Centering control device for mahjong tiles

Abstract

The invention relates to a centering control device for mahjong tiles, which comprises a motor, a reel spring, a rack, a tile feeding plate, a driving gear, a transmission shaft, a one-way bearing and a first driven gear all arranged on a rack, wherein the rack is arranged on the rack in a sliding manner; the tile feeding plate is hinged with one end of the rack; the reel spring is elastically connected with the rack and the driving gear; the transmission shaft is rotationally arranged on the rack; one end of the transmission shaft is connected with the first driven gear through the one-way bearing, and the other end of the transmission shaft is in transmission connection with the motor; and the driving gear is in transmission connection with the first driven gear at the same time of being engaged with the rack. The device uses the opposite rotation of the corresponding motor to drive, so that the utilization efficiency of the motor is improved, and the cost of a mahjong machine is reduced; the travel of the tile feeding plate is controlled by controlling the opposite rotation time of the motor, and the centering requirements of the mahjong tiles with different lengths on a tile receiving plate can be satisfied without adjusting the matching relation among all parts; and the tile feeding plate of the device is not required to be exchanged frequently.

Description

technical field [0001] The invention relates to the field of mahjong machines, in particular to a centering adjustment device for mahjong tiles. Background technique [0002] The mahjong tiles in the shuffling drum of the existing mahjong machine are absorbed by the sucking mechanism and transported to the tile receiving seat by the card suction mechanism, and after the two tile bases are stacked on the tile receiving seat to form a trick, they are pushed to the receiving tile by the pushing head Board, the cards on the receiving board are continuously moved forward by the push of the next trick until the set number of tricks is reached. In this case, the mahjong tiles on the card receiving board are biased towards one end of the receiving card holder, and the cards in this situation on the receiving board are pushed from the pushing board to the ascending board in parallel, so that the cards on the ascending board are also biased towards the end of the board. One end, bu...

Problems solved by technology

In this case, the mahjong tiles on the card receiving board are biased towards one end of the receiving card holder, and the cards in this situation on the receiving board are pushed from the pushing board to the ascending board in parallel, so that the cards on the ascending board are also biased towards the end of the board. one end, not centered

What's more unfavorable is that the mahjong tiles used in mahjong machines all have magnetic substances, which are generally heavier.

Therefore, the long-term uneven stress on the lifting board often causes deformation.

[0003] In order to overcome the above problems, the applicant in this case once proposed an invention patent application with the patent application number 2011102590616, combining figure 1 The specific technical scheme is as follows: groove in the middle part of the card receiving plate B6, drive the rack B2 to slide under the slot in the middle part of the card receiving plate through the motor-driven half gear B1, and the end of the rack is hinged with the card feeding plate B3, The card board B3 stands up under the pull of the rack and drives the cards on the receiving board to the middle for a certain distance, so that the mahjong tiles on the receiving board are centered; The length of the mahjong tiles on the card receiving board is also different. In order to realize the centering function, the stroke that the card sending board needs to travel is also different. It is necessary to adjust the matching relationship between the rack head B4 and the rack B2 that are half connected to the card sending board To change the stroke of the card delivery board, it is more troublesome to use in practice; and the above-mentioned technical scheme needs to occupy a motor separately, and the utilization rate of the motor is low, thereby increasing the cost of the mahjong machine; Only when the flat bottom surface B5 fits perfectly with the upper edge of the chute can it realize its function of standing up vertically and then pushing cards. In actual use, the card feeding plate is not completely vertical or In the process of sliding along the upper edge of the chute, one side of the bottom surface of the card plate will be severely worn, so that the angle between it and the chute will gradually change when it is standing up until it cannot stand up at last, which is not conducive to the stable realization of the centering function of the device. It is necessary to replace the card feeding plate in real time according to the wear condition of the bottom surface
