Detailed implementation manners

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs; the terms used in the description of the present application in the specification are only for the purpose of describing specific embodiments and are not intended to limit the present utility model; the terms "including" and "having" and any variations thereof in the specification and claims of the present utility model and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the specification and claims of the present utility model or the above drawings are used to distinguish different objects and not to describe a specific order.

[0026] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present utility model. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

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

[0028] As Figures 1-4 shown, it is an embodiment provided by the present utility model.

[0029] An embodiment of the present utility model provides a card feeding mechanism for a card shuffler, including: a driving motor 10, a first friction roller 20, and a second friction roller 30. The driving motor 10 is drivingly connected to the first friction roller 20, and the first friction roller 20 is drivingly connected to the second friction roller 30. The first friction roller 20 and the second friction roller 30 can be made of materials with relatively strong friction or have their surfaces covered, such as rubber, silicone, etc., or a viscous substance can be directly coated on the roller surfaces. Among them, the first friction roller 20 and the second friction roller 30 are arranged in parallel, capable of forming a stable support for the bottom surface of the playing cards and coming into contact with each other to form friction. The linear speeds of the first friction roller 20 and the second friction roller 30 are equal. The first friction roller 20 is used to transport the playing cards to the second friction roller 30, and the second friction roller 30 is used to convey the playing cards out of the card shuffler, capable of synchronously and smoothly sending the playing cards out of the card shuffler, avoiding affecting the conveying efficiency or causing the playing cards to bend due to inconsistent conveying distances of the first friction roller 20 and the second friction roller 30 within the same time.

[0030] Specifically, an output shaft of the driving motor 10 is coaxially connected to a driving gear 11, the first friction roller 20 is coaxially connected to a double gear 21, and the second friction roller 30 is coaxially connected to a driven gear 31. The driving gear 11 is drivingly connected to one end of the double gear 21 through a first transmission belt 22, and the other end of the double gear 21 is drivingly connected to the driven gear 31 through a second transmission belt 32. It can be understood that the double gear 21 in this embodiment is formed by coaxially connecting two identical gears. The first transmission belt 22 and the second transmission belt 32 are both gear belts. The driving motor 10 drives the driving gear 11 to rotate. The driving gear 11 drives the double gear 21 to rotate through the transmission of the first transmission belt 22. The double gear 21 drives the first friction roller 20 to rotate on the one hand, and also drives the driven gear 31 to rotate simultaneously through the second transmission belt 32 on the other hand. The driven gear 31 then drives the second friction roller 30 to rotate, thereby achieving the purpose of driving the first friction roller 20 and the second friction roller 30 simultaneously with one driving motor 10.

[0031] Furthermore, the outer diameters of the first friction roller 20 and the second friction roller 30 are equal, and the diameters, tooth numbers, and rotational speeds of the double gear 21 and the driven gear 31 are equal, enabling the double gear 21 and the driven gear 31 to rotate synchronously and coordinately under the drive of the driving gear 11, and further driving the first friction roller 20 and the second friction roller 30 to rotate synchronously and having the same linear speed.

[0032] Specifically, the first friction roller 20 is located between the second friction roller 30 and the card - issuing port 41 of the card - dealing machine and is close to the card - issuing port 41 of the card - dealing machine. The second friction roller 30 is higher than the first friction roller 20, making the rear end of the transported playing cards higher than the front end, which is conducive to more smoothly sending out the cards from the card - issuing port 41. In addition, in order to increase the friction force on the bottom surface of the playing cards, the length of the second friction roller 30 is longer than that of the first friction roller 20, and its length is close to the width of the playing cards, having a larger contact area with the bottom surface of the playing cards. A number of anti - slip strips 33 are evenly distributed along the circumferential direction of the side wall of the second friction roller 30, which can further increase the friction force with the playing cards.

[0033] Further, a pressure roller 23 is arranged at an interval above the first friction roller 20. The pressure roller 23 is parallel to the first friction roller 20. The interval between the first friction roller 20 and the pressure roller 23 is greater than the thickness of a regular playing card and less than twice the thickness of a regular playing card, avoiding the situation where playing cards rub against and stick to each other, resulting in multiple playing cards being dealt at one time.

[0034] The present utility model also proposes: a card - dealing machine, including a card bin 40 and the card - sending mechanism of the card - dealing machine. The card bin 40 is the main part of the card - dealing machine for storing playing cards. The first friction roller 20 and the second friction roller 30 are respectively arranged in parallel below the card bin 40, and the side walls of the first friction roller 20 and the second friction roller 30 both penetrate upward through the bottom wall of the card bin 40, enabling the playing cards in the card bin 40 to respectively contact the first friction roller 20 and the second friction roller 30. In one embodiment, a shuffling mechanism can also be selected to be arranged at the card - feeding port of the card bin 40. The shuffling mechanism includes friction rollers, motors, and worm and worm - gear mechanisms respectively arranged at two card - feeding ports. By driving the worm and worm - gear to rotate with the motor and then transmitting the rotation to the friction rollers to drive the friction rollers to rotate, during the rotation of the friction rollers, the playing cards are sent into the card - feeding port by using the friction force between the friction rollers and the bottom surface of the playing cards, and by controlling the two motors on both sides, the playing cards at the two card - feeding ports can be alternately sent into the card bin 40 in sequence to achieve the effect of shuffling.

[0035] Specifically, a card - issuing port 41 is opened on a side wall of the card bin 40 close to the second friction roller 30. The height of the card - issuing port 41 is adapted to the height of the second friction roller 30, facilitating the playing cards to extend out from the card - issuing port 41.

[0036] Further, a base 42 is arranged at the bottom of the card bin 40. The base 42 is rotatably connected to the card bin 40, enabling the card - issuing port 41 to turn to different directions for dealing cards.

[0037] Obviously, the embodiments described above are only a part of the embodiments of the present utility model, rather than all of the embodiments. The preferred embodiments of the present utility model are shown in the accompanying drawings, but they do not limit the patent scope of the present utility model.

On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosed content of the present utility model more thorough and comprehensive.

Any equivalent structure directly or indirectly using the content of the specification and drawings of the present utility model in other related technical fields shall be within the scope of the patent protection of the present utility model by the same token.
