EPS (Expandable Polystyrene) foam pre-foaming equipment

The utility model relates to the technical field of foam production, in particular to EPS (Expandable Polystyrene) foam pre-foaming equipment, which comprises a pre-foaming tank, a pre-foaming tank, a pre-foaming tank, a pre-foaming tank and a control system, the multiple sets of stirring rods are fixedly connected with the rotating shafts, and impact blocks are elastically arranged at the ends of the multiple sets of rotating shafts; the filter plate is arranged between two adjacent groups of stirring rods; the device has the beneficial effects that the motor and the rotating shaft are matched to drive the multiple groups of stirring rods to synchronously rotate so as to drive the elastically arranged impact block to rotate, when the elastically arranged impact block touches the abutting rod, regular stretching can be formed, the inner wall of the pre-foaming tank is regularly impacted, foam adhered to the inner wall of the pre-foaming tank is shaken off, and meanwhile, the foam is prevented from falling off
