Description

Technical Field

[0001] This utility model belongs to the field of entertainment products technology, specifically relating to a rotary detection gearbox structure for a card dealing machine. Background Technology

[0002] Playing cards, as one of the most common forms of entertainment in people's lives, are loved by a wide range of people of all ages due to their diverse gameplay and suitability for all ages. Traditional playing cards involve manual shuffling and dealing, thoroughly shuffling the cards before dealing them according to specific game rules. This process is time-consuming, requires skill, and is susceptible to cheating, making it difficult to guarantee fairness. With the development of technology, various machines that replace manual shuffling and dealing have emerged, significantly improving the card game experience. Existing card dealing machines, through mechanical structures and electric drive systems, can quickly and accurately distribute playing cards to players or participants. Automatic card dealing machines typically include a housing that stores playing cards, a card delivery mechanism, a card dealing mechanism, and a control system. The card delivery mechanism delivers single playing cards to the card dealing mechanism, which then uses rotation, pushing, or other methods to pass the cards through the dealing slot in the housing and deliver them to the dealing position, allowing players to easily retrieve them. This eliminates the tediousness of manual dealing, saving time and effort and providing a better gaming experience.

[0003] Publicly available patent documents contain relevant technical information about automatic card dealing machines, including CN101972544B (a card dealing machine), CN201912755U (a card dealing mechanism for a card dealing machine), CN205216160U (a card-splitting device for a poker card dealing machine), CN118304637A (a card dealing machine), and CN102029060A (a card dealing mechanism and its flipping clamp device for an automatic card shuffling machine), etc. However, existing card dealing machines generally suffer from complex structures and numerous components, resulting in high assembly and production costs, poor operational stability, and difficulty in ensuring the accuracy and smoothness of card dealing. They also suffer from cumbersome debugging, inconvenience, and high costs. A typical example is the "card dealing machine" described in patent announcement number CN215691569U, which includes a base and a card dealing mechanism. The base has a horizontal rotating mechanism, and the card dealing mechanism is connected to the horizontal rotating mechanism. The card dealing mechanism includes a rotating base, a first dealing roller, a second dealing roller, and a drive unit. The rotating base has a card storage compartment with a card outlet on one side. The first dealing roller is installed in the storage compartment, and the second dealing roller is installed at the outlet. The second dealing roller has a front roller. The outlet also has two arc-shaped stop plates corresponding to the front rollers, arranged in groups of two. The drive unit is connected to both the first and second dealing rollers. While this mechanism has advantages such as reducing card deformation during dealing, improving card lifespan, and increasing dealing smoothness, its internal structure is complex, and it cannot effectively detect the card dealing and rotation angles. For card dealing machines, rotation and detection of rotation angle are particularly important. Current card dealing machines often use a structure in which a motor drives a gear to rotate around the base directly through a small gearbox, or a structure in which a motor rotates around the base through a worm gearbox. The purpose of both is to reduce the motor speed to adapt to the rotation speed of the card dealing machine. However, the cost of small gearboxes and worm gearboxes is relatively high, and there are situations where they can only be replaced and not repaired. On the other hand, the structure for detecting rotation angle uses a photoelectric sensor to directly detect the rotation position of the base. The aforementioned rotation structure and the structure for detecting rotation angle are usually two independent mechanisms, with parts that are very scattered and have poor precision in their coordination.

[0004] In view of the above, it is necessary to design a rotary detection gearbox structure for a card dealing machine that is simple in structure, highly stable, and low in cost, and that can combine a rotary drive structure with a rotation angle detection structure. To this end, the applicant has made a beneficial design, and the technical solution described below arose from this background. Utility Model Content

[0036] Please continue reading Figures 1 to 5The working principle of the technical solution provided by this utility model is briefly described as follows: When the automatic rotating card dealer needs to be used for automatic card dealing, the user can first put the playing cards into the feeding platform plate 51 of the housing clearance cavity 13. At this time, the feeding power mechanism 52 of the feeding unit 5 causes the feeding platform plate 51 to move, so that the topmost playing card on the pile of playing cards on the feeding platform plate 51 abuts against the card-delivery rubber roller 6. Then, the user can press the aforementioned control button 95 to control and adjust the card dealing logic of the aforementioned card dealer according to the game and needs. The upper PCB control board 94 sends a sensing signal to the PCB main board 91. The PCB main board 91 then sends control commands to the aforementioned rotary motor 41 and card-dealing drive motor 81. The rotary motor 41 operates according to the signal commands. The rotary motor output shaft 411 of the rotary motor 41 further drives the rotary gear assembly 42. The four-stage rotary reduction gear 424 rotates around the base positioning gear 32 on the base 3, causing the rotary motor 41 and the main frame 2 to rotate together around the base 3. Through the rotary motor 41, the main frame can be accurately and reliably controlled. 2. The rotation of housing 1 is stable and can be stopped at a preset position. Then, the aforementioned card-dealing drive motor 81 drives the transmission gear assembly 82 to operate. The playing cards that are in contact with the card-feeding roller 6 move towards the card inlet 222 and pass through the card inlet 222 under the rotational friction of the card-feeding roller 6. Then, the card-dispensing roller 72 rotates to dispense the playing cards from the aforementioned card outlet 12. When the aforementioned card-dispensing light sensor 92 detects a card, it sends information to the PCB motherboard 91. The aforementioned rotation light sensor 93 can effectively detect and identify the rotation light sensor gear 4234. The rotation state detects the rotation angle of the main frame 2 and the housing 1 and sends a signal to the PCB motherboard 91. After receiving the sensing signal, the PCB motherboard 91 issues a control command to drive the main frame 2 and the housing 1 to rotate horizontally again. Finally, when the main frame 2 and the housing 1 rotate to the predetermined position, the PCB motherboard 91 issues a control command to the rotary motor 41 and the card dealing drive motor 81 again, so that the playing cards loaded into the card inlet 222 pass between the upper card dealing pre-roller 71 and the lower card dealing pre-roller 72 and are dealt to the player.
