Description

Technical Field

[0001] The utility model relates to the technical field of graphite paper reverse winding equipment, and specifically discloses a graphite paper reverse winding mechanism. Background Art

[0002] Graphite paper is a kind of graphite product, which is made by chemically treating high-carbon phosphorus flake graphite and rolling it at high temperature. Graphite paper is the basic material for manufacturing various graphite seals. During the production process of graphite paper, the original materials need to be put into an expansion furnace. The materials expanded by the expansion furnace enter the production line through pipelines for cooling and a blanking device, and then undergo automated pre-pressing and fine-pressing operations. Finally, qualified graphite paper products are produced by a paper winder.

[0003] Graphite paper usually needs to be dried in a relatively dry environment to make the production quality of graphite paper meet the production standards; after drying, graphite paper needs to be reverse wound. Specifically, the graphite paper is reverse wound from the graphite paper reel temporarily storing the graphite paper to an empty reel; after the graphite paper is reverse wound to the empty reel, it is convenient for subsequent storage and transportation. Currently, during the reverse winding process of graphite paper, multiple people are generally used for cooperation, resulting in low work efficiency and a great waste of manpower; and during the reverse winding process, the offset is often large, resulting in situations such as tearing of the graphite paper, and the quality cannot be guaranteed, thus causing great economic losses to the enterprise.
