The invention provides a foaming equipment detection system. The foaming equipment detection system comprises a raw material library, a mixer, an extruder, a foaming machine, a cooling shaping deviceand a detecting and controlling unit. On one hand, the detecting and controlling unit simultaneously detects temperature changes inside the foaming machine equipment and other equipment on a foaming production line, for the temperature change inside the foaming machine, the detecting and controlling unit can determine a specific fault generation point in a layer-by-layer diagnosis mode, which facilitates the maintenance of the equipment on the whole production line and the precise control over the temperature inside the foaming machine; and on the other hand, the detecting and controlling unitof the foaming equipment detection system can adjust the pressure value changed due to temperature change inside the foaming machine while adjusting the temperature inside the foaming machine, so that the adjusting step is reduced, and the adjusting time is shortened.
