Sealing dipping pultrusion system device for producing optical fiber reinforced core and preparation method

Abstract

The invention discloses a sealing dipping pultrusion system device for producing an optical fiber reinforced core and a preparation method. The device is characterized in that a heat moisture removing device, a seal pressure dipping device, a heat molding mold, a mechanical traction device and a rolling reel device are arranged at the right side of a guide creel in sequence, the upper end of a transparent sealing glue storage tank is connected with a glue inlet through a 1# valve and a pipeline; the lower end of the transparent seal glue storage tank is connected with the seal pressure dipping device through a 2# valve and a pipeline; the bottom of the seal pressure dipping device is connected with a glue outlet through a 3# valve and a pipeline; and the tail end of the seal pressure dipping device is connected with a vacuum pump through a 4# valve and a pipeline. The device provided by the invention is simple in structure, pollution-free for atmosphere, harmless for bodies of workers, and the harmful gases in glue material cannot be volatized; the product is strong in corrosion resistance, resistant to rust, free from nitrogen damage, does not affect the signal propagation performance of optical fiber, is insensitive to electric shock and long in service life. The product has no air gap, is large in density, high in strength and excellent in performance, thus, the device can be widely used for the manufacturing industry of optical fiber communication.

Description

technical field [0001] The invention relates to a device and a method for a strengthening core of an optical cable, in particular to a device and a preparation method of a sealing and dipping pultrusion system for producing a strengthening core of an optical cable. Background technique [0002] In order to enhance the tensile strength of the communication optical cable, a strengthening core material is set inside the optical cable. figure 1 Shown is the structural diagram of the existing communication optical cable. There are five five-core optical cables inside the optical cable. A strengthening core is arranged in the center of the five five-core optical cables. The outer diameter of the five-core optical cable is covered with a loose tube. There is a casing filler connected between the optical cables, and a cable core filler is connected between the loose tube and the loose tube. There is a polyethylene sheath connected to it. In the past, steel wire was generally used a...
