[0029] In this embodiment, during use, two stacks of playing cards are placed on the card feeding member 3, and the top of the playing cards is pressed down by the elastic card pressing member 5 to ensure that the playing cards at the bottom are in close contact with the elastic card pressing member 5. The through groove 6 is used to accommodate the card feeding wheel member 6a. When shuffling the cards, the two card feeding wheels 6a are staggered to feed the playing cards one by one into the card receiving chamber 30 in the card receiving frame 2, so as to achieve alternating shuffling and uniform shuffling, and no cards will be missed during the shuffling process, thereby reducing the failure rate and having a high degree of automation.

[0030] Combination Figure 1-6 As shown, the card feeding wheel component 6a includes a first card feeding roller 7 and a second card feeding roller 8 arranged at the bottom of the card feeding component 3, the axis line of the first card feeding roller 7 and the axis line of the second card feeding roller 8 coincide with each other, and the outer rings of the first card feeding roller 7 and the second card feeding roller 8 have a protruding structure 9.

[0031] Specifically, when shuffling the cards, the first card feeding roller 7 and the second card feeding roller 8 rotate synchronously, cooperate with the raised structure 9 to make close contact with the bottom surface of the lowest playing card, and feed the lowest playing card into the card receiving frame 2, thereby achieving alternating shuffling and uniform shuffling.

[0032] The raised structure 9 includes a plurality of card feeding protrusions 10 and tooth-shaped portions 11 arranged at the outer rings of the first card feeding roller 7 and the second card feeding roller 8. The card feeding protrusions 10 and tooth-shaped portions 11 are respectively distributed in a circular array along the axis of the first card feeding roller 7 and the second card feeding roller 8. The height of the card feeding protrusions 10 is higher than the height of the tooth-shaped portions 11.

[0033] In this embodiment, during the shuffling and feeding process, the card feeding protrusion 10 and the toothed portion 11 can ensure the contact area with the playing cards, ensuring that the playing cards can be smoothly fed into the card receiving frame 2, achieving alternating shuffling and uniform shuffling. The card feeding protrusion 10 and the toothed portion 11 are respectively distributed in a circular array along the axis of the first card feeding roller 7 and the second card feeding roller 8. The height of the card feeding protrusion 10 is higher than the height of the toothed portion 11, reducing the probability of card feeding failure.
