Description

Technical Field

[0001] This utility model relates to mahjong machine equipment, and more particularly to an improved tile-lifting device and the mahjong machine thereof. Background Technology

[0002] In automated card and board game equipment such as mahjong machines, the tile-lifting device is the core component for conveying and raising / lowering the tiles, and its stability affects equipment efficiency and user experience. Current mainstream devices utilize drives, turntables, and linkage components to automate tile processing. In the earlier developed push-up plate solution (patent pending but not published), the driven gear of the linkage component only had a notch without a retaining edge to achieve engagement and disengagement with the turntable. This design caused the guide post on the turntable to easily shift within the notch when it rotated to the plate-lifting position, resulting in turntable rotational vibration, which in turn caused plate conveying deviation, accelerated component wear, and operating noise, affecting device performance and user experience. Therefore, it is necessary to optimize the structure of the linkage components to solve the above problems, which is the core of the research and development of this improved device. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing an improved tile-lifting device and its mahjong machine.

[0004] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method: An improved card-lifting device includes a frame on which a driver, a turntable, a linkage assembly, and a card-lifting plate are mounted. The driver is driven by gears meshing with the turntable and the linkage assembly respectively. The other end of the linkage assembly is connected to the card-lifting plate and drives it to swing. The linkage assembly includes a driven gear, a cam, and a slider. The cam is fixed on the driven gear, and the driven gear drives the slider to make linear motion through the cam. The driven gear has an arc-shaped groove on its end face, and the turntable has a first guide post. When the first guide post moves in the arc-shaped groove, the teeth of the turntable disengage from the driven gear, the turntable does not rotate, and the lifting plate swings upward.

[0005] Preferably, one end of the arc-shaped groove is provided with a groove that communicates with it. When the first guide post moves into the groove, the groove drives the first guide post to move and drives the turntable to rotate, and the teeth of the turntable re-mesh with the driven gear.

[0006] Preferably, the driver is connected to a drive gear, which drives the drive gear to rotate. The driven gear includes a driven tooth section and a driven smooth tooth section. The drive gear meshes with the driven tooth section of the driven gear and drives the slider to move. When the drive gear is in the driven smooth tooth section, the slider does not move, and the end of the lifting plate descends to the designated position on the frame.

[0007] Preferably, the output shaft of the driver is equipped with a drive gear, and the driving gear is mounted on the frame via a pin, with the drive gear meshing with the driving gear.

[0008] Preferably, one end of the slider is provided with a first mounting groove, the bottom of the first mounting groove is provided with a first guide groove, a guide shaft is mounted on the cam, the guide shaft is adapted to the first guide groove, and the cam is installed in the first mounting groove.

[0012] A mahjong machine, including an improved tile-lifting device.

[0013] This utility model, by adopting the above technical solution, has significant technical effects: The curved groove on the end face of the driven gear has flanges on both sides, which allows the curved groove to reliably limit the first guide post of the turntable, effectively preventing the guide post from deviating and fundamentally solving the problem of rotational vibration of the turntable at the lifting plate in the original solution. At the same time, the first guide post and the curved groove are precisely matched to ensure the fit of their movements and ensure that the turntable stops stably at the lifting plate.

[0022] The following is in conjunction with the appendix Figure 1-7 The present invention will be further described in detail with reference to the embodiments.

[0023] Example 1 An improved tile-lifting device includes a frame 10, on which a driver 11, a turntable 12, a linkage assembly, and a tile-lifting plate 13 are mounted. The frame 10 has a tile storage slot for storing mahjong tiles. The turntable 12 is also equipped with a tile-pushing head. When the turntable 12 rotates, the tile-pushing head moves along the tile storage slot, thereby pushing the mahjong tiles into the tile-lifting plate 13. The driver 11 is a motor, which meshes with the turntable 12 and the linkage assembly through gears. The other end of the linkage assembly is connected to the tile-lifting plate 13 and drives it to swing. When the driver 11 is working, the turntable 12 is driven, and the tile-lifting plate 13 descends from the tabletop to the tile storage slot. The linkage component includes a driven gear 14, a cam 15, and a slider 16. The cam 15 is fixed on the driven gear 14. In this embodiment, the cam 15 is integrally formed on the driven gear 14. The driven gear 14 drives the slider 16 to make linear motion through the cam 15. The slider 16 moves back and forth and drives the lifting plate 13 to rise and fall. The driven gear 14 has an arc-shaped groove 141 on its end face, and there are retaining edges on both sides of the arc-shaped groove 141. The turntable 12 is provided with a first guide post 121. When the first guide post 121 moves in the arc-shaped groove 141, the arc-shaped groove 141 can guide and limit the first guide post 121. The teeth of the turntable 12 disengage from the driven gear 14, the turntable 12 does not rotate, and the lifting plate 13 swings and rises.

[0024] The arc-shaped groove 141 has flanges on both sides, which can reliably limit the first guide post 121 of the turntable 12, effectively preventing the first guide post 121 from deviating, and fundamentally solving the problem of rotational vibration of the turntable 12 at the lifting plate 13 in the original solution; the first guide post 121 and the arc-shaped groove 141 are precisely matched to ensure the fit of their movements, ensuring that the turntable 12 can stop stably and without shaking when the first guide post 121 moves in the arc-shaped groove 141; it reduces the wear of components such as the turntable 12 and the driven gear 14, and also reduces operating noise, comprehensively optimizing the operating stability, service life and user experience of the device.

[0025] One end of the arc-shaped groove 141 is provided with a groove 142 communicating with it. When the first guide post 121 moves into the groove 142, the groove 142 drives the first guide post 121 to move and drives the turntable 12 to rotate. The teeth of the turntable 12 re-mesh with the driven gear 14. When the tile-lifting plate 13 descends to the designated position, the turntable 12 rotates and pushes the mahjong tiles in the frame 10 onto the tile-lifting plate 13. When the turntable 12 is not rotating through meshing, the fit between the first guide post 121 and the groove 142 is a relatively optimal structure. When the turntable 12 is not rotating through engagement, the matching structure of the first guide post 121 and the groove 142 can stably restrict the state of the turntable 12, preventing it from rotating accidentally and ensuring a precise connection for subsequent engagement. This optimizes transmission continuity. When the groove 142 drives the first guide post 121, it can smoothly drive the turntable 12 to resume rotation and guide the teeth of the turntable 12 to precisely re-engage with the driven gear 14, reducing component wear and operating noise. This ensures that the mahjong tiles in the frame 10 are efficiently and stably pushed to the tile-lifting plate 13, comprehensively improving the reliability of the device and the efficiency of tile processing.

[0026] The driver 11 is connected to the drive gear 17, which drives the drive gear 17 to rotate. The driven gear 14 includes a driven tooth section 143 and a driven smooth tooth section 144. The drive gear 17 meshes with the driven tooth section 143 of the driven gear 14 and drives the slider 16 to move. When the drive gear 17 is in the driven smooth tooth section 144, the driven gear 14 does not rotate and the slider 16 does not move. The end of the tile-lifting plate 13 descends to the designated position of the frame 10. The drive gear 17 meshes with the turntable 12. The pusher on the turntable 12 pushes the mahjong tiles on the frame 10 into the tile-lifting plate 13.

[0027] The output shaft of the driver 11 is equipped with a drive gear 22, and the drive gear 17 is mounted on the frame 10 via a pin. The drive gear 22 meshes with the drive gear 17. The driver 11 drives the drive gear 17 to rotate via the drive gear 22. The turntable 12 and the driven gear 14 transmit power through the drive gear 17, thereby allowing the position of the driver 11 mounted on the frame 10 to be adjusted.

[0028] The slider 16 has a first mounting groove 161 at one end, and a first guide groove 162 at the bottom of the first mounting groove 161. A guide shaft 18 is mounted on the cam 15, and the guide shaft 18 is adapted to the first guide groove 162. The cam 15 is installed in the first mounting groove 161. The precise adaptation of the guide shaft 18 and the first guide groove 162 further constrains their motion trajectory, ensuring that the cam 15 can stably drive the slider 16 to make linear motion when rotating, preventing transmission jamming. The motion transmission is more precise. The adaptation and sliding of the guide shaft 18 in the first guide groove 162 can efficiently convert the circular motion of the cam 15 into the linear motion of the slider 16, reduce power transmission loss, ensure the accuracy of the slider 16's motion stroke, and thus ensure that the swing amplitude and position of the lifting plate 13 are precisely controllable.

[0029] A cover plate 19 is installed on the lower end face of the frame 10, covering the slider 16 onto the frame 10. A second guide post is provided between the cover plate 19 and the frame 10, and a slide groove 163 is provided on the slider 16. The second guide post and the slide groove 163 are adapted to each other. This achieves efficient motion guidance. The adapted structure of the second guide post and the slide groove 163 can precisely constrain the linear motion of the slider 16, preventing the slider 16 from shifting laterally or wobbling under the drive of the cam 1, ensuring that the slider 16 always moves along the preset trajectory, thereby ensuring the accuracy of the swing amplitude and position of the lifting plate 13.

[0030] The lifting plate device also includes a swing arm 20. A slider 16 drives the lifting plate 13 to rise and fall via the swing arm. The other end of the slider 16 has a second mounting groove 164. A straight tooth 165 is provided on the lower side wall of the second mounting groove 164. One end of the swing arm 20 has a rod tooth 201 and a rod polished tooth 202. The straight tooth 165 meshes with the rod tooth 201, causing the swing arm 20 to swing. The upper side wall of the second mounting groove 164 contacts and connects with the rod polished tooth 202. This enhances meshing stability and limiting capability. The contact connection between the upper side wall of the second mounting groove 164 and the rod polished tooth 202 forms a longitudinal limit on the swing arm 20. Combined with the lateral constraint of the straight tooth meshing, this effectively prevents the swing arm 20 from shifting vertically during swinging, reducing tooth wear. Simultaneously, stable movement of the swing arm 20 can be achieved without an additional limit switch.

[0031] A guide seat 21 is fixed to the lower end face of the lifting plate 13. The guide seat 21 is provided with a second guide groove. The other end of the swing rod 20 is installed in the second guide groove. The swing rod 20 moves in the second guide groove and drives the lifting plate 13 to swing.

[0032] Example 2 Example 2 is basically the same as Example 1, except that the cam 15 is fixed to the driven gear 14 by fasteners, so that the cam 15 and the driven gear 14 form a whole and rotate synchronously.

[0033] Example 3 A mahjong machine includes an improved tile-lifting device as described in embodiment 1 or 2.
