Description

Technical Field

[0001] The invention belongs to the technical field of entertainment products, and in particular relates to a card dealing driving gear box device 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 methods. After the cards are thoroughly shuffled and evenly dealt according to specific rules, they are time-consuming and require 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 gaming 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; for another example, the Chinese invention patent with the authorization announcement number "CN105854278B" introduces a poker machine and its card dealing device and card dealing mechanism, the card dealing mechanism includes a card dealing pressure plate installed on a card dealing bracket outside the card outlet of the flip box, one end of the card dealing pressure plate is hinged with the card dealing bracket, the other end of the card dealing pressure plate is installed with a card pressing piece, a card dealing roller arranged corresponding to the card pressing piece up and down, the card dealing pressure plate gives the card pressing piece a tendency to approach the card dealing roller through an elastic mechanism; the card dealing roller and the card pressing piece are arranged corresponding to each other up and down and a gap is left between the two for the passage of playing cards, the card dealing roller is provided with a plurality of annular grooves or annular protrusions, the card pressing piece is provided with corresponding protrusions or grooves, the card pressing piece does not rotate synchronously with the card dealing roller, and the flip seat or the card dealing bracket is provided with a card pressing limit mechanism for limiting the activity range of the card pressing piece; although both can achieve efficient card location and card dealing work, there is still a problem of numerous components. In addition, the card dealing drive structure is one of the most important components of the card dealing machine. The rollers that are closer are connected by gear meshing, while those that are farther apart are connected by pulleys. Some of the connections are at one end of the roller, and some are at the other end of the roller, resulting in a very scattered and unstable transmission position. During repair and daily maintenance, the card dealing machine needs to be constantly turned to observe the transmission connection relationship between the rollers, which is very troublesome to operate.
