Description

Technical Field

[0001] This utility model belongs to the field of mahjong machines, and in particular relates to a card-collecting wheel for a mahjong machine. Background Technology

[0002] The mahjong machine's tile-collecting wheel is a crucial component of the automatic mahjong machine's tile-collecting and feeding mechanism. It picks up the shuffled mahjong tiles from the shuffling tray and delivers them to the entrance of the tile conveyor. The tiles are then fed by a conveyor belt into the stacking mechanism for stacking. To facilitate tile transport, a common method involves placing magnets inside the tiles and corresponding magnets on the tile-collecting wheel. The tiles are attracted by the magnets and thus transported by the conveyor belt. However, during the upward rotation of the tile-collecting wheel, the tiles' weight and the weakening of the magnets due to prolonged use cause them to slide, resulting in positional shifts relative to the wheel.

[0003] For example, a Chinese invention patent discloses a card-collecting wheel assembly, a card-feeding device, and an automatic mahjong machine [application number CN202021341610.5]. The card-collecting wheel assembly includes a card-collecting wheel with a card-collecting magnet and a card-blocking plate disposed at one end of the card-collecting wheel. The card-collecting wheel assembly also includes a first buffer part, which is integrally formed with the card-blocking plate and faces the end of the card-collecting wheel away from the card-blocking plate. The first buffer part reduces the impact of the mahjong tiles on the card-blocking plate when the card-collecting wheel attracts the mahjong tiles. When the mahjong tiles come into contact with the first buffer part, their impact on the card-blocking plate is weakened by the first buffer part, thereby reducing the noise when the mahjong tiles hit the card-blocking plate. However, this technical solution suffers from weakening of the magnet's magnetism due to prolonged use, and because the mahjong tiles have a certain weight, the mahjong tiles may slide, causing them to shift relative to the card-collecting wheel. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing a card-collecting wheel for a mahjong machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A card-collecting wheel for a mahjong machine includes a cylindrical wheel body with several magnetic attractors on it. The outer surface of the wheel body has several planes distributed in a circumferential direction, and each plane has a window. Inside the wheel body, there are several magnetic mounting sleeves corresponding to the windows. The magnetic mounting sleeves are integrally formed with the wheel body. The windows communicate with the inner cavity of the magnetic mounting sleeves. One end of the magnetic mounting sleeve is closed, and the other end has an insertion port. The magnetic attractors are fixed inside the magnetic mounting sleeves, and the upper surface of the magnetic attractors is lower than the upper edge of the windows.

[0007] In the aforementioned mahjong machine's card-collecting wheel, a mounting sleeve is provided at the center of the wheel body, and a magnet mounting sleeve is located between the inner side of the wheel body and the mounting sleeve. The magnet mounting sleeve and the mounting sleeve are integrally formed.

[0008] In the aforementioned mahjong machine's card-collecting wheel, one end of the wheel body is provided with a mounting flange, the mounting sleeve is integrated with the mounting flange, and the insertion port of the magnet mounting sleeve is on the same side as the mounting flange.

[0009] In the aforementioned mahjong machine's card-collecting wheel, an annular step is formed between the outer surface of one end of the wheel and the plane. A conveyor belt located outside the window is wound around the wheel. One side of the conveyor belt is adjacent to the annular step, and the other side extends to the other end of the wheel. The thickness of the conveyor belt is adapted to the height of the annular step.

[0010] In the aforementioned mahjong machine's card-collecting wheel, the wheel body is installed between a first mounting component and a second mounting component. The first mounting component has a recessed groove, and the mounting flange is located within the recessed groove. The other end of the wheel body is adjacent to the second mounting component, and the other side of the conveyor belt is adjacent to the second mounting component, thereby forming a conveyor belt accommodating space between the second mounting component and the annular step.

[0011] The aforementioned mahjong machine's card-collecting wheel also includes a card-feeding channel. The entrance of the card-feeding channel is higher than the wheel body, and an inclined platform is provided between the card-feeding channel and the wheel body. The inclined platform is mounted on the first mounting component.

[0012] In the aforementioned mahjong machine's card-collecting wheel, there are gaps between the inclined platform, the card-feeding channel, and the wheel body.

[0013] In the aforementioned mahjong machine's card-collecting wheel, the side of the inclined table has a guide plate mounted on the first mounting component. The card-feeding channel entrance extends to the guide plate, and the outer surface of the guide plate facing the card-feeding channel is curved, making the entrance of the card-feeding channel narrow.

[0014] In the aforementioned mahjong machine's card-collecting wheel, the wheel body is connected to the output shaft of a rotating motor fixed on a second mounting component, with the rotating motor and the wheel body located on opposite sides of the second mounting component.

[0015] In the aforementioned mahjong machine's card-collecting wheel, the second mounting component has a notch, and the opening of the inner cavity of the magnet mounting sleeve is fully exposed at the notch. The rotating motor is fixed to the second mounting component by bolts.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] 1. The mahjong tiles are attracted by the magnetic body and placed in the gap between the magnetic body and the window. The gap restricts the mahjong tiles from all sides. If the attraction is insufficient or the mahjong tiles slide relative to the conveyor belt during the process, the side walls around the window will block the sliding of the mahjong tiles, thus ensuring that the mahjong tiles can be transported smoothly.

[0018] 2. The curved surface of the annular step fits into the conveyor belt, increasing the contact area between the wheel and the conveyor belt, thus enabling the conveyor belt to move stably and preventing it from jumping.

[0019] 3. Generally, the width of the conveyor belt is greater than the width of the mahjong tiles. If the size of the mahjong tiles is larger than the window size, anti-vibration pads can be laid in the gap between the window and the magnetic body. By sacrificing the gap to limit the sliding of the mahjong tiles, the mahjong machine can improve its adaptability to different tile sizes. Also, when using larger mahjong tiles, the tiles will collide with the wheels during the adsorption process, causing vibrations. Anti-vibration pads can reduce these vibrations.

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] This utility model provides a card-collecting wheel for a mahjong machine, combined with... Figure 1-5As shown, the device includes a cylindrical wheel body 10 with several magnetic attractors on it. The outer surface of the wheel body 10 has several planes 11 distributed in the circumferential direction, and each plane 11 has a window 12. Inside the wheel body 10, there are several magnetic mounting sleeves 13 corresponding to the windows 12. The magnetic mounting sleeves 13 are integrally formed with the wheel body 10. The windows 12 communicate with the inner cavities of the magnetic mounting sleeves 13. One end of the magnetic mounting sleeve 13 is closed, and the other end has an insertion port. The magnetic attractors are fixed inside the magnetic mounting sleeves 13, and the upper surface of the magnetic attractors is lower than the upper edge of the windows 12.

[0028] In this embodiment, the magnetic accumulator is inserted into the magnetic mounting sleeve 13 through the insertion port at one end of the magnetic mounting sleeve 13. The magnetic accumulator is inserted into the window 12 and the upper surface of the magnetic accumulator is lower than the upper edge of the window 12. The conveyor belt is sleeved on the outer surface of the wheel body 10. When the card suction is working, the mahjong tile is attracted by the magnetic accumulator and the mahjong tile is placed in the gap between the magnetic accumulator and the window 12. The gap creates a restriction around the mahjong tile. If the attraction force is insufficient or the mahjong tile slides relative to the conveyor belt during the conveyor belt process, the side walls around the window 12 will block the sliding of the mahjong tile, so that the mahjong tile can be transported smoothly.

[0029] The wheel body 10 has a mounting sleeve 14 at its center, and the magnet mounting sleeve 13 is located between the inner side of the wheel body 10 and the mounting sleeve 14. The magnet mounting sleeve 13 and the mounting sleeve 14 are integrally formed.

[0030] The wheel body 10 is provided with a mounting flange 15 at one end, the mounting sleeve 14 is integrated with the mounting flange 15, and the insertion port of the magnet mounting sleeve 13 is on the same side as the mounting flange 15.

[0031] In this embodiment, it is integrally manufactured for easy installation into the mahjong machine and for easy placement of the magnetic body into the magnetic mounting sleeve 13.

[0032] An annular step 16 is formed between the outer surface of one end of the wheel body 10 and the plane 11. A conveyor belt located outside the window 12 is wound around the wheel body 10. One side of the conveyor belt is adjacent to the annular step 16, and the other side extends to the other end of the wheel body 10. The thickness of the conveyor belt is adapted to the height of the annular step 16.

[0033] In this embodiment, the conveyor belt is fitted onto the outer surface of the annular step 16. The curved surface of the annular step 16 fits the conveyor belt, increasing the contact area between the wheel 10 and the conveyor belt, so that the conveyor belt can move stably and prevent the conveyor belt from jumping.

[0034] The wheel 10 is installed between the first mounting member 17 and the second mounting member 18. The first mounting member 17 is provided with a groove 19, and the mounting flange 15 is located in the groove 19. The other end of the wheel 10 is adjacent to the second mounting member 18, and the other side of the conveyor belt is adjacent to the second mounting member 18, thereby forming a conveyor belt accommodating space 20 between the second mounting member 18 and the annular step 16.

[0035] In this embodiment, the width of the conveyor belt is generally greater than the width of the mahjong tiles. If the size of the mahjong tiles is larger than the size of the window 12, a shock-absorbing pad can be laid in the gap between the window 12 and the magnetic body. By sacrificing the gap to limit the sliding of the mahjong tiles, the mahjong machine can improve its adaptability to different mahjong tile sizes. When using larger mahjong tiles, the mahjong tiles will collide with the wheel 10 during the adsorption process, causing vibration. The shock-absorbing pad can reduce the vibration.

[0036] It also includes a license plate channel 21, the entrance of which is higher than the wheel body 10, and an inclined platform 22 is provided between the license plate channel 21 and the wheel body 10. The inclined platform 22 is mounted on the first mounting component 17.

[0037] In this embodiment, the tilted platform 22 allows the mahjong tiles to be stably transferred into the tile-laying channel 21, preventing the mahjong tiles from vibrating and shifting due to large drop differences.

[0038] There are gaps between the inclined platform 22, the license plate channel 21, and the wheel body 10.

[0039] In this embodiment, if there is no gap between the inclined platform 22 and the card-loading channel 21 and the wheel 10, the shape of the conveyor belt will have more obvious rhomboids and the conveyor belt will be more prone to wear. The gap between them makes the conveyor belt smooth in the turning direction.

[0040] The inclined platform 22 has a guide plate 23 on the side of the first mounting member 17. The entrance of the license plate loading channel 21 extends to the guide plate 23, and the outer surface of the guide plate 23 facing the license plate loading channel 21 is curved, making the entrance of the license plate loading channel 21 narrow.

[0041] In this embodiment, when the mahjong tiles are transferred to the tile-loading channel 21, the guide plate 23 can push those mahjong tiles that are out of position to the correct position, preventing the mahjong tiles from colliding with the inner wall of the tile-loading channel 21 and getting stuck.

[0042] The wheel 10 is connected to the output shaft of a rotating motor fixed on the second mounting member 18, and the rotating motor and the wheel 10 are located on opposite sides of the second mounting member 18.

[0043] The second mounting component 18 is provided with a notch 25, and the opening of the inner cavity of the magnet mounting sleeve 13 can be fully exposed at the notch 25. The rotating motor is fixed to the second mounting component 18 by bolts.

[0044] In this embodiment, when the magnetism of the magnetic accumulator weakens and needs to be replaced, the rotating motor is removed and the wheel 10 is manually rotated to replace the magnetic accumulator through the notch 25.

[0045] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0046] Although this article frequently uses terms such as wheel body 10, plane 11, window 12, magnet mounting sleeve 13, mounting sleeve 14, mounting flange 15, annular step 16, first mounting component 17, second mounting component 18, trough 19, conveyor belt accommodating space 20, license plate passage 21, inclined platform 22, guide plate 23, and notch 25, these terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would contradict the spirit of this utility model.
