Description

Technical Field

[0001] The invention belongs to the technical field of automatic mahjong machines and relates to a card shuffling plate device in a mahjong machine. Background Art

[0002] The existing mahjong machine shuffling device, such as Figure 1 As shown, it includes a shuffling turntable 1, a card-turning bar device 2, a central shaft seat 4, and a plurality of card-turning magnet blocks 3 arranged below the edge area of ​​the shuffling turntable. When the shuffling turntable 1 rotates, the area where the edge of the shuffling turntable sweeps the magnetic field of the card-turning magnet block 3 is the annular card-turning card-loading area 11, and the area in the middle of the shuffling turntable that cannot sweep the magnetic field of the card-turning magnet block 3 is the central card-storing area 12, that is, the annular card-turning card-loading area 11 is connected to the outer ring edge of the central card-storing area 12. The card-turning bar device 2 is arranged on the shuffling turntable, and the card-turning bar device includes a card-turning bar seat 21 and a plurality of card-turning bars 22. The card-turning bar device is mounted on the central shaft seat 4 through the card-turning bar seat 21, and each card-turning bar 22 extends from the card-turning bar seat 21 to the edge of the card-turning magnet block 3 in a left-handed (left-handed spiral) or right-handed (right-handed spiral). When the shuffle turntable rotates counterclockwise to turn over the cards, the card-digging strip 22 is a left-handed left-handed spiral line extending out of the card-digging strip seat; when the shuffle turntable rotates clockwise to turn over the cards, the card-digging strip 22 is a right-handed right-handed spiral line extending out of the card-digging strip seat. The tails of multiple card-digging strips form a card-sweeping range in a circumferential state around the card-digging strip seat, and the lower edge of the circumferential card-sweeping range overlaps with the edge of the card-flipping magnet block 3 to ensure that the mahjong tiles in the central card-storing area 12 in the middle of the shuffle turntable can directly enter the magnetic field area of ​​the card-flipping magnet block 3 according to the card-digging strip when the shuffle turntable rotates around the central axis seat 4, or the mahjong tiles in the central card-storing area 12 are first squeezed into the edge of the large plate, and then driven by the tendon sheet at the edge of the large plate, the mahjong tiles pass through the card-coming edge line of the card-flipping magnet block 3, and then reach the magnetic field area of ​​the card-flipping magnet block 3; as the shuffle turntable rotates, the mahjong tiles in the annular card-flipping area all pass over the card-flipping magnet block 3 to perform a card-flipping action using the magnetic repulsion principle.

[0003] As the mahjong tiles become larger, the interior of the shuffling plate becomes more and more crowded. Under the strong card-swiping action of the card-swiping bar device, the annular card-flipping and card-loading area becomes more crowded into a card pile state. At this time, the card-flipping and edge-pulling functions of the card-flipping magnet block 3 affect each other, ultimately resulting in a significant reduction in the card-flipping efficiency, edge-pulling effect and card-loading efficiency. The shuffling time of a mahjong machine with larger mahjong tiles is longer and longer than that of a mahjong machine with smaller mahjong tiles.

[0004] Secondly, during the card sorting process, the tail end of the card shifting bar device will be repeatedly and intermittently subjected to the thrust generated by the crowded mahjong tiles, and the card shifting bar 22 will change between two states: elastic deformation of the bar body and restoration of the bar body to its original state, thereby generating a large card-stirring noise. Once the card shifting bar 22 reaches its deformation limit, the bar body will break, causing the mahjong machine to be unable to complete the card sorting.

[0005] Secondly, in order to ensure that all mahjong tiles can approach the flip magnet block, the flip bar 22 of the flip bar device is installed close to the flip magnet block. The flip magnet block most commonly has four edge lines, the outer edge line 312 close to the edge of the shuffle turntable, and the inner edge line 314 away from the edge of the shuffle turntable. When the mahjong tiles enter the magnetic field range of the flip magnet block, they first cross the card edge line 311, and when they leave the magnetic field range of the flip magnet block after completing the flip, they cross the card edge line 313. When the mahjong tiles follow the card-digging strip and detach from the tail end of the card-digging strip, they can smoothly cross the incoming card edge line 311 of the flipping magnet block driven by the tendon piece at the edge of the large plate, the card-digging strip 22 and the incoming card edge line 311 transmit the mahjong tiles state without dead angles; when the mahjong tiles follow the card-digging strip and detach from the tail end of the card-digging strip, they are blocked by the magnetism of the inner edge line 314 and cannot approach the tendon piece at the edge of the large plate, nor can they smoothly enter the magnetic field range of the flipping magnet block. When flipping the tiles, the magnetism of the flipping magnet block and the magnetism of the mahjong tiles can easily form a static balance under the magnetic obstruction of the inner edge line 314, and the shuffling cannot be completed. It can be seen that the disadvantage of this installation method is that it is very easy to produce dead points of the shuffling turntable and the flipping dead points.

[0006] To sum up, under the above-mentioned design and installation conditions, the card dialing bar device and the flipping magnet block cannot simultaneously take into account the five functions of dialing, stirring cards, flipping cards, pulling edges and preventing dead points of shuffling the card plate. This is an important reason why the card dialing bar of the shuffling card plate device is easy to break, the card dialing bar stirs cards with loud noise, the flipping magnet block has low flipping efficiency and low card loading efficiency. At the same time, the installation method in which the tail end of the card dialing bar device is relatively close to the flipping magnet block is very likely to produce dead points of the shuffling card plate and flipping dead points. Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide a magnetic card shuffling plate device for a mahjong machine, so as to improve the efficiency of turning over cards, the edge pulling effect and the card loading efficiency, and there is no dead point of shuffling, no dead point of turning over cards, no failure of breaking the card shuffling bar and low card stirring noise, which is conducive to sorting large cards and more mahjong tiles, and is conducive to improving product quality and achieving a silent card sorting effect.

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] A magnetic card shuffling disk device for a mahjong machine comprises a shuffling turntable, a central shaft seat and a plurality of card flipping magnet blocks arranged below the edge area of ​​the shuffling turntable. The shuffling turntable is mounted on the central shaft seat and rotates. The device is characterized in that a card flipping magnet bar located inside the card flipping magnet block is also arranged below the shuffling turntable.

[0010] The present invention eliminates the need for a card-digging bar device, and adds a card-digging magnet bar arranged on the inner side of the flipping magnet block, so that the card-digging magnet bar has the functions of dipping and pulling cards and flipping cards. The card-dipping and pulling function dips and pulls mahjong tiles to the top of the flipping magnet block to flip the tiles. At the same time, the card-dipping magnet bar is also responsible for flipping tiles and avoiding dead corners of the large-scale shuffling plate, and the flipping magnet block is responsible for flipping tiles and pulling edges, that is, the five functions of dipping tiles, stirring tiles, flipping tiles, pulling edges and preventing dead corners of the large-scale shuffling plate can be taken into account at the same time, and the flipping efficiency is high while the edge pulling effect is good. After the mahjong tiles are flipped, the position of the mahjong tiles is conducive to improving the card-loading efficiency of the card suction wheel; the application scheme has no dead corners because the magnetic card-dipping shuffling plate has no dead corners, does not need to use cow tendon bars and card-dipping bar devices to assist in shuffling, does not have the fault of breaking the card-dipping bar, and has low card-digging noise, which is conducive to sorting large tiles and a large number of mahjong tiles, and is conducive to improving product quality and achieving a silent card sorting effect.

[0011] In a preferred embodiment, the card-pulling magnet strip is close to the vertex where the inner edge line of the flipping magnet block and the edge line of the incoming card meet. In this way, the mahjong tiles can be more easily pulled to the inner middle area of ​​the flipping magnet block under the guidance of the card-pulling magnet strip, thereby improving the card pulling effect.

[0012] In one embodiment of the present invention, the magnetic field sweeping area of ​​the card-moving magnet bar and the card-flipping magnet block completely covers the card-receiving area on the shuffling turntable.

[0013] In another embodiment of the present invention, the shuffling turntable is preferably a flat circular disc shuffling turntable, and the upper surface of the central card storage area of ​​the flat circular disc shuffling turntable is a flat circular disc.

[0014] In another embodiment of the present invention, the card-shifting magnet strip is composed of a plurality of card-shifting magnet blocks, and the distance between any two adjacent card-shifting magnet blocks is less than or equal to the minimum length of the face of the shuffled mahjong tiles, otherwise the mahjong tiles may slip away from between the two magnet blocks, preferably less than or equal to 1 cm.

[0015] The card flipping magnet blocks are distributed at equal intervals in the edge area of ​​the magnetic card flipping and shuffling plate, and the card flipping magnet strips are arranged obliquely relative to the card flipping magnet blocks.

[0016] The distance between the card-pulling magnet strip and the card-flipping magnet block is less than or equal to the minimum length of the shuffled mahjong tiles, otherwise the mahjong tiles may slip away from between the two magnet blocks, preferably less than or equal to 1 cm.

[0017] The width of the upper surface of the card flipping magnet strip is equal to or slightly larger than the width of the upper surface of the shuffled cards, otherwise the card flipping efficiency will be reduced.

[0018] Therefore, by adopting the above technical scheme, the magnetic card shuffling plate device of the mahjong machine of the present invention has the advantages of improving the efficiency of turning over cards, the edge pulling effect and the card loading efficiency, and has no dead point of shuffling, no dead point of turning over cards, no failure of breaking the card shuffling bar and low card stirring noise, which is beneficial for sorting large cards and more mahjong tiles, and is beneficial for improving product quality and achieving a silent card sorting effect.

[0019] In another preferred embodiment, the present invention shortens the tail end of the card dialing bar of the card dialing bar device and replaces it with a shorter non-magnetic card dialing bar, and adds a card dialing magnet bar to be arranged between the shorter non-magnetic card dialing bar and the flipping magnet block, so that the card dialing magnet bar has the functions of dialing and pulling cards and flipping cards. Its card dialing and pulling function dials the mahjong tiles to the top of the flipping magnet block to flip the cards. At the same time, the card dialing magnet bar is also responsible for flipping cards and avoiding dead corners of large-scale shuffling. The flipping magnet block is responsible for flipping cards and pulling edges, that is, the five functions of dialing cards, stirring cards, flipping cards, pulling edges and preventing dead points of large-scale shuffling can be taken into account at the same time. The flipping efficiency is high and the edge pulling effect is also good. After the mahjong tiles are flipped, the position of the mahjong tiles is conducive to improving the card loading efficiency of the card suction wheel; at the same time, the upper middle part of the shuffling turntable continues along The application scheme of using a shorter non-magnetic card-digging strip is that the magnetic card-digging shuffling plate has no dead angle, and there is no need to use cow tendon strips and card-digging strip devices to assist in shuffling. There is no failure of breaking the card-digging strip and the card-stirring noise is low. The shorter non-magnetic card-digging strip continues to be responsible for sweeping the mahjong tiles above the middle of the shuffling turntable, sweeping the mahjong tiles to the range that the card-digging magnet strip can sweep, and the card-digging magnet strip continues to be responsible for sweeping the mahjong tiles to the range that the flipping magnet block can sweep, that is, the sweeping area of ​​the non-magnetic card-digging strip, the magnetic field sweeping area of ​​the card-digging magnet strip and the magnetic field sweeping area of ​​the flipping magnet block completely cover the card-bearing area on the shuffling turntable, which is beneficial to sorting out medium and crowded large, medium and small mahjong tiles, and is beneficial to improving product quality and achieving a silent card sorting effect.

[0020] Furthermore, in another preferred embodiment, the card-pulling magnet bar is close to the vertex where the inner edge line of the flipping magnet block and the edge line of the incoming card meet. In this way, the mahjong tiles can be more easily pulled to the inner middle area of ​​the flipping magnet block under the guidance of the card-pulling magnet bar, thereby improving the card pulling effect.

[0021] In another embodiment of the present invention, the shuffling turntable is a circular shuffling turntable with a convex middle and flat surroundings, and the upper surface of the central card storage area of ​​the circular shuffling turntable is a circular convex middle disk; or the shuffling turntable is a flat circular shuffling turntable, and the upper surface of the central card storage area of ​​the flat circular shuffling turntable is a flat circular disk.

[0022] The spacing between the card-pulling magnet strip and the card-flipping magnet block is less than or equal to the minimum length of the shuffled mahjong tiles, otherwise the mahjong tiles may slip away from between the two magnet blocks, preferably less than or equal to 1 cm. The spacing between the card-pulling magnet strip and the card-flipping magnet block is less than or equal to the minimum length of the shuffled mahjong tiles, otherwise the mahjong tiles may not enter the magnetic field sweeping area of ​​the card-pulling magnet strip, preferably less than or equal to 1 cm.

[0023] The width of the upper surface of the card flipping magnet strip is equal to or slightly larger than the width of the upper surface of the shuffled cards, otherwise the card flipping efficiency will be reduced.

[0024] When the card-moving magnet strip 31 is shortened to a certain length, it is equivalent to a card-moving magnet block 300 . BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Example 1

[0042] like Figure 2 and Figure 3 As shown, the magnetic card shuffling disk device of the mahjong machine of this embodiment includes a shuffling turntable 1, a central shaft seat 4 and a plurality of card flipping magnet blocks 3 arranged below the edge area of ​​the shuffling turntable, and also includes a card flipping magnet bar 31 arranged below the center of the shuffling turntable.

[0043] The shuffling turntable 1 is a conical disk with a high center and low sides. In this embodiment, the shuffling turntable 1 rotates counterclockwise under the drive of a motor. During rotation, the area where the edge of the shuffling turntable sweeps the magnetic field of the flipping magnet block 3 is the annular flipping card area 11 (i.e., the flipping magnet block magnetic field sweeping area 333), and the area where the middle of the shuffling turntable sweeps the magnetic field of the dialing magnet strip 31 (i.e., the dialing magnet strip magnetic field sweeping area 388) is the central card storage area 12, that is, the annular flipping card area 11 is connected to the outer ring edge of the central card storage area 12.

[0044] The flipping magnet block 3 has an incoming card edge line 311 , an outer edge line 312 , a leaving card edge line 313 and an inner edge line 314 ; the flipping magnet bar 31 has an incoming card edge line 3101 , an outer edge line 3102 , a leaving card edge line 3103 and an inner edge line 3104 .

[0045] In this embodiment, the card-swiping magnet strip 31 is close to the intersection vertex of the inner edge line 314 of the card-flipping magnet block 3 and the card-incoming edge line 311. The outer edge line 312 of the card-flipping magnet block 3 is parallel or nearly parallel to the edge tangent line of the shuffle turntable 1, and the card-swiping magnet strip 31 is tilted relative to the card-flipping magnet block 3.

[0046] The spacing between the card-digging magnet strip 31 and the card-flipping magnet block 3 should be less than or equal to the minimum length of the cards of the shuffled mahjong tiles, otherwise the mahjong tiles may slip away from between the two magnet blocks, preferably less than or equal to 1 cm. In an embodiment, the intersection vertex of the incoming card edge line 3101 and the outer edge line 3102 of the card-digging magnet strip 31 is close to the intersection vertex of the inner edge line 314 and the incoming card edge line 311 of the card-flipping magnet block 3. In addition, the upper surface width of the card-digging magnet strip 31 is equal to or slightly larger than the upper surface width of the shuffled cards, otherwise the card-flipping efficiency will be reduced.

[0047] In this embodiment, the flip magnet block 3 and the dial magnet strip 31 are stationary, and only the shuffling turntable 1 rotates under the drive of the motor, so that the mahjong tiles can move toward the edge of the shuffling turntable 1.

[0048] In this embodiment, a central shaft seat pressure cover 41 is further provided above the central shaft seat 4. The central shaft seat pressure cover 41 is in the shape of a conical pagoda with a high middle and low surroundings. The lower part of the central shaft seat pressure cover 41 is pressed on the central upper surface of the shuffling turntable 1. All mahjong tiles that fall into the shuffling barrel cannot stay on the upper surface of the central shaft seat pressure cover 41, and all will fall into the annular card flipping and loading area 11 of the shuffling turntable and the card receiving area above the central card storage area 12. The magnetic field sweeping area of ​​the card flipping magnet strip 31 and the card flipping magnet block 3 completely covers the card receiving area on the above-mentioned shuffling turntable to ensure that all mahjong tiles can move toward the edge of the shuffling turntable 1 and be loaded.

[0049] The number of the card-moving magnet strips 31 is greater than or equal to 1, and two are used in this embodiment.

[0050] Example 2

[0051] like Figure 4 and Figure 5 As shown, the difference between this embodiment and the first embodiment is that the shuffling turntable of this embodiment rotates clockwise, and accordingly, the positional relationship between the flipping magnet strip 31 and the flipping magnet block 3 is opposite to that of the first embodiment. At the same time, the flipping magnet strip is composed of a plurality of flipping magnet blocks 300, and the distance between any two adjacent flipping magnet blocks 300 is less than or equal to the minimum length of the face of the shuffled mahjong tiles, otherwise the mahjong tiles may slip away from between the two magnet blocks, preferably less than or equal to 1 cm.

[0052] In this embodiment, eight card-shifting magnet blocks 300 are respectively connected to form two card-shifting magnet strips. The connected card-shifting magnet strips can be arcs or straight lines.

[0053] The other structures are the same as those in Embodiment 1 and will not be described again here.

[0054] Example 3

[0055] like Figure 6 As shown, combined with reference Figure 2 The difference between this embodiment and the first embodiment is that the shuffling turntable is a flat disc shuffling turntable, and the upper surface of the central card storage area of ​​the flat disc shuffling turntable is a flat disc. In this embodiment, the card storage space in the shuffling barrel is larger, which is more suitable for shuffling larger juggernaut cards.

[0056] The other structures are the same as those in Embodiment 1 and will not be described again.

[0057] like Figure 7 As shown, the force principle of the mahjong tiles on the shuffling turntable 1 of the present invention is as follows:

[0058] Z1-Z5 are mahjong tiles with the face up, and B1-B2 are mahjong tiles with the back side up.

[0059] Mahjong tiles Z1 and Z5 are both attracted by the magnet. Mahjong tile Z2 is still driven by the shuffling turntable and moves along the magnetic field of the card-digging magnet strip 31 above the card-digging magnet strip 31. Mahjong tile Z3 is still attracted by the flipping magnet block 3 above the card-digging magnet strip 31. Mahjong tile Z4 has been attracted by the flipping magnet block and can only wait for the tendon slice to come over to take it away from the flipping magnet block.

[0060] The backs of mahjong tiles B1-B2 are facing upward and are repelled by the magnet. Mahjong tile B1 moves back to the side under the repulsion of the card-turning magnet strip, and mahjong tile B2 moves back to the side under the repulsion of the card-flipping magnet block 3. If there are many tiles behind mahjong tile B1 pushing it, mahjong tile B1 will be squeezed onto the card-turning magnet strip 31 and flipped over. Mahjong tile B1 or mahjong tile B2 that has already moved to the side will enter the top of the card-flipping magnet block 3 and be flipped over under the drive of the tendon piece.

[0061] Through the above detailed description, it can be known that the present invention adopts a card-digging magnet strip, which is arranged on the inner side of the flipping magnet block, so that the card-digging magnet strip has the functions of dipping and pulling cards and flipping cards. Its card-dipping function pulls the mahjong tiles to the top of the flipping magnet block and flips the cards. At the same time, the card-dipping magnet strip is also responsible for flipping cards and avoiding dead corners of the large-scale shuffling. The flipping magnet block is responsible for flipping cards and pulling edges, that is, the five functions of dipping cards, stirring cards, flipping cards, pulling edges and preventing dead points of large-scale shuffling can be taken into account at the same time, and the flipping efficiency is high while the edge pulling effect is also good. After the mahjong tiles are flipped, the position of the mahjong tiles is conducive to improving the card-loading efficiency of the card suction wheel; its application scheme has no dead corners because the magnetic card-dipping shuffling plate has no dead corners, and there is no need to use cow tendon strips and card-dipping strip devices to assist in shuffling, there is no fault of breaking the card-dipping strip, and the card-digging noise is low, which is conducive to sorting large cards and sorting more mahjong tiles, and is conducive to improving product quality and achieving a silent card sorting effect.

[0062] Embodiment 4

[0063] like Figure 8 and Fig. 9 As shown, the magnetic shuffling disk device of the mahjong machine of this embodiment includes a shuffling turntable 1, a central shaft seat 4, and a plurality of flip magnet blocks 3 arranged below the edge area of ​​the shuffling turntable, and also includes a card-digging bar device 2 arranged above the middle of the shuffling turntable 1, the card-digging bar device 2 adopts a short card-digging bar 23 (i.e., a short non-magnetic card-digging bar), and a card-digging magnet bar 31 is further arranged below the center of the shuffling turntable between the tail end of the short card-digging bar 23 and the flip magnet block 3. Among them, the shuffling turntable 1 is a conical disk with a high center and low surroundings.

[0064] In this embodiment, the shuffling turntable 1 rotates counterclockwise under the drive of the motor. During the rotation, the area where the edge of the shuffling turntable sweeps the magnetic field of the flipping magnet block 3 is the annular flipping card area 11 (i.e., the flipping magnet block magnetic field sweeping area 333), and the area where the middle of the shuffling turntable sweeps the magnetic field of the dialing magnet bar 31 (i.e., the dialing magnet bar magnetic field sweeping area 388) is the outer ring edge of the central card storage area 12, that is, the annular flipping card area 11 is connected to the outer ring edge of the central card storage area 12, and the central card storage area 12 includes the dialing magnet bar magnetic field sweeping area 388 and the dialing bar sweeping area 288.

[0065] The flipping magnet block 3 has an incoming card edge line 311 , an outer edge line 312 , a leaving card edge line 313 and an inner edge line 314 ; the flipping magnet bar 31 has an incoming card edge line 3101 , an outer edge line 3102 , a leaving card edge line 3103 and an inner edge line 3104 .

[0066] In this embodiment, the card-swiping magnet strip 31 is close to the intersection vertex of the inner edge line 314 of the card-flipping magnet block 3 and the card-incoming edge line 311. The outer edge line 312 of the card-flipping magnet block 3 is parallel or nearly parallel to the edge tangent line of the shuffle turntable 1, and the card-swiping magnet strip 31 is tilted relative to the card-flipping magnet block 3.

[0067] The spacing between the card-digging magnet strip 31 and the card-flipping magnet block 3 should be less than or equal to the minimum length of the cards of the shuffled mahjong tiles, otherwise the mahjong tiles may slip away from between the two magnet blocks, preferably less than or equal to 1 cm. In an embodiment, the intersection vertex of the incoming card edge line 3101 and the outer edge line 3102 of the card-digging magnet strip 31 is close to the intersection vertex of the inner edge line 314 and the incoming card edge line 311 of the card-flipping magnet block 3. In addition, the upper surface width of the card-digging magnet strip 31 is equal to or slightly larger than the upper surface width of the shuffled cards, otherwise the card-flipping efficiency will be reduced.

[0068] In this embodiment, the card-digging magnet strip 31 is shorter than the card-digging magnet strip 31 in the first embodiment. The central circle of the shuffling plate device is responsible for sweeping the cards by the card-digging strip device 2. The card-digging strip device 2 adopts a shorter short card-digging strip 23 (i.e., a short non-magnetic card-digging strip). The mahjong cards falling into the sweeping area 288 of the short card-digging strip 23 enter the magnetic field sweeping area 388 of the card-digging magnet strip 31 after being swept by the short card-digging strip, and then enter the magnetic field sweeping area 333 of the flipping magnet block 3. Figure 8 The short card-moving strip 23 and the card-moving magnet strip 31 are shown to be connected in sequence to transfer mahjong tiles. Fig. 9 What is shown is the staggered docking of the short card-moving strip 23 and the card-moving magnet strip 31 to transfer mahjong tiles.

[0069] In this embodiment, the flip magnet block 3 and the dial magnet strip 31 are stationary, and only the shuffling turntable 1 rotates under the drive of the motor, so that the mahjong tiles can move toward the edge of the shuffling turntable 1.

[0070] In the present embodiment, a central shaft seat pressure cover 41 is further provided above the central shaft seat 4. The central shaft seat pressure cover 41 is in the shape of a conical pagoda with a high middle and low surroundings, and its lower part is pressed on the central upper surface of the shuffling turntable 1. All mahjong tiles that fall into the shuffling barrel cannot stay on the upper surface of the central shaft seat pressure cover 41, and all will fall into the annular card flipping and loading area 11 of the shuffling turntable and the card receiving area above the central card storage area 12. The sweeping area of ​​the card flipping bar 23, the card flipping magnet bar 31 and the magnetic field sweeping area of ​​the card flipping magnet block 3 completely cover the card receiving area on the above-mentioned shuffling turntable to ensure that all mahjong tiles can move toward the edge of the shuffling turntable 1 and be loaded.

[0071] The number of the card-moving magnet strips 31 is greater than or equal to 1, and this embodiment uses 4 magnet strips.

[0072] When the card-moving magnet strip 31 is shortened to a certain length, it is equivalent to a card-moving magnet block 300 .

[0073] Through the above detailed description, it can be known that the present invention shortens the tail end of the card dialing bar device and replaces it with a shorter non-magnetic card dialing bar, and adds a card dialing magnet bar to be arranged between the shorter non-magnetic card dialing bar and the card flipping magnet block, so that the card dialing magnet bar has the functions of dialing and pulling cards and flipping cards. Its card dialing and pulling function dials the mahjong tiles to the top of the card flipping magnet block to flip the cards. At the same time, the card dialing magnet bar is also responsible for flipping cards and avoiding dead corners of large-scale shuffling. The card flipping magnet block is responsible for flipping cards and pulling edges, that is, the five functions of dialing cards, stirring cards, flipping cards, pulling edges and preventing dead points of large-scale shuffling can be taken into account at the same time. The flipping efficiency is high and the edge pulling effect is also good. After the mahjong tiles are flipped, the position of the mahjong tiles is conducive to improving the card loading efficiency of the card suction wheel; at the same time, the upper middle part of the shuffling turntable continues The shorter non-magnetic card-swiping strip is still used. Its application scheme has no dead angle on the magnetic card-swiping plate, and there is no need to use cow tendon strips and card-swiping strip devices to assist in shuffling. There is no failure of breaking the card-swiping strip and the card-stirring noise is low. The shorter non-magnetic card-swiping strip continues to be responsible for sweeping the mahjong tiles above the middle of the shuffling turntable, sweeping the mahjong tiles to the range that the card-swiping magnet strip can sweep, and the card-swiping magnet strip continues to be responsible for sweeping the mahjong tiles to the range that the flipping magnet block can sweep, that is, the sweeping area of ​​the non-magnetic card-swiping strip, the magnetic field sweeping area of ​​the card-swiping magnet strip and the magnetic field sweeping area of ​​the flipping magnet block completely cover the card-bearing area on the shuffling turntable, which is conducive to sorting out medium and crowded large, medium and small mahjong tiles, and is conducive to improving product quality and achieving a silent card sorting effect.
