Description

Technical Field

[0001] The utility model relates to the technical field of mahjong machines, in particular to a card loading mechanism and a mahjong machine that is not prone to card jams. Background Art

[0002] Mahjong machines, a leading modern entertainment device, have made a splash in the mahjong world thanks to their automation and efficiency. Their operating principle cleverly combines the properties of electromagnets and magnetism, bringing unprecedented convenience and enjoyment to players. The back of the tiles contains a magnetically attractive material, while the front does not. The tiles rotate on a tilted disc. When the tiles reach a high point, the back-facing tiles are attracted by the magnetic rings on the shuffling drum. As the magnetic rings rotate, they are transported to a conveyor chute, where they are stacked by a stacking motor and then pushed away by a chain rod. To reduce the size of mahjong machines, the lifting mechanism has been replaced by a rotary mechanism, and more and more mahjong machines are adopting this mechanism.

[0003] Chinese invention patent publication number CN107773976A, issued on March 9, 2018, discloses a circular card-pushing device for an automatic mahjong machine and the machine itself. This invention addresses the issues of existing mahjong machines, such as the large size and complex structure. The circular card-pushing device comprises a motor, a base, a turntable, and a card-pushing block. The motor is mounted on the base, which is provided with a circular card-pushing trough with a card inlet and a card outlet. The turntable is located above the base and is driven to rotate by the motor. The turntable drives the card-pushing block to push cards within the circular card-pushing trough. The use of a rotating card-pushing method reduces the space required to push mahjong tiles.

[0004] However, mahjong tiles are becoming larger and heavier, and are easily stuck during circular transportation. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a card loading mechanism and a mahjong machine that are not easily jammed. The present invention aims to solve the technical problem in the prior art that mahjong tiles are easily jammed when being transported in an annular manner.

[0006] To achieve the above-mentioned purpose, the utility model proposes a card loading mechanism that is not easy to get stuck, comprising a card loading shell and a card track arranged in a ring shape on the card loading shell, wherein the card track is used to transport mahjong; a magnet is arranged at the bottom of the card track, and the mahjong has a magnetic strip inside. When the mahjong is in the card track, the magnet and the magnetic strip repel each other.

[0007] Preferably, the mahjong track is provided with an entrance and an exit, and mahjong enters the mahjong track from the entrance and leaves the mahjong track from the exit.

[0008] Preferably, an annular groove is provided on the card track, and the magnets are distributed along the annular groove.

[0009] Preferably, a rotating seat is provided on the card-loading housing, a disk-pushing rod is provided on the rotating seat, and a disk-pushing head is provided on the disk-pushing rod. The disk-pushing head can move on the card path and can push mahjong.

[0010] Preferably, the card path includes an inner wall and an outer wall, the inner wall is the side close to the center of the card loading shell, and the outer wall is the side away from the center of the card loading shell; the ratio of the pushing head to the inner wall and the outer wall is 1:4~1:2.

[0011] Preferably, a protrusion is provided at the lower end of the pushing head, and the protrusion extends in the direction of pushing the mahjong. The height of the protrusion gradually decreases along the extending direction.

[0012] To achieve the above object, the utility model provides a mahjong machine, which uses the above-mentioned card loading mechanism.

[0013] Compared with the prior art, the present invention provides a card loading mechanism and a mahjong machine that is not prone to card jamming, which have the following beneficial effects:

[0014] Mahjong enthusiasts are increasingly favoring larger tiles, which are easier to see. However, larger tiles also weigh more, and greater weight creates greater friction. The circular tile path, meanwhile, involves rotating tiles, and the force required to push them varies constantly. This force can be insufficient, necessitating a higher-power motor. However, the addition of magnets, which repel the magnetic strips of the tiles, reduces the pressure of the tiles on the tile path and the friction generated. This reduces the motor's ability to push the tiles, making it less prone to burnout.

[0024] The present invention provides a mahjong machine having a card loading mechanism that is not easy to jam the tiles. The card loading mechanism prevents the tiles from getting stuck during the loading process. The card loading mechanism is described in detail below.

[0025] See Figure 1In an optional embodiment, a card loading mechanism that is not easily jammed includes a card loading housing 1 and a card track 2 arranged in a ring shape on the card loading housing 1, wherein the card track 2 is used to transport mahjong tiles; a magnet 3 is provided at the bottom of the card track 2, and the mahjong tiles have a magnetic strip inside. When the mahjong tiles are in the card track 2, the magnet 3 and the magnetic strip repel each other. A card loading mechanism is provided at each of the four corners of the mahjong machine. The magnet 3 on the card track 2 and the mahjong tiles being transported are in a state of mutual repulsion, reducing the pressure of the mahjong tiles on the bottom surface of the card track 2, thereby reducing friction. A motor of the same power can transport heavier mahjong tiles, thereby extending the service life of the motor.

[0026] See Figure 1-2 In an optional embodiment, the loading housing 1 is provided with a rotating base 4, which is provided with a push rod 5. The push rod 5 is provided with a push head 7. The push head 7 is movable along the tile path 2 and can push the tiles. The rotating base 4 is fixed at the center of the loading housing 1. A motor is fixed at the center of the rotating base 4. The motor drives the push rod 5 to rotate around the center of the rotating base 4. The push head 7 rotates with the push rod 5, pushing the tiles to load the tiles.

[0027] In an alternative embodiment, the mahjong track 2 is provided with an entrance 21 and an exit 22. Mahjong tiles enter the track 2 from the entrance 21 and exit the track 2 from the exit 22. Mahjong tiles are stacked one on top of the other and enter the track 2 from the entrance 21 until all the tiles are stacked in the track 2. The drive motor of the push rod 5 is activated, causing the push head 7 to push the mahjong tiles out of the exit 22 and onto the table.

[0028] See Figure 1 In an optional embodiment, the mahjong track 2 is provided with an annular groove 25, along which the magnets 3 are distributed. The annular groove 25 is located at the bottom of the mahjong track 2, reducing the contact area between the mahjong pieces and the bottom of the track 2, thereby reducing friction. Furthermore, without a base separating the mahjong pieces from the magnets 3, the mutual repulsion between them is stronger, further reducing friction.

[0029] At the same time, the magnets can be arranged along the annular groove as a whole, or a magnet block can be placed at intervals in the annular groove. Both of these methods belong to the structure distributed along the annular groove 25.

[0030] See Figure 1In an optional embodiment, the mahjong track 2 includes an inner sidewall 23 and an outer sidewall 24, wherein the inner sidewall 23 is located closer to the center of the card loading housing 1, and the outer sidewall 24 is located farther from the center of the card loading housing 1. The ratio of the distance between the pusher head 7 and the inner sidewall 23 and the outer sidewall 24 is 1:4 to 1:2. Preferably, the ratio of the distance between the pusher head 7 and the inner sidewall 23 to the distance between the pusher head 7 and the outer sidewall 24 is 1:3. Because the mahjong is loaded in a rotating manner, the pusher head 7 is not able to directly push the center of the mahjong. If it is in the center, the center of the mahjong will easily shift during movement along the circular mahjong track 2, and the mahjong will easily become stuck on the track. The ratio of the distance between the pusher head 7 and the bottom of the mahjong track to the depth of the track is 1:10 to 1:5, with a preferred ratio of 1:6. If the mahjong is stacked in two, excessive thrust will cause the mahjong to tilt and become stuck, and will also cause the upper and lower mahjong pieces to separate.

[0031] See Figure 1 In an optional embodiment, a protrusion 71 is provided at the lower end of the pusher head 7. The protrusion 71 extends in the direction of pushing the tiles, and the height of the protrusion 71 gradually decreases along the extension direction. The contact area between the pusher head 7 and the tiles cannot be too large. If it is too large, the tiles will not be pushed flexibly, and the tiles will be tilted due to the limit and cannot be adjusted and stuck in the tile path 2.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
