The existing mahjong machine is set as follows: in the process that the tile pusher head pushes the tile pier away from the tile bearing table, the tile blocking piece is required to block the mahjong tiles to be sent into the tile bearing table; after the tile pushing machine head finishes one-time tile pushing action and returns to the original position, the tile blocking piece is removed so that the mahjong tiles enter the tile bearing table to be piled up, and the tile pushing machine head is in a waiting state in the tile stacking process; after the mahjong pieces are piled up, the mahjong piece pushing machine head is started again to push the mahjong pieces.
The invention discloses a mahjong machine and a tile pushing machine head thereof, wherein the tile pushing machine head comprises a machine head box and at least one tile pushing motor arranged on the machine head box, and a first tile pushing position and a second tile pushing position which are arranged back and forth along the mahjong conveying direction are formed on the machine head box; the machine head box is also provided with a first card pushing head and a second card pushing head, wherein the first card pushing head is positioned at one side of the first card pushing position and is driven by a card pushing motor to horizontally slide relative to the machine head box to enter and exit the first card pushing position so as to push cards, and the second card pushing head is positioned at one side of the second card pushing position and is driven by the card pushing motor to horizontally slide relative to the machine head box to enter and exit the second card pushing position so as to push cards; the machine head box is also provided with a blocking block, and the blocking block is positioned between the first tile pushing position and the second tile pushing position and is driven by the tile pushing motor to lift up and down relative to the machine head box so as to block mahjong tiles and provide mahjong tiles for passing.
As another example, chinese patent publication No. CN10962293a discloses a stacking and pushing mechanism of a mahjong machine, where the stacking and pushing mechanism includes a tile supporting table at a tile outlet of the tile taking and conveying mechanism, a tile pushing head is slidably disposed above the tile supporting table, a tile pushing start site of the tile pushing head is located at a side of the tile supporting table and adjacent to a tile outlet of the tile taking and conveying mechanism, and a tile storing track opposite to the tile pushing start site of the tile pushing head is also disposed at a side of the tile supporting table; the card pushing head is provided with repeated card pushing positions for pushing the card piers on the card bearing table into the card storage track one by one and card feeding positions for pushing all the card piers in the card storage track onto the card lifting card bearing plate; and the card pushing head is also provided with a card blocking part facing the card outlet of the card taking and conveying mechanism.
The card pushing machine head has the following defects: (1) Card stacking action cannot be performed in the card stacking process, so that after one card stacking action is completed, the card stacking head needs to return to the original position and can be used for pushing cards again after the card stacking action is completed, the time required for one card stacking is long, the card stacking efficiency is low, and the upstream card stacking efficiency and the downstream card feeding efficiency are low; (2) In order to shorten the tile pushing time, a motor with higher rotating speed and higher power is required to drive the tile pushing head so as to accelerate the running speed of the tile pushing head, so that the motor is higher in requirement, and the tile pushing head can quickly strike the mahjong tiles, so that the tile pushing noise is quite high.
Disclosure of Invention
The invention aims to provide a mahjong machine tile pushing machine head, which has high tile pushing efficiency, does not influence tile pushing actions and tile stacking actions, has lower requirements on the performance of a tile pushing motor, and greatly reduces tile pushing noise.

According to the invention, the card pushing head is arranged on the card pushing head carrier which is connected end to end and can circumferentially rotate, and driven by the card pushing motor, the card pushing head passes through the card pushing site in a reciprocating manner along the circumference of the card pushing head carrier, the card pushing head thoroughly abandons the running mode that the existing card pushing head returns along the original path after pushing the cards, the card pushing head does not return along the original path after pushing the card pier at the card pushing site, but returns to the card pushing site along an annular path along with the card pushing head carrier, so that the normal running of card stacking action is not affected no matter the card pushing head forwards or returns to the origin, the card stacking action can be performed without waiting for the card pushing head to return to the origin, and a new round of card stacking can be performed only by pushing the card pier by the card pushing head, so that the purposes of quick card stacking and quick card pushing are realized, and the card stacking efficiency and the downstream card stacking efficiency are improved at one step.
Because the card pushing head returns to the card pushing position and is synchronously carried out with the card stacking, the card pushing head waiting time is omitted, and when the card pushing motor with the same performance (including rotating speed, power and the like) as the card pushing motor in the prior art is adopted to drive the card pushing head, the card pushing efficiency of the card pushing head is higher; when the invention keeps the traditional tile pushing efficiency, the tile pushing motor with lower performance can be adopted, and the noise generated by the tile pushing head impacting the mahjong tile is smaller when the tile is pushed.

as shown in fig. 9 and 7, each card pushing part 6b is further provided with a detection point 8 (a magnet adopted in this embodiment), the card pushing box 3 is further provided with a detector 9 (a hall switch adopted in this embodiment) positioned on the movement path of the card pushing part 6b, the detector 9 is connected with a control unit, the detector 9 is used for detecting the number of times that the detection point 8 passes through the detector 9, and each time the detector 9 detects the detection point 8, the card pushing head 6 finishes one card pushing, and the control unit is used for receiving an output signal of the detector 9 and controlling the start and stop of the card pushing motor 2 according to the output signal, and when the card pushing number reaches a preset value, the control unit closes the card pushing motor 2 to complete the whole card pushing program.
Example 2
The tile pushing head of the mahjong machine is basically the same as the tile pushing head of the embodiment 1, and the only difference is that: only one card pusher 6 is provided on the card pusher carrier 4.
