DETAILED DESCRIPTION

[0030] The present application will be further described in detail below in combination with the drawings and specific embodiments.

[0031] Example 1:

[0032] As Figures 1-8As shown, the mahjong machine pushing card machine head is arranged between the card feeding device 1 and the card storage channel 12, and includes a pushing card head 13 and a driving motor 14. The pushing card head 13 is connected with a translation seat 15. The translation seat 15 is connected with the driving motor 14 through a transmission mechanism 16. The pushing card head 13 is located on the axial extension line of the card storage channel 12 and can reciprocate along the card storage channel 12 under the driving of the driving motor 14. A card supporting mechanism is arranged between the card feeding device 1 and the card storage channel 12. The card supporting mechanism includes a base 3 and a card supporting seat 4 arranged above the base 3. The card supporting seat 4 is movably connected with the base 3 through a guide structure 8 in the vertical direction. A spring return assembly 6 is arranged between the card supporting seat 4 and the base 3. The height of the card supporting seat 4 in the weightless state is connected with the outlet of the card feeding device 1 to support the mahjong card. When the card supporting seat 4 supports one mahjong card, the card supporting seat 4 is compressed by the gravity of the mahjong card to make the card supporting seat 4 descend at least the height of the mahjong card. When the card supporting seat 4 supports two mahjong cards, the card supporting seat 4 is continuously compressed by the gravity of the two mahjong cards to make the card supporting seat 4 descend to the height connected with the card storage channel 12 to make the pushing card head 13 push the mahjong cards on the card supporting seat 4 into the card storage channel 12. A first limiting structure is arranged between the pushing card head 13 and the card supporting seat 4 to make the upper end of the card supporting seat 4 not exceed the lower end of the pushing card head 13 when the pushing card head 13 pushes the mahjong cards on the card supporting seat 4 into the card storage channel 12.

[0033] In the present embodiment, when the mahjong pushing head of the mahjong pushing machine is working, the mahjong tiles are sent to the tile receiving plate by the tile feeding device 1, the tile receiving seat 4 moves downward under the gravity of the mahjong tiles and compresses the elastic reset assembly 6, so as to sink at least the height of one mahjong tile, and then the second mahjong tile falls from the tile outlet of the tile feeding device 1 to the upper side of the first mahjong tile, while the two mahjong tiles are stacked, the tile receiving seat 4 sinks to the height of the connection with the tile storage channel 12 under the gravity of the two mahjong tiles and continues to compress the elastic reset assembly 6, at this time, the driving motor 14 drives the pushing head 13 to push the stacked mahjong tiles into the tile storage channel 12 through the transmission mechanism 16 and the translation seat 15, when the mahjong tiles on the tile receiving seat 4 are pushed away, the first limiting structure can still limit the upward movement of the tile receiving seat 4 until the pushing head 13 is reset, and then the tile receiving seat 4 is lifted again under the action of the compressed elastic reset assembly 6, waiting for the next round of tile receiving, when all the mahjong tiles are pushed into the tile storage channel 12, the tile feeding device 2 will feed the stacked mahjong tiles, compared with the prior art, the mahjong pushing head does not need external power to drive the tile receiving seat 4, simplifying the overall structure, and cooperating with the first limiting structure, the stacked mahjong tiles are pushed into the tile storage channel 12, and at the same time, the upper end of the tile receiving seat 4 is ensured not to exceed the lower end of the pushing head 13, avoiding the tile receiving seat 4 from being lifted too early, the reset track of the pushing head 13 is stuck, and the reset of the pushing head 13 is affected, as a supplement, the transmission principle and implementation of the transmission assembly 16 are both prior art, which will not be described here.

[0034] As preferred, as shown in Figure 7 and 8 , the first limiting structure includes a limiting part 17 arranged at the end of the pushing head 13 away from the pushing direction, and when the pushing head 13 pushes the mahjong tiles on the tile receiving seat 4 into the tile storage channel 12, the upper end of the tile receiving seat 4 directly presses the lower end of the limiting part 17 or the upper end of the tile receiving seat 4 presses the lower end of the limiting part 17 after being lifted.

[0035] In the present embodiment, the limiting part 17 is arranged at the end of the pushing head 13 away from the pushing direction, so that the limiting part 17 can limit the tile receiving seat 4 when the pushing head 13 pushes the stacked mahjong tiles into the tile storage channel 12.

[0036] As preferred, as shown in Figures 2-4 , the lower end of the limiting part 17 is flush with the lower end of the pushing head 13.

[0037] In the present embodiment, the lower end of the limiting part 17 is flush with the lower end of the pushing head 13, so that the limiting part 17 and the lower end of the pushing head 13 are smoothly transitioned, when the upper end of the tile receiving seat 4 abuts against the lower end of the limiting part 17 and the pushing head 13 is reset to the side away from the tile storage channel 12, the pushing head 13 passes above the tile receiving seat 4 more smoothly, realizing smooth transition.

[0038] As preferred, as shown in Figure 7 and 8 The limiting part 17 is plate-shaped, and the side of the limiting part 17 adjacent to the tile feeding device 1 is provided with a side plate 18 extending vertically upward and connected with the tile pushing head 13.

[0039] In the embodiment, when the tile pushing head 13 pushes the stacked mahjong tiles on the tile receiving seat 4 into the tile storage channel 12, the vertically upward side plate 18 can block the tile outlet of the tile feeding device 1, preventing the mahjong tiles from falling on the tile receiving seat 4 which has not been completely reset. The side plate 18 is connected with the tile pushing head 13, which enhances the structural strength of the side plate 18 and prolongs the service life of the side plate 18.

[0040] Example 2:

[0041] As shown in Figure 5 and 6 The difference between the present embodiment and example 1 is that the guiding structure 8 includes at least one guiding rod 9 arranged on the tile receiving seat 4 and at least one guiding hole 10 arranged on the base 3, and the guiding rod 9 is slidably connected with the guiding hole 10 one by one.

[0042] In the embodiment, the bottom of the tile receiving seat 4 is provided with the guiding rod 9 which is slidably arranged in the guiding hole 10. When the tile receiving seat 4 sinks to receive the mahjong tiles or rises under the action of the elastic reset assembly 6, the guiding rod 9 will descend or rise along the guiding hole 10, thereby guiding the descending or rising movement of the tile receiving seat 4, avoiding the position deviation of the tile receiving seat 4 in the repeated rising and sinking process, and ensuring the stability of the tile receiving seat 4 when receiving the mahjong tiles.

[0043] As preferred, as shown in Figure 5 and 6 The number of the guiding rod 9 and the corresponding guiding hole 10 is not less than two; or the guiding rod 9 and the corresponding guiding hole 10 are non-circular, and the guiding rod 9 is matched with the guiding column.

[0044] In the embodiment, at least two guiding rods 9 and corresponding guiding holes 10 are arranged. Compared with a single number of guiding rods 9, the guiding rods 9 and the corresponding guiding holes 10 can effectively prevent the tile receiving seat 4 from rotating circumferentially along the guiding rod 9, and the guiding stability is better. Arranging the two as non-circular can also effectively prevent the tile receiving seat 4 from rotating circumferentially along the guiding rod 9, and improve the stability.

[0045] As preferred, as shown in Figure 5 and 6 The elastic reset assembly 6 includes a spring 7, the upper end of the spring 7 acts on the tile receiving seat 4, and the lower end acts on the base 3; the number of the spring 7 is the same as the number of the guiding rod 9 and is arranged one by one, and the spring 7 is sleeved on the corresponding guiding rod 9.

[0046] In the embodiment, the spring 7 can be a common commercially available product, and the number of the spring 7 corresponds to the guide rod 9, and the spring 7 is sleeved on the outer side of the guide rod 9. When the spring 7 provides elastic potential energy for the tile holder 4 to reset, the tile holder 4 is uniformly stressed and is not easy to be deflected or tilted.

[0047] As preferred, as shown in Figure 5 and 6 , the guide hole 10 is provided with an annular step 11, and the lower end of the spring 7 enters the guide hole 10 and acts on the annular step 11. When the tile holder 4 is lowered to the height of the tile storage channel 12, the spring 7 as a whole enters the guide hole 10, and the lower end of the tile holder 4 acts on the top of the base 3.

[0048] In the embodiment, the annular step 11 is arranged in the guide hole 10, which is used for installing the spring 7 and limiting the spring 7, and can also avoid excessive pressure on the spring 7 to cause irreversible deformation of the spring 7 and affect the rebound effect. When the tile holder 4 is lowered to the height of the tile storage channel 12, the spring 7 as a whole enters the guide hole 10, and the lower end of the tile holder 4 acts on the top of the base 3. The lower end of the tile holder 4 is attached to the top of the base 3, that is, the tile holder 4 is lowered to the lowest position. Before the mahjong tiles are pushed into the tile storage channel 12 by the tile pushing head 13, the tile holder 4 cannot move in the vertical direction under the gravity of the mahjong tiles, which further increases the stability of the mahjong tiles pushed into the tile storage channel 12.

[0049] As preferred, as shown in Figure 5 and 6 , the tile holder 4 is provided with a magnetic body that can be magnetically connected with the mahjong tiles; the tile holder 4 is provided with a mounting groove 5, and the magnetic body is embedded in the mounting groove 5.

[0050] In the embodiment, the mounting groove 5 for mounting the magnetic body is arranged on the tile holder 4, and the magnetic body is used to magnetically attract the received mahjong tiles, thereby improving the stability of the received mahjong tiles and the stacking of the mahjong tiles.

[0051] As preferred, the second limiting structure is arranged between the guide rod 9 and the base 3 to prevent the guide rod 9 from being axially separated from the guide hole 10.

[0052] In the embodiment, the second limiting structure can limit the position of the guide rod 9 to prevent the guide rod 9 from being excessively moved upward and separated from the guide hole 10. In addition, the limiting structure can be a prior art structure such as a limiting buckle or a limiting clamping protrusion.
