Description

Automatic mahjong machine upgrade system

The present invention relates to a system for a mahjong machine, and more particularly to an upgrade system for an automatic mahjong machine.

The automatic mahjong machine is to be automated. It only needs to operate the automatic mahjong table work program. Then the pre-built mahjong tiles in the mahjong machine will be lifted to the table through the push-up machine inside the fuselage, and people can continue. Fighting is fast and effortless.

Referring to Fig. 1, there is an upgrade system 9 for an automatic mahjong machine. The upgrade system includes a lifting plate 91 hinged at one end to the table body. The lower end of the lifting plate 91 is provided with a guiding seat 92. The end surface 921 of the guiding seat is curved. And a straight face structure, a mounting seat 93 and a swinging rod 94 rotatably connected to the mounting seat 93 and having one end in contact with the end surface 921 of the guiding seat 92 are disposed under the lifting plate 91. The swinging rod 94 is driven by a lifting motor 95 to perform reciprocating operation. When the swinging rod 94 moves toward the straight end of the end surface 921 of the guiding seat 92, pushing the guiding seat 92 urges the lifting plate 91 to flip upward with respect to the table body 90 until the swinging rod 94 abuts the straight surface of the guiding seat 92, The surface of the lifting plate 91 is flush with the table top. When the pendulum rod 94 moves toward the side of the curved surface, the lifting plate 91 is turned downwards under the action of gravity, forming a passage for the mahjong card to enter the table from the table body.

The disadvantage of the prior art is that the lifting plate 91 automatically flips into the inside of the table body by its own gravity to form a slanting channel, but the side wall of the lifting plate 91 and the table body are completely fitted, so that the lifting plate and the table body are relatively large. The frictional force causes a large hindrance to the downward turning of the lifting plate 91, and it is easy to cause the lifting plate 91 to be unable to be turned over or the carton's flipping into the table body, which affects its normal operation.

Therefore, the object of the present invention is to provide an upgrade system for an automatic mahjong machine whose lifting plate can be easily and evenly flipped relative to the table.

Therefore, the upgrade system of the novel automatic mahjong machine comprises a lifting plate for one end hinged with a table body, a mounting seat disposed below the lifting plate, and a swinging rod pivotally connected to the mounting seat a lower end of the lifting plate is provided with a guiding seat, the lower end surface of the guiding seat is formed by an arc surface disposed toward a side of the lifting plate hinge and a straight surface facing the other side of the lifting plate, the pendulum end is opposite to the The lower end of the guiding seat is in contact with each other, and the other end of the swinging rod is driven to reciprocately swing by a driving device. The swinging rod is provided with a rotating member toward one end of the guiding seat, and a sliding rail is disposed at a lower end of the lifting plate. The guiding seat is disposed in parallel in a vertical direction and forms a passage for the rotating member to slide along the length of the lifting plate with the lower end surface of the guiding seat, and the rotating member interferes with the sliding rail during the swinging of the swinging rod The slide rail exerts a pulling force that moves downward.

The utility model has the following effects: when the lifting plate is turned upside down relative to the table body, the swinging rod is driven by the driving device to perform a reciprocating swing operation with respect to the mounting seat, so that the other end of the swinging bar is centered on the mounting seat along the lifting The plate is circularly reciprocated, and at the same time, when the rotating member abuts against the lower end surface of the guiding seat and the inner wall of the sliding rail to move the rotating member toward the hinge side of the lifting plate, the rotating member The sliding rail forms a pulling force, so that the lifting plate is driven to rotate at a constant center toward the inside of the table body at the center of the hinge; when the swinging rod is driven to swing from one side of the curved surface toward the straight side, the rotating member is opposite to the guiding seat The lower end surface forms an abutting force, and the uniform speed drives the lifting plate to face upward until the rotating member abuts the straight surface of the guiding seat, so that the end surface of the lifting plate is flush with the end surface of the table body, thereby completing the entire turning operation of the lifting plate. The driving plate can be driven to rotate up and down relative to the table body at a constant speed, thereby avoiding the effect that the lifting plate is stuck and the working efficiency is improved.
