Polymer lithium battery edge-sealing equipment

The utility model discloses a polymer lithium battery edge-sealing equipment. The equipment comprises an upper sealing head and a lower sealing head, wherein a first limited block, a straight plate matched with the front end surface of the lower sealing head, is arranged on the front end surface of the lower sealing head; a second limited block, which is a folded plate matched with the side surface of the lower sealing head, is arranged on the side surface of the lower sealing head. The polymer lithium battery edge-sealing equipment has an ideal edge-sealing effect, restricts not only the compression degree of aluminum-plastic films but also the fusion degree of the aluminum-plastic films, enables the fusion effect between the aluminum-plastic films to be more stable and consistent, well guarantees the edge-sealing performance of the polymer battery, prevents the aluminum-plastic films from excessive compression and fusion, and ensures that rupture of the sealed edge of an edge-sealed battery due to expansion
