Tile-sucking disc device

Abstract

The invention relates to a tile-sucking disc device which comprises a tile-sucking disc and magnets, wherein the tile-sucking disc comprises a base part and a splicing part; the circumferential sides of the base part and the splicing part are respectively provided with three first grooves and three second grooves which correspond to each other and uniformly distributed; the base part and the splicing part are spliced to each other in the axial direction; after the base part and the splicing part are spliced, magnet grooves which are uniformly distributed and are composed of corresponding first grooves and second grooves are formed on the circumferential sides; the included angle between the center line in the length direction of each magnet groove and the axial line of the tile-sucking disc is an acute angle alpha; and the magnets are arranged in the magnet grooves. The invention has the following advantages: 1) in the tile transport process, the tiles can not be scraped down by guideplates or be stuck at the inlet end, thereby achieving high transport efficiency and ensuring the normal operation of the mahjong machine; 2) the magnets on the tile-sucking disc can be conveniently and quickly fixed, thereby improving the production efficiency of components and parts of the mahjong machine; and 3) the quantity of magnet sheets is reduced by 1 / 4, thereby saving the rare earth material and lowering the manufacturing cost.

Description

technical field [0001] The invention relates to components in a mahjong machine, in particular to a card suction wheel device. Background technique [0002] There are four belt transmission devices evenly distributed in the circumferential direction in the card shuffling cylinder in the mahjong machine, through which the shuffled cards are transmitted to the card pushing device, and then the cards are pushed into the card storage slot one trick at a time (A trick is two cards stacked face down). [0003] In order to ensure the consistency of the card surface (all up or down), the cards must be adjusted as they enter the belt drive. The method currently adopted is to place magnets in the cards, and simultaneously set corresponding magnets on the card-absorbing wheel at the end of the belt drive in the card shuffling tube, so that the mahjong cards are attracted to the conveyor belt due to the magnetic attraction. And it can guarantee that the cards face down (or up). [00...

AI Technical Summary

Problems solved by technology

The card-absorbing wheel with the above structure will have such defects when sucking cards: 1) The arrangement of the cards sucked onto the conveyor belt is quite different, and it is not convenient for the guide piece to organize and guide the cards on the conveyor belt, so that the cards can be arranged according to a set arranged in a certain direction

When the arrangement direction of the plates on the drive belt deviates greatly from the set direction, they will often be scraped off or stuck at the entrance when passing the guide plate, see Figure 12 , resulting in low efficiency of losing cards or affecting the normal work of the mahjong machine

2) The magnet is inserted into the slot by means of interference fit, which is time-consuming and labor-intensive for fixing

3) The number of magnets used on the suction wheel is large, and the price of rare earth materials is rising rapidly at present, and the price of each magnet is as high as 3 yuan. The existing mahjong machine uses 16 magnets, and the material cost is about 48 yuan
