How Should The Automatic Mahjong Machine Not Push Cards?

Mechanical and electrical components without push action:

1, the photoelectric sensor S1 on the pushing mechanism of electromechanical components is blocked by foreign matter.

2, the variable value of the potentiometer that determines the working state of S1;

3, the working condition of S1 is not up to the requirement, and the sensitivity is too low. We should adjust the potentiometer of S1 to make it meet the requirement.

4, the card is too dirty, so that the function of S1 shorter distance;

5, mechanical and electrical components of the motor plug loose or broken line;

6, electromechanical components or motors or phase shifting capacitors are damaged or changed.
