Description

Technical Field

[0001] This utility model relates to the field of entertainment equipment technology, and in particular to an inductive rotating card dealing machine. Background Technology

[0002] A card dealing machine is a device that automatically deals playing cards or similar cards. It typically includes a main body, a base, a rotating mechanism that drives their relative rotation, and a sensing mechanism for positioning the dealing location. To improve dealing accuracy, some existing technologies incorporate an elastic buffer component between the rotating mechanism and the base to cushion the impact generated during startup or sudden stop.

[0003] As shown in Chinese utility model patent "CN222693970U", this invention uses a positioning gear that meshes with a rotating gear disk of a rotating mechanism within a base, and a rotation sensing component on the positioning gear to detect its rotational state. However, during equipment startup or emergency stop, the rotating mechanism often experiences non-targeted micro-rotations due to inertia, and the positioning gear linked to the rotating mechanism also rotates accordingly. At this time, the sensing mechanism continues to perform sensing operations, leading to misjudgments and vibrations, affecting the accuracy and stability of card dealing.

[0004] Therefore, a sensor-based rotating card dealer with high sensing accuracy and stability needs to be designed. Utility Model Content

[0028] The end of the induction disk facing the induction gear is provided with one of the plurality of recessed grooves or the plurality of engaging posts;

[0029] The engagement post is inserted into the relief groove and abuts against the end of the relief groove during normal operation to engage with the sensing gear, and forms an active gap with the relief groove during the start-up or emergency stop phase.

[0030] Optionally, the sensing gear meshes with the central gear disk or the planetary gear.

[0031] Optionally, the ratio of the number of teeth of the central gear to the number of the sensing gear multiplied by the number of sensing triggers is equal to 60.

[0041] Compared with the prior art, the advantages of this application are:

During startup or emergency stop, it automatically disengages from the rotating mechanism, preventing false sensing of minor, non-targeted rotations caused by inertia, and avoiding vibration of the sensing mechanism. This effectively avoids misjudgments, improving sensing accuracy, card dealing accuracy, and equipment stability. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

In addition, the terms "first" and "second" are only used to distinguish multiple parts or structures with the same or similar structures, and do not indicate any special limitation on the arrangement order or connection relationship.

[0069] Example 1

[0070] Please refer to Figures 1 to 9 This utility model provides an inductive rotating card dealer 100, which includes: a card dealer body 1, a base 2, a rotating mechanism 3, an elastic buffer component, and an inductive mechanism 5.

[0071] The card dealing machine body 1 typically includes a card storage compartment a, a card inlet b and a card dealing outlet c connecting the card storage compartment a, a card delivery component 11 that pushes cards from the card storage compartment a to the card dealing outlet c, a card dealing component 12 that dispenses cards from the card dealing outlet c, and a control panel 13 and a control circuit board 14 that control the operation of the card dealing machine body 1. The card delivery component 11 and the card dealing component 12 can be referenced from existing technologies, and therefore will not be elaborated upon here.

[0072] The base 2 is located at the bottom of the card dealing machine body 1 and is used to support the card dealing machine body 1.

[0073] The rotating mechanism 3 is located between the base 2 and the card dealing machine body 1, and is used to drive the card dealing machine body 1 to rotate. Its main function is to drive the card dealing machine body 1 to rotate relative to the base 2 around a set axis, so as to sequentially deal cards to multiple target locations. Optionally, please refer to... Figures 2 to 5 In this embodiment, the rotating mechanism 3 includes: a central gear 31, a drive motor 32, a planetary gear 34, and a control circuit board 14.

[0074] A central gear 31 is mounted inside the base 2, and its upper end is rotatably connected to the bottom of the card dealing machine body 1. A drive motor 32 is mounted inside the card dealing machine body 1. A planetary gear 34 is rotatably mounted inside the card dealing machine body 1, and is driven by the drive motor 32 and meshes with the central gear 31. Optionally, the output shaft of the drive motor 32 is driven by the planetary gear 34 through a reduction gear set 33. A control circuit board 14 is located inside the card dealing machine body 1 and is electrically connected to the drive motor 32 for controlling the rotation of the drive motor 32. Thus, the drive motor 32 drives the planetary gear 34 to rotate, and the planetary gear 34 rotates around the central gear 31, thereby causing the card dealing machine body 1 to rotate relative to the base 2 around a set axis. Of course, in other embodiments, the rotating mechanism 3 may also be implemented using a structure such as the motor + driving wheel + driven wheel + synchronous belt as in the authorization announcement number "CN219208951U", or other structures, as long as it can drive the card dealing machine body 1 to rotate relative to the base 2 around the set axis. No specific restrictions are made here.

[0075] The sensing mechanism 5 and the rotating mechanism 3 can be selectively engaged. The sensing mechanism 5 engages with the rotating mechanism 3 during normal operation to sense its rotational state; during start-up or emergency stop phases, it disengages from the rotating mechanism 3 to avoid false sensing and vibration of the sensing mechanism 5. Understandably, during engagement, some components of the sensing mechanism 5 can move synchronously with some components of the rotating mechanism 3; when disengaged, the rotating mechanism 3 does not act on some components of the sensing mechanism 5, and the two no longer move synchronously, thus the sensing mechanism 5 remains relatively stationary. Furthermore, normal operation of the rotating mechanism 3 refers to the process during which the rotating mechanism 3 drives the card dealing machine body 1 to rotate, excluding start-up and emergency stop phases.

[0076] Because the sensing mechanism 5 of the inductive rotary card dealer 100 adopts a selective engagement structure design, the sensing mechanism 5 only engages with the rotary mechanism 3 and senses its rotational state when the rotary mechanism 3 is operating normally; during equipment start-up or emergency stop, it automatically disengages from the rotary mechanism 3, avoiding false sensing of non-targeted minute rotations caused by inertia, and also preventing vibration of the sensing mechanism 5. This effectively avoids misjudgments, improves sensing accuracy, card dealing accuracy, and equipment stability. To achieve the selective engagement design of the sensing mechanism 5 and the rotary mechanism 3, optionally, please refer to... Figure 4 and Figures 6 to 8 In this embodiment, the sensing mechanism 5 includes a sensing disk 61, a sensing trigger 51, and a sensing receiver 52.

[0077] The induction plate 61 is rotatably disposed inside the bottom shell 17 of the card dealing machine body 1. When the rotating mechanism 3 is working normally, the induction plate 61 engages with the rotating mechanism 3. During the start-up or emergency stop phase, it forms an active gap with the rotating mechanism 3 to avoid the induction plate 61 from shaking.

[0078] Six induction triggers 51 are provided on the induction disk 61; induction receivers 52 are located inside the bottom shell 17 and cooperate with the induction triggers 51. Of course, in other embodiments, the number of induction triggers 51 may be one, two, three, four, five, seven or more, which needs to be set as needed in combination with the size of the induction disk 61 and the induction accuracy required by the induction rotating card dealer 100, and no specific limitation is made here.

[0079] Alternatively, please refer to Figures 6 to 8 In this embodiment, the inductive rotary card dealer 100 further includes an inductive gear 62, recessed grooves e, and engaging posts 611. The inductive gear 62 is coaxially rotatably disposed with the inductive disk 61 and is linked to the rotating mechanism 3. Specifically, the inductive gear 62 meshes with the central gear disk 31. Of course, in some other embodiments, the inductive gear 62 may also mesh with the planetary gear 34, or be driven by the central gear disk 31 through an intermediate gear (not shown in the figure), without specific limitations. The inductive gear 62 is rotatably disposed within the bottom shell 17 of the card dealer body 1, and four recessed grooves e are circumferentially disposed on its upper end. It can be understood that the four recessed grooves e are arranged in a circumferential array around the inductive gear 62. Optionally, the recessed grooves e are arc-shaped grooves. The end of the inductive disk 61 facing the inductive gear 62 is provided with four engaging posts 611 that insert into the recessed grooves e, abut against the ends of the recessed grooves e to engage with the inductive gear 62 during normal operation, and form an active gap with the recessed grooves e during the start-up or emergency stop phase. Thus, during the startup phase of the rotating mechanism 3, the engaging column 611 is located only within the retraction groove e but does not abut against the end of the retraction groove e, and is in a disengaged state, unable to push the sensing disk 61 to rotate together. During the normal operation phase of the rotating mechanism 3, the engaging column 611 moves to abut against the end of the retraction groove e, and is in an engaged state, pushing the sensing disk 61 to rotate together. During the emergency stop phase of the rotating mechanism 3, the engaging column 611 moves in the opposite direction and separates from the end of the retraction groove e, and is also in a disengaged state, unable to push the sensing disk 61 to rotate together. Of course, in some other embodiments, the retraction groove e can also be circumferentially arranged at the lower end of the sensing gear 62, and its number is not limited to four; it can be one, two, three, or more, and no specific limitation is made here. In this embodiment, six sensing triggers 51 are arranged on the sensing disk 61. Of course, in some other embodiments, a plurality of the engaging columns 611 are circumferentially arranged at one end of the sensing gear 62 facing the sensing disk 61; and a plurality of the retraction grooves e are correspondingly arranged at the end of the sensing disk 61 facing the sensing gear 62.

[0080] Specifically, six sensing triggers 51 are arranged in a circumferential array on the upper surface of the sensing disk 61. Of course, in some other embodiments, the sensing triggers 51 may also be arranged on the lower surface of the sensing disk 61.

[0081] In this way, when the rotating mechanism 3 is working, the sensing trigger 51 located on the sensing disk 61 can be sensed by the sensing trigger 51, thereby sensing the movement state of the sensing gear 62, and thus accurately positioning the card dealing position of the card dealing machine body 1. Of course, in some other embodiments, the selective engagement of the sensing mechanism 5 and the rotating mechanism 3 can also be achieved by a clutch, and no specific limitation is made here.

[0082] Optionally, in some embodiments of this invention, the ratio of the number of teeth of the central gear 31 to the number of teeth of the sensing gear 62 multiplied by the number of sensing triggers 51 equals 60. This allows for precise subdivision into 60 sensing units even when the central gear 31 rotates one full revolution relative to the sensor, thereby improving the ability to distinguish changes in rotation angle. This facilitates relatively even distribution when performing card-sorting operations at 2 to 12 positions.

[0083] Optionally, in this embodiment, the sensing trigger 51 is a six-circular array of sensing plates arranged on the side of the sensing disk 61 facing away from the sensing gear 62, and the sensing receiver 52 is a photoelectric sensor. Of course, the number of sensing plates is not limited to six; it can be one, two, three, four, five, seven, or more. In other embodiments, the sensing trigger 51 can also be a contact spring, and the sensing receiver 52 can be a corresponding contact sensor; or the sensing trigger 51 and the sensing receiver 52 can be Hall effect sensors. No specific limitations are imposed here.

[0084] Alternatively, please refer to Figure 4 In this embodiment, the bottom shell 17 of the card dealing machine body 1 is provided with a downwardly protruding planetary gear assembly seat 171 and a sensor gear assembly seat 172 with notches. The planetary gear assembly seat 171 and the sensor gear assembly seat 172 are respectively disposed on opposite sides of the central gear disk 31, making the internal structure layout more compact and reasonable. The planetary gear 34 is rotatably disposed in the planetary gear assembly seat 171 and partially passes through its notch to mesh with the central gear disk 31; the sensor gear 62 is rotatably disposed in the sensor gear assembly seat 172 and partially passes through its notch to mesh with the central gear disk 31. In this way, both the planetary gear 34 and the sensor gear 62 are embedded in the bottom shell 17, which helps to resist external impacts or dust contamination.

[0085] To cushion the mechanical impact from the interior of the rotating mechanism 3 and / or the base 2 during startup or emergency stop, optionally, please refer to Figure 3 , Figure 4 and Figure 9 In this embodiment, the inductive rotating card dealer 100 also includes an elastic buffer assembly disposed between the rotating mechanism 3 and the base 2 for buffering the impact of starting or stopping. That is, the elastic buffer assembly can absorb or buffer the mechanical impact force caused by instantaneous starting or stopping, thereby effectively reducing the vibration and wear inside the rotating mechanism 3 and / or between the rotating mechanism 3 and the base 2.

[0086] Optionally, the elastic buffer assembly includes: arc-shaped positioning holes o4, limiting posts 41, arc-shaped buffer grooves d, buffer springs 42, and positioning posts 43. Three arc-shaped positioning holes o4 are arranged in a circumferential array along the center of the central gear disk 31 on the base 2. Three limiting posts 41 are correspondingly located on the bottom surface of the central gear disk 31 to engage with the arc-shaped positioning holes o4. Three arc-shaped buffer grooves d are arranged in a circumferential array along the bottom surface of the central gear disk 31, and two buffer springs 42 are disposed within each arc-shaped buffer groove d. Three positioning posts 43 are correspondingly located within the base 2, each positioning post 43 being inserted into one arc-shaped buffer groove d and positioned between two buffer springs 42. Thus, upon startup, the drive motor 32 rotates, driving the planetary gear 34 to rotate. The planetary gear 34 then pushes the central gear disk 31 to rotate until the limiting post 41 of the central gear disk 31 stops when it hits the end of the arc-shaped positioning hole o4 in the base 2. During this process, the positioning post 43 in the base 2 compresses the buffer spring 42 in the arc-shaped buffer groove d of the central gear disk 31 to buffer rigid impact. After the planetary gear 34 stops, its rotation drives the card dealing machine body 1 to rotate around the base 2. The principle of the emergency stop process is similar and will not be elaborated further here. Of course, in other embodiments, the number of arc-shaped positioning holes o4, limiting posts 41, and arc-shaped buffer grooves d can be one, two, four, or more, and no specific limitation is made here.

[0087] To position the center gear 31 on the base 2, optionally, please refer to... Figure 3 and Figure 4 In this embodiment, the limiting post 41 has a first screw hole o1, and the central gear plate 31 is assembled on the base 2 through the limiting post 41, the first screw 71 that cooperates with the first screw hole o1, and the arc-shaped positioning hole o4.

[0088] To facilitate quick assembly and disassembly of the base 2 and the central gear plate 31 from the card dealing machine body 1, optionally, please refer to... Figure 4 In this embodiment, the bottom of the card dealing machine body 1 is provided with a downwardly extending rotating shaft 18 having a second screw hole o2. The base 2 has a through hole o3 corresponding to the rotating shaft 18. The central gear plate 31 is rotatably mounted on the rotating shaft 18 via a bearing 8; the bearing 8 is limited and fixed by a second screw 72 that mates with the second screw hole o2. Thus, the base 2, with the central gear plate 31 and bearing 8 fixed, can be fixed to the rotating shaft 18 of the card dealing machine body 1 using only one second screw 72, achieving quick assembly and disassembly.

[0089] Alternatively, please refer to Figures 1 to 3In this embodiment, the card dealing machine body 1 is also equipped with a power supply, which powers the card dealing component 12, the card feeding component 11, the control circuit board 14, the rotating mechanism 3, and the sensing mechanism 5. Furthermore, the power supply is a rechargeable battery 15, and the card dealing machine body 1 is also equipped with a charging interface 16 for charging the rechargeable battery 15.

[0090] Example 2

[0091] Please refer to Figures 10 to 13 This embodiment is basically the same as Embodiment 1, except that there is no sensing gear 62. When the rotating mechanism 3 is working normally, the sensing disk 61 directly engages with the planetary gear 34, and during the start-up or emergency stop phases, it forms an active gap with the planetary gear 34. Optionally, the sensing disk 61 is coaxially disposed above the planetary gear 34, and four engaging posts 611 are provided on the upper end of the planetary gear 34. The end of the sensing disk 61 facing the planetary gear 34 has four recessed grooves e. The engaging posts 611 are inserted into the recessed grooves e and abut against the end of the recessed grooves e during normal operation to engage with the sensing gear 62, forming an active gap with the recessed grooves e during the start-up or emergency stop phases. Of course, in other embodiments, the number of recessed grooves e and engaging posts 611 can be one, two, three, five, or more, and no specific limitation is made here. This also allows for a selective connection design between the sensing mechanism 5 and the rotating mechanism 3. Of course, in other embodiments, the engagement post 611 may also be provided at the end of the induction disk 61 facing the planetary gear 34, and the relief groove e may be provided at the end of the planetary gear 34 facing the induction disk 61. No specific limitation is made here.

[0092] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the substance of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
