The invention discloses a reinforcer continuous coating and continuous extruding butterfly cable production process and equipment and a butterfly cable. The production process comprises the steps of:heating three reinforcers at the same time; carrying out surface EAA coating on the three reinforcements at the same time; cooling and curing the EAA coated on the surfaces of the three reinforcements; pulling the three reinforcements after surface EAA curing to a sheath molding extrusion die, and molding the optical cable by using extrusion molding pressure, wherein when the three reinforcementswith the cured surface EAA are arranged in a mold core of the sheath molding extrusion mold, the sheath material fully plasticized in the mold core melts the EAA and is bonded with the sheath material. According to the invention, the three reinforcements are heated to ensure that the reinforcements are fully bonded with the EAA, and meanwhile, when the three reinforcements of which the surfaces are cured by the EAA are arranged in the mold core of the sheath molding extrusion mold, the sheath material fully plasticized in the mold core enables the EAA to be quickly melted and bonded with the sheath material, so that the production efficiency can be greatly improved, and the bonding strength of the reinforcer and the sheath after the optical cable is formed is ensured.
Description
technical field [0001] The invention relates to the technical field of optical cable processing, in particular to a production process, equipment and butterfly cable for continuous coating and extrusion of reinforcement members. Background technique [0002] The butterfly cable is a new type of user access optical cable. According to the application environment and laying conditions, the optical cable structure and various technical parameters are reasonably designed, and it combines the characteristics of indoor flexible optical cable and self-supporting optical cable. Butterfly cable is the best candidate product for FTTX network solutions, and it plays a unique role in the establishment of intelligent buildings, digital communities, campus networks, local area networks and other networks. [0003] The butterfly cable is usually equipped with three reinforcements during production. After each reinforcement is coated individually, it is released and extruded in the butterfl...
