Pushing-elevating mechanism for full-automatic mahjong machine

Abstract

The invention relates to a pushing-elevating mechanism for a full-automatic mahjong machine. The pushing-elevating mechanism comprises an pushing-elevating main body frame, a mahjong push plate, an elevating platform, a driving device, at least two peach-shaped wheels and active oscillating bars with the same number as the peach-shaped wheels, wherein the elevating platform is arranged on the pushing-elevating main body frame in a manner that the elevating platform can slide upwards and downwards; the contact surface of each peach-shaped wheel comprises a bottom plane and two sloping surfacesformed on the bottom plane and connected with each other at a highest position; the at least two peach-shaped wheels are bilaterally symmetrically arranged below the mahjong push plate; one end of each active oscillating bar is hinged with the pushing-elevating main body frame while the other end is fixedly connected with the mahjong push plate; a bearing is rotatably arranged in the middle of the active oscillating bar and is pressed against the contact surface of the peach-shaped wheel; and the at least two peach-shaped wheels are in transmission connection with the driving device. Inclination of mahjong pushing can be avoided and action stability can be improved.

Description

technical field [0001] The invention belongs to the field of fully automatic mahjong machines, in particular to a push-up mechanism of the mahjong machine. Background technique [0002] At present, the push-up mechanism of many automatic mahjong machines on the market is driven by a motor to rotate a special-shaped cam with an eccentric center in the middle. The active pendulum moves reciprocatingly on the shape of the special-shaped cam, so as to realize the purpose of moving the card pushing plate back and forth. [0003] The technical defect of this structure is: since the single special-shaped cam is arranged in the middle position of the rotating shaft, if the stress point of the special-shaped cam and the bearing deviates, there will be a deviation in the thrust of both sides, and the situation of pushing the card is prone to inclination; further , Mahjong tiles are played differently across the country, and the number of tiles is also different. When the number of ti...

Problems solved by technology

[0004] In order to overcome the deficiencies of the existing mahjong machine push-up mechanism, which tends to cause tilting and poor stability, the present invention provides a push-up mechanism for a fully automatic mahjong machine that avoids tilting the tiles and improves the stability of the action.
