Knitting process for longitudinal wrapping of high-speed knitting machine

Abstract

The invention discloses a knitting process for longitudinal wrapping of a high-speed knitting machine. A positioning plate, a limiting frame, a bending strip, an airplane way and a forming cylinder are included, a plurality of positioning holes are transversely formed in the lower portion of the side surface of the positioning plate, the limiting frame is installed on the positioning plate through the positioning holes, the airplane way is installed at the upper end of the positioning plate, a receding circular groove is formed in the installation position of the airplane way and the positioning plate, the bent strips are installed on the two sides of the receding circular groove, the forming cylinder is fixed to the upper end of the airplane way, and the technology comprises the steps of feeding, flattening and pre-shaping, cable entering and forming. According to the invention, the knitting process of longitudinal wrapping is further optimized, the processes of flattening, pre-shaping and step-by-step forming are added, the aluminum foil tape which is easy to deform during feeding can be flattened in advance through flattening, then the cable core is wrapped in the state that the two sides are semi-rolled, and finally the cable core is pressed and formed through the forming cylinder. The aluminum foil tape can be rounded, smooth and longitudinally wrapped on the outer side of the cable core during weaving, the longitudinal wrapping quality of the wire aluminum foil layer is improved, and the longitudinal wrapping efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of longitudinal wrapping of high-speed braiding machines, and in particular relates to a weaving process of longitudinal wrapping of high-speed braiding machines. Background technique [0002] In the coaxial cable structure, in many cases, the outer conductor adopts the structure of aluminum foil longitudinal wrapping and metal alloy wire braiding, which is completed once on the high-speed braiding machine in the braiding process. Directly related to the mechanical properties, service life and safety performance of the cable, the wrapping of the tape is generally divided into wrapping and longitudinal wrapping. [0003] However, the existing technology has not optimized and improved the longitudinal wrapping process. Most of the longitudinal wrapping still adopts a cylindrical structure to directly wrap the conductor layer or the cable core longitudinally with the aluminum foil tape. The aluminum foil tape i...

AI Technical Summary

Problems solved by technology

It solves the technical defect of the prior art that the cable core and metal composite lead after compression are easily dislocated, resulting in the separation of the core strip, and effectively improves the production efficiency and the quality of the cable

[0005] The above-mentioned patent is an improvement made on the cylindrical structure of the conventional braided longitudinal wrapping, which can solve the problem of easy misalignment of the cable core and the metal composite introduction, but this improvement has no good effect on the aluminum foil strip itself in the longitudinal wrapping. The tape is light and thin, and because the force of winding is easily affected by the winding during feeding, the problem of twisting and flipping occurs. The above-mentioned patent cannot correct the aluminum foil tape, resulting in folds and folds on the outside of the aluminum foil tape during longitudinal wrapping, and the surface is not smooth, making the cable core Longitudinal package is not round
