[0078] Embodiment 1

[0079] As Figures 1-11 shown, a shuffling machine includes: a base 100, a first shuffling body 200, a second shuffling body 300, a card-cutting mechanism 400, and a card-pushing mechanism 500.

[0080] Among them, the base 100 includes a first position and a second position.

[0081] Among them, the first shuffling body 200 is connected to the base 100 in a liftable manner, and the first shuffling body 200 can rise to the first position or descend to the second position.

[0082] Specifically, when the first shuffling body 200 is in the first position, it is higher than the second shuffling body 300, and when the first shuffling body 200 is in the second position, it is lower than the second shuffling body 300.

[0083] Among them, the number of the second shuffling bodies 300 is two, and both of the two second shuffling bodies 300 are connected to the base 100, and the two second shuffling bodies 300 are respectively located on both sides of the first shuffling body 200.

[0084] Among them, the card cutting mechanism 400 is located on the first shuffling body 200. When the first shuffling body 200 is in the first position, the card cutting mechanism 400 is used to drive a single playing card located on the first shuffling body 200 to move towards one of the two second shuffling bodies 300.

[0085] Among them, the number of the card pushing mechanisms 500 is two, and the two card pushing mechanisms 500 are respectively located on the two second shuffling bodies 300. When the first shuffling body 200 is in the second position, both of the two card pushing mechanisms 500 are used to drive all the playing cards located on the second shuffling body 300 to move towards the first shuffling body 200.

[0086] Specifically, in terms of the working principle, the first shuffling body 200 first rises to the first position; then the card cutting mechanism 400 alternately transfers any number of playing cards from one to three located on the first shuffling body 200 to the two second shuffling bodies 300 until the first shuffling body 200 is completely emptied; then the first shuffling body 200 descends to the second position; then the card pushing mechanism 500 in one of the second shuffling bodies 300 transfers all the playing cards in the second shuffling body 300 to the first shuffling body 200, and the card pushing mechanism 500 in the other second shuffling body 300 transfers all the playing cards in the second shuffling body 300 to the first shuffling body 200; the above operations are cycled for a predetermined number of times.

[0087] In this embodiment, through the organic combination of the card cutting mechanism 400 and the card pushing mechanism 500, the two shuffling operations of single cut separation and stack cut combination can be realized, simulating hand washing with a mechanical mechanism, improving the functionality and practicality of the shuffling machine, and enhancing the working efficiency and reliability.

[0088] It is also worth noting here that the card pushing mechanism 500 can transfer all the playing cards in the second shuffling body 300 to the first shuffling body 200 at one time, greatly increasing the shuffling efficiency.

[0089] As Figures 1-11 shown, on the basis of the above embodiment, the card cutting mechanism 400 includes a first driving element 410 and a friction wheel 420.

[0090] Among them, the first driving element 410 is connected to the first shuffling body 200;

[0091] Among them, the number of the friction wheels 420 is two. The two friction wheels 420 are respectively located on both sides of the first shuffling body 200. The friction wheels 420 are rotatably connected to the first shuffling body 200, and the friction wheels 420 are connected to the first driving element 410. The first driving element 410 can drive the friction wheels 420 to rotate.

[0092] It should be noted here that the number of the first driving elements 410 can be one or two. When the number of the first driving elements 410 is one, the two friction wheels 420 are both connected to the first driving element 410 through a transmission mechanism, and one first driving element 410 drives the two friction wheels 420 to rotate simultaneously through the transmission mechanism. When the number of the first driving elements 410 is two, the two friction wheels 420 are respectively connected to the two first driving elements 410, and the two first driving elements 410 respectively drive the two friction wheels 420 to rotate.

[0093] In this embodiment, the connection between the friction wheels 420 and the first driving element 410 can accurately control the moving direction and speed of a single playing card, ensuring the accuracy of each card cutting operation.

The first gear 431 is connected to the first driving element 410, and the first driving element 410 can drive the first gear 431 to rotate.

[0096] In addition, the first driving element 410 is a motor.

[0097] In this embodiment, the two friction wheels 420 are both connected to the first driving element 410 through the transmission gear set 430. The first driving element 410 drives the two friction wheels 420 to rotate simultaneously through the first gear 431, so as to respectively realize the function of driving a single playing card located on the first shuffling body 200 to move towards the two second shuffling bodies 300 through the forward and reverse rotations of the first driving element 410, saving space.

[0098] As Figures 1-11 shown, on the basis of the above embodiment, the second shuffling body 300 includes:

[0103] Specifically, the second driving element 510 is not specifically limited and can be a cylinder, an electric cylinder, a hydraulic cylinder, or can be a linear module.

[0104] In this embodiment, the card pushing cavity 310 and the driving cavity 320 are separated by the card supporting plate 330, so that each functional part is independent, reducing mutual interference and making the whole mechanism more compact. By driving the card pushing plate 520 to move through the second driving element 510, the operation of automatic card pushing is realized, improving the working efficiency.
