Problems solved by technology

[0004] (1) At the beginning of the shuffling, since all the mahjong tiles fall into the upper surface of the shuffling board at once and cause accumulation, the relatively static scraping arm causes a very large resistance to the pile of mahjong tiles, resulting in the movement of the shuffling board The resistance is very large, and a large-torque motor is required to drive the shuffle plate, which increases the cost of the mahjong machine; at the same time, when the mahjong tiles pile up and cause congestion, the high-torque motor is easy to damage the linkage gear mechanism
[0005] (2) The resistance caused by the mahjong tile pile to the scraper arm is very large, resulting in the scraper arm being easily deformed, and the material performance requirements for the scraper arm are relatively high. As time goes by, the scraper arm becomes invalid due to excessive deformation, resulting in failure of the mahjong tiles. Arrived at the card exit, causing a failure
[0006] (3) Due to the blocking and guiding of the fixed scraper arm, the pile of mahjong tiles quickly slides upwards to the upper tile opening, forming a pile at the upper tile opening. Since each upper tile opening can only absorb one mahjong tile at a time, and the mahjong tiles are piled up on the upper tile opening As a result, the interaction force between the mahjong tiles is relatively large, and the magnetic attraction force of the card loading mechanism is not enough to allow the mahjong tiles to leave the pile.
[0007] (4) During the rotation of the shuffling board, the large resistance of the mahjong tiles causes the deformation of the free end of the scraper arm, and the deformed free end of the scraper arm passes through the tiles and recovers rapidly, producing a large noise; in addition, Since the scraping arm is fixed and the shuffling plate rotates, there will be impact noise between the mahjong tiles and the scraping arm

Embodiment 1

[0046] A kind of scraper rotatable mahjong machine of the present embodiment, as figure 1 , figure 2 Shown, comprise shuffling big plate 10, scraping card mechanism 20 and center lifting dice tray mechanism 30.

[0047] In this example, if figure 2 , image 3 As shown, the card shuffling tray 10 is equipped with a tray drive device for driving the rotation of the card shuffling tray 10. The tray drive device includes a tray drive motor 13, and a first drive gear 14 is installed on the output shaft of the tray drive motor. A second driving ring gear 11 meshing with the first driving gear 14 is arranged on the bottom of the brand large plate 10 .

[0048] It should be noted that, in this embodiment, there is only one large disk drive motor, which is only a preferred implementation manner of this embodiment, and only a plurality of large disk drive motors may be provided as required. In addition, the transmission mode between the large disk drive motor and the shuffling large...

Embodiment 2

[0087] A kind of scraper rotatable mahjong machine of the present embodiment, as Figure 12 , Figure 13 Shown, comprise shuffling big plate 10, scraper 21 and central lifting dice tray mechanism 30.

[0088] In this example, if Figure 12 , Figure 13 As shown, the card shuffling tray 10 is equipped with a tray drive device for driving the rotation of the card shuffling tray 10. The tray drive device includes a tray drive motor 13, and a first drive gear 14 is installed on the output shaft of the tray drive motor. A second driving ring gear 11 meshing with the first driving gear 14 is arranged on the bottom of the brand large plate 10 .

[0089] It should be noted that, in this embodiment, there is only one large disk drive motor, which is only a preferred implementation manner of this embodiment, and only a plurality of large disk drive motors may be provided as required. In addition, the transmission mode between the large disk drive motor and the shuffling large disk i...

Embodiment 3

[0114] A kind of card scratcher rotatable mahjong machine of this embodiment differs from embodiment two in that, as Figure 15 As shown, a fifth drive gear 27 is also included. The fifth driving gear 27 is arranged coaxially with the third driving gear 26 , and the fifth driving gear 27 meshes with the second driving ring gear 11 .

[0115] The special feature of this embodiment is that the fifth drive gear 27 is connected to the drive shaft through a one-way bearing. When both the card scraper and the card shuffling tray are rotating in the forward direction, the driving force of the card scraping drive motor is transmitted to the card shuffling tray through the fifth drive gear, which provides auxiliary power for the card shuffling tray, which helps in the initial stage of shuffling. When there are many mahjong tiles on the board, reduce the load on the shuffling drive motor.

[0116] When the card scraper rotates in the opposite direction relative to the shuffling board,...

Abstract

The invention relates to the technical field of mahjong machines, and particularly discloses a mahjong machine with a rotatable tile scraper, which at least comprises a large shuffling plate, a tile scraper and a control system, and is characterized in that the large shuffling plate is provided with a large plate driving device for driving the large shuffling plate to rotate; the tile scraper andthe large shuffling plate are coaxially arranged, the tile scraper is configured to be rotatably and movably connected with the large shuffling plate, and the tile scraper is provided with a tile scraping driving device used for driving the tile scraper to independently rotate relative to the large shuffling plate; and the control system controls the large shuffling plate and the tile scraper to rotate independently. In the structure, the rotation of the tile scraper and the rotation of the large shuffling plate are independently designed, the rotation direction, the rotation speed, the rotation angle and the like of the tile scraper cannot be affected by the rotation of the large shuffling plate, and the control mode is more flexible.

Description

technical field [0001] The invention relates to the technical field of mahjong machines, in particular to a mahjong machine with a rotatable scraper. Background technique [0002] In the mahjong machine in the prior art, the scraping mechanism is usually fixed, and the shuffling plate rotates when shuffling the cards. The scraping arm of the scraping mechanism plays a role in blocking and guiding the mahjong tiles on the shuffling plate, thereby promoting The mahjong tiles on the shuffle board move upwards. [0003] The defects caused by the fixed scraping mechanism in the prior art are: [0004] (1) At the beginning of the shuffling, since all the mahjong tiles fall into the upper surface of the shuffling board at once and cause accumulation, the relatively static scraping arm causes a very large resistance to the pile of mahjong tiles, resulting in the movement of the shuffling board The resistance is very large, and a high-torque motor is required to drive the shuffling...
