Description

TECHNICAL FIELD

[0001] The application relates to the technical field of tension detection, in particular to a pay-off tension detection device. BACKGROUND

[0002] In a cable manufacturing process, an insulating sleeve is generally wrapped around or longitudinally wrapped on a wire core, specifically, a wire is continuously pulled out from each wire reel through a pay-off mechanism, so that each wire can be continuously passed through a stranding device and then sent into an extrusion device after being stranded into a wire core, and meanwhile, an insulating material is extruded through the extrusion device to form an insulating sleeve wrapped on the wire core. However, the inventor finds that, since the diameter of the wire reel is continuously reduced during the pulling of the wire, the resistance of the wire during the pulling process will change continuously, which leads to the change of the tension of the wire during the conveying process, and thus greatly affects the conveying speed of the wire, so that the wires in the wire core are unevenly stressed during the extrusion molding of the insulating material, thereby affecting the final yield of the cable.
