The invention relates to the technical field of ePTFE membrane production, in particular to a guide device for continuous production of ePTFE microporous membranes, which comprises a pushing die head and a guide flat plate, the width of the guide flat plate is gradually increased from one end to the other end, a guide cavity with two open ends is arranged in the guide flat plate, the guide flat plate is fixed with the side surface of the pushing die head, and the guide flat plate is fixed with the guide cavity. The guiding cavity is used for guiding materials extruded by the pushing and extruding die head, and the guiding flat plate is provided with an adjusting mechanism used for adjusting the discharging width of the extruded materials in the guiding cavity. The width of pushed materials can be adjusted when the guiding flat plate is discharged, follow-up calendaring operation of entering calendaring equipment is facilitated, meanwhile, the guiding flat plate is guided in a closed cavity guiding mode, the g
