Description

Technical Field

[0001] The invention relates to the field of mahjong machines, and more particularly to a modularized, fast-changing conveyor belt tabletop card-pushing mahjong machine and a control method thereof. Background Art

[0002] With the continuous improvement of living standards, people's leisure and entertainment life is becoming more and more abundant, and mahjong is one of the leisure and entertainment activities that people are happy to participate in.

[0003] Usually, players play mahjong with a set of mahjong tiles. After a round, players shuffle the tiles and arrange the tiles before continuing to the next round. Among them, the convenient and labor-saving mahjong machine is loved by many people. The mahjong machine saves players the time of shuffling and arranging the tiles by themselves, and improves the entertainment experience of players.

[0004] At present, China Patent Network discloses a card pulling mechanism and mahjong machine, publication number CN207041894U, which relates to the technical field of indoor game equipment to alleviate the technical problem that the mahjong tiles are easily stuck in the mahjong tile path during the process of pulling the mahjong tiles by the existing card pulling mechanism, resulting in the inability to smoothly pull out the mahjong tiles. The card pulling mechanism provided by the present invention includes a tile path, a card pulling device that reciprocates along the tile path; the card pulling device is used to push the mahjong tiles to move along the tile path; the tile path is arc-shaped.

[0005] Although the card pulling mechanism and mahjong machine in the above patent have the advantage of simple structure, the mahjong machine requires not only a card pulling path but also multiple transmission motors, which results in a larger size and weight of the mahjong machine, and thus a higher production cost. Summary of the invention

[0006] In order to overcome the problem of large size and high production cost of traditional mahjong machines in the prior art, the present invention provides a modular quick-change conveyor belt tabletop card-pushing mahjong machine and a control method thereof which have the advantages of small size and low production cost.

[0007] The present invention discloses a modularized quick-change conveyor belt tabletop card-pushing mahjong machine and a control method thereof, comprising a square base, a tabletop being arranged above the square base, at least four supporting members being arranged between the tabletop and the square base, supporting feet being arranged at the four corners of the square base respectively, a card-shuffling mechanism being arranged on the square base, a card-discharging end of the card-shuffling mechanism being provided with a card-sucking mechanism, and a card-lifting and card-pushing assembly being arranged at the card-discharging end of the card-sucking mechanism.

[0008] After shuffling the cards, a traditional mahjong machine first pulls the sorted mahjong tiles into a card storage slot through a card pulling mechanism, and then raises the mahjong tiles to the tabletop through a card raising mechanism. Since it requires mechanisms such as a card pulling slide inside, the traditional mahjong machine requires a large internal volume and is difficult to carry.

[0009] When the present invention is in operation, the shuffled mahjong tiles are directly pushed into the card lifting and pushing assembly without using a card pulling slide. By lifting and pushing the tiles, the arranged mahjong tiles are first lifted to the tabletop, and then pushed into the tabletop. This method allows the mahjong machine to be free of the need to provide a card pushing slide, saving internal space, thereby reducing the size of the mahjong machine, making it light and flexible, and easy to carry.

[0010] Preferably, the shuffling mechanism comprises a large plate installed at the upper end of a square base, a large plate motor is provided below the large plate to provide power for the large plate, a card-moving bar for moving mahjong tiles is provided in the center of the large plate, a card-sucking mechanism is provided on the periphery of the card-moving bar, and a card-turning magnet for turning over the mahjong tiles is provided between the card-moving bar and the card-sucking mechanism.

[0011] Preferably, the card suction mechanism includes 4 evenly distributed shuffling bucket assemblies, the shuffling bucket assembly includes a main plate fixed on a square base, a mahjong card conveying groove is opened on the front of the main plate, a conveyor belt is installed in the mahjong card conveying groove, a conveyor belt direction groove for guiding the conveyor belt is provided below the mahjong card conveying groove, a card suction wheel is provided on the left side of the mahjong card conveying groove, a driving wheel is provided below the mahjong card conveying groove, the card suction wheel and the driving wheel are connected through a conveyor belt transmission, a power motor is provided on the back of the main plate, the driving wheel is installed on the output shaft of the power motor, a tensioning wheel for adjusting the tension of the conveyor belt is provided outside the output shaft, a tensioning bracket is provided on the conveyor belt direction groove, the tensioning bracket is connected to the tensioning wheel through a spring, an adjusting wheel used in conjunction with the tensioning wheel is provided on the left side of the tensioning wheel, a side panel is installed outside the conveyor belt, a connecting groove is opened at the right end of the main plate, and a slot protrusion matching the connecting groove is provided on the side panel.

[0012] The tension wheel is installed on the power motor. The tension wheel takes the output shaft of the power motor as a fulcrum and is connected to the tension wheel bracket through a spring. The tension of the conveyor belt can be freely adjusted. Compared with the traditional mahjong machine, this structure shortens the travel distance of the conveyor belt, saves part of the installation space of the conveyor belt, and thus reduces the production cost.

[0013] The side panel is movably connected to the main board through the connecting groove and the slot convex block. When installing, the side panel is connected to the main board from top to bottom. This structure is a modular component, which is convenient for the assembly of the manipulator and saves labor costs. This structure also solves the problem that the entire shuffling barrel plastic part must be removed when replacing the conveyor belt of the mahjong machine in the past. When replacing the conveyor belt, you only need to pull out the side panel to replace and install the conveyor belt.

[0014] Preferably, the card-raising and card-pushing assembly includes a card storage slot, a card-raising mechanism is provided at the lower end of the card storage slot, a card-pushing mechanism is provided at the back of the card-raising mechanism, a card-feeding mechanism is provided on the left side of the card storage slot, two card-pushing installation positions for installing the card-pushing mechanism are opened at the bottom of the card storage slot, and a limit strip for fixing the position of mahjong cards is provided in the card storage slot.

[0015] Preferably, the card-raising mechanism comprises a card-raising bracket installed at the lower end of the card storage slot, a gear mounting frame is provided on the card-raising bracket, rocker gears are respectively provided at the left and right ends of the front face of the gear mounting frame, a card-raising rocker arm is provided on the front face of the rocker gear, two card-raising transmission wheels in gearing engagement are provided between the two rocker gears, the rocker gears are gearingly engaged with the card-raising transmission wheels, a two-way motor is provided on the left side of the gear mounting frame, a left one-way wheel and a right one-way wheel are respectively provided on the output shaft of the two-way motor, a transition wheel is gearingly engaged on the right one-way wheel, the transition wheel is gearingly engaged with the rocker gear located at the left end of the gear mounting frame, and the left one-way wheel is gearingly connected with the card-feeding mechanism.

[0016] When raising the cards, the two-way motor will rotate counterclockwise. At this time, the two-way motor drives the right one-way wheel to rotate, and the left one-way wheel remains stationary. The right one-way wheel drives the rocker gear to rotate through the transition wheel. During the rocker gear process, the card raising rocker arm on the rocker gear will raise the card storage slot, thereby lifting the mahjong tiles to the table top.

[0017] The card storage slot can be made of aluminum metal material or PP plastic material, which can reduce the weight of the card storage slot and thus reduce the total weight of the mahjong machine.

[0018] Preferably, the card pushing mechanism comprises a card pushing slider installed on a card pushing mounting position, a card pushing rocker arm is arranged inside the card pushing slider, a transmission rod perpendicular to the card pushing rocker arm is arranged at the bottom of one end of the card pushing rocker arm, a bevel gear is arranged on the transmission rod, card pushing transmission wheels are respectively arranged at the left and right ends of the back side of the gear mounting frame, the card lifting transmission wheel and the card pushing transmission wheel are coaxially transmitted, the bevel gear is gear-engaged with the card pushing transmission wheel, a card pushing plate is arranged in the card storage slot, a push rod mounting position is opened on the back of the card storage slot, a card pushing rod is arranged on the back of the card pushing plate, a sliding block is arranged at the bottom of the card pushing rod, the sliding block is installed in the card pushing slider, and a sliding groove matching the card pushing rocker arm is arranged at the tail end of the sliding block.

[0019] The transmission rod is a connecting shaft between the bevel gear and the card pushing rocker arm, and when the card lifting rocker arm lifts the card storage slot, the transmission rod will also lift simultaneously. The card pushing rocker arm is a semicircular shaft or a cam shaft.

[0020] When the card storage slot rises to the table top, the card lifting rocker arm is at the highest point, and then the two-way motor will continue to rotate counterclockwise. At this time, the card lifting rocker arm rotates, causing the card storage slot to begin to descend. At the moment the card storage slot descends, since the rocker arm gear and the card pushing transmission wheel are coaxially transmitted, the rocker arm gear drives the card pushing transmission wheel to rotate, and the card pushing transmission wheel then drives the bevel gear to rotate, and the bevel gear drives the card pushing rocker arm to rotate, and the card pushing rocker arm pushes out the sliding block, and the sliding block drives the card pushing rod and the card pushing board to move, and the card pushing board finally pushes the mahjong cards in the card storage slot onto the table top. This process lasts less than 1 second, that is, when the card storage slot has not completely left the table top, the card pushing board pushes the mahjong cards into the table top, and then the two-way motor continues to rotate counterclockwise until the card storage slot and the card pushing board are reset.

[0021] Preferably, the card-advancing mechanism comprises a card-sinking seat, a card-sinking wheel is provided on the right side of the card-sinking seat, a card-sinking rod is fixed to the front of the card-sinking wheel, a card-advancing rod is fixed to the back of the card-sinking wheel, one end of the card-sinking rod is fixedly connected to the bottom of the card-sinking seat, a card-sinking transmission wheel is toothedly engaged on the card-sinking wheel, the card-sinking transmission wheel is toothedly engaged with the left one-way wheel, a pushing head is provided on the left side of the card-sinking seat, the lower end of the pushing head is fixedly connected to the card-advancing rod, and a card-blocking seat is provided at the rear end of the card-sinking seat.

[0022] Preferably, the pusher head and the card sinking seat are connected via a pusher head connecting rod, a card block seat bracket is provided at the bottom of the card block seat, and a light controller is provided on the card block seat.

[0023] After the shuffling barrel has shuffled the cards, the mahjong tiles with the characters facing down are sent to the sinking seat through the conveyor belt. At this time, when the light controller senses the mahjong tiles, the two-way motor rotates clockwise. At this time, the left one-way wheel rotates to drive the sinking transmission wheel, and the sinking transmission wheel drives the sinking wheel to rotate. The sinking wheel lowers the sinking seat through the sinking rod, stacks two mahjong tiles into a pile and lifts it up, then the two-way motor rotates, the sinking wheel drives the card feed rod, and the card feed rod drives the push head to push the stacked mahjong pile into the card storage slot, and repeats the above steps until the card storage slot is full of mahjong tiles.

[0024] The card lifting mechanism, card pushing mechanism and card feeding mechanism of the present invention are all driven by a unified bidirectional motor. Compared with the traditional mahjong machine, the number of motors is significantly reduced, thereby reducing the overall weight of the mahjong machine and reducing the noise caused by the motor when in use.

[0025] The traditional mahjong machine has a motor in each of the card lifting mechanism, card pushing mechanism and card feeding mechanism, which consumes a lot of energy when in use, and makes the traditional mahjong machine large in size and heavy in weight. The noise is also large when multiple motors are running. The present invention allows the card lifting mechanism, card pushing mechanism and card feeding mechanism to share a bidirectional motor, and cleverly completes their respective power functions through left and right one-way gears. The present invention has the advantages of energy saving, material saving and low labor cost, improves the energy saving and emission reduction effect, and meets the needs of a larger population.

[0026] The control method of the present invention:

[0027] 1. When shuffling the cards, first scatter the mahjong tiles onto the large plate of the shuffling mechanism.

[0028] 2. When shuffling begins, the disc motor in the shuffling mechanism will drive the disc to rotate in a clockwise direction. During the rotation of the disc, the card-moving bar on the disc will move the mahjong tiles to the edge of the disc.

[0029] 3. During the card-moving process, the flipping magnets on the edge of the plate will flip all the mahjong tiles so that the written side faces up.

[0030] 4. When a mahjong tile with the face down approaches the card suction mechanism, the card suction wheel on the card suction mechanism will attract the mahjong tile, and then the mahjong tile will be sent to the card feeding mechanism through the conveyor belt on the card suction mechanism.

[0031] 5. When the mahjong tiles reach the card feeding mechanism, the bidirectional motor will rotate clockwise to drive the card sinking wheel. The card sinking wheel will drive the card sinking seat during the rotation. The card sinking seat will stack two mahjong tiles into a pile and lift them up. Then, the stacked mahjong tiles will be sent into the card storage slot through the card feeding rod and the push head.

[0032] 6. When the number of mahjong tiles in the card storage slot reaches the required number, the bidirectional motor stops rotating to prevent excess mahjong tiles from entering the card storage slot.

[0033] 7. When the mahjong tiles need to be raised, the bidirectional motor will rotate counterclockwise to drive the lifting mechanism, and the lifting rocker arm in the lifting mechanism will lift the card storage slot.

[0034] 8. When the card-lifting rocker arm reaches the highest point, the bottom of the mahjong tiles in the card slot is parallel to the table top. At this time, the bidirectional motor will continue to rotate counterclockwise to drive the card-pushing mechanism. The bevel gear in the card-pushing mechanism drives the transmission rod to rotate, and the transmission rod drives the card-pushing rocker arm to push the card-pushing rod, which pushes the mahjong tiles in the card slot to the table top.

[0035] The present invention has the following beneficial effects:

[0036] 1. It allows customers to play larger mahjong tiles on a smaller table.

[0037] 2. Modular design makes it easy for manufacturers to assemble and maintain.

[0038] 3. There are fewer motors inside the mahjong machine, and less noise when working.

[0039] 4. The production cost is low and the working stability is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] The control method of the present invention is:

[0062] 1. When shuffling the cards, first scatter the mahjong tiles onto the large plate of the shuffling mechanism.

[0063] 2. When shuffling begins, the disc motor in the shuffling mechanism will drive the disc to rotate in a clockwise direction. During the rotation of the disc, the card-moving bar on the disc will move the mahjong tiles to the edge of the disc.

[0064] 3. During the card-moving process, the flipping magnets on the edge of the plate will flip all the mahjong tiles so that the written side faces up.

[0065] 4. When a Mahjong tile with the face down approaches the card suction mechanism, the card suction wheel 6 on the card suction mechanism will attract the Mahjong tile, and then the Mahjong tile will be sent to the card feeding mechanism through the conveyor belt 5 on the card suction mechanism.

[0066] 5. When the mahjong tiles reach the card feeding mechanism, the bidirectional motor 20 will rotate clockwise to drive the card sinking wheel 35. The card sinking wheel 35 will drive the card sinking seat 34 during the rotation process. The card sinking seat 34 will stack two mahjong tiles into a pile and lift them up. Then, the stacked mahjong tiles will be sent into the card storage slot 12 through the card feeding rod 37 and the pushing head 39.

[0067] 6. When the number of mahjong tiles in the card storage slot 12 reaches the required number, the bidirectional motor 20 stops rotating, thereby preventing excess mahjong tiles from entering the card storage slot 12.

[0068] 7. When the mahjong tiles need to be raised, the bidirectional motor 20 will rotate counterclockwise to drive the lifting mechanism. When the lifting rocker arm 18 rotates from point A to point B, the arc between point A and point B is 120 degrees, and the lifting rocker arm 18 lifts the mahjong slot 12 to the table top 47.

[0069] 8. In the process of the card raising rocker arm 18 rotating from point A to point B, the card pushing rocker arm 25 rotates from point a to point b. The arc between point a and point b is 120 degrees. The card pushing rocker arm 25 has not entered the slide groove 33 at this time, so the card pushing rocker arm 25 does not push the sliding block 32, and the card storage slot 12 does not move horizontally at this time.

[0070] 9. When the card raising rocker arm 18 reaches the highest point, the bottom of the mahjong cards in the card storage slot 12 is exactly parallel to the desktop 47, and the bidirectional motor 20 will continue to rotate counterclockwise to drive the card pushing mechanism. At this time, the card raising rocker arm 18 rotates from point B to point C, and the arc between point B and point C is 120 degrees. At this time, the card storage slot 12 has not left the desktop 47.

[0071] During the process of the card-lifting rocker arm 18 rotating from point B to point C, the card-pushing mechanism is started, and the bevel gear 27 in the card-pushing mechanism drives the transmission rod 26 to rotate, and the transmission rod 26 drives the card-pushing rocker arm 25 to push the card-pushing plate 29. When pushing the cards, the card-pushing rocker arm 25 rotates from point b to point c. At this time, the card-pushing rocker arm 25 pushes the sliding block 32, and the sliding block 32 drives the card-pushing plate 29 to instantly push the mahjong cards away from the card storage slot 12 to the table top 47.

[0072] After the mahjong tiles are pushed out of the card storage slot 12, the bidirectional motor 20 will continue to rotate counterclockwise, and the card raising rocker arm 18 will rotate from point C to point A. The arc between point C and point A is 120 degrees, and the card storage slot 12 leaves the desktop to the initial position. During the process of the card raising rocker arm 18 rotating from point C to point A, the card pushing rocker arm 25 will rotate from point c to point a, and the card pushing rocker arm 25 will drive the sliding block 32 to reset, and the sliding block 32 will then drive the card pushing plate 29 to reset.

[0073] The above description is only a specific embodiment of the present invention, but the structural features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.

A control method for a modular quick-change conveyor belt tabletop mahjong machine according to claim 1, characterized in that: The control method is: When shuffling the cards, first scatter the mahjong tiles onto the large plate (42) of the shuffling mechanism; When shuffling begins, the motor of the large plate (42) in the shuffling mechanism drives the large plate (42) to rotate in a clockwise direction. During the rotation of the large plate (42), the card-moving strips on the large plate (42) move the mahjong tiles toward the edge of the large plate (42); During the card-moving process of the card-moving bar, the flipping magnets on the edge of the large plate (42) will flip all the mahjong tiles so that the words on them face upwards; When a mahjong tile with the face down approaches the card suction mechanism, the card suction wheel (6) on the card suction mechanism will attract the mahjong tile, and then the conveyor belt (5) on the card suction mechanism will send the mahjong tile to the card feeding mechanism; When the mahjong tiles arrive at the card feeding mechanism, the bidirectional motor (20) rotates clockwise to drive the card sinking wheel (35), and the card sinking wheel (35) drives the card sinking seat (34) during the rotation process. The card sinking seat (34) stacks two mahjong tiles into a pile and lifts them up. Then, the stacked mahjong tiles are sent into the card storage slot (12) through the card feeding rod (37) and the pushing head (39); When the required number of mahjong tiles in the card storage slot (12) is reached, the bidirectional motor (20) stops rotating, thereby preventing excess mahjong tiles from entering the card storage slot (12); When the mahjong tiles need to be raised, the bidirectional motor (20) will rotate counterclockwise to drive the tile raising mechanism, and the tile raising rocker arm (18) in the tile raising mechanism will raise the tile storage slot (12); When the card-lifting rocker arm (18) reaches the highest point, the bottom of the mahjong tiles in the card storage slot (12) is exactly parallel to the tabletop. At this time, the bidirectional motor (20) will continue to rotate counterclockwise to drive the card-pushing mechanism. The bevel gear (27) in the card-pushing mechanism drives the transmission rod (26) to rotate. The transmission rod (26) then drives the card-pushing rocker arm (25) to push the card-pushing rod (31). The card-pushing rod (31) pushes the mahjong tiles in the card storage slot (12) onto the tabletop.
