The same stop mechanism may also be provided for the first pusher head 22 to secure the first pusher head 22 in the rest position.
Because both ends of the first traction rope 30 are fixed on the first card pushing reel 25, the first traction rope 30 can be driven to move along the first guide groove 18a when the first card pushing reel 25 rotates and can be released and retracted; and the first pusher 22 fixedly mounted to the first traction rope 30 moves therewith.
As shown in fig. 1, taking the case that the big tray 2 has four directions of east E, south S, west W and north N as an example, for the eastern direction of the big tray 2, since the card feeding end of the first card feeding track 5 is connected with the first card lifting and supporting board 3 positioned in the eastern direction of the big tray 2 by the first card pushing reel 25 positioned below the first card lifting and supporting board 3, the initial card feeding track 17 is positioned in the southern direction of the big tray 2, and the first card pushing reel 25 positioned in the southern direction of the big tray 2 is positioned in the bending region of the first card feeding track 5 positioned in the eastern direction of the arc-shaped curved big tray 2. Since the first traction rope 30 needs to slide in the first guiding groove 18a, in order to ensure the fitting degree of the first traction rope 30 and the first guiding groove 18a, in this embodiment, the first traction rope 30 is pulled by the first card pushing reel 25 located in the bending area of the first card feeding track 5, rather than the first card pushing reel 25 located at the card feeding end of the first card feeding track 5. The second traction rope 31 operates in the same principle as the first traction rope 30.
Since the first traction rope 30 is the second traction rope 31 which is pulled by the first card pushing reel 25 in the bending area of the first card feeding rail 5, the first traction rope 30 needs to be rotated to the rear sides of the first card feeding rail 5 and the initial card feeding rail 17 at the end of the card feeding of the first card feeding rail 5 and the initial card feeding rail 17; under the traction of the first card pushing reel 25, the first traction rope 30 generates a large friction with the first card feeding rail 5 and the initial card feeding rail 17. In order to eliminate the friction, as shown in fig. 4 and 8, in this embodiment, at both ends of the first distance-adjusting strip 18, a first steering wheel 28 is rotatably installed on the frame 1 to facilitate steering of the first traction rope 30 and adjust the running speed of the first traction rope 30; a second steering wheel 29 which is convenient for the second traction rope 31 to steer and adjust the running speed of the second traction rope 31 is rotatably arranged on the frame 1 at two ends of the second distance-adjusting strip 20; the first steering wheel 28 and the second steering wheel 29 can assist the first traction rope 30 and the second traction rope 31 to smoothly steer without any excessive friction with the first distance-adjusting strip 18; in addition, since the lengths of the first distance-adjusting strip 18 and the second distance-adjusting strip 20 are different, the running speeds of the first card pushing head 22 and the second card pushing head 23, namely the first traction rope 30 and the second traction rope 31, can be controlled by adjusting the outer diameters of the first steering wheel 28 and the second steering wheel 29, so that the two can reach the card sending end synchronously. Specifically, since the second card feed rail 6 is located inside the first card feed rail 5, the length of the second gauge strip 20 is longer than the length of the first gauge strip 18, and therefore the outer diameter of the second diverting wheel 29 needs to be set larger than the outer diameter of the first diverting wheel 28.
Before the tile is sent, the stacking mechanism stacks three layers of mahjong tiles in the initial tile sending track 17, the first tile pushing head 22 and the second tile pushing head 23 are both positioned at the initial end of the initial tile sending track 17, and the second tile pushing head 23 and the first tile pushing head 22 are magnetically attracted and fixed on the first limiting seat 33.
The working principle of the tile lifting and bearing mechanism of the roller coaster type eight-port full-automatic mahjong machine is as follows: when the mahjong pieces are required to be pushed onto the first lifting tile supporting plate 3 and the second lifting tile supporting plate 4, the driving gear 13 is driven by the motor 12 to rotate anticlockwise, at this time, the driving shaft 14f is positioned at the bottom end of the start-stop groove 13b (as shown in fig. 4), and the bottom end of the start-stop groove 13b pushes the driving shaft 14f, so that the cam 14 rotates along with the driving gear 13, and the push travel curved surface 14c, the far rest curved surface 14d and the return travel curved surface 14e sequentially reach the transmission plate 15: when the pushing curve surface 14c rotates to the transmission plate 15, the side wall of the pushing curve surface 14c presses the second driven roller 15a and pushes the transmission plate 15, so that the transmission plate 15 and the linkage rod 9 synchronously displace horizontally, and the end part of the linkage rod 9 slides into the guide chute 11 from the vertical groove 10 to drive the free ends of the first card lifting and carrying plate 3 and the second card lifting and carrying plate 4 to turn down; when the far rest curved surface 14d rotates to the transmission plate 15, only the second driven roller 15a is in rolling fit with the far rest curved surface 14d, and the far rest curved surface 14d does not push and pull the second driven roller 15a, so that the transmission plate 15 is kept stationary and does not horizontally shift, and the free ends of the first card lifting and carrying plate 3 and the second card lifting and carrying plate 4 are kept in a downward turning state; the non-toothed portion 14h of the drive gear 13 then also reaches the transmission plate 15 side, and the toothed portion 14g reaches the reel gear 27 side, meshing with the reel gear 27, which achieves: when the free ends of the first rising card bearing plate 3 and the second rising card bearing plate 4 keep a downward turning state, the driving gear 13 can drive the reel gear 27 to drive the first card pushing reel 25 and the second card pushing reel 26 to rotate, and the first card pushing head 22 and the second card pushing head 23 are driven by the first traction rope 30 and the second traction rope 31 to realize card pushing action, so that mahjong tiles are continuously sent to the first rising card bearing plate 3 and the second rising card bearing plate 4; when the first card pushing head 22 and the second card pushing head 23 reach the card sending end of the first card sending track 5 and the second card sending track 6 respectively, the toothed part 14g of the driving gear 13 is not meshed with the reel gear 27 any more, the toothless part 14h rotates to the side of the reel gear 27, the return curve surface 14e rotates to the transmission plate 15, the side wall of the return curve surface 14e pulls the transmission plate 15, so that the transmission plate 15 and the linkage rod 9 synchronously shift horizontally, the end part of the linkage rod 9 returns to the vertical groove 10 from the guide chute 11, the free ends of the first card lifting card bearing plate 3 and the second card lifting card bearing plate 4 are driven to be turned upwards at the same time, the initial state of being flush with an outlet is returned, and the card lifting is ended; at this time, the reel gear 27 is at the midpoint of the toothless portion 14h of the drive gear 13 (i.e., the engagement time of the reel gear 27 with the toothless portion 14h is the same as the rolling engagement time of the second driven roller 15a with the return curved surface 14e and the push curved surface 14 c). After the rising of the mahjong tiles is finished, a row of mahjong tiles are held on the first rising tile carrying plate 3, and two rows of mahjong tiles are held on the second rising tile carrying plate 4, so that people can immediately start playing the mahjong tiles without dealing and cutting the mahjong tiles; at this time, the second card pushing head 23 is magnetically fixed on the second limiting seat 34.
When people play cards, the driving gear 13 rotates clockwise for one circle (the bottom of the driving gear 13 is provided with a magnetic control site 35 for monitoring the rotation angle of the driving gear 13), in the rotating process, the driving shaft 14f of the cam 14 ascends along the bottom surface of the start-stop groove 13b, no pushing point exists between the driving shaft 14f and the start-stop groove 13b, the cam 14 is static and does not rotate, and after one circle of rotation is finished, the driving shaft 14f falls into the bottom end of the start-stop groove 13b again and waits for card lifting again.
And the toothed portion 14g of the driving gear 13 is meshed with the reel gear 27 again to drive the reel gear 27, the first card pushing reel 25 and the second card pushing reel 26 to reversely rotate, and the first card pushing head 22 and the second card pushing head 23 are returned to the starting end of the initial card feeding track 17 by pulling the first traction rope 30 and the second traction rope 31 to wait for the card to be fed again.
