[0026] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0027] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0028] like Figure 1-3 The example shown is an embodiment provided by the utility model.

[0029] The present invention provides a shuffling machine, comprising: a body 10, a card bin 20, a card feed channel 30 and a shuffling mechanism 40. The card bin 20 is arranged inside the body 10 and is used to store shuffled playing cards. Two card feed channels 30 are respectively arranged on opposite sides of the body 10 and are connected to the card bin 20. Playing cards to be shuffled can enter the card bin 20 from the card feed channels 30. The shuffling mechanism 40 is arranged at the bottom of the card feed channel 30 and is used to shuffle the playing cards to be shuffled in the card feed channel 30. Specifically, the shuffling mechanism 40 includes a driving motor 41, a worm gear 42, a worm 43 and a shuffling roller 44. The output shaft of the driving motor 41 is coaxially connected to the worm 43. The worm 43 is meshed with the worm gear 42. The worm gear 42 is coaxially connected to the shuffling roller 44. The shuffling roller 44 is parallel to the card feeding channel 30 and close to the inner end of the card feeding channel 30. The top of the shuffling roller 44 passes through the bottom wall of the card feeding channel 30 upwards and can contact the bottom surface of the playing cards stacked in the card feeding channel 30. The driving motor 41 drives the worm 43 to rotate. The worm gear 42 drives the shuffle roller 44 to rotate. The shuffle roller 44 is made of a material with a large friction coefficient, such as rubber, silicone, etc., or the surface of the shuffle roller 44 is covered with a coating layer with a large friction coefficient. When the shuffle roller 44 rotates, the friction between the shuffle roller 44 and the bottom surface of the playing cards is used to drive the playing cards to move. The two shuffle rollers 44 are symmetrical to each other. By controlling the two drive motors 41, the playing cards in the two card entry channels 30 can be alternately sent into the card bin 20 to achieve the effect of shuffling the playing cards. After the above-mentioned shuffler is adopted, the drive motor 41 drives the worm 43 and drives the worm gear 42 to rotate, so that the shuffle roller 44 and the worm gear 42 rotate coaxially, and the playing cards in the card entry channel 30 are sent into the card bin 20. The drive motor 41 is perpendicular to the axial direction of the shuffle roller 44, which reduces the axial span and occupied space of the two, which is conducive to the miniaturization of the shuffler.

[0030] Specifically, the card warehouse 20 is provided with a card inlet 21, the length of which is adapted to the length of a conventional playing card, the card inlet 21 is located at the inner end of the card inlet passage 30, the lower edge of the card inlet 21 is provided with two gaps 211, and a shuffling roller 44 is provided in each of the two gaps 211, the two shuffling rollers 44 are coaxially connected, and the contact area with the bottom surface of the playing card is increased by the two shuffling rollers 44, thereby increasing the friction between the two shuffling rollers 44 and the bottom surface of the playing card, which can improve the efficiency of card inlet. In addition, a baffle 212 is provided at the upper edge of the card inlet 21, the baffle 212 is spaced apart from the shuffling roller 44, the baffle 212 is located directly above the shuffling roller 44, and the interval width between the baffle 212 and the shuffling roller 44 is greater than the thickness of a conventional playing card and less than the thickness of two conventional playing cards, so as to avoid the situation where multiple playing cards are issued at one time due to friction and adhesion between the playing cards.

[0031] Furthermore, the bottom wall of the card entry channel 30 is tilted, and the inner end of the bottom wall of the card entry channel 30 is lower than the outer end thereof, so that the playing cards placed in the card entry channel 30 will automatically slide toward the card entry port 21, making it more convenient to enter the cards.

[0032] Furthermore, a flap 31 is hingedly connected to the outer end of the card entry passage 30, and the flap 31 is flipped and covered with the card entry passage 30. When the flap 31 is opened, it can be used to stack more playing cards, and when the flap 31 is closed, it can prevent debris from falling into the card compartment 20 from the card entry port 21. The outer wall of the flap 31 is curved, and when the angle of the flap 31 is fully opened, the outer wall of the flap 31 abuts against the side wall of the body 10, and the inner wall of the flap 31 is just flush with the bottom wall of the card entry passage 30, so that the playing cards stacked on the inner wall of the flap 31 can slide smoothly and unimpeded onto the bottom wall of the card entry passage 30, and then slide into the card entry port 21.

[0033] Specifically, a block 32 is provided on one side of the inner wall of the flip cover 31 away from its hinge axis, and a slot 33 is provided on the side wall of the card input channel 30. The block 32 is engaged with the slot 33, so that when the flip cover 31 is closed on the card input channel 30, the connection between the flip cover 31 and the card input channel 30 is more stable and will not be easily knocked open.

[0034] Specifically, a card taking port 11 is provided on one side wall of the body 10, and the card taking port 11 is connected to the card bin 20, so that the user can take out the shuffled playing cards in the card bin 20. A clearance port 22 is provided on the bottom wall of the card bin 20 near the card taking port 11, so that the user can pinch the end of the playing cards to apply force and take out the shuffled playing cards.

[0035] Specifically, an observation window 12 is provided on the top of the machine body 10, through which the situation in the card bin 20 can be seen, so that the participants of the poker game can supervise the shuffling process when the shuffler is shuffling the cards.

[0036] Obviously, the embodiments described above are only some embodiments of the utility model, rather than all embodiments. The preferred embodiments of the utility model are given in the accompanying drawings, but they do not limit the patent scope of the utility model. The utility model can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the utility model more thorough and comprehensive.
