Description

Mahjong scraping device and mahjong shuffling large-disc linkage type mahjong machine

Technical Field

The utility model relates to the technical field of mahjong machines, in particular to a mahjong machine with a mahjong scraping device and a large shuffling disc in linkage.

Background

In a conventional mahjong machine, the tile scraping device is usually fixedly arranged, the shuffling large plate rotates during shuffling, and a scraping arm of the tile scraping device plays a role in blocking and guiding mahjong tiles on the shuffling large plate, so that the mahjong tiles on the shuffling large plate are promoted to move towards the tile feeding port.

The fixed type card scraping device has the following defects:

(1) when the mahjong shuffling starts, all the mahjong tiles fall on the upper surface of the mahjong shuffling large plate at a time and are accumulated, and the scraping arm which is relatively static causes very large resistance to the mahjong tile stack, so that the movement resistance of the mahjong shuffling large plate is very large, the mahjong shuffling large plate is driven by a motor with large torque, and the cost of the mahjong machine is improved; meanwhile, when mahjong tiles are piled up to cause congestion, the motor with large torque easily damages the linkage gear mechanism.

(2) The mahjong tile stack has very large resistance to the scraping arm, so that the scraping arm is easy to deform, the requirement on the material performance of the scraping arm is high, the scraping arm fails due to too large deformation along with the increase of time, and mahjong tiles cannot reach the tile outlet and cause faults.

(3) Due to the blocking and guiding of the fixed scraping arm, the mahjong tiles can rapidly slide to the mahjong tile feeding port, stacking is formed at the mahjong tile feeding port, each mahjong tile feeding port can only adsorb one mahjong tile, the mahjong tiles are stacked at the mahjong tile feeding port, so that the interaction force between the mahjong tiles is large, the magnetic attraction force of the mahjong tile feeding mechanism is insufficient to enable the mahjong tiles to be separated from the mahjong tile stack, the idling phenomenon of the mahjong tile feeding mechanism occurs, and the mahjong tile feeding efficiency is low.

(4) During the rotation of the shuffling big disk, the free end of the scraping arm is deformed due to the large resistance of the mahjong tile stack, and large noise is generated during the process that the deformed free end of the scraping arm is quickly recovered after passing through the mahjong tile stack; in addition, since the scraping arm is fixed, the mahjong tile shuffling large disc rotates, and impact noise is generated between the mahjong tiles and the scraping arm.

In order to solve the technical defects of the fixed type mahjong scraping device, the prior Chinese invention patent (CN112121397A) of the applicant discloses a mahjong machine with a mahjong scraping mechanism and a large shuffling disc linkage type, and expected technical effects are achieved.

The shuffling large plate, the driven gear ring 11 and the first transmission gear ring 12 in the structure result in higher axial height of the shuffling large plate, and the axial height of the shuffling large plate results in thicker thickness of the mahjong table. In addition, when the shuffle large disc is processed, two inner gear rings need to be processed, and the production and manufacturing cost is high.
