Introducing device for longitudinal wrapping and pressing technology of metal composite belt

Abstract

The invention relates to an introducing device for a longitudinal wrapping and pressing technology of a metal composite belt. The introducing device comprises a bottom plate, a pipe barrel and a cavity inserting plate; a longitudinal groove is formed in the surface of the inner wall of the pipe barrel in a penetrating mode, the cavity inserting plate is movably inserted into the longitudinal groove, and a hole groove used for allowing a cable core to pass is integrally formed in the lower end of the cavity inserting plate. The introducing device is simple in structure, reasonable in design, high in practicability, low in manufacture cost, solid and durable; the longitudinal groove is formed in the surface of the inner wall of the pipe barrel in the penetrating mode, the cavity inserting plate is movably inserted into the longitudinal groove, therefore, the technical defect that in the prior art, core and belt separation is caused due to the fact that dislocation is prone to be generated when the wrapped and pressed optical cable core and the metal composite belt are introduced is overcome, and the production efficiency and the optical cable quality are effectively improved.

Description

technical field [0001] The invention belongs to the field of optical cable processing, and relates to the process of longitudinal encapsulation of optical cables, in particular to an introduction device suitable for the process of longitudinal encapsulation of metal composite tapes. Background technique [0002] Optical cables are widely used in electric power and communication industries. In the production process of optical cables, the cable core needs to be longitudinally wrapped with metal composite tape, that is, the two sides of the steel tape are lapped and pressed together, so that the steel tape is wrapped around the outer periphery of the cable core. However, there are some defects in the existing production process: [0003] 1. In the longitudinal wrapping process, due to the certain hardness of the metal composite tape, the metal composite tape cannot longitudinally wrap the cable core of the optical cable well, so that the wrapped optical cable core and the meta...

AI Technical Summary

Problems solved by technology

[0003] 1. In the longitudinal wrapping process, due to the certain hardness of the metal composite tape, the metal composite tape cannot longitudinally wrap the cable core of the optical cable well, so that the wrapped optical cable core and the metal composite tape are easy to separate and misplace. affect the technical process, and even cause safety hazards to the equipment

[0004] 2. Since the two sides of the metal composite tape cannot be effectively limited and guided during the longitudinal wrapping process, after the optical cable is longitudinally wrapped, the overlap of the two sides of the metal composite tape is not firm, and misalignment is prone to occur. When the speed is fast, it will cause the metal composite belt to lag behind, or even get stuck in the leading device
