TECHNICAL FIELD

[0001] The present application relates to the technical field of silent card dispenser, in particular to a silent card dispenser. BACKGROUND

[0002] As the most common entertainment supplies in people's life, playing cards are loved by the public because of their diverse playing methods and suitability for all ages. However, after a round of playing cards, players need to arrange, shuffle and deal cards by themselves. In order to save the time of dealing cards, various machines for replacing manual dealing have emerged, which greatly improves the experience of playing cards.

[0003] There are three parts in the implementation of the card dispenser on the market: card dispensing structure, rotation control and transmission mode.

[0004] In the existing transmission mode, the rubber wheel is fastened with the metal shaft, the shaft is assembled with the shaft sleeve in rolling, and the gap between the two is inevitable, which causes the friction between the shaft and the fixed shaft sleeve, the shaft shakes and shakes, increases the noise of the machine, especially in the case of multi-stage transmission, the noise is more obvious. CONTENT OF THE INVENTION

[0005] The present application overcomes at least one deficiency in the above problems and proposes a silent card dispenser.

[0006] The technical scheme adopted by the present application is as follows:

[0007] A silent card dispenser, comprising a card dispensing box and a card wheel transmission assembly installed on the card dispensing box, the card wheel transmission assembly comprising a card wheel, a fixed shaft and a bearing;

[0008] The card dispensing box has a support group, the support group comprising two supports arranged at intervals;

[0009] The axis of the card wheel is provided with a perforation, and the bearing is installed at the perforation of the card wheel;

[0010] The card wheel is sleeved on the fixed shaft through the corresponding bearing sleeve;

[0011] The two ends of the fixed shaft are fixed on the two supports of the support group.

[0012] The fixed shaft does not rotate, the card wheel is sleeved on the fixed shaft through the bearing, the sliding friction (between the wheel and the shaft sleeve) in the prior art is changed into rolling friction, so that the card wheel can hardly make sound when rotating, effectively improving the use experience.

[0013] In one embodiment of the present application, the two ends of the perforation are respectively provided with the bearing.

[0014] Such installation can ensure stable and reliable rotation of the card wheel.

[0015] In one of the embodiments of the utility model, the card wheel is provided with a rubber sleeve.

[0016] During operation, the card wheel contacts the cards through the rubber sleeve to exert force on the cards, and the rubber sleeve can effectively increase the friction with the cards.

[0017] In one of the embodiments of the utility model, the card wheel transmission assembly further comprises a motor, a gear is mounted on the motor, the card wheel is provided with a ring of teeth, and the first gear is engaged with the teeth.

[0018] In the prior art, the end of each metal shaft is clamped with a gear or a synchronous pulley, and 4 to 6 shafts are driven to rotate by a single motor. The transmission belt and the gear occupy the space on both sides of the card box, resulting in a large transverse volume of the machine. The single motor drives multiple shafts, which requires a large torque, resulting in a large weight of the machine and inconvenience in portability. The card wheel of the present application is directly engaged with the gear through the teeth, which reduces the transmission stages and provides conditions for reducing the overall volume of the card dispenser. In addition, the direct engagement of the card wheel with the gear enables the motor to directly drive the card wheel to rotate, without the need for a special multi-stage transmission system (noise is generated at multiple positions) as in the prior art card dispenser, effectively reducing noise.

[0019] In one of the embodiments of the utility model, the rubber sleeve of the card wheel has two groups, and the teeth are located between the two groups of rubber sleeves.

[0020] In one of the embodiments of the utility model, the two sides of the teeth of the card wheel are prismatic structures, and the rubber sleeve is elastically sleeved on the prismatic structures. This arrangement does not require the use of adhesive to fix the rubber sleeve.

[0021] In one of the embodiments of the utility model, the card wheel transmission assembly has two groups, one of which is a flying card wheel transmission assembly, and the other is a rolling card wheel transmission assembly.

[0022] In one of the embodiments of the utility model, the card dispenser has a card compartment, a card dispensing channel, and a rolling card wheel. The rear end of the card dispensing channel is an entry opening that communicates with the card compartment, and the front end of the card dispensing channel is exposed at the front end of the card dispenser as a card dispensing opening. The card compartment includes a bottom compartment plate, the card wheel of the rolling card wheel transmission assembly protrudes from the bottom compartment plate, and the card wheel of the flying card wheel transmission assembly is exposed at the front of the bottom compartment plate to be able to dispense paper cards by friction.

[0023] In one of the embodiments of the utility model, the bracket has a protrusion, and the protrusion abuts against the inner ring of the bearing.

[0024] Axial movement can produce some noise. The protrusion of the present application abuts against the inner ring of the bearing, which can limit the axial movement of the bearing and effectively reduce noise.

[0025] In one of the embodiments of the utility model, the convex part is a hollow convex part, and the fixed shaft is fixed on the two supports through a plug screw.

[0026] The plug screw can reliably fix the fixed shaft on the support, preventing noise increase caused by radial transmission of the fixed shaft.

[0027] The utility model discloses the beneficial effects are: the fixed shaft does not rotate, and the card wheel is arranged on the fixed shaft through the bearing sleeve, and the sliding friction (between the wheel and the sleeve) in the prior art is changed into rolling friction, so that the card wheel can almost not make sound when rotating, and the use experience is effectively improved.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0045] The utility model will be described in detail below in combination with various drawings.

[0046] Embodiment 1

[0047] As Figures 1-11 shown, the present embodiment provides a mute card dispenser based on rocker interaction and idler gear drive, including card dispensing box 1, idler gear card dispensing mechanism 2, rotating mechanism 3, lower pressing baffle 4, elastic lower pressing mechanism 5 and rocker interaction control system 6.

[0048] The card dispenser 1 is provided with a card compartment 11 and a card dispensing channel 12. The rear end of the card dispensing channel 12 is a card inlet 121 communicating with the card compartment 11, and the front end of the card dispensing channel 12 is a card dispensing opening 122 exposed at the front end of the card dispenser 1. In this embodiment, the side walls on the left and right sides of the card dispenser 1 corresponding to the card compartment 11 are transparent plates, allowing users to see the card dispensing process from both sides, meeting the psychological needs of users for fairness in card games. The bottom compartment plate of the card compartment 11 is arranged in a front-low and rear-high manner. Since the card rolling wheel 26 needs to protrude from the middle of the bottom compartment plate, it will inevitably cause the card to tilt backward or forward. In the case of backward tilting of the card (i.e., the middle of the card is lifted by the card rolling wheel, and when the card is unbalanced, the rear end of the card is pressed downward, and the front end is lifted upward), the front end of the card is lifted to a certain height, which may cause the front end of the card to rest on the downward stop plate 4. Therefore, the middle of the bottom compartment plate in this embodiment is designed with a concave (downward recessed) design, dividing the bottom compartment plate into a bottom front compartment plate 111 and a bottom rear compartment plate 112. The inclination angle of the bottom front compartment plate 111 with the horizontal plane is smaller than that of the bottom rear compartment plate 112 with the horizontal plane, and the card rolling wheel 26 protrudes upward at the connection between the bottom front compartment plate and the bottom rear compartment plate (or the rear end of the bottom front compartment plate or the front end of the bottom rear compartment plate can protrude upward). Alternatively, the rear part of the upper side of the bottom compartment plate is provided with a plurality of wedge-shaped blocks, which are arranged in a front-low and rear-high manner. The upper surfaces of the plurality of wedge-shaped blocks are on the same inclined plane, which is regarded as the bottom rear compartment plate 112, and the card rolling wheel 26 protrudes upward at the front end of the inclined plane. It should be noted that the concave design has various forms and is not limited to the two specific forms described above. In this embodiment, the orientation of the card dispensing opening 122 is defined as "front". Generally, the inclination angle of the bottom front compartment plate 111 is 4-7°, and the inclination angle of the bottom rear compartment plate 112 is 8-12°. In this way, when the card slides from the rear to the front, the card is arranged in a front-low and rear-high manner, and the horizontal inclination angle of the card gradually decreases (e.g., from 8° to 5°). During the change of the inclination angle of the card, the front end of the card has an upward tilting force, thereby lifting the downward stop plate 4 upward.

[0049] The idler gear dispensing mechanism 2 is arranged in the dispensing box 1, comprising a flying card motor 21, a flying card fixed shaft 22 and a flying card wheel 23 (belonging to a flying card wheel transmission assembly), further comprising a rolling card motor 24, a rolling card fixed shaft 25 and a rolling card wheel 26 (belonging to a rolling card wheel transmission assembly). The flying card motor 21 is arranged in the dispensing box 1, and a flying card gear is arranged on the motor shaft. Each of the left and right sides in the dispensing box 1 is provided with a support 27, and the two ends of the flying card fixed shaft 22 are fixed on the two supports 27 respectively. The flying card fixed shaft 22 is a metal shaft and cannot rotate. A larger through hole is arranged at the axis of the flying card wheel 23, and a bearing (generally two, one at each end, i.e. the outer ring of the bearing is arranged in the through hole) is arranged in the through hole (generally at the position of the two ends of the through hole). The bearing sleeve is arranged on the flying card fixed shaft 22 (i.e. the inner ring of the bearing is sleeved on the fixed shaft), so that almost no sound is generated when the flying card wheel 23 rotates; a circle of teeth is arranged at the middle part of the flying card wheel 23, and the flying card wheel 23 is directly engaged with the flying card gear through the teeth, thereby reducing the transmission stages and providing conditions for reducing the overall size of the card dispenser; the two sides of the teeth of the flying card wheel 23 are prismatic structures, and rubber sleeves are sleeved on the prismatic structures. The rubber sleeves are elastically sleeved on the prismatic structures, so that no adhesive or the like is needed. By arranging the rubber sleeves, the friction with the cards can be effectively increased. The flying card wheel 23 is directly engaged with the flying card gear, so that the flying card motor 21 can directly drive the flying card wheel 23 to rotate, without the need to arrange a special multi-stage transmission system (noise will be generated at multiple positions) as in the prior art, thereby effectively reducing the noise; and the sliding friction (between the wheel and the shaft sleeve) in the prior art is changed to rolling friction, thereby further reducing the noise (in the case of a very good bearing, almost no noise is generated when rotating; since a "one-to-one" transmission mode is adopted (not a motor driving multiple wheels), the rated power of the motor becomes smaller. The use of a small-power motor further reduces the noise. The flying card wheel 23 is exposed at the front of the bottom front warehouse plate (a window is arranged at the front of the bottom front warehouse plate accordingly), so as to send out the cards by friction. The rolling card motor 24, the rolling card fixed shaft 25 and the rolling card wheel 26 have the same structure as the flying card motor 21, the flying card fixed shaft 22 and the flying card wheel 23. The two ends of the rolling card wheel 26 are rotatably sleeved on the rolling card fixed shaft 25 through at least one bearing, the rolling card fixed shaft 25 is fixed on the support in the dispensing box, and a rolling card gear is arranged on the motor shaft of the rolling card motor 24; a circle of teeth is arranged at the middle part of the rolling card wheel, and the rolling card wheel is directly engaged with the rolling card gear through the teeth; the two sides of the teeth of the rolling card wheel are prismatic structures, and rubber sleeves are sleeved on the prismatic structures; the difference is that the rolling card wheel 26 protrudes at the connection between the bottom front warehouse plate 111 and the bottom rear warehouse plate 112. In this embodiment, the teeth of the flying card wheel 23 and the rolling card wheel 26 are at the middle part, and the lengths of the rubber sleeves on the two sides are equal, so that symmetry and balance can be maintained during operation, thereby avoiding noise caused by shaking and vibration due to unbalanced left and right forces.

[0050] In operation, the flying card fixing shaft 22 and the rolling card fixing shaft 25 do not rotate, and the flying card wheel 23 and the rolling card wheel 26 rotate. Since the flying card wheel 23 and the rolling card wheel 26 are rotatably sleeved with the flying card fixing shaft 22 and the rolling card fixing shaft 25 through bearings, noise generated when the flying card wheel 23 and the rolling card wheel 26 rotate is minimal. Meanwhile, the flying card motor 21 and the rolling card motor 24 are directly engaged with the flying card wheel 23 and the rolling card wheel 26, and do not need a multi-stage transmission system, which can further reduce noise and reduce the overall size and weight of the card dispenser.

[0051] The rotating mechanism 3 comprises a rotating base 31, a rotating motor 32 and a gyroscope 33. The rotating base 31 is rotatably arranged at the bottom of the card dispensing box 1. The rotating motor 32 and the gyroscope 33 are arranged in the card dispensing box 1. The rotating motor 32 is connected with the rotating base 31 through a gear transmission. The gyroscope 33 is electrically connected with the processing unit 61. The processing unit 61 controls the operation of the rotating motor 32 based on the number of players and the rotation angle fed back by the gyroscope 33. Compared with the prior art which uses multiple baffles to convert the angle by light signals, the angle measured by the gyroscope 33 is more accurate, so that the card dispenser of the present embodiment is more accurate in angle control. Moreover, the complex design of multiple baffles is cancelled, and the gyroscope 33 arranged at a certain position in the card dispensing box 1 is used instead, which is conducive to reducing the size of the card dispenser.

[0052] The lower pressing baffle 4 is arranged at the front end of the card storage 11 and is above the flying card wheel 23. A gap of 0.3-0.8mm is formed between the lower end of the lower pressing baffle 4 and the wheel rim of the flying card wheel 23, through which the card enters the card dispensing channel. The lower pressing baffle 4 has an elastic pressing force of 0.2-1.2N. When the card enters the gap, the lower pressing baffle 4 is lifted up, so that the card dispenser with this structure can be used for cards of different thicknesses. In this embodiment, the lower end surface of the lower pressing baffle 4 is provided with a notch 41 formed by material removal processing to avoid interference between the flying card wheel 23 and the lower pressing baffle 4. In this embodiment, the lower end rear edge of the lower pressing baffle 4 has a circular arc-shaped guide corner 42 with a radius of 0.5-1.2mm. A limiting plate 14 is arranged at the front side of the card storage 11 to limit the lower pressing limit position of the lower pressing baffle 4 to avoid excessive pressing of the lower pressing baffle 4. The lower pressing baffle 4 is used to press the card entry port 121 of the card dispensing channel 12, so that the card will not slide into the card dispensing channel due to gravity. When the card rolling wheel 26 drives the bottom card to slide forward, the front side edge of the bottom card is pressed against the guide corner 42 of the lower pressing baffle 4. Under the action of the gravity of the card stack, the bottom card slightly contacts the card rolling wheel 26 at the middle part. With the forward pushing of the card rolling wheel 26, the bottom card penetrates into the lower pressing baffle 4 along the guide corner 42 of the lower pressing baffle 4, and the spring 53 increases the pressing force to avoid the sliding of the cards other than the bottom card into the card dispensing channel, which causes the dispensing to be not smooth. The lower pressing baffle 4 presses the card to slightly bend the middle part of the bottom card downward, and the second last card (and the cards above it are prevented from contacting the card rolling wheel and being driven by the guide corner of the lower pressing baffle 4) does not enter the card dispensing channel, so that only the bottom card enters the card dispensing channel 12 to realize single flying card dispensing.

[0053] The elastic pressing mechanism 5 is arranged between the side of the pressing baffle 4 and the side wall of the card compartment 11, and is used to make the pressing baffle 4 have an adjustable elastic pressing force of 0.2-1.2 N; the elastic pressing mechanism 5 is provided with two, and the two elastic pressing mechanisms 5 are symmetrically arranged on the left and right sides of the card inlet 121. The elastic pressing mechanism 5 can have various forms as long as the above functions are met. Optionally, the elastic pressing mechanism 5 comprises a sliding block 51, an adjusting top screw 52 and a spring 53; the side wall of the card compartment 11 (which belongs to a part of the entity of the card dispensing box 1) is provided with a vertical sliding groove 13, and the sliding groove 13 is in communication with the card compartment 11, and the two sliding grooves 13 are symmetrically arranged on the left and right sides of the card inlet 121; the sliding block 51 is fixed (can be integrally formed) to the side of the pressing baffle 4 and is slidingly arranged in the sliding groove 13; the upper section of the sliding groove 13 is provided with an internal thread (the cross section of the sliding groove 13 is not necessarily circular, so the internal thread can be a circumferential discontinuous thread); the adjusting top screw 52 is screwed into the upper section of the sliding groove 13; and the spring 53 is arranged in the sliding groove 13 and has two ends respectively abutting against the sliding block 51 and the adjusting top screw 52. By adjusting the adjusting top screw 52 in the forward or reverse direction, the elastic force acting on the pressing baffle 4 can be adjusted, so that the pressing force of the pressing baffle 4 can be adjusted.

[0054] The rocker interactive control system 6 is arranged on the card dispensing box 1 and comprises a processing unit 61, a rocker control unit 62, a display unit 63 and a confirmation unit 64 which are electrically connected with the processing unit 61. The processing unit 61 is pre-stored with small programs (such as paper card game small programs which can be selected in the card dispensing mode, such as fan-tan, domino, double-knuckle, and so on); the card dispensing mode, the number of card dispensing people, the number of card dispensing, the number of bottom cards, the dispensing direction and the increase or decrease of the number of card dispensing people, the number of card dispensing and the number of bottom cards are selected (set, modified) through the rocker control unit 62, wherein when the dispensing direction is selected, the rocker needs to be pushed for a long time (such as 1-2 s; in this embodiment, after the rocker is pushed for a long time, the processing unit 61 displays a progress bar through the display unit 63, and after the progress bar is completed, the direction setting is completed; when the rocker is vertically arranged, the direction in which the rocker is pushed is the dispensing direction, so no further description is needed; when the rocker is inclined or nearly horizontally arranged, the direction in which the rocker is pushed downward is “front” when the dispensing direction is set); the rest of the rocker can be pushed for a short time (such as 0.1-0.5 s); the processing unit 61 displays the related content (referring to the selection of the card dispensing mode, the number of card dispensing people, the number of card dispensing and the number of bottom cards) selected or set by the rocker control unit 62 through the display unit 63; the confirmation unit 64 is used to confirm the related operation of the rocker control unit or return to the last menu; and the processing unit 61 controls the operation of the lazy tooth wheel dispensing mechanism 2 and the rotating mechanism 3 based on the card dispensing mode, the number of card dispensing people, the number of card dispensing, the number of bottom cards and the dispensing direction, thereby dispensing cards for the user.

[0055] The rocker interactive control system 6 is used to set the dealing mode, the number of dealers, the number of cards, the number of bottom cards and the dealing direction, compared with the common information input mode such as button knob, the operation steps and time are reduced, the operation is more intuitive, and the operation complexity is reduced; in addition, the rocker is a game machine module, and the design is consistent with the entertainment of cards.

[0056] The photoelectric signal sensor 65 is arranged in the dealing channel 12, the photoelectric signal sensor 65 is electrically connected with the processing unit 61, the processing unit 61 controls the working of the lazy gear dealing mechanism 2 and the rotating mechanism 3 based on the electric signal of the photoelectric signal sensor 65, and a real-time closed-loop control mechanism is formed.

[0057] As shown in Figure 12 , the dealing process is as follows:

[0058] Step S1, the flying card motor 21 rotates. The flying card motor 21 starts to rotate 100 ms in advance, ensures that the required dealing distance corresponding to the rotating speed is reached before the first card is issued and keeps constant speed, so as to ensure the flying card distance. In fact, the flying card motor 21 can reach constant speed in a very short time after starting.

[0059] Step S2, dealing. The card rolling motor 24 starts to rotate; the card passes through the dealing channel 12 under the action of the flying card motor 21 and the card rolling motor 24, and shields the photoelectric signal sensor 65; as the card flies out of the dealing opening 122, the photoelectric signal sensor 65 is turned on, and the card rolling motor 24 stops rotating. From the start of the card rolling motor 24 to the stop of the card rolling motor 24, it is generally about 30 ms.

[0060] Step S3, rotation. The rotating motor 32 starts to rotate; the gyroscope 33 feeds back the rotating angle in real time; when the rotating angle reaches the designed angle, the rotating motor 32 stops rotating. In order to give the rotating flow sufficient time, the card rolling motor 24 generally stops rotating for about 500 ms.

[0061] Step S4, repeatedly execute the above steps S2 and S3.

[0062] Step S5, stop dealing. After the last card is issued (the cards are all dealt), the flying card motor 21 stops rotating, and the card rolling motor 24 and the rotating motor 32 will not start again. If there is no electric signal of the photoelectric signal sensor 65 in three dealing periods, it means that the cards are all dealt.

[0063] In the step S2, if the photoelectric signal sensor 65 is still turned on after the card rolling motor 24 rotates for 1 s, it proves that there is no card in the card discharge 11 or there is a card jam problem, and the card warehouse needs to be checked and the fault needs to be eliminated.

[0064] If there is a card in the card channel when the card is dealt (after the previous card is dealt, the next card may be partially brought out, causing the photoelectric signal sensor 65 to be blocked; in this embodiment, because the lower pressing plate has elastic pressing force, such phenomenon is very rare), the flying card motor 21 and the rolling card motor 24 are reversed until the photoelectric signal sensor 65 is turned on (i.e. the part brought out returns to the card compartment 11), and then the flying card motor 21 and the rolling card motor 24 stop rotating; then steps S1, S2, S3, S4 and S5 are performed.

[0065] Embodiment 2

[0066] As shown in the drawings, the difference between this embodiment and embodiment 1 is that the support 27 has a convex part 271 abutting against the inner ring 81 of the bearing 8. Axial movement will cause a certain sound, and the convex part 271 abutting against the inner ring 81 of the bearing 8 can limit the axial movement of the bearing 8, effectively reducing the noise. Figure 13 As shown in the drawings, in this embodiment, the convex part 271 is a hollow convex part 271.

[0067] Figure 13 As shown in the drawings, in this embodiment, the convex part 271 is a hollow convex part 271.

[0068] In this embodiment, the fixed shaft is fixed on the two supports by a jam screw. The jam screw can reliably fix the fixed shaft on the support, preventing the increase of noise caused by the radial transmission of the fixed shaft. As shown in the drawings, the jam screw includes a rod 71 and a locking bolt 72, one end of the rod 71 has a anti-loose cap (not shown in the drawings), and one end has a threaded hole, and the locking bolt 72 passes through the support 27 and is fixed with the threaded hole of the rod 71, so as to firmly fix the fixed shaft on the support 27. Figure 13

[0069] The above is only the preferred embodiment of the present application, and is not limited to the patent protection range of the present application, and any equivalent structural transformation, direct or indirect application in other related technical fields, is also included in the protection range of the present application.​​
