Mahjong machine can't afford to wash the cards. How to repair them?

Different reasons will lead to mahjong machine's failure to shuffle the cards, so we should do the elimination method first, and then carry out targeted maintenance.

The first step, the elimination is caused by automatic power failure. At this time, it is necessary to check whether the power supply is energized.

Step 2: mahjong machine's pressure plate is loose, or there is something dirty on the induction sleeve, so it is necessary to tighten the pressure plate and clean the induction sleeve.

In the third step, we need to regularly check whether the 3K4 sensor is damaged and whether the magnetic ring position is not in place. We need to make the K4 sensor sense when it sees the long-chain rod. We need to debug it to a suitable position, or find professional maintenance personnel to replace it with a new 4. We need to check whether the distance between the sensor sleeve and the sensor is about 0.5 cm. If not, we need to adjust it.

If all the above faults are eliminated, mahjong machine still can't shuffle the cards, then the mahjong sensor or magnetic stripe is broken.

Mahjong machine principle

Mahjong machine's principle is that there is no surface magnet on the back and no surface magnet on the front. The card rotates with the disk on the inclined disk. When a card rises to a high place, the card with its back facing upwards is attracted by the rotating magnetic ring above the disc, while the card with its face not facing upwards continues to rotate in the big disc, and there are generally two strong magnets below the big disc.

When the turned card is subjected to strong magnetic force, the magnet on the card repels the magnet under the big plate and turns over, and then it is sucked up by the magnetic ring and sent to the transmission slot with the rotation of the magnetic ring. When the card passes through the transmission slot, a card stacker will be responsible for folding the card into two pieces, and then push the card away through the lever after folding.

Mahjong machine was born in Japan. Mahjong machine's working principle is that the cards with the back facing upwards are attracted by the magnetic ring on the shuffling barrel, sent to the conveying trough along with the rotation of the magnetic ring, pushed into the pier by the card folding motor of the head, and pushed away by the chain rod, while the cards with the non-magnetic front face continue to rotate on the tray (single-mouth machine principle), which has been upgraded to a four-mouth machine.
