the front end of the card feeding mechanism 40 extends into the roller 30 through the notch 261 of the front cover plate 26, so that the card feeding mechanism 40 is positioned at the top end in the roller 30, the high side plate 42 is kept out of contact with the roller 30, and the mahjong tiles 10 driven by the magnet assembly 34 of the roller 30 can pass through the low side plate 43 and be blocked by the high side plate 42 to be separated from the suction force of the magnet assembly 34 and fall onto the conveyer belt 44 to be conveyed out; by the above structure, the mahjong tiles 10 can be output one by one in the roller 30, thereby achieving the effects of automatic shuffling and tile feeding and reducing manual intervention.

The composition of the invention is explained in detail as follows: as shown in fig. 1 to 6, the components of the present invention contacting the mahjong tiles 10 are made of non-magnetic materials, so as to prevent the internal magnet 11 of the mahjong tiles 10 from attracting external objects to affect the shuffling and transportation of the mahjong tiles 10, and the internal magnet 11 is biased to the top surface of the mahjong tiles 10, so that the top surface of the mahjong tiles 10 has magnetic force and the bottom surface has no magnetic force; the inner magnets 11 of any mahjong tile 10 are arranged to have the same magnetic poles at the upper and lower sides, and the top surfaces of any two mahjong tiles 10 are close to each other to generate repulsion by the principle of opposite attraction and same polarity repulsion, thereby being capable of helping to shuffle more uniformly. Similarly, the centripetal surface of the magnet 342 of the magnet assembly 34 is set to have different magnetic poles from the top surface of the inner magnet 11, so that the magnet assembly 34 can attract the mahjong tile 10 and bring the mahjong tile 10 to the top, the tile surface of the mahjong tile 10 can face downwards, when the mahjong tile 10 is blocked by the high side plate 42 and falls on the conveyer belt 44, the tile surface of the mahjong tile 10 is in a downward covering state and cannot be peeped, and most of the mahjong tile 10 can fall on the conveyer belt 44 longitudinally due to the attraction of the magnet assembly 34 in the long axis direction; moreover, the smooth sheet 421 is made of Teflon material, and has a very low friction coefficient and a smooth function, so that one side of the mahjong tile 10 is abutted against the smooth sheet 421 and has an effect of reducing friction force in the process of conveying by the conveying belt 44.

Referring to fig. 1 to 6, when the present invention is used, a plurality of mahjong tiles 10 are placed in the roller 30, the first motor 27 drives the first transmission belt 28 to drive the roller 30 to rotate, the inclined guide plate 35 rotates the mahjong tiles 10 to generate an inclined displacement and stir after the roller 30 rolls, so as to achieve a uniform shuffling function, the magnet assembly 34 around the roller 30 and the inner magnet 11 of the mahjong tiles 10 attract each other to suck up the mahjong tiles 10 from the bottom, and the rolling condition of the roller 30 is detected through the magnetic reed switch 29, if the rotation is abnormal (the frequency of the magnet assembly 34 passing through the magnetic reed switch 29 is in an error range), it is determined that a rotation obstacle may occur, at this time, even if the first motor 27 rotates reversely for a set distance, the rotation continues, so as to eliminate the obstacle. After the mahjong tiles 10 are sucked up by the shuffling mechanism 20, the mahjong tiles 10 are blocked by the high side plate 42 and then fall onto the conveyer belt 44, the conveyer belt 44 is driven by the second motor 441 to stably convey the mahjong tiles 10 forward, and the tension of the conveyer belt 44 can be adjusted by adjusting the position of the tension wheel 445 in the inclined groove 446.

Referring to fig. 5 to 6, the distance between the edge of the guiding wheel 45 and the high side plate 42 and the width of the outlet 461 of the guiding plate 46 are both greater than the length of the mahjong tile 10 in the short axis direction but less than the length of the mahjong tile 10 in the long axis direction; therefore, if the mahjong tiles 10 are conveyed and advanced in the transverse direction (as shown in fig. 6), one end of the mahjong tile 10 is blocked by the guiding wheel 45 to change the direction, and the mahjong tile 10 is driven by the guiding wheel 45 in the direction opposite to the advancing direction of the conveying belt 44, so that the mahjong tile 10 is easier to be guided and the mahjong tile 10 is output on the conveying belt 44 longitudinally through the guiding plate 46, thereby achieving the effect of automatically correcting the direction.

The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. The equivalent substitution or change made by the technical personnel in the technical field on the basis of the invention is all within the protection scope of the invention. The protection scope of the invention is subject to the claims.
