Description
Technical Field
The invention belongs to the technical field of entertainment products, and particularly relates to a rotation detection gear box structure for a card dealing machine.
Background
Playing cards are popular entertainment products in life, and are popular with people because of various playing methods and suitability for people of all ages. The traditional playing card game adopts the modes of manual shuffling and manual dealing, and the cards are dealt according to specific game rules after being thoroughly and evenly shuffled, so that time and skill are spent, cheating possibility exists, and fairness of the game is difficult to ensure. With the development of science and technology, various machines for replacing manual shuffling and dealing are developed in succession, so that the experience of the poker game is greatly improved. Existing card dealing machines are capable of rapidly and accurately dealing playing cards to players or participants through mechanical structures and electric drive systems, and automatic card dealing machines generally include a housing capable of storing playing cards, a card delivery mechanism and a card delivery mechanism, and a control system, wherein the card delivery mechanism delivers individual playing cards to the card delivery mechanism, and the card delivery mechanism rotates, pushes or otherwise moves the playing cards through a card delivery opening in the housing and delivers the playing cards to a card delivery position, so that players can easily take the playing cards, thereby eliminating the complexity of manual card delivery, saving time and effort, and providing a better game experience.
Related art information about automatic card shoes are found in the open patent literature, and are exemplified by CN101972544B (a card shoe), CN201912755U (a card shoe dealing mechanism for a card shoe), CN205216160U (a card dispensing device for a card shoe), CN118304637a (a card shoe) CN102029060a (a card shoe mechanism for an automatic card shoe and a card turning device thereof), and the like. However, the existing dealing machine structure is generally complex in structure and has the problems of a large number of components, so that not only is assembly and production cost high, but also the operation stability of the dealing machine is poor, the accuracy and smoothness of dealing can not be effectively guaranteed, and the defects of complicated debugging, inconvenience and high manufacturing cost exist. A typical "a card shoe" as described in grant bulletin number CN215691569U includes a base and a card-dealing mechanism. The base is provided with a horizontal rotating mechanism, and the dealing mechanism is connected with the horizontal rotating mechanism. The dealing mechanism comprises a rotator base, a first dealing roller, a second dealing roller and a driving device. The rotary 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 arranged in the card storage bin, the second card dealing roller is arranged at the card outlet, and the second card dealing roller is provided with a front roller. The card outlet is also provided with two arc-shaped stop plates which are arranged in a group and correspond to the front roller, the driving device is in transmission connection with the first card distributing roller and the second card distributing roller, and the card outlet has the advantages of reducing the deformation of the playing cards and improving the service life and smoothness of the playing cards in the card distributing process, however, the internal structure of the card distributor is complex, and the card distributing and rotating angle cannot be effectively detected. The rotation and detection of the rotation angle are particularly important for the card dealing machine, the current card dealing machine usually adopts a structure that a motor directly drives a gear to rotate around a base through a small gear box, or adopts a structure that the motor rotates around the base through a worm gear box, the purpose is to reduce the rotation speed of the motor so as to adapt to the rotation speed of the card dealing machine, but the cost of the small gear box and the worm gear box is relatively high, the situation that the card dealing machine can only be replaced but can not be maintained exists, the detection of the rotation angle adopts a structure that a photoelectric sensor directly detects the rotation position of the base, the structure of the rotation structure and the structure of the detection of the rotation angle are usually two mutually independent mechanisms, and the assembly of parts is very scattered and the mutually matched precision is poor.
In view of the above, it is necessary to design a rotation detection gear box structure for a card dispenser that has a simple structure, high stability, and low cost, and is capable of combining a rotation driving structure with a rotation angle detection structure. To this end, the inventors have advantageously devised that the technical solutions described below are created in this context.
