[0024] As Figures 1-5The utility model discloses a shuffling machine, including shuffling machine body 1, this shuffling machine body 1 includes shell seat 12, is provided with playing card containing bin 11 in shell seat 12, in this embodiment, the playing card containing bin 11 is formed by the integral setting of shell seat 12, and the upper and lower sides and the front side of playing card containing bin 11 are open, and its upper side opening is linked with the shuffling mouth 23 and communicates. Meanwhile, on shell seat 12 and located playing card containing bin 11's top is provided with two groups of shuffling mechanism 2 for pushing playing card staggered and falls into playing card containing bin 11, and two groups of shuffling mechanism 2 are oppositely arranged. Still be provided with control circuit board 7 in shell seat 12, control circuit board 7 is electrically connected with shuffling mechanism 2, and moreover the top of shell seat 12 is correspondingly provided with two button 8 with two touch keys on control circuit board 7 contact connection, to control the switch of shuffling machine and shuffling operation through button 8, and the control circuit board 7 is electrically connected with charging interface 9, and the charging interface 9 is used to charge the battery (not shown in the drawing) of setting in shell seat 12. In addition, the mode of ordinary battery replacement can also be used, so that the charging interface does not need to be set.

[0025] Two card supporting plates 22 are oppositely arranged on the top of the card accommodating bin 11 and are connected with the shell base 12 by screws or buckles, and a card shuffling opening 23 is formed on the shell base 12 at a position corresponding to the inner side of each card supporting plate 22. Specifically, the two card shuffling openings 23 are symmetrically arranged on the left and right sides of the card accommodating bin 11. A set of card shuffling mechanism 2 is installed on the shell base 12 at a position corresponding to each card shuffling opening 23, and a card supporting plate 22 is arranged on each set of card shuffling mechanism 2 and is inclined from outside to inside and from top to bottom, that is, the outside is high and the inside is low, so that the cards placed on the card supporting plate 22 can stably slide towards the card shuffling opening 23 and will not scatter outward. In this embodiment, each set of card shuffling mechanism 2 is composed of a card shuffling conveying wheel 24 and a set of fan-shaped wheel auxiliary mechanism 21, each set of fan-shaped wheel auxiliary mechanism 21 is provided with three fan-shaped wheels, and the three fan-shaped wheels are arranged in a triangular shape. The card shuffling conveying wheel 24 and the three fan-shaped wheels on each set of card shuffling mechanism 2 are synchronously rotated by means of linkage gears and rotating shafts. Moreover, two of the fan-shaped wheels are small fan-shaped wheels 211, and the remaining one is a large fan-shaped wheel 212, that is, the radius of the small fan-shaped wheel 211 is smaller than that of the large fan-shaped wheel 212. The two small fan-shaped wheels 211 are arranged near the position of the card shuffling opening 23 and are coaxially connected with the card shuffling conveying wheel 24 through rotating shafts 25 on the left and right sides of the card shuffling conveying wheel 24, and the large fan-shaped wheel 212 is arranged on the outside of the card shuffling conveying wheel 24 and is drivingly connected with the card shuffling conveying wheel 24 through linkage gears 26. Of course, the two small fan-shaped wheels 211 can also be drivingly connected with the card shuffling conveying wheel 24 through gears, as long as the synchronous rotation of the two small fan-shaped wheels 211, the card shuffling conveying wheel 24 and the large fan-shaped wheel 212 is ensured. Meanwhile, a through hole 221 is formed on each card supporting plate 22 at a position corresponding to the two small fan-shaped wheels 211, the card shuffling conveying wheel 24 and the large fan-shaped wheel 212, and the two small fan-shaped wheels 211 and the large fan-shaped wheel 212 are respectively arranged in the through holes 221 at their corresponding positions and will intermittently protrude upwards from the upper side of the card supporting plate 22 by a certain height during rotation to push the cards into the card shuffling opening 23. Since each set of card shuffling mechanism 2 adopts three fan-shaped wheels, when each fan-shaped wheel rotates and intermittently protrudes upwards from the upper side of the card supporting plate 22, it can promote the up-and-down shaking of the cards and make the cards more loose, so that the adsorption and adhesion between the cards are avoided, thereby preventing the card stacking conveying and improving the shuffling accuracy. Moreover, since two of the three fan-shaped wheels are arranged near the position of the card shuffling opening 23, in order to ensure that the cards can be smoothly sent into the card shuffling opening 23 while being shaken, the two fan-shaped wheels near the card shuffling opening 23 are arranged as small fan-shaped wheels 211, and the fan-shaped wheel on the outside of the card shuffling opening 23 is arranged as a large fan-shaped wheel 212, so that the shaking amplitude of the cards on the outside is larger and the shaking amplitude of the cards on the inside is smaller, thereby avoiding the problem that the cards are not easily sent into the card shuffling opening 23 due to excessive shaking.Moreover, the three fan-shaped wheels are arranged in a triangle shape, and the three fan-shaped wheels are synchronously pushed from three positions, so that the transmission of the playing cards is stable. In addition, the large fan-shaped wheel 212 can be provided as a fan-shaped gear, or the three fan-shaped wheels are provided as fan-shaped gears, so that the friction between the fan-shaped wheels and the playing cards is increased through the teeth on the fan-shaped wheels, and the playing cards will not slip during the pushing process, and the shuffling effect is further improved. In order to make the transmission of the playing cards more smooth, an arc-shaped protrusion 13 is arranged above the two small fan-shaped wheels 211.

[0026] The shuffling transmission wheel 24 is arranged at the middle position of the shuffling opening 23, and a rotating wheel type shuffling limiting mechanism 5 is arranged above the shuffling transmission wheel 24. Specifically, the rotating wheel type shuffling limiting mechanism 5 includes a mounting seat 51, a connecting shaft 52 arranged on the mounting seat 51, and a card limiting wheel 53 sleeved on the connecting shaft 52, and the inner hole diameter of the card limiting wheel 53 is slightly larger than the outer diameter of the connecting shaft 52, so that the card limiting wheel 53 can rotate and move up and down on the connecting shaft 52. At this time, the mounting seat 51 is fixed on the shell seat 12 through a screw, and at this time, a slot 121 is formed on the shell seat 12 at the position corresponding to the mounting seat 51, and the card limiting wheel 53 is rotatably arranged in the slot 121. Since the card limiting wheel 53 is arranged above the shuffling transmission wheel 24 and cooperates with the shuffling transmission wheel 24, a limiting gap is formed between the rotatable card limiting wheel 53 and the shuffling transmission wheel 24, so that the purpose of limiting the over-card space during shuffling is achieved, the playing cards are always in full contact with the shuffling transmission wheel 24, and the phenomenon of sticking and slipping does not occur, and the purpose of limiting the number of over-cards during shuffling is achieved, and the shuffling is as much as one by one as possible, so that the problem of the shuffling cards sticking and adding into the shuffling opening 23 is avoided, so that the shuffling smoothness is effectively improved, and each shuffling is more uniform and complete. Since the card limiting wheel 53 is arranged above the middle position of the shuffling opening 23, and there is enough space at both ends of the card limiting wheel 53, even if the playing cards are bent, they can be smoothly and accurately transmitted into the shuffling opening 23, and the problem of jamming during shuffling is avoided. Moreover, since the card limiting wheel 53 can move up and down by a certain distance, the transmission of playing cards of different thicknesses can be realized through the card limiting wheel 53, so that the application range is greatly improved, and the use demand of the players can be better met.

[0027] In the embodiment, the two sets of shuffling mechanisms 2 are driven by the same motor 27, and the control circuit board 7 is electrically connected with the shuffling mechanisms 2, i.e. electrically connected with the motor 27. Specifically, the two sets of shuffling mechanisms 2 are respectively connected with the power output gear of the motor 27 through a set of transmission gears 28. The motor 27 is fixedly installed on the shell base 12, each transmission gear 28 is rotatably connected in a box, and the box is installed on the shell base 12. Moreover, the two sets of shuffling mechanisms 2 are assembled in opposite angles in the rotation direction, so that when the motor 27 drives the two sets of shuffling mechanisms 2 to rotate synchronously, the cards placed on the two card receiving plates 22 can be staggeredly dropped into the card storage compartment 11 through the shuffling openings 23 to complete the shuffling. Since the same motor 27 is used to drive the shuffling, the speed consistency of the two sides of the shuffling can be achieved, so that the shuffling is more uniform and the shuffling effect is better. In addition, a hand crank connected with the transmission gear 28 can also be used to realize the synchronous rotation of the two sets of shuffling mechanisms 2 by cranking, and in this case, the control circuit board does not need to be set.

[0028] In the embodiment, a card plate adjusting and limiting mechanism 3 or a screw rod adjusting and limiting mechanism 4 is arranged on the shell base 12 and horizontally placed in front of the two card receiving plates 22. The card plate adjusting and limiting mechanism 3 or the screw rod adjusting and limiting mechanism 4 can not only position the cards on the card receiving plates 22 to prevent the cards from scattering from the side, but also adjust the use distance of the card receiving plates 22 in the length direction of the cards, so that the shuffling operation can be adapted to cards of different lengths, such as conventional cards and international cards. In addition, an electric adjusting and limiting mechanism can also be arranged to realize the adjustment of the length space of the cards.

[0029] Specifically, when the card plate adjusting limiting mechanism 3 is arranged, the card plate adjusting limiting mechanism 3 comprises a positioning baffle 31, a plurality of fixed connecting rods 32 fixedly connected to the positioning baffle 31 and a limiting card plate 33 detachably connected to the fixed connecting rods 32. The plurality of fixed connecting rods 32 are evenly divided into two groups and arranged in left-right symmetry. In this embodiment, four fixed connecting rods 32 are arranged, and each fixed connecting rod 32 is a square rod. Two fixed connecting rods 32 on the same side are arranged in up-down symmetry. Connection holes are arranged on the shell seat 12 for the fixed connecting rods 32 to pass through and be fixed. A clamping groove 331 downwardly opening is arranged on the limiting card plate 33. The number of the clamping grooves 331 is the same as that of the fixed connecting rods 32, and the positions correspond, that is, one clamping groove 331 can be clamped on one fixed connecting rod 32. When the limiting card plate 33 is clamped on the fixed connecting rods 32 on the inner side of the positioning baffle 31, at this time, the paper cards with a shorter length can be placed on the card receiving plate 22. When the limiting card plate 33 is taken out, the paper cards with a longer length can be placed on the card receiving plate 22. At the same time, limiting stop blocks 222 can also be arranged on the outer sides of the card receiving plates 22 away from the card shuffling opening 23. Through the limiting card plate 33, the adjustment of the length of the paper cards placed on the card receiving plate 22 can be more quickly and conveniently and accurately realized.

[0030] When the screw adjusting limiting mechanism 4 is set, the screw adjusting limiting mechanism 4 comprises a limiting baffle 41, an adjusting screw 42 arranged on the limiting baffle 41 and a plurality of sliding connecting rods 43. The connecting hole for the sliding connecting rod 43 and the adjusting screw 42 is arranged on the shell base 12. One end of each sliding connecting rod 43 is fixed on the limiting baffle 41, and the other end is movably connected with the connecting hole. The adjusting screw 42 is threadedly connected with the connecting hole. When the adjusting screw 42 is twisted by the knob 44 at the outer end of the adjusting screw 42, the limiting baffle 41 can be moved inward or outward, so as to adjust the use distance of the card supporting plate 22 in the length direction of the card. At this time, there are two control modes. One is that the adjusting screw 42 is threadedly connected with the shell base 12, so that the adjusting screw 42 can move along the axial direction when it is twisted, thereby driving the limiting baffle 41 to move. The other is that the adjusting screw 42 is threadedly connected with the limiting baffle 41, so that the limiting baffle 41 moves along the axial direction of the adjusting screw 42 by twisting the adjusting screw 42. In addition, the plurality of sliding connecting rods 43 are divided into two groups and symmetrically arranged on both sides of the adjusting screw 42. In the embodiment, a total of four sliding connecting rods 43 are arranged, and each sliding connecting rod 43 is a square rod. The two sliding connecting rods 43 on the same side are arranged in an upper and lower manner. Of course, the sliding connecting rods 43 can also be arranged in other numbers, and can be triangular, rhombic, etc. Since the movement of the limiting baffle 41 is realized by the adjusting screw 42, the reliability of the connection is improved. Even if the shuffler tilts to the side of the limiting baffle 41, the limiting baffle 41 will not fall off, and the space for position adjustment is larger.

[0031] In order to make the washed cards convenient and fast to take out, the card supporting plate 6 is arranged at the bottom of the card accommodating bin 11, and the card supporting plate 6 is push-pull connected on the shuffler body 1. Specifically, two slide grooves 122 are symmetrically arranged on the bottom of the shell base 12, and the card supporting plate 6 is slidably inserted between the two slide grooves 122. Moreover, in the embodiment, the card supporting plate 6 is arranged in an L-shaped structure, and the long side of the L-shaped structure is connected with the slide groove 122, so as to close the lower side opening of the card accommodating bin 11. The short side of the L-shaped structure is arranged to block the front side opening of the card accommodating bin 11, and the upper part thereof is arranged in an arc structure which is reduced inward from both sides, so as to facilitate the pulling operation of the card supporting plate 6. At the same time, a plurality of convex strips 61 are arranged on the card supporting plate 6. Specifically, the convex strips 61 are arranged on the inner surface of the card supporting plate 6 and located in the lower side opening of the card accommodating bin 11, so that a gap is formed between the card and the inner surface of the card supporting plate 6. The lowest card will not be adsorbed on the inner surface of the card supporting plate 6, so as to ensure the smooth taking of the card.
