Description

Technical Field

[0001] The utility model relates to the technical field of mahjong machines, in particular to a mahjong machine with tiles loaded on a rotary push track. Background Art

[0002] Mahjong machines are used to automatically sort, stack, and advance tiles, and are commonly used in mahjong games. They save time, reduce manual sorting, stacking, and placement, and ensure fairness during the game.

[0003] The four corners of the mahjong machine feature a counterclockwise, spiral-shaped rotor track pushing mechanism. The card-discharging end of this mechanism is mounted above the four-sided card-collecting conveyor and stacking mechanism. A rotor frame bracket, attached to the baseplate, supports the rotor frame below the curved section of the track. The combined forces of the shuffling plate and scraper push the tiles around the shuffling plate. The four-sided card-collecting conveyor mechanism simultaneously uses a motor-driven card-suction wheel, which drives a belt in the opposite direction to pull the tiles upward. Magnets on the card-suction wheel attract the tiles and draw them into the conveyor chute. The belt then rotates, carrying them to the discharge port, where the belt drives the discharge wheel to deliver the tiles.

[0004] In the existing technology, the rotary push structure is complex, the force is large, and the motor requirements are high; the card discharge door corresponds to a single card width, and the rotary push rocker arm corresponds to a single card type; the rotary push card ejection is slow, etc. Therefore, a rotary push track card loading mahjong machine is provided to solve the above problems. Utility Model Content

[0005] The utility model proposes a mahjong machine with a rotary push track for loading cards, aiming to solve the problems existing in the prior art, such as a complex rotary push structure, high stress, and high motor requirements; a card discharge door corresponding to a single card width, a rotary push rocker arm corresponding to a single card type; and slow rotary ejection of cards.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a rotary push track card loading mahjong machine, comprising a shuffling plate, a card picking conveyor, a card stacking machine head, a rotary push card loading assembly, a card discharge door and a card delivery outlet; the rotary push card loading assembly comprises a rotary push motor, a driving gear, a rotor main wheel gear plate, a rotor main shaft and a rotor main frame; the card picking conveyor is located around the shuffling plate, the card stacking machine head is located on one side of the card picking conveyor, the rotary push card loading assembly is located at the four corners of the mahjong machine, the card discharge door is located on one side of the card picking conveyor, and the card delivery outlet is located at the output end of the rotary push card loading assembly.

[0007] Preferably, the card discharging door includes a card discharging door mounting seat, a door bracket and a door rocker arm, the card discharging door mounting seat is rotatably mounted on the front end of the card discharging door, the door bracket is fixedly mounted on the middle part of the card discharging door, and the door rocker arm is rotatably mounted on the door bracket.

[0008] Preferably, a door motor side bracket is provided on the card discharging door, and a door magnetic control seat is installed on the door motor side bracket.

[0009] Preferably, the thickness of the side bracket of the door motor matches the width of the card.

[0010] Preferably, a door limiting rib is provided on the bottom surface of the rotor main frame below the card discharging door.

[0011] Preferably, the track of the rotor main frame is provided with an inner ring, an outer ring and a bottom rail, and the inner ring, outer ring and bottom rail are all made of plastic with self-lubricating properties.

[0012] Preferably, a rotor rocker arm is provided on the outer side of the rotor main gear disc, and the rotor rocker arm is embedded and combined with the rotor main gear disc via a slot.

[0013] The present invention includes a shuffling tray, a card picking conveyor, a card stacking machine head, a rotary card loading assembly, a card discharging door, and a card discharging outlet; the rotary card loading assembly includes a rotary motor, a driving gear, a rotor main gear disc, a rotor main shaft, and a rotor main frame; the card picking conveyor is located around the shuffling tray, the card stacking machine head is located on one side of the card picking conveyor, the rotary card loading assembly is located at the four corners of the mahjong machine, the card discharging door is located on one side of the card picking conveyor, and the card discharging outlet is located at the output end of the rotary card loading assembly. The three contact surfaces of the rotor main frame track in the present invention are divided into an inner ring, an outer ring, and a bottom rail, all of which are made of plastic with self-lubricating properties to ensure that the strips are subjected to little force and slide smoothly when moving in a circular arc in the track. The diameter of the inner ring increases on the outside, and the track card type becomes smaller, and the diameter of the inner ring decreases on the outside, and the track card type becomes larger. Different card types have different inner rings. The card inlet end of the base track has a low outer slope and a high inner slope, facilitating smooth and stable card delivery from the card stacker's card holder into the rotor frame track. The card outlet end of the base track has a low inner slope and a high outer slope, aligned with the card outlet door when it reaches its lowest point. The height of the slope varies depending on the thickness of the cards, facilitating smooth and stable card delivery. To ensure this level of alignment, the card outlet door is fitted with two retaining ribs on the underside of the rotor frame below the bottom of the door. These ribs adjust to the thickness of the cards. To accommodate the varying widths of the cards being drawn, the door width and the thickness of the door motor bracket are matched to the card width. A magnetic control mount on the inner side of the door bracket, coupled with the rotation of the door motor, drives the door arm within the door bracket track. Clockwise rotation lowers the door to open the door for card delivery, while counterclockwise rotation raises the door to close the door for card delivery. The door bracket is fixed to the door with 2 screws. Loosening the screws and adding or removing shims can fine-tune the flatness of the door and the panel, making it easier to assemble and disassemble the structure of the card-pushing device in the track and running smoothly and reliably.

The track of the rotor main frame 45 is provided with an inner ring 412, an outer ring 413 and a bottom rail 414, and the inner ring 412, the outer ring 413 and the bottom rail 414 are all made of plastic with self-lubricating properties. A rotor rocker arm 415 is provided on the outer side of the rotor main wheel gear disc 43, and the rotor rocker arm 415 is embedded in the rotor main wheel gear disc 43 by a slot.

[0025] It can be understood that a track inner rotating push card mahjong machine, with the dice plate rising and falling as the mahjong machine shuffling barrel door, with the dice plate as the center and the dice plate below the shuffling plate 1; the four sides of the circular shuffling plate 1 are tangent to a four-sided card picking conveyor 2, and the outer side of the four-sided card picking conveyor 2 is perpendicular to the conveyor at 90 degrees to the stacking machine head 3; the four corners of the mahjong machine are provided with a counterclockwise rotating spiral rotor track pushing card structure device, the card output end of the device is mounted on the upper part of the four-sided card picking conveyor 2 and the stacking machine 3 head, and a rotor main frame 45 is provided under the arc bend of the track, and the bracket is connected to the bottom plate to support the rotor main frame 45. When the cards are pushed into the shuffling barrel and the dice plate is lowered, the shuffling plate 1 rotates in a clockwise direction, and the mahjong tiles are pushed to the four sides of the shuffling plate 1 by the combined action of the shuffling plate 1, the scraper, etc.; the four-way card picking conveyor 2 is synchronously driven by the motor to drive the card suction wheel to drive the belt in the opposite direction to move the mahjong tiles upward, which are attracted by the magnet on the card suction wheel and rolled into the conveyor trough. The belt rotates to bring the mahjong tiles to the card outlet, and the card outlet wheel is linked to the belt to send the mahjong tiles out, and the mahjong tiles fall onto the card receiving seat of the stacking machine head 3. The stacking machine head is driven by the motor to complete the action of lowering the card receiving seat, stacking two mahjong tiles and pushing a pile of cards to the rotor track mouth. The continuous action of the motor can achieve the effect of stacking and pushing cards. Continuous action; when the number of mahjong tiles in the track reaches the required setting, the push head of the stacking machine head 3 is pushed to the track mouth to close the conveying port, and the push head closes the conveying port. At the same time, the rotary push motor 41 drives the gear 42 to drive the rotor main wheel gear plate 43 to rotate counterclockwise, and the rotor rocker arm 415 and the rotor main wheel gear plate 43 are embedded in the groove. The rotor rocker arm 415 is driven by the rotor main wheel gear plate 43 to push the row of strips in the track to rotate; the rotor main frame 45 is connected to the card outlet door 5 at the end of the track card outlet through a small shaft and the card outlet door mounting seat 47, and a door bracket 48 is installed in the middle of the door, and the door bracket 48 is provided with a door The walking track of the rocker arm 49; after the card-discharging door 5 is discharged, the push head closes the conveying outlet and at the same time one end is lowered to be flush with the exit end of the bottom rail 414, and the rotor rocker arm 415 pushes the mahjong tiles out one by one along the slope of the card-discharging door 5, and the rotor rocker arm 415 pushes the last pile onto the card-discharging door 5. There is a positioning magnetic control on the rotor main frame 45 below the rotor rocker arm 415. When the rotor rocker arm 415 corresponds to the magnetic control, the rotor rocker arm 415 stops. At this time, one end of the card-discharging door 5 is lifted and is flush with the table surface, and the rotor rocker arm 415 turns an angle and stops in a safe position between the track exit and the conveying outlet. The mahjong tiles on the table are in place and the players can start the game.

[0026] This device utilizes a motor-driven gear 42 that directly drives the rotor main gear sprocket 43. This structure maximizes the sprocket diameter within the maximum range of the rotational propulsion stroke, thus maximizing the motor-driven torque ratio. This structure utilizes a long, thick shaft (φ ≥ 10 mm) pre-molded in the center of the rotor main frame 45, ensuring a secure foundation and high shaft concentricity. This ensures balanced and stable operation of the rotor main gear sprocket 43 and rotor rocker arm 415. The rotor main gear sprocket 43 and rotor rocker arm 415 feature three slots to accommodate three different card push positions. The three contact surfaces of the rotor main frame 45 track—the inner ring 412, outer ring 413, and bottom rail 414—are all constructed of a lubricating plastic to ensure smooth, low-stress sliding of the bars within the track's arc. The outer diameter of the inner ring 412 increases as the track's card size decreases, while the outer diameter of the inner ring 412 decreases as the track's card size increases. Different card types have different inner ring 412 diameters. The card inlet end of the bottom rail 414 has a low outer slope and a high inner slope, facilitating smooth and stable card pushing from the card holder of the stacking machine head 3 into the track of the rotor main frame 45. The card outlet end of the bottom rail 414 has a low inner slope and a high outer slope, aligned with the card outlet door 5 when it is at its lowest point. The height of the slope varies depending on the thickness of the cards, facilitating smooth and stable card ejection from the outlet door 5. To ensure the flush upward slope of the card outlet end of the bottom rail 414 of the rotor main frame 45, the underside of the rotor main frame 45 below the card outlet door 5 is provided with two door retaining ribs 416, each of which adjusts to the thickness of the cards. To accommodate the varying widths of the cards during draw, the door width and the thickness of the door motor side bracket 410 are matched to the card width. A magnetic door mount 411, mounted on the inside of the door's side bracket, rotates in conjunction with the door motor, driving a door rocker arm 49 within the track of the door bracket 48. Clockwise rotation lowers one end of the door to open and release cards, while counterclockwise rotation raises one end to close and release cards. The door bracket 48 is secured to the door with two screws. Loosening the screws and adding or removing shims fine-tune the flatness of the door 5 and the panel. The in-track push-to-load mechanism simplifies assembly and disassembly, and the incline height of the bottom rail 414 at the release end can be adjusted to suit the thickness of the cards. This highly versatile device operates smoothly and reliably.

[0027] In one embodiment, the card-discharging door 5 includes a card-discharging door mounting seat 47, a door bracket 48 and a door rocker arm 49. The card-discharging door mounting seat 47 is rotatably mounted on the front end of the card-discharging door 5, the door bracket 48 is fixedly mounted in the middle of the card-discharging door 5, and the door rocker arm 49 is rotatably mounted on the door bracket 48. The card-discharging door 5 is provided with a door motor side bracket 410, and a door magnetic control seat 411 is installed on the door motor side bracket 410. The thickness of the door motor side bracket 410 matches the width of the card shape, and a door limiting rib 416 is provided on the bottom surface of the rotor main frame 45 below the card-discharging door 5.

[0028] As you can understand, the main rotor frame 45 connects to the card exit door 5 at the end of the track via a small shaft and the door mounting bracket 47. A door bracket 48 is mounted in the middle of the door, which features a running track for the door rocker arm 49. After the door 5 is ejected, the pusher closes the delivery port and simultaneously lowers one end to align with the exit end of the bottom rail 414. The rotor rocker arm 415 pushes the tiles out along the ramp of the door 5. The rotor main gear sprocket 43 and the rotor rocker arm 415 have three slots to accommodate three different card push positions. The three contact surfaces of the rotor frame 45 track—the inner ring 412, outer ring 413, and bottom rail 414—are all made of a plastic with inherent lubricity to ensure smooth, low-stress sliding of the tiles as they move in a circular arc within the track. The diameter of the inner ring 412 increases as the outer diameter increases, indicating a smaller track card size; the diameter of the inner ring 412 decreases as the outer diameter decreases, indicating a larger track card size. Different inner ring 412 diameters are used for different card types. The card inlet end of the bottom rail 414 has a low outer slope and a high inner slope, facilitating smooth and stable card pushing from the card holder of the stacking machine head 3 into the track of the rotor main frame 45. The card outlet end of the bottom rail 414 has a low inner slope and a high outer slope, aligned with the card outlet door 5 when it is at its lowest point. The height of the slope varies depending on the thickness of the cards, facilitating smooth and stable card ejection from the outlet door 5. To ensure the flush upward slope of the card outlet end of the bottom rail 414 of the rotor main frame 45, the underside of the rotor main frame 45 below the card outlet door 5 is provided with two door retaining ribs 416, each of which adjusts to the thickness of the cards. To accommodate the varying widths of the cards during draw, the door width and the thickness of the door motor side bracket 410 are matched to the card width. A magnetic door mount 411, mounted on the inside of the door's side bracket, rotates in conjunction with the door motor, driving a door rocker arm 49 within the track of the door bracket 48. Clockwise rotation lowers the door to open and release cards, while counterclockwise rotation raises and closes the door. Door bracket 48 is secured to the door with two screws. Loosening the screws and adding or removing shims allows for fine-tuning the flatness of the door 5 relative to the panel.

[0029] 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.
