Detailed Description

Referring to fig. 1, the stacking and pushing device in the figure comprises a stacking device and a pushing device, wherein the stacking device is used for stacking two mahjong tiles (not shown in the figure) into a pier, and the pushing device is used for pushing the pile of mahjong tiles stacked on the stacking device to a tile channel (in a conventional structure, the pile of mahjong tiles is not shown in the figure because the pushing stroke device 4 and the guide groove 41 are blocked to observe) to be stacked and arranged, so that the automatic arrangement of the mahjong tiles is realized.

Referring to fig. 2 in combination, the tile pushing device in the figure is a specific embodiment of the present invention, and specifically includes a tile pushing head 1, a tile pushing connecting rod 2, a power motor 3, and a tile pushing stroke device 4, wherein the tile pushing connecting rod 2 is provided with a tile pushing pin 21, the tile pushing stroke device 4 is provided with a guide groove 41, the tile pushing pin 21 is embedded in the guide groove 41 of the tile pushing stroke device 4 and can freely slide along the interior of the guide groove 41, the tile pushing head 1 and the tile pushing stroke device 4 are in transmission connection through the tile pushing connecting rod 2, the tile pushing head 1, the tile pushing connecting rod 2 and the tile pushing stroke device 4 together form a driven part driven by the power motor 3, the power motor 3 serves as a power mechanism for driving the tile pushing stroke device 4, and the effect of a cylindrical cam mechanism is utilized to drive the linearly guided and assembled tile pushing head 1 to reciprocate. The power motor 3 drives the mahjong pushing stroke device 4 to rotate, and the mahjong pushing pin 21 acts on the inner wall of the guide groove 41 to move back and forth, so that the mahjong pushing connecting rod 2 is pushed to drive the mahjong pushing head 1 to realize reciprocating linear motion. In order to reduce the wear of the card-pushing pin 21 in the guide groove 41, a rolling bearing which is in rolling contact with the inner wall of the guide groove 41 is provided on the card-pushing pin 21.

When the power motor 3 drives the tile pushing head 1 to contact and push the mahjong tiles, the tile pushing pin 21 of the tile pushing connecting rod 2 acts on the corresponding area of the inner wall of the guide groove 41 and is provided with an elastic buffer structure to eliminate the rigid collision effect of the tile pushing head 1 on the mahjong tiles. As shown in fig. 3, the elastic buffer structure of this embodiment includes an elastic avoiding space 43 disposed outside the side wall of the region of the guide groove 41 and gradually widening relative to the inner space of the guide groove, and a resilient sheet 42 separating the elastic avoiding space from the inner space of the guide groove, wherein one end of the resilient sheet 42 is elastically connected to the inner wall of the guide groove, and the other end thereof freely extends.

As shown in fig. 4, in the state where there is no external resistance, the elastic piece 42 ensures continuity of the inside of the guide groove 41, and the card push pin 21 of the card push link 2 freely moves in the guide groove without departing from the elastic buffer structure. When the tile pushing pin 21 of the tile pushing connecting rod 2 moves to contact with the elastic sheet 42 in the guide groove, the tile pushing head 1 contacts with the side face of the mahjong tile to be pushed, at the moment, the tile pushing pin 21 does not push the tile pushing connecting rod 2 along the inner wall of the guide groove 41, but pushes the tile pushing pin 21 and the tile pushing connecting rod 2 through the elastic sheet 42, because the tile pushing head 1 moves to contact with the mahjong tile, resistance is generated, at the moment, the acting force of the tile pushing pin 21 pushes the elastic sheet 42 to generate elastic deformation in the elastic avoiding space 43, as shown in fig. 5, the acting force of the tile pushing head 1 on the mahjong tile is gradually increased along with the gradual deformation of the elastic sheet 42, and the mahjong tile is pushed finally, but the mahjong tile is not pushed directly through rigid collision. The buffering action of the spring plate 42 reduces the impact noise generated by the direct rigid contact of the tile pushing head on the mahjong tiles.

The elastic piece 42 may be an elastic piece having elastic deformation, such as an elastic metal piece or an elastic nonmetal material piece, and the end portion is directly bent and embedded in the inner wall of the guide groove, and the elastic deformation of the elastic piece 42 itself is used to generate the buffer, or a rigid piece hinged and assembled to the inner wall of the guide groove by an elastic connecting member such as a torsion spring, such as a rigid metal piece or a rigid nonmetal material piece, and the elastic deformation of the elastic connecting member is used to generate the buffer.

Referring to fig. 1 again, the working process of the card pushing device and the card stacking device of the present embodiment is as follows: two mahjong tiles are sequentially stacked on the tile bearing seat 5 of the tile stacking device, the specific working principle of the tile stacking device is the prior art of the automatic mahjong machine, and reference can be made to a stacking and pushing mechanism of the mahjong machine disclosed in chinese patent publication No. CN202035696U, which is not described herein in detail in this embodiment. When the tile bearing seat 5 is aligned with a tile channel (in a conventional structure, the observation of the tile pushing stroke device 4 and the guide groove 41 can be blocked, so that the tile pushing stroke device is not marked in the drawing), the tile pushing head 1 moves towards the tile channel under the action of the power motor 3 driving the tile pushing stroke device 4 and the tile pushing connecting rod 2, a pile of mahjong tiles stacked on the tile bearing seat 5 are pushed onto the tile channel together, in the process that the tile pushing head 1 pushes the mahjong tiles, the impact noise of the tile pushing head 1 on the mahjong tiles is effectively reduced through elastic buffering by the elastic sheets arranged in the guide groove of the tile pushing stroke device 4, and meanwhile, the impact noise of the mahjong tiles on other mahjong tiles which are stored on the tile channel before is also effectively reduced through elastic buffering.

The tile pushing device of the invention can also adopt a gear rack mechanism, a screw rod mechanism, a shearing fork mechanism, a crank block mechanism or other cam mechanisms as power mechanisms for driving the tile pushing head to push the tiles to move in a reciprocating manner, and the above mechanisms are common driving mechanisms for outputting linear motion, and the specific structure and the working principle of the tile pushing device are not repeated in the embodiment.
