Abstract
Description
Technical Field
[0001] This utility model relates to the field of mahjong machine structure, and in particular to a mahjong machine structure with a multi-motor cooperative layout and a gearbox for speed change. Background Technology
[0002] Mahjong machines, as entertainment devices integrating mechanical transmission and automatic control technologies, are widely used in home entertainment and commercial leisure venues. With users' increasing demands for entertainment experiences, the shuffling efficiency, operational stability, and reliability of mahjong machines have become core performance indicators. The core working process revolves around the shuffling turntable, which is driven by a motor-driven transmission structure to rotate, thus mixing, arranging, and conveying the mahjong tiles. The design of the transmission components directly determines the smoothness of the shuffling process and the overall lifespan of the machine. Therefore, optimizing the transmission structure to improve performance has become an important direction for the technological development of mahjong machines.
[0003] The shuffling turntable transmission components of existing traditional mahjong machines generally employ a single-motor, single-stage gear transmission mechanical structure. The technical principle is as follows: the output shaft of a single drive motor is rigidly connected to a motor gear. After the motor starts, it drives the motor gear to rotate. This motor gear directly meshes with a large disc gear (external gear structure) fixed to the bottom of the shuffling turntable. Through the meshing transmission between the gears, the motor's power is transmitted to the large disc gear, thereby driving the shuffling turntable to rotate and complete the stirring and mixing of the mahjong tiles. The entire transmission process relies solely on a single motor for power, and the transmission path only includes the meshing relationship between the motor gear and the large disc gear. This single-stage transmission achieves the conversion of motor speed to turntable speed and the transmission of power.
[0004] Existing traditional mahjong machines employ a single-motor, single-stage gear transmission structure, which suffers from insufficient transmission torque. Because it relies solely on a single motor for power output, and lacks a multi-stage transmission structure to amplify the torque, when the number of mahjong tiles in the shuffling turntable is large or unevenly distributed, the power output from the motor, after being transmitted through the single-stage gear, is insufficient to provide enough rotational torque to drive the turntable smoothly. This easily leads to the turntable jamming or stalling during shuffling, or insufficient rotational force causing uneven mixing of the mahjong tiles, directly affecting shuffling efficiency and user experience. Therefore, this paper proposes a mahjong machine structure with a multi-motor collaborative layout and gearbox speed change to solve these problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a mahjong machine structure with a multi-motor cooperative layout and gearbox speed change, aiming to improve the problem of shuffling jams or unevenness caused by insufficient transmission force of a single gear in traditional mahjong machines.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0033] Reference Figures 1-6 This utility model provides an embodiment of a mahjong machine structure with a multi-motor cooperative layout and gearbox speed change, including an iron plate 1. A bearing 3 is fixedly connected inside the iron plate 1. The bearing 3 provides a fixed central axis for the rotation of the turntable 2, ensuring precise concentricity of the rotational motion. The turntable 2 is mounted on the outer wall of the bearing 3. A fixing frame 7 is fixedly connected to the bottom of the turntable 2. The integrated design of the fixing frame 7 and the internal gear ring 6 is used to collect the driving force transmitted by all the single gears 5 and evenly apply the concentrated power to the bottom of the turntable 2. The internal gear ring 6 is fixedly connected to the inner wall of the fixing frame 7. Multiple motors 4 are fixedly connected to the bottom of the iron plate 1. Multiple motors 4 mesh with single gears 5 at their output ends for transmission. By intelligently controlling the speed and direction of the motors 4, the internal gear ring 6 can be flexibly driven and its speed adjusted. Each motor 4 has a single gear 5 fixedly connected to its output end. Multiple gear sets 16 are rotatably connected to the top of the iron plate 1. Each gear set 16 is composed of a small bottom gear and a large top gear. The small bottom gear of each gear set 16 meshes with the single gear 5. The large top gear of the multiple gear sets 16 meshes with the inner wall of the internal gear ring 6. By using multiple gear sets 16, the torque is reduced, allowing the motors 4 to achieve the same rotational effect as the turntable 2 at a slower speed.
[0034] A positioning ring 9 is fixedly connected to the outer wall of the bearing seat 3. The positioning ring 9 provides a standard circumferential track surface to limit and guide the rotational movement of the connecting cover 10. Connecting covers 10 are rotatably connected to both sides of the positioning ring 9. The connecting covers 10 cooperate with the positioning ring 9 to achieve stable circumferential rotational movement, thereby transferring the radial load of the turntable 2 to the fixed bearing seat 3 and effectively distributing the lateral force generated when the turntable 2 rotates at high speed. Multiple connecting plates 12 are provided at the connection between the two connecting covers 10. The connecting plates 12 are connected and fixed to the connecting covers 10 on both sides by bolts, which are used to fasten the split connecting covers 10 into a complete ring support structure, enhancing the structural strength and stability of the connecting covers 10. Multiple support plates 11 are fixedly connected to the top of each connecting cover 10. Connecting rings 8 are provided on the top of the multiple support plates 11. The connecting rings 8 are firmly connected to the connecting covers 10 through the support plates 11, and their outer walls are fixedly connected to the inner wall of the turntable 2, realizing the connection of the entire ring. The supporting components rotate synchronously with the turntable 2 and provide circumferential support. The connecting ring 8 has a circular structure to ensure uniform distribution of the supporting force. Multiple connecting strips 13 are slidably connected at the connection between the two connecting covers 10. The connecting strips 13 act as vertical reinforcing ribs and work with the connecting ring 8 to limit sliding in the up and down directions, achieving a stable effect to prevent the turntable 2 from axial movement or tilting during rotation. The top ends of the multiple connecting strips 13 extend through to the top of the connecting ring 8, and the bottom ends of the multiple connecting strips 13 are fixedly connected to the outer wall of the bearing seat 3. Each connecting strip 13 has a threaded post 14 fixedly connected to its top end, and each threaded post 14 has a nut 15 threadedly connected to its outer wall. The nuts 15 are used to adjust the tightness of the fit with the top of the connecting ring 8. By tightening or loosening, the installation gap can be precisely eliminated, providing a fine-tuning guarantee for the smooth operation of the turntable 2. The multiple nuts 15 fit against the top of the connecting ring 8, together forming an axial locking structure to prevent the turntable 2 from floating or sinking, ensuring the ultimate stability of the equipment operation.
[0035] Working principle: During equipment use, motor 4 is started, and the output end of motor 4 drives single gear 5 to rotate. Single gear 5 transmits the rotational force to the surface of the small gear at the bottom of gear set 16, thereby driving the large gear at the top of gear set 16 to rotate on the inner wall of the inner gear ring 6. Since the large gear at the top of gear set 16 meshes with the inner wall of the inner gear ring 6, it drives turntable 2 to rotate, thereby increasing the transmission torque. This makes the turntable 2 rotate with greater force at the same speed at the output end of motor 4, solving the problem that traditional equipment usually drives turntable 2 to rotate through a single motor and a single gear, which is prone to insufficient force.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
