Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of mahjong machine pushing equipment, and particularly relates to a double-rod tile feeding device of a small-arc pushing groove of a mahjong machine. BACKGROUND

[0002] At present, mahjong machines only adopt linear or disc type pushing groove structures. The tile feeding system of the linear pushing groove structure is complex, occupies a large amount of machine space position, different tile types need different model and specification tile feeding systems, and there are many problems such as large upgrade investment, complex assembly and production, and inconvenient after-sales maintenance. The disc type pushing groove structure is simplified in structure, but due to the limitation of the overall structure of the machine body, the pushing groove can only be arranged at the four corners of the machine body. Therefore, the size of the pushing groove is seriously limited by the size of the machine table, and the size of the pushing groove determines the size of the available tile type. Therefore, the disc type pushing groove structure is limited by the size of the machine table in terms of tile type selection. In order to make large tile types, a large table must be used to realize it. In addition, since the arc of the pushing groove is much larger than 180 degrees, the pushing resistance is large, and the four corners are occupied by the pushing groove, and the size of the middle tile washing barrel is limited, thereby increasing the risk of card jamming, motor circuit damage due to high load, and heat damage of the entire machine structure.

[0003] In order to solve the problems in the prior art, people have carried out long-term exploration and proposed various solutions. For example, Chinese patent documents disclose a mahjong machine and a tile pushing system thereof [201610734435.8]. The tile feeding assembly includes a tile feeding support, a tile storage groove, a first tile feeding push head and a second tile feeding push head are arranged on the tile feeding support, a notch is formed in the inner side wall of the middle position of the tile storage groove, the tile storage groove is communicated with the reversing groove through the notch, the first tile feeding push head is driven by the tile feeding driving mechanism to move from the tile feeding port of the tile storage groove to the vicinity of the notch and then return, the second tile feeding push head is driven by the tile feeding driving mechanism to move from the tile feeding port of the tile storage groove to the reversing groove and then return, the tile feeding driving mechanism includes a first tile feeding push rod and a second tile feeding push rod which reciprocate and cooperate with each other, the first tile feeding push head is arranged on the first tile feeding push rod, and the second tile feeding push head is arranged on the second tile feeding push rod.

[0004] The above-mentioned scheme solves the problems caused by the structure of the existing mahjong machine to some extent, but the scheme still has many deficiencies, such as the dependence on complex transmission parts such as gears and cams leads to the increase of manufacturing cost, the lack of coordination between the double-rod actions and the difficulty in synchronous control.

Through the linkage design of the tile pushing disc body 12, the tile pushing rod 14 and the tile pushing seat 2, the two tile pushing rods 14 alternately push the tile pushing seat 2, avoiding the intermittent pause of the traditional single-rod tile pushing, improving the tile pushing efficiency and continuity, the double-rod tile pushing structure 3 realizes automatic tile pushing through mechanical transmission, reduces manual intervention, conforms to the design trend of intelligentization and mechanization of mahjong machines, and the guide groove set 13 cooperates with the tile pushing seat 2 to ensure that the tile pushing seat 2 slides along the fixed track, avoiding shaking or deviation, improving the stability and precision of the tile pushing action, and reducing the risk of card jamming.

A blocking block 39 is arranged at the second opening 38. The curved tracks in the first pushing groove 26 and the second pushing groove 27 cooperate with the pushing shafts, and the pushing shafts slide along the curved tracks driven by the rotation of the pushing disc body 12, thereby realizing the reciprocating movement of the pushing seat 2. The action logic is clear, and collision is avoided. Meanwhile, the first opening 35 and the second opening 38 are provided for the pushing shafts to slide in, and the blocking block 39 can prevent the pushing shafts from accidentally coming out when the pushing seat 2 starts to reset, thereby ensuring the reliability and safety of power transmission during double-rod pushing.

[0045] In combination Figure 1 , Figure 3 and Figure 4As shown, the tile pushing switching assembly 4 includes a tile pushing track 41 and a reset track 42 arranged on the tile storage rack body 1 and in communication with each other, the first tile pushing shaft 33 slides through the tile pushing track 41 or the reset track 42, and the second tile pushing shaft 36 slides through the tile pushing track 41 or the reset track 42.

[0047] As shown in combination with Figure 2 , Figure 11 and Figure 12 , one end of the first arc-shaped through slot 17 close to the tile in end of the tile pushing groove 11 is bent towards the inner guide frame 16 to form a tile pushing shaft initial slot 5 for placing the first tile pushing shaft 33, the tile pushing lifting frame 51 is movably arranged at the lower end of the tile storage rack body 1 and below one end of the inner guide frame 16, one end of the tile pushing lifting frame 51 is hingedly arranged on the tile storage rack body 1 and the other end has a vertical movement and is arranged in the inner guide slot 161 close to the tile in end of the tile pushing groove 11, and the lower side of the tile pushing lifting frame 51 abuts against the outer side of the first tile pushing rod body 141.

The inner guide shaft 22 of the pusher seat 2 slides in the inner guide groove 161 and the outer guide shaft 24 slides in the outer guide groove 151 to realize double guiding, ensuring stable sliding along the arc track of the pusher groove 11. The inner guide part 23 and the outer guide part 25 slide with the inner guide bracket 16 and the outer guide bracket 15 respectively, further limiting the movement direction of the pusher seat 2 to avoid deviation. The first pusher shaft 33 is located in the pusher shaft initial groove 5, the second pusher shaft 36 is in the reset track 42, the first pusher rod body 141 and the second pusher rod body 142 rotate with the disc body, the first pusher shaft 33 slides from the pusher shaft initial groove 5 into the pusher track 41, at the same time, the first pusher shaft 33 enters the first pusher groove 26 of the pusher seat 2 through the first opening 35 and slides along the first curve track 34 in the first pusher groove 26. The shape of the curve track forces the pusher seat 2 to slide along the guide groove group 13 to the card end, and the pusher part 21 pushes the mahjong tiles in the pusher groove 11 from the card end to the card end. When the first pusher shaft 33 moves to the middle of the pusher track 41, the second pusher shaft 36 moves from the reset track 42 to the pusher track 41. When the first pusher shaft 33 leaves the pusher track 41 and enters the reset track 42, the first pusher shaft 33 moves out from the first opening 35 and separates from the pusher seat 2, at the same time, the second pusher shaft 36 enters the second pusher groove 27 from the second opening 38 to continue to push the pusher seat 2 to move towards the card end. When the pusher seat 2 starts to reset, the pusher disc body 12 starts to rotate, the first pusher rod body 141 and the second pusher rod body 142 continue to rotate with the disc body, the second pusher shaft 36 contacts the blocking block 39 and drags the pusher seat 2 to move. In the dragging process, the first pusher shaft 33 enters the first pusher groove 26 from the first opening 35. When the first pusher shaft 33 completely enters the first pusher groove 26, the second pusher shaft 36 is separated from the blocking block 39 and moves out of the second pusher groove 27 from the second opening 38. Then the first pusher shaft 33 continues to drag the pusher seat 2 to move towards the card end. When the pusher seat 2 moves to the card end, the first pusher shaft 33 moves out from the first opening 35 and enters the pusher shaft initial groove 5, thereby realizing the continuous action of double-rod alternating pusher and reset.
