Two card receiving frame 40 with two card inlets 30 corresponding connection, and the card receiving frame 40 is used for stacking the playing cards of waiting for washing, and the inner end of the card receiving frame 40 is connected with the card inlet 30, and the playing cards of waiting for washing can be slid into the card storehouse 20 from the card receiving frame 40 through the card inlet 30. Specifically, the bottom of the card receiving frame 40 is provided with a driving motor 41, the driving motor 41 does not need to select a speed reducer, and a general motor can be selected, which can reduce the cost. The inner end of the card receiving frame 40 is provided with a shuffling roller 42, the roller surface of the shuffling roller 42 protrudes from the upper surface of the card receiving frame 40, and can contact the bottom surface of the playing cards stacked on the card receiving frame 40. The shuffling roller 42 generally includes a roller shaft and a roller surface, and the roller surface of the shuffling roller 42 is usually made of a material with a large friction coefficient, such as rubber or silicone. Alternatively, a coating layer with a large friction coefficient is coated on the surface of the shuffling roller 42. When the shuffling roller 42 rotates, it can move the playing cards by utilizing the friction between the shuffling roller 42 and the playing cards. The output shaft of the driving motor 41 is drivingly connected with a driving gear 43, and one end of the roller shaft of the shuffling roller 42 is drivingly connected with a driven gear 44. The driving gear 43 is engaged with the driven gear 44. The rotation of the output shaft of the driving motor 41 can sequentially drive the driving gear 43, the driven gear 44, and the shuffling roller 42 to rotate. The driving gear 43 and the driven gear 44 can be selected as basic spur gears. The diameter and the number of teeth of the two gears can be selected according to the required speed of the shuffling roller 42, which can more simply and directly improve the shuffling speed. The roller shaft of the shuffling roller 42 is perpendicular to the card feeding direction of the card inlet 30, and the two shuffling rollers 42 are symmetrically arranged. By controlling the two driving motors 41, the playing cards on the two card receiving frames 40 can be alternately fed into the card storehouse 20, achieving the effect of shuffling the playing cards. Moreover, the driving motor 41 and the shuffling roller 42 are close to the middle part of the card inlet 30, and the driving motor 41 is also close to the middle part of the shuffling roller 42, so that the driving motor 41 is within the length range of the shuffling roller 42. The output shaft of the driving motor 41 is parallel to the roller shaft of the shuffling roller 42, and the axial installation length of the shuffling roller 42 and the driving motor 41 does not need to be lengthened. At the same time, the driving motor 41 and the shuffling roller 42 are close to the bottom of the card receiving frame 40, which can reduce the longitudinal installation space. In addition, the driving gear 43 and the driven gear 44 simplify the transmission mechanism, greatly reducing the overall installation space, which is beneficial to the miniaturization and portability of the shuffler.

[0031] Further, the card holder 40 is obliquely arranged, the card holder 40 is a planar plate, the outer end of the card holder 40 is higher than the inner end of the card holder 40, and the upper surface of the card holder 40 is smooth, so that the playing cards placed on the card holder 40 automatically slide to the card inlet 30, and the card feeding is more convenient.

[0032] Specifically, the inner end of the card holder 40 is spaced apart to be provided with two mounting holes 45, and one shuffling roller 42 is arranged in each of the two mounting holes 45, so that the roller surface of the shuffling roller 42 can be exposed from the upper surface of the card holder 40, facilitating contact with the playing cards, and the two shuffling rollers 42 are coaxially connected, which can further increase the contact area between the roller surface of the shuffling roller 42 and the bottom surface of the playing cards, thereby improving the friction and the shuffling efficiency.

[0033] Further, the middle part of the upper edge of the card inlet 30 is provided with a pressing block 31, the upper end of the pressing block 31 is connected with a guide shaft 32, the guide shaft 32 is sleeved with a spring 33, the upper end of the spring 33 is connected with the inner wall of the machine body 10, the lower end of the spring 33 abuts against the upper end of the pressing block 31, and the lower end of the pressing block 31 is elastically spaced apart from the roller surface of the shuffling roller 42. When the pressing block 31 is subjected to upward extrusion force, the pressing block 31 will be raised upward, so that the spring 33 is contracted. When the upward extrusion force on the pressing block 31 decreases or disappears, the pressing block 31 will fall downward under the action of its own gravity and the elastic force of the spring 33. It can be understood that the pressing block 31 is located directly above the shuffling roller 42, and the spacing width between the pressing block 31 and the shuffling roller 42 is at least greater than the thickness of a regular playing card. The spacing between the pressing block 31 and the shuffling roller 42 after the pressing block 31 is lifted is generally not more than the thickness of three playing cards. This can not only reduce the situation that multiple playing cards are sent out at a time due to mutual friction and adhesion between the playing cards, thereby reducing the shuffling effect, but also avoid the shuffling roller 42 from being jammed due to the mutual adhesion of multiple playing cards.

[0034] Specifically, a card taking opening 11 is formed in one side wall of the machine body 10 and communicates with the card compartment 20. The card taking opening 11 and the card inlet 30 are located on different side walls of the machine body 10, and the horizontal width of the card taking opening 11 is smaller than that of the card inlet 30, so as to take the shuffling playing cards in the card compartment 20.
