The upper end of the electric mahjong table is connected with a top cover 13 through a quick release part. 2. A card sorting board 8 is provided on the peripheral surface near the card pushing mechanism 4.

The present application provides a whole machine structure of a new type of fully automatic electric mahjong table. The shuffling bucket 1 performs a flower-shuffling operation on the mahjong tiles. After the shuffling, the conveying mechanism 3 sucks the mahjong tiles out of the shuffling bucket 1 and transfers them to the storage one by one. At the card entrance of the card track slot 7, the card pushing mechanism 4 organizes the mahjong tiles into piers. The upper plate, the transition plate and the lower plate, the transition plate is an arc-shaped plate, the distance between the upper plate and the outer peripheral surface of the card storage tray 2 is greater than the distance between the lower plate and the outer peripheral surface of the card storage tray 2, and the card management plate 8 The side away from the card pushing mechanism 4 is provided with a light control sensor, the card management board 8 is provided with a through hole that allows the light control sensor to carry out signal interaction, and the mahjong tiles are formed on the card holder 46 of the card pushing mechanism 4.

When the magnetic control sensor on the card pushing mechanism 4 senses the induction magnet, the motor of the card pushing mechanism 4 stops working. The card pushing action is completed, and then the upper card transmission mechanism 5 pushes the mahjong tiles from the card inlet to the upper card bar 61 through the card outlet. ) flush, the mahjong tile is lifted to the table top; in this application, the top cover (main cover 14) is fixed by a quick-release part, and the quick-release part can be a connector with a quick-release function such as a buckle. The cover (main body cover 14) is very convenient to detach and assemble.

The card storage tray 2 of the present creation also includes a card storage tray housing, and a card storage tray housing is installed with a card push rod 9 that can move circumferentially in the card storage track slot 7, and the card storage track slot 7 includes an upper rail The road 71 and the lower track 72, two mahjong tiles stacked up and down at the same position, the mahjong tile located on the upper track 71, when pushed to the outlet by the card pusher 9, the length of the path passed is greater than the length of the path on the lower track. The length of the path traveled by the 72 mahjong tile when it is pushed to the exit by the pusher rod 9.

The mahjong tiles are divided into upper and lower layers in the card storage track slot 7. The number of mahjong tiles on the upper and lower layers is the same. The two adjacent mahjong tiles on each layer are close to each other to form a mahjong tile queue, and the push lever 9 pushes the mahjong tiles. On the last two mahjong tiles, when the push lever 9 pushes the last two mahjong tiles, each mahjong tile provides thrust to the mahjong tile located on its front side, when the first mahjong tile is pushed out from the upper track, The rear section of the pair of mahjong tiles is still located in the card storage track slot 7, because "two mahjong tiles stacked up and down at the same level position, the mahjong tile located in the upper track 71 is pushed to the outlet by the card push rod 9. The length of the path traversed is greater than the path length” of the mahjong tiles located on the lower track 72 when they are pushed to the exit by the push lever 9, and the distance from the last mahjong tile in the upper mahjong tiles to the outlet is greater than that of the lower mahjong tiles. The distance from the last mahjong tile to the outlet, and because the adjacent mahjong tiles are in close proximity to each other, so among the two mahjong tiles at the front of the pair of mahjong tiles, the position of the mahjong on the upper layer is relative to that of the mahjong on the lower layer. The position is a little later, so it is not easy to slip off during the process of being pushed out, and it is not easy for the phenomenon of "down card" to occur.

The shape of the card storage track slot 7 is a square with an arc at the corner; the arc part in the card storage track slot 7 can make the mahjong tiles more gentle when the movement direction is changed, and it is not easy to be stuck, effectively reducing the motor running. The load torque in the middle of the motor reduces the damage and failure rate of the motor, and improves the service life of the motor, and the straight part in the card storage track slot 7 can increase the contact area of two adjacent mahjong tiles, and reduce the generation of mahjong tiles in the process of pushing back and forth. In the prior art, part of the card storage track groove 7 is a circular ring, and the ring-shaped electric mahjong table is in a state of continuous turning after the mahjong tile enters the track because the mahjong tile is in the promotion process, thereby causing the mahjong tile to advance in the sliding process. In the middle of the motor, they have been changing their respective angles and squeezing each other, forming a great resistance, which will also cause the motor to be damaged frequently due to the heavy load during operation.

Since the shape of the card storage track slot 7 is a square with arcs at the four corners, the distances from each point on the trajectory line of the card storage track slot 7 to the center of the card push turntable are not the same. Always push the mahjong tiles at the proper focal point position, the card push rod 9 needs to be adjusted in length during the rotation process, and the length of the card push rod 9 can be adjusted by the expansion and contraction of the telescopic arm 92 in the telescopic groove. When the card push turntable 91 rotates, the telescopic arm 92 and the rotor 11 also rotate. Since the rotor 11 is always in the track groove 10, the extension and retraction of the telescopic arm 92 can be controlled by the design of the track line of the track groove 10. The rotor 11 is rotatably connected to the telescopic arm 92, which is mainly subjected to rolling friction when moving in the track groove, and the friction force is small, so the overall operation of the device is smoother.
