Description

Technical Field

[0001] The invention belongs to the technical field of entertainment products, and in particular relates to a rotation detection gear box structure for a card dealing machine. Background Art

[0002] As the most common entertainment item in people's lives, playing cards are deeply loved by the general public because of their diverse playing methods and suitability for all ages. Traditional poker games use manual shuffling and manual dealing. After the cards are thoroughly shuffled and evenly dealt according to specific game rules, it takes time and requires skills. There is also the possibility of cheating, and it is difficult to ensure the fairness of the game. With the development of science and technology, various machines that replace manual shuffling and dealing have been introduced one after another, greatly improving the experience of poker games. The existing card dealing machine can quickly and accurately distribute playing cards to players or participants through a mechanical structure and an electric drive system. The automatic card dealing machine usually includes a cover that can store playing cards, a card delivery mechanism, a card dealing mechanism, and a control system. The card delivery mechanism delivers a single playing card to the card dealing mechanism. The card dealing mechanism passes the playing card through the card dealing port on the cover by rotating, pushing or other means and delivers it to the card dealing position so that the player can easily take it, thereby eliminating the tediousness of manual card dealing, saving time and effort, and providing a better game experience.

[0003] In the public patent documents, relevant technical information about automatic card dealing machines can be found, such as 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), CN102029060A (a card dealing mechanism for an automatic shuffler and a card flipping clamp device thereof), etc. However, the existing card dealing machine structure generally has the problem of complex structure and a large number of components, which not only causes high assembly and production costs, but also has poor operating stability, and the accuracy and smoothness of the working card dealing cannot be effectively guaranteed, and there are the disadvantages of cumbersome and inconvenient debugging and high cost. A typical example is "a card dealing machine" introduced in the authorization announcement number CN215691569U, which includes a base and a card dealing mechanism. The base is provided with a horizontal rotating mechanism, and the card dealing mechanism is connected to the horizontal rotating mechanism. The card-dealing mechanism includes a rotating body base, a first card-dealing roller, a second card-dealing roller and a driving device. The rotating body base is provided with a card storage bin, one side of the card storage bin is provided with a card outlet, the first card-dealing roller is installed in the card storage bin, the second card-dealing roller is installed at the card outlet, and the second card-dealing roller is provided with a front roller. The card outlet also has an arc-shaped stopper plate arranged in a group of two corresponding to the front roller, and the driving device is connected to the first card-dealing roller and the second card-dealing roller in a transmission manner. Although it has the advantages of being able to reduce the deformation of playing cards during the card-dealing process, and improving the service life of playing cards and the smoothness of card-dealing, the internal structure of this card-dealing machine is complicated, and there is a problem that the card-dealing and rotation angles cannot be effectively detected. For a card dealing machine, rotation and detecting the rotation angle are particularly important. Current card dealing machines often use a structure in which a motor directly drives the gears to rotate around the base through a small gear box, or a structure in which a motor rotates around the base through a worm gear box. The purpose is to reduce the speed of the motor to adapt to the rotation speed of the card dealing machine. However, the cost of small gear boxes and worm gear boxes is relatively high, and there is a situation where they can only be replaced but not repaired. The detection of the rotation angle uses a photoelectric sensor to directly detect the rotation position of the base. The aforementioned rotation structure and the structure for detecting the rotation angle are usually two independent mechanisms, the parts assembly is very scattered and the accuracy of mutual coordination is poor.

[0004] In view of the above situation, it is necessary to design a rotation detection gearbox structure for a card dealing machine that is simple in structure, strong in stability, and low in cost, and that can combine a rotation drive structure with a rotation angle detection structure.
