Tempered glass production system, tempered air grid and air outlet unit

According to the tempered glass production system, the tempered air grid and the air outlet unit, when the curvature of a glass plate changes, the telescopic end stretches out and draws back in the vertical direction, so that the air outlet head is driven to move in the vertical direction, and meanwhile, the air outlet head can rotate relative to the telescopic end under the action of external force; the position of the air outlet head can be further adjusted, so that the trajectory of the high-speed low-temperature airflow ejected from the air outlet in the air outlet head is perpendicular to the curved surface where the glass plate is located or the angle error between the trajectory of the high-speed low-temperature airflow ejected from the air outlet and the curved surface where the glass plate is located is within 0-15 degrees; therefore, the tempered air grid can adapt to the curvature change of the glass plate, and the universality of the tempered air grid is enhanced.
