Embodiment Construction

[0019] Embodiment: single-bundle tube adds water-blocking tape vertically wrapped optical cable sheath one-time forming manufacturing process, and this process comprises the following steps successively:

[0020] a. Color the optical fiber first;

[0021] b. The optical fiber is made into a bundle tube by the plastic coating process, and then 8 water-blocking glass fiber yarns are wrapped outside the tube tube; casing.

[0022] c. Then wrap the water-blocking tape vertically outside the water-blocking glass fiber yarn;

[0023] d. Then realize the one-time molding of yarn binding, tearing rope and sheath outside the water blocking belt, and complete the manufacture of optical cable. In this step, the above functions are realized by installing a yarn binding machine capable of winding binding yarn and tearing rope on the processing sheathing equipment, and through human control, the one-time binding of yarn binding and sheathing after the water blocking tape is wrapped longit...

Abstract

The invention discloses a one-shot forming manufacturing process for a single-beam-tube longitudinally-wrapped-water-blocking-tape cable sheath and a product thereof. The process is implemented as follows: step a, coloring identification is carried out on a fiber; step b, a fiber is manufactured into a beam tube by using a coating technology and then eight water-blocking glass fiber yarns coat the outside of the beam tube; step c, a water-blocking tape wraps the outsides of the eight water-blocking glass fiber yarns longitudinally; and step d, one-shot forming of fastened yarns and a sheath is realized outside the water-blocking tape, thereby completing cable manufacturing. According to the invention, one-shot forming of fastened yarns and the sheath is realized, so that the productivity efficiency is improved, equipment is simplified, and the turnover time and manufacturing cost of the semi-finished product are reduced.

Description

technical field [0001] The invention relates to a one-time molding manufacturing process of an optical cable sheath and a product thereof, belonging to the field of communication optical cable manufacturing. Background technique [0002] In the existing optical cable manufacturing process, the longitudinal wrapping structure of the water-blocking tape is to fix the water-blocking tape by adding a tying yarn in the cable forming process, and then set a sheath on the tying yarn. Due to the separation of yarn binding and sheathing processes, the production efficiency of optical cable production is reduced, the turnaround period of semi-finished products and manufacturing costs are increased, and it is difficult to strictly control product quality in the multi-channel production process. Therefore, how to develop a process to realize yarn binding and sheath forming at one time has become an urgent issue in the industry. Contents of the invention [0003] The object of the pre...
