Referring to fig. 1-9, an embodiment of the present utility model provides a mahjong table, using the following shuffling device of the mahjong table.

A shuffling device of a mahjong table comprises a shuffling large tray 1 and a shuffling tray 2 arranged outside the shuffling large tray 1; the shuffling tray 2 comprises a containing cavity 21 and a shuffling area 22 arranged above the containing cavity 21, the shuffling tray 1 can be lifted up and down in the containing cavity 21, and mahjong slowly enters the shuffling area 22 from the shuffling tray 1 in the lifting process of the shuffling tray 1; the shuffling large tray 1 is controlled to lift by a lifting device 3. Through holding more mahjong after the big dish 1 descends of shuffling, the diameter of inhaling the tablet dish 2 also diminishes, and corresponding rising tablet mouth is closer to the desktop center, can realize the effect of exempting from to push the tablet.

In an alternative embodiment, a convex ring 221 extending upwards is arranged at the periphery of the card sucking area 22, and a stop block 222 is uniformly arranged on the surface of the card sucking area 22. The mahjong can be blocked by the convex ring 221, so that the mahjong is prevented from being in excessive contact with the outer side. The stop 222 separates the mahjong pieces for convenient tile sucking.

In an alternative embodiment, a limit bar 211 is arranged in the accommodating cavity 21, and a notch matched with the limit bar 211 is arranged on the shuffling tray 1; an inner toothed disc 212 is provided at the bottom of the receiving chamber 21. Specifically, the internal gear plate 212 cooperates with a gear driven by a motor, so as to drive the card absorbing plate 2 to rotate. The limit strips 211 clamp the shuffling large tray 1 through the gaps, so that the shuffling large tray can be driven to rotate and can not be overturned in the up-and-down lifting process. The number of the limit bars 211 is preferably 4 if it is more stable.

In an alternative embodiment, the lifting device 3 comprises a base 31, a guide bar 32 provided on the base 31, and a lifting slider 33 moving along the guide bar 32; the base 31 is arranged on the outer side of the accommodating cavity 21, and a bearing is arranged between the base 31 and the bottom cavity of the accommodating cavity 21 to prevent friction and enable the accommodating cavity 21 to rotate more stably. The base 31 is stepped, the bottom area is larger, and the stability is better. Specifically, the lifting slider 33 may be a bearing, and the friction between the steel ball inside and the guide bead 32 is smaller. The base 31 is an integrally formed plastic member, and the guide rod 32 is a steel pipe.

In an alternative embodiment, a connecting rod 331 is disposed on the lifting slider 33, and the connecting rod 331 is driven to lift by a driving mechanism 4; a slider 332 is provided on the connection rod 331. Specifically, the connecting rod 331 is fan-shaped, so that strength can be increased, diameter can be reduced, and interference can be prevented.

Referring to fig. 6 and 7, the driving shaft 41 is divided into two halves. In an alternative embodiment, the driving mechanism 4 includes a driving shaft 41, and a lifting slot 42 disposed on the driving shaft 41; the lifting grooves 42 are annularly distributed along the outer surface of the driving rotating shaft 41; the lifting groove 42 gradually extends from a lowest position to a highest position along the circumferential direction and the axial direction, and then gradually extends from the highest position to the lowest position along the circumferential direction and the axial direction; the slider 332 is lifted up and down along the lifting groove 42. The slider 332 may be a bearing that is in rolling friction with the lifting groove 42 with less wear.

Referring to fig. 6 and 7, in an alternative embodiment, a worm wheel 43 is connected to the bottom of the driving shaft 41, and a worm 44 is connected to the worm wheel 43, and the worm 44 is driven by a motor. The worm gear has a self-locking function, and the motor is prevented from being burnt out due to the fact that the worm gear is heavier in the card lifting process and stays in the middle process.

Referring to fig. 1, in an alternative embodiment, the big shuffling tray 1 is a frustum with a large bottom and a small top, the shuffling claw 5 is attached to the upper surface of the big shuffling tray 1, and the shuffling claw 5 and the big shuffling tray 1 are lifted together with the lifting device 3. The shuffling claws 5 are the same as the shuffling large tray 1 and the common mahjong machine and are in a frustum shape. The bottom of the shuffling claw 5 is also fit with the surface of the shuffling tray 1.

Referring to fig. 8 and 9, in an alternative embodiment, the lifting device 3 is provided with a plurality of limit protrusions 34 distributed in the circumferential direction, and the shuffling claws 5 are provided with clamping grooves 51 matched with the limit protrusions 34. The cross section of the limiting protrusions 34 is triangular, the number of the limiting protrusions 34 is preferably 4, and the limiting protrusions 34 are annular in two-by-two mode. The cross section of the clamping groove 51 is triangular and is matched with the limiting protrusions 34 one by one. Because the positions of the shuffling claws 5 are changed in the rotating process, the structure is used to ensure that the shuffling claws are not manually adjusted, and the clamping can be automatically adjusted. A bearing is connected to the shuffling large tray 1, and the bearing is sleeved on the lifting slide 33. The shuffling claws 5 are also sleeved on the lifting slide block 33.

The specific working process comprises the following steps:

after the user finishes a set of mahjong, the mahjong is pushed into the shuffling device. At this point the dish washer 1 is at its lowest. The slider 332 is at the lowest of the elevation groove 42. The motor of the sucker plate 2 rotates to drive the inner tooth plate 212 at the bottom of the accommodating cavity 21 to rotate. The sucker cards 2 rotate to drive the big shuffling tray 1 to rotate together, and at the moment, the mahjong tiles are pressed by the mahjong tiles 5, so that the shuffling tiles 5 can move along with the big shuffling tray 1, and the relative movement between the sucker tiles and the mahjong tiles is less, and the noise is also low.

Then the other motor drives the worm 44 to rotate, the worm 44 drives the worm wheel 43 to rotate, and the worm wheel 43 drives the driving rotating shaft 41 to rotate. The slider 332 is slowly raised along the track of the elevation slot 42. The connection rod 331 drives the lifting slider 33 to rise along the guide rod 32. During the rising process, the mahjong pieces slowly enter the tile sucking area 22 and then are folded by the tile folding device to enter the tile lifting plate.

When the slider 332 rises to the highest position along the track of the lifting groove 42, the limit projection 34 and the catch groove 51 cooperate with each other to prevent the shuffling claw 5 from rotating. Since the limit protrusions 34 are circumferentially distributed, preferably four limit protrusions 34 are formed in a triangular cross section. Thus, even when the limit projection 34 and the locking groove 51 are not corresponding to each other, the two can be automatically adjusted to the locking position. When the shuffling claw 5 cannot rotate and the large shuffling tray 1 still rotates, the mahjong pieces are slowly pushed into the shuffling area 22 by the shuffling claw 5. At this time, the number of mahjong pieces is small, and the generated noise is small.

After a round has ended, the slides 332 may again be shuffled as they descend to a minimum along the track of the elevator slot 42, and so forth. As the height is increased, enough cards can be washed under the condition that the diameter of the large shuffling tray 1 is reduced, the diameter of the card sucking tray 2 is also reduced, and the corresponding card lifting opening is closer to the center of the tabletop, so that the card pushing-free effect can be realized.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, or alternatives falling within the spirit and principles of the utility model.
