Description

Technical Field

[0001] The invention relates to the technical field related to optical cable production, and more precisely to an automatic cooling system for an optical cable sheath sizing die. Background Art

[0002] The sheath of the optical cable is a protective layer located on the outside of the cable core. It is usually combined with the armor layer and wrapped around the outside of the armor layer. The armor layer provides mechanical protection such as tensile and compressive resistance for the optical cable, and the sheath provides waterproof, anti-corrosion and certain mechanical protection for the armor layer. The optical cable sheath needs to use a sizing die during the manufacturing process. The existing sizing dies are all mechanical tensile structures. They are wrapped around the cable core of the optical cable by gradually changing the diameter through direct contact with steel or aluminum strips. As the speed of the production equipment continues to increase, the friction between the steel and aluminum strips and the sizing die continues to increase, and the heat generation gradually increases, resulting in the sizing die being very hot and unable to cool itself, which can easily lead to an increase in the break rate due to high temperature.

[0003] In order to reduce the rate of broken wires caused by high temperature, the sizing mold needs to be effectively cooled. Due to the characteristics of the optical cable production process, it is impossible to directly cool the sizing mold with water. The cooling effect of air cooling is poor. The cooling effect of liquid nitrogen and other refrigerants is good, but the large temperature difference is easy to condense and affect the quality of optical cable products, and the cost of using refrigerants is high.

[0004] In summary, the art needs a system that can effectively and quickly cool down the optical cable sheath sizing die and has low cost. Summary of the invention

[0007] Preferably, the controller is a PLC.

[0008] Preferably, it includes a touch screen communicatively connected to the controller.

[0009] Preferably, the water cooling tube is wrapped around the outside of the sizing die.
