Edge folding and heat sealing device for medical mask production and fusion method thereof

The invention discloses an edge folding and heat sealing device for medical mask production and a fusion method thereof, and relates to the technical field of medical mask production. The problems that an edge folding and heat sealing mechanism used for existing medical mask production is usually independent equipment, only can process cut independent mask pieces, and is low in adaptability to anassembly line are solved. The edge folding and heat sealing device comprises a first rack, wherein a second rack is installed at the front end of the first rack, a belt conveyor is arranged at the front end of the second rack, supporting frames are installed on the two sides of the upper surface of the first rack, an outer-layer non-woven fabric unwinding wheel is installed between the supportingframes, a middle melt-blown fabric unwinding wheel is arranged at the front end of the outer-layer non-woven fabric unwinding wheel, an inner-layer non-woven fabric unwinding wheel is arranged at thefront end of the middle mel
