned and assembled onto the mounting platform 110, which helps to improve the assembly accuracy of the stacking motor unit 200 and the matching accuracy between the stacking motor unit 200 and the stacking assembly 300.

[0081] In one embodiment, such as Figures 1 to 7 As shown, based on all the aforementioned embodiments, the card storage bracket 100 also includes a hollow structure 102 surrounding the outside of the mounting platform 110 and connecting the two ends of the card storage slot 101. The hollow structure 102 extends into the inside of the mounting platform 110 to form a first mounting hole 120.

[0082] The hollow structure 102 on the storage bracket 100 extends into the mounting platform 110 to form a first mounting hole 120, which avoids interference between the hole wall of the first mounting hole 120 and the stacking operation of the stacking component 300.

[0083] In one embodiment, based on all the foregoing embodiments, such as Figure 2 , Figure 3 , Figure 6 , Figure 8 As shown, the stacking and pushing assembly 300 includes a card-bearing wheel 310, a card-bearing swing rod 330, and a card-bearing seat 320. The stacking and pushing motor unit 200 includes a stacking and pushing motor body 210 with a motor shaft 211 and a motor base 220 for mounting the stacking and pushing motor body 210. A first support flange 221 is disposed on the motor base 220. The card-bearing seat 320 and the card-bearing swing rod 330 are mounted on the motor base 220. A guide seat 223 for guiding the lifting direction of the card-bearing seat 320 is protruding on the motor base 220. The card-bearing wheel 310 is mounted on the motor shaft 211, so that the card-bearing wheel 310, the card-bearing swing rod 330, the card-bearing seat 320, and the stacking and pushing motor unit 200 are assembled into a whole and then installed on the mounting platform 110.

[0084] The card holder 320 is provided with a guide member 321, and the guide seat 223 is provided with a guide groove to guide the lifting direction of the guide member 321. The stacking and pushing assembly 300 also includes a card pushing swing rod 340. After the card holder wheel 310, the card holder swing rod 330, the card holder 320 and the stacking and pushing motor unit 200 are assembled into a whole and installed on the installation platform 110, the card pushing swing rod 340 is located above the card holder 320 and the card holder wheel 310.

[0085] Since the bearing wheel 310, bearing swing arm 330, bearing seat 320, stacking motor body 210 and motor seat 220 are all small parts, it is relatively easy to assemble multiple small parts into a whole; and since the installation and operation space provided on the installation platform 110 for the stacking assembly 300 and stacking motor unit 200 is limited, assembling the bearing wheel 310, bearing swing arm 330, bearing seat 320 and stacking motor unit 200 into a whole and installing them on the installation platform 110 can greatly reduce the operational difficulty of assembling the stacking assembly 300 and stacking motor unit 200 on the installation platform 110.

[0086] In this preferred embodiment, the bearing swing arm 330 swings up and down relative to the motor base 220, and the hole wall on one side of the first mounting hole 120 is provided with a relief groove 121 to avoid the bearing swing arm 330.

[0087] The card-bearing swing arm 330 is used to drive the card-bearing seat 320 to move up and down, so that the card-bearing seat 320 can complete the stacking action. The stacking and pushing assembly 300 also includes a card-bearing wheel 310, and the side of the card-bearing wheel 310 is provided with a card-bearing curved groove 311. The card-bearing swing arm 330 is provided with a second transmission pin supported on the card-bearing curved groove 311. The rotation of the card-bearing wheel 310 causes the card-bearing curved groove 311 to drive the second transmission pin to move up and down, so that the card-bearing swing arm 330 swings up and down. The up and down swing of the card-bearing swing arm 330 drives the card-bearing seat 320 to move up and down.

[0088] The wall of the first mounting hole 120 is provided with a clearance groove 121 to avoid interference between the movement of the pendant swing rod 330 and the wall of the first mounting hole 120.

[0089] This utility model also proposes an automatic mahjong machine with tilted card-feeding, which adopts the tilted card-feeding device of any of the aforementioned embodiments.
