The rotor main gear ring continues to rotate to the waiting channel of the rotor rocker arm, where the rotor main gear ring magnet aligns with the waiting position magnetic control, completing the single-card draw. The hole cards and the remaining cards are pushed onto the table separately, separated in time and space. The remaining cards are pushed out in a shorter arrangement, which effectively makes it convenient and easy for players to draw cards in the opposite position. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Reference Figure 1-12 The present invention provides a rotary track structure and control device for a mahjong machine capable of two-way card delivery, comprising a rotor main frame, a card delivery compartment door assembly 8, a rotary card loading assembly, a card incoming magnetic control assembly, and a control system; the rotor main frame is provided with a card supply port 1, a card delivery track 6, and a rotor rocker arm waiting channel 2; the card delivery compartment door assembly 8 comprises a card delivery compartment door 14, a card delivery compartment door mounting frame 13, a compartment door bracket 16, and a compartment door rocker arm 15; the rotary card loading assembly comprises a rotor main wheel The gear disc 19, the rotor rocker arm 21, the rotary push motor 33, the drive gear 32, the rotor main shaft 34, the incoming card magnetic control assembly includes the incoming card magnetic control 24, the incoming card magnetic control frame 25, and the incoming card pendulum 23; the card supply port 1 is located at the input end of the card track 6, the rotor rocker arm waiting channel 2 is located outside the card supply port 1, the card discharge door mounting frame 13 is located on one side of the card discharge door 14, and the door bracket 16 is located in the middle of the bottom of the card discharge door 14. The intermediate position, the warehouse door rocker arm 15 is installed on the warehouse door bracket 16, the rotor rocker arm 21 is located on the rotor main gear tooth plate 19, the driving gear 32 is installed on the rotary push motor 33, and the rotor main gear tooth plate 19 is installed on the rotor main shaft 34. The rotor main frame is provided with a desktop magnetic control slot 7, a track magnetic control 4, a bottom card positioning magnetic control slot 5, a push card positioning and waiting position magnetic control slot 3, the desktop magnetic control slot 7 is located on the rotor main frame, the track magnetic control 4 and the bottom card positioning magnetic control slot 5 are located on the inner side of the card walking track 6, the push card positioning and waiting position magnetic control slot 3 is located at the output end of the card walking track 6, the card output warehouse door 14 is provided with a warehouse door motor side bracket 11, and the warehouse door motor 12 and the warehouse door rocker arm magnetic control 18 are installed on the warehouse door motor side bracket 11. The control system includes desktop magnetic control, track magnetic control 4, bottom card positioning magnetic control, push card positioning magnetic control, waiting position magnetic control 9 and PC control motherboard.

[0031] As can be understood, the present device receives cards through the card opening (the card is picked up by the card suction wheel of the mahjong machine, transported to the delivery outlet by the conveyor belt and falls on the card receiving seat of the stacking machine head. The card receiving seat sinks one card position after the first card falls, and the second card is delivered to the push head and pushed to the card track 6, advancing the corresponding number of piles according to the set number of playing cards.) Taking the 144-card game with 36 cards and 18 piles on one side as an example, the lower stacking machine head has stacked 2 mahjong tiles and the push head pushes them to the card track 6. After pushing 18 piles of cards, the push head returns to the side of the card track 6 to block the delivery outlet to achieve unilateral reset. The card track 6 is filled with 18 piles starting from the card supply opening 1, and the rotary push motor 33 drives the rotor main gear sprocket 19 to rotate from the waiting position through the drive gear 32. The front end of the rotor main gear sprocket 19 has a rotor rocker arm 21 whose position and length can be adjusted according to the size of the cards. The joint of the rotor rocker arm 21 and the rotor main gear sprocket 19 has a magnet mounting column 20. With the rotor main shaft 34 as the center, the push card positioning magnetic control, waiting position magnetic control 9 and bottom card positioning magnetic control installed on the rotor main frame are all on the same circumference. The magnet at the connection between the rotor main gear disc 19 and the rotor rocker arm 21 gives magnetic signals to these three magnetic control points. If the rotor main gear disc 19 starts to rotate from the waiting position to push the 18 piles of cards toward the card track 6 in a counterclockwise direction, the card output door motor 12 rotates to lower the card output door 14 near the end of the card track 6 to open the card output port. The rotor main gear disc 19 rotates the rotor rocker arm 21 to push all the cards out of the card output door 14. The magnet of the rotor main gear disc 19 just corresponds to the push card positioning magnetic control rotor main gear disc 19 and stops. The motor drives to lift the card output door 14 near the end of the card track 6 to close the card output port. The rotor main gear sprocket 19 continues to rotate to the rotor rocker arm waiting channel 2, and the magnet of the rotor main gear sprocket 19 corresponds exactly to the waiting position magnetic control 9, completing the entire unilateral card play.

[0032] When the player avoids drawing the hole cards, let's take a game with 18 single-handed tricks and 36 cards, totaling 144 cards, as an example. The stacking mechanism below the rotor mainframe's card inlet 1 pushes incoming cards, in stacks of two, onto the card track 6. After pushing all six tricks (12 cards can be preset for different hole card counts on the PC control motherboard), the rotary push motor 33, via the drive gear 32, drives the rotor main gear sprocket 19 from its waiting position. The rotor main gear sprocket 19 rotates the rotor rocker 21, pushing the six hole cards counterclockwise onto the card track 6, stopping near the card exit door 14. A safe distance should be left between the first trick and the end of the card track 6. If the cards are too close to the card exit door 14, interference will occur when the door opens and closes.

[0033] The position and method of the sensing point for holding the bottom card can be realized in two modes on this structural device. Mode A is that the magnet of the rotor main gear sprocket 19 stops at the bottom card positioning magnetic control, and the size of the connection position from here to the card track 6 and the card outlet door 14 is 6 piles + safety distance. Mode B is a position that can adapt to a variety of bottom cards such as 6 piles of 12 cards, 6.5 piles of 13 cards, and 8 piles of 16 cards. In this method, after the stacking machine head pushes the corresponding number of cards into the card track 6 according to the shuffling procedure, the rotary push motor 33 drives the rotor main gear sprocket 19 to rotate from the waiting position through the drive gear 32, and the rotor main gear sprocket 19 rotates the rotor rocker arm 21 to push the corresponding bottom card counterclockwise to the card track 6 near the card outlet door 14 and stop. At this time, the stop sensing position is 1 pile + safety distance back (clockwise) from the connection position of the card-moving track 6 and the card-discharging door 14. A track magnetic control 4 is provided at the bottom of the card-moving track 6. The magnet in the lower layer of cards with the first pile facing down sends an induction signal to the track magnetic control 4. The track magnetic control 4 receives the signal and the rotation push motor 33 is instructed by the PC control motherboard to stop the rotor main gear disc 19 and rotate the rotor rocker arm 21 to stop behind the last pile of bottom cards.

[0034] When the two card-handling methods are used, the main rotor gear 19 rotates the rotor rocker arm 21 to push the bottom card toward the end of the card track 6. The conveyor and stacking heads simultaneously stop shuffling. The main rotor gear 19 rotates the rotor rocker arm 21, leaving the card inlet 1 and entering the card track 6, opening the stacking head. The conveyor and stacking heads continue to shuffle the cards, and the stacking head stacks the remaining cards onto the card track 6. Each party sets a number of cards, and after removing the bottom card, all the remaining cards are stacked and pushed onto the card track 6. The stacking head closes and stops at the entrance of the card track 6. At this point, all cards corresponding to each party have entered the card track 6, with the rotor rocker arm 21 positioned between the bottom card and the remaining cards. All four parties have shuffled their cards, and the entire machine is reset.

[0035] When a player wins a hand on the table, the game ends. The dealer presses the lift button to raise the central control panel (dice tray) and push all the tiles onto the table into the shuffler. The player presses the lift button again, lowering the card drawer door 14 to the end of the card track 6. The rotor main gear sprocket 19 rotates the rotor rocker arm 21, pushing the corresponding bottom card counterclockwise onto the card track 6 near the card drawer door 14. The magnet on the rotor main gear sprocket 19 generates a push-card positioning magnetic control signal, causing the rotor rocker arm 21 to stop. The card drawer door 14 then raises to the end of the card track 6, lifting the bottom card onto the table. In Mode A, the rotor main gear sprocket 19 continues to rotate, generating a waiting position magnetic control signal 9. The rotor main gear sprocket 19 and rotor rocker arm 21 stop in the rotor rocker arm waiting channel 2, leaving the remaining tiles within the card track 6. In mode B, the rotor main gear sprocket 19 continues to rotate to push the remaining mahjong tiles to the end of the card track 6. The first pile of mahjong tiles magnet signal is given to the track magnetic control 4, and the rotor rocker arm 21 stops behind the last pile of remaining tiles on the card track 6.

[0036] Each player moves the bottom card toward his or her side to the bottom card sorting area. When the bottom card moves toward the player, it will pass through the table's magnetic induction control. Because the bottom card is face down, the magnet in the mahjong tile sends an induction magnetic control signal to the table. The card-discharging door 14 is lowered again, and the rotor main gear sprocket 19 rotates the rotor rocker arm 21 to push all the remaining mahjong tiles to the card-discharging door 14 and the table. The card-discharging door 14 is raised, and the remaining cards to be drawn by each party are all placed on the table in front of the player in a slanted state with four sides intersecting.

[0037] A mahjong machine with a double-dispensing mahjong system featuring a rotary push track structure and control device features a unique incoming card magnetic control assembly that uses a card pendulum 23 to generate incoming card signals. This makes it particularly stable and reliable for rotary push track mahjong machines. The card inlet 1 of a rotary push track structure is relatively fixed, limiting its adjustable distance. Traditional optical sensing can be affected by factors such as dirty cards, the distance of incoming cards, and the height of incoming cards, which can affect operational stability and reliability. Frequent adjustment of the optical control itself is also required. The incoming card magnetic control assembly completely resolves these technical issues, providing safe, reliable, and stable incoming card sensing.

[0038] A rotary track structure and control device for a double-dispensing mahjong machine provides mahjong players with multiple gameplay options. Players can play a single card and draw the bottom card in the conventional way (two piles of four cards, three rounds of 12 cards, plus one card for each side to draw, totaling 13 bottom cards). Alternatively, players can play the bottom card first, move to the sorting area, and then play the remaining cards. The remaining cards continue to be played while the player sorts the bottom cards, thus avoiding the drawback of the slow and lingering nature of rotary-dispensing mahjong machines.

[0039] A rotary track structure and control device for a mahjong machine capable of two card draws has two bottom card control modes, A and B, which can be used to fix the number of bottom card piles or to set the number of bottom card piles without limit, and has stronger adaptability, compatibility and reliability.

[0040] A mahjong machine with a double-card-playing rotary track structure and a control device with a unique desktop sensing position method eliminates the possibility of interference between the bottom cards and the remaining cards during or before they are removed. It has higher safety and reliability and a better human-computer interaction experience. The rotary-push track-type card arrangement positions are already intersecting and placed diagonally, so there is no need to push the cards, and there is no need to grab the bottom cards three times in a row in one move. This structure and control device do not add any mechanical components except for a limited number of sensing points.

[0041] In one embodiment, a horizontal bar circular shaft 26 is provided above the Lai Pai pendulum 23, and a limiting boss 28 is provided forward on the upper middle part of the horizontal bar circular shaft 26, and a vertical connecting plate 29 is provided below the horizontal bar circular shaft 26. A counterweight horizontal cylinder 30 is provided at the lower rear of the vertical connecting plate 29. The counterweight horizontal cylinder 30 is a hollow cylindrical hole, and a magnet mounting hole 27 is provided at one end of the counterweight horizontal cylinder 30 on the right side near the Lai Pai magnetic control 24. The magnet mounting hole 27 is connected to the left counterweight horizontal cylinder 30, and a counterweight iron shaft 31 is provided on the left side of the counterweight horizontal cylinder 30. The depth of the magnet mounting hole 27 is adapted to the magnet diameter being larger than the counterweight horizontal cylinder 30.

[0042] As you can understand, the upper portion of the Laipai pendulum 23 of the Laipai magnetic control assembly has a horizontal bar circular shaft 26 for flexible swinging of the pendulum. The middle portion of the horizontal bar circular shaft 26 has a forward-facing limiting protrusion 28 that can limit the pendulum's backward movement beyond the magnetic control range. A vertical connecting plate 29 is provided below the horizontal bar circular shaft 26 of the Laipai pendulum 23. A counterweight horizontal cylinder 30 is provided at the rear portion of the lower portion of the vertical connecting plate 29 in the form of a hollow cylindrical hole. The right side of the counterweight horizontal cylinder 30, near the end of the Laipai magnetic control 24, is a magnet mounting hole 27 leading to the left counterweight through-hole. The depth of the magnet mounting hole 27 is adapted to ensure that the magnet diameter is larger than the counterweight through-hole. This design ensures that the magnet is embedded in the right position to ensure that the magnet is large and has strong magnetic properties. It can also attract the counterweight iron shaft 31 or screw embedded on the left without the need for threads, adhesives, or other methods to fix the counterweight so that it will not fall out.

[0043] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
