Technical Field

[0001] The utility model relates to the field of entertainment equipment, in particular to a card feeding mechanism of a mahjong machine. Background Art

[0002] As people's living standards improve, there are more and more entertainment projects in life. Mahjong has been widely spread for its entertainment and good brain training effect. At the same time, with the development of technology, the use of automatic mahjong machines has become more and more widespread. The traditional household automatic mahjong machine structure requires the user to operate the control button of the fully automatic mahjong table, raise the operating panel, expose the card entry on the table, and the user pushes the magnetic mahjong tiles on the table into the table, and then retracts the operating panel. After that, the pre-laid mahjong tiles in the mahjong table are all pushed to the table through the lifting mechanism, and people can continue to play, and so on.

[0003] When people go out, they will play mahjong for entertainment when they get together. However, home mahjong machines are large and inconvenient to carry, so small portable mahjong machines have emerged.

[0004] The card-feeding mechanism of the portable mahjong machine in the prior art is similar to the driving structure of the traditional non-portable mahjong machine. The large stroke required to achieve the card-feeding effect requires a large internal space, so it needs to be further improved to reduce the size and facilitate use. Utility Model Content

[0005] The utility model aims at the deficiencies in the prior art and provides a card-feeding mechanism for a mahjong machine, comprising a card-feeding cover plate, a fixing frame and a cover plate driving unit. The card-feeding cover plate is arranged in a shape corresponding to a card-feeding opening on a table top, the close part of the card-feeding cover plate serves as a rotating end, and the far end serves as a movable end. The card-feeding cover plate is rotatably connected to the upper part of the fixing frame through the rotating ends, and the cover plate driving unit controls the card-feeding cover plate to rotate and droop, thereby opening the inner cavity entrance of the mahjong machine.

[0006] Preferably, the cover driving unit includes a guide protrusion, a rotating shaft, a rotating support rod and a card-feeding motor. The guide protrusion is arranged in a trapezoidal shape at the bottom of the cover, one side of the guide protrusion is inclined, the guide protrusion is abutted against the rotating shaft up and down, the rotating shaft is connected to the rotating support rod, and the card-feeding motor drives the rotating support rod.

[0007] Preferably, a support rod and a hinge are provided outside the fixing frame, and the card entry cover is hinged to the support rod through the hinge.

[0008] Compared with the prior art, the beneficial effect of the utility model is that by providing a controllable card-feeding cover plate, the stroke of the card-feeding mechanism when feeding cards is reduced, thereby eliminating the bulky lifting card-feeding mechanism, and the internal mechanism is streamlined and occupies less space, thereby reducing the overall volume of the mahjong machine.

The card-entering cover plate 2 is arranged to correspond to the shape of the card-entering port 12. The card-entering cover plate 2 is divided into two symmetrical pieces. The close parts of the two card-entering cover plates 2 serve as rotating ends, and the ends away serve as movable ends. The card-entering cover plates 2 are rotatably connected to the upper part of the fixed frame 21 through the rotating ends. Specifically, a support rod 23 is arranged outside the fixed frame 21. The support rod 23 is L-shaped. Two groups of the support rods 23 are symmetrically arranged on both sides of the fixed frame 21 in a lifting shape. A hinge 22 is arranged at the top of the support rod 23. One end of the hinge 22 is fixedly arranged at the top of the support rod 23, and the other end is fixedly arranged at the rotating end of the card-entering cover plate 2, so that the card-entering cover plate 2 is hinged to the support rod 23 for rotation.

[0025] The cover driving unit is used to control the rotation angle of the card entry cover 2, that is, the opening size of the card entry port 12. The cover driving unit includes a guide protrusion 26, a rotating shaft 25, a rotating support rod 24 and a card entry motor 3. The guide protrusion 26 is arranged in a trapezoidal shape, and one side of the guide protrusion 26 is arranged obliquely and abuts against the rotating shaft 25 up and down. The rotating shaft 25 can be arranged in the form of a rotating rod or a rotating bearing. This structure is a prior art and will not be repeated here. The rotating shaft 25 is connected to the rotating support rod 24, and the rotating support rod 24 is driven by the card entry motor 3. The axis of the card entry motor 3 is provided with a linkage block 32, and the linkage block 32 is connected to the two rotating support rods 24. The side of the fixed frame 21 is provided with a movable groove, and the rotating support rod 24 is sleeved in the movable groove and moves horizontally.

A control console is disposed on the top of the fixing frame 21 for interacting with the operator.

[0026] The shuffling mechanism includes a shuffling plate 8 and a shuffling motor 9. The bottom of the shuffling plate 8 is provided with a guide wheel, the upper part of the shuffling plate 8 is provided with a shuffling protrusion, the peripheral side of the shuffling plate 8 is provided with meshing teeth, the shuffling motor 9 is arranged on the side of the shuffling plate 8, and the shuffling motor 9 is meshed with the peripheral gear of the shuffling plate 8 through a driving gear. An arc-shaped baffle plate is arranged above the peripheral side of the shuffling plate 8 to block and guide mahjong cards. The shuffling plate 8 guides the mahjong cards to rotate below the card suction mechanism through the notch provided on the baffle plate.

[0027] The card suction mechanism is as follows Fig.10, including a card suction wheel 72, a conveyor belt 7 and a conveyor belt driving device. The conveyor belt 7 is a flexible rubber conveyor belt. The card suction wheel 72 is provided with a magnetic body, which is adsorbed by the magnets provided in the mahjong tiles so that the mahjong tiles are transferred from the shuffling plate 8 to the conveyor belt 7. The conveyor belt driving device includes a driving wheel 73, a transmission wheel 74 and a pulley driving motor 71. The driving wheel 73 is coaxially arranged with the pulley driving motor 71, and the transmission wheel 74 is sleeved in the conveyor belt 7. Fig.11 The transmission wheel 74 is a drum-shaped transmission wheel, the middle part of which is drum-shaped, and the two ends gradually narrow outward. When the conveyor belt 7 rotates, if the conveyor belt 7 is deviated from the middle section of the drum-shaped transmission wheel by external force, the surface of the conveyor belt 7 on the side farther from the center of the drum-shaped transmission wheel shrinks, and the tension decreases, while the tension of the conveyor belt 7 near the middle section is relatively large. When the area with large tension fits with the surface of the drum-shaped transmission wheel, the relative pressure is greater, resulting in greater friction, so that the conveyor belt 7 moves to the side with greater friction, so that the conveyor belt 7 that has deviated before returns to the right position. Other settings and uses of the card suction mechanism are prior art and will not be repeated here.

[0028] The card sucking mechanism is provided with a pushing mechanism at the rear part thereof, which is used to push the mahjong tiles so that the mahjong tiles are arranged in a row. The pushing mechanism comprises a pushing motor 61, a pushing cam 62, a pushing guide rod 63 and a pushing piece 6. According to the received sensor signal, the pushing motor 61 drives the pushing cam 62 to rotate. The rear part of the pushing piece 6 is movably sleeved on the pushing guide rod 63, and the pushing cam 62 drives the pushing piece 6 to reciprocate, so as to push the stack of mahjong tiles to one side for arrangement.

[0029] The card pushing device comprises a card pushing plate 5, a card pushing motor 51, a card pushing cam 53, a card pushing guide rod 54 and a motion guide rod 55. The card pushing cam 53 is arranged on the output shaft of the card pushing motor 51, and a push plate guide rod is arranged on the card pushing cam 53. The card pushing guide rod 54 is arranged in an arc shape, and a lever is arranged between two groups of the card pushing guide rods 54. The card pushing cam 53 is movably abutted against the lever. The card pushing cam 53 rotates to abut against the lever so that the card pushing guide rod 54 moves, and the card pushing plate 5 is rotated and pushed out. The motion guide rods 55 are evenly arranged on both sides of the rear of the card pushing guide rod 54, and the motion guide rods 55 are used to stabilize the stable movement of the card pushing plate 5.

[0030] The lifting mechanism includes a lifting platform 4, a guide unit of the lifting platform 4 and a driving unit of the lifting platform 4. The guide unit of the lifting platform 4 includes a guide rail 41, a linear bearing 42, a guide plate 43 and a lifting cam 44. The guide rail 41 is vertically arranged on the support plate 13, the linear bearing 42 is movably sleeved on the guide rail 41, and the outer wall of the linear bearing 42 is fixedly connected to one side of the lifting platform 4. The top of the guide plate 43 is fixedly arranged with the lifting platform 4, and the lower part of the guide plate 43 is provided with a guide slot hole, and the guide slot hole is concave in the middle and higher than the middle on both sides. The front end of the lifting cam 44 is movably sleeved in the guide slot hole to drive the guide plate 43 to move up and down.

[0031] The driving unit of the lifting platform 4 includes a driving gear shaft 52 and a lifting gear shaft 45. The driving gear shafts 52 symmetrically arranged in two groups are coaxially rotated with the card pushing motor 51. The driving gear shaft 52 and the lifting gear shaft 45 are mutually meshing bevel gears. The two groups of driving gear shafts 52 are coaxially arranged on both sides of the card pushing cam 53. The shaft of the lifting cam 44 is coaxially arranged with the output end of the lifting gear shaft 45.

[0032] The controller controls the operation of the sensor and the motor.

[0033] The energy storage mechanism includes a power module and a rechargeable battery. The power module charges the battery or directly supplies power to the electrical device. The rechargeable battery is arranged in the housing 1 and is electrically connected to each electrical device.

[0034] Usage process: The operator operates the control console to make the card-feeding motor 3 drive the rotating support rod 24 to rotate, and the rotating support rod 24 drives the rotating shaft 25 to abut against the guiding protrusion 26 and move toward the card-feeding cover plate 2. The card-feeding cover plate 2 rotates and droops under the action of gravity to expose the inner cavity of the housing 1. After pushing the mahjong tiles into the card-feeding port 12, the operator operates the control console to make the card-feeding motor 3 move in the opposite direction, so that the rotating shaft 25 moves away from the card-feeding cover plate 2 along the guiding protrusion 26, and pushes the card-feeding cover plate 2 to rise and buckle with the card-feeding port 12.

[0035] The mahjong tiles entering from the card inlet 12 fall on the shuffle tray 8, which rotates and shuffles the positions of the mahjong tiles. During the rotation, the mahjong tiles are gradually pushed to the entrance of the card suction mechanism. The mahjong tiles absorbed by the card suction mechanism are transferred to the rear frame along the conveyor belt 7. After the sensor counts the mahjong tiles, the two mahjong tiles stacked up and down are pushed to one side by the push motor 61 to drive the push sheet 6 to make room for the next group of mahjong tiles.

[0036] When the number of mahjong tiles counted by the sensor reaches the set number, the lifting platform 4 is in the low position. The pushing motor 51 drives the pushing cam 53 to drive the pushing guide rod 54 to move, and then the pushing plate 5 moves the mahjong tiles to the lifting platform 4. After the pushing plate 5 leaves the lifting platform 4 during the recovery process, the lifting cam 44 drives the lifting platform 4 to rise, and the four groups of mahjong tiles that have been arranged are raised to the height of the panel 11.
