Technical Field

[0001] The utility model relates to the field of automatic mahjong machine equipment, and particularly relates to a silent assembly structure of a card suction wheel of a mahjong machine. Background Art

[0002] As an automated card shuffling and dealing device, the automatic mahjong machine has been widely used in the market. Its core function is to realize the automatic shuffling, sorting and dealing of mahjong tiles through mechanical structures and electronic controls. In the design of traditional mahjong machines, the card suction wheel is usually made of hard materials, and magnets are equipped on its outer peripheral surface to adsorb mahjong tiles. Although this design improves the durability of the card suction wheel, it also causes a significant problem - noise. When the mahjong tiles are adsorbed by the hard card suction wheel, they will collide with it and generate noise. Especially in an indoor environment, this noise will become more prominent, thus affecting the user's gaming experience and comfort.

[0003] To solve this problem, the utility model proposes a silent assembly structure of a card suction wheel of a mahjong machine. Summary of the Utility Model

Detailed implementation mode

[0021] The present utility model will be further described in detail below in conjunction with the drawings and through embodiments. The following embodiments are explanations of the present utility model, and the present utility model is not limited to the following embodiments.

[0022] See Figure 1 - Figure 4 In this embodiment, a silent assembly structure of a card-sucking wheel of a mahjong machine is involved, which is specifically used to effectively reduce the noise generated by the card-sucking wheel during the card-sucking process. Specifically, it includes a rigid wheel body 1 and a flexible gasket 2 sleeved on the wheel body 1. A limiting ring 11 is provided at one end of the wheel body 1, and a limiting plate 12 is provided at the other end. The gasket 2 is located between the limiting ring 11 and the limiting plate 12, and strip-shaped protrusions 24 are provided on both the inner and outer sides of the gasket 2.

[0023] Specifically, in this embodiment, to ensure the overall strength of the card-sucking wheel, the wheel body 1 is made of rigid plastic to improve the durability of the card-sucking wheel. The gasket 2 is made of a flexible material (such as rubber, silicone and other soft plastics). The gasket 2 is wrapped on the outer surface of the wheel body 1 to buffer the collision of the mahjong tiles on the outer surface of the wheel body 1 during the adsorption process. The outer diameter of the limiting ring 11 is smaller than the outer diameter of the limiting plate 12. The gasket 2 is sleeved from one side of the limiting ring 11 of the wheel body 1. Rubber and silicone have good elasticity. When the gasket 2 is stretched and undergoes elastic deformation, when it is sleeved on the outer surface of the wheel body 1, elastic recovery occurs, making it firmly fit with the outer surface of the wheel body 1. A limiting plate 12 is provided at the other end of the wheel body 1, so that the gasket 2 is sleeved between the limiting ring 11 and the limiting plate 12 to complete the assembly process of the gasket 2. In this embodiment, one end of the gasket 2 is glued to the limiting plate 12, which can further improve the assembly stability between the gasket 2 and the wheel body 1. In addition, strip-shaped protrusions 24 are distributed on both the inner and outer sides of the gasket 2 to further strengthen the buffering effect of the gasket 2, thereby realizing the silent effect when the card-sucking wheel adsorbs mahjong tiles. Through the above structure and the connection relationship therebetween, a silent assembly structure of a card-sucking wheel of a mahjong machine according to the present utility model is formed, which can effectively reduce the noise generated by the card-sucking wheel during the card-sucking process, providing a more comfortable entertainment environment for users. Especially when used indoors, the use experience of the mahjong machine is significantly improved.

[0024] The described wheel body 1 is provided with a shaft hole 13. A plurality of groups of magnetic attraction parts 14 and support parts 15 are sequentially connected circumferentially on the outer side of the shaft hole 13. The gasket 2 is provided with a flat surface part 21 that is in contact and adaptation with the magnetic attraction part 14 and an arc surface part 22 that is in contact and adaptation with the support part 15. In this embodiment, the shaft hole 13 is used to connect the shaft of a driving motor 31 that drives the wheel body 1 to rotate. The magnetic attraction part 14 is the part of the wheel body 1 for installing a magnet 32. After the magnet 32 of the magnetic attraction part 14 is installed, a plane is formed. The inner surface of the flat surface part 21 of the gasket 2 is also a flat surface. The support part 15 has an arc-shaped profile and is used to support the gasket 2. The inner surface of the arc surface part 22 of the gasket 2 also has an arc-shaped profile. Therefore, after assembly, the flat surface part 21 of the gasket 2 is in close fit with the magnetic attraction part 14 of the wheel body 1, and the arc surface part 22 of the gasket 2 is in close fit with the support part 15 of the wheel body 1, making the overall assembly structure airtight and the connection between the wheel body 1 and the gasket 2 more compact.

[0025] A sharp edge 16 is provided between the magnetic attraction part 14 and the support part 15, and a folded edge 23 is provided between the flat surface part 21 and the arc surface part 22. The sharp edge 16 and the folded edge 23 are in contact and cooperation. In this embodiment, on the wheel body 1, the transition position between the magnetic attraction part 14 and the support part 15 is the sharp edge 16. Correspondingly, for the gasket 2, a folded edge 23 (the turning of the inner surface of the gasket 2) is provided at the transition position between the flat surface part 21 and the arc surface part 22. During the operation of the card-sucking wheel, in order to convey the mahjong cards to the mahjong machine tabletop, a belt 33 for conveying the mahjong cards needs to be sleeved on the card-sucking wheel. The card-sucking wheel is driven by the motor 31, and the conveying movement of the belt 33 needs to be provided by the friction between the card-sucking wheel and it. Therefore, there is an inevitable tendency of relative rotation between the wheel body 1 and the gasket 2, and there is a frictional effect. The sharp edge 16 of the wheel body 1 is in close fit with the folded edge 23 of the gasket 2, and the folded edge 23 has a biting effect on the sharp edge 16. On the basis of ensuring the close fit between the gasket 2 and the wheel body 1, it can also prevent the relative rotation between the wheel body 1 and the gasket 2, effectively reducing the wear of the gasket 2 caused by the friction generated by their relative rotation.

[0026] See Figure 5 , the wheel body 1 is provided with three / four magnetic attraction parts 14, and the gasket 2 correspondingly is also provided with three / four groups of flat surface parts 21. Considering the actual size of the mahjong cards to ensure that the card-sucking wheel can effectively contact and adsorb the mahjong cards. For small-sized mahjong cards, the wheel body 1 usually adopts a design with four magnetic attraction parts 14 (see Figure 5) Correspondingly, the gasket 2 is also provided with three groups of flat portions 21. However, for large-sized mahjong tiles, when the size of the wheel body 1 remains the same, the design of the four magnetic attraction portions 14 results in a relatively small area of a single magnetic attraction portion 14, which cannot meet the adsorption of the large-sized mahjong tiles by the wheel body 1. At this time, the number of magnetic attraction portions 14 on the wheel body 1 should be set to three, and the flat portions 21 of the gasket 2 are also designed into three groups. The design of the three magnetic attraction portions 14 makes the area of a single magnetic attraction portion 14 larger than before, so as to meet the adsorption effect of the wheel body 1 on the large-sized mahjong tiles.

[0027] See Figure 6 , the magnetic attraction portion 14 is provided with a groove body 141, a magnet 32 is installed in the groove body 141, a first soft package layer 321 is pasted on the front side of the magnet 32, and a second soft package layer 322 is pasted on the rear side. A notch 121 is provided behind the limiting plate 12, the notch 121 communicates with the groove body 141, a U-shaped plate 34 is installed in the groove body 141, and a third soft package layer 341 is pasted on the side of the U-shaped plate 34 in contact with the groove body 141, and a magnet 32 is installed in the groove of the U-shaped plate 34. In this embodiment, the magnet 32 is fixed in the U-shaped plate 34 by bonding or other means, and the U-shaped plate 34 is fastened and fixed in the groove body 141 by a buckle 122 at the notch 121. By pasting the first soft package layer 321 on the outside of the magnet 32 and the second soft package layer 322 on the inside, and a third soft package layer 341 is pasted on the side of the U-shaped plate 34 in contact with the groove body 141, when the mahjong tile is adsorbed by the magnet 32, it collides with the gasket 2 outside it (the collision process between the mahjong tile and the outer belt 33 of the gasket 2 is omitted here). After the first buffering by the gasket 2, the gasket 2 collides with the magnet 32. After the second buffering by the first soft package layer 321 outside the magnet 32, the magnet 32 collides with the U-shaped plate 34. At this time, the second soft package layer 322 inside the magnet 32 produces a third buffering effect. Finally, it comes to the collision between the U-shaped plate 34 and the groove body 141. The setting of the third soft package layer 341 inside the U-shaped plate 34 forms a fourth buffering effect. Connecting the above-mentioned multiple buffering effects can reduce the noise generated when the mahjong tile collides with the card suction wheel. The first soft package layer 321 and the third soft package layer 341 of this embodiment are made of materials such as flannelette, sponge, and rubber that can absorb impact and reduce noise.

[0028] The height of the gasket 2 is not greater than the height of the wheel body 1. In this embodiment, the height of the wheel body 1 refers to the distance between the limit ring 11 and the limit plate 12. To ensure a better assembly effect, the height of the gasket 2 should not be greater than this distance, and it is best if they are equal, so that the assembled gasket 2 can be completely located between the limit ring 11 and the limit plate 12. When the height of the gasket 2 is too long, two adverse situations may occur: one end of the gasket 2 contacts the limit plate 12, and the other end covers the outer surface of the limit ring 11 or even extends beyond the end of the limit ring 11. At this time, there is a risk that the gasket 2 may detach from the wheel body 1; both ends of the gasket 2 are located between the limit ring 11 and the limit plate 12, but this will cause the middle part of the gasket 2 to arch. Since the belt 33 is sleeved on the outer surface of the gasket 2 and will exert pressure on the gasket 2, the arched part of the gasket 2 cannot form an effective fit with the belt 33, and in the long term, it may cause uneven wear of the belt 33 or even the possibility that the belt 33 detaches from the gasket 2.

[0029] The above content described in this specification is only an example of the present utility model. Those skilled in the technical field to which the present utility model belongs can make various modifications or supplements to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the content of this specification of the present utility model or exceed the scope defined by this claim book, they should all belong to the protection scope of the present utility model.
