They are used to form armoring of aluminum-magnesium alloy strips and stainless steel strips for armored optical cables, power cables, control cables, etc. with copper cores, aluminum cores and glass fiber cores of various specifications. The process of armored optical cable surface forming is to use steel strips or aluminum strips to form a metal protective layer on the surface of optical fibers and cables (wrapping, winding). Its function is to greatly improve the lateral pressure resistance of the optical fiber itself without affecting the optical properties of the optical fiber itself, and to prevent damage caused by mechanical forces; it can resist impact and prevent rat bites; and extend the service life of the optical cable.

[0034] Reference Figure 1 and Figure 2The working principle of the fully automatic optical fiber core flexible metal sleeve high-speed armoring machine of the present invention is as follows: the optical fiber motor drives the optical fiber disk 2 to rotate and discharge the material, and the optical fiber core 9 (i.e., the core) passes through the main template 6 along the guide tube 11. The main motor 8 drives the main template 6 to rotate through the main sleeve driving gear 81 and the main sleeve driven gear 82, and the steel belt disk 62, the guide pulley 7 and the needle rod 65 all rotate with the main template 6.

When the optical fiber core 9 crosses the steel belt 91 at the outlet, multiple needle rods 65 squeeze the steel belt 91, and flexibly wind the steel belt 91 to form a metal sleeve. At the same time, the metal sleeve is sleeved on the optical fiber core 9 to form an armored optical cable.

[0035] The fully automatic optical fiber core flexible metal sleeve high-speed armoring machine of the present invention rotates and conveys the optical fiber core 9 through the optical fiber reel 2. At the same time, a pair of guide wheels 7 clamp the conveying steel belt 91, so that the optical fiber core 9 crosses the steel belt 91, and multiple needle rods 65 are used to extrude the steel belt 91, so that the steel belt 91 is flexibly wound to form a metal sleeve and is sleeved on the optical fiber core 9 to form an armored optical cable. During the flexible winding of the steel belt 91, the steel belt reel 62, the guide wheel 7 and the needle rod 65 rotate together with the main template 6, thereby improving the armoring speed (up to 2000r / min), efficiency and stability of the optical cable, and reducing the armoring cost.

[0036] Reference Figure 1 and Figure 2 , a method for armoring an optical cable, the armoring method is based on the above-mentioned fully automatic optical fiber core flexible metal sleeve high-speed armoring machine, and the armoring method comprises the following steps:

[0037] Step 0: Pass the optical fiber core 9 on the optical fiber reel 2 through the guide tube 11 and out from the outlet of the main template 6, and pass the steel belt 91 on the steel belt reel 62 around a plurality of steel belt guide wheels and a pair of guide wheels 7 in sequence and cross the optical fiber core 9;

[0038] Step 1: The optical fiber motor controls the optical fiber disc 2 to rotate and discharge the material, so that the optical fiber core 9 is transported to the main template 6 along the guide tube 11;

[0039] Step 2; the molding motor 3 controls a pair of guide pulleys 7 on the main template 6 to rotate in the opposite direction (such as Figure 2 ), clamping and conveying the steel belt 91 on the steel belt reel 62 to the outlet of the main template 6;

[0040] Step 3: The main motor 8 controls the rotation of the main template 6 through the main sleeve driving gear 81 and the main sleeve driven gear 82, so that the steel belt reel 62 and a pair of guide wheels 7 rotate together with the main template 6. Under the squeezing action of multiple needle rods 65 on the main template 6, the steel belt 91 is wound around the optical fiber core 9 to form an armored optical cable.

[0041] The optical cable armoring method of the present invention uses multiple needle rods 65 to extrude the steel belt 91 that crosses the optical fiber core 9, so that the steel belt 91 is flexibly wound to form a metal sleeve and is sleeved on the optical fiber core 9 to form an armored optical cable. At the same time, the steel belt reel 62, the guide wheel 7 and the needle rod 65 rotate together with the main template 6, thereby improving the armoring speed (up to 2000r / min), efficiency and stability of the optical cable.
