Problems solved by technology

[0006] The disadvantages of the above-mentioned noise-reducing air leaf device are: (1) it is difficult to eliminate or reduce the noise generated by mahjong tiles colliding with bowls, brackets and lifting rods; Noise due to collision
[0007] It can be seen that although the noise reduction measures in the existing mahjong machines are in various poses and with different expressions, there is no noise reduction measure that can eliminate the mahjong tiles on the shuffle board. The big impact collides with other mahjong tiles and produces a lot of noise

Embodiment 1

[0067] Such as figure 1 and figure 2 and image 3 As shown, a kind of mahjong machine noise reduction system in the present embodiment includes a slow-down device 100 and a shuffling device 200, wherein the slow-down device 100 includes a jacking mechanism 7, and the jacking mechanism 7 includes a lifting rod 71; Figure 10 As shown, the card shuffling device 200 includes a card shuffling tray 1 and a central shaft seat 2 located in the center of the card shuffling tray 1. The card shuffling tray 1 is rotationally connected to the central shaft seat 2, and the lifting rod 71 is passed through the central shaft The center of seat 2 and elevating rod 71 pass through the top of central shaft seat 2 and are fixedly installed with carriage 72, holder bowl 73 and dice dish figure successively (not shown in the figure) from bottom to top); The size of the card drop channel (not shown) is comparable. The dice tray, the supporting bowl 73, the bracket 72 and the lifting rod 71 are ...

Embodiment 2

[0093] This embodiment is a noise reduction system for a mahjong machine. The structure of the noise reduction system is basically the same as that of Embodiment 1, except for the synchronous transmission member 10 between the noise reduction cover 8 and the card player 3 . Such as Figure 15 , Figure 16 , Figure 17 and Figure 18 As shown, the synchronous transmission member 10 of this embodiment includes a funnel-shaped ring gear seat 101, the flaring end of the ring gear seat 101 is fixedly connected with the inner peripheral wall of the cylindrical part 82, and the narrow mouth end of the ring gear seat 101 Extending to the outer periphery of the lifting rod 71; the side of the ring gear seat 101 facing the bracket 72 is in conflict with the bracket 72, and the side of the ring gear seat 101 facing away from the bracket 72 is fixed with a driven outer ring gear 104; the fourth A driving inner ring gear 105 meshing with the driven outer ring gear 104 is provided at the t...

Embodiment 3

[0095] This embodiment is a noise reduction system for a mahjong machine. The structure of the noise reduction system is basically the same as that of Embodiment 1, except that no synchronous transmission member 10 is provided between the noise reduction cover 8 and the card player 3 . Such as Figure 19 , Figure 20 , Figure 21 and Figure 22 As shown, the noise reduction cover 8 is in the process of pressing the card position, and the rotation of the noise reduction cover 8 is only driven by the friction between the umbrella portion 81 and the mahjong tiles.

Abstract

The invention discloses a noise reduction system of a mahjong machine. The noise reduction system comprises a slow descending device, the slow descending device comprises a jacking mechanism used for driving a dice plate to ascend and descend, the periphery of the jacking mechanism is provided with a noise reduction cover synchronously ascending and descending along with the jacking mechanism, and the noise reduction cover comprises an umbrella-shaped part extending from the periphery of the jacking mechanism to the outer periphery of a shuffling large plate. The projection radiuses of the mahjong falling channel, the umbrella-shaped part and the large shuffling plate in the vertical direction are sequentially increased; and the umbrella-shaped part is provided with a mahjong receiving position which ascends along with the ascending of the jacking mechanism to slow down the speed reduction of the mahjong tiles, and a mahjong pressing position which descends along with the jacking mechanism to cover the shuffling large plate to extrude the mahjong tiles. When the mahjong tiles are shuffled, the mahjong tiles on the tabletop firstly fall onto the umbrella-shaped part at the mahjong tile receiving position, and then fall onto the large shuffling plate from the umbrella-shaped part, so that the mahjong tile falling noise is eliminated or reduced; and in the shuffling process, the mahjong tiles are subjected to pressure from the umbrella-shaped parts above, so that the shuffling noise is greatly reduced, and the shuffling noise is prevented from being upwards transmitted to the upper part of the table top.

Description

technical field [0001] The invention belongs to the technical field of mahjong machines, in particular to a noise reduction system for a mahjong machine. Background technique [0002] When the mahjong tiles are pushed from the desktop into the shuffling tray, not only will they collide with the supporting structure of the dice tray and generate noise, but also due to the large drop between the desktop and the shuffling tray, the mahjong tiles will There will also be a lot of noise after the board is shuffled; at the same time, during the process of shuffling the board and rotating the shuffling board, the mahjong tiles on the shuffling board are not exerted by any vertical pressure. The impact force collides with other mahjong tiles to generate loud noise; this greatly affects the player's experience. [0003] In order to eliminate these noises, the Chinese utility model patent with the publication number CN208193620U discloses a silent shuffling bucket for an automatic mah...
